I have same issue. Stepper motor and wiring are good but on M5-M8 extruder not working. Any one have some solutions ?

Have you done your configuration checks? Looking at klippy log, it looks like your extruder is not hot enough. As a safety feature Klipper won't allow the extruder to work below a certain temp. You can check to see that the motor is working by verifying your stepper motors. Use STEPPER_BUZZ command. For extruder it will be (STEPPER=extruder). Make sure there is no filament loaded before doing so. Otherwise bring up your heater to extruder temps and then try extruding some material.

@Seriy2103 When setting up Klipper. This step is important, as it allows you to safely verify everything is working without damaging your printer and/or its components.

I did everything as described in the guide, nothing helped. Most likely, something is wrong with the pins step_pin, dir_pin and enable_pin. Everything else works correctly.
