Hello @lasertechs I’m having a problem here. I’m trying to cut some plywood 6mm. Save exact settings I used before Christmas and same exact birch plywood from kitronik (laser grade). Cut this material several times before on this machine with the same settings and never had any problems!
Any ideas why this is happening?
Also, the laser had has gone a bit dark because of the flame, is there anything I should do?
Many thanks,
Michele
I found out what it was. Somehow the panels shipped with lots of wood dust on them. That was what cought fire.

Ensure settings in the dialogue box when you click ‘print’ in coreldraw (or equivalent) are what you need. Go to “properties” and check settings are correct for your use. Then click “print” which will launch tool control - again check settings are correct
Ideally we need a proper functioning air compressor (@directors) in the space to clean machines down and as in this case materials
I believe we scavenged one recently?
@joeatkin2 will know more
There’s a huge compressor in the wood shop by the main bench isn’t there ?

Yeah, there’s a whole bunch of hose on a self retracting reel somewhere as well. Neither of the compressors in the space are quiet though (or necc work).
Are they both too loud to have in the snug and pipe the air through in semi-ridged pipe ?
Courty
A question which I believe can only be answered empirically 
It can only make 6 bar but that should be enough
FYI in case it’s not obvious don’t blow air into or anywhere near the laser cutter because the dust will settle on the mirrors and lenses which are deep inside the machine and are usually protected from dust.
