The effort involved in cloning electronics is a world of difference from the effort involved in cloning a kit.

Actively cooling that setup without any sort of thermal break is going to be a battle between the hotend and the cooling fan.

If you are actively cooling the cold end then using something with low thermal conductivity like PEEK might make less sense. I use aluminum as my cold end and a 40mm video card fan is plenty powerful enough to keep it cool to the touch.

Wait a minute. You're saying that nobody bought your robot because its source was available ahead of time?

The radius of the flying carriage also factors into the horizontal reach. This is easiest to visualize when one set of rods is at the low extreme and are near horizontal. The flying carriage effectively increases the rod length by its radius.

Deep Cool Z3 has an advertised temperature rating up to 300C.
The container is pretty convenient for reuse too.

Using the violence of the state to enforce a physical property ownership concept between apes is one thing, but using the violence of the state to prevent an ape from physically implementing its own ideas is another.

That's a super interesting concept Martin. I could envision a more simplified version that might be useful. If you imagine an offset 1/2 the layer height at the end of the nozzle as a pivot it might be useful to orient the nozzle about that pivot so that you get better stacking with less overhang. A section of a thread is really a capsule and not a circle, but it might work out ok in practice.

If the CAD files are released opensource by the author then another community member can release the files in STL or whatever. If the files are originally released only as STL then you're stuck at STL until someone reverse engineers the files to something else.
Release of files is author's prerogative. Whinging about an opensource author's work as "not being good enough opensource" only discoura

I've been running belt teeth over a bearing lately and it seems to work out just fine even though it doesn't look like it should.

Oh geez Rich. Your vase progression gave me an idea.. Stacking dolls! Print in upper and lower parts and the image could be embossed or a lithophane.
What do you think? Robots or owls or classic?

Please do join in. Showing what's possible now is what raises the future quality bar for everyone.

20mm tall. 0.083mm layers. 0.65mm thread width. 180C. No fan. Two at a time.
I really need to make a smaller nozzle.

20% squirrel. 0.17mm layers. 0.65 thread width. 0.5ish nozzle. 190C (I forgot to lower the temps doh) 30mm/s. No fans. 4 at a time.
I had no idea that the zoom buttons on my phone were actually useful. I figured they were just a lame digital zoom post-process, but they actually do zoom. Nice.

Here's that rook I printed ages ago. Entire spiral is intact. Next to it is my favorite latest print.. A 40x40x40 one perimeter walled box!
Since that box is so sweet here's it straight off the printer. Check out that sexy seam!

Your experience with a nozzle nipple requiring less extrusion pressure is the opposite of my experience. If I am targeting a less than 2mm exit length then a nipple ends up being a significant fraction of that.

Not-wild guess.. Your other printers all have screws for Z?

The Printxel has a 400g X carriage and probably half that for Y with a 140x140mm empty bed. Marlin defaults lately. Double pulley (for torque) setup on 1400g-cm NEMA14's. It's not a fast printer at all, but speed is limited by the hotend and not the mechanics.
