On the final path to finishing this project.... So I have a 1000mm x 1000mm cnc. Which the Y - axis has 2 motors at the rear turning each a 8mm lead screw in a c-beam. With a over head x-axis with single stepper with 1000mm 8mm lead screw. When the y-axis moves +/- it makes a loud buzzing or vibration. I tried to figure out the location but seems to have no area I can pin point it. It appears to be a vibration sound.. I can press on any of the y-axis or cross members I see feel the vibration. I can not seem to figure it out, but thinking it just normal noise made from the steppers moving the lead screws. I have watched and measured many times the movement of both sides of the y-axis of the x-axis to make sure there no binding etc. Also x-axis makes a similar noise but not close to the volume. Any ideas?
