Hello,
My Ender 3 Pro had been out of commission for over a year due to a printing issue: the extrusion stops even though the extruder motor seems to be straining (“click, click, click…”).
Determined to fix this problem, I started by installing a new aluminum extruder, which didn’t improve things.
I scoured the forums looking for another solution and tried calibrating the extruder.
A new problem arose while I was performing this calibration (using the “Control” menu to feed the filament 10 cm): the screen started flashing at the same time as a repetitive beep sounded.
You can see this issue in this short video: https://www.youtube.com/shorts/rPHT6FYRvG0
Do you have any ideas?
I tried booting up while disconnecting certain peripherals, such as the temperature sensor, but I wasn’t able to resolve the issue.
