this fork of firmware Marlin v.2.0.7.2 espescially prepared for 3D Printer TwoTrees Sapphire Plus (gen2) with two independent Z-axis (for each Z-axis have a dedicated driver) and with upgraded direct extruder Mellow NF-BMG Aero V6 Beware! It is not compatable with Sapphire Plus gen1 that used belt betwen two Z-axis motors and one driver for two z-axis motors or without direct extruder Mellow NF-BMG Aero V6.
- tuned for direct extruder Mellow NF-BMG Aero V6 and this mount carrier bracket for Mellow NF-BMG Aero V6 direct extruder
- enabled S_CURVE_ACCELERATION
- Marlin color UI
- enabled bed PID-control (PIDTEMPBED)
- adjusted PID parameters for hotend and bed
- UI black edition
Additional documentation can be found at the Marlin Home Page. Please test this firmware and let us know if it misbehaves in any way. Volunteers are standing by!
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.
