If you are designing new electronics, then Arduino Mega and L298 are both bad choices. The Mega is underpowered, especially when controlling a delta printer, and 32 bit processors are cheap these days. The L298 uses ancient bipolar technology resulting in high power dissipation, and in order to work in constant current mode (which is necessary to get good speeds) it needs another chip (the L297) to driven it.
With Arduino Mega, which stepper motor driver do you suggest me?
