As with the original AMS, the angle of the filamnet going into the extruders is a little harsh which can result in feeding and retraction issues, including motor assist overload failures.

*SECOND PROFILE ADDED*

Includes two stripes on the thumb press area for a touch of extra customisation. 

This simple modification aims to combat that, and installs very simply, and is easily removable for maintenence.

Cut PTFE to your preferred size, and install into the AMS 2 PRO PTFE Guide mod hole (It is a tight fit to ensure it doesn't get pulled out of the fitting during operation of the AMS)

Simply snap the PTFE Guide mod in place, over the top of your extruder feeders.

Larger, curved, surface area for the thumb press. 

I model from a position of homelessness, so all support is very much appreciated.
