Gerbers and source files for the Polarshield

Open source hanging polar drawbot and CoreXY desktop drawbot.

Simple printer

Firmware for PolargraphSD based on Arduino MEGA 2560, current until 2018.

Schematics, board and gerbers for Polarshield v3

Polar wall plotter calculation and analysis tools.

Families of polar curves

Graphing Calculator

Improved version of the polar grbl from ilaro-org in order to smooth the movement of the servo motor. This improved version of the polar grbl is intended to work and has been tested only on polar machines controlled by Arduino Uno (ATmega 328p)

PolarGraph Network Hack: PolarshieldSD v3.0e modified to use WiFi for communication between controller and server. ESP32, stepper motors, and the Travelling Salesman Problem

A Python program that displays polar graphs

CNC firmware for many different control boards and kinematic systems. Originally the brain of the Makelangelo art robot.

Polargrapا machine for image drawing

A handy utility for generating different types of polar plots, primarily tailored to directivity plots

(WIP) A variant of Grbl (v1.1g) for Arduino Mega with support for hanging wall plotters

Marlin adapted for polargraph vertical plotting robots. Defaults to dimensions for Makelangelo 5

Software for plotters - especially the wall-hanging polargraph also called Makelangelo.
