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.

check if the screws locking the coupling are tightened. If the screws are loose, it may cause slippage.
Thank you for your response.
We have already checked the coupler.
As for the motor, it was ordered through a supplier around December 25th.
We have attached a video showing the issue, so we would appreciate it if you could take a look.
Can you check the coupler between the motor and the gearbox? There is a small black plastic cap on the side of the gearbox. If you remove the cap you can access the coupler and tighten with a hex key wrench. This has been a common issue in the past. I have contacted Stepperonline and this should have been addressed so they come tightened. Please let me know how long ago you purchased your motors kit.
