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!

Alright. That is great to hear. Already thought of the slack, but the backlash might be a problem. I'll figure something out. Cheers!
