Extruder will not step, SD card will not print

have checked wiring continuity OK. Replaced the driver /swapped driver with one I know to be good with no luck. suspect a firmware issue but can't see anything out of place. All the other drives XYZ are homing fine 


  • That is no server question!

    Assuming you use repetier-firmware send
    M302 S1
    to allow cold extrusion with extruder. Otherwise it will only move when being hot.

    sd card requires vfat formatted card or it will not be detected. Must also be mounter (done automatically at startup). Check in console if mounting works or not. Then test what
    returns. Should show files on sd card.
