calibrate the steps of the x and y axis

How can I calibrate the steps of the x and y axis.. unfortunately I can't find anything in the documentation

@axiom Assuming you have pulleys directly attached to the motors then start with the number of steps for one revolution of the motor. For "normal" 1.8 degree motors that'll be 200 full steps (360 degrees in circle divided by 1.8 degree step), for 0.9 degree motors it's 400 full steps. Next take the belt pitch (usually 2mm) and multiply this by the number of teeth on the pulley (e.g 20 teeth) which will give you the distance travelled in one revolution (e.g 40mm). Divide the number of full steps per revolution by the distance in mm travelled per revolution (e.g. 200/40) which gives you the number of full steps per mm (e.g. 5). Multiply this by the micro stepping you plan to use (usually 16x). So 80 (micro) steps per mm using the example motor, belt pitch and pulley size given.

xy_steps_per_mm = (motor_steps_per_rev ∗ driver_microstep) / (belt_pitch ∗ pulley_number_of_teeth)

@axiom the Motors section of the config tool at https://configtool.reprapfirmware.org/Motors wil calculate the steps/mm for you if you supply the parameters:
