I have been looking at the AXBB-E controller with closed-loop servos. Obviously, in hindsight this is the right gear for the job but it is my fault for not putting enough research into this. I just have to make the most of the situation and get it sorted as best I can.

Do you need to use more than 4 axis?.
I know of another guy who has the AXBB-E. It is a good unit however.....
If you want to use a 5th or 6th axis you need another breakout board to go into channel 3's non isolated IDC port.
The optocouplers on the isolated channel 2 outputs aren't fast enough for pulsing by the looks of it.
He got a UCSB board for chnl 3 and all is well.
Other than that they're decent units.


I had the 'kit' type electronics on my mill and almost the whole lot has been replaced due to lack of performance.
Went with the UC300eth, UCBB, and was going to switch to closed loop gear later on.
Closed loop is a little misleading though so I'm hoping to eventually change to Lichuan servo's instead.
