Re: Motor problems
With a worm gear, the arm should never backdrive like that. If anything, the motor would just stall out when trying to lift. It sounds like something (chain, set screw, worm gear itself?) is not fully engaged and/or is experience so much torque that it slips. What is the sprocket ratio between the motor output and the arm itself?
