I was doing some 3D surface cuts with my CNC and noticed that the axis
movement was jerky. This problem made the machine frame rock back and
forth to a surprising degree. I was given the recommendation to go to
micro-steps on the 1200 oz*in motors. I did change the jumpers on the
geckos and that didn`t seem to make a difference. I then increased the
acceleration of the motors in Mach3 by over 50% of their previous
value. Should I now be concerned that I might be more prone to miss-
steps. This change made the steppers perform very smoothly and that
disconcerting gantry movement disappeared.
PS...once in a while I also hear a high pitch vibration coming from the
steppers.The noise is intermittent. I wonder what is the cause of the vibration?
