  1. Thread the Cap Head Screws M6x12 through the idler plates. Four screws per plate Attach the 3030 M6 T-nut to the screws. Don't tighten yet Attach the 3030 M6 T-nut to the screws. Don't tighten yet

    • 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
    • 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

    • If you are having trouble getting the bearing stack into place, thread the bearing stack onto a thread or a thin wire, then pull the ends of the wire through the holes in the mount, from the inside out. The bearing stack will slide into place.

  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

  7. This is how the XY Idler assemblies should look like looking from the back
