So I have this POS chinesium CNC laser gantry unit with an IPG YLS2000 and a Raytools head, and I'm running out of ideas. It is consistently slagging the cut in 10ga hot roll steel, but only in the upper left quadrant when cutting a circle. For the most part it cuts fairly clean, but every so often it just starts slagging with no apparent change in parameters or setup, and nothing I do will change it. It always generates slag in the upper left quadrant, cutting either direction, and sends a shower of sparks across the top of the part toward the 7-8 o'clock direction. In the other three quadrants it cuts clean with no sparks on top of the sheet. I recently dissassembled the entire laser head and went through it, and the laser cut considerably better for a while, but the issue is back with a vengence. Even when cutting well however there was always a hint of sparks and slag in that one direction. I have checked the perpendicularity of the head to the table, the levelness of the gantry itself, the laser concentricity to the nozzle (as close as I can make it with a microscope to check with), and the shape of the laser hole (cut half way through a piece of packing tape, fairly cylindrical). I am leaning towards either the gas jet is blowing to one side for some reason, the beam is not exiting perpendicular to the laser head, or the capacitance follow is varying based on direction (maybe a signal interference issue?) Is this an issue anyone has seen before?
