A1 not extruding / Clicking

  1. Yes, I disassembled the print head, right back to the gears, blew it out, “yellow” wheel moves and the gear it hits also moves well.
  2. Question. The filament comes down into the extruder and runs between the small black wheel on left (no gears) and the black wheel on the larger yellow gear . Yes?
  3. Would the screw being loose cause this? The screw that pushes the spring in? and could filament buildup on the black roller cause this because loading / offloading the filaments on the AMS unit works fine and the former colors are extruded etc

    And as a side note, when I took the textured plate off I notices I only have 3/4 screrws affixing it to the heatbed, the 4th was started with a tap but stopped, will have to start a ticket for that I suppose

My a1 and a1 mini printer makes a clicking noise when its trying to extrude filliment but the nozzle isn’t how enough
