 . Use the machine if the extraction is not working.
+==== Notes from another induction, to be integrated====
+to be integrated in to page.
+  - Never leave unattended
+  - Always use the Emergency Stop button that is on the laser before the one on the wall, and especially so in emergency - this allows the water cooler and extractor to stay on and help put out any fires, reduce damage, etc.
+  - Laser MUST be below 24c, better to be less than 21c. Read the temperature from the refrigerator unit. In the warm months, it can take 10+ minutes to come down to temperature.
+Materials:
+  - [[:equipment:cnc:laser:materials|Full Materials List]]
+  - Absolutely no PVC. The "Chloride" part of Poly Vinyl Chloride vapourises in to chlorine gas and can't be easily extracted by the extractor. Be extra sure of materials as some look confusing.
+  - It won't cut steel or aluminium
+  - it can supposedly surface engrave anodized aluminium, or alumium that has been treated with a special spray. ask around on the forum before attempting to do so.
+  - Acrylic 4mm will be cut through at 12-15mm/s
+  - If you're unsure of laser power, do test cuts e.g. a few squares in the corner of your workpiece to work out how slow to cut through
+Files:
+  - Must export in DXF
+  - Must be in mm
+  - Open Lasercut5.3 on the PC.
+  - Import DXF
+  - Tools > unite lines.
+  - Change scale, type X width then click 3 dots on y to set proportional scale.
+  - "Pick" tool to move things
+  - Use different colours to create layers
+  - Double-click colour to open options
+  - Generally always blow
+  - Speed is measured in mm/s
+  - Corner power - can reduce
+  - Layers work in order, top first.
+  - Generally want to engrave then cut, to prevent movement.
+  - To just engrave, put 70mm, 50% for acrylic
+  - Engrave Mode setting will engrave the internal area of a shape.
+  - Cut Mode will cut on the lines.
+  - Unsure of other modes.
+  - Need to Set Knife Origin in the application, to let it know where to start the laser from.
+  - Click Download, Delete All (clear queue), Download Current
+Laser:
+  - Position laser, then material
+  - Press enter, then enter again, SET LOGIC ORG (ORIGIN).
+  - Do test button to trace outline of cut.
+  - Press Z button to start changing height, then up and down. Press Z again to exit height mode.
+  - Use little wooden tool to ensure bed height is correct
+  - Never push Datum in Z mode. There is no safety switch in Z mode, so it would keep lifting the bed and crash it in to the laser.
+  - ESC is your friend
+  - Wait 10 seconds for extractor to finish extracting after finishing cutting.
