Michael,

If you are interested in building your own pro like CNC machine, go absolutly to www.mechmate.com.
My Mechmate is a 2800mm x 2070mm x 100mm.
I'm sure the CNC users community are going to use more and more MOI : i have presented MOI to the Mechmate community.
With some small added features like orient tool, it will be perfect ....

bye,

Pierre.

PS : Nice job lemo.
