I have the Ender 5 and have been using it for over a year now. I recently had a power fluctuation while on an 8 hour print. The printer stopped, showed a message on the display with "Resume" print as an option. I selected resume print, the bed and the nozzle started to heat up.
After that, nothing happened. I waited for about 30 minutes after the nozzle and be reached the correct temperature but the print never resumed.
How to fix?
