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).

Hello,

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.

Hello,

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.

Has anyone found an actual, permanent solution to this? Changing these covers "fixed" my problem for a month or so, but they are back with a vengeance.

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.

agreed. Issue still exists... Covers changed, cables changed, every firmware since they turned on this feature. The ONLY solution I have to is clean the connectors with 99.9 ISO Alcohol before every long print. The "FEATURE" in the firmware is junk and WAY TO SENSITIVE. No reason to have it that I can see. The issue has ruined SO many prints. There is NO REASON for it to be a red-screen crash error and loose the entire print. How about a simple "Try again" prompt?

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"

Thank you for the observation. I have also noticed the flicker on the more problematic toolhead but have not gotten anywhere with support on it. Today I was about to start a print and it was flickering badly so I loosened the strain relief and tightened it back down which made the flickering go away. It's now 30 minutes into a print. I will keep an eye on this moving forward.

Any update on how the print went?

Same! Changed the covers and one of my dawrf boards and am still having this issue. I am extremely disappointed in this (and other) issues that greatly reduce our printers reliability. As a small business, we spent the money on this printer so that we could focus our time on more important things, yet I spend more time messing with my XL than my $120 Anycubic mono. I am beginning to doubt that the issue is the connector relationship to the print head and starting to suspect this is a hardware/software issue. I'm toying with the idea of ridding our shop of the XL all together and switching to a more reliable machine. Can you at least update here in the comments and tell your customers what you are doing to fix these kinds of issues? I want so badly to love Prusa but this makes it almost impossible. Please figure this out!!

El problema no se soluciona, ya reemplazar la nueva carcasa y nada. No hay solución

Still experiencing the issue on every alpha/beta/RC firmware all the way to today’s 6.2.6 RC. I’m using the new dwarf connector and it’s still an issue. I wish I could return this printer at this point.
