Calum,
SS probing:
The probing issues with the SS are that the tip comp values returned by Mach are incorrect. I don't know if the root cause is in Mach or in the SS plug-in. I know that Brian has looked at the issue, and I think it may be fixed but hasn't shown up in a developement release yet.
Black Button image:
This is a mach bug awaiting a repair - see mach errata section in the MSM release notes.
NH/NRH LEDs:
See MSM release notes. These changed in Beta 5. They now change label text (NH or NRH) but do not change color.
The conundrum was that neither RH or NRH are more "right/wrong" than the other - so there was no intuitive pair of colors to use for the LEDs.
CV Angle:
Thanks for spotting this.
I've changed the button from CV angle to CV distance (The function was always CV Dist).
It turns out CV angle does not seem to be in the script APIs so I can't show it on the setting page. CV feedrate and CV dist are what 1024 has and the same controls are on the MSM page.
This change will be in the next MSM release.
