thanks for your suggestion i am doing a rotational delta.Quote

You can find equations for linear delta here: [github.com]
But you are probably building rotational delta (based on your previous post). Google it or write down the equations describing positions of the platform based on each each stepper motor position and solve the equations.
I'm do not know whether there is any open firmware supporting rotational delta. There is one other guy building rotational delta for pick and place machine. You may want to search history in this forum to find his threads. IIRC, he did not get any concrete links to firmware supporting rotational delta.

i am doing rotational pick and place delta. i assembled basic setup but i doesn t know how to run three stepper motors in three different directionsQuote

I suggested using nautilus gears to increase torque when needed.
I'd be interested, if these would also make the kinematics linear like I said?

Did you add it?
AFAIR, you did not respond to the other guy's question of when rotary delta support will be added to reprap firmware.
