I have an i3 2020 I purchased in 2015. Done a few mods but I'm looking for a modern build of marlin with the safety features active as well as bl touch and graphic LCD. Also looking for a good way of mounting bl touch on the factory extruder. I currently have an ft5 fang cooler on it.Any help with these would be great!!
I would start with the firmware for the i3 Mega and adjust the X, Y, and Z max size to your printer. That should get you very close to running right away. It is 1.1.8
