Easy Servo Drive?

[Tenson]

I guess the parallel port was never really intended for time critical applications.

I ordered the ethernet easy stepper (ESS) from Amadeal last night and they already shipped it! I can't afford any down time on my machine for some weeks so I will have to try it out later on.

I also bought an 80V driver for the X axis that matches the ones on the Y axis. I'm sure it doesn't make much sense to run Y axis on 80V and X axis on 50V as I currently am.

How big a PSU do you guys usually run for Y and X axis? Currently my Y axis is powered from a 500watt toroid with 10,000uF smoothing caps (no SMPS here!). I wonder if it has enough headroom to power the X axis too, or if I need to get an additional PSU. A basic electricity meter shows my machine draws about 250watts for both Y and X together under normal use, but the meter will not show peaks (then again PSU caps should supply peak current draw).
