Hi, after re-assembling my prusa I've got a problem - x,y,z axis work great, but extruder motor never responds. I try to extrude with "pronterface" and "repetier-host" with normal temp (180c). Prusa dont show any errors, but motor not moving.
I have tried to connect extruder motor to x axis port - its working!
I assumed that extruder0 port broke by short-circuiting. I have tried to change e0 pins in pins.h to e1 port.
#define E0_STEP_PIN 26
#define E0_DIR_PIN 28
#define E0_ENABLE_PIN 24
to
#define E0_STEP_PIN 36
#define E0_DIR_PIN 34
#define E0_ENABLE_PIN 30
But it is also not yield any results. A very small probability that broke immediately 2 ports.
What else can block extruder in software except minimal extrusion temperature?
what are the ways of diagnosing this problem?
