I am not sure if this is a programming or technical problem. So please move this thread if this is the wrong section. I am actually a bit to confused where to start looking for help since google research didn't give me anything that is even in the same ballpark as my problem.
Long story short: I am using an Arduino Mega 2560 to operate my 3D printer. I haven't touched my printer in about a year do to a new job and other stuff that keept me busy. In the meantime I had to reset my computer about three times, meaning that I have lost all previous files.
Since I have got a Frankenstein printer (custom silicon heatbead, custom thermisters, nozzle ... etc.) it would be a real pain to call every single company I have bought stuff from and gather all information again and adjust all the scripts to my needs.
So my question is: Is it somehow possible to recover the data I have loaded up to my Arduino Mega and kind of "download" the files from it?
