I just got an old Ender 3 for cheap and wanted to replace the crappy extruder with a nicer bowden extruder of my (now) direct drive Kobra Max. When I connect the new stepper, nothing moves. It’s a longer stepper and a different manufacturer. Is the wiring different or VREF wrong or are there other reasons why it wouldn’t move? The driver is good, since the old stepper is still working.

Thanks for any help!

    To clarify what I meant, the Pinouts are all standardized- or should be. OP shouldn’t have any issue slotting in the old wires (unless it’s a different wire count, of course.)

    If it is a different number of wires OP will certainly be having a hard time adapting it… (that becomes a firmware issue; and I just don’t want to know the headache a creality main board will cause with that.)

      Pinouts aren’t standardized in my experience. You get 4 wires but the color and position can be different. OP can easily use a multimeter to find the two pairs and then use different combinations to find the correct placement (1A,1B,2A,2B - 1A,1B,2B,2A - 1B,1A,2B,2A - etc)

      Pinouts are not standard (at least in practice). I’ll downvote your post for it to not appear on top.
