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.

It's funny how I only get this problem since firmware version 6.2.4, which according to the release notes was supposed to fix this exact issue...

Me neither, over 6k hours and never had this issue. Get the error almost every other print now. Something has definitely been broken in the firmware.

I'm going to revert to 6.2.3 or earlier.

Hay guys and girls. I have a super simple fix for this. I got the idea from my old cr10 creality machines. they always used to put a dollop of hot glue on their connectors to hold them in place. Its a bit rubbish. but it worked and the glue was always super easy to peel off.

Anyway, remove the screw, make sure the cable and its sleeve is in the correct place in the plastic housing. Press the printed part (with the screw hole) in place. Put some downward pressure on the top of the printed part so it presses against the plug and holds the female and male together firmly put the screw back in with pressure still applied and then add the hot glue around the two printed parts to hold it firmly in place so that the downward pressure is not released. Only a little pressure is required to ensure the male and female plugs are secure and no wobble can be achieved. 3 little dollops on hot glu is all you need around the two printed parts. This can easily be moved later - it just peels off. Simple and solved in the most easy quick way.

It happens to me every 2 or 3 prints, for no reason. Step described above doesn't help, sadly.

I keep having this issue since i updated firmware as well. I completely disassambled the connection from main board to dwarf based on assamble kit and yet keeps happening.

I was soo excited to place my order for XL last year but with all the recent problems keep happening i might be regreting my decision now.

I'm still priting without any problem with my MK4 only the XL keeps having trouble.
