Updated to version 2.1.01 on my Mac running Sonoma 14.7.6. Lot’s of changes to get used to, but oddly the software is stuck in Imperial units “in” and can not be changed to Metric units “mm”. When clicking in the toolbar on “mm” it shows the toggle button as selected momentarily, but immediately g…

That is not something I’ve heard of anyone having before. That sounds a bit like a stuck keyboard button. We’ll have to see if anyone here is running that and try it.

Thank you for the quick reply! Not a stuck keyboard button since this is a non issue with version 2.0.05 that I still have (luckily I didn’t delete it). I just recorded a screen capture of the issue if it helps to see what I am experiencing. [lightburn_debug] On an unrelated note, my camera show…

For the units issue, can you go to Help > Generate Support Data and email that to support@lightburnsoftware.com with a link to this thread? I’m not sure if what’s happening is related to your config or not, but in case it is, that’ll help. For the camera, I’ll have to pass that to @JediJeremy - he …

MacOs 15.7.4, LB 2.1.01 I can’t reproduce this error on my system.

And sure, I will go ahead and email you guys the support data and a link to this thread. I appreciate you guys looking into it!

@SenecaStudio can you try this build? Index of /private/2021_patch-lightburn@units_fix/

Great work, Adam! And a really fast turnaround is much appreciated! :slight_smile: I installed the dev version but did NOT import preferences to have a clean slate for testing. And I chose a dummy device for testing the units glitch/bug. The good news is it works as expected and the problem is f…

Damn - I should’ve specified to let it import the settings for the production version. In this dev version, can you possibly go to File > Preferences > Open Prefs folder Then close LB (the dev). Then delete the contents of that folder. Re-open and let it import from the production version. Then t…
