As part of my laser engraver implementation that I have been working on, I

The math I'm using to determine the speed is the scan speed. So for

After looking at TinyG code for handling jerk limitation in the joint

So for an abort I think would be still following the proscribed machine

For an e-stop it will be an uncoordinated stop.
