Testing stepper motor fails

I am upgrading to SLB and want to test all the wiring/connections prior to swapping out the controllers.
On a test bed everything is working as it should, except the motors.
I only have one spare stepper motor and I am connecting it to each port individually.
I get no response from XYYZ.
They do not lock when I activate the board and I can feel no “activity” when I hold the motor.
The A axis works using the same motor.
I am connected via the green phoenix connectors and the wires are colour connected all the way to the motor.
I have 4 green lights on the SLB board.
Any suggestions on what may be happening, or in this case not, would be appreciated. Thanks.

@nifty I guess that I’ll ask the first questions.
Are you using gSender to connect? If so, what version?
Are you connecting using grblHal as you should be?

Thanks for replying.

I am running windows 11 - GSender ver 1.5.6 and grblHAL.

In GSender I can simulate movement but the motor is not turning. No resistance so they are not powered up. I have soft, hard stops and homing turned off. I have 4 green LEDs lit up in the B column, beside the connectors.

One of the issues I have is I cannot find any information on the pin out for the steppers so besides the colour photo I have no way of knowing which are the A+ A- B+ B- pins. With 24 possibilities it is a bit hit and miss guessing, unless I am on the wrong track with my understanding.

Follow up:

Watching a Jesse Sparks video I noticed he had wired his SLB differently to the manual so I matched his wiring, reset the board and the stepper motor is now working.

Now to get the rail leds working correctly!
