Huh ?
One single cable around the perimeter, single pulley block in each corner, no crossover = shorter cable, less stretch potential.

Must be some other reason.

Spalm,

The reason they are crossed is so that if the gantry is pushed on one side the other side is pulled via the cable.

I've gotta make a few phone calls today and see if I can't come up with another motor this seems to be the easiest way of dealing with the whole situation.

I don't see any way to do it with "One single cable around the perimeter, single pulley block in each corner, no crossover".

My bad, Guess I was up too late last night and my mind was stuck on that drafting table in which the Tsquare slid on the cable. Yes you need the cross over.

Thank you for not laughing at me,
