Connecting Laetoly PC Driver
How to set up the local PC background driver and establish hardware serial or Wi-Fi communication with your GRBL CNC router.
Table of ContentsβΌ
Overview
Laetoly Web runs in your browser and requires the Laetoly PC Driver running locally on your computer. The Driver performs the CAM toolpath calculations and communicates directly with your GRBL-based desktop CNC controller via USB serial cable or local Wi-Fi.
Step 1: Start the Laetoly PC Driver
Launch the Laetoly Driver application on your PC. It will start a local background service on your system loopback to securely bridge your browser workspace with local CAM processing and hardware control.
Step 2: Connect CNC Controller to PC
Connect the controller through an interface supported by your Driver and machine. USB serial is the documented GRBL path; some setups may provide a network connection. For USB, confirm the virtual serial COM port is recognized without driver errors. For a network connection, confirm the configured local endpoint. Do not assume every machine exposes both options.
Step 3: Open Laetoly Web Workspace
Open Chrome and navigate to app.laetoly.com. Verify the Driver's connection status and controller state before generating toolpaths or moving the machine. A loaded webpage alone does not prove that hardware is connected or ready to run.
