So have I Reco. And I just got done building a raspian buster image with a 4.14.91-rt-v7 kernel, which is a step backwards from the 4.19.50 non-rt kernel that the zip comes with. But the build ended doing quite a few things I not seen it do before, including printing a big success in green text. So despite the fact that I really need to fork the rider and demolish 7" of grass, I'm going out to Wallies and getting two more 64GB PNY brand cards and I'm going to burn that image, then mount it and nuke what screwed me out of 4 days of my life so it can't do it again, and install the network configs from this card, then take it to the pi and boot it. Then comes the real fun, building linuxcnc on buster. That may take some coding skills I don't have as I am told buster has removed some stuff that linuxcnc needs, probably older python stuff. Some of linuxcnc dates back to before linux even, since what it is, is the growth of a NIST project to update our countries manufacturing machinery so as to remain competitive with the progress the rest of the world was making after WW-II. So the history goes back a long ways, governed by NIST rules about public domain but gradually rewritten in clean rooms so the much better protections of the gpl and lgpl could be applied. So while its close to 60 years old now, it is still under active development as new machines using different tech come online, often with poorly written proprietary software, but we have interfaces that can drive 90% of then OOTB. Sometimes at 10x the speed the OEM drivers could do it. And usually adding to the list of things the machine can do, none of my machines need to change gears (they don't even have gears unless the spindle is multispeed) to switch from inches to mm's, and all of then can drive a tap into a hole at exactly the taps pitch, then back it out of the hole by the same rules. A $30 carbide 4-40 tap has at one makers site, tapped around 40,000 holes with no noticeable wear, in 1/8" alu plate simply because its being used correctly. That old bridgeport mill was never made to do that, works great when the screws have been replaced with ball screws turned by motors controlled to the micron by linuxcnc. But I digress, so I'll play an Andy Capp and shudup. Cheers, Gene Heskett -- "There are four boxes to be used in defense of liberty: soap, ballot, jury, and ammo.
