I keep having an issue specifically when cutting birch plywood. Occasionally on a cut path, the laser will leave a spot that is still connected almost like a tab. If I copy the object 50 times and make a large grid of cuts it will happen to one or two of them. Its not the file its the laser, but I dont know if the lasr is losing power or if the material has weirdly random spots that are difficult to cut. Usually its a super small short section I can cut with a box cutter but the picture below is the worst to date. It looks fine on the front, but for a random section it couldn’t get through the material. Any thoughts? I am running a G-Weike LC6090 with a Ruida controller.
PS: the cut looks wide and out of focus because there are two cuts there .020 apart so that the cut out puzzle piece fits in easier.
