    Default stepper drive A3979

    Question: is there anyway to use the outputs to the motors from the A3979s to drive an additional higher output h-bridge. My controller works well, it's just under powered. I'm thinking of it as a preamp. All the signal shapes are correct, so just amplify them? Power these new h-bridges with the new 48v as well and voila I can drive bigger motors

    Any way? sure but the circuitry would be more complicated than using a h bridge driver chip to directly drive the h bridge of your choice
