A1 with hardened steel nozzle PETG-CF able?

Yes PLA/PETG–CF works great. You will get a warning in Bambu Studio - hit confirm and print… I did set the bed temp to 65 for PLA-CF and 80 for PETG-CF. Make sure you are using Used 0.4mm Hardened Steel nozzle. Though the bed temp can go up to 100 C, I havent tried PA or PA-CF yet. Its hard enough on the X1C, why bother with the mini.
