Interested in your controller.
I have a G11.
Can I use this with my original motors?
Thanks

Hi can't remember specifically, but if they a bipolar aka 4 wire only, yes they can.
It is very easy to add fast nema17 motors. plenty of info on that in forum.
This link gives you some idea from onstep site.

Edit:: The G11/G8 are among the easiest mount to work with for Onstep system
