    I have some inexpensive NEMA 23 stepper motors. Other than a small rubber grommet where the stepper wire exits the stator/housing, I don't see much in the way of strain relief.

    I'm mainly concerned about the motors on moving parts of my CNC router.

    Is anything else done to provide strain relief to the wires until you can clamp them or get them into a conduit?

    So got a picture or current setup. I use ziptie's. You can heatshrink the motor wires together and then ziptie them in a non aggressive arc in to the motor housing. Maybe some form of plastic standoff. Then a drag chain run back to edge of the frame of cnc machine. Currently my Z axis motor wire is wrapped around the motor cause I just rebuilt the mechanics of the axis. But i think ziptie would be ok if you are constantly changing stuff.

    EDIT-Also Found this in resource section. If you have a 3D Printer!

    Yes. That's sort of what I'm doing started out with 3Dprinted parts as templates drilled holes and cut plates out on my table saw by hand. I mounted and built machine now hopefully gonna start cutting plates on machine to be more accurate.
