Discussion Creality Ender 3 filament not feeding self. I bought an Ender 3 a couple of months ago and have now set it up. This is my first experience with 3D printing. When I first fed the filament into the extruder stepper I had a difficult time getting it to feed. After getting the filament to enter the first opening it seemed to get hung up at the fitting where it enters the long plastic tube.
I took that fitting off and finally got it to go on through and pushed it all the way to the extruder. When I preheated some plastic melted out of the nozzle as expected.
I'm now trying the demo that comes on the micro SD card and it appears that the filament isn't feeding. When I start printing a little plastic comes out and then stops before the first layer is completed.
When I touch the filament at the extruder stepper I can feel the stepper actuating. I guess it's trying to feed it, but it isn't actually getting pushed through. When I stop printing and raise the extruder head no plastic comes out, but when I push the filament through at the stepper melted plastic comes out of the nozzle again. Any ideas on what the problem might be? I preheated as directed to I guess that's F? EDIT: I've had time to take a closer look at the extruder stepper.
The problem appears to be the bronze piece with the teeth which feeds the filament. While the unit is printing the toothed part moves forward and then backwards so the net effect is that the filament is not being fed. The plastic that comes out of the nozzle is extremely thin and eventually is nonexistent as what ever filament is in the extruder is used up. EDIT2: In case someone in the future finds this post I wanted to add that I fixed the problem by taking the cover off the control board and reseating the 5 pin E connector.
I played around with switching the E connector with the one beside it can't remember if that was the Z and running the printer dry no filament to see what the E stepper would do and it ran fine with no back and forth jogging. It ran faster, but the pot was turned up higher on that leg. The big difference though is that the Ender 3 runs off of 24V and the board in the video is 12V. The E pot on the Ender 3 will be higher than the other 3. The E on mine was. I did not mess with those, but that explains why the E stepper ran faster when plugged into another connector.
After all of that I rechecked the E stepper when it was plugged into the right connector and it move properly. I can only conclude that the connector was loose since I didn't change anything else. It's running the demo right now and everything seems fine fingers crossed!
Has the toothed wheel which grips the filament taken a "bite" out of the filament? As a note, almost all temperatures in 3d printing are celcius. Are the teeth on the extruder gear above or belo the area where the filament runs? Mine kept coming loose halfway through a print and stop extruding even though it was spinning. The filament is about in the middle of the teeth.
After I fix the Z limit switch wire that is apparently broke I'll run it again with a mark on the filament to see if it's feeding. I found a youtube video of a guy with the same model who had a problem with the feeder as well. I'm not sure if his problem was the same as mine yet though. I just set mine up today and spent the past hour trying to troubleshoot the same issue. Going to give this a shot tomorrow! Really hoping it works for me. I just got mine like a week and have the same issue.
But i gave it a shot, i use the smallest allen-key to tighten the toothed wheel there's two black screw or something on the wheel, so tight those screw and voila fixed the issue. I had this same problem just now. The bronze toothed wheel that is supposed to drive the filament had dropped. I solved this by opening the clip to let filament in, raising the bronze wheel and aligning one of the black screws with the flat part of the axel it sits on, then tightening both screws.
I just purchased my Ender 3 and have not been able to get anything to print so far. I've checked all the screw and attachments and everything seems good except for the filament feeder. It wont turn at all. Ive opened the control box after seeing how you fixed your problem and my wiring doesnt match the description or picture you've posted here..
