bobmo - if you change steps parameter (B11) to 360 then changing the index parameter changes the angle 1 degree per step :)

Excellent! That helps with the stepping the linkage motion. How can I get the linkage to rotate, say 90 degrees, and return to 0.
Thanks

bobmo you can just change the index parameter or use the slider control to step through the animation.

It would be great if you could stop the linkage during its run, and if you could cycle it +/- through and angle range.
Nice work!
