6.3.5 Preparing the Z Calibration
The Original Prusa i3 MK2 comes with a full mesh bed leveling feature, however for this to
work we need to first calibrate the distance between tip of the nozzle and P.I.N.D.A (
​ P ​ rusa
IND ​ uction ​ A ​ utoleveling) probe.
The process is fairly straightforward, so let’s get to it.
6.3.5.1 Checking the Y‐Axis (kit only)
For autocalibration to work properly, it is extremely important for the Y axis to be
perpendicular to the X axis. This can be easily checked by looking at the printer
from the top and visually aligning the X­axis rods with lines on the heatbed. You
can see it on the next picture. If the Y axis is misaligned, you can easily adjust the
position of the Y axis inside the frame by loosening the ​ M10 nuts ​ on the Y axis and securing
them at the newly adjusted position.
Pic. 5 ­ X­axis rods must be visually aligned with lines on the heatbed.
6.3.5.2 Probe alignment (kit only)
The first step is to mechanically set the position of the probe. The top of the probe
should be aligned with the bottom of a printed part as you can see in the picture
number 6. The position can be easily changed even on an assembled printer by
loosening the bottom nut few turns, moving the whole probe and adjusting the top
nut accordingly.
Secure the bottom nut afterwards or it can get loose during printing later!
Also the probe should be perpendicular to the print bed.
