Bambu!!! When will the k-factor finally be added as a separate line in the filament editing window, and not the disgrace it is now? This is not quantum mechanics, how long will we have to wait for such an elementary thing?
Answer: Till hell freezes over. 
Not to make light of your situation, but if you think Bambu reads these forums—much less responds—think again. When making demands of a vendor, you have to consider the same thing they are: how will it sell more filament or printers? In the case of the K Factor, which is clearly off, did it stop you from buying their filament or printer? Until it impacts their bottom line, venting here will find plenty of sympathetic listeners who are just as frustrated with Bambu Lab. Beyond that, it’s just us 3D printing enthusiasts providing the technical support that Bambu won’t.
