1. Tormach 440 doesn't have a Break Out Board. It uses the Leadshine MX3660, which is kind of an "all in one" solution which incorporates BOB and stepper drivers into one package. It is a new product, and as the OP will tell you, really doesn't seem ready for prime time. Tormach has already switched out the first generation models on the machines they sold when they found they are ALL defective.
2. This is on the Tormach forum, and is a Tormach 440, which is only offered with "PathPilot", an adaption of LinuxCNC.
Back OT: this actually could be a problem where an axis is driven past the limit switch position, and so won't move. Is one of the axis all the way to one extent?
You can physically move the axis back. Take the cover off the coupling between the stepper motor and the lead screw, and (with the machine powered off) turn the lead screw by hand. It might turn easier if you use a section of rubber or leather belt, but you should be able back it off the end. Then once it is in the middle, power the machine on and move the axis using the keyboard. Then reference the axis. If it gets stuck again, then maybe the limit switch is bad.
If that isn't the issue, with the machine powered up, and e-stop disengaged, what is the status of the red and green LED by each stepper motor cable connection?
