Stepper Motor Status LEDs

I have a stepper motor, its a few years old, with no markings. I assume it came from Aliexpress.

The motor looks just like this:

The controller looks like this:

I am using a ESP8266 to drive it.

Cabling I have:
#define IN1 14 //GPIO 14
#define IN2 12 //GPIO 12
#define IN3 13 //GPIO 13
#define IN4 15 //GPIO 15

I have tried lots of example code, and no matter what I do, I only get lights B and C flash.

THe motor is spinning ok (i assume, it looks ok anyway). But I assume I should have more lights? Is the lack of LEDs a issue?

Have you a GND connection to the ESP8266?

I wonder if the fact that the ESP8266 works at 3.3v is the cause - maybe that is marginally too low for some of the LEDs? Have you tried the driver with a 5v Arduino (Uno, Mega or nano) ?

If the motor is working properly I would not worry much about the lights.
