I've been a fan of MakerSlide ever since building my ShapeOko CNC Mill, and have been interested in 3D printing since first hearing about the RepRap project in 2007. So when I first saw the OrdBot, I knew that it would be the printer I build. It didn't hurt that I had 10 feet of extra MakerSlide and a whole bunch of the special bearings and eccentric spacers left over from my ShapeOko build.
One of my goals was to build all the custom parts myself, the blue and black pieces in the photo above. Cutting aluminum on my new CNC machine pushed it to the limit, but worked out in the end. One of the larger OrdBot pieces is the handle, here is a shot of the ShapeOko making short work of it:
There are a couple parts that I modified or upgraded during the build. Most notably the Z axis. After reading about bent Z-rods I decided to get some ACME rods, and I wanted to use some spare Nema-23 motors that I had on hand.
The NEMA-23 motors for the Z axis were easy, I slightly modified the stock motor part to fit the new motor:
Attaching the ACME rod was a little trickier, but managed to hand fabricate a bracket with some 1/8" thick angle aluminum:
In the spirit of being thrifty, I signed up for one of the (now notorious) Qu-bd extruders during their kickstarter campaign. So far I've managed to get the extruder to work with a couple of simple motifications. Some more hand fabricated mounts and I had the extruder attached:
For the electronics I am using one of the first generation Azteeg X1 boards. So far I've been very happy with it (save for an exciting wiring mistake where I had the polarity backwards). I opted to run the wires through the hollow MakerSlide extrusions whenever possible. Here is the nearly completed wiring, I really appreciated the zip-tie holes:
After a few days of tweaking and calibrating, I'm getting some nice results. Here are some action shots with the machine up and running:
