On the breakout board for a 3 axis machine you will have 6 outputs X, Y, and Z, step and direction.
You will need to find out where these 6 wires need to go on the internal Roland board so that the board can power the steppers.
Failing that you will have to throw the Roland board away and fit three new stepper drivers that you have a wiring diagram for. Then wire the logic side to the breakout board and the output side to the existing steppers.
In the long run this may be easier as you then have known and replaceable components instead of a very old Roland board that could crap out at any moment.
Chances are the Roland board is either full step or half step at best. New drivers will give you micro-stepping to get a smoother drive.Last edited by John S; 24-10-2016 at 06:47 PM.
