Yes, it looks a bit odd, mounted at an angle like that but this appears to be how it is intended to be fitted. I believe the idea is to provide clearance for a similar power feed on the y axis although of course I don't have on here. I suppose I could have drilled and tapped new holes so that it would have been more rectilinear but there again it would have taken the operating knob lower down.
Now need to connect up the limit switches, power etc. But I had other stuff to do so it will have to wait for now...
