Now we will finally calibrate the distance between tip of the nozzle and the probe. Preheat
the nozzle for PLA. On the LCD menu, go to
Print from SD

Pict. 10 How to tune the nozzle height live during the test print
Observe the line which is being extruded on the print surface. Go to the LCD menu and
choose the
Live adjust Z
option. A new menu will show up where you can tune the nozzle
height live during the test print. The point is to lower the nozzle until the extruded plastic
sticks nicely to the bed and you can see it is being slightly squished.
