SoliForum - 3D Printing Community — New extruder and nozzle, but stuck at 10 degrees C. No power to nozzle

FOUND OUT A FIX

I was troubleshooting with a multimeter and had the following "clues"

Thermistor was correct resistance
Bypassing thermistor with 10k resistor did not change temperature
No voltage to thermistor

After a firmware update, I narrowed the problem down to the hardware. Since the thermistor seemed as if it wasn't hooked up at all, I checked the motherboard by opening the back panel.

Sure enough, there it was. A loose connector. (I was originally looking for a fuse). I pushed it in and the printer loaded normally. I'm so happy

...And I'm 16. Lol.

Thanks, Ash. My latest update is that XYZ finally got back to me and is cooperating. Amazing what happens when you file a BBB claim and utilize social media. Here's what I've discovered:
1. I am supposed to use the extra wires that came with the new nozzle. Now before issuing a "DUH!" towards me, wait for point #3.
2. She asked if I followed the directions in installing the new nozzle which would tell me to use the new wires. I stated negative as there were no instructions with the parts. They forgot to include them.
3. Wait for it.............the two wires they sent me do NOT have the correct connectors to attach to the motherboard. The connectors work correctly at the nozzle, but not at the MB. I sent them pictures showing old wire, new wire and motherboard connection point. I have been asked to wait three business days while they figure it out as she says I have too new of aprinter and the wires are made for the older version.

If your old wires to the extruder are not damaged you really don't have to change it. If the thermistor is your problem you can just swap them. And if it is your wiring you can use just the plugs from the old wiring and swap out the wires that are bad.

So solder the new wire to the old wire plug. Just curious what was wrong with your old extruder?

My DaVinci 1.0A was stuck at 10c and after a while came up with an 0011 error.

After searching for possible causes I came across a site that showed a video of exactly what was causing my problem, a loose connector to the head.

Maybe this is causing your issue, the video is here :- https://www.youtube.com/watch?v=xyn6TOsemqI

I hope it is the same cause of your lack of nozzle heating.

Facepalm.... Guys 10c means that the thermistor isn't working.... There is no such thing as a 0c temperature in xyz
So to answer the OPs question, the thermistor is broken.

I know that and you know that. As you can see by all my post I am pointing to the thermistor or its wiring. OP just seems a little bummed that he still has the same issue.

Oh I forgot to add. The thermistor wire travels out the pcb board back to the motherboard. It is possible your wiring has a loose connection and you can only find this out by shaking the wire to see if temp changes. Sounds like you had this problem with your last extruder. So there is a good chance it's wiring that needs a repair.

Carl, nothing changes. I should add that everything I have tried is while trying to load or unload filament. No error messages. Screen still showed 10 degrees C.

So I would assume your current room temp is not 10c or 50f?

If you unplug it and there is no change then the machine is not showing the thermistor as being present and 10c is just the default open temp reading.
Do you have a multimeter or can you buy one frome home depot or lowes for 30 bucks that will measure resistance?

If you unplug the thermistor do you get any kind of machine state or temperature change?

Confirmed three red lights on motherboard. Wiggling the thermistor wires did not change temperature. Tried entering bootlog and resetting to factory default settings. All wiring connectors firmly seated Nothing has worked.

Carl, how do I fix the issue with the firmware as you described above?

The firmware is not the problem. It is working as it should. Again the problem is with the thermistor, it's wires, or connection.

Thank you for the advice. I did see three red lights last night when I peaked back there. I will try the thermostat wire wiggle tonight after work.

This is not a firmware problem if you are running xyz software. You either have a bad thermistor or your motherboard has a short. Why dont you check the connection of your thermistor to the small pcb board in the extruder. It is on the side of the extruder. There are two small plugs, one is the fan and the other is the thermistor plug. I would make sure they are secure first. If they are secure and you still are reading 10C try wiggling the thermistor wire to see if the temp changes at all. if the temp changes happen when you wiggle the thermistor wire then you have a bad wire that needs soldering. If you still have 10C after all these suggestions then you need to check your motherboard. Open the back of the case to access your motherboard. Power the printer up, dont touch the motherboard. you should have 3 led/lights on in the motherboard. if you don't see all 3 lights then you have a short in your motherboard.
