This project is a stepper motor based laser sweeping mechanism to be used with DAVID-Laserscanner. The design has been done with ViaCAD 2D/3D. CNC G-Code file generated with CamBam.
The aluminium box is RS-Components #225-192 (114x89x55 mm).
The stepper motor is used with a planetary gear box of 1:100 ratio. This gives a resolution of 0.018°.
The electronics is based on:
- Arduino Uno
- Adafruit motorshield
- Custom board for laser and light control
The different parts before machining the box:
The mechanical elements has been machined with a CNC-6040 router.
Finished project without protection cover:
Fully assembled project installed on a modified photo stand:
The full setup including webcam mount and vertical lights bar of white LED:

All CAD/CAM files including:
- ViaCAD drawings
- CamBam file
- LinuxCNC G-Code files
- 3D models in STL format
