This guide provides instructions and precautions for replacing the AMS Lite filament funnel unit. The purpose is to disassemble the filament funnel unit to check whether the gear rotates smoothly.
Since the upper and lower filament funnel unit on both sides are similar in structure, this article only replaces the AMS lite filament funnel unit (3) and explains some precautions.
The filament sensor of the feeder unit cannot detect the filaments correctly. For example, the indicator light does not respond after the filaments are loaded. The filament funnel unit needs to be replaced.
The feeder unit is difficult to load. It is suspected that the gears are not rotating smoothly. The filament funnel unit needs to be removed for inspection.
It's crucial to disconnet the AMS Lite from the printer before performing any maintenance work on the AMS Lite and its electronics, because leaving the AMS Lite connected while conducting such tasks can cause a short circuit, which can lead to additional electronic damage and safety hazards.

Align the funnel with the buckle and install the pin from the opposite side; hold the knurled side with your hand, insert the non-knurled side first, and then press the pin in firmly.
Align the gear with the buckle and place it. Check whether it is in place by looking at the gaps between the buckles on both sides. Hold the knurled side of the pin with your hand and install the pin from the buckle, making sure the non-knurled side is inserted first.
1. Connect the cable; adjust the position of the swing gear set as shown in the figure, with the outer gear pushed to the left and the inner gear standing up.
2. Install the filament funnel unit and use an Allen key to insert the other end of the spring into the indicated hole, ensuring that the spring is properly installed.
Note that the outer swing gear is under the limit block.
A similar operation can be used to install the AMS Filament Funnel Unit-Left. However, you need to pay attention to the installation position of the gear sets. This installation position is somewhat different from the AMS Filament Funnel Unit-Right. Please see the picture below for details.
