Underextrusion with 1.5 Layer

Recommended Posts

Posted · Underextrusion with 1.5 Layer

Hi, the feeder of my UM2 makes this horrible sound of the underextrusion, but only when I print with a layer of 1.5mm. A layer of 1mm works good and the phenomen does not appear.

I have the latest Cura and Firmware running and tried different sorts of filament, but no difference. Any suggestions?

Those layer thicknesses are huge - underextrusion would be expected. Do you actually mean 0.1mm and 0.15mm?

How about the other settings such as speed and temperatures?

Also, what do you mean by horrible sound? A skip back is a pretty soft *tock* sound, nothing very violent about it so I'm wondering if there's something else going on.

Ok, I print normally with 210° PLA and 50mm/S. I mean this sound when the gear is skipping back.

An attempt earlier this day works...until 2 hours, then the failure comes again.

Now, he works fine too. But I think this could be not for a long time, its a 8h print. It´s a mess. I´ve put the little screw with gear on it a little bit backwards, maybe that was the failure.
