Follow the instructions to turn the machine on and off. 

[[Power Up and Power Down (Laser Cutters)]]

== Fire during a laser cutting job ==

* You must stay with the laser cutter at all times while it is running, and monitor it for fire. 
* Flames which travel with the laser cutter head are normal. In the event of flames in an area which is not currently being cut by the laser '''immediately''' press the emergency stop button on the top of the machine.
* Shout "Fire!" to alert otheres around you and gain attention of the Maker Space staff.
* Use your judgement to determine the severity of the fire. 
** Small flames may be extinguished if it is safe to do so.
** In the event of a large fire do not open the lid of the laser cutter and exit the Maker Space via the nearest emergency exit.
* There should never be a large, out of control fire in the laser cutter because users are monitoring the laser at all times when it is running.

== Tips for using this equipment ==

=== Always keep an eye on your cutting job ===
The laser cutter works by selectively burning your material. If your settings are incorrect, or the laser cutter software crashes, then there is a risk of fire. If this occurs, press the emergency stop button and inform a member of staff immediately. There is a CO2 fire extinguisher located next to the fire exit door by the laser cutters. 

=== Turn on the fume extraction ===
You must use the fume extraction when laser cutting. Not using the extraction exposes all users of the Maker Space to hazardous combustion by products, fills the room with smoke, and will set off the fire alarm.

The fume extraction power switch is located on the wall opposite the door to the technician’s office.  

=== Cover cut edges with masking tape ===
Cutting wood products like MDF and plywood can result in a sooty burn mark. Cover the areas you will be cutting through with masking tape on both sides before cutting. When you peel the tape off the sooty marks should be on the tape!

=== Use a vector mark to speed up detailed line engravings ===
If you have a lot of lines to grave you may find it quicker to use a very light vector cut instead of an engrave. Use a high speed (100%) and a low laser power (10-20% depending on material) to score the top surface of MDF and plywood without cutting all the way through.  

=== Experiment with the laser settings ===
Try out the laser settings on an offcut or scrap before committing to a full sheet. Sometimes you can get away with less power or more speed. Keep a note of settings which work well for you!

=== Use material offcuts before cutting into a fresh sheet ===
Material is becoming more expensive – try to use offcuts wherever possible, even if it means splitting one job into several smaller jobs.

=== Nest your work efficiently ===
Make sure that you are [[Material Nesting|making the most effective use of the material]] which is being provided. Excessive material wastage may result in the Maker Space charging for material in the future.
