Hi George. I don't have a real good place for my laser for exhaust to the outside so I have a switch that turns on the air pump and the vacuum just before I set it to burn. I follow the head with my vacuum to get up as much of the smoke as I can and so far it does a good job. I plan to make a hood for it with the vacuum attached and that flips up. I have been out with heart surgery so everything got put on hold for a while. I'm just getting to make stuff again.
I looked for 3 years for a laser and decided on this X Tool lase because my neighbor in Arizona bought one and did some jobs for me with it. I did not think I could learn how to run it but I did and it is quite easy now. It will do 100 times what I use if for but I'm not a teckie...my motto is the KISS principle. The XCS software that comes with it is very user friendly. I sent an EBay link above to a reconditioned one like I have- saves you Hundreds.
