This is a reinforced ProtoXtruder 2.0 designed as a bolt-on upgrade for the original ProtoXtruder 2.0! It's designed to survive the stress of high-temperature heated chambers, and is designed to jam less.
Here's a list of improvements compared to the original ProtoXtruder 2.0!
Greatly reinforced with more plastic to prevent deforming under high-temperature heated chambers (60C+). Extruders are already under a lot of stress, and putting them in high heat from a heated chamber, plus the added heat of being against the stepper motor and near the hot end, makes ASA more pliable. The first gear's bearing mounts are especially susceptible to deformations. In my experience, after about 20 prints with the original extruder in a 65C heated chamber, the bearings become loose and the print quality suffers. This improved model makes every area that handles stress stronger, and is suitable for long-term use in a hot heated chamber.
Idler arm closes the extruder teeth an additional 1 mm to prevent jams from hot, soft filament. When printing in a hot heated chamber (65C+), air-cooled heat breaks get quite a bit hotter than when printing in ambient temperature, therefore the filament gets hotter and softer. With the original design, it is possible for the filament teeth to wear notches in the soft filament, which makes the teeth slip, and results in failed prints. With 1 mm more clamping distance, soft filament remains gripped even when deformed, and prints succeed when they would otherwise jam.
More appropriate self-tapping idler arm screw size and idler pivot hole sizes. On the original ProtoXtruder 2.0, the self-tapping idler arm screw hole is much too large, and it is very easy to strip. This model reduces the self-tapping hole from 2.9 mm to 2.6 mm for a confident thread tap. Additionally, the idler arm's pivot hole was widened from 1.6 mm to 1.75 mm to prevent the arm from jamming on the screw.
