Ortur Laser Master 2
I got one of those Ortur Laser Master 2, laser engraving machines. This is not really a review of the machine but suffice to say that I think it is awesome.
It is not the end all, be all machine for laser engraving for sure but it is WAY more than enough for most hobbyists. Also it will do things that technically it isn’t supposed to do thanks to the ingenuity of community of people behind it.
Rather this post is about adding Air Assist to the laser. In short if material is too thick to cut and takes many passes an air assist system will speed things up and produce much cleaner cuts free of smoke and burning. In the picture below you can see evidence of burns in the lines and especially where the lines are close like in the “E” and the top of the logo.
Slight burning marks on logo and prominent on “E”
Here is the exact same cut, using the exact same settings, with Air Assist in the pic below.
