Hello
i'd like to implement a retrofit for my old machine, his technology is old and limited, the servodrives are controlled by bipolar voltage +/-10V
i tryed to get the MESA board for years but i've problems to get it due to availibility
anyway...
reading many interesting topics and i'd like start a big challenge , i've got SPI 16bis +/-10V and a Colorlight 5A-75B board as Litex CNC by ethernet, i can see in the documentation; that project is focused to control stepper motors, for that reason i have some questions, i hope you can suggest me how set this proyect down.
im worry how migrate from stepper to that analog signal
thanks so much

I would really, really avoid using those boards on a big machine especially with analog drives/motors.
And Mesa has available boards for analog systems, just not the usual ones like 7i77 and 7i97, so you can get a Mesa 7i92 OR 7i96S and a 7i83 and 7i85, that should be all, except if you need more IO, then add a 7i84.

thanks for the information, i just ordered a 7i97T
as soon to arrive i'll starting work on it .
i have all infomation about this machine, parameters, plc logic....
now... what are your recommendations to a good starting?
