Yes, I've been using the machine since 2022 with no issue using the stock firmware, i'm only trying to use mesaflash now to use a fifth stepgen. is there something with my linux install that could have gone wrong?

Imaginative idea.

See the config
sim/axis/vismach/puma
for an example config including a graphical representation of the simulated robot.

Note that getting the Denavit-Hartenberg parameters exactly right is not a trivial task if they are not provided. (and there are two different conventions for them)

There are a few examples out there. Look on YouTube.
For example:

The new computer won't go past the boot screen. I fiddled around with the boot order etc but still no go.

You have to disable "secure boot: and UEFI in BIOS for it to work, UEFI is usually disabled by choosing Legacy mode in BIOS for boot devices/order.

Fairly mysterious...

Does LinuxCNC run properly?

 

Yes, 7i74 will do perfectly for 6i25 and add 8 more SSerial ports.
And yes, i have used many 7i74 (i have one on my Mazak lathe) as they make for cleaner installs as wiring to 7i70 and/or 7i71 is just a simple network cable.
@Andy,
see if you can source HP Z400 or Z420 or Z600 workstations, all have PCI slots, 420 has 1, 600 has 3 i think, and all have plenty of PCI-E. They are usually very cheap, but struck gold yesterday with 5 of Z600 :
forum.linuxcnc.org/18-computer/57073-hp-...or-use-with-linuxcnc

Yesterday i got 5 of Z600 workstations, as life would have after a friend gave one for free to me as i service and maintain his laptops and PC from time to time, i asked for the price as he had another 7 home collecting dust, and after quite a bit of back and forth (and bickering) we agreed on another 4 for 100 Euro total, making it 25 Euro a piece!
Wasted yesterday evening and night, and today all day testing and installing those, organizing memory modules (several types of several sizes on all of them) ended up 4 having 16GB of ECC RAM and one having 24GB of ECC RAM and some left over 2GB and 1GB modules, all have 128GB SSD and some have and assortment of spinning HDD's from 80GB to 500GB, all have old NVIDIA Quadro graphic cards that now seem pathetic compared to a GTX1060/6GB or RX580/8GB that i promptly switched to on two of them, all have 2 of Xeon 4 core CPU's at 2.4GHz, and proprietary 650W power supply with a single 6 pin VGA power connector, and all weigh in at over 20KG !!!
So far tested with Linux Mint 22.1 and LinuxCNC 2.10 on 6.13 RT kernel, all have very good latency from short test i did. Will do more tests and also add a parallel port to one to test with as they do have PCI slots.
Have to go to the shop and finish 2 more installs, so for now i leave you with this:
Do NOT buy raspberry PI, buy everything else.

The wayback machine might help.

w5 and W6 are set as such :

 

Can you ping the card?

How are jumpers W5 and W6 on the 7I96 set

What does:

ip a

report?
 


 

"no ethernet board found",

I must admit I am not super linux savy, could i be doing something wrong related to either the boards' jumper or some other config related issue?

The 7i74 is a good start, bit doesn't do much by itself.
The 7i73 is a handy little board for control panels and pendants.

You could also look at the Mesa 50-pin cards. I am a fan of the 6i24
They use different daughter boards to the 25-pin cards (eg 7i44 v 7i74 for smart-serial) but they use the same smart-serial accessory boards.

Just be aware that there are two separate daughter-board ecosystems.

An ethernet-based FPGA card might make for easier PC swaps in the future. My mill recently got a 6i24 side-grade when I couldn't find a PC with a full-size PCI slot to suit the existing 5i23. (they still exist, but I had other constraints like 12V power and M2 slot)

Strange, does:

mesaflash --device ethernet --addr 10.10.10.10 --write 7i96_5abob_d.bit --reload

work?


 

yes I ran your exact command

Did you add the "--addr 10.10.10.10"
