step motors - question

SparkSpark Posts: 49Member
I have bought a couple step motors with a longer pole coming out of them. So I can upgrade to a duel drive extruder, however, they won't run on my A1. The motors are fine, they work ( checked on a diff printer).  The A1 gives a tiny jerk if you hold the motor and then nothing...  doesn't move at all. Am I missing something? 

Here is one of the ones I bought: https://www.amazon.com/gp/product/B0787BQ4WH/ref=ppx_yo_dt_b_asin_title_o02_s00?ie=UTF8&psc=1

    The pinout on stepper motors is not standardised. You can identify the motor winding coils using a multimeter on continuity mode. Compare it against a stock motor and then switch the connector pins accordingly. If nothing turns, you need to swap two wires between the coils. If the motor goes backwards then just reverse the current in one of the coils, swap the wires on one coil.
