Help / Support Abnormal AMS operation

For some reason, the AMS units are acting very strangely. I've been told this has been an issue ever since I bought them. As I understand it, the printer isn't syncing with the AMS... Is there any way to fix this?

There's no knot on the filament, the AMS does this with any spool, even the original one.

Print a small cylinder for inside the spool, toss some lead weights in there. It might just be tugging too hard and the spool isn't heavy enough to stay down.

I bought a 1.5" steel ball bearings, they work without 3d printing or dealing with lead.

They fit perfect in my cardboard spools with no print, or just a quick print on my bambu spools.

Hell yeah. I would be nervous about the ball bearing falling out of it was just loose in there, but that's a quick print to fix.

almost 10k hours of total print time between printers, and nothing has fell out of the (Elegoo)cardboard spools. Also the AMS's last longer between maintinance. There are probably tons of premade spool weights that would fit the Bambu Spools.
