After a while the printer rebooted and came back to life (many thanks).

What worked was to download the Arduino source sketch from your link (I actually removed the last “Extended” from that path and found what I’m presuming is the source for the “standard” (not extended) machine, I hope that was an OK version to use) into Arduino IDE v1.8.7, selected the 2560 board type and then compile/verify in the IDE followed by upload. Avedude (actually I used AvrDudess in “Wiring” interface mode) seemed to try to program the 2560 but kept timing out. Now have a machine which appears to be alive again at least. If not, you can download the source of the UM2Extended+ here and open that in Arduino and flash it to the Arduino Mega 2560 that is hidden in the printer:Īhoeben, thanks very much indeed for the help. hex file straight from the Arduino IDE, but if you have ever used avrdude, you should be able to figure it out. hex file is included in the Cura download (C:\Program Files\Ultimaker Cura 3.4\resources\firmware\MarlinUltimaker2extended-plus.hex).

Fortunately there are other tools that are less stubborn (and - truth be told - yours is a somewhat exceptional situation normally firmware updates are fairly safe). It is sort of a chicken/egg situation you have to fix the firmware in order to make it behave like a printer again, but you cannot fix the firmware because it is not behaving like a printer.

Your printer as apparently not responding as a printer would, so Cura thinks it is just another type of serial device instead of a printer.
