Thank you Ron. Servo's is a strong consideration. Do you
know of a good source for the motors, or should I just look
around.

I have thought about driving the knee also, but I figured
the accuracy of the whole knee dovetail and the gears would not be
very accurate.

///Its very accurate. change elevations during a routine, check it and its there. The nice thing about using the knee is, Thats one part of the machine that isnt used much in the manual configuration so, it's usually in very good shape.///

I guess it is accurate enough for the Z axis
especially in light of the fact that the axis does not see a large
range of motion in most machining operations.

Can I ask you what kind of items you mostly machine?

////I design and build automation tooling and fixtures. Also general machine. Basically machine about everything. From toolsteels to rubber. ////

Thanks,

29 in-lb for X and Y. I did my retrofit with 40lb-in servos on all
three axies. Mach2 software, Bob Campbells breakout board and Gecko
320's. Its an excellent machine and I have been using it daily for
the last 19 months. No problems. There is pics of it on
the "CNCpics" group at yahoo under "rogersmach"
