Filament Presets

Issue: BambuStudio matches filament presets to printers by checking whether the full printer preset name (e.g. "Bambu Lab X1 Carbon 0.4 nozzle") appears inside the preset's name field. Polymaker source files use the abbreviation @BBL X1, so the substring check fails and AMS slot temperature / type do not populate when assigning the imported filament.

Solution: This website now automatically splits BambuStudio downloads into per-printer files and rewrites the name field to contain the full printer preset name. Download presets using the JSON or .bbsflmt buttons on this page — do not copy raw JSON files directly from GitHub.

Issue: P2S printer may overheat when printing materials with vitrification temperature > 50°C due to starting G-code issues.

Solution: We have implemented a temporary fix by adding cooling G-code commands to P2S presets with vitrification temperature > 50°C. This is a temporary workaround until Bambu Lab fixes this issue.

Thanks to alexbreinig and capsel22 for identifying this issue.

Issue: BambuStudio may not correctly apply newly imported filament presets until the application is restarted. Slicing or printing without restarting may use incorrect temperature, flow rate, or other filament settings.

Solution: Always restart BambuStudio after importing Polymaker presets, before you start slicing or printing. A warning popup will also remind you when downloading BambuStudio presets from this page.
