I really would like to ask if anybody is experiencing low clicking noise coming from the x ya axis, it's not affecting the prints or anything, I just want to make sure it's not a problem that will get worse over time. (By the the way it's not the clicking sound coming from the hotend, I have that problem from time to time and it usually fixed with a clean nozzle.)
You can try to look at the manual to look for all the screws on the axes and see if you have to tighten them. If I remember correct the gear on the engine does also have a screw.
