Tried some additional things. Turned off the G100. Tried to get into config>motor tuning. No dice. Still get the same g100 is active do you want to flash to it message window. If I select yes mach crashes. If I select no nothing happens. I did get all of the inputs, limits, estop etc working. Motor tuning remains elusive. Anybody know how to turn off the g100 mode and get back to the standard serial port mode. Maybe I can access motor tuning then and flash it to the g100 once I am back in g100 mode. A bit cumbersome, but I would settle for it now to get things running.
