Before your Emblaser 2 will allow the laser to emit laser light, it must be manually ‘enabled’.
This is achieved by pressing the ‘Enable’ button on the front right corner of the Emblaser 2 when the lid is closed.
The ‘Enable’ button will light up ‘red’ when successfully enabled.

Action Result
Upon Power Up When the Emblaser 2 is turned on the laser is kept in a safe

‘disabled’ mode. This is indicated by the ‘enable’ button not lit.
Lid Closed + Enable| With the lid closed, the laser can be enabled by pressing the ‘Enable’ button. This is indicated by the ‘enable’ button being lit.
Lid Open when Enabled| The laser will immediately become ‘disabled’ when the lid is opened. This is indicated by the enable button light turning off.
Lid Open + Enable| The laser will not ‘enable’ if the lid is open.

** It is recommended that you ‘enable’ the laser only when ready to cut or engrave.
It’s a good habit to ‘disable’ the laser at all other times.
Laser Height Control
The Emblaser 2 has the unique ability to set the height of the laser above the workpiece via software. There is no need to manually adjust the laser height when working with materials as the software sets this for you. Laser height control also allows you to control the laser height during multi-pass jobs, changing the laser height automatically during each pass.Darkly Labs

Health Warning Information

Color Blindness
The small percentage of the population (0.01%) that have blue-yellow colour blindness (tritanopia) may struggle to see the Emblaser 2 indicator lights and may not realise the laser system is ‘enabled’. Tritanopic users must therefore be particularly careful.
Hypersensitivity
Isocyanate exposure from thermally degraded polyurethanes has the potential to cause hypersensitivity to develop over time in predisposed individuals, which can lead to subsequent life threatening asthma like reactions on re- exposure to even trace amounts.  Recommendations:
Those with a history of asthma should avoid laser cutting polyurethanes.
If a wheeze develops during or after cutting polyurethanes in any user, further polyurethane cutting should cease and medical advice should be sought.
Isocyanate by products from decomposition of polyurethanes can remain in exhaust ducting and can still cause sensitisation with skin contact.
If you get a sore throat or eyes while laser cutting polyurethanes, you have developed  isocyanate pharyngitis and your precautions are not working effectively.
Airway Irritation
Many of the chemicals liberated by laser cutting and engraving have the potential to cause airway irritation, but few, if any, permanent effects. Some of the chemicals are known carcinogens, but with appropriate local or general exhaust ventilation, exposures are  unlikely to add significantly to background environmental exposures (i.e. formaldehyde from MDF furniture, benzene in fuels).
If you are experiencing airway irritation, your ventilation is not adequate.
Exposure to fumes from laser cutting
The heating which occurs during laser cutting or engraving can cause charring, pyrolysis and even combustion of the material being worked on.
Exposure to the fumes and particulates released during laser engraving or cutting can cause irritation to the airways and potentially be extremely dangerous.
For example, exposure to Isocyanate from thermally degraded polyurethanes has the potential to cause hypersensitivity to develop over time in predisposed individuals, which can lead to subsequent life threatening asthma like reactions on re-exposure to even trace amounts.
Important: See Appendix for information on chemical reactions with various materials during laser cutting and engraving. Always research the material you plan to work with to ensure it is safe to do so.
Always follow your local Occupational Health and Safety (OH&S) rules
Ensure that you comply with local occupational health and safety legislation. Failing to do so could put you in breach of the law. Even if not being used in a business, owners may be in breach of the law if injuries occur, since injury to a member of the general public could conceivably constitute a breach of the owner’s OH&S obligation under law, subject to penalties.
Visit your local government website for OH&S information on laser safety requirements.
Those operating the Emblaser within an established business should nominate a designated  laser safety officer, responsible for the safe use, training, and upkeep of the Emblaser and associated personal protective equipment, administrative controls such as user credentialing and safe operating procedures (SOPs), and engineering controls, such as ventilation
Fire
A laser cutter / engraver works by amplifying light to such a degree as to either melt or burn material while following a designated path. The heat generated during this process could potentially cause combustion (fire) within the material being worked on.
Ideally, a smoke / fire detector should be installed in the area the Emblaser 2 is being used.
A fire blanket and smoke extinguisher should always be readily accessible.
