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).

I’m having the same issue. I’ve already replaced all the relevant parts, but the problem still persists. I keep losing long prints, wasting a lot of filament and time, and haven’t found a reliable solution yet.
Honestly, I’m starting to regret buying this machine. It’s been really disappointing not being able to complete long prints despite all the troubleshooting efforts.
I had already replaced the parts as instructed, but the same problem has returned after just three weeks. This is extremely frustrating — I bought this machine expecting reliability, but I keep facing the same issues repeatedly.
It’s really disappointing; I can’t even sell the printer in this condition. Please advise on a permanent solution.
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.
Someone noted on a forum somewhere and I can confirm. As the toolhead LED starts to flicker more and more, you know this error is coming soon. By cleaning the connectors with ISO alcohol the flicker goes back to extremely minor to no flicker. but as it gets heavier and more pronounced, this extruder error is coming soon.
PLEASE make this error NON-FATAL or give us the option to DISABLE this "feature"
