I have a stepper controller, what I guess is sometimes called a stepper controller. It has four pins that go to the stepper motor, and two that go to the DC power. The stepper motor has four leads colored blue, green, red, and black. Looking at the online documents, I see nothing that identifies which color goes to which pin on the controller. Any ideas?
The 4 wires connect to each end of two sets of windings (A+, A-, B+, B-)

It looks like there is usually a driver wired between the controller and the motor.

You might also be able to 'trick' the controller to go slower by telling the controller that the microsteps are bigger (if the driver provides 128 microsteps and the controller is set for 32, the motor will turn at 1/4 of the configured speed).
The controller tells the motor which direction and how fast to move.
The driver sends signals to the coils to make it move as commanded.
Very helpful, but the controller documents do not identify which pairs are match up to the motor leads.
Deleteyou wire the controller to the driver, and the driver to the motor. The driver will have the A+ A- etc. connections for the motor, and the connections for controller. You need all 3. Motor. Driver. Controller. There are integrated options, but that doesn't appear to be what you have.

That's just an example - not sure which driver makes sense
