Yueming PN1490 Laser Cutter

In order to get inducted on the laser cutter, you need to go to the following Eventbrite event and book a place for yourself on one of the available dates.

CO2 Lasers induction

Inductions happen fortnightly.

• Inductions signups close 3 days before the event start. This allows volunteers to organise their life.
• If no one has signed up for the date before it closes, the induction is cancelled.
• If the induction is on (because people signed up in time), but the time has passed, you can always ask in discord if you can get into the induction.

You can find all sorts of information on LightBurn Software Documentation

You can watch all the tutorials HERE

This is the documentation we use to give the inductions. It's always being updated and you can always find the latest version here.

• When operating this machine, under absolutely NO circumstances must it be left unattended.
• If anything goes wrong, your first port of call is to always bang the big, red Emergency Stop button. It's there for a reason, don't be afraid of using it. Even the resident laser cutter experts have to hit it every so often, because things happen.
• Try to avoid staring at the cutting point. We know it's pretty & oh-so-mesmerising to watch, but it's very bright & you'll end up with temporary spots in your vision.
• Only cut approved materials that are known to be safe. If you disobey this rule, you will create toxic fumes potent enough to put you in hospital and/or you'll generate gaseous forms of very strong acids which will literally eat away & dissolve the machine's insides.
• The nearest fire extinguisher is by the door to this room. Don't use the fire extinguisher unless it's necessary, but if the situation calls for it don't hesitate for one second because a fire will spread very quickly inside the machine. Having to thoroughly clean & align a laser cutter is a pain but it's far better than having to replace a burnt-out shell of an ex laser cutter.

Caution – use of controls, adjustments, performance of procedures other than those specified here in may result in hazardous laser radiation exposure. Before starting cleaning or maintenance work always switch off the device at the interlock level. Always keep the system clean, as flammable parts in the working area or exhaust area rise the fire hazard.

The cleaning interval strongly depends on the material that is being processed and the operating time of the device. Please bear in mind that only a clean machine guarantees optimal performance and reduces our service costs.
