Getting the error: Thermal Runaway, system stopped! Heater_ID: bed Which causes octoprint to panic and disconnect my printer. This happens maybe 10 minutes after starting a print, after everything is warmed up and the actual printing starts. Happens almost every time. However, when I reset the ramp
Thermal runaway can occur when the wrong PID setting are used. Thermal runaway can occur with loose wiring. Check you wiring to the Heater and Bed, Some hotbed with give thermal runaway if you use PID settings. What are your PID numbers from the LCD. What kind of 3D Printer do you have. Edited 2 time(s).

The printer is working but I keep getting issues with a "Thermal Runaway" showing on the LCD panel. I have managed to get a couple of prints without issue so the setup is generally working. I have done a PID auto tune and put the figures in the firmware but still get the issues.
Mar 3, 2015 · Also if you have a PCB heater running from 12V you don't need thermal runaway detection as even at full power the temperature is self limiting because the resistance of copper goes up rapidly with temperature. If it takes 10A when cold it will only take ~7A when at 110C and won't go much above 130C even under a fault condition.
Mar 18, 2017 · Thermal runaway shutdown is normally triggered when the temperature of the bed or extruder exceeds the MAXTEMP value. Have a look in your firmware settings and make sure that the values are suitable for the temperatures you are using during printing.
If your print cooling fan is too aggressive, it can lower the temperature of the bed enough that the controller thinks that there's a problem. I've had this happen with just a weak fan blowing across the build plate. You can fiddle with the alarm settings in the firmware to do with thermal runaway, or lower the speed of your print cooling fan.
Jan 5, 2016 · I just encountered a thermal runaway condition while attempting a print. It occurred twice and having read your post I found it quite useful. I did notice the following in the Repetier host log which I cannot explain: < 14:12:33.889 : N2205 G1 X108.382 Y136.046 E505.6926 F4800 *32 > 14:12:34.061 : ok
Recv:11:34:05.885: Error:Thermal Runaway, system stopped! Heater_ID: 0 I have of course checked al cabeling and connectors - everything seems to be fine. I also cannot imagine that it is a cabeling issue because that would happen more randomly.
Today I tested the heating again. the bed was set to 90 degrees. The bed hit 90 degrees. Then got to 92 then seemed to drop to 87.70 then the dreaded .READ: Error:Thermal Runaway, system stopped! Heater_ID: bed READ: Error: Printer halted. kill() called! So all I can think it could be with my very limited knowledge of firmwares and electronics is
Feb 17, 2015 · You can disable the test by setting THERMAL_RUNAWAY_PROTECTION_PERIOD to 0 or you can make it bigger to make it less sensitive. If your temperature is unstable you might need to tune the PID constants. Or perhaps you have a fan that cools your hot end too much.
