Tormach USB Expansion Board boxed and mounted

Another piece of the clock wheel cutting hardware completed.

The Tormach USB expansion board is now boxed and the connectors wired to the board.   I milled a viewing window in the box with a matching piece of perspex.   This allows me to see the status LEDs on the pcb. Port #P0 is now dedicated to the Sherline CNC rotary table controller which requires a closure to increment the table stepper motor.   

The connectors are all 8 pin MiniDIN which matches the interface on the rotary table.

Tormach USB Expansion card mounted in an IP55 enclosure and on the blanking panel where the ATC would normally be fitted.
Internal view of the Tormach USB Expansion board mounted in its enclosure. It shows the MiniDIN connectors on the pcb milled using my vacuum table and also the lazy cable gland on the USB cable

Still got to do the GCode …
