    • Insert LM8UU linear bearing into the printed parts (X-end-motor and X-end-idler) as shown in pictures

  5. Insert the rods with bearings into the printed parts Distance between the printed parts should be around 303mm
    • Insert the rods with bearings into the printed parts

    • Distance between the printed parts should be around 303mm

    • Ensure the correct orientation of the parts and rods (rod with 2 bearings must be on the side with nut trap)

    • Insert the rods very carefully. Do not tilt the rods too much.

  6. Insert zipties into the X-carriage as shown in the picture Ensure the correct orientation of zipties (head of ziptie should face outside of the carriage)
    • Insert zipties into the X-carriage as shown in the picture

    • Ensure the correct orientation of zipties (head of ziptie should face outside of the carriage)

  7. Place X-carriage on the X-axis base as shown in the picture
    • Place X-carriage on the X-axis base as shown in the picture

    • Ensure the correct orientation of x-carriage

  8. Use pliers to tighten the zipties Make sure that bearings are in the position as shown in the picture (bearing should be as deep in carriage as possible)
    • Use pliers to tighten the zipties

    • Make sure that bearings are in the position as shown in the picture (bearing should be as deep in carriage as possible)

  9. Use pliers to cut off excess ziptie
    • Use pliers to cut off excess ziptie

  10. M3x18 screw
    • M3x18 screw

    • 623h bearing with housing

    • M3nN nylock nut

  11. Insert the 623h bearing into the X-end idler
    • Insert the 623h bearing into the X-end idler

    • Secure it in position using M3x18 screw

    • Tighten it with M3 nylock nut

  12. M3x18 screw X motor (longest motor) Tighten the motor to the X-end-motor part
    • M3x18 screw

    • X motor (longest motor)

    • Tighten the motor to the X-end-motor part

    • Ensure the correct position of cables (Cables should face down)

  13. Place GT2-16 pulley on X motor shaft
    • Place GT2-16 pulley on X motor shaft

    • Adjust the position as seen in picture (effective part of pulley should be in axis with X-end-motor cutout and one of the screws on pulley should face directly on pad on shaft)

    • Tighten up the pulley using 1.5mm hex spanner

  14. Insert the ziptie in the X endstop (the one of two with the longest cables) Guide the cables through X-end-motor part Tighten the endstop to the bottom rod (the one with the single bearing)
    • Insert the ziptie in the X endstop (the one of two with the longest cables)

    • Guide the cables through X-end-motor part

    • Tighten the endstop to the bottom rod (the one with the single bearing)

  15. Move the X-carriage on the end of the axis until it hits the endstop
    • Move the X-carriage on the end of the axis until it hits the endstop

    • Move the endstop to achieve around 10mm gap between the top side of the carriage and X-end-motor

    • Cut and discard excess ziptie

  16. Use ziptie to secure X-endstop cable to the X-motor cable as close to the motor as possible
    • Use ziptie to secure X-endstop cable to the X-motor cable as close to the motor as possible

    • Do not overtie the ziptie otherwise you can damage the cables

  17. Insert M5n nuts into the X-end-motor and X-end-idler Be careful when handling the X-axis after this step, the nuts can fall out
    • Insert M5n nuts into the X-end-motor and X-end-idler

    • Be careful when handling the X-axis after this step, the nuts can fall out

  18. Use the smallest and shortest spiral wrap to wrap the cables
    • Use the smallest and shortest spiral wrap to wrap the cables

  19. Congratulations! you've just assembled X-axis
