My favorite test print is the 3D Systems Rook.
2 hours on PLA with plenty of features to discern issues with your printer or filament.

At one time, 3D Systems sent me the rook to test the printer.

Anyway, since I am collecting a number of these, I thought these could become gnomes.
I was thinking we start leaving them in places we visit like Starbucks, the grocery store, DMV...

I wonder just how long it will take for you to start seeing your prints another time.

Whatever your favorite test print is, let me know what you think of this idea.

What luck... found the thingiverse version.
Odd, appears to be exactly the same as 3D Systems version :p

Working on a printed re-winder.

So far so good.
Wound a stock spool within a few minutes.

Updates from the image is a taller holder for the 3DS spool with a little less clearance.

just screw the two spool flanges to a piece of wood or bolt them into your workbench... whatever :p

A little Lego device that can layer better on the target spool would be cool.
We can drive Lego with the teeth on the 3DS spool.

Some notes:
The handle presses into the ring. It has about 10 degrees of freedom. It is snug fit, but spins easily when winding.

Xylene... that takes off just about everything. :( Horrible stuff!

And it also melts the original print-bed plastic material.

As to the plastic used, it is almost mirror polish on the adhered side.
If you can peel it off cleanly, you will probably have a clean adhesive surface to re-apply your own material.

This material is very shiny but scratches easily on the adhered side. It is 0.8mm thick (1/32"?)
It appears to have a filler. It snaps when it breaks and can leave sharp edges. S
cores easily, and breaks along score within reason.

Remember that this is an earlier material that does not pit as later versions do with ABS!

1697

The plate after some serious scouring. Wiped the plastic with xylene which now display an interesting texture.

1698

And after all that, alumina plate included, I ended up having to adhere with tape! :confused:
The alumina is just too cold to the touch, and too smooth to hold anything even using Cube-Glue.

1699

In the end, I will probably order a new plate from 3DS. This one will be a nice test unit for heating.
I have no experience with a heated bed.

Worked a little on my dual extruder profile for simplify3d and did some comparisons to cube print. Looks like I have it about right to get some good prints. Only issue is that I have to use a prime tower with simplify3d but I have a good idea of what I need to change to no longer need it.

edit- Forgot to mention that my cube glue wasn't dry when I did the simpidy3d cube and the sides were curling up since they weren't being held down

Tom, what program do you use to make the threads in your models? I'm designing something and have used a tap in the hole I want threaded, but have noticed that human error can cause the threads to not be perfect. The test bolt I put in has a slight wobble when the piece is spun. I'd like to do the threads in the model.

TommyDee
03-09-2017, 11:36 PM
I use the current version of Pro Engineer which is Creo.
I have to define the treads though.

SolidWorks '16 will now do helical threads.

So if you can do helical sweep cuts in a CAD program, WIKI has a good profile for both metric and English

I've been using tinkercad to do my model. It's cheap and easy, just the way I like it. I found that there's a metric thread generator where I just put in the diameter and pitch and it creates a model with threads on it, turn that from a solid to a hole and it's easy metric female threads through the middle of the model. I may thread chase it but I want the threaded rod on there tight so we'll see.

TommyDee
03-10-2017, 05:05 PM
I am amazed at how well this printer is doing on M5 threads. Yes, chase it due to the stop/start blob. Once chased, it takes quite a bit of pull-out torque. Obviously you should have the hole somewhat perpendicular to the print layers.

Nice find in the Tinkercad threads!!!

You do know the pilot for a metric thread is easy to calculate, right?
And for others... The pilot hole for a metric thread is the size of the thread minus the pitch.
That mean the pilot hole for an M6 x 1 thread is 5mm diameter.

Uuuuugh!!! I've been trying to tell you! HotSwap! That is what pause is for. Leave the tip in place and swap out filament in one of a number of ways. once you resume the printer, it purges in the waste tray and on it goes. It is simply a pause/resume function, but nothing rushes you to do anything. Just don't remove the hot-end.

These last few days was about conversion How do we get BFB to .Cube3

When we have a tool on hand that does what we want a generic dataset to do, I really think it is worthwhile to review what Microsoft did with their partners.

We may not have to. ...but the price is reliance on a USB interface. Many will argue the Cube's WIFI is lousy enough where USB connectivity is not a problem.

It is a device, it is recognized as a plug-n-play device through the drivers as is required by M$.

Of course, I am talking about 3D Builder and the means to communicate what 3D Builder does to print to The Qube directly.
What if we can pump a .bfb file right through to the core of the bfb conversion provided by 3D Systems themselves.
And it looks like 3D Systems provided the slicer as well, and this too is raising some opportunities.

What I found in the SDK set, and the 3D Builder app in relation to 3D Systems is that the Cube 3 is not unique in the files provided by 3DS.
It has mention of Cube 1, 2, 3, X, and Pro... and even something called COCOA(?)
And what really prompted me to give an account of my findings so far is that 3D Builder is a much improved print over the Cube dedicated app can do... I am talking 500% improvements without exaggeration!

