Y axis Makes a clicking sound

Have had the 5 pro 4x4 up and running for a couple weeks. Yesturday a clicking sound started coming from the y right axis (just when its moving). I checked all screws all are tight. figure I would post here 1st to see if anyone else experience this before i contact support.

Hi mailman I just assembled my shepeoko 5 pro 4x4 and Y Axis on the left side is making clicking sound. have you been able to figure out what was the problem?

yes . mine was on the right side rear stepper motor had th be shimmed out. I loosened the 4 bolts and put a piece of paper folded once on each side (just a 2 inch square piece) and the sound is no more but i check after every use to make sure the bolts are still tight.

Good luck hope it works for you. Let me know.

Thanks for the answer. Just how did you figure out what was the problem? How will I know that the engine is shimmed out just a little bit? Thanks for help.

I shut down power to unit and had a friend move the gantry fwd and back by hand i could hear where the click was coming from. And because it made the sound without power on knew it had to be mechinal and not electrical. We put the paper shims in and moved it by hand again and the noise was gone, turned on power jogged it around and same no more clicking.
