# This file serves as documentation for config parameters of "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.
# Only parameters unique to polar printers are described here - see
# the "example.cfg" file for description of common config parameters.
# The stepper_bed section is used to describe the stepper controlling
# the bed.

# On a polar printer the step_distance is the amount each step pulse
# moves the bed in radians (for example, a 1.8 degree stepper with
# 16 micro-steps would be 2 * pi * (1.8 / 360) / 16 == 0.001963495).
# This parameter must be provided.
# The stepper_arm section is used to describe the stepper controlling
# the carriage on the arm.
