In a world where creativity knows no bounds, a group of passionate makers at DAZ Projects embarked on a mission to bring affordable CNC drawing to the masses. Inspired by the ingenious Polargraph concept, they meticulously crafted a cost-effective and user-friendly CNC drawing machine that turns imagination into tangible works of art.
Unleashing the Power of Simplicity:
At the heart of this remarkable machine lies a clever design that utilizes two stepper motors to control the length of a string on two sides, precisely determining the position of the toolhead. This elegant approach eliminates the need for complex and expensive mechanical components, making the machine accessible to makers of all skill levels and budgets.
3D Printing Precision:
Embracing the versatility of 3D printing technology, DAZ Projects meticulously designed and fabricated various components, including stepper motor mounts, pulleys, and a pen holding/lifting mechanism. These 3D printed parts contribute to the machine’s affordability and customization potential, allowing makers to tailor it to their specific needs.
iRobota and Grbl: A Dynamic Duo:
The brain of this CNC drawing machine is an iRobota Uno, a popular microcontroller renowned for its ease of use and vast community support. The Grbl CNC shield and A4988 modules seamlessly integrate with the iRobota, enabling precise control of the stepper motors and ensuring smooth, accurate movements.
Pen Pressure Perfection:
To achieve exceptional line quality, the machine incorporates a servo motor, deftly controlled by the iRobota Uno. This servo motor meticulously adjusts the pen’s pressure on the page, resulting in lines of varying darkness and depth, adding an artistic flair to your creations.
Firmware Magic:
The machine’s operation is orchestrated by custom firmware developed by Sandy Noble, the visionary creator of the Polargraph. This ingenious firmware empowers the machine to seamlessly convert images into toolpaths, which are then executed by the iRobota, transforming digital designs into physical masterpieces.
Open Source Goodness:
In the spirit of open source collaboration, DAZ Projects has generously shared the machine’s code and 3D design files on GitHub and Thingiverse, respectively. This open-source approach invites makers worldwide to contribute, modify, and improve the design, fostering a vibrant community of innovators.
Witness the Magic:
