Update- updated firmware problem solved

Thanks for asking this question. I too have been having this problem and got mad and went back to PLA thinking I wasted $2500. Thanks alot gr5! I see the problem there, the nozzle is just heating up to quick with the new 35W heater. For myself, I'll go with preheating, as you said, so it doesn't "overjump" these 275C. But I'm afraid that people new to 3d printing just get this error everytime they try to print with the ABS profile. They'll follow the error message, go to the support faqs, check the cable connections as told and are lost, and may returning their UM2+ just because of this silly firmware-bug. That should have turned up first in Lab when Ultimaker ran through their tests... I'll contact the support on this matter, this should be a easy one for them to correct in a new firmware. Thanks again for your quick reply! That's the main reason i chose ultimaker, a solid community is essential

Purchased my UM2+ last week. I got this error every time i try to print with stock ABS settings. When my heater goes over 270c since it won't stop at 260c.
