Laser cutters

This may be a shot in the dark, but I need to seek advice in a woman-friendly space. I need to learn how to use a laser cutter. The model in question is a Rabbit QX-1290, if that means anything to anyone. I have access to one and I know it has potential for cutting Tyvek and leather, and I hear even fabric, and I think it could be amazing, but no one knows how to use it. My coworkers have spent the last month using it to cut tiny discs out of huge sheets of plywood and they keep saying they'll teach me how to use it once they figure it out. I don't think we've even defined a work flow for making things with it, like how do you create a file that the thing can cut, and import that file into the driver software, set and load the machine, and make it happen.
