Any thoughts on this design from all you guru's ?
Will be using Mechmate home ground rails for x and y. The results some of those guys get are amazing (see mechmates forum for some amazing router builds) . rack and pinion of x and y. Will have a water table that can be wheeled in and out. Would also like to use it ocasionally as a router, I appreciate that there will be a fair amount of set up time to convert between the two. Will be using a gear a belt reduction on all axis approx 3:1.

Havent even thought about z yet but it will have THC. Any thoughts here would be greatfully received.

I have a candcnc plas pak 1a kit. Want to have it running by end of december latest.

All advice much appreciated.

I don't remember the MechMate final drive design but a real popular and functional R & P final drive is to mount the rack teeth down and pull the pinion into the teeth with a spring or air cylinder. That provides optimum mesh and lowers backlash. It requires the pinion and motor swivel as a unit and a dual drive gantry offers the easiest way to make each side independently adjustable.
