 To use mesaflash to discover sserial devices, you would:

sudo mesaflash --device 5i25 --sserial

if you don't know the possible mesaflash commands,

mesaflash --help

From the hostmot2 manual page:


           sserial_port_N (N = 0 .. 3) [optional, default: 00000000 for all
           ports]
               Up to 32 Smart Serial devices can be connected to a Mesa
               Anything I/O board, depending on the firmware used and the
               number of physical connections on the board. These are arranged
               in 1-4 ports (N) of 1 to 8 channels. Some Smart Serial (SSLBP)
               cards offer more than one load-time configuration, for example
               all inputs, or all outputs, or offering additional analogue
               input on some digital pins. To set the modes for port 0 use for
               example sserial_port_0=0120xxxx. A "0" in the string sets the
               corresponding channel to mode 0, a "1" to mode 1, and so on up
               to mode 9. An "x" in any position disables that channel and
               makes the corresponding FPGA pins available as GPIO. The string
               can be up to 8 characters long, and if it defines more modes
               than there are channels on the port then the extras are
               ignored. Channel numbering is left to right so the example
               above would set sserial device 0.0 to mode 0, 0.1 to mode 1,
               0.2 to mode 2, 0.3 to mode 0 and disables channels 0.4 onwards.




 
 

Raspberry PI4 test version of the project is now online in the test branch (with docs how to connect), if you are interested try it, more info on the discord channel.

In the meantime, I’ve slowly started building the prototype.
I’ve decided to go with LinuxCNC in combination with the Mesa 7i96s and the THCAD-2.
All parts were initially 3D printed in ASA-CF.
In practice, it will have to be determined whether this material is strong and rigid enough.
If not, the parts will be replaced. For now, I want to test the concept first.
The axes are driven by 3Nm Nema 23 stepper motors and an HTD-5M timing belt with a 15-tooth pulley, without any gear reduction.
The frame will be made of stainless steel square tubing, 50x50x3 mm.

I’ve just started working on that.

Any tips or feedback are very welcome! I'm here to learn
