The AMS 2 Pro is compatible withP2/X1/P1/A1 series printerswith extra accessories needed. Please make sure to select corresponding accessories in the add-on section according to your use case.
For P2/X1/P1 owners, a switching adapter is needed to power the drying function. Since filament drying lasts long, you rarely need multiple adapters running simultaneously. The optional adapter helps lower the price.
For H2D owners,your H2D can power anyone of the AMS 2 Pro(s) connected for drying, so if you're not planning to run multiple AMS 2 Pro for drying simultaneously, you won't be needing an adapter.
For X1E owners, the AMS 2 Pro drying feature is currently under testing and not yet supported.
