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.

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.

Printer will likely work, but the bed leveling may be compromised and the skew of the
X/Y axes may not be fully corrected. It is recommended to adjust the positions of the
Y threaded rods in the Z frame as in cases 6) to 8).

During the mesh bed leveling procedure, the following errors may be reported on the display.
1) Bed leveling failed. Sensor disconnected or cable broken. Waiting for reset.
Verify, whether the PINDA probe cable is plugged into the RAMBo board correctly. If
it is the case, the PINDA probe is broken and it needs to be replaced.
2) Bed leveling failed. Sensor didn’t trigger. Debris on nozzle? Waiting for reset.
This is a safety check to avoid the nozzle to crash into the print bed if the PINDA
sensor stops working or something goes wrong with the printer mechanics (for
example, a pulley slips). This safety check may be triggered as well, if the printer has
been moved to an uneven surface. Before doing anything else, make the Z axis level
by going all the way up and try again.
At the end of the X/Y calibration, the printer measures the reference height above
each of the 9 bed sensor points and stores the reference heights into a non-volatile
memory. During the normal bed leveling, it is expected that the PINDA probe triggers
not further than 1 mm from the reference value, therefore the nozzle is not allowed to
move more than 1 mm below the reference value during the bed calibration.
If you moved the printer, you may need to re-run the Z calibration to sample new
reference Z height values reflecting the twist and bend of the table surface the printer
is sitting on. If that does not help, please verify, that the PINDA probe is aligned with
the sensor points on the print bed during the bed Z calibration. The alignment shall
be ensured by the automatic X/Y calibration routine. If the PINDA probe is no more
