Hi Stitos,
When raster scanning the axis has to accelerate from zero to full speed at the start of each line and then decelerate from full speed to zero at the end of each line (as defined under the motor tuning parameters). If the power level was not reduced proportional to the axis speed then the laser would cut deeper as it slows towards the end of travel.
Getting the power level and / or feed rate just right perhaps requires a bit of practice.
