Motor 2 Malfunction
There is an issue with stepper motor No. 2. While motors No. 1 through No. 6 lock completely when powered on, only motor No. 2 rotates freely by about 5 degrees after the power is turned on. I would appreciate it if you could advise me on the cause and possible solution. Thank you in advance.
