Ender 5 pro Beeping on start up



  • Hi, the other day I was changing the nozzle and while heating up the machine started a loud beep.
    Googling turns up to update the firmware. I did. It still does. facebook groups says to check thermistor, I replace and it still does it.

    Ender 5 pro stock except for microswiss direct drive and all metal hot end. Heater cartridge replaced 6 mo ago. THermistor replaced yesterday. (as well as 6 mo ago) Machine has been a WORK HORSE for 2 years with minimal issues. and was printing fine for the last few weeks.

    Suggestions????
