OP bought a used Ender 3 v2. OP had it working just fine, until it needed repair, and stopped doing the thing it’s designed to do - print. Then, OP bought a K1 because the Ender printed fine. It’s not a skill issue, champ, I’m doing just fine. I don’t think you actually read my posts at all. If you did, you having a reading comprehension issue.
When you use a good printer, it’s hard to look back at the older ones. They are, as you said, pretty dang jank.
