Introduction to the Corresponding Relationship between Arduno and Module IO Ports
The basic control pins of the stepper motor are required, and other pins are only used in engraving machines or 3D printers. We will not explain them in detail here, and the IO correspondence is shown in the figure above.
Arduno - Expansion Board
8- EN (stepper motor drive enable end, effective at low level)
7- Z. DIR (Z-axis direction control)
6- Y. DIR (Y-axis direction control)
5- X. DIR (direction control of the X-axis)
4- Z. STEP (Z-axis step control)
3- Y. STEP (Y-axis step control)
2- X. STEP (step control of X-axis)
The following is a simple stepper motor control program,
#Define EN 8//Step motor enable end, effective at low level
#Define X_ Dir 5//x-axis stepper motor direction control
#Define Y_ DIR 6//y-axis stepper motor direction control
#Define Z_ DIR 7//z-axis stepper motor direction control
#Define X_ STP 2//x-axis stepper control
#Define Y_ STP 3//y-axis step control
#Define Z_ STP 4//z-axis stepper control
Note:
Due to the different monitor and light effect, the actual color of the item might be slightly different from the color showed on the pictures. Thank you!
Please allow 1-2cm measuring deviation due to manual measurement.
