I'm trying to combine etches and cuts to create detailed pieces that are then cut out. The problem I'm having is the laser is going out of alignment after the etch, so the cut doesn't line up. For laser ply, I etch at about 200, 40% power, and have a small circle as a reference point so my detail and cut line up, so I've attached a picture of these to show how far it's being thrown out. Is this a sticky wheel on the gantry, or the speed of the etch vibrating the machine? Anyone else experienced this, or know of any way to fix it?
