NEMA motors should all have the same wiring, it’s part of the standard in the nema specs, might be off on voltage, which would make sense. Check the specs on your motor and pull out a volt meter and check/adjust its voltage to match the new motor’s needs.
This is, of course assuming the physical connections are all dandy. (It’s possible something came loose in the conversion?)

Just to give more details, NEMA 17s can have 4, 5 or 6 wires. 4 wire versions are bipolar while the 5 and 6 wire versions are unipolar. While it would be nice if NEMA 17s were all the same, they aren’t. The standards apply to dimensions but not electrical specifications. Windings will change from manufacturer to manufacturer but are ultimately limited by its size. Because of this, all NEMA 17s will be capped in torque to a degree. Increase the case size with a NEMA 23 and you get more space for more windings, and so forth.

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)

Ok, so wire count is the same. I guess the remaining problem is current limit then?

probably, unless you’ve managed to get a bad connection or something- just something to look at when you’re opening it up to get to the pot. try and see if you can check the voltage specs on the new part, compare it to where its at. It’ll save you a lot of grief if you know where it should be before hunting around for it.

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