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.
PTFE pipe connection method 6-pin cable connection method -
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.
-
As an application-level 3D printer, X1E needs more time to conduct more thorough testing to ensure the stability and reliability of new functions. Based on the current testing progress, X1E will support AMS 2 Pro and AMS HT drying functions and will be launched OTA in Q3 2025 at the latest.
-
¶ 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).
-
The H2D power adapter supplies 24V 4A.
-
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." (At this point, AMS 2 Pro will dry at 86% of its normal drying power).
-
-
AMS HT Power:
No matter what model of printer is connected, it requires AC:100-240V external power. (which comes with the machine) for drying.
The AMS HT has an average power consumption of 150W when the drying function is enabled.
-
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).
Note: Be sure to use the new 6-pin cable included with AMS 2 Pro and AMS HT. Using the 6-pin cable from the previous generation AMS may cause unstable communication between the AMS and the printer, while the previous generation AMS is compatible with the new 6-pin cable.
-
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.
