Well I found the answer elsewhere, I went to Edit and at the bottom of that list select “Device Settings” once there I went to the bottom right where it says “S-value max” it said “250” for my setting and I changed it to “1000” and immediately all my issues with the laser were gone. Do not ask me to explain, because I do not know, what I do know is that it fixed my problem.
That is a relevant setting but it should not have spontaneously changed. Did you recreate the device, reinstall LightBurn, or are you possibly using a different device profile than the one created for the device initially?
