Hi Jeff，
Hope you are doing well.
The recommended dryer temperature for the PETG filament is between 60-70 ℃, and the drying time is 6-8 hours. We suggest that you set generic filament models on Bambu Studio,and first layer of the printing nozzle is 235℃, and other layers 230℃. The hotbed can be set to 85℃.
Have a nice day.
