I hook up the micro switch for limits on X axis to P11 & GND and it does nothing when the switch is activated.

This switch must be using the Normally Open (N.O.) contacts and the Mach3 Input related to pin 11 must be configured as Active Low.

(The other switches are then configured in a similar manner).

Hi,
have you assigned on Config/Ports and Pins/Input Signals X++, X--, Y++ etc?

Your post suggests that you are going to have one circuit for each axis, so you will need to enable X++ and assign to pin 11 port1,
X-- must be enabled and assigned to the same pin, ie pin 11 port 1.

You should now with a small piece of wire short pin 11 to either 0V or 12V of the input pin powersupply and see the limit switch LED
on the diagnostics screen light up. Whether it lights up when pin 11 is shorted to 0V or 12V will depend on the 'active low' assignment
you've made on Config/Ports and Pins/Input Signals page.
