    Re: I NeeD HeLp PLease AM882 a good choise

    I will answer some of it to get you going. First the power supply looks ok from the picture but the output cable (66V) cable would need to be a bit bigger than it looks on the picture at least to...

    Re: I NeeD HeLp PLease AM882 a good choise

    Great good to see you took Jons good advise. Those motors while still a little higher than some motors of same power are still have low enough impedance not to be restrictive.

    Re: I NeeD HeLp PLease AM882 a good choise

    The inductance is marginally worse than the CNC4YOU (and Zapp) motors, but you're unlikely to notice much difference assuming they do actually meet the specifications. I measured the inductance of...

    Re: I NeeD HeLp PLease AM882 a good choise

    I've had several sets of TBI linear rails now and they have been fine and while not quite smooth has Hi-win they are still more than good enough and lot cheaper. I've been using SBC Linear rails...

    Re: I NeeD HeLp PLease AM882 a good choise

    Then you're basically stuck if you want them for a reasonable price. Will CNC4YOU not ship to your country? If not, then you need to find 3Nm (425oz-in) motors with 3.2mH phase inductance. They...

    Re: I NeeD HeLp PLease AM882 a good choise

    Just because something that it better is available doesn't mean you need something better. The machine will run perfectly well with DQ860MA drivers.
    The cheapest AM882 drivers on aliexpress are...

    Re: I NeeD HeLp PLease AM882 a good choise

    Either is plenty stiff enough. Sometimes people go for the 20mm rails just to make it easier to to make the parts they mount to with minimal machining. You need to draw it and work out which is best...
