That said I can't for the life of me get it to work lol. I am using Saintsmart uno and 1602 lcd six button shield and a tb6560 driver. I can load the sketch no worries but I dont seem to be able to get the driver part working. I have the liming sketch up and running ok. My question is I can't seem to find a wiring diagram .Is there one posted?
John, first of all, I have never used the Sainsmart but a few people have used it with this sketch. I think that you may need to modify the LCD library in the keyboard sensing code and its been documented bys others in my other thread linked to in the first post. However by the sounds of it you have got this part working. If the displays and menus work, it will be fine!
So its always best to start with basics in the Arduino core library before you use a complex program. Maybe this one. https://www.arduino.cc/en/Reference/Stepper
So once you know you have a working stepper driver, install my sketch and configure the settings including the step and direction pins in the setup menu. If you have not done that, it probably is the reason why nothing moves.
There is not much to the wiring. step+ and dir+ go to the relevant digital pins and step- and dir- go to the Arduino ground. Attach the high voltage for the stepper to your controllers stepper power terminals. I'm not sure of the TB6660
but in some cases you need active low wiring so check your documentation. I've never had to do that with the Arduino though.
