HowTo build the Marlin 3D Printer Firmware on the Raspberry Pi

If you are already running the excellent octoprint as a printserver on a Raspberry Pi it is very convenient to also build Marlin on it. The new Raspberry Pi Zero W with onboard wifi is at only 10$ just perfect for both tasks. If you want to use the camera streaming of octoprint I would recommend a Pi3 though.

I made a script that sets up the necessary build environment and provides commands for building and uploading. It uses the official Arduino toolchain. Everything is standalone, nothing is installed outside the marlintool directory.

It works on the Raspberry Pi and Linux in general but not on OSX. The script auto detects the build platform architecture. At the moment Linux 32 Bit, 64 Bit and ARM are supported.

Several parameters at the beginning of the script allow to adapt it further to your needs. Recently Anet A6/A8 support has been merged back into the main Marlin branch. I would highly recommend to switch to the official Marlin branch from now on. You can find example configurations for Anet printers in the Marlin sources at: https://github.com/MarlinFirmware/Marlin/tree/1.1.x/Marlin/example_configurations/Anet. Just replace the “Configuration.h” and “Configuration_adv.h” in the marlin directory with the files your find there for a good starting point of your configuration.

If you do not need additional hardware/board definitions because you use the ones that come with the toolchain set the parameter “hardwareDefinitionRepo” to an empty string. This prevents the script from fetching the board definition that is needed for the A8 from github.

If you are running octopi on you Raspberry you need to disconnect it from your printer before uploading otherwise the serial port is blocked.

or download directly as a zip: https://github.com/mmone/marlintool/archive/master.zip

Commandline parameters

-s  — setup

Download and configure the toolchain and the necessary libraries for building Marlin. Also fetches the Anet board hardware definition from github if specified.

-m  — marlin

Download Marlin sources.

-f –fetch

Update an existing Marlin clone.

-v  — verify

Build without uploading.

-u  — upload

Build and upload Marlin. If you are running octopi on you Raspberry you need to disconnect it before uploading otherwise the serial port is blocked.

-b  –backupConfig  [name]

Backup the Marlin configuration to the named backup.

-r  –restoreConfig [name]

Restore the given configuration into the Marlin directory.

-c  — clean

Cleanup everything. Remove Marlin sources and Arduino toolchain.

-p  — port [port]

Set the serialport for uploading the firmware. Overrides the default set in the script.

-h  — help

Show help.
