This is why I wanted to sleep on the code I wrote while falling asleep
rather than immediately submitting a pull request.

temperature.cpp: Actually use OVERSAMPLENR in the oversampling calculation.

Enable basic ULTRA_LCD screen w/o encoders and menus.

Format README.md with subsections

Having actual section headers instead of just bold text makes those parts of the document individually linkable.

Fix bugs in Extruder Runout Prevention, including DAMAGING HEAD CRASH

This seems to defeat the purpose of previous_millis_cmd, preventing the
time elapsed from previous_millis_cmd from ever reaching
max_inactive_time or stepper_inactive_time while the heat was on.

Fixes a bug in the Extruder Runout Prevention feature that caused the
extruder to move back to “current_position” after a move if it was
activated while the move was in progress. For long home moves (which
are longer than the dimensions of the machine’s working area), this
would cause the machine to crash into the far end of its travel after
homing. This usually occurred on the Z axis, which could result in
damage to the machine if you don’t hit the reset button in time.

Update ConfigurationStore.cpp

Unable to compile if ENABLE_AUTO_BED_LEVELING is not set (not set by default).

Improvements to the auto bed leveling feature

Conflicts:
	Marlin/Configuration.h
	Marlin/Marlin_main.cpp

This is the recommended approach for object initialization. The change
doesn't affect binary size (although in theory it could make it smaller).

Correct missing parameter from last upmerge

Z and Y dual stepper drivers error

if you try to enable Z_DUAL_STEPPER_DRIVERS the error "You cannot have dual drivers for both Y and Z" shows even if you don't have defined Y_DUAL_STEPPER_DRIVERS and don't let you compile the firmware

to solve this problem i change this line:

#ifdef Z_DUAL_STEPPER_DRIVERS && Y_DUAL_STEPPER_DRIVERS

to:

#if defined (Z_DUAL_STEPPER_DRIVERS) && defined (Y_DUAL_STEPPER_DRIVERS)

now the error only show if you define both Z_DUAL_STEPPER_DRIVERS and Y_DUAL_STEPPER_DRIVERS

Added support for Cheaptronic v1 electronic

Removed the calculation of the inverse matrix since the rotation matrix is orthogonal, therefore inverted == transposed.
Much simpler and mathematically robust.

In some cases the Bed Heater FET heats up more then stepper drivers, so
this change add the bed monitoring to the controller fan. As soon as the
bed heater is turned on, the controller fan will run as well.
