Hello Tom,

I am installing a KSnap with dual SnapAmps.

I have Both X, and Y axis going with step response.

I have been fighting with power supplies trying to use the old one..

In the meantime, I have a 10 Amp 30 V supply that I have been using to power the amps one axis at a time.
When I look at the Analog screen for the X and the Y, Channels 0 and 2, on SnapAmp0 I see the 30V displayed as expected.
When I have the power hooked to SnapAmp1 Channel 4 for Z, I am only seeing about 19 volts or so and the unpowered axis on SnapAmp1 shows 2.9 or 3.0 V instead of the 1.1-1.6 that normally displays when there is no external power.

It is possible that SnapAmp1 saw 100V briefly on its input connector when old power was first hooked up. Could that have blown something and be the cause of this?

Thanks and Happy Holidays!

Jake
