If I am going to add in another PSU, should I try and increase the voltage? I cant see the exact number, I cant find these drives anywhere - but lets assume it will take 48V DC. I also need to check if the current settings are correct for the specific voltage. Currently everything runs off a 24V 10A supply.

Would it be 'good practice' to try and get the voltage as high as possible?
Have you tried running the lathe with a voltmeter (an oscilloscope would be better) on the powersupply to see how it's handling the load?

If you were getting good enough performance with 24V, I probably wouldn't be inclined to bump it up that much. I'd probably aim around 30-40V, but it would really depend on what the motors could handle. Remember higher voltage just means better performance at speed. At low speed it won't make much, if any difference.
