I have the 7.2 gear head steppers on my bot, and now I am looking to further increase my resolution. Does anybody have any ideas of the next step? I am seeing the resolution 'chatter' on aluminum parts cut on the angle (using both x and y axis to cut a vector). I would like to see those lines go away and for my parts to resemble things made on say a Haas or other metal specific CNC.
Has anyone installed helical rack on their machine? I'm not sure if its the straight toothed racks and gears that are causing this chatter, or the stepper motor resolution.
