Bambu’s PETG-CF is amazing filament if you ask me. It looks great, it is good for functional parts and with a bit of changes, it also prints very nice.
Try following:
- Use OrcaSlicer so you can set pressure advance
- Filament settings change following: temp to 265 (except first layer 255 to reduce oozing during first layer print), bed temp 80 (use textured plate or high temp plate) and pressure advance 0.032
- Reduce print speeds a bit - check pic, these speeds I use
Print with closed door and lid. Your chamber temp should be between 40-45 for ideal results. Before print, uncheck “Flow calibration” - it is not needed.
Regarding overhangs - there is a bug in OrcaSlicer in current version, so slow downs for overhangs doesn’t work. If you have a model with many overhangs, consider reducing outer wall print speed.
If you do it like I suggested, then you will get results like this:
