- For
- GRBL laser owners and LightBurn users
- Worth noticing
- The Bridge is described as running whole jobs locally, so a sleeping laptop or dropped connection does not stop a burn.
Field notes
The app supports layer-level speed and power settings, and its burn preview is described as showing both the job and an estimated duration. The site presents two setups: connect Kerf directly to a computer plugged into the laser, or place the Bridge near the laser and send jobs over the network. Desktop builds are labeled alpha and the iPad build beta.
