Did the filament get tangled on the spool stopping the filament for a short time?
Can you move the bed down about a 100 mm and center the print head in the middle then heat it up using the manual control?
Do all of the motors have a good connection?

I don’t know for sure since i was away when that happend, and when i got back i saw it missing a piece.
All the manual controlls seem to work fine. and motor connections? i think they are alright since i can move them manually.
About the slicing, i don’t see any parts missing when i look at the preview so don’t think thats it.
This is sometimes a sign that the small 23mm PTFE tube inside the nozzle is not up to spec (to long or to short) But I would first run some more test prints and see if this problem returns. If it does then it would be wise to open up the nozzle and check the PTFE tube.
After some more printing im not really happy with some of the prints.
Since this is pretty new to me i don’t know what to do to solve this.
What i noticed was that the filament stepper motor starts making strange noises when this happens.
It sounds like the filament gets pushed back between the stepper motor wheel and bearing.
I did manage to get better prints by losening the screw that holds the bearing leaver in place, but still from time to time it starts messing up the prints.
The image below shows what the result is when the stepper motor starts making some strange nois.
This is sometimes a sign that the small PTFE tube inside the nozzle is either to long or to short. I like you said this keeps on happening I should open up the nozzle and check inside. There should be no PLA residue between the PTFE tube and the brass nozzle. If there is residue that is a sign the tube was to short or the cut face was at an angle. If you see that the PTFE tube is a bit squished at the end it means that the ptfe tube was to long. Either can cause this problem.
Clean out the peek part as much as possible. Do not make a longer piece. Try to hit the 23mm mark and pay close attention to the cut face. Make sure it is as flat as possible and perpendicular to the tube. Use fin grit sandpaper if you must but be sure to clean the tube afterwards.
I have the same issue but i think i have found the reason for it.
It happens when the printer has worked for a while and hasen’t done any retractions.
But if you have 1 or 2 retractions per layer there is no problem.
So i’m slowly lowering my flowrate and it has helped alot,i’m currently at 85% with ABS
Alright that does sound like what happens when it goes wrong.
Since i’m pretty new with 3d printing, could you guide me to where i can change that setting?
I only have 15 hours of 3d Printing experience so i’m a total rookie too;)
I use the “manual controle” tab next to the slice tab. Click it and you will find
Feedrate,Flowrate and fan contoles
Yesterday i received a new PTFE tube and installed it. some prints are looking much better then before.
But the issue isn’t solved.
It still stops pushing out filament when a retraction happens.
You can clearly hear that the teeth on the wheel that pushes the filament is slipping/grinding over the filament.
When i’m printing solid objects without small details it works fine.
This item here is what goes wrong, when printing it needs allot of retractions for the teeth of the skull. perhaps anyone could try printing this and see if it causes problems? http://www.thingiverse.com/download:756305
Does anyone have some experience with this? and knows how to solve this?
