Anyone have any experience with paralleling the stepper motor outputs to drive a larger than normal stepper motor? I realize that the L298D chips are rated up to 0.6mA per coil, and that piggybacking them can get you a bit over an amp; but has anyone tried wiring a motor to both outputs in parallel? I realize you would have to be very careful in the code to drive both outputs exactly the same, but is there any fundamental reason you cannot or should not do this?
Granted, it might be better to just get a board that was really rated for the motor in question, but if all you had was a Motor Shield and wanted to make do...

Re: Parallelling the Motor Shield stepper outputs?
The problem with doing that for steppers is that the PWM for M1/M2 and M3/M4 are based on different timers. You could probably make it work for single-step mode, but not for microstep.
