Hi just a quick question. After I did a bed mesh and saved it to the default profile is it automatically apllied when I start printing? Or do I need a G29 L1 type of command? I’m sorry to say but the documentation misses a lot of basic stuff and it’s hard to find qucik answers to simple questions like these.

The Bed Mesh module may be used to compensate for bed surface irregularties to
achieve a better first layer across the entire bed. It should be noted that
software based correction will not achieve perfect results, it can only
approximate the shape of the bed. Bed Mesh also cannot compensate for
mechanical and electrical issues. If an axis is skewed or a probe is not
accurate then the bed_mesh module will not receive accurate results from
the probing process.
Prior to Mesh Calibration you will need to be sure that your Probe's
Z-Offset is calibrated. If using an endstop for Z homing it will need
to be calibrated as well. See [Probe_Calibrate](Probe_Calibrate.md)
and Z_ENDSTOP_CALIBRATE in [Manual_Level](Manual_Level.md) for more
information.
## Basic Configuration
### Rectangular Beds
This example assumes a printer with a 250 mm x 220 mm rectangular
bed and a probe with an x-offset of 24 mm and y-offset of 5 mm.

The default mesh is loaded upon Klipper start. No need to load or activate.
If you want to generate profiles depending bed temperature (something I’d recommend) then save your mesh with:
BED_MESH_PROFILE SAVE=name
and load it, e.g. in your slicer’s start code with:
BED_MESH_PROFILE LOAD=name
Note: Every run of BED_MESH_CALIBRATE will replace your default regardless if you save it under a new name or not.

That’s a nice tip. Will surly do that. Thanks.
