Works! But parameters need to be optimized!

About this Fork

This fork is a Marlin version, based on the original branch of MKS (board manufacturer), and was created to bring Marlin 2.0 with the easy configurability of Marlin implementation from l3tspeak to TwoTrees printers like the Sapphire Plus an Pro.

Preconfigured printers:

  • Sapphire Pro
  • Sapphire Plus
  • Bluer
  • Sapphire Pro/Plus with E3D Hemera

As I own a Sapphire Plus with Hemera, this will be the only tested version.

Some other Recommendation

I'm using the Cura for slicing with the Voron 300 as base-profile. Some configurations had been made.

Mks-Robin-Nano-Marlin2.0-Firmware (Description of original project...)

Features

The firmware of Mks Robin Nano, based on Marlin2.0.x, added the LittlevGL, supporting colourful GUI and touch screen. It is developed on PlatformIO, we hope more and more developers will participate the development of this repository.

Build

As the firmware is based on Marlin2.0.x which is built on the core of PlatformIO, the buid compiling steps are the same as Marlin2.0.x. You can directly using PlatformIO Shell Commands, or using IDEs contain built-in PlatformIO Core(CLI), for example, VSCode and Atom. VSCode is recommended.

About the gcode file preview

The images should be added to gcode file when slicing, and MKS has developed the plugin for Cura to make it.

About the image conversion

  • Open LVGL online image converter tool.
  • Open bmp images.
  • Enter the saved file name.
  • Choose color format:True color.
  • Choose file output format:Binary RGB565.
  • Start convertion.
  • Save bin file.
  • Copy the converted bin file to the assets folder.
  • Copy the assets folder to the SD card.
  • SD card is connected to the motherboard, and you can see the update interface after powering on.

Firmware Can be run on Robin Nano V1.x and V2.x boards

MKS Robin Nano V1.x build and update firmware

  1. Build config:

  • platformio.ini:
