I found an ebay seller that is selling the same camera that Lightburn is selling for less than 1/2 the price. Definitly worth a look if your interested in using your laser engraver and laser cutter with a camera (which I highly recommend). Lightburn makes in very easy to install and calibrate. The camera is simple to install. Purchase the camera, purchase the camera mount from my etsy shop, install on your laser with 2 screws or hot glue, and then plug the camera into your computers usb slot. Lightburn will walk you through the calibration. The whole process should take around 30 minutes. Now you can laser exact spots and never have to set up or waste material again!
Below is a video I've made showing how to install and calibrate the Lightburn Camera on a Laser cutter and laser engraver.
