+* Dangerous and forbidden materials
-* Special Materials (for example: special acrylic for glow effects and cooling for glas engraving)
+* Special materials (for example: special acrylic for glow effects and cooling for glas engraving)
-* What is the precision of the laser cutter (it's generally in the tenths of a millimeter but it highly depends on the material and the calibration of the laser cutter. for example: acrylic is more precise than wood)
+* What is the precision of the laser cutter (it's generally in the tenths of a millimeter but it highly depends on the material and the calibration of the laser cutter. for example: cutting acrylic is more precise than wood)
 * Explain that the laser cutter doesn't cut perfectly vertical and the cut is widening towards the bottom of the material
 * Explain that there are different conventions on how to prepare a laser cutter model for different laser cutters. So be careful when using models from Thingiverse.

 === Introducing people to the Laser Cutter ===
-* First show them where the fire extinguisher resides and how to use it.
+* First show them where the fire extinguisher resides and how to use it. Also tell them to use '''this''' and no other fire extinguisher because it's a CO2 type.
 * Explain roughly how the laser cutter works
 * Show them how to clean the lens, mirrors and laser bed

 * Explain how the primary settings of the laser cutter work (for example: lowering the speed to gain even more power)
 * Show them the sheet with the reference settings
-* Load the test cut into Ctrl-Cut
+* Show them how to assign objects to layers
-* Show them how to properly align the cut job (ctrl-T shortcut)
+* Show them how to assign settings to layers
-* Show them how to use the lower-to-bottom feature (right-click on an item)
+* Show them how to align objects
-* Show them how to use copy 'n' paste settings feature (right-click on an item)
+* Show them how to transfer a job to the laser
-* Explain all settings from top to bottom
+* Show them how to do the accounting with our spreadsheet
-** The title will be shown on the laser cutter display
-** The auto focus checkbox activates/deactivate auto focus
-** The Unit dropbox sets the units used in the program '''Globally'''
-** Mention the center engrave feature, but tell them to read up on it in the user manual and to ask for assistance the first time they wanna use it
-** Mention the Air Assist feature, but also tell them it is dangerous to deactivate it. If the wanna use it they need to ask for assistance
-** Explain why to use Inner-Outter sorting and when to use the faster TSP sorting
-** Explain that sometimes it's better to use bottom-up engraving direction (for example: for wood)
-** Explain that dithering influences the quality of engravings and that the right choice depends on the picture (Generally, if the picture is rather uniformly areal and has sharp edges they should use bayer. If it is a more natural picture with gradients and fuzzy edges, like a portrait, they should use Floyd-Steinberg).
-** Explain that the program does automatic adjustments (like contrast stetching) to '''color''' and '''greyscale''' images. If they import a monochrome image not automatic adjustments will take place.
-** Tell them always to use the preview feature and inspect it. It prevents mistakes and also protects against software bugs.
-** Show them how to use the color mapping feature
-** Show them how to do the accounting with our spreadsheet
