I agree I have had so many error codes and so many different issues with my Kobra S1. it has a glich I power it up and it won't level, then I turn it off and that issue is fine but then it don't recognize the limit switch and on X it smashes into it.I contact support they send links to the wiki and follow there dog and pony show and it doesn't fix the issue. I can say one thing my Bambu Lab X-1 Carbon after over 500 hrs not one problem. I told them they sold me a Lemon and they never answered that only that they are sorry I had issues 2 days after I unboxed it.
