A1 printer

The printer was doing good from things downloaded from Makers World. Than in printing, about every 6 to 10 seconds the printer would stop. Than do a filament purge. Reboot the printer and redownload the file to it. Once it worked fine. Than at the start at every print job. It would start to do its normal purge. Than the head temp would drop to 150c. To the purge could not finish and the printer would think the filament was jammed.

Than I did a factory reset. Than the first problem came back! PLEASE, what is going on and what is the fix? Please, the printer is now a brick.

Oh, its been 2 days with no response from Bambu support.

Have you tried a different SD card? You will need to format it via the printer display. A failing card can exhibit symptoms like you are seeing.
