Hi, I did draw up a Geneva drive, with all components. I sized it right and have assembled it such that the two wheels can rotate about their axes, but I cannot constrain them such that they are rigid with respect to each other (or, in other words, to make the cam turn the Maltese cross wheel). How would you go about this? If there is a video you made showing how you constrained them, please do point me to it. Many thanks in advance! :-)
