I bought an Ender 3 v2 in January 2021 for my second printer. I have had an Ender 3 for two years and love the quality it prints. This new printer has been plagued with issues since day one. Creality sent me a new mainboard and fan due to issues. Even since then my printer will still not print consistently. I checked all my belts and made sure the bed is leveled.

I print a test cube and it looks perfect. Then I will print a bigger longer print and sometimes it looks 100 % perfect with smooth layers and then I will print the exact same print from the same memory card and there will be ridges every couple of layers and the print turns out very rough.

What would make this happen? I could understand if it always printed like this, but it is completely random. This is all from the same filament spool and I only use Hatchbox. My Ender 3 hasn't had a single problem in the two years I have owned it besides changing out the Bowden tube twice.

The following pictures are of the same print on the same printer using the same filament from the same file.
