This document introduces the compatibility and maximum connection limits between different generations of AMS and printer models, as well as the power requirements for AMS with drying functionality.
¶ AMS 2 Pro / AMS HT Compatibility
 |
 |
¶ H2D Printer
-
Max Connections: Up to 4 AMS 2 Pro + 8 AMS HT simultaneously.
-
Multi-Color Printing:
-
As H2D is a dual-nozzle printer, the most extreme scenario allows connecting all AMS 2 Pro/HT to one nozzle while using an external spool for the other.
-
Max colors: 4 (AMS 2 Pro) × 4 + 8 (AMS HT) × 1 + 1 (external spool) = 25 colors.
-
-
Accessories:
- Built-in buffer (no extra purchase needed).
- For ≥3 AMS connections, a PTFE Adapter is required for "multi-in, single-out" functionality.
¶ X1/P1 Series Printers
-
Max Connections:
-
Up to 4 AMS 2 Pro or 4 AMS HT.
-
Note: AMS/AMS 2 Pro/AMS HT are treated as the same type in X1/P1 Series printers; the total connection limit is 4 units.
-
-
Multi-Color Printing: Up to 16 colors.
-
Accessories:
-
Requires a buffer (purchased separately).
-
For multiple AMS connections, an AMS Hub is needed (purchased separately).
-
-
Firmware Plan:
-
AMS 2 Pro is compatible with X1/P1 printers at launch for feeding filament.
-
In Q2, a firmware update will be released to enable the drying function of AMS 2 Pro and support AMS HT connection/drying.
-
¶ A1 Series Printers
-
Max Connections: Pending (under testing).
-
Accessories:
- Requires an A1-specific buffer (expected Q3 release).
-
Firmware Plan: Compatibility firmware expected in Q3.
¶ Drying Function Requirements
-
H2D + Single AMS 2 Pro:
Can be powered directly by the printer (no extra accessories).
-
H2D + Multiple AMS 2 Pro:
When using multiple units for drying at the same time, only 1 unit can use printer power, and others require dedicated power adapters (sold separately).

-
H2D Power Management:
-
If printing/feeding while drying, drying power is automatically reduced to prioritize printing.
-
Recommendation: Use the power adapter for optimal drying.
-
HMS Alert: "Printer-powered drying detected during printing/feeding. Use a power adapter for best drying effect."
-
-
AMS HT Power:
No matter what model of printer is connected, it always requires 220V external power (which comes with the machine) for drying.
-
X1/P1/A1 + AMS 2 Pro Drying:
Each AMS 2 Pro must use a power adapter for drying.
-
Communication Requirement:
AMS 2 Pro/HT must connect via the 6-pin cable during drying (no offline mode).
-
AMS 2 Pro Drying While Printing Limits:
-
Unsupported Scenarios:
-
AMS 2 Pro is currently in use for printing.
-
AMS 2 Pro has filaments with the auto-refill relationship (even if it's idle for now).
-
-
Supported Scenarios:
- Idle AMS 2 Pro units can dry while the printer is printing (use other AMS or external spool).
-
-
AMS HT Drying While Printing:
-
Supported via firmware update (expected Q2 2025).
-
Note: Drying softens the filament; reliability testing is ongoing to optimize parameters.
-
¶ Legacy AMS Compatibility
¶ H2D Printer
-
Max Connections:
-
Up to 4 AMS or 4 AMS + 8 AMS HT.
-
Note: AMS/AMS 2 Pro share a 4-unit limit; AMS HT has a separate 8-unit limit.
-
-
Accessories: Built-in buffer, no extra purchase needed; PTFE Adapter needed for ≥3 AMS.
-
Firmware: Ensure the printer firmware is updated (new machines will receive firmware push after connecting to the network).
¶ X1/P1 Series Printers
-
Max Connections: Up to 4 AMS (shared limit with AMS 2 Pro/HT).
-
Accessories: Buffer (included) or AMS Hub (for multiple AMS, purchased separately).
¶ A1 Series Printers:
Not compatible.
¶ AMS Lite Compatibility
Exclusive to A1 series printers. Each A1 Series printer can only connect to 1 AMS lite, no plans for other printer models.
