You can see in the photo and the video how there is a very dark vertical line on the left and right of each test square. That is where the machine is coming to a stop in its horizontal (y axis) travel, turning off the laser, moving a couple of millimeters, stopping and then turning the laser back on and then continuing to move. The result is there is overburn on the left and right edges of each test square.
In the video it is more easy to see the gantry starting and stopping.
I would have expected the behavior of the laser to move in one continuous motion over the entire horizontal length of the test grid while turning the laser on and off.
Even if the laser gantry needs to stop after every small horizontal scan of each box. It was my understanding that the overscan feature would turn off the laser before the gantry stopped moving so that this kind of overburn wouldn’t happen.
I would like to eliminate the dark vertical lines on the left and right of each of the test squares.
