UM 2 Go clicking

[HugoG 0]

Hi,

 

I am new to Ultimaker printer, and I just got my hands on a lightly used Ultimaker 2 Go, which doesn't have any problems so far except one:

When I try to feed it filament, it all goes fine until the step where it should slowly push filament through the nozzle until it comes out. When it comes to that step, the extruder stepper starts moving the filament forward for 0.5mm and clicks back 0.5mm. I've tried to readjust the feeder tension making it tighter and loosening it, but both don't do anything, except making the clicking slightly louder/quieter.

I hope one of you what's going on and what I could do to fix it.

 

Have a great day,

I have sometimes the same problem, but immediately after putting the filament into the feeder. So my issue is that the feeder is maybe dirty and cannot grab and transport the filament forward into the Bowden tube.

 

Your issue is nearly the same, the click sound comes from the feeder, trying to transport the filament forward but it cannot and the filament pushes back a little bit. You will also see that the filament is grinded when you unload it. 

 

But you say, it will be forwarded through the Bowden tube to the nozzle. So then check if your Bowden tube is correctly mounted in the print head and check if your PTFE couple (the white thing with he spring) is deformed or looking bad. Maybe the filament pushes against this part and cannot be transported fully to the nozzle.

Thank you very much for the response! I opened the PTFE tube on the side of the extruder and put it back in, and now it prints perfectly! I think it was pushing to the coupler indeed.

Great! ?

Happy printing....
