[Solved] Ender 3 Pro Makes Loud unending beep when preheating
I have an Ender 3 Pro That is several months old. I recently encountered an issue that when I preheat, it makes a loud, unending beep. A few seconds later, it restarts into a bootloop, continuing to beep. When I power cycle the printer, the bootloop is gone. This issue started when I plugged in my printer with a universal adapter, because my printer's power cable has a US plug while I have a power outlet that is UK. At first, my printer was printing well, until an hour later it started beeping, saying "Outage Recovery". When I tried to print after that, the message never showed up. Another thing to take note of is that the more I tried to print, the quicker the beeping starts. Currently I'm at the point where when I preheat I get the beeping. How can I fix this?
EDIT: The issue was solved by simply replacing the hotend.
@red909 Check the power supply if 230v or 110v is selected and get a better adapter
@mm3dmaker nevermind, i already solved this by replacing the hotend, thanks though
