Homing of A axis from a button was created by kenwoodhf
I have built a gantry router machine and I am using a tangential knife on the A axis. After turning the power off and on a few times the A axis starts loosing it's reference. Is there command I can put in the g code file that will rehome the A axis before the program starts? Or can I make a custom button that will rehome? Just need some guidance if it can be done.
Thanks

In the INI file under [JOINT_n] for your A-axis, there is a setting for forced homing:
Try setting this to "1" and see if that helps. It should force you to re-home the A-xis if you power off the machine or e-stop (either physically or through software in LCNC)
VOLATILE_HOME = 0

Thanks for the information
I works as you described and I am happy with it.
To home the A axis I have to go to Machine/Homing/Home joint 4. I was hoping to make it a bit easier.
I down loaded Glade and after a few youtube videos I tried to make a A Homing button but I can not see or find a link to my button. Maybe it is there in some other form.
Thanks for your help

I don't know glade, maybe you can repost (or moderators can move this) specifically asking how to create a button in Glade with that function.

I just downloaded Glade into my LinuxCNC Debian 10 machine. I watched a bunch of you tube videos and now trying to produce a button that is linked to Home A axis. I can not find a link for this button. It may be there but I can't see it or maybe there is some other way. I know I can home the axis by going to the drop down menu Machine/Homing/Home joint 4 (A axis) but I would like to make it a bit easier.
Hope someone can help.

But if you still would like to do that with a Glade button, you have to use the function in your button callback function. See linuxcnc.org/docs/2.9/html/config/python...mand_code_attributes for reference and also for an example.

Thanks for the advice. On my axis main page pushing the Home All does home all my axiss (XYYZA) . I installed VOLATILE_HOME = ) in the A axis in the ini file to force me to rehome the A axis after I cycle power. It is nice to know that making a Glade button is possible but this is something I really need some help on.Any guidance would be welcome.
Thanks again
