More Camera setup issues

[Rut_Row (Ken Kyler)]

I have the 140 degree 5 megapixel Lightburn camera and am using a laptop running Windows 10. The camera is 16" about the surface where parts are laid. I have a Atomstack X7 Pro diode laser which has a 410mm X 400mm engraving area.

There is no honeycomb under the laser, just MDF and it is pretty clean.

If I focus the camera so that the dots pattern is crisp, when I go to the first step to capture the pattern, I have to refocus the camera otherwise I get the pattern not found message. If I refocus, the best scores I get are in the 50 points and up range. In some locations such as the top, it won’t find the pattern.

If I accept the default settings for the LB camera, the overlay is as much as an inch off.

What am I doing wrong?

Have you completed the camera alignment step after calibration?

[Rut_Row (Ken Kyler)]

Yes but the targets are quite fuzzy and difficult to accurately mark.

[berainlb (PY)]

Can you take screenshots of you going through the calibration process?

@Rut_Row

the best scores I get are in the 50 points and up range

I didn’t realize you could even proceed with the camera calibration at those scores.

What’s your lighting situation with the camera?

[Rut_Row (Ken Kyler)]

If you accept the default calibration for a LB camera, you go directly to alignment.

I’ll take screenshots tomorrow.

@Rut_Row

default calibration

Ah. Got you. Still curious how the alignment could be so far off.

[Rut_Row (Ken Kyler)]

Alignment is fixed.

I watched the video again and then enlarged the alignment pattern by 50%. In the process, I discovered that the camera capture didn’t show the full bed. What is odd, is the camera sees the full be in the camera control. Anyway, I ran the alignment and now all is perfect.
