I was feeding Raspbery via jumper cables via the BTT motherboard. I was getting a voltage drop error on Raspbery from the beginning, but I didn't take it into consideration because it didn't cause any problems at first. Now when I had a problem, when I fed Raspbery with its original adapter, my problems were solved. I also had a filament jamming problem and it was solved when I lowered the retraction setting from 5mm to 1mm.
