I made my own Rotary much like many on the forum, I have been using it a lot and no issues. I am working on 3 sets of chess pieces and about 35 pieces in I was vacuuming up the chips with a shop vacuum and was close to the rotary and it quit turning, I did not hear or see static but feel like it was the culprit, did a power cycle and all was good again, did the same thing yesterday and the same thing happened, power cycle and all is good, today when I did it I power cycled it and now it has changed. Before when machining the chess pieces the rotary would turn 360 and reverse direction for the next cut, now it continues to turn in the same direction all the time, when it finishes a pass it spins several rotations, not sure what direction and starts the next pass.
Same G Code same everything except the rotations are weird.
Any suggestions why this could be doing this, It still makes the parts fine just weird.
Thanks, Pat
I don’t have a rotary; but when I worked for Delphi Automotive, we used to test our radios with static discharge on each pin of our connectors. I’m also not an electrical engineer; but, it was my understanding (and observation) that if the circuits weren’t properly shielded the static discharges (over a few cycles of testing) would “round off” the digital signal and cause problem like this going forward on that circuit.
I suppose that could be the problem.
If this is the case how do I correct it?

paulc can you run a ground from the rotary to the frame of the cnc? Just a thought.
I can do that I suppose it might stop it from happening again , but right now the Rotary will only move in one direction even in jogging mode, one direction it turns the other it does not but the DRO on the display does count like it is moving.

Pat I’m sorry I don’t have an answer for you. I would suggest reaching out to the manufacturer of your rotary for assistance.
Thanks, but in reality I am the manufacturer as I pieced together all the parts to make it.
Pretty sure I have a loose wire or I fried something the the stepper diver, just have to keep digging.
Thanks, Pat
@Pezwoodworks Good luck with that
I figured it out, the motor or more specifically the driver was bad, replace the motor/driver with one left over and all works as it should again, Lesson learned do not vacuum the area when the machine is running, I believe static fried some electronics in the driver, amazing it still worked at all.
Pat
Glad you got it figured out
Thanks for sharing your experience!
