So I had today some really great big prints with PETG-CF and wondered what changed. Nozzle collected not very much filament and the overall print looks super clean. I then realized the following changes in my printer setup, as I didn’t print for a while with PETG-CF and was annoyed to search for good settings, I completely forgot about the problem with PETG-CF.
So these are the changes since I opened the thread:
- Set the print temp to 260 °C
- Infill Gyroid 15-20%
- Auxilliary fan to 20%
- Chamber fan about 60-70%
- 0.6mm nozzle instead of 0.4mm ( I just used the 0.6mm because my 0.4 got damaged, so this was just a lucky shot)
- and the most important setting I think I changed was the seam position which was always “Lined up” or “backside” and I changed it for TPU to “next” and never changed it back so also pure luck.
The rest is standard settings from the Bambu PETG_CF profile
Maybe somebody else can verify if he gets better results with these settings too.
