BB 0.4 Core won't unload or eject


Recommended Posts

Posted · BB 0.4 Core won't unload or eject

Printer: Ultimaker S5

Issue:

 

After running the cleaning option I was able to unclog the AA 0.4 core in slot 1. But the BB 0.4 core in slot 2, which has PVA loaded, will not unload, and therefore cannot be removed, and also is preventing any printing. When we try to disable core 2 in Cura and just print with core 1, PLA via AA 0.4, it still says that core 2 is overheating.

 

We might not be able to get this serviced for several days to a week, so we're looking for a way to at least get the filament out and the core out. Our hope is to then just use our two AA cores to print with no PVA. If we pull the tube and cut the filament, can we pull out the core without heating it and initiating a core change int he software? Can it be pulled 100% manually?

 

Additionally, we have only used the BB 0.4 core twice, and both times it failed. So we have not yet had a single PVA-supported print since buying the printer 1 month ago. The nozzle tip on the BB 0.4 also appears charred, after 2 uses, both of which failed within 10-20 minutes of starting. So this core has barely been used.

 

Any tips would be greatly appreciated. Thanks!
