I made a lot of modifications to my controller circuit board. I reduced the foot print and also added in a disable/enable line for the stepper drivers to save energy when its idle.

With that, I included 2 new commands into the controller software, disable steppers, and enable steppers, updated code is uploaded.

Below is a modified screen shot of the board. I just took a screen shot and filled in the areas with paint to make sure everything made sense before I milled it.
