What is wrong with this unit, do I need to take it back?
I have tried everything I can think of! Reset to factory twice did all the proper maintenance lubing greasing etc etc.
I really doubt this very much! does Bambu Labs have a phone number you can call for help?
That is the problem with these products made in China!
Creality was the same way had to dump there butts returned both machines and got my money back!
