The mill has just started a new job and as I turned my back, I heard an awful clunk and bang. My VMC15 has just dropped my new tool holder onto two vises below it. I didn't see exactly what happened but I am assuming it over travel the Z and missed the tool changer umbrella.
The message on the screen read, "Z Axis Fault Error #16 Resolver Fault"
I looked up the error in the manual and check all the fuses it referred to, F23, F24, F27 and F28. All fine.
Also tried to jog the axis according to the screen then CS, but the error remains.
Some one told me to check the resolver coils with an ohm meter and that checked out.
I also posted a pic of the 1010 board with a flashing red LED (in yellow circle)
Not sure at this point what has failed.
