  1. You will need different aluminum profiles, stepper motors and rods depending on your 3D printer model.
  2. (1) z-Motorholders, left and right
  3. Insert a M6x12mm Hexagon Socket Head Cap Screw into the inside of the z-motor mount and screw a T-Nut to it loosely from the outside. Repeat this step for the second z-motor holder. Place a M6x12mm Hexagon Socket Head Cap Screw in one of the two holes of the corner bracket and screw a T-Nut loosely onto it.

    • Repeat this step for the second z-motor holder.

    • Place a M6x12mm Hexagon Socket Head Cap Screw in one of the two holes of the corner bracket and screw a T-Nut loosely onto it.

    • Repeat this step for the second corner bracket.

  4. Align the T-Nuts and the y-carriage (see Fig. 1). Make sure that there is one T-Nut in front of the hole and one behind it in each of the y-aluminum extrusions. Place your z-extrusion over the hole in the y-extrusion and fix it from below with a M8x40mm Hexagon Socket Head Cap Screw. After tightening, loosen the M8x40mm Hexagon Socket Head Cap Screw just enough so that the profile can still be moved easily in all directions.

    • Place your z-extrusion over the hole in the y-extrusion and fix it from below with a M8x40mm Hexagon Socket Head Cap Screw.

    • After tightening, loosen the M8x40mm Hexagon Socket Head Cap Screw just enough so that the profile can still be moved easily in all directions.

  5. Slide the z-motor holder (the opening must face inwards) into the front slot of the z-extrusion. Then, press the z-motor holder onto the y-extrusion so that it rests straight on it. Slide a corner bracket into the rear slot of the z-extrusion. Slide a corner bracket into the rear slot of the z-extrusion.
    • Slide the z-motor holder (the opening must face inwards) into the front slot of the z-extrusion. Then, press the z-motor holder onto the y-extrusion so that it rests straight on it.

    • Slide a corner bracket into the rear slot of the z-extrusion.

  6. Press the z-extrusion onto the surface of the y-extrusion so that the corner angle rests squarely on it. Now, tighten the previously attached M6x12mm Hexagon Socket Head Cap Screw to the z-motor mount and the corner bracket. Now, tighten the previously attached M6x12mm Hexagon Socket Head Cap Screw to the z-motor mount and the corner bracket.
    • Press the z-extrusion onto the surface of the y-extrusion so that the corner angle rests squarely on it.

    • Now, tighten the previously attached M6x12mm Hexagon Socket Head Cap Screw to the z-motor mount and the corner bracket.

  7. Position the 2x T-Nuts on the y-extrusion under the opening of the z-motor mount and under the hole in the corner bracket. Take 2x M6x12mm Hexagon Socket Head Cap Screws and screw them loosely into the 2x T-Nuts. Place the z-alignment tool on the rear part of the x-extrusion and push the z-extrusion against it until it touches the tool.
    • Position the 2x T-Nuts on the y-extrusion under the opening of the z-motor mount and under the hole in the corner bracket.

    • Take 2x M6x12mm Hexagon Socket Head Cap Screws and screw them loosely into the 2x T-Nuts.

    • Place the z-alignment tool on the rear part of the x-extrusion and push the z-extrusion against it until it touches the tool.

    • Now, fasten both the M6x12mm Hexagon Socket Head Cap Screwattaching the corner bracket, and the M8x40mm Hexagon Socket Head Cap Screw.

    • The M6x12mm Hexagon Socket Head Cap Screw on the z-motor mount remains loose for the time being.

    • Repeat steps 6 and 7 for the other side of the frame.

  8. First, you have to distinguish between right and left z-stepper motor. The right z-stepper motor comes with a long cable and the left one with a short cable. Cut 15cm and 60cm from your Techflex tube. The remaining 25cm are used in manual 10. The two ends of the Techflex tube are briefly heated with a lighter.

    • The two ends of the Techflex tube are briefly heated with a lighter.

    • Now, push the motor cable of the left z-stepper motor through the 15cm Techflex hose and the motor cable of the right z-stepper motor through the 60cm Techflex tube.

  9. First, remove the POM nuts from the two z-stepper motors and set them aside. They will later be needed for the construction of the x-axis. Place the z-stepper motor next to the z-motor holder. The cable should be aligned towards the rear of the frame. Carefully slide the z-stepper motor into the z-motor mount and make sure that the cables are not pinched.

    • Carefully slide the z-stepper motor into the z-motor mount and make sure that the cables are not pinched.

    • Press the z-stepper motor up from below until it snaps in.

    • Place 4x M3 Washers in the z-motor mount.

  10. Screw the z-stepper motor to the motor mount using 4x M3x10mm Hexagon Socket Head Cap Screws. Make sure that the z-stepper motor is completely straight. Now, push the Techflex tube surrounding the cables attached to the z-stepper motor as far into the z-motor mount as possible.

    • Make sure that the z-stepper motor is completely straight.

    • Now, push the Techflex tube surrounding the cables attached to the z-stepper motor as far into the z-motor mount as possible.

    • Tighten the M6x12mm Socket Head Cap Screw in the z-motor mount on the y-axis.

  11. Place a z-rod in the hole next to the z-stepper motor on the z-motor mount. Carefully tap the z-rod straight into place. Place a z-rod in the hole next to the z-stepper motor on the z-motor mount. Carefully tap the z-rod straight into place. Place a z-rod in the hole next to the z-stepper motor on the z-motor mount. Carefully tap the z-rod straight into place.
    • Place a z-rod in the hole next to the z-stepper motor on the z-motor mount. Carefully tap the z-rod straight into place.

  12. Turn the screw cover onto the z-stepper motor until it is almost at the bottom of the spindle. At the very bottom, put a drop of Screw Lock on the spindle and turn the z-screw cover above it. A gap of 1mm should remain between the bottom of the z-screw cover and the top of the motor. Regularly check whether the screw cover is properly seated. It must not rest directly on the motor which will otherwise be blocked.
