Camera
Show
Camera Show displays the view visible to a USB web-cam, mounted alongside the spindle, looking down on the workpiece. The large cross-hair marker in the center of the view is used for precise ‘targeting’ of points on the stock, for measurement or capture purposes.
Available USB web-cams are listed in a drop-down in the center of the panel. Depending on attached hardware, options to use camera filters may also be shown. PlanetCNC TNG software provides adjustment, so the basic web-cam option is selected. Basic web-cam hardware is suitable. It is much less costly to replace in event of failure or damage.
Camera hardware mounted close to spindle experiences much vibration. Robust construction and the ability to mount hardware securely are the most important considerations when choosing web-cam tool sensors. Camera and camera cable might also be source of electrical interference.
