Hope someone may have some insight into my problem. I have an Ender 5 Plus has been running well since I got it then this. I am having a Hotend Runaway when I turn the machine on the Head starts to heat up and will not stop till I turn the Machine off. I have replaced the Hotend complete and did a PID and it failed due to high a temp . Then I just replaced the Mosfet and it does the same when I turn power on temp goes very high. PID failed due to high a temp again. Is this going to be a board replacement or is there something I am missing. The screen shows all the output when I turn it on but the Temp goes up.
Look forward to your feed back
