So I am doing one of my typical production runs, cutting .080 sheet aluminum. All is going well. About 2hrs in, the machine runs the Z axis deep into the work, and I think tried to run it through the table before it physically stopped and Mach said an E stop was pressed. I was in the next room do other work. Nothing sounded bad, so it must have been a quiet death.
I tried to jog the Z axis out, but no matter which way I jog it, it wants to go further into the table. Sounds pretty nasty too. The DRO shows the Z axis moving correct according to the jog wheel.
With the machine off and I manually move the Z axis, all feels normal.
X and Y jogging work fine.
So did I fry my Z stepper? Any idea what would cause this? The GCode is fine, I have used it a number of times on production runs.

Sounds to me like your Z Axis Dir wire has come loose.

Thanks hood. That was darn close. It was the connector from the back of the control box, other side of the Gecko.
