6.2.9 First layer calibration
Now we will finally calibrate the distance between the tip of the nozzle and the probe.
Check if your print surface is clean!
You can find instructions on how to clean it
in the chapter
6.2.2 Flexible steel sheet surface preparation
. Don't forget to
complete
6.2.5 Calibrate XYZ
chapter or
you can permanently damage the print
surface
!
You can launch the calibration from
LCD Menu - Calibration - First layer cal.
The printer will probe the bed and start printing a zig zag pattern on the print surface. The
nozzle will be at the height based on the PINDA probe setting, it must not by any means
touch the printing surface.
Pict. 10 - How to tune the nozzle height live during the test print. Note: -0.640 mm is only for
illustration. Your setting will be different!
Observe the line which is being extruded on the print surface. A new menu will automatically
show up where you can tune the nozzle height live during the test print. The aim is to lower
the nozzle until the extruded plastic sticks nicely to the bed and you can see it is being
slightly squished. The value set should not exceed -1 mm.
If you have to adjust it more,
move the probe slightly higher.
