External config

Hi
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.

If you have the new Cohesion3D LaserBoard there are no changes needed to the config. Here is a guide for connecting external drivers to the LaserBoard.

Once this is done your motors will be able to move with the Move Menu in LightBurn, but you may need to alter the Max Speed and Acceleration values located in the config on the SD Card. You will also need to set the proper current for your motor and the Microsteps which is done with the DIP Switches on the external stepper driver.
