There’s no need to ask users to uncomment Max Endstop pins when they
have them. These will be set to -1 later if the endstop option is
disabled.

Hopefully this is helpful to organization and future expansion….

#1405 includes some changes to pins.h for a 4th extruder. This commit
applies those changes. It also deals with a possible problem with
SENSITIVE_PINS.

Hopefully this is helpful to organization and future expansion….

Add PID_dT in temeprature.cpp

Pins 2 and 3 are probably general-use pins, since the filament sensor
uses pin 2.

Replace instances of the number 13 with FILENAME_LENGTH where
appropriate.

Githun insert this line when i merge with actual Branch development...

Changes to temperature.cpp from Ultimaker fork, intended to address
#1226 and #1227

Replace instances of the number 13 with FILENAME_LENGTH where
appropriate.

Formatting for code-folding plus minor style changes to less active
code.

Done

This define is not used.

Changes to temperature.cpp from Ultimaker fork, intended to address
#1226 and #1227

Without this fix, the code wont compile with extruder but without bed
runaway protection defined.

removed function step_wait() from stepper.cpp because its used nowhere.

Issue #1385 describes a delay that the compiler is optimizing out and
this solution.

# Add: Example Configuration for Vellemann K8200 - based on new
BOARD_K8200 #1391

* K8200: new folder in example_configurations for Vellemann K8200 (3Drag
clone - should work with 3Drag http://reprap.org/wiki/3drag, too. Please
report)
* K8200/Configuration.h/Configuration_adv.h: updated manually with
parameters form genuine Vellemann Firmware "firmware_k8200_marlinv2"
based on the recent development branch

I tested the changes on my K8200 with 20x4-LCD and Arduino 1.0.5 for
Windows (SD library added to IDE manually) - everything works well

## Add: Board for Vellemann K8200 (derived from 3Drag)

* Boards.h: updated comment for board 3Drag - K8200 removed
* Boards.h: added `BOARD_K8200` with ID 78

* language.h.: machine name and firmware URL for new board

* pins.h: added `K8200` to any `#if` with `3Drag` and corresponding
comments

This reverts commit 935ee968a7.

Still not fine tuned but working.

When a melzi board and a full gfx are both selected, the build fails
blaming for some missing defines.

This is a fix for the issue: now my configuration works.

## Update Boards.h for Vellemann K8200 - comment only

* Boards.h: updated comment for board 3Drag - K8200 uses same board

This reverts commit 5333590ac2.

* K8200: new folder in example_configurations for Vellemann K8200 (3Drag
clone - should work with 3Drag too, please report)

* K8200/language.h: updated machine name and URL for K8200

* K8200/Configuration.h/Configuration_adv.h: updated manually with
parameters
form genuine Vellemann Firmware "firmware_k8200_marlinv2" based on the
recent development branch

* K8200/files by Vellemann: added folder with original files from
Vellemann homepage, since there is no GitHub fork you could link to by
them

Change default value of AVRDUDE_PROGRAMMER to 'wiring'.

Backported from Printrbot branch, allows the fan to work correctly.

G29 E was not retracting the probe on the last probe point when used with ABL grid. Corrected.
