Reconfigure Stepper Driver Signal Pins

If the wiring is physically correct but the motor remains unresponsive, the firmware pin mapping may be mismatched with the physical driver connection. Cross-reference your board's schematic with the printer.cfg file to ensure step_pin, dir_pin, and enable_pin are assigned to the correct physical GPIOs on the RP2040.

Tools needed: Board schematic/pinout diagram, Klipper configuration file.

Verification: Perform a 'STEPPER_BUZZ' test in Klipper to confirm that the signal is reaching the driver and resulting in motor movement.
