I'm out of town for a week but will investigate this more when I return.
I need to read up on the Mach3 options for homing/limits options as I don't really understand what each option does. I messed around with them and got the error to go away but haven't figured out how to get the table limits entered (mine homes to upper right).
It started doing strange things, like jog commands in either direction would only jog towards the home switches.
When I get back I'll read up more on the options, especially reversed and home negative as these seem to have a correlation to each other. I'll do some testing and take notes.
