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.
