Week 3 — Computer-controlled cutting

Cardboard Penholder

As first experiment with the lasercutter i've made a penholder with multiple layers of cardboard. I used an old graphic i've done several years ago.

Machine settings (GCC – Spirit GLS)

Lasercut file (Rhino)

Lasercut file (dxf)

2 levels of cut: inner cuts on black (first one), outer cuts on red (second one)

This is the results of the lasercutting:




Then I've glued together each layer, and this is the result:




Electronic's case for final prj

For the final project I've designed a case that will contain the electronics and will work as interface for the exposure unit; this case will have a plug and is linked to the exposure unit throug wires.

This case contains:

  1. The relays module
  2. The AC > DC power converter
  3. The timer/user interface board
  4. A power switch
  5. 3 x buttons
  6. 2 x potentiometers
  7. The seven segment displays board
  8. 1 x shuko socket for vacuum pump control (not implemented yet)
  9. The seven segment displays board

I've measured the size of these components and designed a case with a total size of 154 x 156 x 210 mm. I made a slanting top face in order to facilitate the user interface:



These are the settings I used for the cutting and engraving:

  • Poplar plywood 4mm
  • Cut Speed: 2.8%
  • Cut Power: 100%
  • -
  • Engrave Speed: 100%
  • Engrave Power: 60%

After the cutting I've glued together all the parts (except the top face), and assembled all the components, and this is the result:
