Have you looked at the sample config sim/axis/remap/rack-toolchange

You can run that as a simulator to see if it works like you want, and then look at the way it is done to adapt to your own needs.

It works by re-mapping M6 to call a G-code subroutine.

The 7I73 does not currently support any higher resolution  A-D modes,
(I think the issue was exceeded the total serial data available) but
one simple thing to try is to low-pass filter the 8 bit data from the 7I73
in hal before using it to control the spindle speed.

If the flicker is greater than 1 LSB it may also be that you are picking
up some noise in the potentiometer wiper line. You could reduce this
by adding a small (say 1 uF) capacitor from the potentiometer wiper
terminal to 7I73 GND.

I see, the "-m" flag makes it write the pdos.
But what about the sdos? I don't see them coming over.

I believe I figured it out. I was looking at it the wrong way. I needed to set the max limit in the ini file and then set the offset to move the home position further into the grid. I'm not sure if this is the correct way of doing, it but it got me the desired result.
This image shows my new position in the preview grid.

I'm sorry, I still don't get it.
Are you saying that 'G0 x0z0' moves the tool to the machine home position despite having set a work offset (ie the blue circle instead of the coordinate system) ?

Using 
mesaflash 3.4.9
 with a Mesa 7i76EU (IP 
192.168.1.121
). Ping works, but:mesaflash --device 7i76eu --addr 192.168.1.121 --readhmid
Unsupported ethernet device 7I76EU at 192.168.1.121
No 7I96S board found
Also tried with IP 
10.10.10.10
 after moving jumper W14 up
mesaflash --device 7i76eu --addr 10.10.10.10 --readhmid
Unsupported ethernet device 7I76EU at 10.10.10.10
No 7I96S board found
Is the 7i76EU supported? How to fix "Unsupported device"?

The images are setup and no adding users to groups or messing around is needed.
Read the following thread and you'll find a link to GPIO info and a working example.

The fact that it quit working after firing the torch suggest a grounding or EMI issue.

If communication work but you don't get motion, it may be they the step/dir 
output drivers have been damaged. One way to check this is to disconnect the
motor drive step/dir signals and measure the 7I96S step/dir output voltages

The step and direction output voltages should be in one state when the 7I96S card is 
first powered up, and in the opposite state when LinuxCNC is started. 

That is the output voltage should be very close to 5V in one state and very close to
0V in the other state.

If the voltage does not change or you get any voltage that not close to 0V or 5V, this
indicates damaged to the 7I96S step/dir outputs.

Hello to all.
I'm using Linuxcnc 2.9.4 on rpi5 debian bookworm that is installed from linuxcnc rpi5 image.
I have a problem on running my setup.
I tried many things like adding gpio to my user, creating a file 90-gpio-access that is mentioned on hal_gpio manual (linuxcnc.org/docs/devel/html/drivers/hal_gpio.html)

but I failed.

Thanks for the reply.
For now i will work on the 3D model for the whole machine.

That's the problem. It realigns the whole grid to wherever the home is set to. I can't find a way to move the grid itself. If I could keep the grid aligned with the physical home and off set the set home by 3-4 inches on the grid I would be happy. I can't seem to find a way to do that.
