Okay some of you may have seen a picture of my old version. It worked, I cut some wood, some aluminum, and acrylic but it lacked stability. The cutouts at the front caused the frame to flex under high stress and/or speed causing my cuts to be out of line.
I just happened to have laying around a giant box made from bosch extruded aluminum (it was borrowed from previous employer when I left). The box was originally going to be a giant terrarium coffee table but the wifey was not happy about the idea and it did seem like a lot of work. Anyways it looked like a good replacement frame. Well it ended up about one inch to short in the X direction so I ended up with a compromised hybrid.
It is unbelievably stable now. I have yet to attach the spindle motor yet because I am changing from the dremel to a cutoff saw thing which will increase my cutting power exponentially.
Another drawback to cutting was excessive heat so this version has a pump to squirt liquid at the bit when cutting.
Also new will be limit switches which I had before but never hooked up, this should allow a stable home position and allow repeated work as opposed to one offs.
