I click home and the laser homes to front left corner. Loaded a 390 x 390 waste grid. Click frame and it starts. Most of the time it will fram but stop short of home limit switch. Sometimes as it frames I get a buzz noise from motors and it stops way short of limit switch. Move the laser by hand, not areas it is sticking. Tried to burn pattern, laset just went back and forth on same tract, 4 passes. I use lightburn on another computer, same model laser.
