I keep experiencing issues with longer prints where the bearings are sliding out causing the print to fail because the extruder drops. Is there something that should hold them in place better or do they need to be oiled?
Oiled for sure. The bearings on the extruder can get a little loose from over tightening the extruder mount as well. It flexes the back piece open…tough problem to solve on my end,the alternative tends to pinch the bearings and ruins the rails.
