So I recently switched from klipper to marlin to do some laser engraving as klipper doesn't support rapid M106 commands.
After my job was done, I figured I'd do some tests with Marlin before flashing my old firmware back. I noticed that once my part cooling fan kicks on it cools the nozzle and triggers a thermal runaway error.
The short-term solution was to just limit the fan speed and continue on with my life. However, I've never had issues maintaining temp at full power with Klipper, yet I seem to with Marlin.
Does anyone have any advice on how to improve the heater so I don't have to gimp my fan speed?
