Step 10.79 — Connector audit¶
Step 80 of 80 with a helper · Chapter 10 — Wiring and Checkpoint #1
(no image — see text)
Parts: none.
Do: Walk the board and press every connector home: seven stepper ports, six used, STEPPER-4 empty, TH1, X-ENDSTOP, Y-ENDSTOP, Z-ENDSTOP, Z-PROBE empty, FAN2, FAN3, LED-Strip, Vin 24V, Vin 24-48V, HEATBED, USB-C. Then the USB adapter: 24 V in, USB in, umbilical, ground.
Check
Nothing rocks, nothing is half-seated, no header pin is bent, no connector is one position off on a header.
Helper Reads the connector list aloud, one port at a time, and ticks each one pressed home.
What you're looking at
A final pass over every socket on the Leviathan and the USB adapter, naming each one aloud as you press it home. A half-seated connector and a header plugged one position across are the two faults that survive every electrical test in this chapter.
Good stopping point · ~20 min since the last one
the dead meter sweep is complete and every reading is in band. The machine is unplugged, open and ready for Checkpoint 10. Do not plug the cord in again until Ch 12 Step 12.11 — the next power-on, done with the same hand-on-the-switch ritual as 10.23.
