Hi guys,

If I mount the rails on the carriage side (vertical moving part) of the z-axis and mount the trucks on the tower part. I can get better clearance for higher work pieces. I will have about 6-8" travel on the z-axis.

The concern is then the ball screw supports must also be on the carriage side, and the ball nut is mounted to the tower. This means I have significantly more weight on the carriage, the carriage is extended farther out which also creates a larger twisting moment about the linear rails.

Anyone have some insights about whether its worth it or not?

Thanks,
Colin
