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.

Re: [Emc-users] two e-stop switches
The standard way is to wire the switches in series using the n/c contact. So I assume you have some valid reason for wanting to do it with two inputs... like your machine is so huge you need to know which switch is in the stop condition. What you need is to "or" the inputs using the or2 component if you use the N/O contacts. First you have to "load" an or2 in your hal file with: loadrt or2 Now when you look in your Show HAL Configuration screen under Pins you will see an or2 has been loaded. You will then see that your or2 has two inputs and one output. First you "connect the or2 out to the line where the single e-stop was connected (if you used stepconf wizard) it will be: net estop-ext <= parport.0.pin-10-in change to net estop-ext <= or2.0.out You need to connect the two inputs to your physical inputs with net. Lets say you used pin 10 and 11 of the parallel port to bring your signals in... then connect the pins to the or2 in's like so: net estop1 or2.0.in0 <== parport.0.pin-10-in net estop2 or2.0.in0 <== parport.0.pin-11-in This has not been tested but AFAIK it is correct... The other option which would be better is to use is the and2 component and the N/C contacts. It will be similar to the above... this should get you started and now I have to write an example for the manual... John On 2 Dec 2008 at 17:01, Jack Coats wrote: > e-stop would be manual switches.

Re: [Emc-users] two e-stop switches
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 limits you need some way of overriding them, preferably by a pushbutton switch rather than under software control. This is a basic safety requirement and should not be ignored. Computers and software are simply not reliable enough for safety critical functions like this. If something goes wrong with the computer or EMC crashes and causes a runaway you want to be able to stop it.

Re: [Emc-users] two e-stop switches
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 power to the motors. They are for emergency only.

Sorry - let me rephrase the question... Forget about the fact that it's an e-stop. I want to be able to use switches on a pendent to perform the same functions as some of the axis screen buttons.

A better way to do it is to use an input as active low, and wire the two switches in series. This will allow you to physically disable the machine from one connection as well. This is the most common practice, to wire all things that can cause an e-stop in series (the e-stop chain), and feed that to the machine disabling hardware (which then optionally informs EMC2 that the machine is off and it can stop now :) ). - Steve - This SF.Net email is sponsored by the Moblin Your Move Developer's challenge Build the coolest Linux based applications with Moblin SDK & win great prizes Grand prize is a trip for two to an Open Source event anywhere in the world http://moblin-contest.org/redirect.php?banner_id=100&url=/ ___ Emc-users mailing list Emc-users@lists.sourceforge.net https://lists.sourceforge.net/lists/listinfo/emc-users

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.
