Now that's just opened a whole new can of worms, lol, Servo Motors and Drives!? so from my quick Google they definitely seem like they're the best, but I have even less of a clue about these... you say I don't need a DC PS for them, so are they just hooked up to 240v?? I had a budget of around £150 for each Closed Loop Motor and Drive, so if I can get Servo Motors and Drives for similar I might just go for them, I'd need 4 as my Y-axis is slaved. You say 1kw Servos, are they not sized like normal Steppers, ie Nema23, Nema34, etc..?? I'll get on Youtube and check them out...
