Hi,
I’m printing with Elegoo Rapid PETG on a X1C with Bambu PETG HF settings.
The print is approx 240x240x15mm, 75 layers with gyroid 15% infill, 0,4mm nozzle, ironing is OFF.
The print goes very well for the first 74 layers. At the top layer, it seems that the filament doesn’t stick well to the underlying layer.
Between these areas, the print quality seems to be very good.
These visible ‘waves’ seem to be areas where filament doesn’t stick at all to the bottom.
How can i avoid this phenomena?
Any comment and help is highly appreciated.
