Sorry. I think we were talking over each other. I don’t think it will make any difference which one is on there if it is still failing.
Also sorry if Ryan and I are being skeptical. It is weird that it was working and now, this symptom is showing up that appears to be completely physical. It would be a shame if it was something simple like a metal chip shorting the pin or something.
That’s okay, I understand. I’ll remove the board again and use some air to blow it off - top and bottom.
The problem is MUCH worse, then longer it runs. If I pull the power for a long period of time, then reapply, the problem takes a good 10 mins or so to crop-up. Once it does though, it happens consistently at every boot. That’s the condition it is in right now. I can pull the power for 10 seconds, then it boots up immediately to the problem.
After removing it, blowing it out. It took about 5 minutes for it to halt.

@vicious1, reading the fine print, the board had a 30 day guarantee. I’m happy to buy another one to get running again. I’m going through withdrawals already. If you have it in-stock, I’d like to order for local pick-up, if you don’t mind.
It’s very possible that the loose power connection that I identified in the first-place, caused some electrical damage.
Just a shot in the dark, are the stepper drivers overheating? How does the overheat protection circuit work when they do? Do they signal on the kill pin? I know it’s more questions and no answers. Just a thought after looking over the thread.
The steppers aren’t connected. The board goes into the halted condition with only the display connected, or only the USB connected - with two different power supplies.
That is a bummer. I am out of ideas.
I’m ready to buy 
@vicious1 check your email
@jeffeb3, I truly appreciate the assist from you and @vicious1 . The day isn’t a total loss. Instead of cutting fun things for my friends and family on the CNC, I built some sorely-needed storage in my garage.
Huh, definitely a first.
Since we can’t do anything tonight (gotta clean up and do dinner and clean that up as well). Try one last thing. Fresh platform io flash and then use the LCD to initialize the eeprom. It is in the menus under config, then advanced, all the way at the bottom.
Definitely a first if this is actually bad, this has happened before here, a lot, but using arduino and the wrong ug8lib. Platform io should not have that same problem. Let me know tomorrow if it didn’t work for the millionth time and we can do a quick swap.
I’ll give it a go tomorrow when I get a break from work. Thanks again!
Working in construction and seeing your storage shelving, I have to mention something as I’d hate to see anyone get hurt. The vertical framing members are not adequately fastened to hold substantial weight. The nails will split the end of the stud with very little weight actually. I recommend instead using some thick galvanized wire with proper carriage bolts and perhaps even hardware strapping for the vertical members. The wire will hold hundreds of pounds tension, and carriage bolts with strapping will adequately spread that load to the joists above and your horizontal framing below.
Cheers… off to work,
Kev
@vicious1 - Is a “Fresh” flash any different than just flashing it as-per your published directions?
@truglodite, thanks for the tips and looking-out for my safety. Those aren’t nails though. They are 3" #10 deck screws. I am able to grab those cross-members and hang my 240 lb body from each of them. That, plus the bracing on the wall should support a minimum 720 lbs. FAR more than the 50-100 lbs that I plan to put up there.
nope
I’d at least add some 2x4s horizontally under the front edges. That plywood will bow over time.
Ok. I flashed it again, then reset the EEPROM then let it sit… Same problem. I’ll exercise the plan that we discussed in email.
