Missing part Multigraph
Now I have a new problem. Haven't been able to use the thing but am starting now.
There seems a bit missing between the head and the lightbox.
There is a sort of box that is fixed to the head and that will adapt the lightboxes.
See the red arrow in the attached picture.
I could of course try and make one myself but would be helped a lot if anyone has one leftover or an address where I could ask for one.
I got a better picture from the posting by ic-racer. Now I'm wondering how the lightbox is attached to the missign part.
It looks like the missing part is attached by the sliding things.
Normally the lightbox would attach to the head by these things but now seems to be unconnected. Seems strange.
