When I engrave anything the laser goes to very low power even though power is set to 80%. If I use laser GRBL the laser works perfectly, so it must be a problem with my settings on lightburn. It worked fine on my other laptop but not on the new laptop. any ideas please

Did you use the bulk transfer feature to copy all the old Lightburn settings to the new PC?

Do this to solve that:

Likely S-Value Max and $30 are not the same. First point in the quick setup…
