Programming specific shape movements

I need to program an effect where 2 moving lights make mirrored circles that run repeatedly. However, when I use the effect that has a pre built circle, it doesn't actually look like a circle on the stage. Also, they tend to not start and end together. Can anyone give me guidance on haw to make something like this?

    first of all: depending on orientation of your chosen centre point of the circle, this might me physically impossible for the moving lights themselves (unless you're using one of the fancy new movers with infinite pan and tilt). basically if you have a circle that goes around the home position of your moving light, no matter if it keeps the same distance around home position or if it's sometimes closer or further away, you will not be able to achieve it. your circle needs to stay one side of the home position rather than going around it.
    that's not a limitation of Eos, it's a physical limitation of the movers.

    as long as your circle is in a relative position that allows a circle, Effect 901 will actually do a circle.

     

    let's start with this and take it from here, and we'll find the correct settings you need to get the opposite directions. but we need to make sure first, that you can get a circle.

    In order to create a perfect circle, the lights need to be shining on a surface that is completely flat and 90 degrees to the center of the circle. E.G. a light is hung pointing straight down on a flat floor and the center point of the circle is the light's home position. The more you deviate from this angle, the more elliptical the shape will be.

    I know this is an old thread, but now with Augment3d, it would be handy to be able to program a circle in the x/y coordinates. I've tried this, but it doesn't move. The numbers in the live table on the x/y focus move, but the light doesn't move.

    Did you make sure the this channel was in XYZ Format, rather than Pan/Tilt format?
