UM Material Station not winding up the filament spool when retracting

[B_Roll 0]

Hi everybody,

After the last few prints, the Material Station fails to wind up material on their spools when it retracts the filament from the printer, so after every print there's huge pile of spaghetti in the Material station. I've rebootet the whole system several times and also updated to the latest firmware(6.5 I believe) and the latest Cura(4.10).

 

Any idea what to do next?

1. is the rewinder motor running during the moment of unloading? it is reasonably loud so you should be able to hear it.
2. are the lights on on the bottom of the machine after reboot, do they change when you insert filament?
3. Are these normal spools?
   Ive had problems rewinding some non ultimaker spools before since they didn't fit well enough and the grip didn't transfer enough (cardboard spools in my case)

if you are familiar with telnet I could give instructions on testing the rewinder motor directly.

If the motor isn't running at all, the lights are responsive and these are normal spools I'd say contact support here it sounds like it could be a hardware problem.

Side note, I recall there is or was a bug where rewinding is blocked if you insert new filament right when it should start the rewinding, but that seems unlikely if it happened multiple times.

Hi and thanks for your help.

It is quite difficult for me to distinguish the motor sound, because on the other side of the wall where the printer is situated, there is the production line so there is always quite an ambient noise from the machines. 

There is a motor sound when it is retracting, but I guess it's from the filament drive in the front of the station, right where the filament goes in. The rubber barrel where the spool sits on in the back is not turning.

 

The lights are on after reboot

 

All of the spools are Ultimaker spools except one, which is Ultrafuse PAHT CF 15. However, the spool looks just the same except the RFID tag missing.

 

I  used Telnet before, but it's been a long time and also I don't know if our company network will let it through...

Hi,

Any luck with this one?

We've been having the same issue

If your material station is not properly rewinding the spools.. 
I would recommend reaching out to UltiMaker Support directly as UltiMaker does not provide formal support via the community.
