- Open Simplify3D, preferably with an existing .factory file (the one attached here is a good starting point, but you should make your own for materials you have loaded).
- Import your STL, "Prepare to Print!", "Save Toolpaths to Disk" to generate the toolpath file (gcode).
- The Diabase Wizard will open. Click through everything.
- Upload the file to the H4 machine via a web browser.
Then click on the file to start printing.
