I am working on adding power control to grbl. This will enable automated control of power to the spindle, dust collector, caution light, etc. (It can also be used to control multicolored disco lights, should a party break out in the area.)

The light controller will also double as a case for the Arduino, grbl and relays.

This is a work-in-progress. I'll be using it with my Shapeoko CNC Mill.

Bill of Materials:

  • 8 lighted switches
  • Maximum load capacity of 15 amps (1700 watts)
  • 8 three prong outlets on the rear of the unit
  • 15A resetable circuit breaker
  • 19” x 2” x 5” (482 x 51 x 127 mm)
  • 3.75 lbs. (1.7 kg)
  • 5V 8-Channel Relay interface board, and each one needs 15-20mA Driver Current
  • Equiped with high-current relay, AC250V 10A ; DC30V 10A

Connections:

  • Seeduino Analog 0..5 -> Relay Module IN1..IN6
  • Seeduino Digital 12..13 -> Relay Module IN7..IN8

Questions:

  • What gcodes should be used to control power?
