Extruder temperature problème
-
I did inspect the cable and nothing seems to be wrong. This phenomen arrive also when the printer doesn't move. Sould I test it whit ohmmetre?
-
If it is intermittent connexion, the temperature should go to infinite value, and not drops down, isn't it?
-
Is it possible the sensor itself is loose? The wiring could be intermittent, but usually that results in reading extremely low temperatures, and much more erratic behavior. If the thermistor is in intermittent thermal contact, it could cause small jumps like this.

Cable seems to be ok, and thermistor is not loose (it is the cylindrical e3d v6 sensor)

I'd hook up an ohm meter at the Duet end and work your way up the cable flexing it at every point to be sure. I'd do the same for the heater wiring. I just caught one this way a couple weeks ago.

I'll try asap.thx

So, I tried hook up ohm meter on thermistor cable (board side) after my extruder reach 200°C, resistance rise linearly and suddenly drop too. I did the same without the cable (thermistor side), exact same result. I think my thermistor is dead. (please, ask if you don't understand my poor english

I had the same problem last week
The problem was in the e3d connector. I replaced it and the temperature was back to normal. -
I removed the connectors and soldered, exact same problem. I will now wait untill E3D open and send a new one
-
I received the new thermistor. Everything seem's to be ok now. Thanks to everyone who tried to help me!

Hi,
How can I mark this post as "solved"? -
