Nothing Extruding! Please Help!

I built the  i3 MK3S kit, and the calibration weant smoothly with no errors, but once it gets to the meandering test extrusion, nothing extrudes. The feed gears move, the hot end is hot, but the filament is not even melted when I unload it. However, I can see small ridges where the feed groove gripped it.

Some pictures might help us help you. Also check to make sure the extruder gears are aligned and the set screws are tight.

More info please what fillament, what temperature, did you get hotend factory assembled - it could be a temperature issue- try manually increase the temperature , did you cut the  fillament tip correctly?

What happens when you load the fillament? Does it come out of nozzle?

I solved this one on my own - apparently I needed to use more force when feeding the filament for it to reach the hot end.

Now I'm dealing with crash issues just trying to print Benchy.

The crash issue can be related to bearings or belt tension at the X  or Y accellaration moment.

@booszhius

Did you lubricate the bearings?

if not, it might be time to do some maintenance...
