Cut and drilled last spacer. Marked (by printing a template) a drilled the Z-axis mount plate. Realized an earlier carriage spacer had holes that were not straight thru since the part was 2" thick and drill bit deviated as it cut, so I opened those 5.5mm holes to 8mm. Connected all Z-direction motion wiring. Used a power drill to coil the stepper motor lead wires (very cool). Also wired the VFD and spindle motor and did a quick test.
