Bambu spools are GARBAGE

I am NOT going through the support ticket process. Your POS spool came apart in the AMS. You owe me a new spool of Dark Blue Matte, immediately. Or I will NEVER buy filament from you again.

Calm down. Take a deep breath.

Sorry you lost a roll of filament.

But to keep this from happening again you need to print some desiccant containers that go in the hole of your spools. It gives you two good results. One is when you tighten the desiccant it wont let the spool halves come apart. Two is gives weight to your spools in the AMS. That keeps your spools from jumping around in the AMS.

If you decide not to do any of this at least make sure the spool halves make a locking click whether you bought the spools or bought a refill. Its very important you check this. Or you will get the same results.

You might want to print and keep a few of the spacing shim around. I don’t know why they don’t ship with the spool. Here are the instructions for it’s use.

Thanks for the info. I’ll definitely consider it.

But I don’t think I should “need” to print anything to make up for Bambu’s terrible engineering. If THEY want to print Band-Aids and include with the filament as an apology for being stupid, then I would use them. Cautiously.

Not really, maybe a little time to respool onto a new spool. I’ve had to do it solely because of my mistake of printing a spool in PLA that deformed and let go. It takes a little time but isn’t hard with one of the many repooling jigs. The one I used was simple and fit into a drill chuck. Took about 15 mins to respool.

A pretty new spool came apart on me in the AMS too. Only happened once and I respooled. Annoying and time consuming but not the end of the world.

Now, I check the locking on every Bambu spool and have a collection of the locking shims printed too. Never had another issue.

Using the shims will prevent the spools faling apart.

OK, My intrest is piqued.

So I’m trying to picture how a spool came apart. There’s a twisting motion to unlock the spool, then it needs to be twisted again, each side spinning opposite each other until the cams reach the end and they can be pulled apart.

Was this spooled from the factory? Was it a refill?

Do you remember anything about it when you unpacked the spool if it wasn’t a refill? Did the sides look a uniform distance apart? Did it feel funny, like squishy when you pulled it out and put it in the AMS?

If it was a refill did you use a official bambu spool or a printed one? How did you put the refill onto the spool? Do you remember it locking, or feel that “click” at the end of travel?

Did you look at the spool when it came apart? Was there any loose plastic in the slot the spool came out of?

I am not blaming you. Just trying to understand what happened.
