My machine is based on a XZero Raptor (48"x30"), 6" clearance under gantry, but 12" z travel.
As mentioned, i using an Mach3, an ESS controller, Leadshine 4660 drive and Leadshine 57HS22 motors.
Spindle is a 2.2kW Tekno (electric fan cooled version) with a Delta VFD.
Here are the schematics for my machine.
I probably would do some things a little different now, but we started with the 3660 and the machine has evolved as we have used it.
Ill post a couple pic of the electrical cabinet and machine later.
