⬢Place parts on the frame as shown in the picture. The small circular opening should be closer to the frame outer edge.

All screws in this step are M3x10 (6 pcs).

⬢Use 2.5mm Allen key to tighten the parts to the frame. The screws must be perpendicular to the frame.

Note: If you have troubles tightening the screws, try to place them on the other side of the frame to clean the thread. Then place them again from the previous side. Proceed with caution, or you might break the screw.

⬢Remove the trapezoid nuts from the motors.

⬢Screw the Z-screw covers onto both leadscrews.

⬢Place the Z motors on the frame.

⬢Z motor left (labeled with Z axis left )

⬢Z motor right (labeled with Z axis right, longer wire)

Use M3x10 screws (8 pcs) and M3w washers (8 pcs).

⬢Use 2.5mm Allen key to tighten the motor to the printed part.

⬢Insert M3 nuts (4 pcs) in the printed parts as shown in the picture.

Nuts orientation does not matter.

⬢Use M3x12 screws (4 pcs) to tighten nuts in place.

⬢Use 2.5mm Allen key to tighten the screws.

⬢Insert Z-rods (the shortest ones) inside the Z-axis-bottom parts.

⬢Carefully slide the X-axis on rods and trapezoid screws. By rotating both screws simultaneously let the X-axis to slide until both trapezoid screws are exposed as in the picture.

⬢Place parts on the frame as in the picture.

⬢Ensure the smooth rod is aligned with the top surface of the Z-axis-top part. Check both sides of the Z-axis.

⬢Use 2.5mm Allen key to tighten the parts to the frame.

All screws in this step are M3x10 (4 pcs).

⬢Insert the zip ties in the holes at the bottom of the frame.

⬢Tie the cables to the frame as shown in the picture.

⬢Note that the left Z-motor cables are tied with the last zip tie.

⬢Grab the Y-axis assembly in your hand and slide it into the frame.

⬢You should be able to lift the constructed printer as a whole.

⬢Tighten the M10n nuts to the frame.

⬢Insert the flat part of the X-GT2 belt (longer one) into the X-carriage as in the picture.

A reference video is included at step 25 covering steps 16-24.

⬢Guide the belt around the pin as shown in the picture.

⬢Insert the belt all the way into the belt holder as shown in the picture.

⬢Guide the X-axis belt through the X-end-idler, around the 623h bearing with the housing and back.

⬢Guide the X-axis belt through the X-end-motor, around the GT2-16 pulley and back.

⬢Remove the two M3x18 screws.

⬢Rotate the motor counter-clockwise as shown in the picture.

This step is illustrative, you don't need to remove the frame.

⬢Guide the belt around the pin as shown in the picture.

⬢Push the belt all the way into the X-carriage.
