Improved accuracy of diagonal moves by oversampling the path discretization.
Accelerated the planner by rewriting time critical routines from floating
point to fixed point arithmetics.
Disable timeouts in the XYZ/Z calibration.
Don't modify feed rate multiplier during the XYZ/Z calibration.
Support multi screen messages in the XYZ/Z calibration - "move the Z carriages up" step.
Support up to three lines in the XYZ/Z calibration messages.
Added a new message "Measuring reference height of calibration point xx of 9".
Changed the "move the Z carriages up" message to suggest rotating the knob.
Changed the "live adjust not set" message to reference the manual chapter and section.
Remove debugging serial line output on Z calibration.
Get the status of the Toshiba FlashAir, namely its IP address.
The IP address is currently reported through an M46, but this
is subject to change and the IP address shall be shown on the display.
Update babystepsTodo atomically (disable / enable interrupts).
Disable debugging outputs on the serial line from the X/Y calibration code.
OctoPrint fix - fixes a hangup after G28: Link the G28->G80 G codes
by calling the G80 code directly without pushing it into the command buffer.
SD card driver patch to support the Toshiba FlashAir SD/WiFi card.
and Marlin does not support such file names anyway.
Serial characters with a highest bit set to 1 are generated when the USB cable is unplugged, leading
to a hang-up of the print process from an SD card.
"M115 Umajor.minor.revision-flavor" will trigger a dialog
on the display if the "upgrade" firmware version number is higher
than the current version number.
from Linear Least Squares to Nonlinear Least Squares to maintain unity length of machine axes.
Improved the scanning of the 1st row of the induction points.
at the end of the menu only.
Provided a general method for a menu function to detect exiting by a timeout.
When exiting, the menu function is called with a global variable menuExiting set.
Some errorneously removed functions were reverted.
Implemented bed skew calibration by matching a precise physical model
to the measured data using the least squares method.
Rewrote handling of the command buffer to preserve memory
and allow pushing the commands to the front of the queue.
