The Repetier-Host is a simple to use host software, which is be compatible with most firmwares around. You can add and position your STL files on the simulated printbed and slice them all together. For slicing you can use the built-in Slic3r slicer or use the well-known Skeinforge. Just call "Slice & Load" and the job gets delegated to the current slicer, showing its output in the log window.

Slic3r' is free software 3D slicing engine for 3D printers. It generates G-code from 3D CAD files (STL or OBJ). Once finished, an appropriate G-code file for the production of the 3D modeled part or object is sent to the 3D printer for the manufacturing of a physical object. As of 2013, about half of the 3D printers tested by Make Magazine supported slic3r.

FlatCAM is a program for preparing CNC jobs for making PCBs on a CNC router. Among other things, it can take a Gerber file generated by your favorite PCB CAD program, and create G-Code for Isolation routing. But there’s more. See the features list below.
