Why is my filament snapping inside the Bowden Tube?
Answer: Filament possibly low quality, or not dry. Consider making a filament dryer from our Filament Drying page, buy a ready-made one. Check the diameter of your filament for consistency using Calipers. Buy good quality filament with strong reviews.

My Extruder is pushing but no Filament is coming out of the Hot End?
Answer: This can be a blocked hot end, or incorrect tension set on the extruder tension handle. Check the Extruder Setup & Calibration page first to ensure the Extruder is set correctly. If its still happening, you may need to clean out your hot end. Consider buying a 3D printer maintenance kit with 0.4mm needles included. You may need to do a Cold Pull (Guide Coming Soon) or Disassemble your Hot End for Cleaning.
