Furthermore the more you use the Marlin firmware, the easier it becomes. Nonetheless if you are new to the process, follow the guides step by step and you will be fine. The SKR V1.4 Installing Marlin 2 guide is a guide to help get you going with the specifics needed for the SKR V1.4 3D printer mainboard. While not intended as a full guide on. Setting up the SKR V1.3 with Marlin 2 can initially be a daunting task. However, to make life a little easier for those new to the SKR V1.3 we have created the SKR V1.3 Marlin 2 Setup guide to aid in the specifics to help get you on the right tracks.

Here's a quick guide how to compile your own Marlin 2.0 firmware for the A5S and A1.
This guide is for PC only. Need help for Mac? Post below and I'll guide you.
  1. Download and install Python 2.7.
  2. Download and install Git.
  3. Download and install GitHub Desktop.
  4. Download and install VSCode.
  5. Open Github desktop, and clone a new repository.
  6. Use the URL: https://github.com/pinchies/Marlin.gitBroken!
  7. Use the URL to clone: https://github.com/MarlinFirmware/Marlin.git
  8. After cloning, switch the branch, and choose the 'bugfix-2.0' branch (important!!)
  9. Copy the correct 'Configuration.h' and 'Configuration_Adv.h' files for your printer, from the /Github/Marlin/config/examples/JGAurora/ folder, and place them in the /Github/Marlin/Marlin/ folder (alongside the Marlin.ino file), replacing the existing files.
  10. The firmware source code will then start to download. When finished, you should now have a folder:
    /My Documents/Github/Marlin
  11. Open VSCode, and install the PlatformIO plugin. Detailed instructions are here. It may take some time to complete the installation as various components are download and compiled. You will need to restart VSCode once this is completed.
  12. Open the Marlin folder as your workspace.

  14. Compile your project, using the Build button. It may take some time as various components are download and compiled.
  15. You will now have compiled firmware, ready for use! You can find the compiled firmware in the main Marlin folder, inside an hidden folder: DocumentsGitHubMarlin.piobuildjgaurora_a5s_a1
After compiling the firmware, there will be two files:
  • firmware_for_sd_upload.bin.
Mac

Installing the firmware via SD Card

The file firmware_for_sd_upload.bin, is ready to go, and can be put onto an SD card for automatic flashing. This process is 100% reversible, and you can load the factory firmware back on, at any time.

  1. Place the bin “firmware_for_sd_upload.bin” onto the SD card.
  2. Turn off the printer, and unplug it from the wall.
  3. Insert the SD card.
  4. Plug in and turn on the printer. Flashing will occur automatically.

The file with bootloader is only to be used if flashing a blank motherboard, as it includes the bootloader that is responsible for handling the SD card upload process. This means there is nothing to worry about if you want to experiment with creating your own firmware without the bootloader, as you can reinstall it later on. To flash the full firmware you will need a SWD programmer (a ST-link clone off ebay costs $5 or less).

Flash Firmware via ST-Link

To use an ST-link to upload firmware:

  1. Connect the GND, SWDIO, SWCLK pins on the motherboard, with the ST-Link. Do not connect the 3.3V pins.
  2. Then, plug the printer into your computer with a USB cable.
  3. Download and then install the ST-Link software tool (STSW-LINK004). Free registration is required.
  4. Open the program, STM32 ST-LINK UTILITY.
  5. Load the desired .BIN file, with bootloader.
  6. Connect to the board.
  7. Select the option to start flashing.
  8. Wait for flashing to complete..
  9. Success! You've flashed your firmware.


More Info

The A5S and A1 are powered by the same motherboard. The only difference between these printers, is that the x-axis is reversed on the A1, so the motor directions must be changed. This also means that homing occurs to X-max, rather than the traditional X-min. The only other differences are minor geometry changes since the A5S and A1 differ in build volume.

Original A5S Source Code

JGAurora released the source code for the A5S in late 2018. These files can be download here.
The original factory JGAurora firmware is based off the open source Dlion firmware project. That project which was an implementation of (a very old version of) the Marlin firmware, within a OpenRTOS project, with a touch interface. JGAurora created their current firmware from this project, but changed the interface side substantially. For more into this topic, you may want to read this blog post about the Dlion firmware. It is still actively used in some 3D printer models today!

Before reading this article, you should have already read Installing Marlin with PlatformIO.

PlatformIO turns VSCode into a complete IDE for compiling and developing Marlin.

Installation

1. Install VSCode

Visit the Setting up Visual Studio Code page to download and install the latest VSCode for your particular platform.

2. Install the PlatformIO IDE

Head over to the “Get PlatformIO IDE” page to learn how to install PlatformIO IDE in VSCode.

(The quickest way to get started is to install Auto Build Marlin and PlatformIO will be installed along with it.)

Open Marlin in VSCode / PlatformIO

Marlin Firmware For Mac Os

You can open Marlin in Visual Studio Code in one of several ways:

  • Drag your downloaded Marlin Firmware folder onto the Visual Studio Code application icon, or
  • Use the Open… command in the VSCodeFile menu, or
  • Open the PIO Home tab and click the “Open Project” button.

Set your environment

To manually set the environment for your board:
Open the file platformio.ini and change default_envs to the environment that your board uses. Look through this file for your chip’s environment name. For example, the environment name for the LPC1768 chip appears as [env:LPC1768]. Omit the outer wrapper: [env:____].

When you click the PlatformIO button, you will see the PROJECT TASKS including Build and Upload. These buttons will build and upload your default environment.

If you don’t want to set default_envs, select the environment for your board from the PlatformIO Project Tasks list.

Identifying your board’s environment

The PlatformIO environment needed for a motherboard is in the comments for the board in the pins.h file. In Marlin 2.0 it’s located in a subdirectory Marlin/src/pins/pins.h.

Search the pins.h file for RAMPS_14_EFB until you come to the following:

The env:xxxx section(s) are the PlatformIO environment(s) that are used for this board.

6. Initiate Build, Clean or Upload task

Marlin Firmware For Cr10s

Initiating a task is done via PlatformIO’s Project Tasks, the bottom Status Bar icons or the Auto Build Options.

Working with the build window is a little bit better than shown in Installing Marlin with PlatformIO.

  • The panel can be re-sized.
  • The console can be scrolled via the mouse scroll wheel or with the scroll bar.
  • Text can be highlighted and copied to the clipboard.

‘firmware.bin’ file

Some newer boards require the firmware.bin file to be copied onto the onboard SD card, and then you must reboot the printer to complete the install. PlatformIO will try to copy the file automatically if the board is connected and your PC can see the SD card, but this may not always work.

In these cases, you’ll need to locate the firmware.bin file and copy it over to the SD card manually.
