Hi all! I need a high temperature (~200C) motion system for ahem reasons. I know that at those temperatures steppers tend to cook, so keeping them inside the heated chamber is out of the question. I have already considered belts, screws (lead and ball) and stainless cable. Belts will not work because they will melt. Screws do not allow for static motor mounting and stainless steel cable has slip and extreme tension. Do you guys think chains and sprockets will work? Are they precise enough? Any input is welcome.
Chain shouldn’t be a problem. The precision comes from the motors, not the link size.
You’ll need to make sure your tension system can take up the slack you’ll create at 200c though, as well as considering how you’ll deal with backlash.
Good luck!
For high temp, maybe consider a foxed nozzle in XY and only moves up in Z and the bed moves in X and Y. Like a CNC mill.
Wow, good idea. I am kind of considering going delta, but this is a good approach too. Will think on it. Cheers!
That’s how I saw glass 3D printers are made. Moving the thousands of degree head is rather complicated.
