3D Printer Progress — Garage Style

I won’t go through the instructions on how to build a 3D printer. They can be found pretty much everywhere online. What I will do is show the progress that has been made so far with my garage printer. The first thing is this is a Wolf / Gantry style 3D printer.   I made

So you need a cheap 40 Amp 12V supply?

Coming up this summer I will be building a 3D printer. Did you know that they draw a little bit of juice? Well just so happens that I had a Dell Power Edge 2650 laying in the basement of my house. Now you may not have one but you can get the power supplies off of E-Bay

Obstacle Avoidance – Self Guided

One of the unique things that was learned from the Arduino Rover, was the design of basic avoidance routines. The routines are almost always unique to the platform. This is true even if using multiple RC cars. The RC cars drives will respond and handle differently based on a number of basic factors to include traction,

Mars Rover Autopsy

After having built the RC Rover based on a cheap New Bright RC I would make these recommendations. The Arduino tie in portion was easy, I would use two PING sensors so it can actually detect a cross section of an area. This would allow it to negotiate crowded areas better. The drive wheels stripped
