This morning I was printing with a spool that was close to running out, no big deal, I already had a bambu spool refill. When the spool ran out, the printer stopped (as expected) I pulled the spool out (I don’t have any empties), loaded a refill onto that spool, ensure it was seated properly, etc and tried to feed the filament into the AMS. However, the AMS would not grab the filament and wouldn’t do anything but flash the slot. I know the slot is empty, but it won’t take the filament. When I checked the screen, it was showing a diagram as if it was expecing me to manually feed it to the extruder as if it was an external spool. I tried many times but could not get the AMS to feed. Finally, I just stopped the print (luckily, only a 2 hr print). I then tried to load filament again and the AMS pulled the filament as usual and the RFID identified it as usual. I’m pretty new to 3d printing and this printer, but I did a lot of reading on what to do to replace a spool midprint and it seems like I was doing what I should, but my AMS wouldn’t take the new filament and resume the print. I’d like to determine root cause because if this occurs on a larger print, I could have issues. I realize I can always buy a duplicate spool but, in many cases, I’m using multiple colors and it’s not always feasible to have a refill backup loaded.
I know its long, but in short, what should I have done to get this to load and resume?
i just had the exact same thing happening! i was used to just do the loading, but indeed it does not pull the new roll in, clearly a bug, as that was always the behaviour in the past
Thanks, I was very frustrated with it. I kept thinking, this can’t be “rocket science”. I pulled the roll out of the slot, put it back in, it just would not load the filament. @SupportAssistant we have a bug here.
I tried. I put new filament in, press resume, then it said “AMS didn’t feed filament” (even tho it was loaded and ready), then it showed the “loading filament” screen with the graphic wanting me to push it all the way to the extruder as if it was loaded externally so not sure.
Perhaps that was my mistake then, I assumed it would grab the filament as it always does at the AMS. I’m still researching this but if this is expected, then maybe it’s not a bug it’s a design choice.
This is how mine behaved last time it happened. It would run out, I then pull that roll out of the AMS and insert a new one. It would grab it right away and then load the extruder. I definitely did not have to push it all the way to the tool head. That was a couple firmware revisions ago.
