]]>The E3D has solved my problem, but really: double check your z-offset first. You should make it lower than its current value (not higher as someone else said earlier in the thread). Just as a way of testing this out, try setting it to 0.0! You'll get no adhesion, but if it extrudes OK then that's your issue.
]]>I have the same problem.i try everythink but nothing.
just when I posted some advices I had that problem. The idea that I am going with is the high temperature of the inside. I print now with the upper door open and the front one closed. The upper one stands on the front door, thus leaving some space up for some fresh air to come. Try this.

I left some out, since we're talking specifically about Press with ABS. Try ruling out the easy things first so you don't make things worse rather than better. (For example, reassembling the heater block too high on the heat break pipe will overheat the bottom of the extruder and the top of the heat break tube.)

Where is the filament supposed to be getting hot? When I put filament in to force some out it seems to melt in the A section of the picture...
The narrow bit at the bottom of A is the "heat break". Above this, filament should be below Tg (glass transistion temp). The extruder body acts as a heat sink to keep the top of A "cool". When you take the tube out of the extruder body (as pictured), A will not stay cool.
If you heat the hot end outside the extruder, it will melt plastic above the heat break. Be sure to remove/purge any melted plastic from above the heat break, as this will harden and cause problems for normal extrusion. (Purge with a 1.5mm Allen wrench, or the back end of a 5/64 drill bit. Hot! Carefully.)
Things to check: the drive wheel is lined up front-to-back with the rest of the extruder.
Could also have some junk in the nozzle. A few ways to tackle that are bring the extruder up to temp, then turn off the heat and let it cool to 160C and pull out the filament. Ideally this pulls out a little swollen plug of filament, which was the melt pool. With luck, a little clump of something is in there. (If the filament snaps inside the tube, then the temp was a little cold. If the end necks into a long string, it was a little hot. Adjust and repeat as needed.)
