Print failure after one hour on UMS3


Recommended Posts

Posted · Print failure after one hour on UMS3

Hi there,

 

I’m experiencing multiple failures on my UMS3 since a few weeks now; I think my nozzle is clogging and the boden tube is pulled out of the feeder everytime…

I’m using a AA0.4 core and UM Tough PLA, just with the recommended settings…

this also happens with UM PetG and a AA 0.4 nozzle, again with the standard Cura settings…

Please advise, and help…

    It can be a real "clog", but sometimes it can be the fan in front of the cores not working. Did you check that?

    Hi RudydG,

     

    thanks for answering, and I have checked the front fan; its working allwright…

    I’ve unclogged the nozzle for a few times (hot ánd cold pull), but that also seems to have no impact.

    just now I noticed that the tube is being pushed out of the feeder in the first layer🥴, with just the front fan working; maybe that’s the problem?

    is the front fan cooling the filament down too much?

    I’ve reduced the flow down to 97%, and even that is not working all the times; after a few minutes the tube is pushed out again…

     

    printing with PetG, standard settings (fast) and the flow adjusted to 97%, there is no saying when it is going to stop again…
