After reading everything I could find, including a lot of CNC Zone, I decided to build a DIY CNC Machine. I used the free plans from ModularCNC, and slowly made my through the cut-out and build. Most of the machine is made with 3/4" MDF.
And here are a few test cuts...
I am writing my build up in a blog, slowly adding everything I have done...only a little there so far, but more pictures and write-up to follow. Here is the link to the BLOG.
The build was a lot of fun...and frustrating.
I am using NEMA 17 Stepper motors, 75oz/in, the Univelop 3-axis Stepper motor driver board, and a 20v 6 amp power supply.
I have about 12" x 12" x 3.5" cutting area.
