I confirmed that the sample code works. However, the micro step does not work well. The step width is the same even if I change the settings. Is there a special setup procedure?
@felmue ..Thanks for that a colleague sussed that out just before I read your reply but many thanks as you were dead right... as all up and running now. For anyone reading this reply the illumination of the centre main on/off button is LED #4 I didn't realize that the LED's are multi colour until I studied the circuit diagram/schematic ...cool !
