I’m experiencing an issue with my infill—as shown in the images—and a band is forming along the bottom layers on the exterior. I’m using Atomic PETG PRO at 250°C, a bed temperature of 75°C, and a fan speed of 30%. The filament was dried before printing. It appears the nozzle might be contacting the material, causing the issue to worsen until I eventually cancel the print. Any suggestions would be greatly appreciated!
Maybe try a different infill that doesn’t cross itself, like gyroid.
