I have an external stepper drive to x axis, how config the file in sd for the enable and dir and pulse signals?
I must change the pin assignment or the board work in automatically?
I look in the config.txt and i found this
Stepper module pins ( ports, and pin numbers, appending “!” to the number will invert a pin )
alpha_step_pin 2.0 # Pin for alpha stepper step signal
alpha_dir_pin 0.5 # Pin for alpha stepper direction
alpha_en_pin 0.4 # Pin for alpha enable pin
alpha_current 0.4 # X stepper motor current
alpha_max_rate 24000.0 # mm/min
alpha_acceleration 2500 # mm/sec²
Thank you at all.
