I bought an Anet A8 Plus in January. Everything worked pretty well until one week ago. When I tried to print something, I got a "Heating Failed" error, as the hotend didn't get hot. I've made some search on the web, and I tried to use the bed connector on my motherboard, and the cartridge started to head. So I connected the hotend heater again to the hotend connectors.
I conclude the hotend connector may be broken, but this morning, it succeeded to heat my hotend (and then didn't work again). Can someone help me to understand what's wrong with it?
I also noticed that a LED power off when the cartridge's wires are connected (the D8 LED)
