- python3 -m sandtable install-desktop puts a Gyre icon in the app grid and on the desktop (freedesktop .desktop entry with a "Quit Gyre" action). - The icon runs `launch`: starts the web page in the background (no terminal, own session, log in .cache/server.log) if it isn't running, then opens it. A dialog shows the reason if it can't start. - Quit link on the page (local computer only) and `quit`: stop any design, motors off, close the page. - Gyre icon (sandtable/static/gyre.svg), also the page's tab icon. - Simulator takes several lines per tick, so streaming tests aren't slowed.

Gyre - Sand Art Table
Gyre is a 12" kinetic sand table that draws patterns in sand. A steel ball rolls under glass, pulled by a magnet on a polar arm underneath. The case is about 12.5" across and 5" tall. The parts are 3D-printed for a Bambu P1S and designed in SolidCraft.
Building one? Start with BUILD.md: parts to buy, what to print, assembly in order, wiring, the first run and troubleshooting.
sand-table-v3.solidcraft: the printable design (latest). Bodies namedREF_*are bought parts, modeled for fit only.sand-table-v2.solidcraftis the previous version.print/v3/: STL files for every printed part of the v3 build. Use this set. Print the two fit tests (00,00b) first.print/README.mdhas the parts list, print notes and assembly order; the older folders are kept for reference.software/: the pattern player. Start it withpython3 -m sandtable webfor a web page with a library of designs; it drives the table from a computer over USB and erases between patterns. Seesoftware/README.md.pi/: run Gyre on a Raspberry Pi Zero 2 W inside the table, with no computer needed: builds a ready-to-flash SD card image. Seepi/README.md.pcb/: an optional custom controller board (ESP32 + 2× DRV8825, FluidNC) that fits the Uno standoffs, with PCBWay order files. Seepcb/README.md.sand-table-v2-assembly.step: the v2 assembly, for viewing in any CAD tool.design-notes.md: how it works, dimensions, parts to buy, hardware list and print settings.sand-table-v1.solidcraft,mechanism-mockups.solidcraft: earlier layout and mechanism studies.
