Step 25 of 54 · Chapter 13 — Initial startup

(no image — see text)

Parts: none.

Do:

  1. Send SET_STEPPER_ENABLE STEPPER=stepper_x ENABLE=0 and SET_STEPPER_ENABLE STEPPER=stepper_y ENABLE=0, never M84.
  2. Push the toolhead by hand to the front-left corner. If it binds before the nozzle reaches the corner, stop.
  3. M112 ready, G28 X Y, then jog to X0 Y0, watching for skipping near the corner.

check Check

The nozzle sits over the plate, within about 5 mm of the front-left corner, with no skipping on the way.

What you're looking at

0,0 is the machine's origin: the nozzle position Klipper calls X0 Y0. It is set indirectly, by telling each axis how far its endstop sits from that origin, which is why position_endstop and position_max always move together.

Symptom Fix
Nozzle too far into the bed Increase position_endstop and position_max together, on that axis only. +2 mm on [stepper_x] moves 0,0 2 mm left
Nozzle beyond the bed edge Decrease both together

tip Tip

binding before the corner is racking or a mechanical fault, not a config problem. FIRMWARE_RESTART after any config edit, then re-check.
