to the Z end stoppers and to re-calibrate the 9 bed point
reference values after the printer has been re-seated or transported.
New "Mesh Bed Leveling" function was added to the menu, doing what
the "Calibrate Z" was doing before.
Clean-up of some hard coded constants.
Fixed line edit error introduced in the preceding check-in.
Enable a high power mode when first booted up on a virgin RAMBo board.
1) Fix of stepper control timing
2) Load / restore baby stepping after 9 point bed leveling using
the planner instead of the questionable baby stepping routine.
Improvement of the menu system: Use a shared menuData union to preserve
memory. Adaptation of baby stepping and edit menus to menuData.
Improvement of the "Toshiba FlashAir" status display. Don't force IP
address query on each display refresh when in the "Support" menu.
Bugfix of the baby stepping menu: Show the correct value instead
of zero when the baby stepping menu is entered.
New feature: Bed leveling adjustment at left / right / front / rear side.
The bed adjustment feature is accessible from the Settings menu
and as L R F B codes of the G80 code.
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.
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.
"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.
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.
