3D printer problem

#1

I just finished working on the 3D printer and start testing it …

Every thing is fine except the extruder’s stepper motor , it don’t spin , I debug the problem as following :

  • Extruder’s Stepper motor works fine , / test with x-cor port ,

  • Motor driver board works fine / switched the driver boards with x-cor , x-cor stepper worke fine after switching

  • Conclusion most probably the problem is in the RAMPS 1.4 shield ,

Please if any body can help to solve this problem …

thanks

Could you post some pictures of your setup maybe?

Thanks I figure out a solution , I changed the extruder (Stepper Motor Cable , Driver Chip , Jumpers ) to E1 and did minor modification on the firmware as following :
file : pins.h from line 339 :

 /*  old : 

#define E0_STEP_PIN        26 
#define E0_DIR_PIN         28
#define E0_ENABLE_PIN      24
#define E1_STEP_PIN        36
#define E1_DIR_PIN         34
#define E1_ENABLE_PIN      30
*/
// New 
#define E1_STEP_PIN        26 
#define E1_DIR_PIN         28
#define E1_ENABLE_PIN      24
#define E0_STEP_PIN        36
#define E0_DIR_PIN         34
#define E0_ENABLE_PIN      30
//

It works great now :slight_smile:
