    Finally got around to putting some test electronics together, just need to connect the motor and flash grbl onto the arduino. Would be awesome if someone could take a look at my wiring befor I do anything too stupid. I'm a bit unsure about the earth at the moment. The negative enable, step, and pulse are all connected together and the ground pin on the arduino. And mains earth isn't connected to anything at the moment.
    Once I have one tested and working, will test all three together.
