Due to the lookahead, small changes in the direction of the toolhead cause minor changes in toolhead velocity. These "cornering" velocity changes cause the current extruder code to trigger pressure advance and its associated pressure retract. This causes the extruder to rapidly "jerk" the filament. This code change updates the extruder to detect velocity changes due solely to cornering and avoid pressure advance. Signed-off-by: Kevin O'Connor <kevin@koconnor.net>
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.
