Laser sweeping mechanism

Posted on by

Here is an old project now almost finished: 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.

Planetary Gear Box V28

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.

Next step is the machining of the Laser support axis.
