Back Plate

The back plate requires a minimum build volume.

  • Minimum Bed: 165mm x 135mm

Servo Assembly

The servo mounts are secured to the back plate with screws and nuts. The micro servo is fitted into the servo mount and secured with screws. A ball bearing is fitted into the servo mount to counter weight the servo arm. The servo arm is secured to a servo horn and press fitted onto the shaft of the servo motor.
