  1. Preserve before install

    Keep 1.1.5 alongside 2.x and retain a reference project because 2.0 was distributed as a separate installation.

  2. First validation after update

    For 2.0.6, retest T1MaxCleanNozzle high-pressure compaction and bulk-device discovery before regular use.

Source review:

Good to know

FLSUN Slicer is FLSUN’s open-source FDM slicer with printer, filament and process profiles for its machines. The 2.x line moved to an OrcaSlicer base and adds FLSUN-specific high-speed and quality tuning.

Sources reviewed:

Where it fits

It is aimed at FLSUN hardware where the vendor’s fast-print profiles, build-volume limits, cooling logic and device monitoring matter more than generic defaults.

Install and update note

FLSUN says version 2.0 cannot be installed as a direct upgrade over 1.1.5; both can coexist. On macOS, rename the 1.1.5 desktop icon first to avoid overwriting it. The latest 2.0.6 GitHub release currently exposes a Windows EXE, so verify the asset list before choosing a platform build.

Menus, folders and commands

  1. Project files

    Where
    Import multi-plate model → adjust each plate → slice
    Contains
    • Multi-plate model · automatic plate recognition
    • Per-plate parameters · slicing
    Check
    Version 2.0.2 imports a multi-color model as the default single color

    Inspect the generated geometry or toolpath before sending it to a printer.

  2. Upgrade boundary

    Where
    FLSUN Slicer 1.1.5 + FLSUN Slicer 2.0 → separate installations
    Contains
    • 1.1.5 · retained installation
    • 2.0 · separate OrcaSlicer-based generation
    Check
    Release 2.0 is not an in-place upgrade of 1.1.5

    Keep an untouched copy before migrating, importing or replacing settings.

  3. Settings scope

    Where
    FLSUN printer preset → process / cooling / machine limits
    Contains
    • High-speed toolpaths · cooling
    • Build limits · printer-specific hardware behaviour
    Check
    2.x presets and behaviour derive from FLSUN's OrcaSlicer-based branch

    Treat these values as printer-, nozzle- and material-specific.

Common questions

Can FLSUN Slicer 2.0.2 handle multi-plate models?

Yes. Version 2.0.2 added multi-plate slicing. When a multi-plate model is imported, the slicer recognizes the plates and adds them for per-plate parameter adjustment and slicing.

Check the source ↗
What happens when a multi-color model is imported?

Version 2.0.2 supports importing multi-color models, but converts their model colors to the default single color during import.

Check the source ↗
Can version 2.0 upgrade version 1.1.5 in place?

No. FLSUN explicitly says to install 2.0 separately; both versions may be used side by side.

Check the source ↗
What changed in the 2.x generation?

FLSUN rebuilt it on OrcaSlicer and added printer-specific work on high-speed paths, cooling, build limits and hardware behavior.

FLSUN 1.x and 2.x

FLSUN’s 2.0 release uses OrcaSlicer and does not upgrade directly from 1.1.5. Keep separate profiles when using both generations.

Project documentation ↗
A quick check before installing
0/3

A project file is not an installer

A .3mf file holds model or project data. Opening it does not install the slicer. After opening a project, check the printer, nozzle and material settings.

Check the official requirements

Files are hosted by the developers. Before installing, check their system requirements and release notes. A file labelled for your platform does not establish the minimum OS version.
