That's for a standard hot end not with the E3D so much.
It's a little more difficult to jam the E3D since it's all metal but if you set your retracts to high it will.

Doesn't mean it can't be done easily because I've done it all the time with
PLA if I don't have the retraction dialed in but I've never done it with ABS.

My understanding of it is that any time you leave an extruder heater on, you run the risk of scorching the material inside it, which may not clog immediately, but can build up and make it more likely to clog later, especially if this happens repeatedly. But the E3D is also much less subject to that problem because of having an all-metal one-piece interior which provides fewer places for scorched material to stick to. So you may have no problems, but you may have just made it more likely that some future time you slip and leave the extruder on too long, or even just in normal use, there'll be a clog. It's more of a death by a thousand cuts thing than an explosion.

Now, time for me to be corrected.

So I started a print before I went to bed.

Wake up to find no print and my computer logged off.

Purge E3D with 35mm filament and click print.

Ran like a champ!

Why didn't it plug up like everyone says? I thought if you left a hot end with ABS on for 10-15 minutes you risk clogging?
