Robin's smt Pick and Place build

... shafts turning 2mm off centre...

Okay so I didn't quite understand the mysteries of the Reuleaux triangle but I do now.

My rounded out Reuleaux. without the pointy bits. looks okay but the centre doesn't move in any approximation of a circle

The centre of a true Reuleaux, constrained in a square, follows a sort of circle defined by the ends of 4 elipses. Mine looks like a finger painted flower

I can get true vertical/ horizontal motion if I fix the square and float everything else.

I have ordered gear wheels and lumps of brass, so I have until that arrives to simplify it.

are you still working on the project?

I have 2 problems.

I have to switch PCB supplier and I cannot decide who.

I bought a 3D printer and I have a notion that it will make the component feeders simple if only I can figure it out.

If your still working away on this as a back burner thing this may give some inspiration :)
