Step 12.26 — 350 mm: [quad_gantry_level]¶
Step 26 of 37 · Chapter 12 — Software: Pi OS image, Klipper/Moonraker/Mainsail, firmware, printer.cfg
(no image — see text)
Parts: none.
Do: Uncomment the 350 gantry_corners and points blocks. Both keys need their continuation lines uncommented too, and the indentation must survive.

Check
gantry_corners has exactly two coordinate lines and points exactly four, all indented by three spaces.
What you're looking at
QGL, quad gantry level, probes four points and drives each of the four Z motors independently until the gantry is parallel to the bed. gantry_corners says where the gantry's pivots are and points where to probe, both specific to a 350.
Klipper errors loudly if a continuation line loses its indent, so a bad edit here fails at Step 12.37 rather than silently.
