Mendel User Manual: Extruder

• Extruder jams with melted filament at the end of the brass barrel, starts to flow backwards.
  • Suggestion: Try and increase the temperature of the extruder heater. If the temperature is too low, not all the plastic can melt and only the plastic touching the barrel gets enough hot to melt and do a back flow.

• Final printed piece have a kind of displacement on XY axis, and when I see extruder going against ooze, then it gets that XY displacement.
  • Suggestion: Try to build the Spring_extruder, it automatically flexes when it goes against ooze or something blocking its path, and then it returns to where it should be. Alternatively, try increasing the current going through the steppers so it needs more force in order to slip.
