Step 13.12 — Lights¶

Parts: none.
Do: Send SET_PIN PIN=caselight VALUE=1, then SET_LED LED=rgb_light RED=1 GREEN=1 BLUE=1 WHITE=1.
Check
The chamber COB strips come on and all three Stealthburner LEDs light.
Helper Presses the light buttons in Mainsail and says which lamps came on.
What you're looking at
Two independent lighting systems. The COB strips on the chamber ceiling are plain LEDs on a dimmable output, switched with SET_PIN. The three Stealthburner LEDs are addressable, each with its own tiny controller, so they take a colour command rather than a brightness.
Tip
the strips are [output_pin caselight] on PE6. Colours that come out wrong rather than absent mean color_order only; the LDO config's chain_count: 3, color_order: GRBW is correct for the supplied LEDs. (survey §4.4 #12)
Good stopping point · ~40 min since the last one
the machine has been powered, Klipper reports Ready with both MCUs, all three temperatures read room ambient, both heaters proved they climb and stop, and every fan and light has been commanded on and off. Nothing has moved yet. Heaters off, machine idle.
