I've had my M200 for about 3 months and when I went to begin a print the feed motor gear just jiggles back and forth without revolving? Anyone had this happen? Is my motor bad? I verified that the set screw was tight. When not attempting to load gear doesn't move at all.
This error most probably results from a broken ribbon cable!
I will happily buy your lunch. I inspected the connections and sure enough my green wire had come loose from the connector to the motor. I soldered it back and ran continuity tests, reassembled and am back printing. THANK YOU!
