Included catalogue

Mosso Slicer intentionally exposes only:

• WASP 3MT HDP XL with 2, 3, and 5 mm nozzles.
• WASP 4070 with 0.4, 0.8, and 1 mm nozzles.
• WASP 60100 HDP with 1 and 2 mm nozzles.
• Polymaker PETG 20GF - Copy, Generic PLA, and Generic PETG.

The 3MT profile includes its 1000 mm diameter by 1000 mm cylindrical volume, front exclusion area, two heater zones, Firecap command, purge routine, and OctoPrint address. The API key remains a per-user secret and is not stored in this repository or installer.

Expert settings are always visible, the first-run setup wizard is skipped, thumbnails are disabled, and Orca/Bambu account, cloud-storage, cloud-preset, and cloud-plugin services are disabled. Projects and presets remain on the local computer.

These are controlled test profiles. Review generated G-code and validate the 4070 and 60100 heater/start/end sequences on the exact controllers before production use.

Running a local Windows build

After building and installing locally, run:

& "C:\Users\Acer Nitro\Documents\ChatGPT\UPMSlicer\build\MossoSlicer\mosso-slicer.exe"

Mosso Slicer stores its settings separately from OrcaSlicer in %APPDATA%\MossoSlicer.

Building on Windows

Use Visual Studio 2026 with the Desktop development with C++ workload, CMake, and Git. In Developer PowerShell for Visual Studio:

cd "C:\Users\Acer Nitro\Documents\ChatGPT\UPMSlicer"
.\build_release_vs2026.bat

To rebuild only the slicer after its dependencies are available:

.\build_release_vs2026.bat slicer

The installed build is placed in build\MossoSlicer. To create a shareable installer after a successful build:

cd "C:\Users\Acer Nitro\Documents\ChatGPT\UPMSlicer"
cmake --build build --config Release --target package

The generated file is named MossoSlicer_Windows_Installer_V<version>_x64.exe in the build folder.
