Material in use (permanent) when not printing - Ultimaker S5 - FW: 8.2.0

Hi!

 

I have an issue with an Ultimaker S5: when i try to unload material it says "material in use" even though i am not printing. The indicator light is blue (see ).

The PLA seems damaged.

Inspecting the back of the printer i see material stuck in the bowden tube below the feeder.

 

I know how to open the feeder for cleaning, but i cant find any guide for unloading the material!

Is it a sensor issue or mechanical issue?

Please refer to relevant guides or videos if you have experienced similar issues.

 

Thanks!

Johannes

Is there a solution to this problem?

Which problem.  Is your PLA also damaged?  I don't have a MS but I've seen documents that explain how to take it apart and remove stuck filament.  Ultimaker has some great documents with pictures and detailed instructions.  If that won't help then I'd contact support.  Click the 9 dots icon in the upper right of this screen, choose support and then near the top of the screen choose "submit a request".

I have two S5 with the Material Station in use and can confirm that this problem can sometimes happen for multipe reasons, e.g.:

- Print aborted due to some error

- Material gets stuck during the initial loading process

- Switching to a new spool during print fails

- Power outage while material is loaded

 

The concequence is usually that the printer has to completely restart, after that the material is still recognized by the printer and the material station (blue light) but can't be unloaded. If this happens, there are two options:

 

1. Load another spool of material in one of the slots of the material station. Which slot and which material is irrelevant. Tell the printer that this material is of a different type than the one which is stuck. So for example if PLA is stuck, tell the printer that you just loaded ABS. After that, prepare any part in Cura with the material type you just loaded and start this print. This will usually force the printer to unload the stuck material. While the printer is unloading, manually remove the spool you just loaded by pushing the button on the material station. The printer will give an error because the material it needed for the print isn't there anymore. Restart the printer and your usually good to go. Works 90% of the time I would say.

 

2. If 1. doesn't work, the material has to be removed manually. It's basically the only other option, if you don't want to take the printer apart. Turn of the printer completely, pull the power plug on printer and material station and open the feeder if the material is stuck above it. Then very slowly pull the material back out from the material station. Be warned, you have to use a bit of force and it doesn't make the nicest sound while doing it, but its basically the only option. I guess I had to do that about 10 times in the last few years and both material stations still work absolutely fine.
