so far bought a spindle motor and the axis stepper drivers. Its not inverter duty but Im going to try it, since its larger HP my hope is it will not have temp issues. Have the VFD identified but its common so no hurry. Im going to Ebay the Emco drivers to raise money for the retrofit, I also have the transformer to sell. Im modelling the control to fit in a commercial wall cabinet, should have pics soon of the 3D models.
