Preface: I’m on my third cheap printer in the past ten years. I bought an Anycubic kobra neo a few years ago. I told myself I wouldn’t mess with doing anything to it, but I was running into issues because of low quality control. I put it away due to frustration for the past year and now needed to print something and just figuring out all the issues. Right now I’m looking into upgrading the part cooling fan as I cannot get rid of stringing even on low temps with PLA. I should just buy a good printer but I just don’t feel like I can justify it.
OP didn’t specifically say “only use the parts that came out of the box”. It’s still ambiguous. Are official mods, like PRUSA MMU modifying? How about after market parts?
Let me propose a modification tier list:
I’ve personally done all 5. I can’t imagine everyone has done all tiers of modifications.
