 Before cutting/engraving:
-* Wait for at least 5 minutes before firing the laser (laser temperature has to be constant).
+* Wait for at least 5 minutes before firing the laser (warm-up phase).
 * Ensure that the air filter is on before firing the laser. For extended use (>= 30 min), it is recommended to wear a mask as a personal safety measure.
 * If possible: open the windows to create an air current and help evacuating the fumes outside the room.
 * Always calibrate the height of the bed AFTER adding material in the laser cutter. This is done by using the 4.1 mm calibration tool.
 * Always specify the settings in software (do not change them in the machine).

 * Assuming the laser cutter cuts in the XY plane, the cuts along the X-direction and Y-direction will not be the same.
 * The intensity of the laser is not uniform on the cutting bed. The cuts have lesser errors in the Upper Left and Lower Right regions of the bed.

+It works with its own proprietary project format, as well as with other formats (AutoCAD, Illustrator, etc).
 Still, these formats are not considered as standard by the program - you have to import the sketches into the software to use them
 and edit them. One convenient format used is .DXF, which is the AutoCAD format.
