well.. motors were taken out of broken old harddrives, ~0$ fishing line .. ~ .5$ metal base was some scrap I had around .. ~2$ the L-shaped holders, also scrap .. ~1$ I used MIG nozzles to feed the fishing line .. ~2$ each stepper drivers .. ~20$ to build from scratch each (I actually had the ones in the pic from a friend, and gave them back) PC + emc2 .. ~ 1 week to set up (should be way faster now, as the config is included in emc2) I appreciate the whole thing to have cost me about 10-20$ + time to set it up (an afternoon). > Your particular prototype would be good for use as a rapid prototyping > framework for reprap if you have a method > for obtaining a z axis. it actually does have an Z axis, which I don't use. In order to use the Z axis, you need to have some weight on the tooltip, and let gravity do it's thing. But for that I would have needed bigger motors, maybe a future version will have that.
