You actually should be able to check this out with
Halscope. Look at the velocity or step rate
for the Z axis, and trigger on spindle.0.index-enable or
whatever it is called on your LinuxCNC version. If what I
said was right, velocity should go higher than the required
Z feedrate for
a moment right after the spindle encoder gets the index
pulse, and then settle down to the required feedrate for
that thread pitch.
Love that rigid tapping! I just did 160 holes, with a spot
drilling step, then a drill through step, and finally
tapping some 6-32 and 2-56 holes. It is kind of scary
watching a 6-32 tap plunge in at
1000 RPM and 32 IPM feedrate. Taps the hole in barely a second!
