  Bart from wrote in to share his latest DIY laser cutter
design, the 2.X laser. The mechanical parts are all either off-
the-shelf or lasercut, and it can be controlled using a number
of standard electronics sets. Oh, and did we mention it’s all
available with a Creative Commons license?  The second
generation open source laser cutter/engraver design from is
complete. The new machine is called the 2.x Laser. The name
comes from the fact that this is the second generation machine
and it is basically a 2 axis design. The third, vertical axis,
is manually controlled with an optional upgrade to digital
control. The 2.x Laser takes all the optimizations learned from
the first laser and all the other lasers documented on forum.
The usable work envelope is 12” x 20” x 4”. The internal design
has been optimized so the overall size of the machine is much
smaller than the previous design and can easily fit on a small
table. It is designed to work with 40W CO2 lasers sealed gas
lasers. The frame is built from inexpensiv
