Rotary axis question (rotational)

What is the benefit of declaring an axis a rotational axis?

Is there no positional limit? Are there other differences?

Thanks!

Do not declare something as a rotary axis unless it is one. Try googling linear vs rotary axis.

One is designed to move in a straight line, the other rotates about a fixed point.

The main difference is that if any linear axis is moving, then rotary axes do not take part in the feed rate calculation.

@dc42 Thanks....but what does that mean, exactly? Does it mean a rotary axis will not limit the speed, or it follows the rate of the other axes to end at the same time, regardless of which axis would have been the limiting axis? Or does it mean it will go its own speed?

I have a rotary axis on a project that started with an older firmware. I'm trying to decide if it's worth "converting" it to a rotary axis in the code. Will my code be affected?

an

DC, any chance you can help with that? Thank you.

It means the rotary axis is independent from the linear axis.

correct.
