I accidentally dried a spool of PETG in my Sunlu S2 at the TPU setting (56C). The PETG settings is 51C. I only printed one small sample swatch before drying it so I don’t really have something to compare to before/after drying. Everything I’ve printed after drying has a matte look. I know PETG can do that if you are printing too fast or too cool and my settings are fine (just trust me).

Could such a minor temp increase during drying cause the next 175g to all be matte? The spool is very nicely wound, I would have assumed that after a couple layers of turns things would revert to normal.
