I just tried the "This is a LED indicator" example from the pyVCP manual and it seems I broke something.
Created a file called tiny.xml wich contained the following:
Then I ran this command from terminal:
here is the output from terminal:
And now I get an error when I boot and I don't know where to go from here. Any help would be appreciated. File attached:
*update* - LinuxCNC will start on second attempt. Perhaps the tiny.xml file should be in a different folder? I put it in the ~Emc2/configs/HEALD folder.

Ok. so I added this to the .ini file:
And the AXIS GUI will load with the led indicator in the top right corner (I didn't hook up hal pins yet)
My questions are: What do the error messages mean? Do you have to run the "halrun -I loadusr pyvcp -c mypanel tiny.xml" command if you are making a panel to run within AXIS?

Just tested it out and it appears you do not need the aforementioned Terminal command for creating a panel within AXIS.

All is good and working as intended. I thought I made a mess of things when I got the error messages, but everything ended up working out fine.
