I have installed V6 hotend (all metal) with a direct drive extruder on Ender 3. It flows alright when I push manually however, the print is severely under extruded and doesn't stick to the bed.

Things I have already tried:

  • Replaced the nozzle and the heat break however, the problem persists.
  • Tried changing the filament. PETG wrecked the heat break. PLA doesn't print either.
  • Reduced the retracing to 0.3 mm
  • Cleaning the bed.
