Thanks for the guidance! It was out of date.

@kroybal this will most likely be resolved by updating the bootloader on the 3HC.
This resolved my issue, when I updated the firmware and forgot to do the bootloader as well.
Appreciate the help!
I haven't seen any information on resellers/forum posts about the duet magnetic filament monitor. Although I did see that someone was attempting to make a DIY which I must confess, I have considered doing the same.
Preferably I would rather purchase two, Is there any ETA as to when they will be restocked?

Seeing that it is a professional commercial printer i won't say that requirements are not met and also you should really come in contact with the manufacturer to, at least, get the basic configuration they use for this machine.
Well I got a hold of Aon finally, apparently they're updating their calling system. Anyways, the support team said that the M1 model is mostly a prototype for proof of concept. There are issues with the model, and there are success stories with it as well. They lined me up to talk to the machine's designer so I can get some answers on its anatomy. The support agent does not know a whole lot about their legacy machine, but she does know that the set screws used to tension the toolhead to the belt wiggle loose over time and that was one of the design updates they did going into the M2 model. That said I'm going to tighten screws where I can and see if they help control it from shifting. But based on the nature of the shifts it doesn't stand out as being mechanical slipping as much as it could be configuration.
We'll see. I am just happy to have talked to an Aon team member.

@kroybal hmm but why 15 ? If you have just a 6hc+3hc shouldnt it be address to 1 ? Or im missing something here
Addressing is arbitrary right? I certainly do not have tons of boards and channel 1 is free but I found it easiest to just flip them all to on in one motion instead of trying to be precise with flipping one switch.
Edit: Not totally arbitrary, but no right or wrong answer as long as its logical
I wasn't present to witness the cause of failure during the update that erased/corrupted its firmware. Which would be interesting to know and of course it was the temp's last day here at the lab (I am sure he feels bad 
, good kid).
If anyone knows what could cause a firmware flash to render a board unresponsive I would be interested to know.
However, I followed the erasing procedure and and using Bossa I was able to flash the most up to date firmware. Wired the machine up and printed a benchy boat just fine. Which makes this a resolved topic.
Thanks!
I have updated the firmware for the MB and TB's to the recent release about a week ago, that said I can rewire somethings and see what results it'll produce. I am still waiting to hear back from the machine's designer to ID the motors so that I can specify current ratings in the config.
The support team over at AON have been really delaying getting back to me. However, my boss went ahead and ordered a duet EX3HC. The results were excellent right out of the gate. All of the layer shifted existed on the x-axis which at the time was powered by low current channels 
. At any rate, I have new issues to uncover and fix but for now I will call this a victory. I will start a new thread in regards to complications I face with the expansion board.
Thanks for everyones help and suggestions, ultimately it led to discovering a trivial mistake.
UPDATE:
I got the switches running. I will probably just recognize only one of the redundant switches, since they seem to be coplanar and serve no obvious purpose. I am working with some juiced up motors for the z-axis and the only reason I can think of for redundant switches in to be safe not to damage the machine in the event of a signal failure.
I could post a photo if you are interested however, doesn't seem to be necessary at this point!
Thanks for your help.
This issue was resolved for those who experience a similar issue... I had my hotend heater mapped to a toolboard using pt100 sensors on the mainboard. Some rewiring and swapping pins around was in play.
