Anyone have any idea why my two AMS’s I have won’t feed filament if the PTFE tubing is more than 50cm long?
I need it to be at least double that
Its not the printer as I have just replaced my P1S with a X1C
regards
Not 100% sure:
Once they were rewinding endlessly. But I remember a unboxing video I saw, were they don`t conect the PTFE tube to the Printer. The AMS was Stoping on a point so it do not feed the whole spool…
So there is may now some security point in that the entire coil will not be unwound if the PTFE breaks. I have no idea at how many meters and if it is really in.
Are you using the filament buffer that came with the AMS or the AMS Hub?
i’m using the 4 port AMS Hub I got from bambu lab website
Well that is a problem. With the hub the AMS is supposed to feed filament at whatever length is needed to reach the print head. For some reason I think it’s not registering that the hub is in use and not the buffer.
the printer knows the hub is there as it feed from both AMS’s during the same print
I think you can set a distance range in Studio in the printer sertings. But keep in mind that friction may prevent a meaningful extension. I tried last year to extend the distance but the motor couls no longer feed all the way to the extruder.
Do you where in bambu lab the setting is, I can’t find anything about the length of the PTFE tubes
Not at the laptop atm. I think there’s a field in the printer settings where you have Start- & End-gcode but on a different tab. I may wrong though. Sorry for not being able to give more specific directions atm.
ok thx, will look into it

Sorry, I need to correct my mistake. There’s only a filament load and unload time for the time prediction statistics rather than length that I could find.
Having renewed the PTFE’s over the weekend, I have found that the AMS will feed between 1 and 2m of filament before stopping if not stopped though (by for example triggering the extruder switch). From past experience, that length will not be achieved if running insides a PTFE across bends though.
that’s something I’ll look at in as I’ve got my AMS’s on the left hand side of my X1C
Same here. That allowed me to make a rather short path for one of my 2 AMS. Still need the long path for the second one as I need to move that for loading. It works though. Just not happy with the free floating Hub in my config.
