OK, I was just told that it is important not to hook up the CNC mill before you install Mach. So, I was told to "uninstall" Mach, disconnect the CNC mill, then Install Mach, then reboot, then reconnect the CNC mill, then when you start Mach, ideally the STATUS BAR should say "Driver initiallized". And everything should work.
So we tried this methodology. Still NOTHING. The wireless hand-held controller communicates fine with the MACH control screen, but the CNC is still not moving.
Does this provide any further insight?
