I am printing a plate of various knitted animal models on my H2C in PLA Basic and PETG for support interface. 95%+ of the model is printed in the PLA Basic on the left nozzle and every layer of the model uses this filament.
During printing I noticed it is using PETG in the prime tower walls on certain layers. I am concerned this may cause structural problems with the prime tower as it grows higher. Is there a way to exclude PETG or other support materials from the prime tower walls?
Left Nozzle: PLA Basic
Right Nozzle: PLA Basic (x2), PETG
