Re: [CAD_CAM_EDM_DRO] Gantry Drive Topology

My parents own a picture framing shop and they purchased a CNC mat
cutter a few years ago. http://www.wizardint.com/matcutter.asp the
design was a real eye opener! Although it would never work for any type
of spindle work, or torch work, but the gantry has about 3'X6' of
movement and what would be the Z is actually a rotating knife blade.
The frame is extruded aluminum and the drive system is a white colored
toothed belt that runs inside of the T-slots of the frame, But the neat
thing is that the linear guide system is made up of these little
plastic poly wheels that where designed to roll along the T-slot notch
of the aluminum frame. extremely simple design.
