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!
Not an engineer, but I guess it could work given a fine enough chain and precise enough gears. Lubrication at those temperatures might be a pain though?
I have found a lot of grease brands with the operating temperature well above 200C. But yeah, the problem is always with precision. I guess I need to look for a strong enough fine chain now. Thanks for the help.
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.
You could water cool your steppers with an external pump/coolant refrigerator
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.
For everyhting 3D printing related.
Please be excellent to each other :)
