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.
Replaced motherboard due to screen issue. It works fine. All connections have been dpuble checked and are secure.
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.
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
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…
I know this is a year old and may not be of much use to you, but I have the same error on my E3 V3 and it may help anyone who has had a recent issue with this. Y axis homing was failing so they sent me a new motherboard (there is no physical limit switch on the Y-axis). Replaced the board and got the 2511 error and nasty smelling smoke from the hot end.
I tried to insist on a replacement as problem started at 3 months - but I hadn’t realized how terribly short the return warranty is. Anyway they suggested a thermistor replacement next.
Decided to check the thermistor resistance and it was 120kohm at 20’C so not open circuit.
Then checked all the connectors on the motherboard - all OK - restarted and got the 2511 error again.
So, I decided to put the “old” motherboard back in - and hey presto- no 2511 error. I have requested a “new new” motherboard (and a new hot end in case it’s damaged) to see if that solves my problems.
