    This is my home made DIY CNC and so far I’m very happy with it.. this is its first run.
    - Steppers Nema 17. 12V
    - Threaded rod and nuts (works OK but will need to make anti back lash nuts)
    - Controller: 3 Axis TB6560 Stepper Motor Driver from Qualitygadgets on ebay (I must say they were fast shipping and it all works well! so I’m giving them a bump here – https://stores.ebay.com/qualitygadgets )

    Over all its been very fun to build, most has just been from designs and ideas in my head along with allot of reading and research on CNCZone.com and other sites.

    Now comes the fun and excitement of making use of it and learning more about Mach3 and LinuxCNC, woooohoooo good times!

    The Video was taken at GeekSunday an event my wife and I hold each month here in San Jose CA

    Thanks to Christopher Tuck and Brenda Make for all their help!
