UP! extruder Mofification
- Tolerant to material variances
- Stable mounting
My best modification to the extruder has developed into;
â€¢ 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.
This needs to be made from machined aluminum or steel, I printed it once to confirm "Form and Fit" but for Function it needs to be metal.
