This Vanilla Marlin branch 2.0.4.1 is for the Bigtree Tech SKR 1.4 turbo specifically built for the Creality Ender 3 with the following hardware:-
TMC 2209 stepper driver boards UART. Without stallguard function, the diag pins for X/Y of the driver boards will need to be bent outwards so they do not enter the socket (much better than cutting them off as per the manufacturer instructions, just make sure the Y board pin does not touch anything underneath ).
BLTouch Auto bed leveling probe enabled for the probe specific pins. Servos and Probe on the lower right of the board. Z offset 2.47 mm. Filament runout sensor. This is optional and can be turned off in the LCD.
Notable enabled features:- S-curve, Unified bed leveling, fast probing as per Teaching Tech's research and values. EEPROM saving, SD support, advanced nozzle park on pause, Neopixel LED (3 pixels GRB WS2812b). Photo Gcode, TMC debug and cancel objects.
There is a precompiled firmware in the root Marlin directory.

Marlin 2.0 takes this popular RepRap firmware to the next level by adding support for much faster 32-bit and ARM-based boards while improving support for 8-bit AVR boards. Read about Marlin's decision to use a "Hardware Abstraction Layer" below.
Download earlier versions of Marlin on the Releases page.

Marlin is published under the GPL license because we believe in open development. The GPL comes with both rights and obligations. Whether you use Marlin firmware as the driver for your open or closed-source product, you must keep Marlin open, and you must provide your compatible Marlin source code to end users upon request. The most straightforward way to comply with the Marlin license is to make a fork of Marlin on Github, perform your modifications, and direct users to your modified fork.
While we can't prevent the use of this code in products (3D printers, CNC, etc.) that are closed source or crippled by a patent, we would prefer that you choose another firmware or, better yet, make your own.
