Building a new extruder driver.

While I am reasonably happy with my initial prints I have decided to build Adrians geared extruder driver to improve the consistency of the extrusion.

The three photos show my new extruder driver.  Although the printed parts look good enough to work in this situation a close inspection of the print show the extrusion tends to “bead” a little and on some prints just stop altogether.  I’m hoping a driver with more “torque” will improve this as well as better spool management.  I’m also building a new extruder head as well to improve the temperature stability.

If anyone has other ideas on how to better improve the print quality of my reprap I’d love to hear about them.
