Yes, the limit switch can be set up to also be taken as the
home switch. But, you need

You need an IEEE 1284 cable. (then

Unless I am understanding this wrong, I figured an axis

you can also look for a "db25 extension cable" those are straight
through. they typically come F-M, but you can use a gender changer
at either end if needed
(but I have seen them FF MM FM) and are inexpensive.

Here's one from element14:
looks like you'd need a db25 straight through.
A null modem cable has certain wires hard wired (typical to ground), you
probably don't want that.

I am in new zealand and don't really want to buy a cable from america as

yes, pretty much. since if I use it as a "homing device", it won't go
past there anyway.
So yes, I think that is what I'd want it to do, use it as home input

In the case of the lathe it's pretty easy if you have the following config
wich is the one I'm using:

I think the question you’re asking is how to use the limit switch as a home
input. On my bridgeport mill, a single limit switch trips on the min and max
limits. I also use this for home. I do this by assigning the same hardware
pin to axis.0.home-sw-in (or axis.1, axis.2, etc)

Hello Ron,

any soft limit (hardware limit). Whenever a limit switch is triggered the

I am trying to configure the limit switches in linuxcnc, I think I can

The switches get tripped, when teh cross slide is as close to the chuck
