Air Assist Power Source

Hi , how do I power up my air assist pump motor via gcode?

I think the best way if you have the black box controller is to us the 6 pin load L1 and L2 load connectors on the back and use M7/M8 commands to turn the power on to those pins. I forget what voltage the controller runs at, but I bet a buck converter will get you down to 24/12v to run the pump. This is what I was planning before I decided to use another controller.

Hi Thanks for the input, the L1 L2 though a bit tricky to insert in the gcode because of the Hilo Lo High setting. Ived tried it before with some other enhancements of my OF, but will give it a check Thanks
