Been using prusaslicers default PLA profile with issues and this is my first roll of PETG, so I just selected the corresponding profile for that.

It seems so be super stringy whenever there’s movement and when printing the bunny (in vase mode) there’s lots of holes in the model.

I’m not sure if this is an issue with calibration (didn’t do anything when switching from PLA) or if the filament is wet.

    I’ve always understood petg to really like cooling but I print in an enclosure so YMMV, it’s absolutely awful for bridges without cooling. Another thing to check would be extrusion multiplier and retraction. I get nozzle buildup if it’s overextruding which leads to blobs and stringing, worth tuning that anyhow

      Been doing a couple of test prints with 30-80% variable fan speed and it’s actually pretty good looking with almost no stringing.

      I unfortunately don’t have an enclosure, else I would for sure try and higher fan speed. Ad a slight draft this morning and my calibration cube print popped off half way through.
