Dear All,
I'm looking into building drilling and milling head for my Prusa and need to control a DC motor. I'm using Gen7 electronics and Teacup firmware for printing and my initial prototype of the head is driving the motor using heater2 (bed). I'm just setting bed temperature to anything non-zero and off it goes with 12V raw power.
The problem is that I can't control the speed of the motor.
This page gives an indication that Teacup firmware has 'untested' DC motor control functionality. However, there's nothing about in on Teacup Firmware wiki page, nor does Google find anything interesting.
So two questions for the community:
1) What is 'DC motor control' in Teacup firmware and how to put it into use? (Hey, I volunteer for testing!)
2) Is it possible to somehow use the function with Gen7 electronics without major modification?
