'''DO NOT HANDLE THE LAZZZOR IF YOU ARE NOT AUTHORIZED TO'''.
  
''this is a very very early draft for a yet-to-come howto 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''

Only [[Lazzzorauth]] key owners are able to operate the mighty Lazzzor. If you are authorized as well '''because you've successfully completed a [[Lazzzor_Cutter_Workshop]] _AND_ you've been given approval by one of the [http://metalab.at/wiki/Lazzzor#Willst_du_etwas_lasern.3F laser admins]''' you may request your own [[Lazzzorauth]] iButton.
  
  
so, you want to use the mighty fine lazzzor yesyes?

'''All others will need a assisting* key owner that is responsible for safe operation.'''</div>
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:

Amongst others some friendly helpers are:
* cutting: for this you need a vector graphic,

{{Lasermenschen}}
* 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.

engraving / raster format:
 
* convert your image file to grayscale

* you can set the DPI for your graphic up to 1200 (max. setting the lazzzor supports)
 
* no background color (means: transparent background)
 
 
 
 
 
software recommendations: ...
 
 
 
 
 
== 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 wont need as much Power and/or Frequency.. see theoretical experiments for further help. (insert link!)<br>
 
<br>
 
''Job''
 
: '''Raster''': for engraving
 
: '''Vector''': for cutting
 
: '''Combined''': for doing both! Engraving always comes first.
 
<br>
 
''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.
 
<br>
 
''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. (price, costs, material category?)
 
 
 
=== 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 ===
 
anything which got Chlorine (Chlor) or Nitrogen (Stickstoff) in it. bad stuff will happen if it combusts.
 
some examples:
 
* PVC
 
* PC
 
* Polyurethan (found in sponges for cleaning dishes)
 
 
 
other potential dangerous stuffs:
 
* BoPET Foil: as used in rescure blankets. has the ability to reflect big part of the IR spectrum. omg.
 
* ...
 
 
 
should some materials be forbidden which are already used?

== 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!)
 
 
 
Before everything starts:
 
'''IN CASE OF FIRE''' - only use the CO2 fire extinguisher on the left side - a short burst should suffice to kill the flames. (include pic).
 
 
 
2 important buttons:
 
* "Go" aka Green Button aka "yea go that."
 
* "Stop" aka Red Button aka "no way, dont do that."
 
 
 
'''IMPORTANT IMPORTANT IMPORTANT IMPORTANT IMPORTANT IMPORTANT'''
 
'''[[before you start a job ALWAYS TURN ON THE BELÜFTUNG]]''' (picture of buttons)
 
'''IMPORTANT IMPORTANT IMPORTANT IMPORTANT IMPORTANT IMPORTANT'''
 
 
 
=== how to set your 0-point. ===
 
its a good idea to set your home-point everytime before a different job.
 
this point is the starting position and represents the upper left corner
 
in your image / workspace area.
 
 
 
# press "Pointer" (or what was it?) to make it visible/invisible
 
# press "X/Y", the display will say "X/Y - Off"
 
# you can now move the lazzzor freely along its x and y axis
 
# press "Set-Home" to set your position as your home-point.

=== 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 now, go on, push teh button!..

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

Before you begin you should know..

DO NOT HANDLE THE LAZZZOR IF YOU ARE NOT AUTHORIZED TO.

Only Lazzzorauth key owners are able to operate the mighty Lazzzor. If you are authorized as well because you've successfully completed a Lazzzor_Cutter_Workshop _AND_ you've been given approval by one of the laser admins you may request your own Lazzzorauth iButton.


All others will need a assisting* key owner that is responsible for safe operation.

Amongst others some friendly helpers are:

anlumo, ripper, luto, ...


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 raster 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.

for both: your image/graphic should fit into the workspace which is 1300mmx900mm big. Cutting / Vector format:

  • deactivate filling on all objects
  • set the stroke width on all objects to 0.001 inch (or hairline)

** watch out for duplicated vectors lying on top of each other. it results in the line being cut twice. Ctrl-Cut automatically handles duplicate lines.

  • export your model in pdf format (it is also possible to use ai, ps, eps, ctrl-cut vector format and svg, but pdf is highly recommended).

Engraving / Raster format:

  • Our current laser cutter has a fixed resolution of 100 DPI.
  • Ctrl-Cut supports automatic conversion to grayscale and stretching the contrast, but if you convert the image to monochrome (1-bit) _before_ importing it won't adjust the image at all, so you can manually tweak it.

Repeating Lazzzor Jobs

Using Ctrl-Cut you can save lazzzor cutter jobs with all settings and optimizations applied as .cut file. Next time just open it and press "Send",

Color Mapping

If you use different colors for vectors in your file, Ctrl-Cut automatically creates different cut items, that you can apply settings to individually.

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.
