How can I change $30 and $31

This may be worth review.

Travel speed and cutting/engraving

When traversing between cuts or scans, LightBurn uses whatever the maximum travel rate of the controller is (the max rate numbers you highlighted above). When scanning, LightBurn uses the same speed across the entire scan because that produces the most consistent quality of output. You can set the Fast Whitespace Skip value Rick highlighted above to go faster through blank areas if you like. Just pointing out that these are different settings that affect different parts of a job.
