    • NOTE: The following procedure must be performed before the epoxy begins to set. Be sure to read through and have all parts/tools ready.

    • NOTE: The X-Plate render in this guide has been updated, but does not affect the assembly process highlighted in this guide.

  2. Orient X-Plate as shown. Mix a small portion of epoxy and carefully flow into each of the (5) locations that house the linear shafts for the kinematic coupling. These are marked in Blue. Caution: Introduce only enough epoxy to secure the linear shafts from the bottom sides. Too much adhesive can affect tool-change performance. The epoxy only needs to retain the shafts when no tool is mounted.

    • Fit (5) 3x8mm linear rods into place. Once installed, do not allow them to rotate. This could bring adhesive to top of the rods. Press firmly and wipe away any excess epoxy from the face of the X-Plate.

    • Place an 8mm steel ball in the center of each coupling and install clamps to apply a moderate amount of pressure to the coupling. Pressure must be applied perpendicular to the coupling.

    • NOTE: There are many styles of clamps that will work for this, but any clamp with sharp teeth should be avoided.

    • Allow to fully cure (ideally overnight) before removing clamps. Set Aside. The remainder of the X-Plate will be assembled later.
