Feeder motor clicking and not feeding
Im having issue with the feeder motor not feeding so i removed the filament and opened the other gear but it is still clicking when no force is on it. Am i missing something?
RE: Feeder motor clicking and not feeding
Turn off the power, does the gear rotate manually?
It's in an awkward place and will take a bit of effort but you should be able to turn it with your fingers.
Cheerio,

Yes it dose without any resistance.

Look at the back of the motor, you will see the other end of the drive shaft. It is probably too uniform to see this easily so mark the shaft on one side so you can see it turn - now turn the gear again, does the shaft rotate?
Apply power as in your video, does the shaft rotate now?
Cheerio,

No it is also jittring like the video below: 20210317_122704[1]

And it turns just fine with power of (the outside too).

that can happen when one of the motor windings goes open circuit
I would check that the motor connector is firmly seated in the socket on the Rambo. and that all four crimp connectors are firmly seated in the connector shroud.
if this doesn't work test the motor wiring
there are
Green and Black, Red and Blue,
there should be continuity between Green and Black, and Red and Blue, but not between red and black etc
this link shows the basic connections

If the wiring is faulty there will probably be a break in the area where the motor wires are attached to the back of the extruder cable strain relief bar, behind the extruder assembly (where the cables become flexible) you could replace a faulty wire using heat shrink tubing and soldered joints. if required.

This is almost certain to be a wiring problem.
As @joantabb says, the most likely is a poor connection to the board. Pull and replug the connection.
If this doesn't fix it then, if you have a meter, check continuity as she suggests.
After that, if your printer is still in warranty log in to your Prusa shop account, go to support and raise a chat (bottom right in most browsers) and show them what you have shown us.
If the warranty has expired there is a good chance that mending or bridging the cable will work but if you're really unlucky the break will be internal and the motor must be replaced.
Cheerio,

Thanks for all the help, it was the blue wire that broke in the corner next too the nozzle cooling fan. Just patched it so no need for a warranty claim 😀
