I've just acquired a Tree Journeyman 310 Mill with a Dyanapath Delta 20 Controller. When I start it up I get the usual E-Stop error which I can clear. That is followed by instructions to "Reference the axes." I have been using the following procedure without success.
1) "Mode"
2) "0" (for Jog)
3) "R" (for reference)
4) "Enter" (with or without this key, no action)
5) "Start"

I get no response following these steps, which I got from a previous post. The boards inside the controller show all of the proper settings. The power is good and correct. When I loosen the cables at the servos I get limited and eratic movement. The connections are all tight and clean.

Any ideas? I'm awaiting the factory's manual arrival in the mail, but I'm not pinning all my hopes on that.
