'''Warning:''' you cannot use the "touch off" feature of EMC with a Graster job, it will not work and bad stuff will probably happen. ''Before starting a job, make sure the coordinate system is reset by going to'' Machine -> Zero Coordinate System -> P1 ''(the first option)''. | '''Warning:''' you cannot use the "touch off" feature of EMC with a Graster job, it will not work and bad stuff will probably happen.

Graster is already installed on the laser PC | Graster is already installed on the laser PC you should use it there, if possible, because it is still a bit tricky to install. | ||
To use it: | |||
# Load the image onto the laser printer.<br/><pre>scp image.png hacklab@laser.hacklab.to/image.png</pre> | |||
# SSH into the laser printer. | |||
# Run the script on your image.<br/><pre>../graster/graster.rb image.png</pre> | |||
# The output results in three files: <br/> image.png.cut.ngc - A box cutout of the image. <br/> image.png.raster.gmask - The gmask file with laser instructions.<br/> '''image.png.raster.ngc''' - This is the main Gcode file that you want to load into the cutter. | |||

To run Graster yourself, '''you will need Ruby 1.9, not Ruby 1.8'''. At present, the version of 1.9 in the Debian/Ubuntu repository is '''very old''', do not install it. You will have to build Ruby 1.9 (or later) from source (http://www.ruby-lang.org/en/downloads/). You will also need to install RubyGems and a gem called rmagick (which is used to read image files). This is all a bit of a hassle and a simpler install method is planned for ''The Future''. | To run Graster yourself, '''you will need Ruby 1.9, not Ruby 1.8'''.

The image can be any common format.. PNG is probably best. A job can be configured with command line options or a configuration file. You can generate a default config file with the -g option.
