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 had the same problem for a few weeks now and always used the other working 4 printheads. I already replaced the cable- and dwarf covers but had no luck and actually don't wanted to invest more money for new cables at the time, so i googled a bit.
What fixed the error for me was fairly simple and i found it on the YT channel "Ro3Deee". He shut down the printer, disconnected the cable from the printhead, sprayed some pure alcohol or isoprop in the connector, cleaned the contact pins with a little brush and let it all dry. After reconnecting the printhead and retrying everything works fine and it also did for me.
My printhead always jammed after 2 to 5 minutes of printing with the error and now he's able to print nonstop hours again.
Hope that helps someone out there, before investing in replacement parts :)

I got a response from tech support mentioning that it has something to do with an old dwarf board connector. I have (4) Prusa XL's ([2] 2T's and [2] 5T's) and have been doing some testing because three of my four printers are throwing this error consistently. interestingly enough all four printers have the same dwarf board connector but only three of the four printers are running firmware 6.4.0 (the other one is running 6.2.5+8912) The one running the older firmware not only is not giving me the "motor not spinning error" but it is also the only one not giving me a "G-Code is not fully compatible" warning either. I am re-flashing another printer back to the 6.2.4+8909 firmware and going to see how it responds.

Did it work better? We have the same issue on one of the printers. It's the only 2T (the other ones are single-heads), but it's also the only one on 6.4

Does the same moter not spinning during a aliment set up an test for head one now! Must do a moter of extruder check during a aliment of pins an head then or something maybe? Thinking maybe its in the docking station portions of the printer then if it trips the error during a nonprint move as its not even nor should be a in print mode only an aliment of the pins ect for said dock you are calibrateing!
