Pict. 9 The properly tuned first layer
6.3.9.1 Bed level correction
(kit only)
A bed level correction is an advanced feature introduced in the firmware 3.0.6 and is
designed to allow advanced users to correct for the slightest imperfections in the first layer.
This feature can be found in
Calibration
Bed level correction.
For example if the first
layer seems to be ever so slightly more squished on the right side. You can virtually lower
the bed by 20 microns on the right side. Settings are available for Left, Right, Front and
Back. The limit is 50 microns and even 20 microns can make a huge difference. When you
are using this function, do small incremental changes.
6.3.10 Finetuning the first layer
6.3.10.1 Print prusa logo
After finishing the calibration gcode, it is a good idea to print a simple object. The Prusa
gcode from the supplied SD card is a great example. The
Live adjust Z
function (described
in
6.3.9. First layer calibration
) works during every print, so you can finetune at any point.
You can see the properly tuned first layer on the images below.
Calibration might be slightly different for multiple materials. It is a good practice to
check the first layer and adjust accordingly with
Live adjust Z
when switching
between different types of filament.
