Hi hope you can help.

I have a FF Creator X , i used mostly the right nozzle with no issue, lately when i used the left nozzle is very common the filament is not feeded or get caugth on the bearings and some times clogging, I though it was the pulley (worn) I change it but no luck.

I use the same temp and speed for the right nozzle and try change them for the left but no luck

any advice? thanks.
