I have seen other GRBL controllers with external displays and X Y Z control buttons. Anyone know if it is possible to interface one of these to the Spark Concepts CNC xPRO V4 Controller?
I think you can interface one of the game pad style controllers to some of the control software. Like bCNC, I think.
It works with Estlcam as well. An Xbox controller is what I use to jog the machine around. Estlcam works with the Xpro since it is arduino based.
