I have the same problem. My A1 is new and has not yet printed once. I go through all of the calibrations and select an item to print on the attached micro card and it goes through all the setup motions, but the last thing it does is go over to the cutter and cuts the filament then moves back over to the pooper and throws the ‘Filament jammed…’ error. This is in the non AMS mode and I have only one filament loaded. All AMS functions are unchecked. Can’t get past this situation.
