    Love the Trolley jack Big "D" precision engineering at it's best. . .

    Regards Servos then good choice but the EdingCnc software I think is shit I just can't get on with it.! . . . Also which board is it because last time I looked the fastest board they had was only 125Khz which will be restrictive to RPM with servos with high count encoders.?

    IE: Presuming 3:1 gear ratio with standard 2500ppr quadrature encoders so 4x 2500 = 125000/(10,000x3)=4.16 rev/sec x 60=250Rpm you'll get from Servos before frequency runs out.!
    To get full 3000rpm which most servos run at you'll need 1.5Mhz frequency with 2500ppr encoders.!! . . . . .Unless you use electronic gearing but then you lose resolution so it's a trade off.!
