Does this gantry movement look normal?
I have a PS48 laser from full spectrum laser. I have had nothing but problems with it. I have replaced the controller with a ruida, the tube,the tube supports, the mirror mounts, the mirrors, the lens mount, and the focal lens. I am still not able to keep it in focus. I have gotten it to cut well for about an hour maybe two of running, but then it goes out of alignment and just won't cut.
I know that there isn't much left that I haven't directly replaced and calibrated. I know the tube is putting out power and the mirrors are not over absorbing the beam. One piece that may still be defective are the bearings. I've read about this, but I haven't been able to find anything about what it should look like, or any examples of what a defective one would act like.
Does this movement look normal?
Does anyone have any other ideas?
