+## Bed leveling
+
+To have a printer bed properly leveled when you make changes to the printer, here the list of operations to be done in that exact order:
+1. **Calibrate the Z-Offset**. On Ender 3 screen menu, select : `Motion > Z Probe Wizard`.
+2. **Do a bed tramming** (a.k.a manual bed leveling). On Ender 3 screen menu, select: `Motion > Tramming Wizard`.
+3. **Do an automatic bed leveling (ABL)**. In Octoprint, go to `Bed Visualizer` plugin UI and click `Update Mesh Now` button.
