Both the Axbb-e and the UC300 are identical regards the motion controller side so the UC300 offers nothing extra other than more ports (I/O)
The only real difference between the 2 is the secondary analog output and the way you install a 5th/6th axis. And of course the 300 needs bob's or equivelent.

1. Some servo's use 2 analog inputs for hybrid speed/torque mode. If required, use uc300.

2. Some have problems adding a 5th/6th axis to the Isolated outputs on bbe. Opto's seem to be non high speed (basically for switching). If you need to use a high khz kernel for pulses then use the non-isolated outs on port3 with a high speed bob (ucsb type + IDC26 cable).

Other than that the controller is exactly the same.

Haven't fired up my 300 yet, but the unit looks like a 'proper job'. Big step up from my £5 thing
