    Just taken delivery of a chinese TB6560 based CNC stepper driver board.

    When I connect up my steppers, the sound from them is akin to water rushing through pipes (the same motors connected to another Allegro A3977 based driver board .... silent as can be)....so what's the noise all about - it makes me want to run to my missus & ask for some Daz.
    :lol: hahahaha!!! buzzin !!!


    iv got the 5 axis TB6560 china special...they have always sounded like that to me, i can only think the Allegro A3977 has some posh smoothing circut in them or its busted

    sorry i cant help you with the other stuff... i bought my driver as a kit with the motors and power supply (24v)
