Support is saying both motors are faulty. I don’t think so because, I can hear the 2 left idlers on the x axis making the noise and not the motors - but they are the experts, they know better. Anyway, they (Bambu Lab Support) want me to replace the motors on a brand new machine while risking to damage other components (acc to their WIKI big red paragraph )…well… I don’t think so. I’m trying to get a replacement because I found other quality issues with this unit (belt dust around idlers in the back, metal parts that were painted probably with an edding marker which, I could wipe off with alcohol -
see picture). Let’s see how this goes.
Beeing my first Bambu Lab printer, I am wondering how can they deliver something like this to their customers??!!?? 
I come from automotive industry where something like this is a big fat NO GO! Maybe I am just used to good quality parts, however their products are not cheap either…
