+====== xTool S1 Diode Laser ======
+The xTool S1 is a 20W 455nm (blue, #0061ff) diode laser with a 608 x 385mm bed and a maximum material thickness of 42mm.
+<callout title="Induction Required" type="danger" icon="true"> This equipment requires an induction prior to use. For your own safety and to avoid damage to the equipment do not attempt to use it until you have been inducted. </callout>
+<callout title="Crush / Burn Hazard" type="warning" icon="true"> This equipment is hazardous to the user or those around them, take care during use.</callout>
+Our setup includes the honeycomb panel and air assist. With the honeycomb panel installed the maximum material thickness is 15mm.
+See [[equipment:laser:laser-xtool-s1:lightburn]] for a step by step guide.
+===== Materials =====
+The materials approved for use on the diode laser are mostly the same as the other laser with important additional restrictions.
+==== Approved Materials ====
+Only the following materials may be used with the xTool laser cutter (subject to additional restrictions below):
+  * Solid wood sheets
+  * Plywood - not marine ply
+  * MDF
+  * Non PVC composite woods
+  * Paper/Card (See additional restrictions)
+  * Cardboard (See additional restrictions)
+  * Foamboard - non PVC or other banned material (See additional restrictions)
+  * Acrylic/Plexiglas/PMMA (See additional restrictions)
+  * Acetal/Delryn/POM (See additional restrictions)
+  * Non PVC rubber (such as EPDM) (See additional restrictions)
+  * Cotton/Hemp based textiles [[https://www.xtool.com/blogs/xtool-academy/laser-cutting-fabric]]
+  * Untreated real leather [[https://www.xtool.com/blogs/xtool-academy/leather-laser-engraving]]
+=== Additional Restrictions ===
+The laser uses blue light, materials reflective or transparent to blue light will not work.
+{{equipment:laser:laser-xtool-s1:laser-blue.png?100|}}
+Materials with colours inside the black dashed line may not work very well.
+{{equipment:laser:laser-xtool-s1:xtool-s1-color-guide-small.png?400|}}
+Do not attempt to cut clear, white or blue plastics such as Acrylic, Plexiglas etc.
+==== Banned Materials ====
+The following materials are banned for safety reasons, because they give off highly toxic fumes, are a fire risk, or may damage the machine.
+  * PVC/Vinyl - __releases Chlorine which will damage the laser__
+  * Polycarbonate
+  * ABS
+  * Polyethylene (PE / HDPE)
+  * Styrene / Polystyrene / HIPS
+  * Polyethylene (PET / PETG)
+  * Nylon (PA)
+  * Treated or coated real leather
+  * Vegan leather
+  * Epoxy and similar resin materials
+  * Carbon fibre composite
+  * Fibreglass - both raw glass fibre and finished composite
+  * Any other material containing Bromine (Br), Chlorine (Cl), Flourine (F), or Iodine (I) in its chemical formula
+  * Any other material containing a CN bond (Carbon-Nitrogen) in its chemical formula
+  * Any other material advertised as fireproof / flame retardant
+  * Any metals (pending risk assessment and review)
+  * Food - do not eat anything out of the laser cutter
+===== Safety =====
+  * Do not defeat the interlock
+  * Do not disable the fire detection system
+  * Only use approved materials
+  * Actively supervise the laser cutter while cutting
+  * Do not turn off the blower unless you are certain it is necessary
+The laser module can move with the lid open. Ensure fingers and hands are clear when:
+  * Turning on
+  * Jogging the tool in software
+  * Homing
+  * Resetting after emergency stop
+  * Running "Detect" operations
+==== Emergency Stop ====
+The emergency stop button is located on the right side of the laser cutter at the back.
+{{equipment:laser:laser-xtool-s1:xtool-s1-estop-right.jpg?400|}}
+Also indicated with the red arrow below:
+{{equipment:laser:laser-xtool-s1:xtool-s1-estop-front.jpg?400|}}
+Other ways of stopping the laser include:
+  * The button on the front - when running this acts as a "Pause" button
+  * The software "Stop" button in LightBurn
+  * The right-hand isolator switch
+==== Fire ====
+Flammable materials like wood, paper and plastic can catch fire when cutting. __**You must actively supervise all laser cutting**__ and be prepared to stop the machine if a fire breaks out.
+Only use a CO2 fire extinguisher with the laser. This is located next to the door to the CNC room, directly behind you when facing the laser.
+{{equipment:laser:laser-xtool-s1:cnc-room-co2-fire.jpg?400|}}
+Before starting any work with the laser ensure the surrounding area is clear of flammable materials, especially volatile substances like isopropyl alcohol.
+If a fire breaks out while using the laser stop the job immediately, do not assume that the on-board fire detection system will work. Use any of the following:
+  * The "Stop" button on the PC.
+  * The button on the front of the machine ("Pause" if a job is running).
+  * The emergency stop button
+  * The isolator switch
+If it is safe to do so continue to tackle the fire with the CO2 fire extinguisher.
+If the fire has spread beyond the confines of the machine follow the Hackspace [[manual:fire|]] procedure.
