Title: In order to use F5 as Feed Hold, do I write a script?
Post by: MitchB on December 30, 2015, 07:53:17 PM

Before I delve into this, I wanted to see if there's a simple way to assign Feed Hold to a keyboard key.  Thanks.

Hit the space bar.

That worked for me in Mach 3.  Not in Mach 4.

Sorry, I didn't see it was Mach4.
What about the keyboard plugin?

I don't see a Feed Hold function that I can assign to a key.  I don't know if that means I need to write one or if it is somewhere that I don't see it.  I see only functions for jogging.

The keyboard plugin is for inputs and feedhold is an output.

You could assign a function of none in the plugin and tie this to an input, then in your plc you can activate the feedhold when this input state is changed.

Any chance there are step by step instructions somewhere describing how to do that?

Wow.  That's great.  I'm looking forward to trying it.  Thanks a lot.

Is there a reason you put this in the PLC script instead of the Signal script?

No reason they both do the same thing,

the other way to do it is as a signal table, it work's the same as what Daz said to do

Code: [Select]

SignalTable = {001,
    [mc.ISIG_INPUT0] = function (on_off)
        if (on_off == 1) then
            mc.mcCntlCycleStart(inst)
        end
    end
}
SignalTable = {002,
    [mc.ISIG_INPUT1] = function (on_off)
        if (on_off == 1) then
            mc.mcCntlCycleStop(inst)
        end
    end
}
SignalTable = {003,
    [mc.ISIG_INPUT2] = function (on_off)
        if (on_off == 1) then
            mc.mcCntlReset(inst)
        end
    end
}
SignalTable = {004,
    [mc.ISIG_INPUT3] = function (on_off)
        if (on_off == 1) then
            mc.mcCntlFeedHold(inst)
        end
    end
}

Two Lua questions about your example:

1. Are these table constructors redeclaring SignalTable each time?  Shouldn't all the keys and functions be in one SignalTable?
2. What are the 001, 002, etc. for?
