How to provide an auto shut-down for Prusa i3 Mk2S?
1. Wired it in parallel with the power switch.
2. Use the hotend fan power as the trigger.
3. When you run a long print ,start the printer and when the hotend fan turns on (at about 50C) you can turn off the power switch.
4.The printer continues to run until the print is finished and the hotend cools below 50C. At that point the relay is no longer powered and the printer shuts itself off.
