So I finally ran down my first full spool of BL brand filament and had a 2nd identical roll in the AMS and the auto-refill option on in Studio. I assumed this meant I could walk away and it would run out the main spool and then auto load the backup.
BUT… the spools from BL (and maybe all companies) are TIED to the roll. Meaning, the printer can never empty a roll on its own. It gets to the end and struggles for a while before throwing a motor error on the printer and pausing for a human to cut the end with scissors.
Yes, once you manually cut the filament it then DOES auto refill but seems sort of odd that we have this amazing tech and feature for big prints that could be automated if only the spools weren’t tied when they were wound up at the factory. Certainly there is a better solution?
I haven’t seen a Bambu spool with a tied off end yet, but then I’ve only finished 3 or 4 that I can remember. Hopefully yours was a one off and not the norm. I have run dozens of spools from Overture empty and not a single one was tied but I remember one having a sharp bend that I didn’t like. I was able to cut it off by reaching through the center hole.
BBL filament definitely pulls all the way through (not tied). Sometimes they are kinked too much and don’t feed well, but the option works very well 90%+ of the time.
I’ve been through about 10 spools of BBL filament.
Good to know, thanks! But, strange, because I’m using BL brand normal white PLA and it was VERY much tied at the end of the spool. I hope it was just a one off situation then.
