Is chain driven CoreXY possible? (lemmy.one)

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.

I’m not real familiar with it, but you might look for some chain with a width wider than one link. Seems like that would provide you behavior more similar to belts. It seems McMaster sells double link width, but there may be other sources of finer/wider variations.

I have seen double link chains. They might provide more rigidity but I am not certain. Thanks for your input, it's greatly appreciated.
