Grinding at end of print?
My MK3S+ has been printing fine for two years, and still does, but lately at the end of some prints, when the extruder lifts and goes to X=0, there's a terrible grinding noise for a few seconds. As far as I can tell, it's the left Z axis threaded rod/motor trying to do something. The two Z rods/motors appear to be in sync - i.e., the X axis is level, and nothing is in the way of the extruder getting to X=0. Any thoughts? The only thing unique here is a Revo hot end; all software (PrusaSlicer, firmware, etc.) is at the latest versions (Revo version off Github).
RE: Grinding at end of print?
i've been having a similar issue. before doing a color change, there was the grinding noise. immediately after loading the filament and continuing to print, the nozzle dive-bombed into the bed. i immediately stopped the print. now i have a large gash in my steel bed and i'm having all sorts of trouble with the extruder not having consistency with the volume of filament being extruded.
