I have a home built cnc router that has x y z axis and just added a axis. what i do now is unplug Y motor and plug in A motor, is thier a toggle switch that will do this . all motors are 4 wire so 4 wires in from control box 8 wires out to A and Y. suggestions please.

There are 4 pole double throw switches available If you must do it that way. Be sure to turn the power off before moving the switch so yo u don't blow the driver. I would find a way to add another stepper driver instead.

You could actually get away with a DPDT switch and just the positive leads and leave the negatives connected. Again, power off switching only.

thank you for the help i will try the switch. money very tight at the moment but will use the proper way when i can.

As @rcheli write ALWAYS TURN OFF power before flipping a switch or your tight budget will be blown with the drivers
