[HELP] Extruder Stepper doesn't work!!!!

[riko.roma]

Hi Guys,

I tryed many many firmware for my prusa i3x, but the Extruder Stepper doesn't work.

I used the fw I3_Pro_x firmware ( http://www.geeetech.com/forum/viewtopic ... 10&t=17046 ) and other many fw but null.

I tried to change the cable, the A4988 driver, but doesn't work.

I tested the stepper and work very well if I plug the extruder cable into the X or Y from the motherboard, using the LCD I can see that working.
Please see my video.

Please help me.

Thanks.
Riko

Hello you need to heat up your hotend, the extruder will not move until the temperature reaches 170 degrees~~
