Filament not coming true

Yesterday my Vertex was completed. After a couple of succesful prints I wanted to start a nother one this morning. After a half hour I checked on the print and the filament was stuck.

After some testing I found out that the filament has no grip on the extruder stepengine. Is there any way to crank up the stress on the spring so that it has more grip? Are there other options to resolve this issue?

Grtzzz… Fr33z

I am also a Vertex starter… so not an experienced user. The strength of my extruder spring is so high that I hardly can open it to load the filament. You didn’t change filament after the first succesfull prints?

Yes I agree with SlowFoot weak springs would be the first…

Most likely you overtightened the lower m3 bolt that also functions as the release lever’s pivot point. If that’s not the issue, probable cause Nr° 1 is a clogged nozzle
I had it a few times that when I started a new print the feeder stepper starts tapping as it couldn’t push the filament further in the bowden tube.
Most likely this is due to a clogged nozzle. BUT in my experience I could get it open by “Helping” the feeder by pushing the filament in with a little force.

What I would do:
If that works and U get material to extrude (nozzle not clogged) but it stops when you’re not helping it in any-more by hand, remove the filament spool and look from the side into the extruder feeder. check if your filament is actually inside the groove of the pulley, if that’s the case remove the PTFE tube on top of the feeder (push some filament into the feeder while doing that) so now U can pull the filament trough from the top. Put your hand inside the printer and feel on the back of the stepper engine if the engine axle moves while pulling some filament trough. If it doesn’t rotate you’re pulley came loose and You’re going to need to remove the complete feeder system and reseat the pulley correctly.

If that’s all good, get your calliper and measure the filament you loaded… I assume its no good in that case…

Found the f*****… The m3 screw was loos… So the polly of the extruder wasn’t turning around…

Thx for the fast reply’s

Great to hear you found the issue!
