 Objectives for basic use:
-  * awareness of laser and voltage risks, and which parts of the cutter should remain off-limits
+  * Awareness that the laser can cause burns and blindness, that the laser compartment must remain closed, and the lid-sensor must not be bypassed.
-  * powering-up and checking that the cooling and extraction are working
+  * Awareness that the laser cutter contains high voltages (2kV, 240V) and that users must keep clear of the wiring in the laser compartment and control panel.
-  * know which materials may be cut safely (fire/fume risks) and without damaging the cutter with Chlorine (PVC)
+  * Know how to power-up the cutter and checking that the extraction, water cooling and air assist are working.
-  * the importance of monitoring the cutter while it is active (fire risks)
+  * Know which materials may be cut safely, that some plastics may produce chlorine or cyanide gases, and that some materials may catch fire more easily than others.
-  * checking the coolant temperature
+  * Know that there is risk of fire with *any* material and that the cutter must not be left unattended, even for a minute. Know that there is a pause function and an emergency stop.
-  * basic use of the software
+  * Know that the cutter works best with coolant temperature between 10-20C, should not usually be used above 25C, and how to check the temperature.
+  * Basic use of the software.
   * setting appropriate power/speeds for different materials
   * using the cutter's control panel to move the head/carriage