Right now, 3D Builder passes a 3D facet model, and image, and a short ASCII XML file to the "spooler" (Microsoft managed).
It does this by storing everything in a .3MF file which is actually a .ZIP file. The 3D model is a facet file with a .model extension.
This means that the quality of the 3DS slicer in the spooling routine that is of better quality than the Cube's app.

Still with me?

3DS wanted to have a good showing with M$. You even see references to "COKEBOTTLECAP" in the DLL files referring to EKOCYCLE. This was a huge push by big players!
So did they give away the slicing farm with their proprietary slicer being made publically accessible? Chances are good they did!

So back to the code part...
Why wouldn't we be able to bypass the slicer section and force a .bfb conversion through the 3DS pipeline that M$ has established?
The SDK has a lot more files to help take this apart.

https://drive.google.com/open?id=0By-9ThR4U7GkaWViTmprSjZXbFE This is the full SDK folder zipped up.

Heh. Yeh it's gotten quiet. I've been busy and haven't even printed anything in almost 2 weeks. Haven't had a chance to look through any of the files that you've posted yet.

TommyDee
03-29-2017, 08:04 AM
Thanks... I've been printing a lot of ABS lately. I really do want to get to the bottom of this.
I'm still reviewing things on Microsoft's 3D site. It really is all well spelled out, but you need a little insider knowledge I lack.

But here's the rundown... If Microsoft forced 3D Systems to give up code that could send a g-code file to the Cube3, that would be like source code!

The thing is, you have to wrap a program around the libraries. Isn't that what you've been doing?

Anyway, I'll keep looking. So far, my Windooze10 print driver is all messed up. It now loads the driver and looses the "special" Com3 connection.

TommyDee

This still requires a lot of testing.

I bet 3DS engineers are all bald now :)

- - - - - - - - - -

The problem with plosives only came up with ABS. I have yet to see this in PLA.
And I've printed a lot with PLA using the OMG modular nozzle.
I just don't have huge stock of ABS. I have 2 stock carts and a 2kg spool of yellow.
I am just relieved at this point that the filament is not the problem.
But it does make the problem much bigger.

- - - - - - - - - -

Just a dumb thought... but why not upgrade the Cube Pro FW to work in Cube 3?

The Cube Pro software has a lot more hooks into the system, including jet temperature calibration.
Seems we could take apart the FW to include Cube Pro functionality.

TommyDee
03-30-2017, 07:54 PM
Funny. I wonder what went wrong there. The only feeder problem I've seen was getting filled will stripped material.

I am really liking the "raft" that 3D Builder makes for ABS. It sticks amazingly well that way. And it is much easier to remove from the build plate.
The only issue comes in when you want to clean up that last raft later on your part.

I have yet to learn if there is a true difference between the ABS and PLA cartridges except the little dot on the driver/feeder.

TommyDee
04-08-2017, 08:55 PM
That will do it. It could also be there is a level of restriction in the feeder line.
I've noted something about the older cartridges with the white overmold-gray nozzle housings.
When they over-molded the nylon onto the Teflon tube, they got a little too hot and created some restriction.
I keep a section of filament that as run through the feeder to check the restrictions in stock tubes.
This also accounts for restriction from the round nuts.
Some of these restrictive cartridges acted like old filament.
In fact, even though old, the filament would run fine in a good feeder system.
So there is a lot of bad bits remaining in old stock.

But the device is a solution looking for a problem.

The battery holder is just something I've needed for a long time... a way to series 2 18650 Li-ion cells.

The fabric was a test to see how I can get the 1st layer to behave in ABS.
Really tough to get a decent "fabric" that is strong enough.
I have a little chainmail version that still need to try.

Here's another I've been working on for a long time, but it has a specific requirement that I cannot source other than scrap recovery.
This was made with the remaining Esun natural PLA. Very brittle stuff, much like Hatchbox.
The flashlight is an SingFire SF348. Very popular little single mode flashlight that takes AAA or 10440 Li-Ion.

Fine... it's a linear strain gauge.

This is what happens with stock Cube 3 tubing from the cartridge to the tip.
The tubing is thin enough to become longer under pressure.

With 4mm tubing, there is less extension with a given pressure.

I am trying to solve the clicking problem during purge with some filaments.
Those skips are really bad during a print because of the sudden loss of pressure and filament.

With this tool, I can compare strain and extension of the stock tubing.

For developers, it can be used to understand the pressure provided under various conditions.

The reverse can be made for retract/de-string functions, but that may be less useful.

I am trying to solve the clicking problem during purge with some filaments.
Those skips are really bad during a print because of the sudden loss of pressure and filament.

The only time I had this clicking problem is with the original cartridge system and with my hub with a printed lid. With my hub and both halves of the metal drive mechanism, I don't have this problem at all. Also retraction is greatly improved. I have tried 3 different brands of filament, both PLA and ABS.

TommyDee
05-23-2017, 09:59 PM
It is the Hatchbox and eSun filament that has the "crispiness' added to its PLA.
It is notorious for clicking on purge and sometimes on particular print patterns.

The reasoning for pursuing this is more toward "Design Intent".
A given is that the stock tube stretches under pressure; significantly.
It is therefore also a given that the retract/de-string 1st has to release the
extended tubing back to the relaxed state before the nozzle is actually affected.

This leaves us with 2 questions:
1) Was this stretching of the tube accounted for in the retract/de-string function?
2) Was it the intent to have the tubing acts as a strain relief?

Hardware hacking efforts have been focused solely on stiffening the system.
We achieved that.
Did we introduce a new performance hit? An exploitable one?

3DS did solve compatibility issue in their systems by being the sole filament provider.
Any 3rd party filament problems does not meet specification -because- it is not OEM.

One of the patterns that caused various skip problems are first and foremost filament problems.
However, diamond patterns have a way of heating up a length of the filament in the nozzle from the repeated retract operations.
This warms up the Teflon tubing, which in turn starts a longer melt.
In the stock system, this is what gets jammed at the round nut in the nozzle, or whatever else it find to bind thing up.
It then starts clicking, -releasing filament pressure, -letting the melt cool outside the hot zone, -clicks again, -rinse/repeat.
We are not yet immune to potential issues from "over-cycling" a de-string operation. Vastly improved, yes.

I too have had much better carefree prints since giving up stock cartridges.
Or at the very least, finally knowing exactly what to look for.
It is true that many are simply junk!
Definitely worth salve though.

- - - - - - - - - -

Finally saw the 30 second "cartridge replaced" error.

More protectionist code.

Swapped out a 2% cartridge for a 0% cartridge.
It resumed the print but that prompts the error.
So there is still handshaking going on with the chip throughout the print.
More than just "present" signals.

New development of the positive kind...

When I received my 2rd replacement white printer, both cartridges were printing very thin prints and a lot of failures.
No matter how well I cleaned up the original nozzle, it just kept failing.

This white and green 3DS filament have been floating around for about 8 months.
My wife was going to try it on her weed eater.

She never did and I decided to see if this is workable in the new filament feeding systems we've all been developing here.

Sure enough! The White is printing beautifully! The neon green is printing and so far, so good.

Point being; what we often blamed as bad or old filament is actually a poor tubing system.
These were the early units with the white & gray nozzle housing.
These have a history of distorted Teflon tubing under the nylon caterpillar over-mold.
So the problem is not old filament, it is in fact bad fabrication of the tubing.

It is the Hatchbox and eSun filament that has the "crispiness' added to its PLA.
It is notorious for clicking on purge and sometimes on particular print patterns.

The reasoning for pursuing this is more toward "Design Intent".
A given is that the stock tube stretches under pressure; significantly.
It is therefore also a given that the retract/de-string 1st has to release the
extended tubing back to the relaxed state before the nozzle is actually affected.

This leaves us with 2 questions:
1) Was this stretching of the tube accounted for in the retract/de-string function?
2) Was it the intent to have the tubing acts as a strain relief?

Hardware hacking efforts have been focused solely on stiffening the system.
We achieved that.
Did we introduce a new performance hit? An exploitable one?

3DS did solve compatibility issue in their systems by being the sole filament provider.
Any 3rd party filament problems does not meet specification -because- it is not OEM.

One of the patterns that caused various skip problems are first and foremost filament problems.
However, diamond patterns have a way of heating up a length of the filament in the nozzle from the repeated retract operations.
This warms up the Teflon tubing, which in turn starts a longer melt.
In the stock system, this is what gets jammed at the round nut in the nozzle, or whatever else it find to bind thing up.
It then starts clicking, -releasing filament pressure, -letting the melt cool outside the hot zone, -clicks again, -rinse/repeat.
We are not yet immune to potential issues from "over-cycling" a de-string operation. Vastly improved, yes.

I too have had much better carefree prints since giving up stock cartridges.
Or at the very least, finally knowing exactly what to look for.
It is true that many are simply junk!
Definitely worth salve though.

- - - - - - - - - -

Finally saw the 30 second "cartridge replaced" error.

More protectionist code.

Swapped out a 2% cartridge for a 0% cartridge.
It resumed the print but that prompts the error.
So there is still handshaking going on with the chip throughout the print.
More than just "present" signals.

I blamed bad filament/carts until I did my little mod for the hot end. That's all it took for the same filament to work fine and give me good prints. I still have some 3DS filament that's printing fine now.

12-1/2 hours of print time on the Cube reduced to 7:55. I don't get it.

This one came close to the 50Mb file size limit.
3mm posts are very strong (2 layers).
Because this is the crisp Hatchbox filament, the supports came off easily.
I can see a 70um print taking 24 hours.

I used a 20 degree MeshMixer threshold; 3mm tip and 3mm diameter.

Anyone interested in making mid-sized screw driver tools for your Cube?

I ended up with a Ryobi set of bits where many are duplicates.
So I made a press-fit screwdriver handle to deal with long and short 1/4" drive tips.

I have a long filament driver (S2 square drive), long generic #2 Phillips, and the non-duplicate short 2mm, 2.5mm, 3mm, and 4mm dual end hex drives.
I guess I need a #1 Phillips also for the case screws.

Anything I am overlooking?

I can't be the first!

