Here are the files, axis are not tuned only tested for basic motion.
I added Ferrite cores to the UVW of the spindle, checked all wires are grounded properly. They are all foil wrapped with drain. All drains are grounded. I even moved the EMI filter and VFD to as far away as I could (6 feet) without having to completely rewire. Same issue if I turn off the VFD breaker the M3 command holds with no reset, with the breaker on it resets in a second or 2. I removed the xboxctrl.hal but included it here. 
Thanks for all your assistance.

Does the machine and PC have proper grounding?

Looking at the hal file, I would suspect the estop input so you might try adding:

setp hm2_7i96s.0.inm.00.input-06-slow true

(the noise may also affect the other inputs so you might try with all)

Yes. I don't always trust over seas items so even if they don't have a ground lug they are grounded. All wire has grounded drains, 7i96s frame ground, emi filter, spindle, machine frame, stepper drivers are all grounded to earth ground

ok there is a freight train at the end of the tunnel!
It worked sort of. Not stable but it did show what is happening.
I put the setp on all inputs.
The EStop I now see toggles which it should not. The EStop is not actually wired yet and will be normally closed so there is always a 24V. Would this stop noise? The limits send 24V when detected but the spindle is not running. Will a limit triggering while operating cause any issue?

Yes, limits triggering will also cause a fault and change to machine-off state.
Maybe a wiring issue with the input common, or just limits/estop wired
near power signals.

Found another problem that seems to have fixed it. The machine is manufactured in the east, the input switches/buttons go through a wide metal clamp that I assumed was frame grounding the shielding of the wire, it was not. When I earth grounded the shield with the setp suggestion the random EStop trip seems to have stopped. It will take more tests to be sure.

Input common is Negative on the 24v PS. Limit switches are inductive and signal 24v when tripped, EStop will be 24V normal, 0V when triggered.
