Well ... today at the end of grooving a 1.67 we heard the grooving wheel/mill bit spinning like mad despite the rest of the process being finished and blinking at us like it alway does. From the moment the power is flipped on that motor is going full tilt! I can unplug it via the board (first image) or at the motor (second) and it stops but nothing else I've tinkered with in the menu and settings has any effect. I can rotate the assembly in and out of position and all other functions seem to be on point.
It's a long shot, I know, but do any of you fellow OptiBoarders have any advice or help?
