This is the image I get whenever i switch the camera to 5 mp. Every other camera setting works fine until I go to high resolution. I cannot calibrate the two lasers if its not in 5 mp mode. Any ideas on why I can not use 5 mp setting?

if lasers where aligned and an item like calibration item was in position at center turntable you would see laser lines in an upside down V to center become 1 vertical like 3" tall to that center camera cross hairs horizontal line then broken lines beyond turntable. so best these images can show is camera is centered on turntable surface instead of 3" above and camera settings are manual and typical dark image like mine did at 1st.

these are just some of the problems encountered with the scanner as is now. lots more

if lasers are indeed aligned in all directions correctly and you looked at camera view (even if dark like these pics) then the laser lines would not be shown as an X centered with camera cross hairs because the cross hairs are just over 3" above center of turntable where lasers lines cross paths which is much lower than center of camera view also there would be another pair of yellow/green plus signs lower.

when I 1st tried setting lighting/exposure the best manual setting I could get with an object in color sitting on turntable was a very dark dim shadow and the same bright lasers at normal room lighting, or completely dark like these pics with room dark, or with bright sunny sky light from window it washed out laser light and had over exposed color view of object etc. I had to make an enclosure with black poster board around scanner leaving top open for room light and set to an auto setting for camera to get perfect view. plus my whole scanner was spray painted flat black to prevent any stray reflections and my poster board also was tall enough to keep laser light from getting out and harming eyes etc. I used my SD2 deluxe case turned upside down and sat scanner in it with turntable hanging out back side and part of scanner out front end then split a full sheet of black poster board in 2 lengthwise and bowed each half just enough to slide ends in both side from each end in a U meeting in middle and propped rear half up just enough to retain laser lines. worked like a professional photo booth with open top.

Attaboy... That's the way to keep it on topic.

also if camera settings and ambient lighting are not set correct or auto with low light then you will only see laser light and the builtin crosshairs which is how mine also was for a long time due to never able to find a manual setting that worked.

Please read the OP's post, and please take a look at the photo he posted.
Then please take a look at the answer link provided, and you will see that the OP's issue has NOTHING TO DO WITH THE LASERS, OR THEIR ALIGNMENT!
It has to do with the camera not initializing, which is most likely due to not enough GPU memory.

I did look at all you list and neither of these topics had that issue the photos posted in both ARE showing what camera sees if you have black background as myself and others. the crosshairs are as the designer posted in the prev topic said "generated by the camera software on latest issues'

the bright Red X as both topics say and show is the lasers which are lined up with center crosshairs camera generates so they have not been aligned correct at this point and there is no calibration item or anything else on turntable. when you click test you wont see the bright red X and the only way that X can be shown in a photo is if camera IS initializing and working correctly. I think the person in prev topic simply said you guys helped and its fixed is because he figured out his mistake and didnt want to say so. but what I stated still needs adressed or these type topics will keep coming back to haunt us.

also most people new to this tech dont understand they need to either print the calibration item (which often has errors like splits or warped making it useless) or use a strait object that can sit flat on turntable and have a flat 90 degree surface for lasers to shine onto and have the top of the object at proper camera center aim lined up with center of lasers in their mounts. and also a center vertical line to line lasers up with at center of turntable. this info is a bit hard to follow in instructions also.

I use a plastic music box shaped like a large match box with a thin strip of sand cloth on one side (striker like for matches) I use as the center line and the box is just the right height for camera aim, this works perfect for calibration. since my printed item is warped on the side used for that and wont work, also has a split making top uneven. I did not print it, someone else did)

red laser beams are focused and/or patterned using Ruby rods cut, arranged and aimed when set in place and cant be changed electronically other than off/on pulse rates as used in fiber optic data transfer.

lol I remember buying plans from a oddity catalog back in the 1960s for $5 that had drawings and instructions in black and white how to build a small Ruby laser gun basically like todays laser pointers which can be bought ready to use for less now. LMAO

yeah that topic link barely touched on this issue. what the OP is saying and I too had this issue since none of the Atlas instructions tell you that you must twist the lasers so that the line generated by both is vertical.

all instructions just tell you to insert lasers, tighten clamps etc then calibrate. but no place does it say to twist laser to make line vertical as there is no software/calibration that can fix that.

I have seen once where somebody said something about that line can be upside down causing some error, but I dont understand that at all. its not like pos/neg on speaker wires or something its simply a focused beam of light and dont matter which end of line is up. as long as both lasers line are strait up and down B4 moving aim left or right to center on turntable.

Camera Tab Red X

2016-03-10T23:55:59Z

We carefully assembled the atlas 3d per assembly video. However, when we start up FREELSS software, the camera tab just shows a black screen with red x. The red LED camera light is on. The lasers are on.

We also tried a brand new camera, but that did not fix it.

Any advice for troubleshooting?
