U Axis on a RDC6442G

Hello,

has anyone any information about controlling the U Axis on a RDC6442G.

Is this Axis output usable for eg. as rotary axis output or for what is it usable and how.

I hate rewireing the y stepper driver every time using the rotary jig.

A dream would be to have the y axis driven to the right position where the rotary jig is prepared to be mounted and then the u axis is ised to drove the rotary jig.

Any hint.

best regards,
Walter
