Ender-3 V3 Printers Creality Ender-3 V3 (Regular)

I have been having many issues since replacing the motherboard on my E3, V3. Support from Creality hasn’t been helpful besides them sending me new parts, and it takes forever for them to respond. So, I am sitting here without a printer until someone else can help me. I will list my issues and steps I’ve taken below.

  1. Replaced motherboard due to screen issue. It works fine. All connections have been dpuble checked and are secure.

  2. When screen starts, there is a 2511 error (temp issue). I cannot cancel it out and cannot access the settings. Cannot update firmware. Loading the firmware via USB shows up on the screen but won’t let me tap it to start it.

  3. Replaced printhead adapter plate and the hotend. This didn’t fix error code. The nozzle gets hot and starts smoking. There is a red light under one of the fan’s connections, but the fan is working fine.

So that’s where I am with it. I am very frustrated. Any help is appreciated. I

Hello Christy_Timms,

I don’t have that model, but it sounds to me like you have a faulty thermistor.

Can you check that it’s connections are ok or maybe it it cracked.

Cheers.

The thermistor comes in hotend kit. I had a new and put it on…still get the error.

Hi…Try this…Google “key 2511 sensor temerature exception” and several Reddit threads will come up regarding this problem on the K1. Most refer to the thermistor cable or sensor. Worth a look…Mike

Hello, Today I have replaced the main motherboard following the official video in Youtube. Once I powered on the printer, I have the same issue as you, same error, chinese screen and smoke in the hotend. Did you solve this error? I’m so tired with this printer, I have a lot of fails in the last 3 months, lots of prints directly to the garbage… And now…this error…

Thanks!
