Printer Crashes at the Beginning of a Print I am converting an old Makerbot Replicator 2 to Marlin Firmware and everything works. The printer heats up, auto bed levels, and starts the print. However, after a couple minutes (usually after the 1st or 2nd layer), the printer crashes and stops. It does not continue printing and I have to restart it again. It crashed for every single print, I have not had any successful prints yet.
Here is a video showing the issue:

                
            
The camera was started right when the print started. After about 1.5 minutes, the printer crashes, and the lcd screen freezes.
Here are photos of a couple of prints that crashed:

I have all of my code here: https://github.com/RosalieWessels/Marlin_MakerbotReplicator2
My models are sliced with Cura and printed in PLA.
I tried hotend temperatures of 200, 210, and 220 degrees. My print speed is around 50 or 60 mm/s.
Here is a sample sliced file that was used:

Thank you!
I see a couple likely culprits for a hardcrash like this

problems with the power supply. If the power supply does not provide enough voltage an/or current to the board, this can lead to a lockup of the board.
temperature issues of the board. If the board overheats, it could fail to execute properly, leading to abort. make sure that the board is not overheating.
faulty firmware. recompile your firmware and reflash it.
