Should I make a board with step and direction from both motors and a switch between them for changing? .
Sorry, for the newbie questions, but I try to figure this one out by myself.

Well, if the DM542 drivers are already built into two different machines, my suggestion might be more work.

What you need to do it the way you described would be a 4p2t (4 poles, 2 throw) switch or relay.
This can switch the 4 wires of the stepper between 2 sources, but the switch has to be rated for the full current of the steppers.
