I have purchased a used cnc router and am about to instal limit switches. The machine is running Mach3. I have read the "hot topic" posting on limit switches and believe I have it figured out but would like some confirmation that it is correct. This machine has a ST-V3 board and I was able to locate a diagram on it to identify which pin is what. I am also waiting on two E-Stop buttons and want to install these as well. My plan is to put these in series all through one pin (pin10) and return to the ground pin, then use pin 13 for the e-stop button. I am also under the impression I will be able to use these switches as homing switches and soft limits.
Here is a photo of the board that is with the system:
here is the diagram I found that identifies the pins:
Here is a crude diagram of my plan on wiring this up:
My questions are, does this look correct? Is there a different / better way? My hope is to add future items to the machine such as spindle speed and a touch off plate.
Any help is greatly appreciated!
