Shows 4 configuration options for the ini file that don't limit the spindle rpm in any way, are these for master only?

4.1. Spindle limits in the INIIt is now possible to add settings to the [SPINDLE] section of the INI file
MAX_FORWARD_VELOCITY = 20000 The maximum spindle speed (in rpm)
MIN_FORWARD_VELOCITY = 3000 The minimum spindle speed (in rpm)
MAX_REVERSE_VELOCITY = 20000 This setting will default to MAX_FORWARD_VELOCITY if omitted.
MIN_REVERSE_VELOCITY = 3000` This setting is equivalent to MIN_FORWARD_VELOCITY but for reverse spindle rotation. It will default to the MIN_FORWARD_VELOCITY if omitted.JT

Not sure what makes you say they 'don't do anything'.
Adding this to the axis sim in a current build of 2.9:
seems to have the described effect:

I tried 2.9.pre (the one that you get from Debian) and 2.9.1 from a deb I downloaded and adding them to an Axis ini file and they do not limit anything. I put MAX_FORWARD_VELOCITY = 100 and can do a m3s50000 and it sets the spindle speed to 50000

My guess is this was added sometime after 2.9.pre but the docs are quite confusing stating 2.9.y which means nothing to me.

Ahh... that's where the Forum poster
(forum.linuxcnc.org/24-hal-components/566...6eu-hal-and-ini-file)
got 2.9 pre
The HM2_eth driver from that version also has bugs with 7I76EU configs
(it gets the name wrong)

If I interpret this correctly then it was added in 2.9pre:
github.com/LinuxCNC/linuxcnc/commit/3d00...37be66c946acc972636e

2.9 pre is years old and buggy. You can't depend on it. You really should upgrade to 2.9.4 by following the steps in the Getting Linuxcnc docs or adopt Debian Trixie pre-release as it should be out as the official Debian release next month.

I have no clue why this didn't work yesterday as it is working for me today... maybe a typo in the ini file who knows.
In 2.9.0~pre that ships with Debian 12 only the reverse caps work so that's why it didn't work for me as I only tried the forward caps.
