Gscreen force to mm and homed was created by terkaa
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.

Hi,
There is mm/inch button on top right corner of Gscreen. I believe it affects only to DRO readings. Inches are not needed here so it will only cause confusion if I leave it there....

Ok, so I changed mm/inch button from visible to unvisible with Glade and toggled metric from Gscreen preferences. That made the trick there. Modding hal file like this made homing unneeded:
net x-is-home halui.joint.0.home halui.joint.1.home halui.joint.2.home halui.joint.5.home halui.machine.is-on
Tero
net x-is-home halui.joint.0.home halui.joint.1.home halui.joint.2.home halui.joint.5.home halui.machine.is-on
