pretty much helped.

Filament Runout Sensor Feature

Simplify manage_heater

- Add BIT and TEST macros
- Add _APPLY_ macros to stepper.cpp to help with consolidation
- Consolidate code in stepper.cpp using macros
- Apply standards in stepper.cpp
- Use >= 0 instead of > -1 as a better semantic
- Replace DUAL_Y_CARRIAGE with Y_DUAL_STEPPER_DRIVERS

Cleaned typo in language_test.h Cyrillic part.

- Make separate get_pid_output(e) and get_pid_output_bed() function

short:
this script scans the first few lines from a gcode. If the line between 2 different z are greater than min_g1 this is our first layer. On this layer we search the min and max values of X and Y. With an offset we write that in a new file.

Conflicts:
	Marlin/Configuration.h

Macro indirection for stepper drivers + Support for TMC26X and L6470 Stepper Drivers

update

Improve description in Configuration.h

The max acceleration limiting was in wrong place.

Added option to set Travel Acceleration (non printing moves).
The M204 options was a non sense (S for printing moves and T for retract
moves).

It has been changed to:
P = Printing moves
R = Retract only (no X, Y, Z) moves
T = Travel (non
printing) moves

I will add this info o G-Code wiki in reprap.org. I also advise to put
this info in Marlin next version changelog.

I forgot to enclousure the variable with #ifdef
