-  * Where Mach3 is mentioned, we use bCNC 
-  * The hackspace CNC is designed for use with metals not wood due to fire risk, but the principals in the video are the same

 +    * Don't open the cover when it is spinning

-  ​Don't cut wood  +    ​External extraction is planned 
-    * It creates a flammable cloud of sawdust+    * An interim solution has been to use the portable sawdust extractor to catch the cloud from the top of the machine. The filters/​dust inside seem to work well at removing the (very small volume of) oil from the air 
 +  * Dust clouds can be flammable ​ 
 +    * Especially true if cutting wood 
 +    * The portable dust extractor can remove the dust cloud from the top of the machine. A better attachment is needed (want to be amazing and help the space? create this attachment!)
   * Metal chips can scratch your eyes   * Metal chips can scratch your eyes
     * They will likely get stuck to the door, and then fall on you when you open it. Watch out for this!     * They will likely get stuck to the door, and then fall on you when you open it. Watch out for this!
 +====How do I make something with it?====
 +  * Have you watched the videos linked further up the page?
 +    * watch them
 +  * design your part in CAD software
 +  * use CAM (computer-aided manufacture) software to create the g code (.nc file)
 +  * transfer this to the CNC mill computer
 +  * on the desktop, press "run bCNC"
 +    * [[https://​github.com/​vlachoudis/​bCNC/​blob/​master/​README.md|Wiki page for bCNC]]
 +    * this is the control software
 +  * Connect to the machine through COM 4 (probably)
 +  * press home
 +  * zero each axis on the workpiece
 +    * you did set the origin to a sensible point didn't you?
 +  * press play
 +  * you will have made a mistake in your setup, accept this
 +    * PLACE YOUR HAND ON THE KILL SWITCH, READY TO PREVENT THE INEVITABLE CRASH!!!
 +    * grumble to yourself and others
 +    * try again
 +
 +====Am I allowed to/how do I/would it work if I?====
 +  * Yes, probably, or possibly no
 +  * the machine is extremely versatile, so all eventualities can't be covered on a Wiki page
 +  * don't be afraid to experiment, but be sensible when you do
 +  * someone on youTube has probably done it. take a look
 +
 +====Oh no, I've broken the CNC mill!====
 +  * This may happen at some point
 +  * clearly, you're smart enough to make the machine move. Therefore, attempt to repair it.
 +  * put a post on the google group
 +  * put a label on the machine
