Been using this printer for a couple of months now, and I still can’t perfectly tune the stringing settings for CR-PETG. This prints a stringing test at 240C, with 7mm of retraction at 100mm/s.
i had some PETG from Tecbear, in the end I had to adjust the flowrate down to 85% to get rid of stringing. I normally print Pinuotu PETG at 100% without stringing. I only changed brands because of a small budget benefit. I shall go back to Pinuotu brand.
