um2 - can i heat the nozzle above 260c ?

Recommended Posts

I have been printing for some time at 250 degrees (ABS prints) and last night when I took my hotend apart I saw that the teflon part is already deformed. The inner hole is 2.9x3.1mm... Already noticed that the extrusen speed was already noticable lower. Did not have under extrusion with 40mm/s at 0.1 layers and now I do when it is filling in large flat areas.

So I agree with nallath.
