Hello everyone,
I am 3D printer Prusa I3 pro B owner. I had some issues with extruder. Simply it doesn’t move. I did some test.

This is the list what I had done so far:

• Reapload firmware by using Arduino 1.01 and the newest one Arduino 1.8.1

I had taken firmware from this post

viewtopic.php?f=20&t=17046- from here I had downloaded firmware for my prusa i3 gt 2560. It was uploaded correctly.

No results.

• I already had done some simple diagnosis:

1. Just swamp an extruder cable to another slot ( Y axis). It worked. Extruder move with no problem.
2. Next I swamp stepper driver from extruder slot to X axis slot. It worked. It hasn’t have any problem. Also I had checked all possible issues with this stepper driver A 4988
viewtopic.php?f=19&t=17097 . I hadn’t find any problem with this part. Conclusion it is fine.
3. I swap stepper driver from X axis to extruder slot . It didin’t work

I had checked post how I can deactivate E0 (default slot) and activate E1 (changing pins numer in pins.h file). I couldn’t find link dirtect to this post now. This approach do not fix my problem.

I had tried almost everything. I feel soo confused now. In near future I have to print my parts for very important project, but I can’t.
I am affraid that steeper slot could be broken or cable slot for Extruder

Any help will be highly appreciated.

I am almost certain you have the same problem I did - the extruder won't work below some high temperature - I think it's 160. It'll claim to work, but nope... It sits there doing nothing.

Warm it up, see where it gets you.

Hey,try what AbeFM said first,and then refer to this post:

Hi guys,
I had changed my broken E0 slot and now its work fine, but now I had some some issue with clogging hot end (brass).
So I decided to buy new hot end (hardened steel).
What do you think about that ?
It worth to use hardened steel hot end instead of brass hot end ?

Have a nice day

I'm no expert-.-but I don't think the to material matters that much. Make sure it's clean though.

Totally agree with you...
