Great job with that Tree! 400 bucks was a bargain. How much have you put INTO it? I have a 330 Journeyman that still has the original control. It would be great to have things like rigid tapping. I don't think my machine has much memory, either, and it doesn't have the capability to drip-feed. A setup like yours would be nice to have, but I don't know that I could handle such an undertaking.
So, did you ever run the original control? The picture in another of your threads made it look like it hadn't been used all that much. Keep us posted as you make more progress on it.
