Lots o Boards

The stepper controller boards arrived today.

Back Added

I added a back to this to increase the side-to-side stability. It helped but not as much as I would have liked. Next up is adding motor controller board. The back can also serve as a mounting place to keep the PCBs out of reach when you are handling the bot.

Electronics Melted

I have the motherboard working. I had 1 motor controller working. It melted. I saw silicon glowing red hot, and one of the pins melt. There was a lot of stinky black smoke in my bedroom. Not sure if the device was bad, the soldering job was bad or the motherboard was bad. It was the 12V supply that melted down. I need mother motor controller boards.
Here are some improvements that could be applied to the electronics:
-a fuse or some over current protection mechanism

Well this gave me a chance to improve upon the Green Monster's body; I am adding a back wall. The electronics will be safely hidden behind the wall.
