100% on both Min Power and Max Power? Or just Max Power? Your profile says, “Chinese Laser” for the machine type, which is like saying, “my car has wheels”. 
If you have a Ruida controller, at or below 10mm/sec, the controller uses the Min Power value only, so if you are doing really slow cutting, and aren’t setting that, that’s your problem. If you cut at 10.1mm/sec or higher, the controller ramps from Min Power up to Max Power as you get to the requested speed.
This lower value is also commonly called ‘corner power’ as it’s the power setting used when the controller slows for sharp corners.
