I am using Windows 11 and I have installed MACH3 in my laptop using closed loop motors. Additionally, I am using a USB MAch3 Motion Control Card. According to internet page this card con be used only up to Windows 10. What could it be the issues using this card with Windows 11?

Which card are you using?

IT’S A WIXHC MK4 MACH3 MOTION CARD

Have you tried it with Win11?  All motion controllers need a specific Windows plugin, it may just be that the one for this controller hasn't been tested and integrated with Win11 yet.
