2nd IM was almost assembled and shipped to Kamioka together with the 1st IM.
In the 2nd IM, one of the screw was stucked when assembling the side wall (spring side).
I think shorter screw can be inserted, but the long screw cannot be screwed fully now.
Anyway, it works without that screw.
And the heat shrink tube is running out.
So I did not connected the top picomotor cable.
