Quick guide on converting FlashForge Creator Pro running Sailfish firmware to the Marlin firmware. Not intended for faint of heart. This guide is not 100% complete and it stands here a reference for future development.
DISCLAIMER: By using this guide you are fully aware of the risks involved by such modifications. I hereby take no responsibility for any loss and/or damage to property and/or personnel involved. DO THIS ON YOUR OWN RISK.
Any compatible programmer such as USBasp or ArduinoISP will be sufficient for this modification. I recommend using AVRDUDESS as this will make this task easier.
First thing is to gain access to the motherboard of your 3D printer. Easily achieved by loosening screws on the printers bottom. Once that is done and cover carefully removed you can proceed to the following steps.
Note: All preparation flashing is done by AVRDUDESS.
If all flashing was successful restart the board by pressing the reset button near USB connector. Now your board is ready to receive Marlin firmware.
Under the assumption that you've installed VSCode, PlatformIO and git clone Marlin git repository to your desired folder by navigating to it, right click - Git Bash Here, once in terminal invoke a command
git clone https://github.com/MarlinFirmware/Marlin.gitNow fire up Visual Studio Code and open a Marlin firmware folder with it. Go through the Configuration.h and Configuration_adv.h and configure things you desire. Compile the code and upload it to your FF_CreatorBoard.
Happy printing. ketukil
