I've got all three motors wired and checked out now. EMC2 is happily driving them through the Gecko G540 on my bench top. All the currents and temperatures look normal for motors running with no load.
Now to start assembling the microCarve A4 itself. Hurray!
My promised pics got delayed by my daughter borrowing my camera. I've got it back now. The battery is dead, of course. It's on the charger.
I'll be getting some pics up later.
For now, more building, less posting.
