Prusa i3 – Build Manual
11.6 Bed Levelling Preparation
If you have carefully performed all the steps from 11.5 you can confidently now perform a full auto-home, test
that now and allow the Z-end-stop to trigger this time. Note the distance from the hot-end nozzle to the
aluminium surface, it should be at least 8 or 9mm enough to comfortably fit the mirrored surface through, see
Fig 11.6a (Note pictured is a J-Head hot-end but same procedure with the MK8)
Fig 11.6a:
Now select Prepare → Raise Print Head from the LCD menu and clip your mirrored surface onto the heated
bed using the crocodile clips and tighten up your front two nylon spacers (unless your using 4 springs). Also
tighten up the z-axis endstop trigger screw to increase the height slightly of the hot-end nozzle after auto-home.
