I studied the man page for nearly 2 hours trying to decode that obtuse SOB of a man page for sftp about 3 weeks ago, gave up and asked on the ubuntu list how to make nfs work. I had an answer that worked in half an hour, but since then all 3 machines have been rebooted at least twice, and nfs is DOA. Again, for the 5th or 6th time in 10 years, I've made it work about that many times, but its gone again in 30 minutes. I used to use samba for that stuff, but Tridge broke it about 3 years back, so its been about that long since I was able to use samba for this stuff. The nfs manpages, what there is of them, all talk about doing it in /etc/fstab, the authors of such drivel conveniently and completely oblivious to the fact that one miss-typed character in /etc/fstab, and the machine will not boot from anything but the install cd, where you have to mount the drive with etc on it, then use some damned editor (nano/pico?) you have only used 3 times under duress to fix it. If you can figure out what needs fixed... Not your fault at all Jon, but when you have your own private local network, with the same install from the same cd on all 4 machines (there's a lappy in this mix too) there is absolutely zero excuse for making it so damned difficult that its easier to get dressed, grab a usb stick and copy what you want to move to it, grab the stick, bring it 100' back down the hill and plug it in here, only to find the first thing you have to do is issue as root, a chown -R gene:gene /media/keyname/ command because for some reason gene on shop, gene on lathe, and gene on coyote, while I am the default sudo enabled first user #1000 on all 4 boxes, still don't have perms to read the ^% files! What the heck is the diff, I own that file on all 4 machines! But after the chown, it works. So does mc, when nfs works, and that doesn't need the chown, it just works WHEN it works. So that is what I'll do right now in order to get the .hal and .ini files where they can be read by you folks to see where I screwed up. With good luck, half an hour maybe. But my luck hasn't been that good the last 36 hours. I just made a 2nd shaft extension for that ball screw, and the last step, cutting a thread for a 5/16 18 tpi nylock nut for bearing adjustment, stripped the threads off the end section of because I can't get a 5/16 18 thread cut when there is a .177 thru hole for the differential screw access thru it lengthways. So I've gone scouting and have both 5/16 24, and 8mmx1.0mm nuts to try, which should give me another .020 of steel for wall thickness at the bottoms of the threads. Thanks for reading this far. Jon.

HUH? I use commands like sftp username@ip_address then, cd, ls, pwd, and finally get or put filename. it can't be any simpler than that! Of course, you need an sshd running on the computer you want to connect to, but that is fairly simple, too. I studied the man page for nearly 2 hours trying to decode that obtuse SOB of a man page for sftp about 3 weeks ago I can't understand the problem. you cd to the directory you want to pull or push files from, then make the ssh connection, cd to the remote directory and get or put the files. If you want to change the local directory, lcd, lpwd and lls do the local version of cd, pwd and ls commands. It works mostly like the cp command. There are a buch of more complex options, I avoid them. Not your fault at all Jon, but when you have your own private local network, with the same install from the same cd on all 4 machines Not a chance, I have Beagle Boards (ARM CPU), Ubuntu (6.06 up to 12.1), Debian, CentOS and some other systems here, they all work seamlessly with sftp. I occasionally send files to/from Sun machines and other non-X86 architectures and non-Linux systems, again, no problem with sftp. (there's a lappy in this mix too) there is absolutely zero excuse for making it so damned difficult that its easier to get dressed, grab a usb stick and copy what you want to move to it, grab the stick, bring it 100' back down the hill and plug it in here, only to find the first thing you have to do is issue as root, a chown -R gene:gene /media/keyname/ command because for some reason gene on shop, gene on lathe, and gene on coyote, while I am the default sudo enabled first user #1000 on all 4 boxes, still don't have perms to read the ^% files! What the heck is the diff, I own that file on all 4 machines! OK, well, there's one of your problems. NFS is a local files system on each node, and you MUST coordinate file owner IDs across all the systems, or use proxies. sftp avoids that problem, as each end of the sftp session is logged into its machine, and files brought across get the local owner's permissions.

I do see the spindle P term set to 100, that may be too high for stable response. Since you are feeding velocity out of the encoder component, it will have a lot of fluctuation due to the sampling. Somebody, I think Andy or Peter, suggested using the filtered velocity output from the encoder component at least for the closed-loop velocity instead of the raw velocity output. It won't help for the spindle-synched axis, though.
