- python3 -m sandtable web: local web page to play designs from a library of 27 built-in patterns, upload .thr or .svg, pause/skip/stop, jog and calibrate. Reconnects by itself when the USB cable comes back. - Plays .thr files and built-in generators with an erase spiral between them, constant ball speed, host-side homing on stock GRBL 1.1 (Uno + CNC shield), FluidNC for the ESP32 board. - Home switch guard: patterns never press the switch, so a press means lost steps and stops the machine at once with an alert. - lineart.py turns SVG line drawings into one continuous path. - Tests against a GRBL simulator.
