So I was putting my printer back together today and after I mounted the extruder head back in the gantry, I realized one of the bushing covers/sleeves was bulging out and the reason was because it broke . I have replacement covers and as a matter of fact, I have some graphite plugged bushings that I never installed. My question is two-fold. First, is it worth the effort to replace the bronze bushings entirely, since I already have the printer apart? Second, I don't want to misalign this broken one, so is there a good way of taking out that belt without "losing my spot", so to speak? I'm worried that taking apart those gantry rods to replace the bushings is going to be a lot of effort because I will have to realign everything, but I've never done it so............................? The printer is completely apart because I found a curious problem on the lead screw that could quite possibly have been my problem all along with homing, UBL, everything. The lead screw can actually jump up and down when the motor is mounted and I have seen it do so. So I'm replacing it completely. EDIT: The only caveat is the graphite plugged bushings I have are 6mm shorter than the original bushings. However, I don't think that would be an issue.
