    So I've just finished wiring up the pi and next step is zaxis cabling, however I'm a little wary as there is a disclaimer about how the zaxis cables are wrong which it then explains how to fix.

    My problem is that it is showing cables with bare metal while my zaxis cables have ends on both sides. I can snip off the side that goes to the rumba and basically follow the instructions but that seems like it might be outdated information. I've attached a picture of what my motor cables look like.

    This issues was fixed some time ago, the Z axis cables are now properly twisted.
    And they have connectors now. But you can only connect one motor with a connector, you have to cut off the connector for the second one and use the screw terminals.

    I'm only part way through my build, but is that correct? My z axis cable is like a Y, with two sets of wires to the connector that connects to the rumba board.
    Will check when I get home....

    The Y-cable is probably the Pt-100(s) to rumba cable.

    Just remembered that I had taken a photo as I was putting the cable into some braid and had to dismantle the connector to fit through the braid.

    At the time this cable was connected to a motor

    I was trying to determine if I needed to cut the cable like the wiki suggested but realised the configuration they described was what this cable provided.

    That cable would appear to be connecting two motors to one connector on the board, so you don't need to cut anything surely?

    <disregard>

    EDIT: Actually taking a closer look at his cable I see it has two of each color going into it....Interesting, I do not have a cable like that in my 1.1 at all.

    No need to cut as this is the Z axis motor cable.

    Exactly, that was what I thought, good to see that they are correcting even small details like this, just a pity the documentation isn't keeping pace...

    I checked mine and I do have this revised cable fortunately. (Not that it is a major problem to cut the end off as used to be required...)
