My Ender 3 v2 was working perfectly. I shut her down for the night, and the next morning when I started her up, I just got sustained beeping and a blank screen. From online searches, I am thinking the power on created a surge. I’m seeing things about perhaps updating the firmware to fix this, but wondering if there are other recommendations here. (I will be checking out the post here on how to update firmware, if that’ll fix it.)
Also, I am now thinking I should never shut down my machines. They are on surge protectors, but this seems to be a “surge” from startup, not from my house electricity line. Is there any way to avoid this happening in the future besides just leaving my machines on all the time?
