New here so thank you for the opportunity. Brand new Ender 3 V3 SE was working fine until after a long print. Now it doesn’t work. I replaced the nozzle per video instruction and cleaned. Now the filament doesn’t heat or melt. I cannot seem to feed the filament down to reach the heating element or the heating element is not operating. The nozzle is heating the printer is otherwise working but I can’t get the filament to melt or extrude. My son and I are new to 3D printing but we’re trying to learn. Appreciate any suggestions I’ll keep investigating other topics on the forum for education and similar programs.
You might have filament stuck in the heatbreak or the extruder that is blocking the path.here is as good a youtube video as any giving the steps.
This helped! Thank you. Good video I didn’t know about.
