board resets mid print

[EmanueleBrotti]

hi, i managed to flash octoprint after a failed first try, because the board randomly reset mid-download, but formatting the sd and redoing the steps (switching the octroprint version for python compatibility) seemed to work. I also downloaded the octoeverywhere plugin, to monitor my printer, but after trying to print a 4 hour object, the board randomly reset halfway, disabling the printer. Is it something common with this board? If so, doesn't it make octoprint almost useless? If not, is there a power-saving option i missed, or a way for me to see what went wrong? Octoprint's logs show nothing. Anyways, you guys did an amazing job with this project, thanks for your time!
