@ava Hi ava. Glad to know you. Have you tried to test the extruder manually? 

1. Set Preheat PLA. wait for the nozzle temp to 200℃.

2. Disable the stepper, then manually rotate the extruder, see if the filament comes out properly.
If yes, no problem with the mechanical structure of the extruder.

3. Set the Movement of the extruder on the display screen, see if it rotate/push the filament into the nozzle. If you can share a video of how it is going on here, that would be helpful.

@kevin

I have the same problem with my CR-X.

I pushed the fiament maualy, and it is comming uot of the nozle.

But I cant find in the menu how I can command the extruder to drive manualy.

@john I have no CR-X, not sure what is the display looks like. But usually, you can command the extruder move on the "Refuel" page if there is no extruder movement instruction on the "Move" page. 

Thanx for your reaction,

I tried the refuel option, and indeed there i kan feed.

If I feed there is an reaction in the axel of the feeder, bit it is not rotating.

Now im going to remove the feeder from the printer, and see if it is rotating without the feeder clamp.

@john It is not rotating? But it can feed? So what is condition if you feed the filament by setting display.

I now have only the feed engine, and as i feed by setting display, i feel the engine is rotating, but the axel is not rotating.

In my display there is a cross in disable motor, and I cant remove that cross.

Is there a possibillaty that this is the reason if no feeding.

@john I can not imagine that the motor is rotating and the axel is not rotating. How could you know the motor is rotating if the axel is not rotating.

You can push the fiament maually, but no filament comes out if you set feed in "Refuel" page , right? 

Please set 100mm feed in, the axel is still not rotating?

No the axel is still not rotating.

If I put my finger on the axel, then I can feel that inside the motor somthing happends (vibrations), but no rotating.

@john Switch the extruder cable with cable from Z-stepper, maybe cable is faulty.. If you can extrude by moving Z in menu, then the motor is ok..

I did switch with the Z-stepper, and it is rotating.

Back on the feeder it is just (feel it is magnetic movement), but not rotating.

That is for both the feeders, so I think its the software perhaps.

Can I start from scratsh, fabricmode??

@john So you mean extruder motor is ok?  Can also move the bed when extruding in menu? (with hotend temp. above 180 or something like that) 
Motor only vibrating sounds like missing connection.. Motor has 2 coils, but only 1 is powered now thus not rotating. 

Both my feeder motors are not rotating.

If I held my feeder motor on the axel, and feed then, than the motor turns very very very slowly.

By feeding 10mm, it turns les than 0.5 degrees.
