Seeing excessive whipping on the Y1 ballscrew when operating the break-in routine (400 IPM). The Y2 side is fine. Tension seems consistent between the two sides and is within spec (3/8" movement by hand). In fact, I’ve got noticeable deflection in both of the far side mounting brackets - don’t want to get past some yield point…maybe I’m paranoid. Reset the ball screw end bearing mounts using the bar holding tool and reset the motor assembly alignment to the ball screw. Made no difference. Pretty frustrated at this point. Will try to measure sag at a set weight to better calibrate.
This is a square up against the frame and against the bracket holding the ball screw mount. About 1/8" deflection.
