I have had so much problems with eSun PETG for the specific products i'm printing. Zits, blobs, nozzle buildups, weak layer adhesion, etc.
Well this is a PERFECT profile for me now! The before and after results are crazy.
All you need to do here is a FLOW RATIO calibration and then just hit print!
This profile i'm sharing is for the SILVER PETG from Esun, and this particular color needs higher flow ratio than the other colors - like red, it's at 0.952, wile Silver is at 1.02.
