extruder 0: temp sensor defect

aykay

Hello at all!
i have a strange problem, while i attempt to print an object. the first time i tried to print the object, no error occured. at the second time, ca. 50 % of the object has been printed, until the error appeared. After retrying, the error always appeared at the exactly same position, every time i tried to reprint the object.

The error message is: extruder 0: temp sensor defect. At the temperature measurement in repetier- host, the fall-off is very clearly, but just for a few seconds, afterwards the temperature is at the setpoint again. A few moments later, the temperature fall off again and the printer goes to "dry run mode" (or somehow). That means he's going on with the job, but without extruding filament.
After a reset of the printer, i can start the job again and in the first moment, i don't have any temperature issues.

After a few retries, i printed an other object, using the same slicer- settings, without any problems!
Then i went back to the "problem- object" and tried again, but without any succsess, and with the exactly same error. i also tried it, after rotating the object 90?? - but the same error occured.

I'm really out of ideas, maybe someone else already know this problem, or has the same issue as i do.

(sorry for the long post)

Roko

try checking your wiring.

aykay

i guess my wiring is ok, because i don't have any measurement problems with other objects. for the sensor wires, i took a shielded cable, and wired the shield directly to ground of the power supply (to avoid ground loops, and unnecessary inductance)

Repetier

The fact that it works most of the time does not mean wiring is ok. YOu can have a broken cable that has still contact most of the time but for some positions it will loose contact. Fact is that you see this error message if the resistance is near 0 or infinite so it catches a short and interruption. So unless you do something to confuse reading it is normally a starting defect that is only apparent in some positions and will increase over time.

Roko

also you mention error occurred at the same place every time on that object. perhaps you have an intermittent contact at that position (Z-height) and type of movement (infill, etc.) that causes a momentary problem with the connection at that point in time. You don't mention if it is a purchased or a DIY printer. I had an issue once where my DIY would error out with a bed Mintemp error which turned out to be a flaky connection between my arduino baord and the RAMPs board. I just had to reseat them and it was fine afterwards.
I have seen thermistors where the connection at the soldered on extension wires-to-thermistor wires comes apart but its not found until the wrapping is taken off then they seperate and need to be reattached.

I got the same message. The printer starts to heat the extruder, all goes normally but suddenly that message appear.
And I can't do nothing, I restart the printer and the message appears even when I'm not heating.
Someone knows what could be?
Actually I checked the wires and connections and all seems to be ok.

Activate logging and check where it appears the first time. Only there you find the reason for marking it defect. Knowing this really helps to fix the problem, e.g. if it is decoupling you can increase time or variance to not trigger false.
