The [Rolland MDX-540] can use proprietary software to cut parts or industry standard programming instructions, know as G-code. G-code specifies initialization parameters then a series of points for the machine to move to at a given feed rate. Although it is possible to write G-code manually, programs like Maste… text/html 2011-01-27T14:46:01-04:00 http://dap.cooper.edu/doku.php?id=classes:designandproto:assignments:electrophoresis_chamber&rev=1296157561&do=diff [ ] Introduction The Cooper Union Open Source Lab has a Universal Laser Systems 6.60 (18”x32”) laser cutter. It can cut through arcylics, wood, ABS, carboard, paper, and many other materials. Lexan and PVC aren't included on this list because they release chlorine gas when they are burned. The laser cutter basically behaves like a printer attached to the computer. Lines over .001” thick and images are interpreted as raster graphics and can be etched on the surface of the material proportio… text/html 2011-01-15T15:29:42-04:00 http://dap.cooper.edu/doku.php?id=classes:designandproto:assignments:lasercutter&rev=1295123382&do=diff Introduction The Cooper Union Open Source Lab has a Universal Laser Systems 6.60 (18”x32”) laser cutter.
