I get the error message to remove the filament from the external spool holder. However, I do not have an external spool holder on the printer, only the AMS. I have checked all filament hoses and the print head - all available filament paths are clear. The error message is coming from a phantom - the non-existent external filament spool. I have reset the printer to factory settings. When loading filament from the AMS, the error message came again telling me to remove the filament from the external roll.

There is filament in the PTFE tube to the printhead. The printhead has a sensor at the top input. There is another sensor at the back of the printer that detects whether filament is present.
Either the filament spool was empty or the filament is broken. You need to remove the filament from the bowden from the printhead to the back of the printer.
Have a nice day!
Es befindet sich Filament im PTFE-Schlauch zum Druckkopf. Der Druckkopf hat am Eingang oben einen Sensor. Hinten am Drucker ist noch ein Sensor, der erkennt ob Filament vorhanden ist.
Entweder war die Filamentspule leer oder das Filament ist gebrochen. Sie müssen das Filament aus dem Bowden vom Druckkopf zum hinteren Teil des Druckers entfernen.
Schönen Tag!

Hi,
It seems something went wrong when I tried to unload the filament in one of the slots (#3 probably doesn’t matter here). I was using a SANMATE TEMP Color Change filament 1kg original spool (not re-spooled to Bambulab) and it got stuck during the unloading process. I had to disconnect the AMS unit, bowden tubing, cables etc. and then pull the filament out by force, not cool. Is there perhaps a weight limit for the AMS transport mechanism and what is it? It certainly seems to have problems with a 1kg loaded spool. So what is the weight limit? 0.5kg?
Best Regards
Es gibt keine Schwierigkeiten mit 1kg-Spulen. Ich setze selbst dauernd welche dort rein.
There are no difficulties with 1kg coils. I put them in there all the time myself.
Thanks ‘Coffee pot’ or should I say ‘pot coffee’ 
I checked the ‘rims’ of the spool and found a couple of rough spots. It seemed like a solid plastic spool otherwise. I filed/sanded them down and the spool turn now better in the rollers. We will see. I guess using a non-BambuLab spool is a bit of a gamble. I will try to get a re-spooler or use a Y-splitter in the back to use OEM filaments/spools that give me trouble on the back hanger,
Tschuess und vielen Dank nochmals,
Klaus in den USA
Ich hatte einmaleine Spule, da waren die Kanten etwas rund. Habe Klebeband außen drauf geklebt, funktionierte gut.
Tschüß Klausi
Guter Vorschlag!
Perhaps a grommet edging/liner type (U profile) printed in TPE would work and also would increase the roller ‘grip’ and also dampen vibration I have noticed. It could be re-used from spool to spool. Grommet edging is also available commercially but it seems only in Polyethylene which is more rigid and slippery. We’ll see what I decide on.
Danke.
same things happenning to me whats wrong?
