Using fabscan without Raspberry, Arduino + Fabscanshield, Calibration?

Hello All,

since no HAT and raspberry are available at the moment I try to use an UNO with the fabscanshield. The parts I am using are UNO, Shield, two red line laser (one with stepper) and a C270 Webcam. Everything works fine. At the moment I am using the windows scan software

Simple 3d scan created by Wolfgang Schmidt. This software can control the laser stepper.

My questions:

How to calibrate the scanner (I cannot use the raspberry build in tool.

How to set the parameters (world coordinates) for the laser, turntable and camera?

Are there any experiences?

Thanks in advance for Your help.
