Seems like you are sorting through it, but just to also spread the word, I grounded my Makita router to avoid ESD related disconnects (write up topic shown below). Haven’t had issues since then, but I also had major static buildup from my shopvac / Suckit dust boot and I don’t use it any more for the time being. I just vacuum by hand as required and carefully avoid touching the machine with the vac nozzle. I’ve not given up completely, its just that I’m moving soon to a more humid climate than the super-dry and cold air currently in Colorado, so I’m just ignoring the problem for the time being.
This might be a silly one, and I don’t know if it will work but what if you try an anti static band like this:
It might not work but they are a couple of bucks from a diy store.
If it doesn’t you can get special anti static dust hoses specifically for this application - it has a metal core running through and on dysons is standard…
I’d looked at some “central vac” hose in the 2" OD range in the past, I think that’s got a metal coil as well…
I’m wondering if I shouldn’t just cut to the chase and move my CM board unit away from the machine. If that didn’t mean splicing in about 50 wires, I’d have done it from the getgo. cough cough @WillAdams the carbide store should totally sell just the extension cable kits separate from the full upgrade kits CooughCough

Ha ha, that be a great idea. I had to extend 2 motors when fitting drag chain. Nothing like sewing and soldiering 16 wires then heat shrinking each connection…

Alright, update time:
As mentioned, I sucked about 10’ of stranded copper up into my dust hose, then grounded the end to my spindle.
Last night I ran a ~2h job, involving lots of on/off of both the vac and the spindle and had NO grbl crashes. I’ve got another job to run this weekend of a similar length and I’ll test again, but I’m calling this goblin vanquished for now.
Thank you ALL for the help, specifically on grounding the hose - I wouldn’t have thought of that.

Glad you got this figgered out. Weird that the goblins are all different.
I initially grounded my vac hose with copper wire through the entire length, as well as the router body. But, the wire in the ground hose proved a problem in that it caused clogs in the hose. I use the same hose for vacuuming the floor, some of the stuff that gets sucked up during that can be much larger then chips/dust from the SO3. Soooo, on a 4-clog day I got…annoyed and yanked the wire out. That was many jobs ago, still zero interrupts. Go figure.
