Hi Les
If your selling machines you have to be super extra careful and try and make
them idiot

Hi Len,
Sorry if I came on a bit strong there but I do a lot of repairs on CNC
machines. I have seen what happens when things go wrong and it isn't
pretty. If you are selling these machines I would still be carefule with
the EStops just in case.
Apart from that rant, this is an interesting thr

Yeah - I get that. But these machines are tiny little desktop routers. We

Hi Len,
Never rely on a computer for EStop or limits. Your EStop and limit
switches should all be part of a chain of switches that directly kill
the supply. The computer should obviously be notified that an EStop has
occurred but it should not be able to prevent an EStop. In the case of

Oops, sorry. Your last email came in as I was responding.

Thanks for bringing this up.
EMC has provisions for soft limits set in the ini file, hard limit
switches (some of mine also
serve as Home switches) and E(mergency)-Stop switches.
My E-stop switches (big Allen-Bradley N.O. buttons with guards) are
tied to the estop input
pin and a relay to kill pow

e-stop
e-stop would be manual switches. Not limit switches.

If you're looking for two inputs to stop EMC2, you can easily do that
with an "or" component (or "and" if you're using negative logic).
A better way to do it is to use an input as active low, an
for the plus and minus limits?

Why do you need them on different pins?
You could wire two NO switches in parallel or two NC switches in series.
Each set would be handled by a single pin.

How do I configure hal to handle two e-stop switches on two different pins?
