Motor jumping teeth..?

Interesting thing thing here. Haven’t had an issue until yesterday where my Maslow is jumping teeth mostly during an upwards motion while going counter clockwise just to the right of center on the machine.

Seem to be in the right motor. I was watching it and didn’t see anything obvious. I’ve been testing the brick holder seems easy enough for a test. You can see what happens after it jumped.


That does look like the right motor may have jumped a tooth on a ‘pull stroke’. This might be caused by the chain not being parallel to the work surface, or by the motor mount having pivoted leaving the sprocket no longer in line with the chain.
