My machine was Boss 10 and I upgraded to all the hardware and software changes EMI offers.
The machine has been flawless for few years.
Running a job today, I was on the last part, y axis in middle of table and I got a +Y Overflow.
Machine check ok
Drives enable
Z will home and then machine shuts down with Y overflow.
I have no clue.

Needs some direction.
Thanks
