Greetings all; I did find one or 2 more places I could reduce the noise with. I stuck a 17" piece of the wide tinned braid to the single point ground and found that connecting it to one of the pi's usb sockets with some suture clamps helped a bit, as did several of those tear off a wire and plug it onto a pin, in this case any of the p1-p2-p3 ground pins, all clamp to this same hunk of braid. But nothing could completely nullify it.
So next I duplicated 2 more minmax modules so I could watch the xz axis's which also suffered even when the spindle vfd wasn't powered up. And rigged them all to the flood button for a reset. Then the watchdog bit but because I'd broken the path, it did not disable the machine, and the pwr led on the 7i90 stubbornly remained the only one lit. And it continued to run the motors I did have hooked up. So something is lieing to me, just like a glued down rug. Now I am trying to cobble up a reset but I've run into something I gave up on once before. Namely that hal apparently has no clue what the hell to do with a pin that is supposed to be a bi-directional pin according to the message spit out when the watchdog bites. That says I should drive that bit false to re-enable the 7i90. But I have only seen that led on once, months ago. And show config, when I try to setp the pin, setp complains the pin is held high by another signal and it cannot access it to set it. Why? My thanks to anybody who can help me.
