Stepper Stops Extruding (Video)

Hey all,

Having an issue with my extruder stepper. It works for a while, then just starts clicking, please see the video.

Its not clogged. Once the stepper stops turning, if I take the bowden tube out of the hot end, it still does the same thing.

Turn the printer off and back on after 20 mins. heat up the hot end with the bowden tube still out and it works. Very confused as to what this could be.

I've got a Ramps 1.6 board, with my steppers all set to about .55v

I've got some things I urgently want to print to finish some projects, so any help would be great!!!

Thanks guys

Do you have a spare stepper driver? I would replace the E-stepper driver first.

Good idea! I think I have a few floating around. I'll try it tonight

Ill let you know

Now the Y stepper is not working HAHA

My god! its always something

Ok Y stepper was a wire that had come out of the crimp, fixed that, all working.

Changed the E stepper driver to another, but I'm still having the extrude issue. It prints perfect, nice first layer ect. but about 10% though the stepper just starts ticking (as per the video)
