Starting from firmware versions 01.08.03.00beta/01.08.05.00, the X1 series printers have introduced an authorization and authentication protection mechanism, aiming to comprehensively enhance the security of Bambu products. To ensure compatibility between the printer firmware and Bambu Studio/Bambu Handy, it is necessary to upgrade Studio and Handy to the specified versions.
