[UltiController on 1.5.6]

Hello!

I have got a question. I can control my Ultimaker perfectly with UltiController. But the mainboard is not selfpowered. Do I need a patch with version 1.5.6?

However, for older electronics (under version 1.5.6) it is needed to patch the electronics to be 'self-powered' i.e. power the Arduino and UltiController from the 19V power adapter. Otherwise you still need to power it over USB.

thank you.
