So anyway, after unboxing when trying to home everything the "Y" axis would not go up. In fact it would only go down. I did enough diagnosis to suspect that it wasn't the RAMBO board, but didn't want to muck around too much. Support initially responded suggesting it might be an end stop issue and wanted to setup a phone appt. This got me to trace the end stop wires from the RAMBO board all the way around and sure enough, that was it.
Damage from where UPS either dropped or slammed it against something:
The Orion otherwise was packaged quite well, but I guess there's no protecting against UPS. Possible recommendations though are to use metal screws instead of nylon/plastic and don't route any wiring between the PSU and the MDF directly.
Support was very helpful through this and they did say they were already working on a new packaging system that might avoid this.
