Question about the cameras

can the camera be used with a diy laser engraver has anyone done this and if so how did you set it up I have an idea but I’m still pretty new to this hobby I have a bachin D8- 4050P

Does that laser have homing switches? If not, the camera won’t likely be accurate enough. You also need to be able to mount the camera such that it is always in the exact same location relative to the work area of the laser. This usually means mounting the camera to the case of the laser, but if this Bachin machine is an open frame, that gets tricky.
