Hello,
I am using grbl version 0.9 to make a cnc plotter (drawing machine) with 2 steppers and 1 servo.I connect the servo correctly (5v gnd and Z+ (D11)) but when i try to use it the servo moves a little bit and everything freezes and all motors stop.Must reboot all software and hardware. Any sugestions?
There is a version of Grbl with servo support. I have not used it but it may be of use to you.
