[SOLVED!] Extruder stopped during first print

Vertex 3D Printer Vertex - Issues while printing
1

Hi everyone,

i finally assembled the k8400, wooho!
Right after that i started the first print, the keychain vertex logo.

The first layer was absolutely perfect! Then i realised a clicking/ticking sound comming from the side of the printer.
After a few secounds i found out, that the extruder motor, has not enough toque/power? to move the filament forward.
You can see that the motor tries to rotate but cant? Click … click … click. I then tried to unleash a little of the pressure coming from the release lever but this didn’t seem to chance anything…

I can’t understand or solve this by logical thinking. Why did the extruder steper motor the first, lets say 10 minutes perfect and then stopped working?

Please people help me :frowning:

When this happens it’s most often because your nozzle is clogged. The extruder is trying to push the filament that can’t move forward.

Don’t extrude over 200° for PLA and 225° for ABS (stock values seems to be a bit too high).

Hi,

thank you for your answer. I used the standart temperature of, i guess it was 190°?
Also i was absolutely precise while building the nozzle. I had the exact value in lenght to +/-0.00mm.

Is it even possible that the nozzele clogs after just the first layer? I used brand new Velleman filament out of the sealed bag.

But indeed, now that you say it, i had the feeling that i heared a very silent crackle noise in the nozzle some time before it stopped working.
Will check that as soon as i come home. Any info where to find a “how to unclog a nozzle procedure”?

Best

SOLVED!

Hi everybody,

i solved it. The filament Pulley on the stepper had accidently ripped of some material from the filament wire. Due to the lost material on that particular spot of the filament wire, the pulley wasn’t able to push the filament further. And then decided to click click click ^^

I don’t know why this happend but here is the solution procedure:

  • unload the filament
  • cut the 70-80 cm of filament that was traveling the distance from extruder to the printhead, and trow it away
  • load the fresh, unused wire from the spool in the printer
  • Enjoy!!! :slight_smile:

To make sure, that you dont have a clogged nozzle, and to try my solving procedure:

  • heat the nozzel up
  • unload the filament
  • push a piece of filament trough the head, if it comes out you obviously haven’t a clogged nozzle (like me)

heres also a foto of the ripped of piece on the filament wire.

The extruder wheel is very powerful on the Vertex. It will flatten or even crush some filaments, particularly PLA mixes, such as Colorfabb’s brassfill or woodfill type filaments. You need to check with that type that you don’t inadvertently refeed in old filament.

It’s possible to shorten the Extruder spring by cutting of a coil or more if you want to print softer filaments but be carefull as if there is not enough pressure on harder materials the retracts will suffer first…
