How tight are you guys compressing the cork pads on the y end supports to the frame? I have mine pretty tight but I worry it will negate the damping the cork pads are supposed to provide. On the other hand tighter is stiffer for the motion axis and I don't see a reason why high frequency vibration will exist on the frame since the motors are already decoupled from the frame - so not sure if damping from the cork is really necessary there.
You shouldn't compress them too much, until the commissioning phase. And even there, tight is tight, never ever overdue things, it will break something somewhere. Vibrations will occur just from the movement of the head while printing. Those are a bit buffered this way. Only my idea on the matter Regards T.
Yea, I am specifically referring to compression during commissioning phase. It's hard to gauge how tight to make them (of course w/o overdoing it). I have them decently tight now and the cork well compressed.
