planning to run a 50hr print (the ford engine) this weekend. any tips or watch it for such long print? thx
A ups 
Hide the powerstrip switch from kids 
Netflix my man… but seriously I would set up a webcam and octoprint to remotely see it so you don’t have to keep sitting there.
Pray 
Make sure the first layer is perfect, then sit back and let the printer do its thing!
Don’t run it from a pc…
Good luck! Make sure to place a spool with enough filament on it!
Thx it will PLA print on non heated bed with zebra skin. We’ll see
Beer run first, you will surely run out 
Double check thermistor wiring, belts, and pulley set screws. Maybe even clean the the nozzle. Nothing worse than getting a jam when you’re 30+ hours into a long print. Good luck!
