Am i the only one having this issue ?
Strange …


I got this issue to… and yesterday, I don’t have anymore Camera Capture button on Snapmaker software. Any helps or inputs will be appreciate!


Are you running on windows 7 or windows 10 ?

I am having similar issues with my Camera Aid. Except I just get blocks that are a different colors instead of pictures. Not sure what is causing this or how to fix it. Everything seems up to date.

I am running Windows 10. This is happening on both of my computers.

I have similar problem. I close the app and increase the room light.

Your camera calibration is incorrect, you might need to redo the camera calibration.

My calibration is just perfectly on lines of the square :

But i still having these bloody black lines !!!
The support don’t know what happen, the original pictures looks right but then, after being stitched, there is lines on the left side of each picture…
I’m still waiting an answer from the support.
We’ll see.

Hi all
Please find below the answer from the support :
Our software engineer have tested the latest version of the Snapmaker Luban today.

It will solve the black line issue when it is released later.

Sorry for the inconvenience.

We will post the latest information about the software and firmware in the official forum:

Have a good day

Let’s wait and see…
