Step 18 of 42 · Chapter 06 — Z axis (and Chapter 06b — Gantry squaring)

Parts:
- one Z belt, first end clamped · already on the bench
Do: Take the belt tail down past the lower Z joint on the rail side, around the Z drive pulley, and back up the run further from the rail. Teeth face inward, onto the pulley. Needle-nose pliers help.
Check
The belt seats fully round the drive pulley, and teeth face each other between the two runs; teeth showing outside means a twist.
What you're looking at
The belt tail runs down the rail side of the upright and wraps the toothed pulley in the Z drive, the pulley that lifts this corner. Teeth face inward so they engage; a belt running smooth-side-on over a toothed pulley skips teeth.
