Sand field diameter (or dimensions for rectangular tables) determines the resolvable detail level and affects SVG export sizing. See the reference target device analysis for how these translate to pipeline resolution.
XYLA tables have a rectangular sand field with rounded ends (stadium shape). The .thr format does not work correctly for XYLA – SVG or G-code is required. See formats.

Dimensions sourced from Sisyphus admin (Matt Klundt) on the Sisyphus forum.
Physical diameters are from the project README. The Dune Weaver software does not store physical dimensions – it uses a normalized coordinate system (rho 0.0–1.0) with the mapping to physical radius handled entirely by motor gearing and steps_per_mm in the FluidNC firmware.
Sisyphus Industries is the original commercial kinetic sand table, inspired by Bruce Shapiro’s art installations. Their .thr format has become the de facto standard for polar sand tables.
Oasis (Grounded) targets a more affordable price point. The Oasis Mini ($129) is the most accessible commercial sand table. Side Table and Coffee Table are in pre-order, shipping March 2026 (as of Feb 2026).
Sandsara has two firmware generations with different format support. The original open-source firmware (GitHub) reads .thr files directly from the SD card. The newer Mini Pro firmware uses a proprietary binary .bin format transferred over BLE only. The official app includes a pattern creator described as “powered by Sandify.” See formats for details on the binary format.
CrunchLabs Sand Garden was a Mark Rober educational product. Though apparently discontinued, Image2Sand’s “Default” output format was built specifically for it. The large CrunchLabs/Mark Rober YouTube audience means there may be many Sand Gardens in the wild.
Dune Weaver is the most active open-source sand table project (282 GitHub stars, v4.0.5 as of Feb 2026). It uses a Raspberry Pi + DLC32/ESP32 running FluidNC, with a modern React web UI. All three models use IKEA furniture as the enclosure. Accepts .thr files only – no SVG support.
V1 Engineering ZenXY is a Cartesian (CoreXY) design, part of the broader V1 Engineering CNC ecosystem (MPCNC, LowRider). Uses Sandify for pattern generation.
rdudhagra Sand-Table is a well-documented DIY Cartesian build (~$750) that is natively compatible with .thr files despite being a CoreXY design.
