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.

I got this error because the "dwarf-cover-connector" was too loose - not too firm. The following steps resolved the issue (printer switched off):

1. Disconnect the toolhead cable.
2. Open the dwarf-cover-connector by releasing the bolt (as explained in this article).
3. Reposition the white connector in the dwarf-cover-connector housing.
4. Fasten the bolt.
5. Connect the cable to the toolhead.

I had exactly the same problem, even on 6.20 and greater firmware. Happened most frequently on Tool 1 (even if I swapped in from a different Tool) and once on Tool 5 on the 4th day of a 5 day print. I found that you couldn't resume the print after this failure to be quite infuriating.

FWIW, I think applying firmware to fix this problem is a bit of a stretch despite the stated "tolerances" justification.

In my case, installing these fixed it: https://www.printables.com/model/1124941-secure-xl-nextruder-cable-connector-solution

Just updated to 6.2.4. On extruder 1 the print fails at exactly the same place (end of first layer) a on 3 different attempts. I re sliced the file between attempt 2 and 3. The first 2 attempts had 3 objects. The 3rd attempt had only 2 objects. They all failed exactly at the end of the first layer. I find it hard to believe that this is a cable issue.

Same file works fine on extruder 2.

It says "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."

This is the most idotic thing I have ever heard. Your telling me because the connector is held in place to good making to good of connection is causing the extruder not to turn? And by simply removing the cover fixes it. I call BS. Come on Prusa, I'm running FW 6.1.3 and extruder 1 fail every single time.. on had printer a few months... come on PRUSA.. do better!!!!!

Where are you seeing fw 6.2.4 for the XL? I am only seeing 6.2.2 and would love if new updates would fix these problems.

Ah wonderful, thank you! Hopefully this version fixes these issues.

Update: after my 3 hour 5 color PLA print with the new firmware update, this error has not reappeared. Good news
