S5 Display shows PLA empty but it´s not?!

[hodey 0]

Dear makers of the Ultiworld,

 

I got a problem with my PLA? Or print core of the Ultimaker S5?

I am using a regular PLA which is printable between 180-220 degree.
However, the printer is printing some layers and than, the display

shows:

 

"Material seems to be empty. Please switch the material to continue with the job"

something like that (it is German, see pictures below). But is NOT emtpy.

 

Do you have an idea what went wrong? what can I do? I though to put somekind
of a clip incl. oil on the back of the filament. So the material is oiled and can flow
better into the print core.

I had that problem a lot when printing complex TPU parts. The simplest workaround would be to just disable the flow sensor, which is not ideal, but worked for me.

 

But before you do that, check if there are other problems that could have caused the issue, such as the feeder grinding the material and/or a tangled spool.

 

I would avoid putting anything onto the filament, that could cause all kinds of issues, from layer separation to burned oil residue in the hot end.

When you checked everything and didn't find anything wrong you can assume it was a false alert. Maybe you want to stay with the printer for a minute in order to make sure it does not throw another false alert a few seconds later.
