Material Cut/Scan Test Files - Power Scale

My power settings don’t appear to change anything. Am I missing a setting? OMTech 20W Fiber Laser using LightBurn 1.2.04 on a Mac running Monterey. Everything seems to fire and burn correctly after initial setup. Focus is good. It’s just that I get the same results no matter where I adjust the Power setting. Not even sure what power it’s ‘actually’ running at… Speed and Freq adjustments seem to work well… Just not Power.
