Replace Stepper Driver?

I am new so please tell me if i am in the wrong place.

My Extruder motor jiggles small frantic movements back and forth without filament inserted. (which is impossible to insert)

After some research i think i need to exchange the Stepper Driver for the filament stepper motor.

But where do i get the same original part? and how do i mount it?.

(just before the problem occurred i had soldered the heated bed because of a loose connection i think i did everything right)

I have a Prusa Mk3 I3

BIG thanks in advance! 🙂

RE: Replace Stepper Driver?

hi Jacobsen,

it could be as simple as your extruder motor plug not fully inserted, or one of the wires loose or broken. 
turn the power off for the printer
try disconnecting the extruder motor cable from the einsy, make sure that all of the wires are fully inserted in the plug, then reconnect it

then power up the printer and tryloading your filament again 

I try to make safe suggestions,You should understand the context and ensure you are happy that they are safe before attempting to apply my suggestions, what you do, is YOUR responsibility. Location Halifax UK

I thought you where wrong, the motor was moving back and forth in very small movements and it would probably only move one direction if what you sad was right. So i opened up to the board and ...... you where totally RIGHT!!!!! the cable was loose ... very happy and ashamed at the same time 🙂

Thank you soo much!  joantabb
