Hello, I'm back again with some more issues. we got the configuration working and everything,last time. and i finally got the design program all worked out and the g-code worked out. So naturally its testing time. Today was going to be the firs cut but everything would go right until the torch had to fire. Which it wouldnt do, so i thought about it a bit and realized i put the torch fire on the wrong output when setting up plsamc. so i went back to reconfigure it, well i typed it wrong and now it wont let me reconfigure. im getting these error messages

When opening Linuxcnc:
(i was going to copy and paste it here but for some reason i cant copy or paste erro messages from linux so there are picture linked) imgur.com/a/gpia5al

When i try to edit the plasmac again:
Traceback (most recent call last):
  File "linuxcnc/configs/plasma_cutter/configurator.py", line 517, in on_create_clicked
    self.reconfigure()
  File "linuxcnc/configs/plasma_cutter/configurator.py", line 1801, in reconfigure

That mentions a permissions issue, did you do something as sudo.

Yeah, it gives me that message when I press reconfigure on the plasmac config panel. i tried opening up the plasmac config panel with sudo before it like this, but get this message when i press reconfigure:
user@debian:~$ sudo python linuxcnc/configs/plasma_cutter/configurator.py
linuxcnc/configs/plasma_cutter/configurator.py:2442: GtkWarning: Attempting to store changes into `/root/.local/share/recently-used.xbel', but failed: Failed to create file '/root/.local/share/recently-used.xbel.B4DJR0': No such file or directory

That is because it is looking for the home directory for the root user and it does not exist.

You do NOT need to be the root user to create or modify any LinuxCNC configuration. Doing so WILL cause issues.

Run this as the normal user:
sudo chown -R user:user ~/linuxcnc/configs/

Then run the Configurator as a normal user:
python ~/linuxcnc/configs/plasma_cutter/configurator.py

Ok it seems to have let me reconfigure the plasmac then. But I get the same error message when opening linuxcnc. The only thing that’s different is the debugging information which is the following:

Note: Using POXIS realtime
Iptable: No chain/target/match by that name.
1468
Stopping realtime threads
Unloading Hal components
Note: Using POSIX realtime

It won’t let me copy and paste. So I have to do picture. Sorry I open it up through a desktop shortcut

In the first picture:
Pin hm2_7i96.gpio.009.in does not exist

Try:
hm2_7i96.0.gpio.009.in

You can directly edit the_plasma_cutter_connection.hal file to fix it

I edited it to where the line reads this:

net plasmac:arc-ok-in hm2_7i96.0.gpio.009.in => db_arc-ok.in

I still get an error message. I’ll have to do pictures again. Could a problem be if I have more then one machine config?
