New clicking sound coming from the stepper motors

[jgowing 0]

I have a new Ultimaker 2 with 50 hours usage.

It has recently started making a clicking noise, whilst printing, which I think may be coming from one of the stepper motors.

I have watched and listened to the printer carefully and I believe it is coming from the RHS stepper motor (facing the front of the machine). I think this is the motor that controls the left/right movement of the print head.

The clicking has an average frequency of about 1 second with 50mm/sec print speed. So I am guessing the clicking happens with approximately 50mm of movement. It seems to happen in the middle of the X/Y position of the printing space. This could indicate or reflect the position where the printer has most naturally already seen the most usage and hence wear.

Has anyone else seen this issue? Does it develop into something more serious? Is this an indication of a defective component or something that is wearing out early (component infant mortality).

Try to slide the shafts 1 by one. You may find that one of the pulleys has moved slightly which allows the shaft to slide.

The click can come from the spacers hitting the bearing.

Making a video or sound clip could also help determine the problem.
