Plasma Touch Sensor Configuration for UCCNC with Macro

Wiring a single NPN sensor.

Wiring multiple NPN sensors in series.

General Recommendations on Setting up Home/Limit Switches: 

1. Note that the Limit function is disabled while homing, so it is smart to use the same switches for homing and limits.  It is also a good practice to connect positive and negative signals to the same input, as the control software really cares only to know which axis the signal comes from, but the software knows in what direction the axis is moving.
2. Test with just one Switch.  Once set up for the switch is complete, proceed to the other switches which should go the same way as the first one.
3. When you wire the switch, test the switch and watch for action on the LED on the breakout board.  Use also the Diagnostics Screen to verify that the Motion Controller/Control Software is seeing action on the input signal.
4. Enable Homing and disable Limits for the axis you wired and test homing.  You may need to invert the active High/Low for the input
