I am very new to this. I have a 50 wat ebay blue laser with a ruida controler. Can someone explane, or send me a link to explane how to use max power , and min power settings. Should i keep them at the same settings, or not ?
Very basic explanation is that if you are cutting you can keep them the same and if you are doing gray scale engraving you can have them output different levels for the colors.
Again that is very basic. There can also be some use cases for corners, start and end points. This can also be addressed by looking at lead in and lead out options in LB.
for some more research
