Gscreen force to mm and homed

Hi,

I would like to know if it is possible to force mm/inch button to mm mode at loading Gscreen also I will be using absolute encoders do I would like to be "homed" at start. Any pins for these that can be set to 1 at HAL ?

You might be able to just use NO_FORCE_HOMING in the INI file:
linuxcnc.org/docs/2.7/html/config/ini-config.html#_traj_section (bottom of the [TRAJ] section.

You can configure immediate homing by setting home search and home latch velocities to zero for each axis.
That still needs you to press the "Home" button, but there is a HAL pin for that too, which could be linked to the machine-on signal or similar.

Ok,

What is this Hal pin that can be used for this? (I believe that was the actual question here )

halui.joint.N.home

Part of halui: linuxcnc.org/docs/2.7/html/man/man1/halui.1.html

halui runs in userspace, so be aware that it isn't ideal for time-critical functions. But auto-homing isn't time-critical.

Ok,

This is good info. Now I still have figure out how to make mm default and disable inch button. I believe it is time to learn some glade UI...

What do you have in [TRAJ]LINEAR_UNITS ?
linuxcnc.org/docs/2.7/html/config/ini-config.html#_traj_section

I would have expected the GUI to look at that.
