<p>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.</p>
<p>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.</p>
<p>What would make this happen? I could understand if it always printed like this, but it is <em>completely random</em>. 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.</p>
<p>I use Cura for slicing.</p>
<p>The following pictures are of the same print on the same printer using the same filament from the same file.</p>
