Just transferred my mach3 folder from my old computer to new one.

New computer is and intel Nuc I5 with win 11 pro.

All the other screens open but when I click on motor tuning nothing happens

And machine runs fine.

I’m stumped and rather not install Mach 3 again

Unfortunately, I think a re-install is the only way forward.
This is the stock answer:-

'If you click on Mach3 Menu -> Config -> Motor Tuning and it just won't open, but everything else works, you will need to reinstall Mach3 again.

Something in Mach3 or the registry in Windows for Mach3 got messed up.  You should not need to do anything other than rerun the installer for Mach3 and then it should just work the next time you run Mach3.   That being said, it would be a prudent idea to make a copy of your entire "C:\Mach3\" folder first, just in case something goes wrong'.

Tweakie.

Yea I just reloaded everything and motor tuning is back

Thanks
