Z Axis Linear Rail Alignment

This document is actively being refined and edited for mistaeks.

At this point, all of our linear rails should be attached to an extrusion. The Z rails are aligned along the Z1 and Z2 extrusions with a bracket at the bottom. We need that bracket positioned when we assemble the frame, so we'll go ahead and lock down the rail, too.

Parts

ID Qty Description
Z1 1 PN729 with Linear Rail
Z2 1 PN729 with Linear Rail
PN019 2 Lower Rail Bracket
PN532 2 Screw, M5-0.8 x 12mm BHCS
PN577 2 Washer, M5, Split Lock

Assembly

A. Place Bracket

place the bracket

  1. Insert a lock washer and screw into one of the brackets.
  2. Set the bracket assembly on the lower end of the extrusion (following the FTL labeling rule)
  3. Line the base of the bracket up roughly with the edge of the extrusion
  4. Lightly secure the screw

B. Align

aligning with a 2040 extrusion

  1. Place a square or another piece of extrusion at the bottom of the bracket.
  2. Firmly press on the assembly to ensure alignment.
  3. Tighten the bracket in place.

C. Position Linear Rail

pushing the rail in place

  1. Push the linear rail into the new bracket.
  2. The bracket is a fairly tight fit; you may have to work it into place.

D. Tighten the Rail

locking the rail in place

  1. Check that both of the alignment brackets are flat to the rail with a good grip to center the rail.
  2. Tighten the first and last screws on the extrusion, using the alignment bracket peephole if needed (see image).

E. Repeat with Z2

Lastly, repeat the process for the Z2 rail and extrusion.
