Greetings all; I gave up on that crashomatic box, and went out and found me one of those Dell 745's with an Intel dual core running at 2.6GHz, and 4Gigs of DDR-2. But I couldn't move that drive, no PATA connectors on the mainboard. So I had to install fresh, which went rather swimmingly, taking perhaps a half hour after I'd put my only new SATA drive in it, a 2 Terrabyte Seagate I had more or less reserved for amanda's useage.
I of course installed some of my personal pets, like mc, sshfs, unclutter and synaptic. I let the package manager update aroun 350 packages including switching our repo to master-rt, and about mid-morning there was another update to the 2.8.0pre, which I automatically installed. But at that point I was still hacking up low profile brackets for the 5i25 and its p2 breakout. Getting that going, I was amazed that there was not a /home/gene/linuxcnc directory made by the installer! Is that a bug, or is that a function of running pncconf the first time? I got sshfs working, and copied the 5i25.zip over to the new box, unpacked that and installed the 2 files my 5i25 card needed. And installed boot.ko, needed to start Jon's pwm servo amp. And convinced amanda I needed to recover my /home/gene/linuxcnc tree so I had all my configs and gcode back. And I've been the last 4 hours trying to get the machine to succesfully home. I don't care how slow you set the speeds in the trajectory or axis# sections, it will throw a joint following error, either while cruising along at 10 IPM (last week it could move 70 IPM except for Z & it could do 45!) or in making the stop when a home switch has been hit. Its also moving some faster than any setting in the .ini file. Somewhere along the line it WILL throw a joint following error. On axis X, or axis Z. Latency test has been run, and the servo-thread jitter is about 40 microseconds. isolcpus=1 is in effect and working. Can this be an sms problem? Or is this something all aglay in the 2.8 development branch? What is the best way to switch it back to the current 2.7.0 & see if that fixes this? Thanks.
