PID control uses higher frequency PWM and is superior for maintaining a stable temperature. The bed must maintain a stable temperature for TEMP_BED_RESIDENCY_TIME before M109 will return success and start the print. Tune what “stable” means using TEMP_BED_HYSTERESIS and TEMP_BED_WINDOW. Adjust the relevant settings to your specifications for use with SWITCHING_TOOLHEAD, PARKING_EXTRUDER or MAGNETIC_PARKING_EXTRUDER. Adjust […]
