Totaly unresponsive, The hour glass pops up as the pointer and nothing can be clicked, estop does nothing. Its as if its lost comm with the smooth stepper and its waiting .
Forcing Mach to close leaves the spindle turning and coolant on , juast as it was when the program locks. I can then walk to the back of the machine and unplug the SS and the spindle and coolant will stop.
After it locks and I close mach I have to unplug and replug the SS board before Mach will connect with it again.
I have moved all the plugins other than SS to a temp folder , will run it the rest of the day and see what happens
