Installing new main board in Ultimaker 2

[stevekerikeri 1]

Hi.

I have to install a new board in one of my machines. Like a good little boy I took a photograph of where all of the wires went before starting. However, for some reason I must have disconnected EXP1 and EXP2 (connections for ribbon cable for display and control wheel) before using my brain. Is there anyone out there that knows how to tell one cable from the other. It may be that they are both low voltage input and out put but I do not want to take the risk of damaging the board so please only advise if you are 100% sure.

Thanks.

Ok just ignore that post. I looked in the how to document for the original machine. Removed the cover for the display board and the control wheel and matched up EXP1 and 2 on the display board with the EXP1 and 2 on the main board. Should work I would expect.

The best way to swap a board is usually just to have them sit side by side and swap the wires one at a time. No thinking, no mistakes!
