PetG trouble

Used an Rankforce PetG recently and it worked fine 

Last night a started a new print the Opentron Compatible 3x8 Tube holder from printables. 

Printed ist ständig with .2mm hf-nozzle 15% infill no supports

Quite frustrating waking up and seeing this ugly lines an top of every whole

RE: PetG trouble

Hi,

make sure the filament is dry. Otherwise it's futile. 

Then, check the "speed" view in Prusa slicer. The printer is coming from a slow section, then speeds up and something happens. The question is, why.

Check the filament path whether it moves freely or gets stuck in the PTFE tubes, then snaps loose.

You may be able to fix the symptoms by generally reducing print speed but of course that's just a hack not a solution.

I'd also do a cold pull, check the outside of the nozzle and the extruders (open idler, is there debris inside, is the wheel clean?)
