Using U Axis for Rotary

I have the 6442 also… I also have all the hardware, but still use the Y axes…

I keep meaning to give it a try and see what happens…

Is this documented somewhere? It seems when people ask about what controller to buy … it would be a good to know…

I normally ‘hot swap’ my Y with the rotary… so far so good …

This is from this thread, similar
