How to clear toolhead clog

Sovol Zero
1

NEW Sovol Zero..after printing about 9hours, toolhead clogged

Tried pushing needle from nozzle upwards, could feel a solid wall clog (350C)

Rod(with loop) can not go down from extruder(350C)

Any idea how to clear clog with dismantling the toolhead?

Thanks in advance

@LochNess I had a similar problem when I first got my printer. I was experimenting with the nozzle temps and completely clogged the cold and hot ends by repeatedly preheating the printhead. I found and used this tool to push from the top down, does really well, the filament slowly extruded from the bottom as I pushed the rod down like it was naturally feeding from the extrusion drive.

When nozzle clogging occurred on my Zero I used these steps:

  1. Preheat to current filament temperature, for one of my clogs I had PLA that was stubborn and had to heat for the next filament type PETG. Generally the current filament type works.
  2. Remove the print head blue cover.
  3. Undo the thumb screw for the for Extrusion Drive.
  4. After the print head is fully heated, If any filament remains above the entry hole, pull the filament up from the top so it separates.
  5. Use the 1.50mm rod to slowly push any remaining filament from the cold end through the hot end of the nozzle.
  6. I let the printhead cool to room temperature, I normally turn off the printer.
  7. I then turn on the printer and begin the process to load filament.

So far the above steps have worked for me on my Zero when I hit the really bad clogs, not often now, but in the beginning I was learning about the 3d printing world.
