My first and only other Bambu printer is the A1 Mini w/ AMS Lite. I recently purchased the P1S with AMS 2 Pro and I was severly disappointed. The AMS 2 Pro was problematic from the very start. It would try to load filament super fast and then retract it superfast and I’d get errors when trying to print from it. The AMS Lite worked almost perfectly from the beginning and I can’t believe this AMS 2 Pro was so poorly programed or designed compared to the AMS Lite.
