I've recently bought a 3018 Pro, utilising a clone of the Cronos Maker board. I'm doing PCB milling / drilling and the supplied 775 DC motor is far too slow. I'm replacing the motor with a 3-phase motor capable of around 30 000RPM along with a speed controller. I want to take a PWM signal to generate a speed control signal for the speed controller, but the PWM signal on the 3 pin laser connector doesn't seem to be present. Do I need to set a configuration setting to enable the PWM signal?
