Hi,
I bought an old plasma table with no control software key. Can I use Lenux cnc to control this driver? Thanks for your time.

It looks like it is probably a CANbus controlled sevo. So I'm go out on a limb and say probably not easily, if at all. If it is possible it would be bleeding edge and you'd need to know what your doing to set it up.
If you're lucky maybe someone will chime in with better news for you.
it is possible that the input pins labeled "input polarity" and "stp in" are or can be used as ordinary step/dir inputs for position control. If that is the case then yes they could be used. (You'd need to look up manuals for them to know.)

Have a look there: logosolinc.com/wp-content/uploads/2020/0...gent-Servo-Drive.pdf
This is the manual for the LS-132. I just can't find anything for LS-131 but they really look about the same
Then see here: logosolinc.com/software/#downloads
And HERE: logosolinc.com/cnc-software/
Not linuxcnc but may be a much easier path for you

It looks like it should be possible to control it with a Mesa UART
You would need to write a driver to create HAL pins (to communicate with LinuxCNC) and then to assemble the data packets.
This might not be all that difficult, here is a sample driver file (for an imaginary serial-controlled device)
github.com/LinuxCNC/linuxcnc/blob/master...ivers/mesa_uart.comp
It needs to create the pins, then have a setup function, a read function (to interpret the feedback) and a write function (to assemble data from HAL into serial packets)

Hi Andy
If you want to use a uart on a mesa card, would that require special firmware on the fbga card?
for example, if i have a 5i25 or a 7i92, and a 7i77+7i74 connected to it, do you need a special bit file to enable a uart on the 7i74 or would the standard bit file for this combination do?

Here is everything found on LinuxCNC web and forum regarding uart, pktuart included.

Look for a bitfile with "UA" somewhere in the filename.

Yes, though there might well be a suitable firmware available already.If you want to use a uart on a mesa card, would that require special firmware on the fbga card?
