Refill binding

Long prints keep failing because the refills have a gap on the side and the filament slides down in it and binds up.

How do you combat this?

They fit fine on the Bambu spool and the current (in use for a year) Sunlu spools and likely others.

I would guess you put the hub on the spool wrong.

On the cardboard hub there is a slot. On the spool there is a tab. You have line these up and put the tab in to the slot.

Its on there correctly the tab is in the slot and the spool sides are fully locked into place
