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. 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. The script is setup by default to build the Marlin fork “Skynet3D” for the Anet A8 Prusa clone.
Recently Anet A6/A8 support has been merged back into the main Marlin branch. You can find example configurations for Anet printers in the Marlin sources at: github.com/MarlinFirmware/Marlin/tree/1.1.x/Marlin/example_configurations/Anet
If you want to build stock Marlin change the “marlinRepositoryUrl” parameter respectively.
If you build for non Anet platforms you can 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.
