[simmonsstummer 0]

Hi, i would like to upgrade to the last firmware (cura 14.03) of my ultimaker 2..but when i attach it to the usb port of my computer it does not recognise the board.. (the ultimaker)..

i tried even with the laptop but is the same..

what i can do?

I always get unknown device.

Did you install the drivers when you installed cura?

Yes. I also use both computers to use arduino and it works flowless..

I yet upgraded months ago the second firmware so i know that should works.. but this time is behave like that..

I've seen that this could be a problem with the Arduino Board. I tried to solve it updating the driver manually to let see the computer the board... but seems that doesn't work..

Is there a way to download the ultimaker 2 driver directly??

I tried everything but nothing seems to work. I extracted the driver folder from cura but seems that the drivers inside doesn't work either..

Ok... I am lost.

Each time we upgrade Cura must be load a new firmware to the printer?

Not always. But one in a while the firmware of the ultimaker (in this case the ultimaker 2) is upgraded and you should do it. Since the release the Ultimaker had 2 firmware upgrade. This is the second... and i don't know why i can't do it! My computer (3 computers) does not recognise anymore the ultimaker 2.

So i still have the former firmware.

Did you try a different cable? There's more help on the arduino webistes but here's how to debug USB issues...

Yeah! Incredible but was the cable! I updated the ultimaker finally!

I see however that the led brightness problem is still there..
