Candle is an open-source Window utility which works as a GRBL controller. The firmware allows you to control the 3-axis movement of cnc machines. It is a good choice for furniture manufacturers who do laser cutting or milling with tools that run on Arduino Uno.

Overview

The installation is not required. Users only need to unpack the files and launch the executable. To start working, it is necessary to connect to the CNC router via USB connection. The GUI is very simple and provides all the essential functions to G-code programs which makes it suitable for newcomers and machining experts.

This software controls the movement in X, Y and Z directions. It is possible to map the keys for continuous or gradual motion. Furthermore, users have an option to manually adjust the spindle speed and feed rate as well as define cutting work and machine coordinates.

Advantages

The program is written in highly optimized C++ code and utilizes the most innovative features of the Arduino microcontrollers, parts of which may be modeled in other specialized Windows applications like Multisim.

The software has a large user base and active online community that can help you learn the basics faster and answer common or specific operational questions.
