sorry for forking the email thread (some of you are getting this twice):
safety training for the laser, any material not specifically made
for laser cutters (the stuff in the pile next to it) needs a flame test
first.
never cut pvc, never cut fluffy flammable things etc. make a small cut first.
Beyond the safety critical things here's some personal thoughts on laser etiquette:
-4:
if you see someone looking lost and poking at the laser, come help them
to understand community expectations and how to use it safely.
-3: Care about those around you, both their comfort needs and their futur'ish'build'cool'stuff needs.
-2: if you are uncomfortable say "hey, can you use do that after <time / i finish-x>,
-1: if someone in the room is uncomfortable, cut later. Almost no projects need to be cut now!
0: leave the lid closed for 30 seconds after the cut finishes to give the smoke time to clear.
1: don't use the machine if there's an event happening, the blower is loud.
2. check the chiller temp each time you hit start
3. turn the laser enable switch to the off position when you are not cutting.
4:
if you mangle a part because some settings don't work, label your part
with the settings and display it for others to learn from. eg: 1mm/sec
is too slow and makes really ugly looking edges at 80% power.
Community norms take time and compassion to develop,
