PASTE EXTRUDER / STEPPER MOTOR DRIVEN

Dear Makers

here are my files for a stepper motor driven Paste Extruder.
It is a drivative of the simple paste extruder by "keesj". I used this thing in my delta-printer

The speed of the stepper motor is controlled manually using arduino, an easydriver V4.2 and a potentiometer.

the thing is finished ... but the preparation of the right paste is a work in progress as you might see in the short video ;)
