What causes to fail a big print (More than 15hours) where a small print done successfully( about within 4-5hours) without any issue?

Hello guys...Hope everyone is well during this pandemic.

I have done several small printing in my creality open box printer without any hassle but every time when i tried to print a big one ( which shows about more 15 hours to complete) its not done properly or sometimes partially.
What causes such issue? Looking for expert opinions.
Nozzle= 0.4mm, Print speed 100mm/s, Infill 13%, Filament PLA type,
Printer= Creality open surroundings

Accepted answer

There could be a lot of things, the nozzle could be hitting parts of the print (if you use prusaslicer, you can tell the printer to lower the bed every time it traverses over part of the print) it could even be something as simple as a bad thermistor or hotend. ($10 dollar replacement on amazon) but it's hard to tell exactly what is going on without any photos though, so post some photos. Best of Luck

Because the axis engines got hot and the printers didn't have cooling for it