Going on Thingiverse at some point, but here you go...
Printed at lp12101 (Left, PLA, 200um; Strong; Cross; no Supports, yes Sidewalks)
I print these in pairs for better cooling cycles.

You might cancel the print at 1/2" (12mm) or so to see what to expect for fit.
There is a lead-in chamfer, so be patient.
These are not quick prints by any means!

2245
PrintRBot translucent orange PLA :cool:.

These are all double-ended.
Short bits for the stubby one and long bits for the handles.
The #1 Phillips works very well on the corner screws in the Cube housing.

Depending on your printer, the bits will be tight to just snug.
Don't be afraid to use a hammer if you plan to leave them configured this way.
You'll know when they hit bottom.
If the tips fall out, scale it down in Cube's Print app.

The hex in the STL file is set to 6.6mm (1/4" is 6.35mm).
You can also scale it if you need an adjustment.

Anyone is free to muck with these models.
The strength is in the toroid style construction as printed.
In addition, there are "torsion fills" in the middle.
Just thought I'd point out what you're looking at.

TommyDee
08-07-2017, 04:53 PM
Hahaha! I'll pix the next one.

That silly little piece of tube in the driver just past the gear drive.
The stubby tube that still has a barrel nut on it inside the driver, with all its angst.

There are two ways to remove this; one, drill the driver housing just the right size to firmly hold a copper tube (1/8" brass hobby tubing).
Its length is little dependent on the fitting you are using for maximum effectiveness; it will be about 11mm long.
Effectiveness is measured in successful loads; no mis-feeds.
If you drill the housing out to a full 1/8" diameter, the hole will not hold the brass tubing tightly.
In that case, you would solder some wire to the OD to make what works similar to the barrel nut.
This is option 2. Option 2 is probably more reliable and easier to manage.

I do chamfer the ID if the brass tubing. This just helps yet again.

Funny thing is, a little time here will go a long way to trouble free drivers.
From time to time, the drive gear will have to be replaced.
This is a sacrificial component that will continue to wear no matter what we do.
Lubrication (grease) will help if you don't mind the mess.

That's the problem. It is oriented to be printed with the left extruder. To print it with the right extruder, you need to rotate it 180 degrees so the blob shield is facing the right side. This will eliminate the line you are getting on the print head.

Err....which line you mean?

The vertical line running from top to bottom. Normally it would cause a blob along this line which has to be removed for it to fit. The blob shield prevents this from happening but it will not eliminate the line. Rotating this side away from the extruder eliminates the line as well. Try it and you will see what I mean. The print will be much cleaner.

It won't affect printing as long as it fits well. I was just pointing out that it would look much cleaner. If it were sticking out too much, you would have to cut it or sand it to make it fit. Apparently this is not the case for you. It can vary with different brands of filament.

New trick: gapping a dirty plate.

I have a build plate with glue slurried all over it.
It has a single layer 6" square surround printed with PLA on LokBuild.
When I wet the glue, it remains within these confines.
Makes for a nice quick certain-to-stick print bed (this LokBuild seems to be dead from day 1).

But gapping the nozzle is a PITA...
....had to auto-gap with a different build plate and switch back to the original build plate to do the manual gapping.

Kind of a D'uh! moment when I put a 17cm wide slip of printer paper on the build plate; just lying there.
Now it goes through the routine and lets you set the gap manually when the auto-gap fails.

Nice!

Now if only that would work for the leveling.

So I tried printing Taulman Bridge nylon on my Cube 3 and it works quite well. I didn't even need to use a 3rd party slicer. Just used Cube Print software and set it to ABS. Taulman Bridge prints around 250 and Cube Print software prints ABS at 260. Only slight stringing. The print could have been better but I had moisture in the filament. (This stuff picks up moisture like crazy compared to other filaments.) A lot of popping and cracking during print, but overall came out pretty good.

I couldn't either. Shipping normally kills the deal.

All registered and ready to roll. Wait... reload FW!

I may have just found a way to salvage those spent 4mm tube fittings. (http://www.print3dforum.com/showthread.php/1236-Salvage-PC4M5-fitting-Bonus?p=43820&viewfull=1#post43820)

Anyone got some ideas on how to cut a clean groove on a 4mm Bowden tube?
The more square the edge, the better. About 4mm from the end about 1.5mm wide, maybe 0.3mm deep?

- - - - - - - - - -

Finally got some ABS that works properly. I have tried 3DS ABS and it was thin and had very poor adhesion...
I tried Inland ABS and it did nothing but pop and sputter creating weak prints.
Then I try the Gold ABS from 3D Solutech which failed worse than both of the above!

So I was really moving toward the Cube 3 not being very good at ABS.

Surprise!

Remember that 3D Solutech sent me a promotional assortment of ABS.
I decided to try the clear natural ABS. I have a small project where I need "almost solid" for a bracket.
Know that "almost solid" draws 5 stripes per wall if it can.
Turns out the clear fused nearly perfectly even with the walls next to is.
It is also the best "translucent" material from a consistency standpoint.
The resulting print is nearly frosted crystal with some hotter section coming out nearly clear.
And it is strong... no layer delamination ...very few plosives (loud pops during printing).

