THC plasma configs, with HOW TO.

You might just have to adopt this config but its still experimental....

@Tommylight & @Grotius; I've been following this thread and have attempted to modify the existing files to my 7i96 build with little success. Because I'm running steppers on every axis and am not using any PARPORT's on the expansion header, I keep running into errors. Is there any way I can get one of you to modify the files to work properly on a pure ETH setup, or explain to me how to modify it myself?

I've been trying to marry the Toma THC into my machine file with no success for the last week and I'm just too green on the HAL front to make any great strides.

Because the 7i96 is a good low cost option for ETH boards, it would go a long way in giving community support not only to the 7i96 board, but to the LCNC Plasma community as well.

Added a new version that works with Linuxcnc 2.8pre.
Updated READ ME.
Easier to edit with much more info.

Please do check the first post on this thread.

Added a config for Mesa cards using stepgens on all axis. Config named "plasmat"
Tested on a 6i25 with 4 stepgens ( only 3 used by the config, easily modified for gantry setups requiring 4 stepgens), using inputs and outputs on a 7i77.
Should work with stepgens form 5i25, 6i25, 7i92, 7i76, 7i76E, 7i96 etc. Some pinouts already set in the IO.HAL file, just uncomment them and comment out what you do not need.

Added configs for Mesa servo systems on all axis.
Added config that works with Mesa THCAD, it has also provisions to generate ARCOK signal from pre-set min/max values on screen, so lees wiring needed.

Toma I am wondering if there is a function on these configs that would allow an ohmic sensor to stop motion if the torch unexpectedly runs into a piece of metal during rapid moves?

As it is, I have to keep an eye on my table while cutting, sometimes a piece of cut metal doesn't fall completely out and sticks up at an angle and if the Safe Z height is too low the torch will catch the scrap piece and lose steps or will move the sheet a bit.

My torch configuration is fixed in place i.e. no magnetic holders or breakaway function.

Thank you!
