Here is a little about me.

I am an electronic hobbyist from way back. I attended a 2 year vocational course in electronics in the early 80’s but my interest in electronics precedes even that. I worked in the industrial instrumentation field for 20 years. My current job is in management but I still run a home business repairing a proprietary PLC platform for industrial equipment.

My first exposure to a computer was a heathkit 200 running Benton Harbor Basic. This was the first language I learned to program in. My first personal computer was a Radio Shack Color Computer. I worked for Radio shack for 3 years by the way, doing computer installs, repair and sales.

I have migrated through many micro controller platforms. Some that I have used  are Basic Stamps, OOPIC, aTTiny, Phidgets, Cubeloc and now the Arduino. My largest build to date was a complete distributed I/O control system with over 300 I/O points and PC based supervisory control for a hazardous waste incinerator. My largest hobby build to date was an autonomous obstacle avoiding robot. It consisted of 2 micro controllers, 6 servos, infrared scanning and ranging, video feedback, sound activation and a lot of  fun learning. I have many other small builds from Internet SPA PH monitor to PC tablet based automotive integration. I have never done a very good job at recording my builds. The purpose of this Blog is to correct that in the future and hopefully build a network of friends to share experiences and knowledge with.

    Mark,
    Great page you have going here! Great project too!

    Unbelievably, I am working on the exact same thing (DIY 3 axis CNC controller) with the exact same hardware. You even built a protoboard version that looks remarkably similar to mine!

    I thought I would let you know that I just built a new board (pictures will be up later today or tomorrow) using the Allegro A4983 instead of the easy drivers and boy are they great. They run cooler, provide 16 x microstepping, and can push up to 2A per coil. I bought them for about $12 (fully assembled) from pololu (http://www.pololu.com/catalog/product/1201).

    Also, I’m using a program called grbl to run my machine. It lives on an arduino and does very well. IMHO, better than EMC2 or Mach. But again, that’s just my opinion.

    Anyhow, take a look at my page, and I’ll keep an eye on yours!

    Edward,
    That is cool that we are on such parallel paths. I will also check out both of your recommendations when I get back in town. Thanks for sharing.

    Do you have an email i can contact you on?

    Have a few questions to ask.

    Thanks

    Hey, I only learned how to machine recently, and my knowledge of electronics extends to only basic circuits. I must say, your projects are extremely impressive! I don’t even know how to operate a CNC and you’re building one yourself!