Since I was running out of the clear (10 meter only goes so far) I backfilled it with a cool purple color.
I went and tried printing my earlier versions of the nozzle. First I tested the PLA version to make sure it was still good.
Then I printed this set in the purple ABS...
2526

Excellent hold. Testing the tower on the far side, it is perfectly pliable without cracking. That's a first for me with ABS!

Weird thing, however, is that the purple didn't stick to the clear (1st layer)! But both were a great material on their own merits. I find this intriguing.

Turns out that the ABS version is a little more "off" than the PLA version. The screw-on cap is much tighter. The M5 thread is functional but a lot "softer" than PLA. But the fact that I could force-thread the cap on the housing without it self-destructing is a testament to the better quality of this particular filament.

In all, I think I finally have a functional ABS nozzle printed on a Cube 3!

Here's a link to the file if you want it: https://drive.google.com/open?id=1cWDK1oMLPCUpIrpVwciIkeCWHonczJFK
(can't seem to upload files here anymore)

I also ordered the assortment pack of 3D Solutech's PLA so I can see how these 12 included colors behave.

This is oh-so funny that I can't help but post it.

I've printed a couple of wind spinners with bearing built into them.
It has a little printed block that it spins on and is held by a bamboo sticker.

Twice now a squirrel has chewed the bamboo to remove the spinner, and has removed the holding block from the spinner.
1st time I found the slightly nibbled plastic block a few yard away.
Today, the 2nd time, I find bits of plastic at the base of a tree and no little block.
Spinner is fine and the replacement block fixed things right up.

But what is this squirrel thinking? If you peel the plastics, it'll find a nut inside?
He/she's going to be thoroughly disappointed!

They are completely ignoring the gray spinner next to it.

Okay, I'm putting this here to keep the other stuff from getting confounded even more.

I have long desired to take apart the .cube3 files to understand how the 3D Systems slicer deals with certain aspects of slicing.
Knowing the determination of the slicer lets me take full advantage of the stock Cube 3 characteristics.

This case is particularly telling as it is unique to generic volume slicing.

Turns out that 3D Systems offsets the perimeter of your part by 0.21mm.
This logic says that if you want the trace next to the outside trace to fuse, you want the inside trace to be offset by 2x 0.21...
This means an offset of 0.42 x 2 = 0.84 is the thickness of the part in a perfect world.

Sure enough, the world is not perfect. I know, right?

But, the outside dimensions of my parts based on these numbers is within 1% of the nominal (pretty darn good!)
The wall, expected to be 0.86 came out to 0.92 consistently. I definitely expected that since I've never measured a wall much under 0.9.
Even the height came out to 4.04 (vs 4.0) even with my huge 0.23mm nozzle gap.

Anyway, this is the forensic data from code...

2596

You are looking at the original model (white) and it's dimensions, and in blue is the machine code trace based on G1 positions within the BFB file.
Notice the center offset that the Cube 3 consistently uses when you let the Cube 3 app center the parts on the printing bed.
The original STL origin is per the white outline.

Now here is the file as printed...

2597

Now here is the kicker... the two walls are beautifully fused. Surprise! <<== not really.

Now I need to test this with 4x 0.42.
Will it print with 4 traces for the wall or still only 2? What about 4x 0.41? 4 or 2 traces?
Anyone care to lay odds?

Anyone care to do some comparative testing?

- - - - - - - - - -

^ I LOVE FINALLY KNOWING THIS STUFF! ^

...but I'm weird and proud of it.

Thanks @swwinterry !

- - - - - - - - - -

Findings for 4-trace walls...

I was hoping for a slightly different result but here is the actual output.
That 0.5mm offset between traces is a problem but both of these created the very similar part;
Same actual wall thickness and same actual overall size ID/OD and Height.
One thing is remaining constant... the 0.21mm offset.

Even at 1.6mm wall, it does print 4 side-by-side traces.

2598
2599

Now to find the cutoff when it switches to 2 traces.

- - - - - - - - - -

Looks like a 1.5mm wall messes everything up. Two traces a mile apart... oh 1.08mm apart. That's 1080 microns BTW :p

2600

- - - - - - - - - -

Some comparison.

2602
2603

Obviously the 1.5mm wall didn't even come close to sticking together. Just the cross-over at the start/end corner is connected.


That tells me that I can try to optimize walls in design just a bit more. A single trace (minimum wall) will be around 0.9mm (900 microns). I can design this down to 0.08mm and I get excellent fusion between layers. Still need to test longer runs than 20mm.

For a double trace wall, I will probably stay with the 1.68mm as a minimum. The 1.6mm is identical by the naked eye but there is obviously a very small difference.

I need to do this for the almost solid too, but this is great information for me.
0.84 and 1.68 are keepers.

Yeah but which slicer? Their app?

TommyDee
04-20-2018, 08:26 PM
Oh... I get you...

