Tom,

So you are killing the AC power when you hit e-stop.  If you are using the C23 and have enabled the Safety Charge Pump, you can use pin 17 for that. This should not blow the fuse.  Have you talked to Larry?  I am sure he can suggest something.  This sounds like a problem with the power supply.

On large machines I always recommend users to not leave the limits and e-stop at software control.  Our boards come with an external enable terminal marked EN.  You can use that to connect e-stop and limits to have these disable the outputs and stop the machine at hardware level.

Steven,

I see you have received already all the ideas of possible ways to do it that I can think off. If I remember your setup, you still have an electromechanical relay available on the C11.  Te fastest way of doing this, could be to configure an output like was described on previous posts.

If you want to get fancy, you can edit the M30 macro to activate signal.  Keep in mind you may have to create a button to disable the alarm once you get to the machine.

General Mach Discussion / Re: Output Pin Problem

Dear Sir,

Someone brought this message to my attention (thanks).  You mentioned you were waiting for an answer from me, sorry, but I am not aware of this, when and how you tried to contact me?
So it is just outputs 1 and 16 and the Safety Charge Pump  that are not working? Please check the following:

-   Are the LEDs for pins 1, 16, and 17 on the board lighting?
-   What about the LEDs in the diagnostics screen in mach3?
-   Have you tried a different cable?
-   Could you measure those output pins with a multimeter? In the port itself, the cable, and terminals on the board?

If you are positive the board is receiving the signals, then it must be that one of the buffers or optoisolators could have gotten damaged.  I know how frustrating this is, but keep in mind that it is better to have to replace this than to have to deal with a problem with the PC.  These chips are easy to replace, inexpensive, and readily available: http://www.cnc4pc.com/Store/osc/index.php?cPath=38_43.

Please let me know how it goes.

Thanks,

Simon,

Please send me a copy of your xml file, I will test it on my SS.

Simon,

Sorry, I do not get it, it should work exactly the same way.  Is the C11G receiving the signals? What is the status of the LEDs?

Simon,

There are two ways of implementing the spindle direction, and it depends on the speed controller you are using:

1. If you have a VFD, you could use the electromechanical relay to change between the CW and CCW of the VFD. You would activate this with the spindle direction pin.
2. If you had a C23, C11, or C6, which come with two independent relays; one could be used for CW and the other one for CCW. You would activate this with by assigning the two relays under config/Ports&Pins/Spindle/ Relays.
3. If your speed controller did not have a direction input, and was DC based, you could use the two relays to reverse the winding of the motor.  You have to be careful to allow for a delay before changing directions and watching not to exceed the rated amperage of the relays.

Simon,

We apreciate if you can test the new plug-in.

Derek,

I am sorry you are having this problem.  You never contacted me with inquiry about this.

What is the part number of the sensor you are using?  I believe it could have an open collector connection, so it requires a pull-up resistor to work with the inputs of the C11.  Are you using a pull-up resistor?

If the sensor has +5vdc output, then the value of the pull-up should be something around 100 to 150 ohms.

Please let me know how it goes.

Do you see in the MPG window? when you press tab? do you see it changing?
