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 guess they still had a bunch of these connectors and so it is the cheap solution.
I do not get why they did not put the screws at the same distance as the sub-d 9 ones because the the industry caps would have fitted.
What happens now is you fix the cable in the clamp an the wires have some flex between the connector and the backside of the connector. Over time this flex gets tension on it and the connector starts to strain and you get movement noise on the cable. The light starts to flicker. If the noise gets too big you get the motor error and the print fails.
The best solution would be a different connector, but that is a lot of work. Then a sub-d connector at the end of the cable and a sub-d with a short flexible cable to the print connector with a very stiff mechanical connection between sub-d and print head. The force and movement now all ends up at the sub-d connector. But this is a lot of work too.
The cheap solution may be to put a ferrite core around the cable and to remove the tension on the connector every month.
I ordered 5 snap-on ferrite cores. And if I really get angry I will make the sub-d solution.
I’m having the same issue. I have already replaced all the relevant parts, and it worked for about one week before the same error appeared again. I keep losing long prints, wasting a lot of filament and time, and haven’t found a reliable solution yet.
Today, the second extruder developed the same problem, which makes the situation even more frustrating.
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.
Now its possible between the 2 sides of the connector, or from the connector to the Board = bad soldering. Because i dont beleave that the cable is broken. (but will check this too)
Its not a firmware problem, its a electrical connection problem !

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.
