Man 220 is even high for pla. Usually pla prints at 180-190. Have you ever verified the true temp at your nozzle? Do you only print pla? I have found when switching plastics some dont like to mix together right and never completely purge from the tube and nozzle which makes it tight for the new filament. You need to pull your tube and nozzle and soak it in paint stripper for a few hrs. It will melt all the buildup then you can clean it all out. The perfect sign of that happening is having to up the temps to keep it extruding correctly. Just a thought.

For this abs 235 is well within normal print temp so no big deal really. Its just a little higher than the other ones i have used. This seems to be bonding much better now. So far this stuff is printing great. In the morning i will set up an all day print for tomorrow with it.
