I've got a China router with YooCNC step/dir driver boards
and I've bought a Usb controller card from Planet CNC which I'm going to wire to the YooCNC driver boards.

I don't have any good documentation on the YooCNC so I'm a bit unsure on how to wire it to the USB controller.
Anyone who have done this?
Or anyone who can help me with this?

Here's how I've wired it:




Thanks
