I am upgrading my cnc controller and drivers and I am seeking advice.

My current setup has:
- C10 bob
- OMS mh110 drivers
- Linux software

I am switching to:
- DM556D drivers
- UCCNC software

The configurations I am deciding between are:
- AXBB-E
- C76 bob w/ 300-eth
- UB-1 bob w/ 300-eth

Any feedback/advice would be greatly appreciated.

Adrian
