of your suggestions, only the voltage and current could be relevant, because the rest would have resulted not in a crash like that, it's a print from SD-card afaict, making Serial port a non-issue, the file wouldn't result in a hangup, the G-code does not result in a self-reset/bluescreen, endstops are ignored during actual printing (printers use software endstops only then)

@Trish: While the serial port isn't being used for printing, it could spill useful debug output indicating the cause of the crash at the moment it happens.

+1 for serial port debugging, you could put more emphasis on that option. I am surprised that no one else mentioned this.

One thing you should fix is the attachment of the belts to the carriage; the belt (tensioned with a tie wrap is quite original) has a lot of play. This causes the layer shifts in your prints. But, I don't think this is related to the crashing.

# Printer crashes at the beginning of a print

(Asked by: username_0 on 2020-08-03)

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:
