Hi! I'm searching the best driver (performance/cost) to use for my stepper motors, that are 4.6a, with 8 wires coming out, so i can drive them in every way. I'm searching something with microstepping capabilities, and i want to drive them with a ~70vdc supply.
I'm quite pratical with electronics, so also a DIY way is well accepted, but i prefer a complete schematic, i don't want to bother to project nothing, only build solder and and drive, for sure i can do pcb myself.
What do you suggest?
Really thanks to all!
