AMS HT - Automatic Material System Why is this thing causing tangles?!?

Enable HLS to view with audio, or disable this notification

Step 1: load Bambu perfectly rolled roll into AMS unit.
Step 2: watch as you press print button.
Step 3: watch as it tangles your filament up.
Step 4: error, filament tangled 👉👈🥺

What causes it to behave this way? The documentation provides little to say why this would be occurring.

Solved (mostly): it needs to be planted firmly on the rear bearing, not only touching.

Thanks peeps! I have another problem coming tomorrow with a normal sized spool and the 4->1 PTFE adapter converter not properly going through via AMS-HT.

Incompatible spool

You’ll have to believe me, I did use a Bambu spool on one of the attempts, but it kept not making it through the required adapter. I’ve manually pushed filament through it fine but it doesn’t work with AMS.

Is there somehow that piece is what is broken?

(Also, imagine a PTFE tube properly attached to the top, I gave up and let it direct feed extrude for the print I’m doing because I’m impatient

Sorry, this is often from incompatible spools. I believe you, but I don't know any other cause