No, I am using the cube3_decoder executable in Windows 7.
It's a fairly straight forward cut and paste

To be clear, the CAD images are Creo Parametric (what was once Pro|Engineer).
The slicer file is a .cube3 from the Cube3 application in Windows 7.

save the cube3 file from the Default Cube3 app.
drop the file on the executable
notepad makes quick work of the image characters below the last M107 command in the generated .bfb file
import the .bfb into Excel as text/space delimited/data type text
filter column A with "G1"
highlight columns B,C,&D ctrl-C; then paste that into notepad
in notepad, replace all characters X, Y, and then Z with nothing
optionally remove the purge point locations at the start (2) and the end (8?) of the file
save the file as a .pts file
import the .pts file into Creo CAD and do magic with the numbers

Anyway, yes, I am using what I have at hand to analyze the 3D Systems slicer.
The release of this simple decoder allowed me to do this, finally!

This method can be used for gathering any point cloud.
The software in which you want to use it will have a specific format.
The method described above will yield a space delimited series of X, Y, and Z values in Ascii.

- - - - - - - - - -

Cracked another code in the Cube App slicer...

Design element for designers:
WELL BONDED PERMIMETER WALLS FOR FLAT OBJECTS

If you want a first-layer trace-only but a solid face following, try the following in your design;
Make your trace width 1.68mm (1.7). This creates a 4-wide trace that fuses reasonably well because the center two traces are stuffed between the first two.
For the most part, it looks like only 3 traces :)
Make this first trace layer 0.20mm deep.
Somehow the layer thickness of "200um" is actually 0.1975mm so it counts for a complete layer.

The next layer surprised me. Now that I have 4 traces lain, the second layer runs 2 traces along the perimeter.
So I have two traces to "stick" the solid layer to... and you'd think... or hope it would just draw all the way across the part.
But no, it stops at the details within the first layer.
This is not a problem as inner traces on the first layer are also 1.68mm wide and therefore the solid print on the second layer has a shelf to tack onto.
Talk about GAP! :) But there is a reason for this. A couple as a matter of fact.

Do you hate printing thing with large surfaces because they always curl on you, or you feel you need sidewalks?
Or the opposite of not being able to release the print from LokBuild when there is a large flat area attached?

I do need to add one thing I noted quickly; your export precision settings do matter.
If any physical width in the print goes to 1.5mm anywhere (tested down to 1.6mm width), the trace count reduces from 4 to 2.

Another design tip is when infill starts.
I need to confirm this, but infill can be avoided if you stay under 7 layers.
For some reason, it always lays 4 layers on the build plate, and it finishes up with 3 layer on the top surface.
This is a nice design tip to keep in mind.
Remember, 0.1975*7=1.3825mm ...or there about will make for a solid print.
The actual print will come out to around 1.5mm when you run a generous gap as I do.

- - - - - - - - - -

2613

Texture!

- - - - - - - - - -

Ha! Put up or shut up, right?

One thing that occurred to me is that this method of recessing a face would help with ABS.
Done, yes it helps with all the usual caveats.

LokBuild with glue using 3D Solutech Joy-Pack ABS White:

2614
I've been lucky on my other LokBuild sheets but this one's been stubborn.
Repurposed glue to always have glue on the plate; just add water and let dry ... well, sort of.
This plate also has a 6" square moat around it :|


No elephant foot on the 1st layers; no curling (feel the need to knock on wood!).

2615
Just saying that curl avoidance doesn't mean stuffing your print into the build plate.


The treatment is the same as PLA. All the stringy lines -are- attached :p

2616

This kind of treatment could be used on larger rectangular surfaces to relieve some of the thermal stress.
A kind of millennial wicker :p

Not to mention much easier removal of the print from the build plate!

4 out of 5 for 3D Solutech ABS joy-pack refills have been excellent!
Actually, if you wanted to find them, they are Joy-Packs on Amazon.

(not spamming.... just sharing!)

I've got a question into them to find out if the formulation is any different from their 1.75mm reels.

- - - - - - - - - -

Time to put a caveat on the previous posts...
Learned something new though.

Ever notice that the infill on the first layer is sometimes pulled far away from the first 2 outer traces?
There is a reason, and it affects the above posts.

Quick narrative is that straight walls (upward) along the side (Z) will follow the rules and guidelines outlined above.

If the part has a taper inward right from the get-go, the above method of "stick relief" or "texturizing" won't work.
When it comes to the second layer, the offset inward of the fill traces do not get staked to the first 4 traces created by the first layer.
This will require more experiments to understand the slicer's behavior.

If you are following where this discussion has been going, this will make more sense.
But if you find yourself some day needing this information, of course I will clarify if I can.

I've had this full 1kg spool of Inland yellow ABS for quite some time.
After the first print, I realized this is pure junk.
It popped and spit nearly every inch of filament it laid down.
Prints were simply unusable.

Yesterday I tried "drying" it in the oven.
I had it backing between 85 to 107 degrees C (not very controllable!) for nearly 5 hours.

I printed a few things with the backed material. Pops are still there but greatly reduced.
The print is stronger! But still not right.

Lesson learned; you can help poor filament, but you might not be able to correct it.

- - - - - - - - - -

Today I got to test the "live cartridge refill" in the middle of a print.

This is using the fitting-less solution on a KISS cartridge.
I ran the previous filament to within inches of the filament mechanism.
Paused the printer and removed the hot-end connection being careful not to trigger the "head present switch".

The printer stayed in pause mode while I was rebuilding the cartridge.

Mated the cartridge back to the printer and sure enough, the print continued without issues.

Quick note: the M6 version of the new KISS cartridges is a little harder to remove only in the fact that the grippers are still in place.
They may rasp the tubing which is fine (never going to release this tubing!) but the twisting of the nut is not quite as simple as a loosely spinning nut.
Not impossible and certainly not a show stopper. Just a side-note.

And to be sure, the PLA printed nozzle set and the KISS fitting-less solution just ran a completely full stock cartridge with 3D Solutech "Pig-Pink" filament (my name for it).

I am now convinced we have a means to "restore" a stock PLA cartridge with minimal effort and expense.

ABS is to be determined. I will test that theory soon now that I have some clear ABS from 3D Solutech.

Just for fun.
The upper points are the part that rests on the little foam pads on the printer.
Chip pocket is still there. All for the price of an M5 tap.

Now you'd think that you can put the stock spool on there and be happy, right?
Not so fast. This is missing the despooler route (capture of the feed tube).
But for external spools, yep, this is way simple.

Well desktop/semipro lasers (those you could run at home) can (usually) only cut acrylic, wood and paper/cardboard. So the list is quite short for the "healthy" side. Any plastic that contains chlorine (like PVC/Vinyl) is unhealthy for both the owner and the machine.

Interesting new finding:

I've been busy converting a lot of old hub parts to B2B cartridges.
Today I posted the newer style cartridge cover modification to maintain aesthetics and functionality.
And I will confirm here that a scroll saw makes short work of this.
Of course, the marking, cutting, filing and sanding can be as quick as 5 minutes (more time to clean up than the actual work!),
My attempts at near perfection is around 1 hours per cover.
With the window cleared out, you will also find that taking the cartridge apart is quite simple as long as you have a tool to unclip the center tabs.

However, this post is about the really badly damaged caterpillar track covered tubing.
It also means you need to have that exactly 2mm diameter rod of some kind.

What I learned yesterday is in keeping what I know about Teflon (PTFE).
I had a piece of old stock tubing laying around. This is one where a filament will bunch up if it gets too wide from pumping back and forth.
This particular piece clearly showed deformation when the exoskeleton was added to the tubing.
The 6" long 2mm drill rod that I have didn't want to go in at all. After a little convincing, the ID opened up to the original size and the rod was a normal snug fit.
However, the outside remained deformed misshaping the tube and little fuzzies on the surface.

Remember that ABS core for the B2B nozzle? Remember I said it wants a 2.8mm drill run through it?
Well, once I got the core to be the right size to snugly fit the tubing, I could use the core to "restore" the Teflon tubing to its original conditions (okay, 95+% maybe).
I put the rod in the tube and slid the core over the tube with all due caution.
After a while, you will notice that the tube begins to restore its original "extruded" condition.

This means a whole lot more usable tubing is actually available per cartridge.

This is the recovered piece from near the stock hot-end. The threaded parts was obviously cut and discarded.

2704

...this is quite consistent from what I know about Teflon. It only changes shape under certain conditions. Basically, I am restoring it to its natural relaxed state.
For this tubing, its natural relaxed state is as a 2mm ID, 2.8mm OD tube that was deformed when the nylon over-mold was added.

This is one of those "...forgotten more than you will ever know..." category. Also known as CRS, of course.
When I went to look for some spare 2mm rod online, I ran across a "tool" I used in the early efforts about a year ago.

- - - - - - - - - -

Interesting... I am trying to print up a series B2B parts and ran into something strange.

I ran 6 of the hot-end tube nuts in ABS all in a line across the back of the plate.
Not one mated properly with ABS housing I printed!
Then I printed the very same part as a single with its cooling tower...
Worked perfectly!

Now I am baking up some more bright yellow ABS pasta in the stove.
I am going to retry the ABS orange after 4 hours in the stove last night.

Here is what I am figuring with baking ABS:
Remember how rewinding filament onto a stock 3DS spool would stress the filament inducing stress cracks?
I even had a supplier tell me that doing such would void -their- warranty?
Well, for the Inland Yellow ABS, I am going to try winding this on the 3DS spool and then baking it hoping to relax the filament while drying.
Last time I reversed that process by baking first and winding after. But the filament obviously cooled too quickly to be effective.

Only in America! Okay, only at Harbor Freight...

All this time I wanted to make sure I got nice opaque filament similar to the stock 3DS material.

3D Solutech has come closest to date.

Good ABS vs. bad ABS...

2723

On top is the clear filament from 3D Solutech which they replaced promptly.
I wanted to see how this would look next to some quality ABS.
Care to guess what brand the orange is?

I put the clear filament under a microscope and didn't see anything obvious.
All the little missing zones are plosive pops.

Now we all consider these plosive develop over time as moisture is drawn into the plastic (yes, plastic is normally rated for water adsorption in percent).
I considered this too. Another consideration was that a small cavity can merge with others creating larger voids with humidity. This is only hypothesis.

