of paper and the nozzle is clean, you need to screw the PINDA probe slightly lower
and re­run the X/Y calibration.
2) XYZ calibration failed. Please consult the manual.
The calibration points were found in positions far from what should be expected for a
properly assembled printer. Please follow the instructions of case 1).
3) XYZ calibration ok. X/Y axes are perpendicular.
Congratulations, you built your printer precisely, your X/Y axes are perpendicular.
4) XYZ calibration all right. X/Y axes are slightly skewed.
Good job, the X/Y axes are not precisely perpendicular, but still quite all right. The
firmware will correct for the X/Y skew during normal printing, so boxes will be printed
with right angles.
5) X/Y skewed severely. Skew will be corrected automatically.
You may consider to re­align the X/Y axes (as described in the chapter
​
6.3.5.1 Y
axis alignment ​ ) ​ . Still the firmware will correct the skew during normal printing and as
long as the X and Y axes move freely, the printer will print correctly.
6) XYZ calibration failed. Left front calibration point not reachable.
Even if the printer moves the print bed to the end Y end stop, the PINDA probe
cannot reach the left front bed calibration point. Move the left Y threaded rod in the Z
frame away from you, so the PINDA probe reaches the left front bed calibration point
reliably.
​ You can find how to fix this in the next chapter ​ 6.3.5.1 Y axis
alignment ​ .
7) XYZ calibration failed. Right front calibration point not reachable.
Even if the printer moves the print bed to the end Y end stop, the PINDA probe
cannot reach the right front bed calibration point. Move the right Y threaded rod in the
Z frame away from you, so the PINDA probe reaches the right front bed calibration
point reliably.
​ You can find out how to fix this in the next chapter ​ 6.3.5.1 Y axis
alignment ​ .
8) XYZ calibration failed. Front calibration points not reachable.
Even if the printer moves the table to the end Y end stop, the PINDA probe cannot
reach the front row of the bed calibration points. Move both left / right Y threaded
rods in the Z frame away from you.
