Suggestions for an heavy duty open design laser cutter

Postby zippys123 » Sun Apr 07, 2013 10:39 am

Hi guys,

need an laser cutter (open source) like buildlog, but something more rugged and heavy duty (to cut acrylic enclosure cases and raster on anodized aluminum)
-square hollow steel tube skeleton
-outer body of sheet metal
-powder coated body
-60 watt co2 laser tube(later upgradeable to 80-100 watt)
-LAOS main control board or lightobject DSP
no specific plans on bed size as of now

i have seen quite a good google sketch up of an laser cutter rendering here in buildlog.net quite a while back but i am not finding now.
please give your suggestions all are welcome :D

You might be able to stretch a 2.X along the X-axis.
This would allow more room for a longer laser tube.

You will get more accurate advice if you post your proposed X, Y and Z requirements.

Here is a link to a program that will scale up the 2.x BOM to larger sizes:
