Expected behaviour: while (auto)extruding the new filament, the nozzle should not move. It should move (from filament replacement position to printing position) only after the user has confirmed the successful filament replacement and extrusion.

Actual behaviour: while (auto)extruding the new filament, the nozzle moves from filament replacement position back to printing position.
So the extrusion step is mixed with the movement required to go back to the printing position.

The provided code seems to be working but probably a better fix is required.

Melzi fixes

Fixed typo where ST7920_DELAY_2 was being #defined after a check for #ifndef ST7920_DELAY_3

Sanity Check for LCD_FOR_MELZI  would fail with "Please select no more than one LCD controller option" any time #define LCD_FOR_MELZI was enabled in Configuration.h, even if there were no other LCD options enabled.

[1.1.x] Fix G3D_PANEL encoder steps, babystep label

Ideally, it should be calculated based on Z steps per unit so that each
babystep corresponds to around 0.025mm. Smaller than this is largely
insignificant for typical layer heights.

As pointed out by @marcio-ao in #7638

More featureful CR-10 configurations

* matrix names update

* symplified names

* new angle normalization

* ABC

* axis

* least squares

* recalc_delta_settings

* endstop_adj

* 0p

* bug

Fix caselight compile issues

Replaced extruder with hotend

Added option for graphical overlay for Z-offset (Resubmission of #7350 and #7586)

M111: no args reports current flags

CNC workspace planes for G5

According to LinuxCNC, G5 should throw an error if the current plane mode isn't XY.

* Add MAX7219_DEBUG to Travis CI testing

* Tweak config and use standard pin naming for MAX7219_DEBUG

* MAX7219: Apply coding standards, use macros, etc.

* Make code work...

Slovak UTF-8 translation

Fixes required for Creality CR-10

* Add Max7219 LED Matrix Debug Support

The Max7219 8x8 LED Matrix's are very helpful for debugging new code.
And for that matter, just trying to maximize printer settings without
causing stuttering.

The displays are very inexpensive (under $2.00 with shipping) and
provide a lot of help when trying to debug complicated code.

* Try to keep Makefile up to date.
