Hi again,
In my first reply, I thought you were talking about PETG instead of PET. I just printed with Siraya’s PET-CF, an absolutely outstanding material, using the default Bambu Lab PET-CF profile (only increasing the nozzle temperature to 290°C), on a Panda Build Plate CryoGrip Pro Glacier with a bit of glue stick. Perfect result and it detached without any issues.
