A detail that in a decade or so, I hadn't committed to wet ram. My bad , Andy, so I fixed that, and restored the defaults for that file, but disconnected the link that disables the machine, so I could play a little. Down at the bottom of that file, at the net watchdog line, I disconnected estop-latch.0.fault-in from the watchdog label. And since the manpage says that ok-in must be true, I put in a setp to do that because it needs all three conditions good before it resets. I cannot find the left "power" button status anyplace with a halmeter. The iocontrol,0,user-request-enable, is not resetting the watchdog, and while you can dance on the power button, it will only stay off for a few hundred milliseconds. Something is turning it back on. I have now looked at the spi bus, all 4 signals, and its quite clean, with a baud rate of 32 megahertz! Its doing the clocking in 4, 8 bit bytes each time, but the latency wobble between the 4 byte packets is quite noticeable on the scope. I only have the z motor running, but its erratic, you can definitely hear the horrible latency, and creeping along at 3"/minute, it will take off and run about 4" as fast as can be, but the dro doesn't track it well. So, while the bus looks great on the scope, it is still making some errors. I think... It looks like I could put the 7i90 in 3.3 volt compatibility mode without a stray signal blowing the fpga. Even with the noise gone, the backplot may suddenly draw an angled yellow line 2 or 5 feet offscreen, and rarely now the encoder velocity will still report several thousand spindle revs for a second or so. Flip a coin for direction. Cheers, Gene Heskett -- "There are four boxes to be used in defense of liberty: soap, ballot, jury, and ammo.
