Hi all,
I'm currently busy trying to figure out how to set the homing offsets for the CNC router we're building using Marlin with spindle control. It homes at (0,0,0) and then the spindle is at it's highest position in other words they are all homed at the min positions. I want to use a probe to set the height from the workpiece, that should be offset 19.45 (the height of the probe), but I want to position the spindle over the workpiece, but it doesn't want to do anything if the machine hasn't homed.
The spindle get enabled by M3, but where do I define the output pins in Marlin when the M3 code has been sent?
Any help would be greatly appreciated.
