Another PETG Stringing Problem (Core One +)
I'm attempting to print a part with Overture PETG (Project file attached). The first one printed perfectly without stringing. The next day I printed a second one and it had lots of stringing. The relative humidity in the room was at 50%. Assuming that the filament had absorbed moisture I ran it through a drying cycle and printed another today. It is just as bad.
After the first print, which was successful, I tried to nip off a string hanging from the nozzle with a flush trim cutter. I got a little higher than I intended and as I squeezed the cutter I felt it slide off the nozzle. It's possible that the cutter damaged the nozzle tip.
Is it plausible that I may have damaged the tip and it is responsible for the stringing?

It's possible but doesn't seem super likely. Can you get a bright light and a mirror under there to examine it? Maybe a magnifier too.

If the nozzle is brass then yes, it's possible to nick it with steel cutters.
As for stringing best advice would be to print a temperature tower and try to dial in the optimal temperature that reduces stringing. Or (my mantra) switch to PCTG.
