It is itching...
I think I found a couple of free ballscrews+fixed bearings, just have to pick them up and check out their condition. I know where to get some lineair rail. And I know a guy with a CNC plasmacutter who is willing to return me a favor.
Replace all plastic parts on the screws and rails with metal, and they should easily be capable of handling 120-200 degrees C environment; it mainly depends on the grease used. A chassis entirely made from plasma cut and welded sheet steel is resistant too, and the sheet steel can be heated with some silicone heaters to heat the entire chamber without disturbing airflow. Motors can be shrouded and liquid cooled. And two Hemera-like extruders in an IDEX configuration can be duplicated in full metal with liquid cooling. Due to everything being steel the structure distortion due to heat should be minimal.
The itch, ooooh, the itch...

Looks great. Gates belts are rated to 80 C. So are most linear motion components, so it's a good match for a heated chamber.

Hi!
I know this is old but may i ask a few questions?
first of all how did you get your rails to handle 150! genuine stuff only handle 100c max, and cloned do 85-100 depending on where you get it afaik.how much did this cost?
what's the difference between your ambient temperature and part temperature with the IR light blasting on it. what advantages does it have over just regular air? does the radiation also heat up your printed parts?
have you had any luck with getting PC to survive there? I was thinking of covering my printed parts in aluminum foil so radiation bounces off. leaving my parts cool enough in theory. -

[...]These rails are rated for 150 C.
