Hello! I'm totally new to the 3D printing space. I have just received my AnyCubic i3 Mega and this upgrade kit to a Mega S from ebay (no affiliate link's) I have calibrated my extruder and it's already printing 100 times better than before! But I really want to try and upgrade the firmware to some Marlin variant that has the auto bed leveling feature for even better prints. I have been searching a bit and some say their are 4 different versions of my printer and I should watch out for what firmware I flash on it in order to not brick it.
So my question is; How do I know what version of the printer I got? And what firmware to flash on it? I have been looking a bit at the Firmware Updater and Marlin Updater plugin - but I don't know what flash method to choose in the Firmware Updater or how to install arduino-cli version 0.5.0 for the Marlin plugin. As I'm currently running Octoprint from a docker as I only have one pi, and it's running some other stuff too.
I really hope someone can help me out. I would appreciate it!
