How to Lazzzor or "Why you won't use scissors anymore."

This is a very very early draft for a yet-to-come how to lazzor page. The main source of information was the lazzzor workshop held on 2011-01-27. Feel free to add/edit information, suggestions or similar. you can do so in English or German. Also: it doesn't need to be perfect, but the information supplied should be correct or if not, labeled accordingly

Update: seems everything essential is covered. Some pics may follow.


So, you want to use the mighty fine lazzzor yesyes? Then you will have to complete several trials to step up to the throne of being a lazzzor king or queen.

Basically, you have 2 options:

  • cutting: for this you need a vector graphic,
  • engraving: for this you need a rasterized image

You can also do both! if you put a rasterized object inside a vector graphic. Alternatively you can create a separate file for each job.

prepare your image

Get your favorite vector/raster drawing program and draw some stuff you want to have cut or engraved. Depending on what you want to do, your image file is qualified for print if the following things apply.

Cutting / Vector format:

  • deactivate filling on all objects
  • set the stroke width on all objects to 0
  • export your image in *.eps format [.. other recommended formats here.] we strongly encourage you NOT to use dxf formats. They are prone to errors when imported into Corel Draw (which will be used to send the job).
  • During exporting/saving, look for an option which says "Make a bounding box around full page" or similar and DEactivate it.

Engraving / Raster format:

  • convert your image file to gray scale
  • play around with the Level option to get the highest contrast possible
  • you can set the DPI for your graphic up to 1200 (max. setting the lazzzor supports)
  • no background color (means: transparent background)


Software..

  • ..for raster images: Photoshop, Gimp, MS Paint, .. any common image editor.
  • ..for vector graphics: Inkscape, CAD programs, Adobe Illustrator, ...


If you finished your image/graphics ...

  • Bring your image/graphic on a USB drive to our lab and plug it into the cutting station next to the lazzzor.
  • Import your File in Corel Draw x4 and check if every requirements have been met as listed above.
  • Go to file > print (Datei > Drucken...), select the lazzzor.
  • Click on properties (Eigenschaften) and you are ready to advance to the next stage.

The printer dialog

(screen caps?)

main tab

Laser

Power, how much power to put into each lazzzor shot. for cutting, you want to use as little power as possible
Speed, how fast the lazzzor moves.
Frequency, how many times a lazzzor shot happens. This depends greatly on the material used.

These 3 parameters kinda intervene with each other. E.g. if you lower the Speed, you won’t need as much Power and/or Frequency.. See theoretical experiments for further help. (Insert link!)

Job

Raster: for engraving
Vector: for cutting
Combined: for doing both! Engraving always comes first.


Rasterisation

basic: makes it look good, most of the time you'll want to use this.
3D: good for making stuff like holes for screws.
stamp: yeah, that's for stamps, there are also 2 additional parameters for this one. (todo: indepth howto for stamps)


misc

Auto focus: important for making nice cuts, you also can do that manually (todo)
Frequency Automatic: not tested yet! But it obviously states what it does, yes?
Vector Sorting: algorithm which should calculate a good way to cut stuff. You probably should use a good image instead of relying on this, but most of the time it shouldn't cause any problems.

user settings

Here you can load and save settings created by other users.

warning! this doesn't mean they are automagically the best choice for your job! In some cases, quite the opposite is the case and you might end up damaging your material or the lazzzor. Still, in combination with the Cheat sheet included in the manual, you can figure out if there are some reasonable settings too.

Color Mapping

Depending on the colors you gave your vectors; you can set individual Power, Speed and Frequency settings for each color! Might come in handy, but most of the time you won't need it.

The Materials

If you want to cut or engrave something, bring your own material, though you can also use any leftovers or stuff which does not have a label on it. (of course labels which say "free for all" are ok, too). Feel free to donate a little extra if you use some materials.

allowed

Cutting / Engraving:

  • Anything made out of wood
  • Acrylic
  • Polypropylene
  • Polystyrol (low Power & Speed!)
  • Fabric (hm what about polyester?)
  • ...
  • Very very thin metals (foil or curcuit board made out of Messing) (--> indepth howto at example page?)

Engraving:

  • Glass
  • ...

forbidden

Any material with Chlorine (Chlor) or Nitrogen (Stickstoff) as a compound. Dangerous fumes will be emitted when burned. Some examples:

  • PVC
  • PC
  • Polyurethan (found in sponges for cleaning dishes)
  • ABS

Other potential dangerous stuffs:

  • BoPET Foil: as used in rescure blankets. has the ability to reflect big part of the IR spectrum. omg.
  • ...

todo: should some materials be forbidden which are already used? special workflow instructions on potential dangerous materials! --> http://entropie.digital.udk-berlin.de/wiki/Laser_Cutter#FORBIDDEN_MATERIALS

to the lazzzor!

you have sent your job to the lazzzor and chosen your material of choice, now off you go my friend, you are a big boy/girl now, but still, there are some buttons you have to get familiar with first. (pwetty pictures!)

2 important buttons:

  • "Go" aka Green Button aka "yea do that."
  • "Stop" aka Red Button aka "no way, don’t do that."
 IMPORTANT ------ IMPORTANT ------ IMPORTANT 
 BEFORE you start a job always TURN ON THE BELÜFTUNG
 IN CASE OF FIRE - only use the CO2 fire extinguisher on the left side (todo: include pic) 
 a short burst should suffice to kill the flames.
 IMPORTANT ------ IMPORTANT ------ IMPORTANT 

how to set your 0-point.

It’s a good idea to set your home-point every time before a different job. This point is the starting position and represents the upper left corner in your image / workspace area.

  1. press "Pointer" (or what was it?) to make it visible/invisible
  2. press "X/Y", the display will say "X/Y - Off"
  3. you can now move the lazzzor freely along its x and y axis
  4. press "Set-Home" to set your position as your home-point.

 BEFORE you start a job always TURN ON THE BELÜFTUNG

when to cancel/pause your job!

if you ...

  • .. hear noises you are not used to hear
  • .. see smoke gathering in the cutting area
  • .. see something burning constantly. (One or two spurts of flame are okay when cutting acryl (i think it was acryl?))

Now, go on, push teh button!..

how to start, pause and cancel your job!

Final preparations:

  • place the material inside the workspace of the lazzzor.
  • If you haven’t already done so, set your home position described above. its a handy thing to do.


Starting a job:

  • The display of the lazzzor should read something like "Job: #1 ... ".
thats most likely your job if you just turned on the lazzzor.
  • press "Go" to start the job


Pause/Cancel a job

  • press "Stop" at any given time to halt the lazzzoring process
    • press "Go" to continue your job.
    • press "Stop" again to cancel your job (which is more likely if you got this far :p)

possible misc ideas:

  • die klappe besser abdichten mit nem gummi oder so.. auch praktisch beim zumachen damits nicht zukrachen bzw zerbrechen kann
  • tatsächliche schadstoffe in der luft messen, was für ein gerät braucht man da? interessant wärs schon

taking care of the lazzor (separate page!)

  • if you think your settings are pretty much okay but it still won’t cut through then there is a possibility that the lazzzor needs some cleaning.
  • gets s seperate "how to"

Some practical examples: (separate page?)

These (useful?) things are what people actually made and hopefully documented it for others to use. (hint hint)

Some theoretical/experimental examples: (separate page?)

This section explores different possibilities of parameters and their outcome. This is a good place to get you an idea on how to fine tune your parameters.

Material:

  • The material
    • different parameters 1
    • different parameters 2
    • different parameters 3
  • Soap
    • engraving a soap ended in the soap swelling, or so I’ve heard.
