Searching some Junk drives and found these 2. First one is Coogara's with permission second was open source Google if I remember right(sorry I can't remember to credit). Neither does what I want exactly. Anybody drilled and tapped the aluminum frame(see a couple of wires on Y to watch out for, but not seeing Anything on X axis) and bolted something flush to aluminum extrusions that can in turn be drilled and tapped for adjustable wood X,Y fences?
