The example below shows pin 15 being used, but if you are already using pin 15 for something else (such as a limit switch or estop), you will need to use another available input. You will need to configure the probe as an active low input on an available open input. NOTE, the V- connection should be the lead connected to the magnet (or clip on older models), while the input pin should be the lead going to the brass puck on the touch plate./li> For a G540 based system, you will need to wire one of the leads to an available input (pins 1 through 4 on the G540), and the other lead to the G540 power supply common (V-, on pin 12 of the G540).For a DIY system based on the PMDX-126 breakout board, just connect the two leads to an input pin and a common on J11.NOTE, the 'Ground' should be the lead connected to the magnet (or clip on older models), while the 'Signal' should be the lead going to the brass puck on the touch plate. For older PMDX-126 based NEMA 34 systems, just connect the two leads on the unit to “Signal” and “Ground” on one of the 3 pin connectors supplied with your panel, and plug into the red input signal board.In either case, you can use a different AUX port if you prefer, although you will then need to re-assign the pin used for the 'Probe' function.For earlier revisions of our XML configuration files, use the 'Z' sensor input (Port #2, Pin #6).For our revision 16.1 - 18.3 configuration files, use the 'Aux 1' sensor input (Port #2, Pin #9).

For our revision 19.2 configuration files, use the 'Aux 2' sensor input (Port #2, Pin #8).For our CRP800 Plug and Play CNC Control Systems (both NEMA 23 and NEMA 34), just plug the M12 connector from your touch plate into the appropriate input for configuration file your are using:.Setup of the Auto Z and Corner Finding Touch Plate is fairly straight forward: Using the Auto Z and Corner Finding Touch Plate with Mach3
