[request for enhancement][documentation][configuration issue] Configure Spindle in HAL and config.txt files

[abe-mariani]

Hello,

in the full config.txt file the spindle pin seems to be not completely specified: there is only a comment and a "SP[i]" = 0.
Moreover, the NVEM/NVUM manual says the VSO pin is not a PWM output but a 0-10V output so a PWM configuration for the pin would not be appropriate in any case.

In the HAL file (full or basic) there is no configuration for the spindle control at all and there is no documentation to try and add the required functions on my own.

The LinuxCNC documentation says something like this is needed to drive a 0-10V output, but is it applicable to remora?

 loadrt scale count=1
 addf scale.0 servo-thread
 setp scale.0.gain 0.002
 net spindle-speed-scale spindle.0.speed-out => scale.0.in
 net spindle-speed-DAC scale.0.out => <your DAC pin name>

Would it be possible to add the relevant configuration fragment or adapt what is already there in these 2 files?

Best Regards,
Alberto M.
