3V3 Plus, clicking noise in extruder

We have had our Ender 3v3 Plus since January with no major issues.

Recently, however, it started making clicking noises during prints and extruding erratically. We have taken it apart, inspected the extruder gears, and cleaned the nozzle multiple times, but nothing seems to help.

We thought the nozzle might not be getting up to temperature, so we put on a few thermocouples, and they seemed to indicate that nozzle temp may be low.

Is this a possibility? If so, what are the next steps, or are there other things we should be looking at?

Thanks!

I experienced clicking near the feeding tube and Bowden gears. I simply cleared the filament recut it and reinserted the filament. For me the clicking was because the filament was not feeding properly into the extruder.

To be sure change out the filament with a different manufacturer and see if it’s filament inconsistency.

Hello @cbrake Were you able to find a solution for it?

I had this problem before. But cleaning the gears solved the problem. But this time…

I opened and closed it several times, but it made no difference. I even changed the nozzle for it. And I came to exactly the same conclusion as you. When I push the filament into the extruder by hand, it has a hard going down, whereas before, the filament melted easily at 220 degrees.

I also checked the hotend’s appearance and it seems healthy.

I would be happy if you reached a conclusion. If you come to a conclusion, I would be happy if you could guide me.

Thanks

We replaced the nozzle, and that seems to have fixed it.

We had been printing some TPU recently, so not sure if that gummed things up to the point where normal filament would not flow through?

Or, perhaps he nozzle just needed to be changed – not sure how long they are expected to last.

Hi , thanks.

Since the hotend looked fine and was showing the correct temperature (i think,i dont have tools for getting the right temp), I thought maybe the problem was with the extruder kit.

Today the new extruder kit arrived and I replaced it, but the problem is still there — it keeps clicking, and after a few minutes nothing comes out of the nozzle anymore.

Do you think the issue could be with the thermistor?

Maybe it’s reporting the wrong temperature?

Because once, with the same filament that I usually print at 205°C, I tried printing at 260°C.

It was still clicking, but from the glossy look of the filament it was clear that the temperature was indeed higher.

Honestly, I really don’t know what else to try.

Did you ever find a solution to this mine is doing the same

The first time I replaced the new nozzle with the old one. After two prints, the nozzle got stuck again.

I print with PLA. I thought the extruder spring was loose, causing the filament to push through.

So I ordered a new motor and extruder. When I got it, I changed it and started a print. And my brain exploded.

Same problem again.

I had also bought a hotend from the same seller, but he had given me a K1C hotend. The wires were short and the sockets were different.

I had to disconnect the wires from a broken hotend and with difficulty connect them to this K1C hotend.

and Hurray! Problem solved. The moment I was opening the old hotend, I noticed that one of the wires had come loose without my hand the enameled wire connected to the ceramic heater.

And I think the hotend was transmitting the wrong temperature to the system, causing the filament to not melt properly and causing it to jam.

I hope that replacing the hotend will solve your problem.

I was really annoyed. I opened the device every day for 3 weeks. I wasted nearly 2kg of filament. Because every time I tried to print, it would print for a while and then randomly get stuck.
