I am running my printer on a Mega/RAMPS. Currently I have my power supply set at 12V but I am finding that at high speeds the steppers are sometimes skipping. I want to set my power supply voltage higher (maybe 24V) but in order to avoid burning out the extruder heater I want to set the heater PWM to 50%. What setting in the config will allow me to do that? Is it the PDM_FOR_EXTRUDER? EXT0_PID_INTEGRAL_DRIVE_MAX? EXT0_PID_MAX?
