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).

You know I just purchased this. 5 head printer and you know I didn't buy this so I would have to fix a known problem that Prusa has known about for a very long time now. If I wanted to constantly have failed prints and constantly fix it myself I could have built it myself for much cheaper. I have had more failed prints from this super expensive printer than I have had successful ones.

Why is this still an issue? Can't you as the sole software designers of this stop it from crashing and allow it to restart the print instead?

Getting closer to wanting my money back.

I have for now placed the new casing a bit higher, +/- 3mm, so when you screw it down to the extruder it gives a bit more force on the cable and hopefully on the connector. Never had the old casing so dont know what can be done with those.
Fingerscrossed that this helps.

Has anyone else found a solution to this? I have wasted days and rolls of filament due to this error. I have never had this error until 6.2.2 with over a 1500 hours of printing before this issue. I can’t afford a 16 hour print always stopping at the 12th hour anymore. Might be time to find another printer for a daily driver.

did you contact support? you have to replace all the plastic cable covers with new versions that they send you. If you have removed the covers and the errors are still happening with individual tool motors, then they will have to send you new cable bundles, since those are permanently damaged.

As stated below, the new covers gave me the same error. My XL came with them already pre installed, still tons of prints stopping with this error. So dont think it's the only Solution, unfortunately.

No, but I already printed the covers on my own but still have the issue.

I too have been fighting this issue and have lost a lot of filament trying to troubleshoot the issue. I came to the conclusion that the stepper motor was stopping at exactly the same height every time. I installed the latest firmware yesterday and was delighted that the system was now able to detect exactly what I believed was happening. It is very strange though that it was happening at exactly the same height over and over again with different files. I had even reverted back to the older slicer version which made no difference. I think there is more going on than just the cover. I have removed the dwarf cover, unplugged and reinstalled the cable and now I have a successful print! This is still very frustrating though as this was a factory assembled machine and a lot of time and material has been wasted. I had similar poor experience with the factory assembled MK4. I am normally a Prusa advocate but very frustrated lately.

I wonder if the cable is barely wiggling lose, even temporarily which causes the print to halt?

It would be cool to have the print pause instead of abort when this error is received. That would allow some jiggling, wiggling, cleaning of any problems and the resumption of a print without the filament and time waste.

Exactly, now it just fully reboot and you can throw away everything. Of 10 prints 8 failures 4 at like 90%.

I Started to get this error on the current print on tool 2, upgraded to the latest firmware and still the same, I am now on my 3rd attempt at printing this project which is 2 colour 4hr print.

I have removed the cover as stated above.

Can not say I am super impressed as its 2 weeks old and cost 4k + and assembly was paid for in which I would expect an issue like this to be fixed already.

It is a work machine, so I really need it to be reliable.
