EXTRUDER ERROR #17536 (XL) | Prusa Knowledge Base

What happened?

The printer shows the message "Extruder motor is not spinning on tool #". In place of #, the number of the Dwarf board is shown.

This problem occurs due to increased resistance between the Dwarf and the cable connector, caused by the cable and connector being held too firmly in position.

Error name: Extruder error

Error code: #17536

How to fix it?

Update firmware

Make sure that you have firmware 6.2.0 or newer.

Remove the 'dwarf-cover-connector'

Remove the dwarf-cover connector, as it might hold the cable and connector too firmly. Fully loosen the bolt holding the part and remove the bolt. Repeat the print without the cover. If the issue is solved, replace the cover: How to replace the main cable connector cover (XL).

If the issue is not solved, contact our customer support.

Has anyone found an actual, permanent solution to this? Changing these covers "fixed" my problem for a month or so, but they are back with a vengeance.

I have been dealing with this on and off for months. I have had numerous conversations with support and all the "solutions" are temporary at best, as the issue persists. If there was even just a way to power cycle the printer and resume printing it would be an issue that I could live with, but this printer is so unreliable that I can never trust it to finish a print anymore. It has wasted so much filament and time.

El problema no se soluciona, ya reemplazar la nueva carcasa y nada. No hay solución

Still experiencing the issue on every alpha/beta/RC firmware all the way to today’s 6.2.6 RC. I’m using the new dwarf connector and it’s still an issue. I wish I could return this printer at this point.

Ha, same issue, always head one is complaining and the connector is seated properly, looks like when head is moving it looses connection and FW kicks in unable to continue in printing. Would be nice, in FW would provide a test which would revel that cable connection is cactus by moving the head around and testing the connection. In my opinion this connector on the head is not suitable for moving cable.

I struggle this this problem since months. I finally contacted the support and it turned out that Prusa also redesigned the darf-cover connector and some related parts. You can find it between the Nextruder files: "dwarf-cover-base.stl", "dwarf-cover-connector.stl" and between the Maintenance files: "dwarf-cover-connector jig.stl". Assembly guide is here: https://help.prusa3d.com/guide/how-to-replace-the-main-cable-connector-cover-xl_831370#831767
The issue came up because they implemented a feature with the new fw capable of detecting the issue... so it is a real issue it was just not detected earlier :D
I hope the new connector securement solves the problem.
