Job Files

.gjob files store everything that a printer needs to print a Continuous Print job.

Why create a new file type?

3D print slicers generate a *.gcode file for a particular make and model of 3D printer - running that file on a different printer than the one for which it was sliced would likely damage that printer (or maybe just fail to print properly).

Similarly, GCODE doesn't allow for quickly changing the number and type of objects which are printed - which is something Continuous Print does as a base feature.

Other metadata (like material types and printer profile supported by the GCODE file) are also non-standard and stored in a slicer-specific way, if at all.

For these reasons, it becomes useful to define the .gjob file type.

Creating a .gjob file

1. Click the check box next to one or more Jobs in the Queues tab to select them.
2. Click the save (floppy disk) icon that appears at the top of the queue to save to .gjob.

All saved .gjob files will appear in the Files panel on the left.

Loading a .gjob file

To load a .gjob file, click the + button next to a .gjob file in the Files panel.

The job will be inserted at the bottom of the queue in an edit mode - make any desired changes, then hit Save.

Technical Details

Under the hood, a .gjob is really just a .zip file containing the various .gcode files, plus a manifest.json file which describes how to print them.
