Solutions below the question:
I am try to print ASA. I have a top cover. I have tried to set the print bed to 100C but after a few minutes it turns itself after a 5 min. I tried the same from Orcaslicer and the same result. I also set cavity fan to 25% to move the air around and that stays on.
Any solution to the heat bed auto turn off?
Solution #1 No changes
You can start the print and as soon as it is preheating press the “pause” button which allows the heater to bring the chamber up to any temperature you want.
Solution #2 Change to printer.cfg
I found this solution by Nicholas Schmidgall on facebook.
EDIT: Found it! Line 1314 in printer.cfg Change timeout from 600sec to any amount you want. I set mine to 1800 which is 1800. So you can set the heat bed to 100C manually but the 5min timeout is extended to what you set.
Solution#3 add to your filament gcode section
Inside the ASA profile I put this gcode to make the bed temperature to 100C and wait 30min.
M140 S100 ; Set bed temperature to 100C and continue immediately
M190 S100 ; Wait for bed to reach 100C before moving to next line
G4 S1800 ; Dwell (wait/hold) for 1800 seconds (30 minutes).
