Peter, So I was messing with the $30 numbers and a test file I have for different laser power setting (10% - 100%) and the lower I go with the $30 number the more powerful the power output seems to be. If I set to 1000 the laser will not start burning until around 30% to 40%. If I set it back to 255 it will start burning around 10% - 20%. I have the JTech 2.8w if that makes a difference. Does this scenario sound correct? Your post earlier made it sound like this number shouldn't have an effect on power because its all calculated however I'm finding its making a difference. Am I doing something incorrectly?
