    Nick from what I understand those controllers will not do slave axis as you require. Although you can connect the step output to two drives I would certainly NOT recommend it. You need a controller that will handle dual homing if you intend to use twin motors as it will then square the gantry every time you home the machine.

    the stall protect will tell if you if it's out of square
    This is not true. You could be out of square say about 5mm and the two motors would still run also stall detect as I understand it does not work below about 300rpm

    Oh I am busted....haha.
    The two am882 are here the other two am882h is on the way,I am waiting also for my toroid transformer to build the power supply.
    I can not decide about the bob and motion controller ,I need something to move four motors for now and one more for the A axis in the future.:-(

    What are you ruling out?
    Several BOBs are 5 axis?
    Are there motion controllers that are only 4? (Except the stand alone stuff you talked about above)

    I believe this is the only exception and I can tell that I am leaning towards the uc300 since the DDSCV can not support my four motors and a fifth for a 4th axis in the future,but about bob...I can't decide. :-/

    Any suggestions are welcome....

    I have no ideas for you.. I went with the 5$ bob.
    Beginning to question if that was a good plan !

    All the expensive ones seem good... But expensive ;)

    Cheap Bob's are like playing Russian roulette with a nearly full magazine.!! . . . . Long term they are not worth the hassle because at some point they will fail or cause issues along the way which will appear like coming from other areas of the machine. Before I started with CNC I had full head of hair and now I Dazzle planes on sunny day and I blame all on of cheap BOB's.!!!
