Extruder Clogging

Bambu Lab X Series Troubleshooting
1

Hello all, I have an issue with my extruder clogging every print.
Recently I printed about 4 spools of PLA-CF Filament (Maybe thats what damaged my Extruder)

For the last couple days I tried to print a part in PETG with PLA support.
The PETG works fine but everytime the AMS switches the filament to PLA the extruder clogs and I have to open and clean it.

I´ve tried 2 different spools of PLA because I thought the first PLA I used is old or kinda damaged.
But with a brand new spool there is no difference.

Is my extruder broken and do I have to replace it or is there any other chance of fixing this issue?
I´ve already installed a brand new hotend.

Thanks*

This thread seems to indicate that you’re not alone with this issue, and it’s to do with material compatibility more than the printer. Have a read, it may have a solution that works for you.
