Material Station aborts feeding TPU on Extruder 2 - Ultimaker S5


Recommended Posts

Posted (edited) · Material Station aborts feeding TPU on Extruder 2 - Ultimaker S5

Hi, i use first generation of S5/Material-Station combo. Not sure how much Material station has been improved meanwhile.

 

I am printing a combo of ASA + TPU, and therefore loaded AA4 nozzle into Extruder 1 and 2.

 

I have the odd situation that TPU is loading and printing correctly through Material Station on Extruder 1.

But it does not work on Extruder 2 with TPU in Material Station setup for Extruder 2.

 

When trying to print exactly same TPU, with same profile (also tried generic UM TPU profile) loaded into Material Station 2 for Extruder 2, Ultimaker aborts  feeding material right when it is half way in the bowden tube between feeder and nozzle. It aborts with an error that "broken filament is stuck" what doesnt make any sense and asks to start the wizard. I tried also material bay B2 and E2, with no difference.

 

Any idea? Is the Material Station only able to deal with flexible materials in path of Extruder 1?

Thats my current workaround to print the main part on Extruder 2 and the flex parts on Extruder 1.

 

Thanks,

FG

 

p.s. Cura 5.2.1 and UMS5 7.1.3

    Hey @flyinggorilla,

     

    That's quite odd behavior and it doesn't sound familiar. 

    Flexible materials should be available in both extruders!
    I've heard some stories where the material bay had influence on the ease of loading materials. 
    Did you try changing the bay where the material is loaded? 
    Perhaps, if something is stuck in your bay you can follow these steps to clear the tubes out

    I'll ask around if there are other tips to help with troubleshooting 💪

    thanks, yes i did. no difference, exactly the same behavior. I had tried material bay B2 and E2, with no difference.

     

    Note that placing ASA filament instead of TPU (so pretending it was TPU) did feed correctly, so it must have to do with the flex of the filament relative to feeder progress detection sensor items or path differences it goes.

     

    thanks for checking on other tips.

    Hey @flyinggorilla,

     

    Some of the suggestions I've been getting are.

     

    1.  Make super sure that your filament is pointy before you load it in. Make sure you cut it off with the pliers before loading it. 
    2. You've probably done this already but you can check this support page with tips https://support.ultimaker.com/hc/en-us/articles/360016971619
    3. Clean the feeders and check the tension as instructed here: https://support.ultimaker.com/hc/en-us/articles/360011652139-Clean-the-S-line-feeders
