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.

You were right! All clogged up.

Replaced the nozzle, heat block (heating element, sensor, PTFE) and fan duct. Wasn’t able to unscrew the nozzle (got stuck 80% out) so I replaced the whole thing.

Did two new temp towers:

Left tower is 235 (top) to 260 (layers labeled 280-260 are all 260). Right is 220-240.

I definitely feel like 220 is the right temp for this.

Make sure you calibrate your e-steps after swapping hotends. I did the same thing on my ender 3 putting on a volcano hotend, and started getting overextrusion. After adjusting the e-steps it was back to normal.