Now consider this; The last image i posted of this problem was with the Inland yellow ABS. I baked a pound of the Inland and started printing with it.
It made zero difference even though I baked it at 150*F for nearly 6 hours and printed as soon as it was back to room temperature.
Then I compared it with unbaked filament. They were exactly the same!
Much better than the clear sample above, but holes from plosive air or moisture were still prevalent.
Yes, it could be a simple air puff if the ABS was aerated at any point in the manufacturing process.

Now to eliminate all the possible variations in the experiment, I used the same nozzle using the B2B bowden solution for easy filament changes.
The cartridge was the same cartridge with an ABS chip.
The bowden tube is the same for all the tests too.
And the same printer, of course.
So the only thing that changed was the filament and the way is was fed into the cartridge.
Yellow baked was on a 3DS spool.
Orange (old) was on a 3DS spool.
Yellow unbaked was a dozen loops outside the cartridge, old filament spool on rollers.
Clear was 10 loops from the spool hanging free outside the cartridge.

For a change of pace, care to try out this little benchmark toy?

2759

I printed this with the 3D Solutech white PLA just to see how it would do.

Once you break this in, which doesn't take more than a minute, the nut will spin right off the screw part with just a twist of the fingers.
It really is hard to put down. I am impressed!

Today I finally figured out what the Cube 3 is doing when it slows down...

It has something to do with a G-code setting for "minimum layer time".
Apparently, the Cube 3 deals with this two ways;
1) It slows the print velocity...
2) It parks and rests for a period.

Not sure where the 3DS slicer makes the distinction, but now it makes sense.

This is where the Cube Print 4.03 app differs from M$ 3D Builder app.
3D builder knows to slow down on Marvin's loop when printing in ABS.
Cube Print 4.03 just makes a mess of the loop.

This comment applies to printing 1 marvin by itself.
I am suggesting 3D Builder has better thermal management.


I also found the "alternate" raft... literally, raft vs. skirt.
It is an option that showed up in the decoded .cube3 file.
Neither app lets you take control over this setting.

- - - - - - - - - -

I finally feel vindicated about the test print provided by 3D Systems.
Yes, it is a 3D System sliced object...

...back from V1.00 with a minimum FW version of 0.00!

And the notable difference that I've argued more than once...

I've stated in the past that the test print does a sparse fill as compared to current prints on the build plate.
I've tested and proven this to myself over and over again.

Today I finally figured out why.

The two test prints in the F/W drive (the internal SD) has both test prints in a "FT" folder.
When I decompiled the test prints (welcome.cube3) it shows a first layer at 0.38mm
If you look at any current print file, it is set to 0.25mm.

This explains SO MUCH!

And on another note, NONE OF THE KANJI CHARACTERS ARE THERE! In neither file!

This is just further proof that the Kanji data is just the image on the screen.

Here's the header data for both:

- This is really strange, Alex... When I pasted these from Excel, all my M601 Pn S60 F5 changed to S-60! Dangerous for sharing code!-

My how little things change... (http://cubify.s3.amazonaws.com/public/bfb/d100253_bfb-3000_set_up_and_operations_manual_v3-0.pdf) <<== PDF BFB-3000 manual link
Operation manual for the BFB-3000... LINK (http://cubify.s3.amazonaws.com/public/bfb/d100253_bfb-3000_operations_manual_v3.4.pdf)

I wonder if we can glean stuff from the Axon BFB generator noted in this manual.
It is obvious 3D Systems remained on a single freight train from day one of their consumer printer market.
It even has some NASA references when you dig into this printer and the code. This means there is public record regarding this printer.
We truly need to better understand the custom Mxxx codes used in the .cube() files.
I have a feeling these routines and assigned codes spawned from the Axon app and were never fully adopted by the community at large.
Yet, 3D Systems chose to maintain their legacy interpretations and continue building on them. That decision can really mess with conversion apps.
The command set is so small that the required detailed information could be covered in a few pages.

No matter what, today was a good day. Got rid of my woes with ABS on the Cube3! Resolved a nagging itch about the stiffer bowden tube on the Cube3.
In all, I owe you, John Tee! A few simple words cleared the skies. Conversion is working perfectly. Shame to loose WiFi though.

Here is some nostalgia...

Anyone know the backstory between BFB and 3DS?

When it rains it pours... and not just salt!

I took a chance on the re-listing of the two red PLA cube3 carts on ebay by making an offer.
Looks like I have 3 new cube3 carts coming my way.

I may have to do a B2B upgrade offer on one or two of these.

PETG IS UP AND RUNNING ON THE LITTLE WHITE CUBE3! Okay, color me intrigued. Sticks well to LokBuild, PETG has a nice thermal profile, and the EkoCycle slicer is gentler on the mechanics. Price to pay is a quick edit. Ouch! And I'm also going to suggest that this profile may work well with 3rd party ABS as well!

One vote for PETG being wearable...

I got to hold it for about 5 seconds before it was no longer mine :eek:

Finally designed an 18650 Li-Ion battery holder that I like.

Also works well as a 18650 cell protector.
