LB version 2.1.01 - fails to go into metric mode when running on my laptop

LightBurn Software Questions
1

PC system: Lenovo 81x7 laptop running Win 11.

Lightburn fails to change into metric units. It defaults to Inches, but neither the menu icon radio button nor the file menu settings will change it into metric units. The radio button will highlight and darken when I press it, but will remain in Imperial units. Same with the menu settings. I can change the units there to metric, but when the menu goes away after accepting the change, the software remains in Imperial.
This is new behavior. I’ve been able to change from Imperial to Metric in previous versions of the software on the same laptop.

Repro is 100% on my laptop. The behavior seems to be only on my laptop. The software works fine on my PC desktop and allows me to change between the units at will.

I’ve re-installed LB v2.1.01 twice and restarted my laptop both times without any change in behavior.

In the Settings window, below the units pulldown, is a switch. You can now link design and control units. Make sure the pulldown is correct for your machine control. Turn off the switch so you can design in inches or metric, but it will not change your Layer speed settings.

I was able to solve the problem on my laptop by going to Device Settings; Control Units and turning the Link Control and Design Units ON, then set the units to in / mm/sec

I had to do the exact opposite. I had to turn off the Link Control and Design Units. My settings were already set the same as Granpa_Laser when I when to try the solution.

Perhaps it’s the toggling that’s the fix.
