About this app

Turn your phone into a complete, wireless pendant for your desktop CNC router, diode laser, or CO2 laser engraver. Cut the laptop cord, connect via USB OTG or Bluetooth, and jog, probe, simulate, and stream G-code directly from a modern mobile interface.

Optimized for top desktop machines like Genmitsu 3018 Pro, xTool (D1 Pro/P2/F1), Ortur Laser Master, Sculpfun, Atomstack, Shapeoko, X-Carve, Onefinity, Makera Carvera, and custom builds.

✅ UNIVERSAL COMPATIBILITY (CNC & LASER)
• GRBL 0.9 / 1.1 (Arduino, CNC shields, diode/CO2 lasers)
• FluidNC (ESP32, Wi-Fi & Bluetooth)
• grblHAL (32-bit GRBL)
• Smoothieware, Marlin 2.0+, RepRapFirmware

📲 CONNECT YOUR WAY
• USB OTG (Plug & Play)
• Bluetooth (HC-05/06, ESP32)

✍️ POCKET CAD/CAM & PATH GENERATOR
Skip the computer for quick jobs! Use the built-in sketch tool to draw custom toolpaths, surfacing operations, and cuts for small projects. Generate and stream G-code directly from your phone in seconds.

🎮 PRECISION JOG & FULL LASER CONTROL
• Large jog pad with adjustable step/feed rates.
• Dedicated spindle, laser power, and coolant toggles.
• 1-tap set-zero (X/Y/Z) and go-to-zero.

▶️ UNSTOPPABLE G-CODE STREAMING
Our wake-lock background engine keeps G-code flowing to your CNC router or laser machine even if your screen turns off or a call comes in. Never ruin a workpiece. Track live progress effortlessly.

🧊 3D SIMULATOR & 2D PREVIEW
Visualize routing paths and laser burns before you start. Catch errors before they hit your wood or acrylic.

🎯 PROBING & 3D SCANNING
Z-probe, corner/center finding. Turn your probe into a 3D scanner to digitize surfaces into STLs.

🛠️ PRO WORKSHOP TOOLS
• Built-in G-code editor & live raw terminal.
• Visual Grbl settings ($$) editor.
• On-the-fly feed, spindle, and laser overrides.
• Wi-Fi file sharing from PC to app.

Ditch the laptop. Take precise control of your CNC and laser workshop today!
