Auto Home when Linux CNC starts was created by CrashCNC
Is there a way to automatically home when Axis starts?
What can be added to the .ini? Or does it need to be a custom HAL function? linuxcnc.org/docs/2.4/html/gui_halui.html

I would try loading a python program that sets homing using the python linuxcnc module.
Something like:
Something like:
#!/usr/bin/env python
# -*- coding: utf-8 -*-
import linuxcnc
c = linuxcnc.command()
c.home(-1)
c.wait_complete()

Good idea.
I'm familiar with the python script but have no idea how to make that code automatically launch when starting the axis GUI.
Any insight?

load it with HAL in the post_gui file:
loadusr python PATH_OF_SCRIPT
would probably work, but you would need to add to the script to clear estop and turn the machine on.
I must say it scares me a bit about what you are doing... I hope you have a good reason and safety plan![:) :)](/media/kunena/emoticons/smile.png)

Have you seen NO_FORCE_HOMING in INI settings?
Or execute the python script through halui.machine_is_on
What you are doing is dangerous, so do not blame anyboddy if something goes wrong!
