Printing problem on Ender 3 after change to 4.2.7 mainboard

[ShizzyFox]

Hello everyone. I am somewhat new to 3d printing. I tuned in the printer when i had the 4.2.2 mainboard and it didn't have any of these issues that are showing up now ( see pictures). Then i changed mainboard to the silent 4.2.7, and all of these z banding started to show up and these tiny holes that always show up on the right outside side of the printer and the left inside of the printer. when in spiral mode non of these problems show up.I have looked at many videos on z banding and so on, and i have calibrated the axis and looked at their movements and i don't see any issues with does. what could this problem be and how can i solve it?Thanks in advance
