  1. Hey Guys,

    I really need your help. I just upgraded my printer with the Ultimaker Extrusion Upgrade Kit and since then the layers where I got 100% infill look really weird. Do some of you may know, what is causing this?

     

    Edit:

     

    I've tried lowering the speed, which didn't work.

  2. I would say that you have too many / too big retractions pulling heat in peak and Bowden ....

    (And maybe combined with printing a little hot or at a flow the hot end can't sustain)

    I did several testings yesterday and today and after them I can't imagine that there is something wrong with the retractions. (I heated the Extruder up to 200° Celsius and extruded 10CM with the UltiController and the same happened again, so I dont think it has something to do with retractions and too much Filament coming through) I also tested my Teflon coupler and it don't seems to be damaged at all. Any other suggestions?

  3. Hello,

    I have something weird going on with my hotend. I tried printing a part yesterday and noticed, that the filament stopped extruding. I thought that there was a problem with the extruder but when as I took the Bowden Tube out of the hotend I saw a big chunk of PLA at the end of the tube that there was no possibility for it to go into the Teflon coupler (Filament softened in upper head) . As I took the whole hotend apart to clean it I saw the PLA stuck in the peek insulator.

    I cleaned it and put it back together and the print worked for 10 minutes and then the whole problem appeared again...

    Any suggestions?

    With best regards,

    Julian
