#SISYPHUS MACHINE DRIVER#
However, in the end you will want to use a Motor Driver To this design is that the motors are mounted in such a way that they aren’t required to move, resulting in the abilityīehind every design that I’ve come across is the the use of high-precision Stepper Motors.įor now, here are some great introductory articles on Stepper Motors. Here’s a great Instructables project for creating a DIY linear actuator.Īnother XY plotter configuration uses the Core XY layout. I made this choice because I came to the build with no experience and wanted Within the XY plotter family there are some options for drive configurations. Mine with only a few cuts through extruded aluminum beams. My build uses an XY Plotter, primarily because I have very limited machining resources. The Sandsara table by Ed Cano uses a SCARA mechanism. The Sisyphus table by Bruce Shapiro uses a polar plotting mechanism which they call the Sisbot. In my research I’ve come across 3 main different types of plotting mechanisms: XY/Rectangular/Cartesian, Radial/Polar, SCARA. Additionally, I prefer to use supported and well-documentedĬomponents over inexpensive, undocumented ones, so I have prioritized those over cheapers options. To use as many pre-fabricated components as possible. With limited access to machining tools, it’s important for my project Others made from balsa wood and hot glue. I’ve seen tables made from 3D printed parts and Everyone has access to different budgets, It’s that there is no single way to build one. Since resuming my work I have found many other sand table builds, and if there’s one thing that’s certain, Share my research and development process along the way.Link static and/or dynamic patterns to represent dynamic data sources (part of the original vision for Gravitable).Create a public web site that allows visitors to send patterns to the table to be drawn.
#SISYPHUS MACHINE CODE#
In 2016 Bruce ran a very successful KickstarterĬampaign to turn his Sisyphus table into a consumer-oriented furniture piece. Many advances were made in electronics, noteablyĪs well as knowledge-sharing platforms like YouTube.
I kept my incomplete work, always hoping to have the opportunity to resume the project. My thesis, and I never completed my table. My attention turned to finishing the written portion of I wasn’t able to fabricate or source one at that time. I started building my project from pieces of a large-format printer, without any knowledge ofįew images I had seen of Sisyphus tables, I started building a radial plotter design.
