Hi,
After long long time i start scanning again. but this time when i start doing planeless scanning i am getting subject error (you can see attachment). When i calibrate the camera and push the START scan button. The David Laser Scanner freezes.
My COM port in the computer is set COM1 and the Advanced setting i also checked that the Com port is COM1. My arduino is connected to the computer through COM1.

I dont know whats going on. please help.
Regards

The second problem is that the camera shows the calibration corner in the calibration window of david software. But in the scanning screen the camera just freezes. When i move the camera nothing changes on the camera image screen. the david software only freezes when i press START SCANNING button.

Hello Khalid,

It's hard to say what the cause is. Obviously DAVID cannot talk over COM1. Please make sure that no other program is using COM1 at that time, e.g. the Arduino PC Software.

Have you tried if it works with TestCOM instead of DAVID?

Does normal scanning WITHOUT COM work?

Hi Sven,
I found that the long USB cable of the CCD monochrome camera has some fault. I changed it with shorter one and it seems working Okay.
I am still unable to update my David USB from V2 to V3.
