Some drivers require a couple of microseconds after the direction pin is set before you start the step pulse. The original plan was to [use the RMT feature](http://www.buildlog.net/blog/?s=rmt), but that has issues when trying to use it in an Interrupt. **This is typically a option in Grbl that is not used.** -2. **Limit Switch debouncing** is not supported yet. It does not seem to be a problem on my test rigs. The dev board uses R/C filters on all inputs. -3. **Step Pulse Invert:** This has not been fully tested.

I suggest starting with that if For basic instructions on using Grbl use the [gnea/grbl wiki](https://github.com/gnea/grbl/wiki). That is the Arduino version of Grbl, so keep that in mind regarding hardware setup.
