Bambulab responded to my support ticket last night after 29 days of total silence and 10 attempts by me to get them to escalate the matter. 11 or 12 attempts if you count the second ticket I felt forced to open - which may have done the trick since they did respond to that one after only 2-3 days, lol.
Unfortunately they’ve failed to say anything useful, have gone off in a totally different direction, and ignored their earlier promise of a refund on this printer.
They are clearly completely incompetent and it would be laughable if I wasn’t out over $650.00 and owned a printer for a week that I haven’t touched in four months.
