We see a lot of simple pen plotter projects here, and while we all appreciate them, most of them are on the slow side. That's okay—sometimes a glacial motion is all that's needed, as long as it gets the job done. But there's nothing wrong with putting the pedal to the metal, so to speak. and that's it This Super-Fast Arduino-Based Plotter About.
As the story progresses, [IV Projects] The need for speed was felt after the creation of an earlier pen plotter project, which worked, but failed to excite. With the added goal of keeping the plotter easy to build with cheap parts, the design focuses on a "grit roller drive" for the y-axis—the one that actually moves the paper back and forth. And move it using the Dremel tool sanding drum on the lighter shaft to maximize acceleration. In fact, all the moving parts are kept as light as possible, and the results really show - the three steppers really sing when this plotter is in action.
It has some really clever details [IV Projects]' Design. We particularly like the way the pen lift mechanism works, and the surprising presence of the clothespin spring as a belt tensioner was a real treat. Given the plethora of rejected prototype parts, it took a lot of work to perfect this design. If you want to build your own, STL are available For printed parts.
