Step 02.02 — Learn the four Z positions before you build anything¶
Step 2 of 44 with a helper · Chapter 02 — Z drives, Z idlers, Z rails, deck panel

Parts: none.
Do:
- Memorise the corners from the front of an upright printer: Z0 front-left, Z1 rear-left, Z2 rear-right, Z3 front-right.
_abuilds Z0 and Z2,_bbuilds Z1 and Z3; each idler takes the hand of the drive below.
Check
You can point at each of the four corners and say its Z number and its hand without looking.
Helper Writes Z0 to Z3 on four tape flags and sticks one per corner.
What you're looking at
Manual p.23 shows the whole Z system: four drives at the bottom corners, four idlers directly above them, four vertical rails and the deck panel. Z0–Z3 is the naming this manual, the kit wiring and its Klipper config all share. See the glossary.
Caution
Rev D+ / LDO: this naming is what the kit's wiring and Klipper config assume — Z0→STEPPER-0, Z1→STEPPER-1, Z2→STEPPER-2, Z3→STEPPER-3 on the Leviathan. Label each motor's cable with a kit cable tag as you fit it in this chapter and you save an hour in Chapter 10. src
Tip
The hand map comes from the official CAD, not a manual page. Confirm it by dry-fitting the first drive at Z0 at Step 02.29 before any bolt goes in.
