Calibration

Here is a step-by-step calibration guide tailored specifically for the Creality Ender-3 V3 KE. Because the KE runs a version of Klipper (Creality OS), the calibration steps utilize Klipper methods.

Step 1: Bed Leveling & First-Layer (Z-Offset)

The Ender-3 V3 KE features a CR Touch and a strain gauge to calculate bed leveling and Z-offset automatically . However, you must manually tune it for perfection.

• Procedure: Run the automatic bed leveling/calibration routine.

Common defects

Auto Z-Offset Failures & The "Blob of Death"

• Symptom: The printer produces poor first layers, prints in the air, or creates a "Blob of Death" (a massive accumulation of melted plastic that encases and destroys the hotend) .
• Cause: The printer's automatic Z-offset calculation is highly unreliable, frequently setting the nozzle too high (e.g., -2.15 instead of the optimal -2.30) resulting in prints failing to stick to the bed [1, 3].
