I recently purchased a spool of PETG to try working with it. I have managed to dial in most of the settings in Prusaslicer but one, in particular, is giving me a problem. As seen in the photo, the clip I printed has extra extrusion on the inside and outside. I have noticed that the nozzle will pause at the seam for about 5 secs before continuing. (The bottom is not Elephant's foot, I just didn't clean off all the brim)

I positioned the seam on the inside of the model. I know that the extra extrusion is caused by the seam but why would it also appear on the outside of the model?

I have printed the same clip in PLA without any printing errors. What setting within Prusaslicer needs to change so I can get rid of the extra plastic on the inside and outside of the print?

[I don't know what relevant print settings are needed to solve this problem, but will edit the question when I get some guidance.]

After checking several places online, I finally got an answer in a Discord chat.

The solution was to turn off the Power-loss recovery setting on the printer itself.

After that was done, the print came out beautifully.

Looks like Retract at layer change is causing this. Disable that and see. This will help you to improve the quality a lot.

It will be under retraction settings:
