Hi! I' have a problem with my jgaurora. At first start it works perfectly and the lcd was ok. Today, when I turned on my printer, I eard a long beep and in the LCD appeared 'booting' and nothing else... Someone have the reason to fix my problem?

    That is strange... I would suggest to contact JGAurora support for a replacement lcd. You could try reinstalling the firmware, but that shouldn’t happen out of the box.

    I sent an email to support and they told me that the filament sensor is poor contact and they suggest me to try to remove the b1 line. I tried that but the b1 line is very hard connected and I think that is not the problem, what you suggest to say at the support to solve the problem in the best way possible?

    That does not sound like useful advice, the sensor is either on or off, neither state should prevent the board from booting. Its fastened with hot glue, you can easily remove it with a hairdryer.

    You will then most likely see that it still does not work, and contact the support again...

    I know... I think it is a bad situation for me.. What do you think that I should say at the support? I should change the entire lcd unity?

    Probably yes, remove the sensor like they said, it takes seconds with a hairdryer (NOT heatgun!) and then tell them the result.

    I think you should remove the sensor plug. If the plug is not inserted correctly it can short circuit, causing the LCD not to boot. So yes, I recommend to try that first. But I think it is unlikely.... at least once you have done that you can be certain. Be careful as the connector is not strongly soldered down, it is only a surface mounted connector, so don't pull on it. Be sure to remove all the hot glue first, and perhaps use a flat heat to wedge and separate the connector and cable plug.

    I tried to do like support suggests me, I removed the b1 line and connect it again... it works! I fixed quickly the problem
