Ultimaker S3 loading procedure not working right

Recommended Posts

Posted (edited) · Ultimaker S3 loading procedure not working right

So I follow the instructions for loading a new filament. I place the place, manually insert the filament in to the feeder. Sometimes I have to release the lock to manually feed it up, but other times it grabs and advances the filament on its own.


The issue I'm having is that it will say it is loading the new material into the print core, there is a waiting period here, I'm assuming to heat up the core. Then it makes that whining noise it makes when it advances the filament up the tube. It will then say to confirm when new material extrudes. Its at this point that I get an issue. It slowly spits out a random length of material, sometimes long, most of the time just a few mms, but it always stops at some point before I press the confirm button. Then it times out and goes back to the back corner of the machine.


It seems to print fine, but i always have a bit of the old filament that has to be worked out in the beginning of the print. Seems to happen regardless if i use ultimaker or 3rd party brand filament.


What am I missing here?

Hi Jordan, 


You are not mising anything. looks to me that thenozzle is not purge long enought. One thing you can do is once the printer has loaded the filament, unlock the lever on the feeder and manually push the filament and once you see the material coming throu the nozzle lock the lever and then let the printer purge the nozzle. You should get a string long enought that the new filament has completly purge the old one.

      Through this post I would like to further explain what we are doing, and what you could be doing. 
      Our efforts consist of 2 layers. First; connect medical institutions and hospitals to (local) 3D Printing hubs to help them print parts of which a 3D model already exists. And second, contribute to design the necessary part and then have it printed via a (local) 3D printing hub. Experts are available from within Ultimaker and from within our network of 3D printing experts.
