Error: One heater seems decoupled from thermistor

edited April 2016 in Questions & Answers
I've searched for the past 2 hours and I can't find or I don't understand solutions to this problem.

When I go to print, the bed heats up fine, the extruder heats up fine, but 10 seconds into the print, it gives me an error and stops printing.

"Error: One heater seems decoupled from thermistor - disabling all for safety!
Error: Could not hold temperature 225.00 measured 205.43 deg. C"

My temperature curves seem fine, until the printer starts printing, then the extruder temp rapidly drops until I get the error. 


Any help would be greatly appreciated.
