## Settings

### Meta

Default is empty.
The 'Meta' field is to add meta tags or a note to all your files. Whatever is in that field will be added in a meta tagged line to the output.

### Name of Alteration Files

Preface looks for alteration files in the alterations folder in the .skeinforge folder in the home directory. Preface does not care if the text file names are capitalized, but some file systems do not handle file name cases properly, so to be on the safe side you should give them lower case names. If it doesn't find the file it then looks in the alterations folder in the skeinforge_plugins folder. If it doesn't find anything there it looks in the craft_plugins folder.

#### Name of End File

Default is start.gcode.
If there is a file with the name of the "Name of Start File" setting, it will be added to the very beginning of the gcode.

#### Name of Start File

Default is end.gcode.
If there is a file with the name of the "Name of Start File" setting, it will be added to the very end.

### Set Positioning to Absolute

Default is on.
When selected, preface will add the G90 command to set positioning to absolute.

### Set Units to Millimeters

Default is on.
When selected, preface will add the G21 command to set the units to millimeters.

### Start at Home

Default is off.
When selected, the G28 go to home gcode will be added at the beginning of the file.

### Turn Extruder Off

#### Turn Extruder Off at Shut Down

Default is on.
When selected, the M103 turn extruder off gcode will be added at the end of the file.

#### Turn Extruder Off at Start Up

Default is on.
When selected, the M103 turn extruder off gcode will be added at the beginning of the file.
