  I have put this project on hold for awhile. I have not had time to work on it, and I have since purchased an Anet A8 printer. I may consider re-purposing this project as a CNC mill or laser cutter/engraver.

  I have scavenged several parts from many different models of printers and scanners over the years. I will outline some of the parts I will be using for my 3D printer build.
  

  To start with, I was very fortunate to get my hands on a Microtek TMA 1600 transfer add-on for a 9800XL scanner. This is a large format scanner which had a stepper motor, belt, gear reduction assembly, 2 10mm rods, and various control boards (which I will not be using). You can see the stepper motor below and I have uploaded datasheets to the project page.
  

  I also have parts from a Lexmark Pinnacle Pro 901 AIO printer, several hp printers, brother printers, and a couple of flat bed scanners in letter and legal format that I don't remember the brand.

  As you can see in the picture, there are several useful parts to work with. The 2 10mm rods are on the right. The rest I believe are 8mm. Since some of the motors have gear reductions, I want to test the step length to see what kind of resolution I will get out of them. I will be using an Arduino Uno with a Seeed Studios motor shield v2.2 for testing.

  I had some pre-cut slats of 3/4" Plywood handy so to test the Teco motor from the MicroTek, I just bolted the motor mount assembly to the end of the slat. At this stage I don't need a whole lot of accuracy in placement, but I did verify that one edge was straight, and the corners are square. These slats were factory cut so that was easy.

  On the other end of the test rig I used the tensioner roller from the scanner. The tension uses a screw that passes through the internal frame of the scanner. I drilled a couple of holes in a piece of the frame to use a a bracket for tensioning which is at the right of the rig.

  So far, that's it. More to come.
