Group assignment

I worked with Ambroise De Vries to characterize the laser cutter at at Digiscope Fab Lab.

Digiscope Epilog Fusion M2 laser cutter



Overview


Zoom on control panel

How to set up



Start the ventilation system


Start the compressor


Start the Epilog Fusion M2


Wait for the machine to “home”


Put the stock to cut on the table of the machine, align it to the top left corner of the table guides.







Select the “leg” appropriate “ C O 2 ” or “ fiber ”. Adjust the height of the table, you need the stock to contact the “leg” without pushing it outside it rack.


Press the laser button to see the laser on your stock.


Move the laser head and then select the origin.


Press the joystick to confirm the origin location


On the computer open corel draw, import your file, set the line width to “hairline”. Them CTRL+P







Select the fusion M2 in the print menu.


In preference set the power, speed and depending on your material.


Hit the green run button on the laser control panel

Laser cutter focus, power, and speed



Laser cutter focus is done with the appropriate tool for CO2 and fiber laser.


Laser cutter power is 75 Watt for the CO2 laser and 30 Watt for the fiber laser.


The speed of the laser cutter is set in % in preferences in the print menu.

Laser cut rate, kerf and joint clearance

Remix of the board game Settlers of Catan

The game

Source: Catan article from Wikipedia

"Catan is a multiplayer board game designed by Klaus Teuber, and first published in 1995 in Germany by Franckh-Kosmos Verlag (Kosmos) as Die Siedler von Catan. Players take on the roles of settlers, each attempting to build and develop holdings while trading and acquiring resources. Players gain points as their settlements grow, the first to reach a set number of points, typically 10, wins". "The players in the game represent settlers establishing settlements on the island of Catan. Players build settlements, cities, and roads to connect them as they settle the island. The game board, which represents the island, is composed of hexagonal tiles (hexes) of different land types, which are laid out randomly at the beginning of each game"



The figure below shows a game of Catan with the extension city and Knight I played with my brothers.


A game of Catan with the extension city and Knight


My goal was to remix the game with a japanese version made almost only on the laser cutter.

Design

Bellow are the OpenSCAD files used for the design of the game remix:

Laser cut game

OpenSCAD design
I use the following design and color scheme to rmix the tiles:


Tiles


Ninja robber


Player pieces


Overview
Testing improvement to the base game
I wanted the design of the tiles to allow to lock the roads, boats and pieces in place during the play.

I also wanted to use origami helmet (kabuto) to mark the power of the samurais (knights): I am also planning to use an origami kabuto with a laser cut stand for the largest army trophy.


Testing roads between tiles and base for the pieces


Samurai origami helmets for level of power!
Painting


Unpainted tiles

Drying


Painted tiles
I used water based paint.

I might want to add a protective coat latter.



First results
I need to laser cut more parts to have a full game.

I do like the look of the remix game!

Now I can make as many tiles I like to create custom large maps :)


Catan Island


More tiles!!
