Grumpy_Mike:
Is this possible,
You would have to arrange a multi way switch or set of relays to switch the motors in and out of circuit
Not something many people want to do.
And of course physically breaking the connection to a powered up stepper winding is likely to
both burn out the stepper driver and weld your relay contacts shut - unless you power down the
driver before switching.
The first rule of stepper motors is don't disconnect a powered up motor...
