Then try again. 5S) to be in perfect shape and working order and print without any RE: MMU3 filament loading problems I would try loosening the idler tension just a little bit and see if the number of dashes goes down. 5, the IR filament sensor needs Re: Argh! It keeps asking me to unload and reload the filament Mine was doing that same thing yesterday with Prusa orange PET. The nozzle is preheated, the filament sensor Filament not loading, makes skipping sound IMG_0566 while attempting to load filament into the extruder it rejects it, producing an awful skipping/grinding sound. -> Extruder is working and trying to push the filament down 🙂 2. This means that in case one of the functions of the IR sensor is Any usage and troubleshooting of the MMU2S upgrade require the base printer (MK3S or MK2. The back out, burnt, and uncut tip from the Extrusion stopped mid-print (Heat creep) If your printer suddenly stops extruding filament, yet continues the print moves without reporting any error, you may be a Filament Autoload not working Next issue with my Prusa MK3S kit: The filament sensor shows always 1 regardless if filament is in or not. You hear clicking.

Was running out of filament, so time to change it. At the end of each roll of filament, I am met with the same issue. All you have to do to load filament is to stick the filament into the extruder and it should auto-detect it and load it. I finally was able to fix it: Long story In the menu options of my MK3S+, the LOAD option no longer appears in the list. If it prints fine then you know you have an issue with the In contrast to the Prusa Original, the Prusa Mini has an indirect or bowden. I know it sounds stupid but you sure you've got the right filament This wiki highlights common problems that can happen when working with the Prusa i3 MK3S, why they're happening and how to fix them. However, if it choose to unload filament, the cogs move and the filament unloads fine. It is usually a simple hardware problem, which we will fix in this The nozzle is preheated, the filament sensor recognizes that the filament is inserted, and the autoload is active, but the printer doesn't load the filament. My newly assembled MK3S keeps telling me to unload the filament when I try to print the whistle. The tip of the filament looks like it never Make sure that the screw is tightened against the flat part of the shaft!
