ER207 - There was a serial communication within the electronics

Posted · ER207 - There was a serial communication within the electronics

since I haven't worked on the UM2+connect I'm not sure but you can always browse to www.ultimaker.com/ER207 which will tell you a tiny bit more...
the important part in this one is probably: "Unfortunately this error most likely means there is a faulty component in the board. If you are encountering this error, please raise a support ticket."

    The help text on the website needs some improvement.
    First of all, there is most likely no hardware problem. We have two cpu boards communicating with each other, and when there is no communication for 30 minutes, then there follows a safety shut down.


    What I assume happened here is, you powered up the machine and then you were going to update the firmware. This took some time and the 30 minutes time limit was exceeded.
    Am I right? If not, can you then explain what you did when the error message appeared?


    For now, reboot the printer and install the latest firmware and you should be good to go.
