Touch Off default value for offset

Hi,
I have recently installed a laser pointer with an 'X' pattern on my Z axis.  This pointer is offset from the router bit on the X axis by about 3" and from the Y axis by about 2".  When I touch off on an axis, I have to manually enter these values to 4 decimal places (something like -2.9693).  This works fine but I'd rather not enter these values each time I touch off on the X and Y axis.

Has anyone modified the axis.py script to allow for a default value to be specified in the .ini file so the offsets don't have to be typed in when touching off to the workpiece?

Thanks in advance.
 

What machine?
You can add a VCP button to do all that with just a click:
  linuxcnc.org/docs/html/gui/gladevcp.html

The machine is a homebuilt 3 axis gantry type.

Linuxcnc is 2.9 pre (and some long number) on Mint 19.3.

I'd really prefer not to have to give up screen real estate for a button.

Silly me, I didn't realize GladeVPC could run as a tab in axis. Looks like some piddling is in order. I need to get something working for a touchplate also so maybe I can integrate that.

. doubled up.

This is how I moved to the XY laser position using a gmocappy macro. Should work for you.

Jog to where you want to set 0,0 by the laser and press a button. Easy

I think that will work for what I need rodw. Thanks.
I was not having any luck with glade.

Just to follow up, with slight modification this works great for me from the MDI.
Thanks again.
