So i was building a 3d printer using Arduino mega 2560 and the voltage regulator fried, after that the screen just give blue blank screen and nothing working and when i connect the Arduino mega to the computer with the USB cable the main chip gets very hot without any load, so the question is, if i changed the voltage regulator would the board repaired or its already dead?

Hi, is there's a Software or a tool attached to some software that similar to deepnest but with more features, especially the first one: 1- telling me which parts aren't placed yet. 2- calculating the scrap. 3- calculating the unused space of the material sheet. Thanks in advance
