@mfs12 I'm also interested in an autocalibration feature. Would the right way to go about it be to have the printer oscillate the print head in one dimension at a time with varying accelerations and distances and use the accelerometer data to find how much distance the frame moved as it shook? The largest displacement will indicate what the natural frequency is of the printer frame in the respective axis.

That information could be used to dynamically adjust jerk and acceleration values of the printer before the next move takes place.
