You mean propellers?
Pretty damn well, none have disintegrated so far and mostly the smaller ones stay intact when bumping into something while spinning, it takes a bit of effort to break them, and that is mostly due to printing direction.
Also i do not use PLA, ABS, HIPS, PETG, and lately PA6 Nylon.
The main issue are sanding them properly will improve efficiency a lot, and balancing them is a must sometimes.
Give it a try, you will be surprised how good they can be, just keep layer line longitudinally.

It could be done. It's probably how I would do it if I had to control an injection moulding machine, but only because I already know how to use LinuxCNC.
(when your only tool is a hammer....)

Getting temperature into LinuxCNC HAL is not the easiest thing. One option is:

First such machine i fixed was back in 1990 !!!
They are complicated machines, but all are made from simple parts, so look at it as separate parts, makes it much easier.
The main hurdle with retrofitting such machines is the logic and interlocks, writing down whatever you already know will help a lot during programing.

but if there's no new tutorials out there to guide newbs, then i might as well not waste my time and just install windows.


Makes me wonder why we bother maintaining about 1500 pages of written documentation:
