Hey there guys,

I'm doing a microscope animation but the transformation constraint I've got isn't working. here's the file using Blender 2.64.9 (r52542M) on a Mac ...

Here's my file where you rotate the arrow empty to lift up another empty that is parented to a object (the microscope tray).

Problem is the tray is lifting the right distance but only when you rotate 180 degrees when i need it to rotate 360 degrees for that distance. When I put 360 for the rotation it jumps back to it's first position at 180 degrees.

Hopefully that makes sense.

Can anyone help?
