Hi there,
I just wanted to share my little experiment. Perhaps it will help you when using eSUN PETG +HS (high speed).
I used the default settings provided by eSUN considering the material properties and the slicing process. I did not dry the material, just used it “out of the box”. First of all I did a stringing test - result: zero stringing, so moisture didn’t seem to be a problem. Yet, I had massive problems with overhangs, so I printed an overhang test: Left Part
Then I searched the PETG issue on the bambu lab forum. There are a lot of recommendations like:
- not enough cooling
- too high printing speed (outer wall)
- deactivate “slow down for overhangs”
- dry your filament
Changed part cooling min from 10 → 40% and max from 40% → 90%
Massive improvement: Middle Part
Additionally I changed the printing speed. → deactivate “slow down for overhangs” and set outer wall speed to 60 mm/s
Almost no improvement: Right Part
In the end it just was the part cooling.
Probably you can even tweak it further, but so far I’m satisfied being able to print a 45° overhang.
