I have all of the hardware (I think) to make this happen, but has anyone else gotten spindle control in code working with the M3?
I can find very little on the internets about this. If someone can point me in the right direction, it would be much appreciated.

You do have all the hardware to make it happen if you have our 400w spindle kit. You reflash your board with this firmware: sabercathost.com/F0u/MillRight_CNC_Model_M3_Grbl_PWM_Homing.hexUnplug the potentiometer (the adjustment knob) from the speed control board. Run a wire from the positive side of the Z+ terminal to the screw terminal labelled "PWM". Tie the "GND" back the the ground side of the Z terminal. Move your Z homing switch plug to "Sp En" on the red board. M3 is on, M5 is off, Snnnnn sets the speed, where nnnnn is the desired speed (12000 max). Derek |
