Thought about using cleaning filament to clean out a bit, but may not helpful as the jam is not near hot-end. In your shipping box there should be a small bag of cleaning around.

How soon until you guys get more colors? Green would have been a good thing this time of the year.

It seems that I'm the only one who got a spool with poorly controlled filament diameter? I broke open the spool of yellow for comparison. That one looks right on the money---reads at 1.74mm to 1.75mm, very little variation.

By contrast, the spool of blue filament reads 1.58m to 1.86mm. That's a HUGE variation. You can see it in the first photo I posted. I should probably have put calipers to it first thing and tossed the blue. I was optimistic, though, after it printed the vase perfectly. But my guess is that eventually I just hit a spot that was too wide to fit through part of the extruder, and that's why I got jams. I hope it's just a one-off thing. Did anybody else get filament that looks like that?

William---I did use the cleaning filament before starting with the blue filament. I don't think it did a whole lot for me, because the hot-end is pretty new and I have only used it with PLA before. But I also last printed in white PLA, which would be a bit hard to see, since the cleaning filament is also white.

As 1.86 is more than double outside their stated spec I'd think they'd bend over backwards to replace it.

That is definitely unacceptable. Toss it and I will discuss with eSUN on what happened and why this one can get through their quality control sensors. For anyone else let me know if you have same issue.

I haven't opened my blue spool yet, but I assume it's in the same batch. Will be interesting to check it.

Just opened it and took some micrometer measurements. The section I measured was on the low side within spec (barely) - 1.74 to 1.71mm.

Update: I confirmed with eSUN that the majority average point is somewhere around 1.74mm +/- 0.03mm for 1.75mm version (spec 1.75mm +/- 0.05mm). For 3mm, the spec is 2.90mm +/- 0.05mm. They usually exceed spec.

[sprior]

I would think +-0.03 means between 1.72 and 1.78. I was going by their website spec of +-0.05 where anything between 1.70 and 1.80 is fair game.

Didn't get good stick at 90C either so I skipped 100C and upped the bed temp to 110C - that seems to have worked fine. I'll probably try 100C at some point because the time to heat the bed goes up significantly from 100 to 110.
