When I turn on and warm up my 3D printer, it says “Injection heating different than expected.” And it doesn’t heat up at all; the screen says “heating is increasing,” but the temperature stays constant. If the temperature is 26 degrees, it stays at 26. My 3D printer model is Ender 3 V3 KE. Thank you in advance for your help.
Its sound like your ceramic heater on hotend is cracked, or wiring is damaged if its not heating up and still showing room temperature.
You would need replacement hotend. There may be local vendor, you can see below sku and search locally for it.
My brand new gender 3 v3 ke printer whe I’m setting it up is on that page where is testing the heating and it sits there for hours nothing changing what do I dio
