The setup is to design yet. But I suppose that all motors can not stay at
their end stops simultaneously. Rather in the middle position, but there's
no switch there.
It's probably better use magnetic alignments as Peter says.
42m/S might be fun to see..

Max velocity of the whole motors range is 6 m/s. Even at 6 m/s the output
rate of 1um encoder is very high, and other questions arise.
But this is something like linear motor too
