InstructionsVideo 1 Attach the top clamp and bottom clamp onto PEEK insulator and Teflon insulator using five 16mm M3 screws. Force the screws through the three leveling holes until they can move up and down more easily.Video 2 Lift the extruder with 8B leveling mechanism and thread it in reverse using 20mm M3 screws. Thread from the bottom of extruder clamps through the bottom of 8B leveling mechanism, then remove the 20mm screws. They will not be used on the part, only for threading.Video 3 Screw 30mm M3 screws into the three holes you just threaded into your 8B piece. This time, screw them in the correct way from the top part of 8B down. Line up leveling clamps with springs and 8B. Attach three locknuts to the ends of your 30mm M3 screws to keep the part together. The part is designed to slide up and down the three 30mm M3 bolts when force (leveling action) is applied. Screw in 12mm M3 clamp screws through 8B from the front.Video 4 Use the three 30mm M3 screws to level and pull upward, and two 12mm M3 screws to push down on the leveling mechanism. Unscrew the clamp screws before leveling up. Loosen leveling screws if you want to use the clamp screws to push down. You will need a Ultimaker Z-axis end-switch fine-adjuster for this setup.
