+    On my custom firware, you can use the `Z Probe Wizard` feature to help performing the Z-Offset. \
+    To do so, on Ender 3 screen menu, select : `Motion > Z Probe Wizard`.

+    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. **Do a bed tramming** (a.k.a manual bed leveling). On Ender 3 screen menu, select: `Motion > Tramming Wizard`.
+    2. **Do an automatic bed leveling (ABL)**. In Octoprint, go to `Bed Visualizer` plugin UI and click `Update Mesh Now` button.
+4. Linear Advance (also know as Pressure Advance): \
+    Linear advance tunning is filament specific. \
+    For a given brand & type (PLA, PETG), you **may** use the same LA tunning. \
+    But for optimal result you should tune PA for each filament roll.
