I've done a reinstallation of Mach3 on a mill and am slowly getting everything back to an operational condition (and when I'm done I've got to save the settings so I don't have to go through this again). Anyway, I can manually jog the x,y,z axes using the buttons on the jog tab menu and the x,z work with the keyboard arrow keys, but the z doesn't respond to the +,- keys. In every other way, the z seems to respond find. Any ideas?
Thanks, Glenn
