The progress and results of each step are displayed on the LCD. In case of errors found, the
XYZ calibration is interrupted and the reason for error is shown to guide in troubleshooting.
At the start of the XYZ calibration procedure the printer prompts you by a following message:
"Calibrating X/Y. Move Z carriage up to the end stoppers. Click when done.”
After that, the printer asks you to confirm this step:
​ "Are left and right Z carriages all up?"
Please make sure you really move the Z carriage up to the end stoppers until you hear a
rattling sound as the Z stepper motors skip steps. This procedure ensures, that 1) the X axis
is perfectly horizontal, 2) the print nozzle is in a known distance from the print bed. In case
the Z carriage did
​
not
​
touch the end stoppers, the printer could not possibly know the height
of the print nozzle above the print bed and it could therefore crash into the print bed during
the first round of the X/Y calibration procedure.
The XYZ calibration procedure also prompts you to
​ "Please clean the nozzle for
calibration. Click when done."
If this advice is not followed and there is a plastic debris on the print nozzle, then the debris
may touch the print bed or even push the print bed away from the PINDA probe, so the
PINDA probe will not trigger properly and the calibration will fail.
Place a sheet of a regular office paper (for example the checklist
shipped with every order) and hold it under the nozzle during the first
round (first 4 points being checked) of calibration. If the nozzle catches
on the paper during the process, power off the printer and lower the
P.I.N.D.A. probe slightly. See the P.I.N.D.A. probe response diagram in
6.3.10.2 Check probe height ​ . The paper will not affect the calibration
process. The nozzle must not touch the print surface or deflect the bed
by any means. If everything went correctly, tighten the bottom nut of the
probe or it can get loose during printing later!

​ (kit only)
1) XYZ calibration failed. Bed calibration point was not found.
Calibration routine did not find a bed sensor point. The printer stops close to the bed
point, which it failed to detect. Please verify, that the printer is assembled correctly,
that all axes move freely, the pulleys do not slip and the print nozzle is clean. If
everything looks good, re­run the X/Y calibration and verify with a sheet of paper
between the nozzle and the print bed that the print nozzle does not touch the print
bed during the calibration routine. If you feel a friction of the nozzle against the sheet
