I am away from the code for at least one more day. I'll give you some clues for now and give a more precise answer when I am back.
You *must* set up spi. The other pins are set up as needed. Use free-run mode and you don't need them.

Spi is setup using stm32duino standard spi functions.
Somewhere in lib/soes c or h file (also check subdirectories to lib/soes) there is a call to
spi_begin(). Find that . Check there for pins, speed, and Chip Select. And set them to match your dev board.
Use slow speed to start with. Increase as it starts to work. I have on max now (80 MHz?), was on some kHz when troubleshooting.

Actually #if 0 all ethercat code and use the normal arduino setup(), loop() for encoder testing.
If you use serial port output it must be explicitly opened or something, check code.
You should be able to come a long way and then I'm back.
 

Just as a general thought, no GUI configurator can fully support the 7I76EU
(or any other hardware) , though I think MesaCT does support the output options.

In all but the simplest cases, some hand editing of hal/ini files is likely to be needed
and considerable hal customization will be needed for functions like tool changers,
spindle orientation, jogging options etc etc.

The SKR1.4 is not actively supported and the ethernet demo was an early concept testing. Please check this link for ethernet supported boards.

Cakeslob also has his F4 repo

To something like this:
"

This avoids the issue of people taking your code and relicensing it under GPL v3, which is incompatible with v2 (one way compatibility).

You could add a clause stating that your name and "jethornton" shall remain in all documantation and license files.

Any one using this card?

I bought similar but not the same. Most important is that, there is custom bitfile preloaded at factory. If your's card works, do not try load any other bitfile.
I have some files received from seller (in attachment), the mesa-rtcp config is works for me, but not all resources are configured.

Hello, 
I have now got all axes running.
I would now like to set up homing. 
When I start homing, the axes start moving.
However, the home switches are ignored and the axes continue to move.
I have linked the home switches in the HAL as follows:

net X-home-sw        <= lcec.1.6.din-4        => joint.0.home-sw-in

Is this correct, or does the home switch have to be set to HomeSwitch(DI3) from the A6 servo drive?

Hello,


With the help of @Hakan, I will try to make a SinCos encoder input ethercat compatible board.
I'm a beginner so please don't give credit to my post, this is a learning project.
chip used: STM32F407VE and LAN9252

Here is the git project: 
github.com/paulsvc/Firmware

Done:
Step 1: Quadrature Encoder input 

Ongoing:
Step 2: Ethernet layer

@Hakan, I struggle to setup the ethernet part. I use the following pins:
SPI2_MISO: PC2
SPI2_MOSI: PC3
SPI_IRQ: PA8
SPI2_SCK: PB10
SPI_NSS: PB8
SYNC0:PC6
SYNC1: PB15

I went through the EASERCAT7000 project but I'm not sure when do you setup these previous pins

Thank you in advance for your help

Is there a way to manually apply the Monokrom filter plasma_gcode_preprocessor to a G-code file outside of Monokrom, just to see what the output looks like?

Does Monokrom have an option to save the current G-code file? (I can see that it might well not have, as you can't typically change the file in the GUI, so there is no point). 
You might be able to view the file-as-run in the GUI though, and see something odd around (I stress "around" as the reported line number can be off by several lines) 

Unary operators are things like SIN[] COS[] etc so I would be looking for unexpected square brackets.

While waiting I've got to find a better solution to using these fine wires from the sensors and pendant into the terminal blocks.

Maybe bootlace ferrules? Effective at stopping stray strands bridging between channels. 

(And some of the crimpers are fun - there is a little video of a 6-segment one here, though the 4-segment ones work better in cage clamps, I feel.

Your configs are in your ~/linuxcnc folder so keep it. If you used the linuxcnc ISO
sudo apt upgrade might do it.

I just published a video on how to upgrade to 2.9.7 on Trixie because it has 2.9.4 available in the Debian repos.
The apt pinning method I describe could be used on Bookworm as well. In fact uninstalling linuxcnc and removing the linuxcnc.list file in the APT folders would let you follow my Trixie method on Bookworm just keep the sources files pointing to bookworm

Thanks a lot for this information. Currently I will stay with the sourcing Outputs. I just started with LinuxCNC and don't plan to modify the Hal-File by hand at the moment (Pncconf is currently my approach).
If I'm more experienced with LinuxCNC I will do this modification or maybe a new LinuxCNC version is available which fully supports the 7i76EU.

I saw this thread and went down a similar road trying to get a user tab set up for surface compensation. The linked repo was indeed incomplete, but I was able to use it as a starting point and get this working with some trial, error, and LLM assistance.

Hopefully someone will find this useful: github.com/Blair-Johnson/surfacemap_usertab

I see you  suggested these servo drives:  www.aliexpress.us/item/3256808075045002.html  I like the idea, but the only ethercat products I have experience using with LinuxCNC so far, is Beckhoff products. If these drives are compatible with LinuxCNC, I say go for it. I bought a similar ethercat servo last year. It is still patiently waiting for me to try it out. For the weight of your machine, if you use the 1000W size, I am sure you will not be sorry you went with that. It will help increase the acceleration/deceleration speeds when jumping from one cut to the next. Can make a huge difference when you get to cutting lots of small parts. Tomorrow I might have a chance to look at a Messer plasma table about this size when I'm out on another project, I will see if I can check what size motors it has.

You will probably want to power the Plasma table control cabinet using 240 volts AC (220).

I looked at your long list again. My opinion is a.i. bots frequently over engineer a lot of insignificant points.
