You can follow my work on whosawhatsis.com or on twitter. I also post my designs on thingiverse.

Most of my Reprap work has been on Huxley, but I'm also working on some ideas for hot end and extruder drive improvements.

Oversized Huxley

I've built an oversized Huxley by cutting the rods and belts longer to make it almost as big as Mendel. The build platform is 8"x8" (about 195x195mm usable), but the outside is only 15"x14"x13".

I've had a lot of trouble getting reliable extrusion, and I've taken the bowden cable out of the equation (at least temporarily) and have been working with carriage-mounted extruders. This seems to work fine with the NEMA 14 motors I bought, which meet the 13.7 N-cm torque requirement for Mendel. The picture is an old one, before the pulley extenders and the other modifications I made to get it working. I'll post a new one when I get the extruder put back together with the new motor I ordered.

I've made a few updates to the design (not pictured, this is my first printer so I had to work with the printed parts I had):
