Think there’s a typo on the Lightburn Layers and Layers Settings page of the online class: the line below.
The POWER settings should be set to the same number in almost all instances. Valid values are 10-70 and should never go above or below those numbers.
That reads to me like the numbers should never go above 10 or below 70.
Saying ‘Valid values are only in the range 10-70’ is clearer to me.
