Depends on the mill or? In the case of my G0704, the accelerometer

Yes, certainly, it’s the table that moves. I was thinking of some
kind of CNC router. But I think the idea is the same, yu’d see very
quickly if there was any kind of error to be corrected out. Even
on the 3D printer, you would need an accelerometer on BOTH the print
head and the table.
If its a bed slinger, yes, but corexy or a ender 5 only needs one in the
head.
My guess is that massive tables don’t shake much.
This is no doubt true, but the same thing could measure the windup in
the typical spiral coupling between motor and screw and reduce the
motion lag at a speed change too.
