I've been doing functional ABS and ASA lately and had a couple very annoying warpage spots. One was a total failure. (We won't talk about the other 3 failures that were wet out-of-the-box Bambu ASA...)
The X1C is definitely nice, but the all aluminum-and-glass side panelling has a sometimes-unwanted side effect: thermal conduction.
The aluminum sides are so conductive that they do not allow the chamber temp to go above 40C, even after a couple hours of heat soaking the build plate at 100C before starting an ABS print.
Enter: One random bath towel. doesn't look like much but just covering the three sides with a thin layer means it's good enough insulation to get the chamber up to 50C now! And the ABS parts look better than ever- every C counts.
I use a brewer's belt with my resin printer when it's cold. It has made a big difference. Keeps the printer warm without getting too hot.
Mm, heat tape with a thermostat, that does sound useful for a resin printer. I've been rolling around active chamber heating in my head for a while to hit the magical 60C and that could be one option for it.
