A while ago I had an Ender 3 Pro which I upgraded with a BL-Touch and self-printed parts. It worked great and was reliable but not something I would call plug and play.
Is there a clone that's relatively plug and play? I don't mind assembling but don't want constant readjustments.
Prusa is more expensive and better mostly because its built better, not because of software. Any open source (marlin) board can be updated by user and its also easy to flash klipper for example.
Constant readjustments are due to bad design and no QC. If you want more reliable printer dont look for knockoffs. My first printer was prusa knockoff, it looks better than prusa, steel frame with no printed parts, but its not even close. Its collecting dust now
