== In case of fire ==
 +
 
 +
* Small fire: open lid, try to blow it out.
 +
* If does not go out with blowing, use the fire-blanket.
 +
* If blanket does not solve the issue use CO2 extinguisher, leave the room, close the door and inform everyone at the lab.
 +
* If the CO2 extinguisher did not solve the issue: call fire brigade, inform the board.

 +
== Start of operation checklist ==
 +
 
 +
* Use keys to turn on power
 +
* Turn on blower (switch)
 +
* If previous operator did not raise the bed to top ask for help from a superuser
 +
* Adjust bed for correct focus distance for your material
 +
 
 +
== Cutting checklist ==
 +
 
 +
* Did you change material ? If yes, re-check focus distance
 +
* Adjust head position, set origin (NOTE: the red helper dot might not be pointing exactly to the cutting point, use "pulse" to verify)
 +
** Make sure you know which point of your cutting job you should set as origin in the machine.
 +
* Use "border view" (sw) or "range" (panel) to verify bounding-box of cut.
 +
* Make sure blower is on (switch)
 +
* Make sure lid is closed
 +
* Start cutting, keep close watch on what is happening.
 +
** Risk of fire
 +
** Settings may need tuning
 +
* When done cutting wait 30-60 seconds for fume extraction before opening lid.
 +
 
 +
== End of operation checklist ==
 +
 
 +
* Remove honeycomb if installed
 +
* Raise bed to top
 +
* Turn off blower (switch)
 +
* Fill operation log (laser on time, work time)
 +
* Turn off machine (keys)

* Clean up the bottom "drop area" in case you dropped something.

** The link to payment info is not here because this page is not limited to members only and asking "the public" for money requires a special permit.
 
*** Check your email or "pinned items" on #yleinen at [[Slack]].
 
** However: If you know a '''business''' that could support us, go ahead and try to get them to buy some of those support items.
 
** Our organisation's own budget is reserved for rent payments and other important operating costs, so we need this special member funding to get this done. The machine is specially reserved for us and is available only for this time for this price and with these specs.

** Why not metal? Short answer: Metal reflects IR too well to be cut with IR laser. Marking metals is possible, though.

* Cutting area 1600 × 900 mm with through feed so full-size stock can be used.

* Total price? About 16k€.
 
** We might also want to order a batch of laser cuttable plywood and other sheet material soon-ish after the delivery + the installation might require some extra work and purchases. Right now we just have some random acrylic mostly in white and orange.
 
* How come delivery is already being prepared when we don't have all the money yet?
 
** 1. '''Optimism'''
 
** 2. The seller is willing to take a risk with it; if we ultimately can't pay they will simply take the machine away again. Oct 12th is not the absolute final deadline but we'd like to be ready early.
 
** 3. We have so far secured a fair amount of the total price as '''external funding''' in this machine, and this money cannot be used for anything else if we don't make it. The price we have to pay ourselves is '''just one quarter of the total''', and we don't want to miss this deal!
 
** 4. It is very unlikely there would be another possibility to get similarly large and powerful machine in this price range with 3/4 of funding already secured. We need to act now and adjust to the seller's wishes to have it delivered.
 
* What happens to my donation in case we ultimately do not make it? For large donations we'll contact and ask whether you want your money back or should we use it for the lab in general (there's always things the we could improve), smaller ones are assumed to be usable for the general good unless you specifically contact the board and ask for your money back.
