Overtemp error

I have a Lulzbot Taz with budaschnozzle and am trying to print ABS at 230 degrees. As soon printer temp creeps to 235 then I get overtemp error and system starts to cool down. Any thoughts on what might be causing this?

Reach out to the support team at LulzBot.com/Support. Include information on the TAZ version and firmware version numbers. The firmware does have an overtemp setting, the support team can help you determine why your printer is hitting that, and can help you with PID tuning to better adjust your heating curve.
