How to Slice a Model with Slicer for Prusa
Click through the five steps. Each one shows what you will see in 3DPrinterOS.
Upload Your Model
Add your STL file to the Files page in 3DPrinterOS. Your Prusa needs to be connected first. If it is not, install your 3D printer.
Click Slice and Choose Slicer for Prusa
Click the Slice button next to the STL file and open Slicer for Prusa. The slicers you see depend on your organization.
