Mm/sec then inches/sec

Why does the speed change from mm to Inches when going from one project to another or going to a new project. I’m using LightBurn on A XTOOL D1 Ptk 20 watt.

Some folks work in inches and some folks work in mm.

The units of the speeds may change depending on who wrote the file and when it was saved last. Most of the Gcode lasers use mm so the imperial or SAE inch-size and inch-speed translation is in LightBurn. Because of this, the speed itself should be the same.

the mm vs. inch toggle button should adjust it to your liking.

If you save it after you change it, that setting should stick.

If it doesn’t stick, hopefully we can figure out why and make this work more to your liking.
