Week 2
Lets play with machines
Vinyl Cutter
Roland Camm -1 Installation
First time setup (software force control in fab modules)
Go to http://localhost:631/ in browser
Using C Unix Printing System (CUPS 1.7.2) create a new profile for the vinyl cutter. Name should be "vinyl"
and it is case sensitive
Vinyl sheet loaded properly in the vinyl cutter.Fix the vinyl sheet between the white marked area clse to left side of the vinyl cutter machine
Cover the Sensor
Align the material
Set Orgin : position the origin using right,left,up and down key. Once its done press and hold the origin button
(3 seconds)
The test cut
Adjusting Force/Adjusting blade length
Remove the circle without removing the square

Laser Cutter
Install Laser printer software.
Design in Inkscape and then the saved .svg file is given as input to the Laser cutter.
laser cutter cuts/engraves by burning the material
Focus the lens by adjusting the material surface.

Danger of a Laser Class 4 beam
Machine has built in protection
Do not try to mess or hack the lid. It's not cool
Fire
NEVER leave a laser cutter unattended. EVER
If you ever see an unattended laser machine working: SHUT IT DOWN
Check your design against double lines
Check your design against heat concentration (can the material handle it?)
Not laserable products:
Vinyl
PVC
Any unknown material
Laserable things
Anything specifically made to be laserable
Acrylic
Cardboard
Wood
Natural fibers and leather
In general, all Natural materials
Laserable things that are not recommended
The risk of Long term exposure to chemicals
MDF
Anything laserable that you think it might contain traces of nasty things (glues, paints, coatings…)

Copy the Gcode to SD card and print

Molding and Casting
Designing sigle sided mold in antimony
Forward design (start with the castable object) vs backwards design (start with the wax you have)
Silicon clearance
Wax clearance
Advantages of antimony
DESIGN FOR the tool you have or BUY A TOOL for the job you want to mill
Inner corner limitation and design workaround
Tool depth limitation
Clearance parameter in fab modules (compiled version only)
Roland Modela
Mixing Pay attention. By volume not necessarily equal to by weight!!!
Remember. Expensive material. Calculate silicon volume or weight and allow 25% extra
