I bought all those from Jeff at Xylotex, 3 ea of the 262's he had originally, then bought a 4 axis kit with 425's when I needed to add a 4th axis. And 6 amps might be what the 425's need when wired parallel. They are 8 wire, in series & currently getting about 2.35 amps/phase. The 425 motor on the Z drivers ios the only 425 installed ATM, and could do more than that 2.37, but ISTR I had them set for 2.4 amps/phase when I cooked the 4 axis Xylotex board so as that seemed sufficient, I set the new MM-542's for about that same (2.37) amperage. The 262's are sometimes called a double stack as they are long, and the 425's are often called triple stack because they are even longer. I have to open my new drivers box up, as the A axis is running at 100% current full time, one of the dip switches must have gotten bumped, but when I do I may as well set them all up to 2.84 amps. They can go to 4.2 amps, but that may demag the rotors I'm told. But with 20 tpi XY screws, I doubt I'll gain any advantage in rapids. I am pretty well voltage (28) and rpms at that voltage limited. A 36 volt supply would help but those are generally make it yourself, with 3x more in parts than I have in the 28 volt switcher with 5 & 12 volt low current outputs in there now, about a dollar a volt from All Electronics.
