I didn't actually write any code, there was a library that I downloaded, and example code I inserted, called stepper test or something, it came with the library.
You still need to post it so we can see it if we are to make sense of your problem. (Don't bother with the GRBL code - it is too complex 
)
Try this Simple Stepper Code - it should work fine with a TB6600
