Weird effect while printing

  • Ok thanks to a moderator or admin here. I found out that my z motors was outer sinc. Bit after 2 test prints i am stuck. I dont now how to solve this. Can some one help me.

    Motor / Jerk settings.

    And here my printer with bountech ectruder. Love this extruder

    My guess is that those bumps are happening on layer changes. Getting rid of such artefacts completely is not easy, but selecting "External perimeters first" (or "outside-in") and enabling "Retract on layer change" in your slicer may both help.

  • If you are using Cura spiralize mode, ensure that retract on layer change is off! (the next release of Cura ignores that setting when spiralize is enabled).

  • Wow thanks guys i am testing some settings. But i must say great support from you guys. I love the duetWifi its nice and much nicer to change settings then Marling with the ramps board.

    Thanks for the help
