Sand Table
An open-source platform for building DIY sand tables (like the Sisyphus or ZenXY)
Designed by Ravi Dudhagra (@rdudhagra)
Inspired by Bruce Shapiro's Sisyphus Tables, I created my own DIY sand table that uses a CoreXY system to create a square-shaped canvas, yet is still fully compatible with Sisyphus Table .thr files.
The table is built out of half-inch plywood and some 1x8 pine boards, glued/nailed together, and painted glossy black. The CoreXY system is built out of OpenBuilds V-Slot rail and 3D-printed parts. Use of Trinamic's TMC2209 stepper drivers means quiet movement and sensor-less homing, further simplifying the electronics under the hood. The table can be controlled directly from your smartphone thanks to a webserver that runs on an onboard Raspberry Pi. This table makes an extremely fun and rewarding project that will last a lifetime, and should cost less than $750.
See the Build Guide folder for instructions on my specific build, or visit the other folders for direct access to the software. Check out the discussions tab for other helpful info/troubleshooting advice.
