 Brand new to 3d printing. Got the P1S with AMS2 Pro. Buffer installed in back of P1S. I load the green sample filament and it's suppose to auto feed, which seems like it does, but it will go a couple inches past the buffer then retract fully and I get the error that there is no filament. Again new to all this, youtube is not showing anything helpful as all I keep finding are original ones or ones that are stuck. Is there a setting somewhere I need to establish to keep it pushing until it reaches the sensor/extruder? Kids are buggin me if it's working yet -_-. thank you.
