    I “dropped” this motor in as a replacement for my Ender 3 V2 extruder motor. The spare cable was useful to allow me to swap the wiring slightly, as the Ender and LDO configuration is slightly different, took about 1 minute of trial and error to get the motor spinning smoothly in the correct directly. Now it’s working PERFECTLY. The old motor ran at about 60-80C, this one runs cold – didn’t change the Vref at all. And most importantly, no more skipped extrusion steps.
