  1. Already tried that with some new stepper drivers
  2. This does the same, so this is strange.
Today the test went a bit better, but the extruder motor isn't that strong enough seems to be. When it's starting a new print, and it went a bit cold, before it would have a clog. When i try pushing it trough before the print. Try it again, print starts up, but then suddenly in the middle of the print it starts ticking again.. So how come????? I was making progress, and now it's in the middle of a print :x
What is temperature reading when it's ticking?
Tried printing a shot glass. Went allright in the beginning, but then half of the print it started ticking..

Here is an album with the images, as you see in the middle and at the top:

Is the cooling fan working when printing?

Please rotate the screw clockwise on extruder motor driver, the voltage between screw and GND should be up to 1V.

Already tried it, the ticking goes faster and slower. But still doesn't load the filament properly.. Maybe the system isn't compatible with 3MM ?

Oh, jesus, I ignored this point! I am so sorry.
Yes, if you want to print with 3mm filament, you need to change the extruder.
You can try 1.75mm filament.
Sorry for wasting your so much time.
