I don’t think this is a software error. That X stepper motor seems unhappy. You said you can move it freely by hand (when the machine is off)? No chance the belt is loose or slipping or something like that?
I suspect once Support gets to this ticket, they can look at your machine logs and get a lot more information. In the meantime, this is just guesswork. I’m not a mechanical engineer, but I’m a reasonably competent troubleshooter, and I think I can make a list of what has to happen in order for the head to move left and right, then try to rule stuff out:
- Software decides to move it
- Control instructions make it to the stepper motor
- The motor produces torque
- The torque is transferred to linear motion of the carriage
- The carriage is able to move
I see no reason to believe #1 is a problem, especially since in the first video you can see and hear it trying to move. In the second one, it’s harder to tell because the Y movement is covering it up, but I suspect it’s also trying to move in X at the same time… normally this is a diagonal move, but it ends up just inching forward. I also have no reason to believe #5 is a problem if you can move it by hand. So what can it be? #2 could be caused by a bad cable or loose connection. #3 could be caused by a dying motor or power problem. #4 could be a problem with a belt or the little gear on the motor.
