Hey,

I would like to put buttons on my VCP that will run a python script. I want to call hole_circle.py with a button. Thank you for the help as I'm new to linuxcnc and making custom panels.

You can easily embed code in a GladeVCP panel (in which case you use ordinary Glade buttons, rather than a hal_button).

This would be helpful if you were using GladeVCP.

You would need a very minimal Python handler loaded at the same time as the GladeVCP.

However, you are trying to do it with PyVCP, and that is somewhat more kludgy.

The only way that I know to do it with PyVCP is to have the PyVCP pin connect to a halui.mdi-command-NN pin, and then have that MDI_COMMAND call the script as a custom M-code.
