Goal 1: Rewiring

General Shapeoko Device Cables.jpg

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.

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.
