Do a temp tower. Find one hottest to coolest (260 to 220) and see where the sweet spot is. Going coolest to hottest could cause clogging.

And when in doubt make sure you PETG is dry. Likes to pull in the moisture. Tell-a-tale is popping and hissing.

Others: correct if I’m wrong but black PETG tends to be on the warmer side then other colours?

In my experience, moisture will cause excessive stringing in PETG long before it is saturated enough for popping/hissing.

I did two temp towers: 260-225 Image

And

280-235 Image Although my printer didn’t want to go above 260, so the first layers are all 260.

  Yikes! Are you sure you sliced the temp tower for PETG profile? (as others have inquired)
