I attempted to start a print and I am getting all 4 leds giving me a red double flash. I have turned the X1C on and off and unplugged the cable to the AMS with no improvements. The last print finished fine. Bambu studio cannot contact the AMS for a filament update. Other then starting to pull the unit apart I am unsure how to proceed.
There are typically reasons for issues with the AMS, as most are easy to solve. I assume the printer doesn’t detect the AMS. If so, follow the: AMS is not detected by the printer.
