Hi,
I'm still running an earlier plugin but looking at the code associated with the 'Go To Work Zero' I found:
GoToWorkZero()
--local inst = mc.mcGetInstance()
--mc.mcCntlMdiExecute(inst, "G00 G53 Z0\nG00 X0 Y0 A0\nG00 Z0")
Note that it calls for movement of the A axis. As my machine is not fitted with an A axis and therefore no 'Motor 3' is defined or enabled I would expect an error
if I clicked this button. It sounds rather like your machine has the same problem, either alter the code so that it doesn't attempt to move an undefined axis or
define the A axis but not equip it.
