Connection issues.

[motogpfan82 0]

When I have my original Ultimaker plugged into my computer via USB cable and with the power supply off my Ulticontroller says Ultimaker ready along with other machine info, I can upload the firmware, and also run the first part of the bed level wizard where connection is established. The moment I turn on the power supply my Ultimaker will lose connection to Cura and my Ulticontroller display goes from displaying my Ultimaker information to just white blocks. If I turn the power supply back off the Ultimaker will not reestablish any kind of connection such as the ability to upload firmware or the first part of the level wizard were connection is established until the computer is restarted. After I restart if I keep the power supply off it will establish connection to Cura in terms of the ability to upload firmware or run the first part of the bed level wizard, and my Ulticontroller will say ready and display the machine info.

 

I' am also unable to print directly from the Ulticontroller, and it does seem like my computer recognizes the Ultimakers connection because it does show up in my COM8 as Arduino Mega. And yes the Ultimaker behaves the same on different PC's. Any help with this would be great I would really like to solve this issue. Thanks.

It's normal that the computer thinks an UMO is an arduino mega.

What you describe sounds like some sort of short circuit in the power of the upper board (eg; the shield that sits on top of the arduino mega). It's a hardware failure, so you'd have to contact support for that.
