for 1 do you mean add it here??
 

this I have no idea how sorry still a rooky
2. launch the pinirq script at startup (there are a couple of ways to do this
easiest may be with crontab)
 

GRUB_CMDLINE_LINUX_DEFAULT="quiet isolcpus=1 acpi_irq_nobalance idle=poll"
 

Ok after I make the change to the grub as above I then use crontab to create an operation to run the pinirq script a boot time. With a ctrl x to write it.
@reboot chmod +x pinirq,txt
sudo ./pinirq.txt eth0    should there be a @ at the beginning of this line too???

the script is already on the hard drive from the last time I used it

You don't need to chmod +x more than once so
chmod +x pinirq,txt in unnecessary (and will fail
because crontab has no idea where pinirq.txt is located)

Not sure about crontab and sudo
(will it ask you for a password during startup?)
So the systemd method of launching scripts at startup
may be better

Note that sudo ./pinirq.txt eth0 will fail because again crontab
does not know where pinirq.txt is located (you need a full path
or copy pinirq.txt to a standard executable directory like /user/bin/
Also pinirq.txt should probably be renamed just pinirq or pinirq.sh
(it only has the .txt suffix because that's required to be able to post it to the forum)

@reboot is what tells crontab to do the operation only at boot time

How about @reboot (full path location) pinirq (renamed just ) pinirq
next line ./pinirq eth0

@reboot  sudo pinirq eth0 

assuming pinirq is in /usr/bin/

done deal I can move it and remove the .txt from it
Thanks

Eine kleine Frage….
wenn es nötig werden sollte eine THC Carte zu verwenden würde ich die gerne im Plasmagerät einbauen…
Muss die Spannung von der 7i96s kommen oder kann ich für die Versorgung der THC Carte ein Externes nehmen ?
Wenn der Encoder Eingang potenzial frei ist ja aber ist der das ?

Von 7i96S.
Kein externes strom, das macht probleme mit potential und interference.
Das sind nur 4 drahte fur die THCAD von Mesa 7i96S, dan 2 fur torch on und 2 mehr wen die ARCOK von plasma nutzt.
Ein gute CAT5 oder CAT6 LAN cable mit schirm (shielded) ist OK.

Ok tommylight und danke….
Torch on und Ark ok sowie 0-10 V für den Strom habe ich im Standart-Anschluss Zwei hätte ich frei gehabt der Anschluss ist aber nicht geschirmte !
Nun gut wenn das Probleme macht das bekommt das Gerät ein weiteren Plug mit Cat-Kabel.

I am working on retrofitting an old cnc plasma.
It has a standalone thc, a hypertherm phc.
Since the thc controls the z axis, the only outputs I think I need for it are cycle start and corner hold/thc off.
Im using a mesa 7i97t so I haven’t be able use mesact to configure it for qtplasmac.
Ive been trying to get it to work in roundabout ways, but the more I learn about qtplasmac, the more I feel like qtplasmac is a poor choice. I love the plasmac look, but it seems way too complicated to make it work with no z, no probe/ohmic, and not being integrated with gcode that wouldn’t be used with my setup.

So I’m trying to figure out which gui would give me the best start for a simple plasma with minimal inputs and outputs. Should I continue trying to use qtplasmac or would axis, gmoccapy, or? be a better choice.

I used to use sheet cam for a mach3 plasma that I had set for super simple gcode. I’d like to use sheetcam again, and keep the gcode simple. 

Does it also do Initial Height Sensing on its own?

Yes. But it doesn’t have a specific input for it. It has a cycle start input that will cause it to initial height sense and start the arc. It also has a switch for doing the initial height sense.

Same thing, been in daily use for over 8 years now. It also had its own THC so no wiring or programming was required for it.
Torch cycle is wired in hal and physically to M3, and the arc ok from plasma is wired to motion inhibit in hal so the machine does not move until the torch is actually on and cutting.
It uses Axis GUI as is, not PlasmaC nor QtPlasmaC.

That looks similar to what I’m trying to do.
Id like the gui to not have a whole bunch of unnecessary clutter and just add a few buttons and indicators.
Looking in the linuxcnc manual, under axis customization hints, I see “difficult to customize.”
That statement makes me hesitant, since I’m just a beginner with linuxcnc.

So would you still recommend axis even if I’m a complete beginner? 
Is gmoccapy easier for a beginner to customize? 
Or should someone like me just focus getting a working machine and minimize customizing?
I’d hate to go through this retrofit and have a screen that looks like it should be on a mill, but I can get over that if it’s unrealistic for a newbie set up a custom plasma display.
