Why Does My 3D Printer Stop Extruding PLA? I have an Ender 3 V2 which is around 6 months old. Recently, extruding slowed to an almost complete halt seconds into a print for no apparent reason. The extruder works perfectly when extruding manually (using the extrude setting) and I see no reason for it to not extrude properly. I am using Ultimaker Cura and a new filament (my old one has the same issue). The print speed is 10mm/s and the temperature is correct for the filament which is PLA+. After some testing it seems random when it stops extruding but it always happens within the first 10 seconds of the print starting.

If it only extrudes the priming line, then nothing comes out for the model, this sounds like you have your slicer configured for extremely low or no flow, or wrong filament diameter. Check that any flow settings are at or near 100% and that the filament diameter in the machine, extruder, **and** material settings is correct (1.75 mm for most printers).
