Oh Noooo!!!!! Somewhere around layer 170 one of the belts came loose! I'm going to have to come up with a more secure clamp. Once I get the belts fixed I'll be ready to try again. For now I'm trying to use up the ink in a new cartridge. I tried to refill an old one with the water/vodka mix but it was hopelessly clogged. I figure I'll have better luck with a new one. For now I'll keep working on getting the powder layer as smooth as possible. I also need to install a limit switch on the supply bin so it stops when it reaches the top.

Lather, Rinse, Repeat
Well I filled it with powder and took it for a test drive. The first thing I noticed was that I needed to add something to keep the powder from spilling over the sides of the bins as it was being rolled out. I'm still tinkering with the roller speed trying to get the smoothest layer possible. (I think the problem may be partly with my plaster formula) Anyway it was good enough to run some tests.
The print and recharge cycles run great. (Sorry for the really awful video) I am using Paulo Cesar's Project 1 (available at the Yahoo DIY 3D Printing and Fabrication group) to slice my stl files. Many thanks to Paulo for a slicer utility that is easy to use and doesn't require me to know how to script or program.
