Note that this is what I found in the logfile.

On the screen nothing indicates failure, it just told me 'Calibration Finished'

Thanks for reporting. Are you able to perform a scan after calibration?

No, I cannot make a scan because it tells me the Calibration had failed

Sorry for my misunderstanding. I thought that you are able to scan and you just reported this as an issue which happens at the end of the calibration process. I will have a closer look. But i need to know how to reproduce this error. What exactly happens when you've started the scan process.

It is stange that the calibration process is finished.

The calibration values also look reasonable.  I guess you are using only one laser, right? How does your calibration pattern look like? Can you share a picture?

Yes, one laser.

Also, I use the standard calibration pattern. I did a calibartion 3 times, after each new release, all went well, except for the one of the latest fabscan-image.

I have just checked the new software dated 06-29-2020.  After doing a update and upgrade I am able to calibrate and run a scan.  The calibration sequence is different than before and the switching of the lasers and scan is much faster than before.  There is a lag in the presentation of the scan on the screen after the lasers stop.  I have not been able to complete the meshing sequence.  The notification that meshing is started appears on the screen but there is no completion. No meshed file is recorded to the respective scan folder on the micro sd card.  I can't load the point cloud files into either Meshlab or CloudCompare indicating there may be a format problem but I haven't detected it when looking at the ply file using Notepad++.

Not here... update and upgrade did not solve the problem.
