    • Highlighted holes are going to be drilled in next steps.

  6. Using the assembled P-drill, drill the highlighted holes from previous step (increase the diameter of the original holes used for zip ties to secure bearings). Rotate with the P-drill assembly clockwise as shown in the picture.
    • Using the assembled P-drill, drill the highlighted holes from previous step (increase the diameter of the original holes used for zip ties to secure bearings).

    • Rotate with the P-drill assembly clockwise as shown in the picture.

    • Apply force downward through the Y-carriage.

    • It's similar to opening a wine bottle, but don't apply that much force or the drill bit will get stuck. If it gets stuck, just rotate the opposite direction and repeat with less force.

    • If the drill bit is slipping in the printed part, just tighten the M3x12 screws a little more.

    • Don't drill the Y-carriage directly on the table, you can damage the surface. Use cardboard or empty filament spool as an underlay

    • Ensure the P-drill drills few millimeters through the Y-carriage.

    • Proceed to the next chapter - 2. XYZ-axis reassembly
