Streamline your machine's appearance and functionality by relocating your stepper motor with this low-profile configuration. This substantial plate not only increases the clearance between the motor and the lead screw but also reduces the visibility of the stepper motor, providing a cleaner look for your machine.

    Reducion/Stand Off Plate Set

    Posted by M. Miller on Aug 18th 2019

    i purchased this as the tail-end phase of replacing the existing z-axis on my MaslowCNC Router, which I used the CBeam Linear Actuator kit. However, at 200mm height the z-axis motor would have sat on top of that, introducing some top-heaviness not to mention some plain odd looks. So I wanted to invert my z-motor. This kit fit the bill - exactly what I needed. However, the 8mm bore clamp collar did not want to tighten securely. The set screw always bottomed out. A heavy set of vise-grips brought the collar together enough to get a tight fit. Just food for thought on that last bit. All in all, I am well pleased!
