Ant No
 

What I'm wondering is if the spi can allow microstep switching on the fly? There's someone in another forum relating to automating metal working machines that's interested in that.

I thought you'd know the answer.

Thanks Howard.

Is that the way On-Step implements control or a limitation of the driver itself?

For OnStep version 4:

Only the micro-step mode is switched on the fly.  The advantage being that you don't need to switch "just one or two levels".  For example, switch from 128x (tracking) to 4x for (slews.)
Now as before everything else (decay mode, current level, etc.) is switched before/after the slew.

This matters most for the Mega2560.
