But just to confirm, per this guide: https://support.makerbot.com/s/article/1667411136256
The cold pull portion of the guide is the most important.
Please feel free to share pictures of your pull results for feedback if your unsure.
I followed that exact guide. On more than one occasion, I've hot pulled until there was no residue left from the previous filament on the end of the (natural, non-colored) PLA, about three or four times. Then I cold pulled until not only was the tip coming out clean and perfectly formed, but I could sight down the printcore and see a 0.4mm pinhole of light straight through it. Clean as a whistle. I've also used the Ultimaker official cleaning filament. I'll do another round to show you the results.

- Try disconnecting your bowden tube on both ends and just manually push filament thru it and make sure its not being restricted.
I've tried that, and there was some friction. I've cleaned the tube out and added a couple of drops of oil to free it up. It's a trick I learned from gr8 for attempting to print TPU on an Ultimaker. If that fixes it, I'll upgrade to Capricorn tubes.

- Are you seeing any overly chewed up marks on your filament in the bowden tube during these prints? Please share pictures.
No I am not.

- Your front fan might be dirty or about to die. Just because its spinning does not mean its reaching its full speed. If this is the case it will result in heat creep which will cause flow issues.
I have a spare fan, I'll add that to my list of variables to check.

- Check both sides of your print head cable to make sure the connection is secure.
The cable end inside of my printhead comes loose with a pull, like the retention clip isn't engaging. I'll try designing and printing something to hold it in place if/when the other checks don't work.
QuoteYou said you contacted UltiMaker and Fbrc8, can I get your most recent case number? I will reach out to the Support Manager to find out what might be going on.
My request number is 65865.

Would say it looks like your having flow issues as its all tested material types.
