[old] How to upload Marlin firmware from Windows

Install Microsoft Visual Studio Code

Install PlatformIO inside MSVC.

Install Github Desktop (or your favorite flavor of git)

Clone the Marlin firmware repository. I will clone to local directory ~/Marlin/

Click on the PlatformIO plugin

Click Quick Access PIO Home > Open

Click Open Project and then

Open your copy of folder ~/Marlin/

Click here to change the current branch.

bugfix-2.1.x-polargraph-with-config is the branch installed by default on all Makleangelo 5 robots.

bugfix-2.1.x-polargraph-huge is the custom version for Huge machines. Out of the box a Huge might still have the 5 branch installed.

Click on "Explorer"

Click on "Switch PlatformIO Environment"

Choose your environment. The default env for Makelangelo robots is env:mega2560.

Compile your code to make sure there are no errors.

If your board allows and is connected, upload your code.

If your board communicates over serial USB, connect here.

Please use Friday Facts 4 to customize your firmware for other hardware, etc.

Once this is set correctly, upload the firmware again.

Makelangelo robots store some important numbers in EEPROM such as machine size. New machines have all values at zero. Old machines getting a firmware upgrade may have outdated numbers.

To set these numbers to factory default values, connect to your robot through the serial monitor and send M502, factory reset.

You can verify the new numbers with M503, report all settings.
