First time with PETG. Is this calibration, wetness or something else? (imgur.com)

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.

Update: replaced the nozzle, heat block (heating element, sensor, PTFE) and fan duct. 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.

I’ll try the bunny again, the model is designed for vase mode, so it should work!

You could also mess with your retraction settings to try and reduce stringing.

I had one weird roll of PETG that could only be printed at lower temperatures, so it's possible. Still looks like the filament is wet to me... I recommend picking up a Sunlu S1 Plus when it drops under $40, I like being able to both dry the spool and print straight from the dryer (only takes a couple hours to re-absorb moisture).

Dude! I just checked AliExpress for the Sunlu S1 Plus when I saw your message and was able to get one for $39 (shipped from Germany)! Thank you for that idea!

Make sure it's from one of Sunlu's official stores... aliexpressis pretty shady lol.
