I'm very new here and I have a very small router ready for the electrical part of the build process to begin.I have used a number of industrial CNC routers which all used proximity sensors for determining the home position of the axes.They seem to be fairly inexpensive items and I have seen how consistent they can be.What does it take to connect them to a breakout board and would I have to create a homing routine for use with LinuxCNC? Come to that,should I ask the question on that Forum?
I used those type for home position, the drawing shows how they were connected.
3 wire type working from 24v DC
This is the mounting arrangement, you want the striker to move past them, not up against them.

Hi and welcome to the forum it depends on how you are going to connect to Linuxcnc ie. via a PP or with a 5i25 and 7176 bob but those sensors are very popular if going with the 7i76 bob then pnp type are the best but npn type are still ok but need pull up;sQuote:

No prob. start here http://linuxcnc.org/docs/2.7/html/ge...-linuxcnc.html latest version is 2.7.11Quote:

If you have two screws and one motor then go for 2.7.11
