Key capabilities

Verify and zero visually.

Jog and zero visually

Double-click to jog to any position or drag & drop the visualization to easily set zero.

With "snap-to-toolpath" enabled, you can double-click anywhere on the toolpath visualization to move the machine to that exact XY coordinate.
Verify cut at a glance

Overlay the programmed path on the live camera view so you can catch clamps, fixtures, and stock rotation issues before pressing start.

With the camera aligned to machine coordinates, you simply look at the overlay to confirm the cut will stay on the material as you expect.
Hide the machine when it blocks the view

Enable hide-machine mode to dim the machine when hardware is in the way, so you can still see the stock.

No need to manually move the machine out of the way in many cases - you can still see old pixels for areas currently occluded.

Cutting a small board while the overlay highlights the programmed path and the stock stays visible behind the machine.

Camera, ArUco markers, and optionally a FluidNC controller.

Camera: Mounted so it has a clear view of the CNC table. Options include:
- Old smartphone - Ceiling mount 3D print model
- IP camera - Requires go2rtc gateway to expose stream in a compatible way. Go2rtc can run on a Raspberry Pi Zero or any local machine. Reolink E1 Zoom 3D print model
Camera calibration is integrated as part of the setup process.
Markers: Printed ArUco markers keep pose estimation locked in, even if the camera or wasteboard moves.
(Optional) CNC controller: FluidNC WebUI v3 integration for click-to-jog and sending programs directly. Does not work offline ATM, so FluidNC needs to run in STA mode.
