Hi:
You dont need Out of Band or anything, in Mach4 you need to set a spindle range ot the first spindle range setting.
Then in Darwin diagnostics, set frequency controlled spindle. Set a minimum and max frequency the vfd or controller
for the spindle can handle. THis doesnt mean the same as the mach4 range. For example set mach4's range from
0 - 2000rpm.. then set darwins range from 500 to 20Khz.. you basically match frequnecy with the RPM it will create.
Turn on debug messages as well just in case. Also tell M4 that the spindle output is active.
This will giev you a step/dir spindle with no direction. TO change direction just creata another signal called SpindleCCW
and tell M4 it exists. That should be enough to make a step/dir spindle work. M4 has its own Spindle control fir such things
but like much of M4 , its still a mystery how it works until there are docs..
