I used to change filaments during print using "Change filament in the Bambu Studio. Since the last time I updated both Studio and my A1 firmware and now when try to do it, it doesn’t work anymore. I don’t have AMS lite, so I wanted to do it manually and it worked before. The printer itself, when it comes to this filament change, just stops printing, goes up a little bit and then again down, and continues printing as normal (the print is totally fine, just I can’t change filament). However, the option “Pause” works as expected, so I don’t know what causes the problem, for me it’s something wrong with Bambu Studio.
