Each time I try to print the machine stops extruding. I've cleaned the whole nozzle assembly half a dozen times, slowed the print speed, leveled the print bed several times, and it still doesn't help. The cause is a piece of filament getting jammed in the feeding mechanism for the extruder. I've included a link to a picture of the jam that continually causes the problem. Any help is appreciated.

No, it's running the whole time.
200C the whole time... fans are running the whole time. I just pulled everything apart that has anything to do with feeding the filament and made sure everything was clean. It seems like some sort of retraction issue. I tried printing with retraction off too.
There is a tube in the hotend. Here is a pic of the extruder and the original pic of the filament jam, as I realized that you probably can't see that last one.
I can't post the damn pic. I'm working on it.
The second one is on the way .... the internet is cutting out on me today too. Very bad day for tech at my house.
More info:
200C extruder temp
60C bed temp
1.75mm PLA filament
I've tried increasing flow to 110%, slowing down the print speed to 50%,
Now the extruder isn't clogging, but I'm getting horrible quality prints. Nothing adheres to the print bed. I've tried leveling the bed several times, painters tape, glue stick... I'm about out of options.
I just got a print that was better than anything else today. Not great but at least it was recognizable. I re-calibrated everything and cut the first layer speed down to like 1/4 speed. I'm thinking you might be right about the nozzle. Everything was fine until yesterday. It was having trouble pulling filament in, which I figured out was because there was too much tension on the filament because there was too much friction between the spool and spool-holder. (I had to print a new spool-holder because the stock one was too small) Once I figured that out I put some silicone on the spool holder and got a great print. Got up this morning and everything started jamming up. All I can figure is that somehow the feeder gear might have somehow gotten damaged but I can't think that filament would do anything to that, no matter how much it was grinding away. What do you think?
One thing I forgot: At times during printing it will just go all the way out to one far side of the build plate for no apparent reason. This is normally when things begin to go awry.
Mostly via USB cable, though I did try the card. If anything it seemed better with the SD card. Now I've gotten it to stop clogging, but the print quality is not good. I'm wondering if I need to change the sheet on the print bed. It's still the original one from a month or so ago. I have about 72 hours worth of printing in that time.
I'll try that, thanks a bunch for all of your help. I'm a noob at the 3D printing stuff and this forum is saving me tons of trial and error.
I am having a similar issue with the same printer, also I am brand new to printing so wanted to rebump this thread to see if there are any further suggestions.
To add to the discussion, my printer starts out fine for the first and maybe second layers, then extrusion tapers off suddenly and no further filament is extruded. I have taken apart the extruder and am not seeing any distortion to the feed as displayed by the original poster.
This problem also seems to happen quicker as I make repeated attempts which leads me to think it is heat creep related. Printing from a cold start often gives me an extra 5 minutes of printing before the extrusion stops. I have tried modifying a number of settings including extruder temp, flow, print speed, etc with no discernable improvements.
Furthermore, I have never seen my secondary fan spinning. Is there any way to test if this fan is functional? Do I need a volt meter to find out if it is getting power? I am unsure how to tell if this is a sensor problem or fan problem.
Any and all advice is much appreciated.
