    • Looking from the back of the printer we will now focus on:

    • The right XY idler

    • The left XY idler

  3. Attach the right  XY Idler base to the frame. Fasten the nuts firmly Repeat for the left side Repeat for the left side
    • Attach the right XY Idler base to the frame. Fasten the nuts firmly

    • Repeat for the left side

  4. Slide the 3030 M6 T-nuts' into their place in the extrusion Fasten the xy_idler_right to the frame with the two Countersink Screws M6x14 and one Cap Head Screw M6x12 that goes in from the side
    • Slide the 3030 M6 T-nuts' into their place in the extrusion

    • Fasten the xy_idler_right to the frame with the two Countersink Screws M6x14 and one Cap Head Screw M6x12 that goes in from the side

    • Prepare a Cap Head Screw M5x40 but do not thread it in yet.

  5. The order for the bearing stack from the bottom is: shim, idler, shim, 2x 6mm spacer, shim Thread the bearing stack onto the Cap Head Screw M5x40 Attach the M5 nut from the bottom, do not over tighten - it should be snug but should not prevent the idler from spinning

  6. Repeat the same steps for the left XY Idler assembly.
    • Repeat the same steps for the left XY Idler assembly.

    • The only difference (aside from it being mirrored) is that the bearing stack is upside down - from the bottom it's: shim, 2x 6mm spacers, shim, idler, shim
