Changed Bed correction from 4 points to 8 to get better results as we got on the MK2/s
Changed langtool.pl to have EN as default
Added tiem and credentials to support info
As per the below investigation I have tuned and tested a more robust PINDA2 Offset Calibration.
PINDA2 Investigation
Test #2 (20th Jan 2018)
Moved PINDA2 Thermistor Cal to bed centre
Moved it closer to bed from 150um to 50um
bumped bed up 5C each cycle as it wasn’t heating PINDA2 to temp at current settings
Results from a cool of 35C start

Test #3 (21st Jan 2018)
Moved PINDA2 Thermistor Cal to bed centre with measure in default firmware position.
Moved it closer to bed from 150um to 50um

or DISABLE_STEPPER_DRIVER_INTERRUPT().
If this is not done, the stepper interrupt would likely overflow,
leading to a maximum 32ms delay before the stepper interrupt wakes up.
In addition, the stepper timer overflow error would be reported
by the debug builds.
A build version and repository is displayed on the welcome screen,
D-codes, stack overflow check and stepper timer overflow check
are enabled in the debug mode.
