I have a 3018 DIY machine with a 5.5w laser. I use fusion 360 to create my sketch and gcode. I then use LaserGRBL to send the gcode to the 3018. The issue is I get these random lines show up that are not in Fusion 360. I am using GRBL Laser for my post processing. Any thoughts on this? I am new to DIY CNC.
