Mock-up of my Surplus Gizmos Black Friday 3D printer. I managed to get the linear bearing mounted on a steal 1/2" plate along with a NEMA23 stepper motor (0.3 Ohm windings), 3 opto-couplers, belt and pulley, and cable chain. All of this for just $25!!! The extruded aluminum and aluminum base plate cost me another $55.
The X and Z axes will be from a Prusa i3, since I was printing out parts to build one already. I just couldn't pass up the deal. When all is done, it should have a build area of 8.5"W x 12"D x 12"H. A nice upgrade from my cupcake (3.8"W x 4"D x 4"H) and hopefully more reliable.
If I can get my cupcake to stop failing on me long enough to print the last two parts I need, I should have this ready to print in another week or so. Eventually I will get an aluminum plate made, but for now, I'll just have to hobble along with a plastic one. For the price, I can't be too picky. :)
