G‑code monitor
Match any G‑code line. Fire on M600, G10, a filament swap, a pause — whatever your slicer emits.

Remotely trigger your camera from your 3D printer with SnapAzule
Acquire the Waveshare ESP32-S3 1.47inch Touch development board, subsequently flash it with our software.
SnapAzule monitors for a layer change, a coordinate threshold, a specific G‑code string,
and transmits a Bluetooth keystroke upon any occurrence. Any smartphone, tablet,
or laptop can be transformed into a hands‑free shutter.

What it does
Four ways to turn a print event
into a keystroke.
Layer change trigger
A shutter on every new layer — the classic timelapse recipe, with zero slicer plugins and zero USB tethering to the printer.
Coordinate thresholds
Fire when the head crosses a Z, X, or Y value — or after an incremental move of your choosing. Precise framing, every time.
Prusa Link + SD card
Reads G‑code passively — over Prusa Link's API or straight from the SD card. It never touches your printer's USB port.
How it works
Plug in. Pair. Print. That's it.
01
License & flash in the browser
Plug the SnapAzule into any computer, open shop.snapazule.com in Chrome or Edge, and click Flash. About 30 seconds.
02
Pair with your camera
Any BLE‑HID target works: iPhone camera, DSLR app, OBS hotkey, your laptop. Pair once — it reconnects on its own.
03
Pick a trigger
Choose a tile on the touch screen — G‑code, layer, coordinate, incremental — and press Start. SnapAzule takes it from there.
Honest about scope
SnapAzule doesn't take photos.
It sends keystrokes.
Point the keystroke at whatever app actually presses the shutter — iPhone Camera, a DSLR tether, an OBS hotkey, a macro recorder on your laptop. SnapAzule is the trigger; you pick the camera.
