bubnikv 403d71d902 Increased the "calibration point not found" threshold from 0.5mm to 1.mm 
difference from the reference value stored in the EEPROM.
Lowered the speed of lowering the Z axis during the XY calibration
from 0.5mm per zig-zag search to 0.2mm to avoid the nozzle scratching
the bed if the PINDA sensor is mounted too high.
Improved the display routine to break the interpunction from the end
of a sentence. While the result may not be typographically correct,
more fits onto the screen.
