FAQ
1.What is the difference between the two discharge ports on the back of the machine?
 

The port at the rear of the top cover is specifically for TPU filament. Due to the softness of the TPU filament, it is easy to fail when using the AMS 2 Pro automatic feeding function. When using the TPU, insert it into the AMS HT and ensure the material tray rotates in the correct direction. Insert the material tube into the TPU output port and manually push the filament through the PTFE tube until it is fully loaded into the extruder.

Note: When using TPU, AMS HT cannot use the automatic feed and return function, but can be used as a drying box to prevent material moisture.

2.Can the AMS HT be used with the X series and P series printers?
 

MS HT compatibility with X1 and P1 printers will be added through an OTA update by the end of April.

If only connecting one AMS HT to a X or P series printer, a filament buffer is required to be purchased separately. If connecting multiple AMS HT units,we recommend that you purchase an AMS Hub.

AMS HT compatibility with A1 and A1 mini printers will be added through an OTA update in Q3 2025.

3.Can I print and dry at the same time?
 

Printing while drying is not yet supported, including all the AMSs that are related to the on-going print job (eg. The AMSs assigned for auto-refill). However, you can dry filament in AMSs that are not assigned to the on-going print job.

4.How many AMS HT units can be connected to the X1 series and P1 series at most?
 

X1 and P1 series printers support up to 4 AMS HT connections at the same time.

5.Can the AMS HT be directly connected to the printer for drying?
 

H2D and X/P/A series printers are connected to AMS HT and use drying function. Each AMS HT requires an external 220V power supply for drying It is not supported to draw power from the printer for drying (The power adapter is pre-included with the product package).

6.Does it support standalone drying without connecting to the printer?
 

When using the AMS HT drying function, the AMS HT must be connected to the printer via a 6-pin bus cable to ensure that the printer is powered on and set to filament drying mode.

The AMS HT cannot perform standalone drying without a connection to the printer.
