# This file is an example config file for polar style printers. One
# may copy and edit this file to configure a new polar printer.

# POLAR KINEMATICS ARE A WORK IN PROGRESS. Moves around the 0, 0
# position are known to not work properly.

# See docs/Config_Reference.md for a description of parameters.
