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 for ARM. Everything is standalone, nothing is installed.

It also works on Linux in general. If you don’t build on ARM you will have to change the architecture. Check the parameters at the beginning of the script for that.

The script is setup by default to build the Marlin fork “Skynet3D” for the Anet A8 Prusa clone. If you want to build stock Marlin change the “marlinRepositoryUrl” parameter respectively. You should also set the parameter “hardwareDefintionDirectory” to an empty string, this prevents the script from trying to copy the board definition that is needed for the A8.

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

Commandline parameters

-s  — setup

Download and configure the toolchain and the necessary libraries for building Marlin.

-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.
