Howto reconfigure driver for extruder motor

My extruder went total dead after 4 years of service. After troubeshooting I defined that the motor driver on board is bad. So I need to use my left over free motor drive.
How can I make my Prusa use this free motor drive instead of my default one, once I move connector and motor chip.
Like you can see in attached file I want to move from red arrow location to black arrow location.

I figured it out eventually.
Found my motherboard type in Configuration.h (33)
Then in pins.h I located the pins def for my motherboard.
So I just exchanged the pin numbers for extruder 1 and 2 there


#define E0_STEP_PIN 36
#define E0_DIR_PIN 34
#define E0_ENABLE_PIN 30

#define E1_STEP_PIN 26
#define E1_DIR_PIN 28
#define E1_ENABLE_PIN 24

Didn't work at first
But then I got aware, moving my motorchip and connector , I missed out on also moving the 3 jumpers that is located under the motor chip
All this done I realized I could instead just have defined Extruder 2 in Repetier and used that ... not messing with the pins.h , recompile/reload.

See if I can run another 4 years without board failures he he

Or just swap the step sticks...

I don't understand step sticks. Can you clarify.

What you call motor driver is also known as a step stick. You can move them to other locations, or replace them if they fail.

Ok, thanks for explaining. Well my conclusion is that my step stick and motor is ok. I just moved the step stick to the free location on RAMPS board. So problem was that old location on RAMPS board is failing. Seems like that free location is pre programmed for second extruder .... at least in Repetier.

Ah, so maybe a trace is blown, or a solder joint has gone bad?

Yes. At the moment I won't bother to take it apart and investigate. Just happy I have it working on the free location.
