grbl spindle & cooling control V2

By | 13. August 2015

Updated the hardware to a leonardo and an spi color lcd:

The controller:

  • measures spindle rpm
  • uses closed loop control to drive the motor
  • rpm sense via reflective IR sensor
  • outputs ESC PWM signal
  • displays: cooling, rpm set & measured, direction, tool changer, selected tool, control level and two lines of message
  • manual override for spindle on/off and rpm via turn/push knob
