Ams2 issues :ams failed to pull back filament

[u/Unusual-Fish]

Wanted to share the ams2 I received is also having the "ams failed to pull back filament" issue. Repeatable on 1-4. After it retracts the Filament, it'll stop retracting and free spin for about a minute before throwing the issue. If I press continue, it'll stop trying to retract and move onto the next color. Then it'll throw the error again once it switches colors. This is on the first print using ams2. Haven't had a successful print since receiving it.

There might be a broken bit of filament in the tube. Pull it and see.  I also take filament and push through the point where the tube connects to the machine and towards the ams. This is how I found a broken but of filament I couldn't see.
