Rounded path

Automatic rounded corners for fast non-printing moves. Typical usage is a chain of move commands that need to be fast but can afford to not be fully accurate.

TODO: add image.

Configuration

[rounded_path]
resolution: 0.2 # the length of a circle approximation segments.
replace_g0: False # Use at your own risk

Gcodes

ROUNDED_G0 [X=<x>] [Y=<y>] [Z=<z>] [F=<f>] D=<distance>: Moves the toolhead, same as regular G0/1. The printer may omit reaching this position fully to optimize the travel to the next position. Distance is the maxiumum deflection distance from this point.

Usage

Example usage:

    ROUNDED_G0 Y=30 D=5 F=1000
    ROUNDED_G0 X=100 D=30
    ROUNDED_G0 Y=100 D=30
    ROUNDED_G0 X=200 D=30
    ROUNDED_G0 Y=200 D=30
    ROUNDED_G0 X=100 Y=100 Z=10 D=0

The rounded path chain must always end with D=0 to allow computing the final move.

Limitations

This currently only optimizes on segment by segment basis, practically rounding radius for each corner is limited by the shortest distance to previous/next point.
