Very good Gerald. I have a friend that sent me a link to your site a couple of weeks ago that is planning on building one. I liked it then and I like it now. Do you know if anyone is using this for a Plasma?

In the works.

Gerald,
Outstanding design.  Thanks for posting the drawings. 
Question about the rails.  Is there any restraint in the pluz Z axis for the gantry on the X rails.   Does the design rely on gravity to hold the gantry from riding up in the vertical?   I'm guessing yes, from looking at the plans and estimating the weight of the gantry.   Same goes for the Y-Z gantry? 
Thanks,
Dave

Thanks for the encouragement Dave.

Gravity does help but doesn't do it all. The motor pinions ride racks under the rails and the motors are spring-tensioned against the racks to pull the cars down and to eliminate backlash at the rack/pinion interface. The one side of the y-car that has no motor still has a spring and idler roller running under the rail.
