Home designed and built 5C CNC lathe with ATC and C_Axis

if you just
loadrt near

You get the the count option and the default count is 1 if not specified
if you specify a count (N) , you get N instances of near with indexs
from 0 to N-1

If you use the names option, you get as many near instances
as you have names.

I presume 'my' near.0.in1 = the example's spindle-at-speed.in1 ?
and you specify names.

Yes, if you use the names options, near.N.whatever is replaced with your_name.whatever

Don't give up.

Apart from anything else you are likely to have exactly the same problem with spindle deceleration with Mach, and I wouldn't want to guarantee that there will be a solution there.
