Welcome to the forum!
For many DSP controllers, there are some things to consider. You will have to unplug the Y motor to plug the rotary motor in. In this instance, you would also need to change the current between the stock value (ex: 3.5 amps) and 1 amp for the rotary each time you are switching between normal Y and the rotary.
It is best to install a separate external stepper driver and then you just have to swap a connector plug each time you want to switch between the normal Y motor and the rotary. The external stepper driver should be set to approximately 1 amp and the rotary stepper motor should be cool to the touch.
We recommend reviewing the Rotary Setup doc for general information on setting up and dialing in your settings.
Additional information regarding features and add-ons, as well as DSP external stepper drivers and Ruida controllers is covered in our Rotary Attachment announcement.
If you still have questions about compatibility, please provide pictures of your Ruida controller, stepper motor drivers, wiring, and electronics.
