I went back to 2.9.0~pre that is in Debian 12 and reverse works but
forward does not cap the speeds. I would suggest changing the wording in
the docs in updating linuxcnc from 2.8x to 2.9.y to 2.8 to 2.9.1 and
later to be more specific that it only works with 2.9.1 or later. This
may be where I was confused as I "think" I only tried forward. Also in
the spindle section of the ini docs note that those 4 limits only work
in 2.9.1 or later version.

Now I'm really confused as to why it didn't cap the values because it
works this morning for all 4 ini items on Axis 2.9.1.
Sorry for the static.

Is this only in master and the docs are wrong or is this just broken?
Probably just broken.
The INI settings do get read:
https://github.com/LinuxCNC/linuxcnc/blob/2.9/src/emc/ini/inispindle.cc#L65
And fed into the spindle settings:
https://github.com/LinuxCNC/linuxcnc/blob/2.9/src/emc/ini/inispindle.cc#L100
And set here:
https://github.com/LinuxCNC/linuxcnc/blob/2.9/src/emc/motion/command.c#L1555
And the code here (setting the HAL pin values) appears to limit the
velocity:
https://github.com/LinuxCNC/linuxcnc/blob/2.9/src/emc/motion/control.c#L1908
(Though it looks like I might have got my > and < the wrong way round
for negative spindle speeds.
Can someone else check that I am not double-thinking this?)
