  1. Hi Sander,

    I really appreciate your help!

    Alright, I cleaned the nozzle, the first run did remove some dirt apparently, the second was clean, no more residue on the filament piece. Then I printed one more calibration cube (guess what, I have about 20 of them sitting here on my desk) - no change, there's still a gap in the very same place.

    I tried something: I ran Pronterface (the version included with Cura 15), moved the platform way up and then ran sequences of G01 Z30 and G01 Z-30 commands to slowly move it up and down, up and down. I've made a video where you can hear that there's something non-linear in the movement:

     

    Maybe this helps find the reasons behind the problem?

    Regards, Phil

  2. Hi -

    thanks for the warm welcome.

    The first skip occurs at 10mm in most prints (there were two out of 10 prints that didn't have this one), the second at 13mm height (in all prints I made in the last few days). From there on upwards I've also had the impression of constant underextrusion, but this might be due to my tuning efforts.

    I've used the following filaments (all PLA @2.85mm): Ultimaker's own (silver), Prima Value (black), Das Filament (pink), eSun (brown). Currently I'm printing the same test cube from the SD card using the brown filament from eSun.

    Could "simple" underextrusion occur at the same height every time?

    Thanks for your time and efforts!

    Phil

  3. Hi folks,

    I had hoped my first message would not be one about a malfunction of my cute new UM2GO, but sadly, I'm experiencing problems. My prints show a gap at certain (constant) heights:

    I've already cleaned and greased the Z axis trapezoid screws. Manually moving the print bed up and down, I can't feel extraordinary resistance at a certain point. I've also set all currents to 1200 mA, as advised by Ultimaker's German support rep, to no avail. I tried like five different filaments, different temperatures etc...

    I'd be happy if anyone had a suggestion - I'd love to be able to print anything higher than 12mm.

    Thanks, Phil
