Yes, my lathe and mill systems are separate. As I use DB9 connectors on the
motor cables, I do occasionally plug in one or two cables to my driver box
for testing other stepper motor hardware. Fairly easy and quick with the
DB9 connectors, probably not so easy with your connectors.
All the cautions about switching motor wiring are valid. And one might even
say don't be tempted to buy heavy duty 4DDT switches to accomplish the task.
First thing you know (at least for me) you'll switch with the motor power
on, and OOPS!
How expensive is the motor driver box? I visited Flashcut many years ago,
and really wanted one of their systems. Almost got to "check out" a system
before shipping to Malaysia.
Just as a note, if you can do "startup" of your CNC controller program
(FlashCut) in two separate directory installs, then you can have two copies
of the INI or config file (works for other systems as well), and simply run
one or the other executable and get a different setup.
