Progress on Large CNC Router Stepper Drivers

Had some time tonight to solder together the stepper drivers for the Large Format CNC router. All components are now soldered except for the power transistors which I need to layout on the heatsink in a way that duplicates how the drivers will be mounted in the chasis so that the locations all work  out correctly.

Stepper driver less the PIC and the power transistors.
