How do I unlock Luban

I am trying to resize a picture to laser engrave but I cannot manually change the sizes - width -height - as it shows a lock in between the two - can it be unlocked?

You can’t change the aspect. It’s a known bug that has been marked to be fixed.
You can type in a size or you can change the size by dragging on the handles in the workspace.

Thanks for your reply but I have tried that also and when I change the width the height automatically adjusts itself and I cannot change it or the width automatically changes.

Yes. That’s the bug. You can’t unlock.
You’ll have to do it in your graphics program.

Cura will let you unlock the scaling, and it’s very similar to Luban. Luban’s 3D Printing really is Cura with a bunch of settings hidden.

Cura doesn’t help for laser.

Lightburn does though.

:man_facepalming: I’ll just leave now.

Thank you for the suggestions everyone I will be sure to try them.
