Do you know the Star Wheel drive like that one ?

I need information how to draw it and size it proceduraly.

Re: Star wheel drive. Information needed.
Geneva Drive and Star Wheel drive is a little different.
Take a look at my current solution: This system will turn the cross 180 deg in one cycle.
It is what I need but the problem is how close to the center of the cross the pin will be (red point on a picture) I will need a very high torque for this point since there will be a load on the shaft attached to the cross.
Now it looks like the star wheel have this point much further from the center so It will trade acceleration <=> torque.
If there is a better solution than those above to solve my problem, please share.

Re: Star wheel drive. Information needed.
In the video, the "arms" begin at a way more distant point from the axe as in your screenshot. If you're not constrained by the distance between the 2 axes, I would suggest to do that too.
Find your user.cfg and system.cfg files : Macro_findConfigFiles

Re: Star wheel drive. Information needed.
As I know you cannot move Geneva wheel and cross apart as you want.
It is the math that dictates the distance and length of pin slots.
If you got an example I will gladly see it.
But every example of 4 slots cross I saw on the internet got the problem I have mentioned (pin slot to close to the center)
