Kevin O'Connor 0ca96e543c toolhead: Increase maximum stepper halt velocity 
Do a better job of calculating the maximum halt velocity for the
stepper motors.  The maximum cornering velocity is related to both the
maximum acceleration and the junction_deviation, so both should be in
the formula.  Tests show that "math.sqrt(8. * self.junction_deviation
* self.max_accel)" very closely fits the maximum on cartesian robots.

This fixes potential "no next step" shutdowns that could occur on
some print moves.

Welcome to the Klipper project!

This project implements a 3d-printer firmware. There are two parts to this firmware - code that runs on a micro-controller and code that runs on a host machine. The host software does the work to build a schedule of events, while the micro-controller software does the work to execute the provided schedule at the specified times.

See the features document to find out why you should use Klipper. To begin using Klipper start by installing it.

There is also developer documentation available.
