I'd bet something else is amiss, cooling airflow or heatsink/heatblock gap related.

Cleared it out and all is well, for now.

Something can be smaller and still damage the finish on the heatbreak.

It wasn't damaged. I took great care using a much smaller bit, and only used it to grab the filament that was jammed. Plus, that wouldn't explain how it jammed the first time.

It needs to be measured a few dozen times along 10-20ft to rule out diameter issues.

It is definitely possible you damaged the heatbreak by drilling, as previously discussed.

Filament is Zen Toolworks ABS. I've measured it with calipers each time I calibrate, and it's pretty consistently close to 1.75

I had a very similar issue to you.  My E3D just kept clogging and under extruding.  It turned out, that even though I was able to use it for about 2 months with no issues at all, the fan shroud on the heat sync was put in upside down, which made it so the plastic was melting prematurely.  That might be something you could check as well.

Sure you didn't install the fan backwards? The shroud can be installed upside down just fine. I do this to make accessing the heatbkock easier, and E3D notes this is acceptable.


Well that's very interesting to hear, because I kept the fan orientation the same, and just flipped the shroud (unscrewed and rescrewed), and since I haven't had any clogs...

You should never have to do anything to the heat break of an E3D, even with a clogged nozzle.

What filament? Have you checked the diameter with calipers? Anything much over 1.85mm will jam in the heatbreak.
