X/Y/Z axis doesn't move
1. Check the port to see if the connection is successful
2. After the port is connected, use the mobile phone to manually control the XYZ axis to see if it can operate normally. If there is a stuttering, you can nudge with your hand to see if it improves.
3. If the above steps are carried out, the stuttering phenomenon of XYZ still does not improve, we need to send an email to the email@example.com for consultation, and attach a shooting video of the machine problem (the footage of the entire machine running)
