Hi guys,
A few years ago I converted a New Hermes engraver to CNC using Xylotex drives and Mach-3 controller (my post describing details is on this forum). Well, I recently noticed a "growling" vibration coming from the X/Y table when I move it in the +Y direction at high speed. All other axes and directions are smooth and quiet. My Y axis carries the X axis motor and lead screw, therefore it carries the biggest load (if that makes any difference). When I jog the Y in the positive direction, the table starts out smooth and quiet but then starts to growl and vibrate after a second or two of movement, becoming louder and stronger over a short distance. It seems to me like something is mechanically resonating, but I'm not certain. I tried retuning the Y axis using different velocity and acceleration numbers, but that did not help unless the table moves very slowly (which is unacceptable). So, my questions is, Is there some way to filter the resonance/vibration in the Mach-3 software? All axes use standard stepper motors.
Thanks!
