I'm thinking it's a noise problem on the step input to the driver. Probably related to power line conditions as it's very intermittent. Since the last direction for the Z axis when cutting is down, any noise on the step input big enough to trigger movement is going to result in down motion. I'll search the forum for advice on power line noise suppression.
