    • 2x Ball Bearing 6007ZZ

    • Insert the 8 nuts in the pockets of the axis sides.

    • Attach the ball bearing housings on the back of each axis side and fasten it with M5-20 screws as shown.

  4. Finally, place the ball bearings inside the pockets created.

    • Finally, place the ball bearings inside the pockets created.

  5. In this step you will need: 1x side assembly (the one without the homing sensor holder) 4x M5 slot 6 nuts, 4x M5-10 bolts

    • In this step you will need:

    • 1x side assembly (the one without the homing sensor holder)

    • 4x M5 slot 6 nuts, 4x M5-10 bolts

    • Screw the M5-10 bolts through the side assembly as shown on the second picture and attach the M5 slot 6 nuts

    • Finally slide the whole piece inside the frame as shown (bottom side touching the frame) and secure it by screwing the 4 M5-10 bolts.

  6. In this step you will need: 3D Printed: Worm gear Thread lock glue

    • In this step you will need:

    • 3D Printed: Worm gear

    • Thread lock glue

    • 2x M5 nut, 2x M5 washer, 90mm M5 threaded rod

    • Apply glue as shown.

    • Follow the diagram for the dimensions.

  7. In this step you will need: The previous worm gear assembly. 3D Printed: Worm mount

    • In this step you will need:

    • The previous worm gear assembly.

    • 3D Printed: Worm mount

    • 2 ball bearings 625ZZ

    • 4x M5 nut slot 6, 4x M5-10 screws, 2x M5-10 washer.

    • Insert the ball bearings inside the pockets of the mounts. Then screw the bolts into the nuts slot6 as shown in the pic.

    • Finally slide the worm mounts in the slot 6 rails as shown. First the one without the gear assembly first, then the second with the gear assembly as shown.

    • Don't forget the washer between the ball bearings and the worm gear assembly.

  8. In this step you will need: The second axis side assembly (the one with the homing sensor holder)

    • In this step you will need:

    • The second axis side assembly (the one with the homing sensor holder)

    • 2x M5 slot6 nuts, 2x M5-10 bolts

    • 2x M4 slot6 nuts, 2x M4-20 bolts

    • The stepper motor mount.

    • Attach the bolts, slot 6 nuts and the stepper motor mount.

    • Finally attach the whole assembly to the frame as shown in the picture.

  9. You will need: The homing sensor electronic circuit

    • You will need:

    • The homing sensor electronic circuit

    • 1x M3 nut, 1x M3-12 bolt, 1x M3 washer (not shown)

    • Mount the homing sensor on the axis mount as shown.

  10. In this step you will need: 3D printed: Axis spacer collar 3x M3 nut, 3x M3-10 set screws

    • In this step you will need:

    • 3D printed: Axis spacer collar

    • 3x M3 nut, 3x M3-10 set screws

    • Insert the nuts in the pockets of 3d printed part, then screw the set screws as shown.

    • You may need to sand the final surface of your 3D printed part (check how it fits inside the side ball bearings.

  11. You will need: The homing ring part 1x M3 nut, 1x M3-25 bolt.

    • You will need:

    • The homing ring part

    • 1x M3 nut, 1x M3-25 bolt.

    • One small piece of aluminum tape (or something that blocks the IR light)

  12. Insert the M3 nut to axis gear part. Pass the access through: Axis collar spacer

    • Insert the M3 nut to axis gear part.

    • Pass the access through:

    • Axis collar spacer

    • Homing ring

    • Axis gear

    • Warning: Make sure the hole is facing the top.
