Camera selection

need help to know what lens for camera will be mounted 15 to 16 inches above bed bed size 200 by 300 and hope to sometime increase to 300 by 600 on k40

If you are using Lightburn software then check out this link:-https://lightburnsoftware.github.io/NewDocs/UsingACamera.html#choosing-a-camera
The 5mp - 160 or 5mp - 140 camera should work fine. Most K40’s have feeble, flexible doors you will need to add another support stay opposite to the original. Depending on your machine you will probably have to mount the camera externally on the outer lip of the door.
