Those are the sounds as the laser print head moves from left to right on it’s belt. The unit has only been used a handfull of times, and it’s as if the guidewheel attached to the belt that controls the print head’s left-right motion is running over a speed bump 4-5 times per movement.
I agree with @ca_worth that you probably have a cracked wheel on the gantry plate the laser head rides on. you can remove the plate by following the removal and install steps here but ignore the parts about cleaning the fan. also inspect the pulleys that drive the belt on the under side of the gantry.
Hello @mrodriquenz - sorry to hear that you’ve found a cracked wheel, but as others have said thankfully this is a relatively easy fix! I’m going to shoot you a follow up email to collect some information so that we can get a replacement order started for you.
I’ll go ahead and close this topic and we can finish up via that email.
