Problem printing with new roll of Bambu PETG Basic

Bambu Lab P1 Series
1

I am trying to print with a new roll of Bambu PETG basic. I initially had an issue with a dirty PEI plate. the first 3 layers went down perfectly. When it came to the infill, things went ugly. Its like the filament is not sticking. I tried the calibration and that did not seem to work. I am not sure what to adjust to get this printing well. The infill is 15% adaptive cubic.

This was a model that I found on the Maker World site (Meta Quest 3 privacy and controller stand remix Remixed by dabsi_ - MakerWorld).

That model profile is for PLA…
Did you change the filament to PETG in Bambu Studio…??

PETG temp is 255* for Bambu & 220* for PLA.

Yes, I did update it to Bambu PETG Basic before printing. I did see the temp go up to 255.

255C is still to low for PETG. I’ve run at least 1kg worth of Bambu PETG doing different tests. Found the best temperature is 262C. That is good for at least the 9 rolls I currently have. Another thing to look at is under Filament settings, the cooling TAB. Might need little more or less cooling to allow for the adhere of the plastic.
