My Zortrax made some very subtle clicking noises when doing certain moves from day one but over time it got louder and louder. Yesterday it got so pronounced that I could not ignore it anymore and started investigating. The clicking comes on x-axis moves with a bit more sudden direction changes. After a lot of searching I found the back/ upper/left rod bearing having a lot of play… You just have to move the rod a little and it clicks/rattles loudly. See video. I checked all set screws/belts and they are tight. All other bearings have no perceivable play and are totally quiet.
Are you sure that no grub screws are loose there or no any way to fix this issue ? It looks more as something is not tightened or not fully assembled. This bearings are for industrial load and is hard to damage it, maybe just bearing housing is loosen ? We will shipping to you new bearing but replacement procedure of it is a little complicated and this bearings was chosen with keeping on mind that it should never fail.
Yes, I’m sure. The grub screws are tight and also the mounting screws (on all bearings, pulleys, rod holders, everywhere). I even loosened the grub screws and retightened them again. I really checked everything. You can create the same noise by directly grabbing the protruding part of the bearing (the flange with the grub screws in it)… There is no play of the shaft relative to the bearing. The bearing in itself has this extreme play. All the other bearings have zero play compared to that one.
Following my previous post just write e-mail there, we cannot keep a track only by requests done on the forum and forum do not contain field as - full name and shipping address.
