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

A Y overflow is that the control sent a command and expected to see a move and did not see a move.
If it indeed did move and it was not seen, it would indicate a bad position loop (encoder, cable, board, etc.).
If it did not move, could be mechanical (bearings, gib, ballscrew), motor or drive board (but I would expect a axis drive fault), or no command from control to axis drive board.
