    I am on the first step of mounting the Power Supply Unit (PSU) and need a little advice. The Wiki says to use M3 screws from the underside of the base. However, the holes in the PSU that line up with the holes in the base are for an M4 screw.

    Has anyone else had this problem? Am I missing something?

    Thank you in advance for the help.

    I honestly can't remember them being different than the instructions.

    Are there more than one set of threaded holes? Possibly of different sizes?

    Once in the base it is never to be seen again.

    PS Read the posts on the Pi and USB as if you have not got to this stage yet you may want to change the way USB is connected between Pi and Rumba............ i.e. before you close the base forever.

    Mine was almost certainly M3, if I'd have had to use M4 then I would have been stuck as there are no M4 spacers in the kit, so I would have remembered that.

    I have solved the problem. Thank you for your help and feedback.

    The issue is that there are more than one set of mounting holes in the base plate. One set of 4 circles line up with the M4 screws and another set of holes and slots line up with the M3 screws.

    And the picture is somewhat ambiguous if I recall...
