> I think the heater pulled out of the hotend. I had that happen once before and it quickly got cherry red and the firmware still thought the temp was ok. There is watchdog code in Marlin but I never used it. I;m going to take a look to see if it would catch this condition. In spite of trying to heat the temp would be dropping for more than a few seconds.

Yes it would. You can take a look on latest Marlin ([See this thread](https://forum.lulzbot.com/t/latest-marlin-firmware-for-taz-5/1743/20), it stops heating if the temperature doesn’t rise a couple of degrees after heating has started. A real reason to upgrade the FW, in my opinion…
