JPN Extruder for CMYK+ colorprinting (SS) by jpnurro

The previous version of the concept got the massive rate of the interested. After sleeping over the night I thought the there is still many expensive components.
Here are two new concepts!
The drive has two options
1) normal gear pull but this makes the the unit wide, filament distance 23mm
2) pulling plates, like in the sewing machine, the filament distance 13 mm!!
The other new idea is to use the camshaft to manipulate filament feeding. Just rotating the cams and any combination is possible.
No more any sliding part nor high accuracy machinery needed.
The camshaft design is based on gray code binary mapping. This allows that only one filament feeding change happens at the time.
