Kevin O'Connor 8f331f08d2 extruder: Determine start step offset using last commanded position 
The existing code calculates the number of steps in a move and then
spreads them out evenly throughout that move.  Change the code so that
step timing is based on where the head is commanded to be relative to
the stepper step locations.  This makes the timing more accurate - in
particular the stepper velocities will be more accurate during
cornering introduced by the lookahead code.  It also results in
slightly smoother stepper motion which results in better step
compression.

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.

Please see the documentation for more information on running and working with Klipper.
