As I have a Arduino UNO and the GRBL CNC shield
In my simple thinking i changed the code as such.
#define DIR_EL 6 /PIN for Elevation Direction/
#define STEP_EL 3 /PIN for Elevation Steps/
#define EN 8 /PIN for Enable or Disable Stepper Motors/
#define DIR_AZ 5 /PIN for Azimuth Direction/
#define STEP_AZ 2 /PIN for Azimuth Steps/
But with no result. So did I mis something
