Use Simplify3D with a Cube 3

[juansalvo94]

Hi Tommy. The print file is this: https://www.thingiverse.com/thing:2253091

Dougk12, I even tryed with the cubepro encoder, and then renaming the file to cube3... Didn't notice any difference. So we can assume that this two encoders have the same result.

None of the prints have warping on the first layer, but they have warping on the last solid layer.

Will try with the quality guide on S3D website. Thanks!

Sorry Juan, I meant the final print file submitted to the printer. I wanted to look through the BFB to see how temperatures are treated.

Oh, thats ok. I can't attacht the file to the forum. I've put it in the shared folder: https://drive.google.com/drive/folde...K5?usp=sharing

Each file has the temperature in the name in celsius.

I am seeing temperature changes throughout the file and I am seeing extruder 2 bias temperatures. M104 calls without a P1 appended are 'wait for temp' if I recall correctly, so each change should cause a pause for the temperature to stabilize.

To check my own sanity, I created a better "temp wizard" for 210-190C but again.... I don't see changes in the quality of the print from top to bottom. I trust that the commands are there but I suspect the Cube 3 is simply ignoring all but the layer 1 temp command. Based on the quality of the raft, it appears to be printing at the layer 1-9 temp of 210C (as it should) but no changes.

Can others confirm that when printed there is no indication of temp change and the gcode for temp changes are correct? Perhaps I can replace the temp control gcode and then re-test?

[TommyDee]

Dougk12 - all the temp changes are there in the file; 1*C at a time. I might recommend limiting the range to 5*C steps. Seems that is how Cubify manages temperatures so as not to upset the works in case it ignore "invalid" values or somehow ignores all values after the first instance of an invalid value. These would be quirks within the code but they also have control over the expected input. Just a tip. Untested and unproven. Provable, nevertheless.

Why is your starting Z-value 0.656? After a typical Cube3 gap procedure, somewhere between 0.22-0.25 is the normal starting gap within the print file. Just an observation. This could affect how you dial in the first layer. I suggest using an initial offset of 0.25 and tune layer one extrusion rate and head velocity based on that smaller gap. Cubify uses 20*C extra on PLA for the first layer and a slower velocity. This all in an attempt to get good adhesion on their substandard build surface. Feel free to tweak from there for these newer build surfaces

I'm going to suggest your filament didn't care about a 20*C temp change. It was tuned well enough for the full range. I would say that Cube3 native is very forgiving with most generic PLA's. What I would be looking for is a continuous surface in Z and changing temperature 5*C every 10 layers from 190*C [since that works] to 235*C [since Cube3 does that anyway]. What you will see change is twofold; 1) look for -sheen-; there will be a glossy zone and a matte zone. That is the proper range. & 2) 'Plosions - An audiophile term for bursts of auditory energy. In the case of the Cube3, the wild retractions it does with ABS causes 3rd party filament to take in air. The temperature of the Cube3 ABS slicer is 10*C to high for most 3rd party ABS. So the air is mixed into the very hot melt and it comes out of the nozzle end just belches a little hole in the trace being lain down. You can hear it. They are annoying little pops throughout the print. PLA is not prone to this, but if you hear them or see these "plosive remnants, you are running the filament too hot and you should visit you retraction and destringing settings.

Are you using BuddyBu's editor yet? Highly recommended. it shows me all the temps you added.

[dougk12]

Very good info! Now you have me looking at gcode .

Good news, the temp adjustment gcode commands are not ignored or malformed, you just need a better test! Here is a better temp wizard print for PLA (190-235) and I confirmed a noticeable change from the bottom to the top. The bottom is 190C with +5C every 4mm (include the raft when measuring). For me, the quality deteriorates around 210C and gets worse as it progresses up.

If this is helpful and you'd like something similar, just shoot me a DM.

I'm pretty sure I had the temperature adjustment working correctly. You can use the cubify software to watch print head temperature and see that it changes throughout the print if I remember correctly. If you find some changes you think should be made to the profile I would love to see them. I would like this to be as streamlined as possible for newer people to jump into.

[TommyDee]

@Sofa_Kingdom - Would you have any use for the original settings that Cube3 uses for the various slicer materials? They can all be made readable. I've done some spreadsheet work to discern their differences.

The more material I throw at the Cube3 the more impressed I am with their implementation. I am particularly impressed with the Ekocycle slicer on PETG.

If you find the config file [.xml] and you start looking into them, they are just repeated recipes depending on menu choice. Their is only a handful of actual useful datapoints to look for that repeat for each setting. For instance there is "ABS at 70um" and "PLA at 200um" as the first level sub-category. Any of the current decoders will make these config files readable.
