Camera seems to be pretty off

[tocheeba (Sean)]

I bought a 100 degree 5mp camera off Amazon:
https://www.amazon.com/gp/product/B07C1N64PZ/ref=ppx_yo_dt_b_asin_title_o02_s00?ie=UTF8&th=1

Did the setup on my Neje Master 2S 30W MAX (810mm x 460mm) - so it’s pretty wide. Couldn’t fully get every number under 0.3 (some were like 0.45 during the calibration).

Is the camera worse than other 5mp? Do I need a wider angle camera? adjust he height of the camera? I believe the camera is sitting about 22" above the workspace.

Live preview in Windows looks like it’s pretty blurry. It’s autofocus, so not sure if the camera is just garbage. Hesitant to drop $80 on a camera from Lightburn to have the same issue.

Notice in the 2nd pic - the “shadow” is actually the printed design. So you can see how off it really is from the vector file in Lightburn.

Is the top of your material (the cutting board) at the same height as what you calibrated the camera to (or did you calibrate the camera to the height of the table top / surface it is sitting on i.e., the bottom of that material)?

If you calibrated the camera to the table top surface and the top of the material is now closer to the camera, that’s your problem.

Im confused then. Do I need to do this for every single piece I burn?

Camera alignment is accurate only with the 4 targets but not anything else you add

I have a diode laser ortur master 2 15w. I installed a camera dead all the steps successfully all the images taken were under 0.09 except for a couple that were 0.12. when I jog the laser to the 4 targets they go right in the center but when I put an object in the middle and select the top corner it jogs about an inch away from it. What can I do to fix this

Absolutely will not frame where it says it should

Hey guys, Here’s the long and the short of it Ortur LM2 20w, recently built, everything coming back fine in console, no alarms Lightburn software, licensed, latest version Lightburn camera, 5mp 160deg Love the software, really love the potential ease the camera brings. Doing trial runs and once I have the background image updated I place my edit on my printable object (small piece of plywood in this case) smack in the middle of my print bed. Click “Frame.” The dang thing frames like two inc…

Camera is always off

Yes, this is fine. During the auto-focus, what is happening here is the bed is moving away from the tip where the beam exits the lens tube for thicker stuff and closer for thinner things, but the top of your material will end up at the same location in space and should always be a certain distance from this tip. Think of it this way, the properly focused height is the top of your material. You are moving the bed to give room for the rest of the object to fit inside your laser. The top is alway…

I’m asking this for a friend, I did search and I couldn’t find anything. All the things I found I made sure it was done computer and software up to date and the camera settings switched from custom to default and vice versa everything works fine he I gets to the last step to take the pic of the 4 targets and he can’t there’s no view… I am not lazy I search and I do my best and when I can’t find then I ask

On the right when you click capture nothing happens

Thank you. This is very informative.

Is the “Camera Alignment” different for every base? Just doing the targets for various heights would be sufficient, right? I read through the posts you linked, and I could have different settings imported for various heights.

Just want to make sure its the alignment, not lens, that changes each time the height of cut changes.
