I'm having trouble setting up Homing on my MPCNC.
I'm using Arduino Uno with CNC Shield and CNCjs as a Gcode Sender and have uploaded GRBL 1.1h
All connections are made to the CNC Shield.
GRBL codes for auto homeing are enabled, when the process starts it lowers the Z-axis and limit switch is activated but the machine does not stop.
I would remove/disconnect the drive couplers before testing homing. If you crash an axis it can cause
expensive mechanical damage. Just simulate the movements by hand-operating the limit-switches and check the motors stop.
Once you have it doing the right thing re-couple the motors and check again with hand over the e-stop switch...
