Filament choices

this might be the wrong forum for this question, but here goes… i have the ender3 v2, im having awesome prints using carbon fiber PLA, buuut… not so good prints with standard PLA, any hints, tips?

I have the same issue with my Flashforge 3d printer. I tried to use PLA filament and it just stuck, and with ABS filament it is working completely well. I still didn’t find the solution.
