Step 2 Releasing the cable bundle. ⬢ Using an Allen key release the M3x40 screw and open the door. ⬢ Release two M3x10 screws and remove the extruder-cable-clip. On older printers cut the zip tie. ⬢ In case there are zip ties inside the Einsy-case, carefully remove them. ⬢ Remove the zip ties on the cable holder.
Extruder clicking during retraction
The retraction was in fact the filament slipping on the extruder gears. Best way to diagnose this problem: unload the filament and reload it. If the extruder clicks during loading and too little filament is exiting the nozzle it is a partial clog. Keep replacements nozzle on hand, they are not very expensive. Thanks for the help.
Extruder stepper motor goes CLUNK, CLUNK and skips – Prusa …
The extruder stepper motor sometimes makes a CLUNK sound and doesn't appear to extrude the right amount of filament. It seems like something inside the stepper motor is slipping. The problem is not with the extruder drive gear on the motor shaft. It is tight. The pinch wheel the on the opposite side of filament from the extruder drive gear is …
Extruder skipping steps – Assembly and first prints …
MK3S+ prints for approximately 1 hour then jams and stops . After about 45 minutes, I begin to hear intermittent extruder clicking noises. After the part stops , I shut down the machine and attempt to remove the filament. It becomes stuck in the PTFE tube and I can only remove it if I heat the nozzle to 270 and then pull it out.

Prusa i3 mk3 step skipping and layer shifting
3. After approx. a year of more or less problem-free (40 days print time) with Prusa i3 mk3 kit, we started to suffer the random layer shifting on Y axis. We inspected all the motor connectors are properly inserted in the mainboard and the wires are intact. We ensured all the pulleys' screws on the x/y motor shafts are very tight and ...

MK3 Extruder Skipping
6. Run the procedure described in STEP 1. You should be able to run the extruder with at least F450-F500 speeds. I was able to run with F800 with no clicking. 7. If confirmed that this is in fact the extruder motor replace it witw a new motor. Put the X-axis motor back in place and order a new extruder motor from Prusa shop.
extruder skipping – Hardware, firmware and software help
extruder skipping. I got a I3MK3S less than a year ago, printed only 3 spool of PLA and 1 spool of PET (all Prusament), I used only the default settings from prusaslicer (no mod of any settings) Everything worked fine until two weeks ago where no filament came out at all. I cleaned the nozzle (using the niddle shipped with the printer)

Clogged hotend (MK4) | Prusa Knowledge Base
Extruder clicking. The hotend or the nozzle is partially or fully clogged and the internal resistance against the flow of the filament is greater than what the gears are able to push. As a result, the gears are skipping leading to the "clicking" noise and in most scenarios also to the grinding of the filament. How to fix the clogged printer?
