Cannot Home or move in single axis
Yesterday I dropped the PCB so that I could check the max power setting. After reassembly, the Home function no longer works and movement commands (using UGCS) are always diagonal no matter if X or Y movement is requested.
Issuing the $H command initiates a diagonal move towards the origin when it should move to the X axis home and then to the Y axis home. Activating the X axis microswitch stops the diagonal movement. Activating the Y axis microswitch restarts the diagonal movement.
I have reset the GRBL settings to the defaults.
Help would be greatly appreciated. Nigel
