Mach doesn't know or care what drives you use it just sends pulses to the drives based on your preferences in motor tuning.
You'll see a difference between digital and Analogue drives but it will...

Measuring it at a random time is pretty meaningless - at any one point on the grid the mains voltage can and does vary by several volts over time. I'd advise getting a transformer based on the...
