UP! extruder modification 2, pressure arm
Description
UP! extruder Mofification 1. Tolerant to material variances 2. Stable mounting My best modification to the extruder has developed into; • Replace "pressure" block holding "fixed position" feed roller bearing that applies pressure to keep filament in contact with extruder gear with new design 2 part adjustable constant pressure block and arm incorporating "Vlier" spring plunger to apply consistent pressure regardless of variances in filament diameter tolerances.
