My 3D printer had its first test run last night. So far I need to replace the X axis stepper motor it has a bad connection inside of it somewhere as can be seen in this video on Youtube.
Here is a picture of the jumpers to convert the Ramps board to a printer 25 pin interface. I only connected to the pins that I needed for X, Y, and Z for Step, Direction and Enable, they are blue, green and yellow. The enables are all connected to ground. Then I also needed to connect to ground and 5 Volts, they are yellow and red, the top two connections..
Here is another video of the DIY 3D printer this time it is running with and Arduino Mega.
Here is a picture of the Ramps wiring. The heat bed is not wired up yet.
Here is the wiring with the heat bed wires in. I spliced the ribbon cable into some 14 gauge stranded cable and covered the splice with heat shrink.
Here is the third video. This was my first extrusion attempt.
Here is what I got from my first attempt at making something. It was supposed to be a 8mm bearing support.
