Goal 1: Rewiring

Note: The Spindle Power cable has a modification. The end connector is not common. So, a new connector has be added as a matched pair with screw terminal. The use of screw terminal connectors makes "cutting" of wiring less likely and allows reuse of connectors. The connectors do not require soldering and allow for rewiring without need to "get" new connectors or "solder" lines. A lot of wiring repairs have inline splices that cause later difficulties. The screw terminals would allow entire wiring replacement.

Goal 2: Electronics

Three Boards - Arduino Uno, Arduino Prototyping Shield, CNC Shield V3.0

Notes: The Arduino has its power jack removed. The Arduino is powered thru the USB. The circuitry on the Prototyping Shield added noise filtering and debounce protection to the Limit Switch Lines and Control Buttons on the E-Stop pendant. The circuitry in the photo was modified according to the schematic below to improve debounce behavior.

The electronic were assembled in the stack below.

Goal 2: Controller Box Assembly

The electronic, wiring and cooling fans were organized and supported by custom 3D printed parts.
