Hi Guy:
This wiring works on my setup, with a C10 board so it should work for you.
When you open the diagnostics page, no led's from your inputs should be lit. This is a
basic Mach3 rule.TheLED's light up when the switch goes "Active."
Wire the X, Y, or Z + limit up as folows.
On the end of the C10 board with the INPUT pins is a jumper for 1-2, Pull Down,
and 2-3 Pull Up. Put the jumper in the 2-3 position.
On the micro switch NO (Normally OPen) terminal, for the X + Limit switch, connect a Red
wire from the NO terminal to the C10 board input pin 15.
On the micro switch COM terminal for the X + Limit, connect a Black wire to the C10 board
GND terminal, or one of the COM terminals if the COM jumper is on the 1-2 position.
This jumper setting will make the COM terminals Ground.
Do not put the jumper in the 2-3 position, as that will make the COM terminals +5v
Go to Ports and Pins, Inputs, to the X++ line, and put a Green check under the Enable
column, for that action.
Under Port, put the number of the Port. It will be a 1, unless you are using a second
Port, with (2) C10 boards.
Put 15 in the Pin # column.
Put a Green check under the Active Low column.
Click on the Apply box, and the the OK box.
Open your Diagnostic page, and you will see the X++ box in the upper right is not lit.
Manually trip your X++ Limit switch, the the X++ box will turn Green.
Wire all of your Limit switches in the exact same way.
When all of your Limit switches are working correctly, go to the Config Menu, and scroll
to the last row, and click SAVE.
Regards,
John
