And unless you disable SPI you can not use the SPI pins for GPIO in linuxcnc

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.

Here is my fault information;

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.

Todas las fuentes de alimentación dan el voltaje correcto los motores se quedan frenados como si funcionaran pero no se mueven la verdad es que no se si se pudo aver quemado la placa.
Tengo cables blindados puestos a tierra aun que no si es una medida para que no se queme.
Que mas puedo comprobar?

All these elements are drawn to represent your machine limits and offsets:
The blue circle in the lower left corner is the home position.
The red rectangle shows the axis limits in respect to the home position (as set in the ini file).
The XZ coordinate system shows the current work origin (ie in your example you have an active work offset in x )

I apologize if I wasn't clear.
In the image you'll see a blue and red arrow I'd like to move them up on preview grid closer to the middle, as you can see the program path takes it right to the limit of the preview grid.

You don't really need the expanded tool editor for this:

 

Have a look at the sim config:

MESA 7i76E burning out issue

Category: Driver Boards

I finally found the real cause.

Today i got the amplifier fault on another joint (joint 0) and I found that it the problem happened whenever I turned on the spindle.

After several attempts to measure the ground connections the machine stopped in a position where I found the machine frame was not grounded.

The reason: The spindle connector got loose. The machine frame was grounded through the spindle cable, and that cable had become loose.

All I had to do was tighten the screw of the connector. Ground connection works reliably again and the machine runs well. Phew.

accidentally flashed my ethercat servo with something wrong, and restored everything with this tool and the original esi xml

so yes, it really works

I use it to configure my LAN9252 board

EDIT:
uhhh, found this site: markosankovic.github.io/2016/06/28/esi-to-sii-binary.html
i think i need to test this '
ethercat sii_write ...
'
I must have overlooked it somehow :)

Ok, I have seen those.
When you write an eeprom this way and then list the pdos with "ethercat pdos", do you see the ones you expect to see?
