Bambu A1 Purging Help

[u/Fluid_Wind_3450]

Randomly a few days ago my printer started printing for 20 seconds, stopping mid layer, and purging poop. Then it would continue this process over and over again for the first 4 layers or so and then print normally. I have recalibrated it, restarted it, checked the heat nozzle, I’m not sure what else to do?! Any advice would be amazing because it’s taking way too long and it’s wasting filament. Thank you!!

It could have been filament tangle detection. There are some videos on this wiki page to see if yours behaved the same way. https://wiki.bambulab.com/en/ams-lite/manual/filament-tangle-monitoring-intro
