Simple... Plasma application question
« on: May 02, 2010, 07:35:58 PM »
Hello all,

Long time, no post... I hope everyone is well.
I have a possibly ridiculous question:
I'm messing with my PIC controlled THC and I can't get my head around one thing...
Is there an "Enable THC" output from Mach, and if so, which output is it (by default)?
Is it "Set OUTPUT5 when in THC" on "Ports and Pins" page, "Mill Options" tab?
Will this output act as the THC inhibit in regards to the anti-dive feature?
Any help on my foggy questions would be greatly appreciated.

Thanks all,
Chris

Yes I think so - certainly if you set this up it gets toggled with the THC on/off button (OEM code 123). That said some THCs don't neccessarily use it - my THC300 for example has no specific enable. It's just that Mach ignores any up/down signal from the THC if the enable button is off.


Will this output act as the THC inhibit in regards to the anti-dive feature?
Off the top of my head it could work that way if you like. Thing is, different THCs handle things in their own way - some use the plain vanilla functionality built into Mach - some add to that via plugins and some via brains for example. As you're implementing your own it's kind of up to you how you do it.

Hope this helps

Cheers

Ian

Thanks Ian,

After looking at it for a moment, I suppose I could do something like:

If the Anti-dive enabled LED is on, then activate output whatever...

Maybe in a brain or a macropump?

I'll have to look into that scheme when I have a bit more time.

Thanks again,
Chris
