I'm using 1.0 of the firmware hack. Yes I can use pla or abs on either side.

Just to confirm the magnets.
I just received some 3/4" x 1/10" N42 Neodymium magnets.
Promptly busted one new one and one of the originals. Fortunately, they all seem to be identical.

This is the eBay listing I got them from. The supplier is a USA supplier.

HELP!!!

I need to know how to best remove acrylic adhesive completely.

Attachment 1696

Magnets are 18.98mm x 2.35mm

Pockets are 19.4mm on 64mm center; 2.65mm deep.
Pattern centered on an overall 170mm x 170mm; corner radii ~R3mm.

Doing a 70um print to see how bad it is.

And tomorrow new supplies are coming.

What's everyone else up to!

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.

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.

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.

Okay, the hack is failing me!
Yesterday a print stopped extruding...
I removed the cartridge and put it aside in disgust...

Later in the night I looked at it to unclog it...
Sure enough, it was empty!

Which was the issue then?

[Mythandar]

He ran out of filament 😁

ROTFL xD xD xD

Finally, my army is complete!

About 50 hours of printing with the Hatcbox filament.

And 50 to go
