I will keep you posted. Parts won't be here for a couple weeks.

Is there a switch on the Acorn power supply to change it to 220 volts?

Tuffduck, you know Google could answer this question for you. 
From the Meanwell website:
Input Voltage (V)
110/230 universal input
88 - 264
As always, I would unplug from the Acorn and check the output voltages from the power supply the first time I plugged into a new voltage source that was different from what I had been using.

I have the 110 volt line removed and the acorn power supply changed to 220volt. Installed EMI filters.

Did you install a ground buss bar so everything is grounded in the same place? Hopefully you’ll get your db25 break out board soon to finish up the maintenance in your system.

The ground buss shoul be here tomorrow.

Installed the ground bus today. Just waiting for the card and will clean up some of the wiring as well.

Make sure your electrical panel is up to par. I've seen many machines do weird things all because it either wasn't grounded, neutral and ground weren't properly separated or the ground was broken or unreliably attached. "Oh, it's just ground...break off the prong"
My advice would be to really have a good look at your electric feed and check continuity from the panel ground (ground rod) to your control box ground. (Set meter to continuity with a long jumper wire)
Plugging in a UPS (Uninterruptible power supply) can help to diagnose shoddy electric because the internal battery smooths out noise and spikes/dips. You might try borrowing one if you can for testing. Make sure it's big enough. I literally just went through this last week. Customer's building didn't have a single ground on the 2nd floor where machine was located. Servos used ground as voltage reference. All kinds of weirdness ensued. A word to the wise...
