I feel like I need a very loud beeping alarm that tells me my AMS PTFE is NOT connected to the printer, I’ve left it disconnected probably 10 times so far, and we know what happens.
So far it’s only happened when I was (luckily) in the same room or the next room, so I’ve only gotten a few meters of filament everywhere, but I was wondering, how long will it run for before it times out, or will it just unwind the whole spool?
You’d think bambu would have a sanity check/ timeout at say maybe 1m of filament unspooled before it says “ok it definitely should have made it from the buffer to the extruder by now”
I assume you have an A series with an AMS lite.
I often do this when swapping between the AMS lite on my A1 mini and the external spool.
I don’t do it on my P1S printers as I have yet to actually use an external spool on any of them.
When I do, I will finally attach one of these o bought.
It will unwind the full spool if you let it… Ask me now I know… This just recently happened to me. I wish I had taken a picture of 3/4 of a spool of black abs unspooled inside a P1S. I forgot to properly reconnect the print head PTFE tube.

X1C and P1S with AMS, my A1 Mini does not have AMS yet.
Edit to add, I did initially have a Y fitting on the PTFE from the AMS so I wouldn’t have to disconnect, but that Y fitting pushed the resistance value over the edge of what the AMS could handle and it would’t feed/retract properly with it installed. I might try and re-route my PTFE lines coming from the AMS’s to be able to run the Y fitting again so I can not worry about reconnecting after using the external spool.
That’s crazy there is no timeout at all!
I’m pretty sure there is on filament load in but there isn’t while printing.
