[18:36:21] <Wolf_> figures seeing that I have cash in hand to get something in that price range lol
[18:36:33] <malcom2073> Heh
[18:36:42] <malcom2073> I see matsurras going for 1000-1500 at random auctions
[18:36:44] <malcom2073> Working ones
[18:36:48] <malcom2073> Very similar mill, slightly larger
[18:36:59] <malcom2073> 9000lbs, and 8+ ft tall
[18:37:30] <malcom2073> My last job at a matsurra 500, nifty machine, I'd like one
[18:37:33] <malcom2073> skunkworks has one
[18:37:56] <Wolf_> moving that wouldnt be a issue, getting it in the shop on the other hand..
[18:38:30] <malcom2073> haha
[18:38:38] <malcom2073> Install a comealong boltdown in the floor
[18:38:40] <malcom2073> drag it off
[18:39:00] <Wolf_> the doors are all 8’ tall
[18:39:34] <malcom2073> It'll be under 8ft if you remove stuff from the top haha

[18:47:28] <c-log> JT-Shop: Today's Log http://tom-itx.no-ip.biz:82/~tom-itx/irc/logs/%23linuxcnc/2016-12-27.html
[18:47:37] <pcw_mesa> lunada: if you have differential encoders there are many many more wrong than right ways to wire them
[18:47:50] <JT-Shop> index
[18:47:50] <c-log> JT-Shop: The #linuxcnc index http://tom-itx.no-ip.biz:82/~tom-itx/irc/logs/%23linuxcnc/index.html
[18:50:29] <JT-Shop> https://www.youtube.com/watch?v=brjGl3sp7co
[18:51:08] <pcw_mesa> and many of the wrong ways will sort-of work
[19:02:22] <lunada> pcw_mesa, hmm well i wired them all the same via the schematics of the machine builder and the 7i77 datasheet.
[19:02:47] <lunada> i'll double check though
[19:02:56] <CaptHindsight> https://imagebin.ca/v/2vCyJwwBDMuC I have to move this Matsuura in a few days
[19:03:40] <lunada> how far?
[19:03:49] <CaptHindsight> miles
[19:04:33] <lunada> 14klbs?
[19:04:50] <CaptHindsight> yeah, around that 12k
[19:05:33] <lunada> i usually have a guy with a flat bed tow truck put it on skates and winch it up on the tilt bed
[19:05:41] <lunada> and remove it the same way
[19:06:16] <lunada> i've done that with roughly half a dozen machines now, some even bigger than that
[19:06:22] <CaptHindsight> I have a 16k forklift as well, but it will go up and down a tilt bed
[19:08:12] <lunada> it looks narrow and top heavy like my lagunmatic
[19:08:32] <Tom_L> CaptHindsight, puttin that in your garage??
[19:09:02] <lunada> better be a tall garage lol
[19:09:41] <CaptHindsight> Tom_L: moving
[19:10:52] <Gaston|Home> pcw_mesa: I found a tempting Mini-STX motherboard with 2 builtin nics and 1151 socket. http://www.newegg.com/Product/Product.aspx?Item=N82E16813132897 With a G4500 I bet it will fly
[19:12:28] <Gaston|Home> with a case it comes out marginally more expensive than the zotac http://www.newegg.com/Product/Product.aspx?Item=N82E16811163360
[19:14:50] <CaptHindsight> lunada: 21ft ceiling
[19:16:15] <lunada> nice
[19:35:50] <pcw_mesa> Gaston|Home: I have G3258+H97 MB (about the same as the G4500/H110 but a generation older) and its really fast and has great latency
[19:36:20] <pcw_mesa> probably 2x as fast as the Zotac
[19:37:37] <Gaston|Home> Sounds promising and still not too expensive. I guess it's no guarantees but it seems other have managed to get things running using newer kernels so I think I will order something similar to play with.
[19:37:49] <pcw_mesa> lunada: if they are differential encoders check with a DVM _across_ the A,/A B,/B Z,/Z
[19:37:54] <Gaston|Home> Should make a nice set-top box if all fails :)
[19:38:37] <pcw_mesa> Yeah Skylake may be a bit leading edge for Linux
[19:40:33] * Gaston|Home checks if the pillow still loves me
[19:40:39] <pcw_mesa> lunada: at various encoder positions you should get about -3 or +3 measure across the pair but never anything between these limits
[19:41:09] <pcw_mesa> s/measure/measured/
[21:03:46] <pink_vampire> what is the path for the axis.py?
[21:12:49] <pink_vampire> i can't find the file
[21:14:26] <pink_vampire> maybe it exists as under different name?
[21:14:40] <pink_vampire> i'm using the debian version.
[21:16:34] <roycroft> find / -name axis.py -print
[21:17:12] <roycroft> if it's a big machine with a lot of files that might take a while
[21:18:31] <roycroft> if it's just a turnkey linuxcnc machine it should complete pretty quickly
[21:22:28] <archivist> also locate axis.py
[21:22:55] <archivist> in a database and fast
[21:25:59] <pink_vampire> I tried locate..
[21:27:12] <pink_vampire> find / -name axis.py -print didn't give any output
[21:27:14] <roycroft> locate won't necessarily work
[21:27:26] <pink_vampire> roycroft: archivist
[21:27:45] <roycroft> locate is based on a database that needs to be rebuilt periodically
[21:27:52] <roycroft> usually a nightly cron job updates the database
[21:27:59] <roycroft> and it does not search the entire machine
[21:28:04] <roycroft> just certain directories
[21:28:14] <pink_vampire> I even tried to use tree / > /home/file
[21:28:29] <roycroft> if my command returned nothing then that file does not exist on your machine
[21:28:32] <pink_vampire> and then cat file | grep axis.py
[21:28:38] <roycroft> which would explain why you cannto find it
[21:28:43] <archivist> look in usr/share
[21:29:03] <roycroft> if the find command failed it is not in /usr/share or anywhere
[21:29:45] <roycroft> i would normally add the caveat that the user must have permission to walk every directory on the machine
[21:29:56] <roycroft> but since there was no output, i'm assuming the command was run as root
[21:30:11] <pink_vampire> I run the find command as root
[21:30:13] <roycroft> as unreadable directory names would be spewed to stderr
[21:30:22] <roycroft> and thus there would be output
[21:31:07] <pink_vampire> roycroft: are you using the debian version?
[21:31:19] <roycroft> i have it installed on wheezy in a vm
[21:31:30] <roycroft> if you want me to see if the file exists there i'll check
[21:31:38] <roycroft> let me fire up the vm
[21:31:46] <pink_vampire> thanks!
[21:31:51] <roycroft> it's 2.7 on wheezy
[21:32:12] <pink_vampire> i'm using 2.7.8
[21:32:21] <pink_vampire> roycroft: ^
[21:32:38] <roycroft> nope
[21:32:41] <roycroft> no such file
[21:33:09] <archivist> just plain axis
[21:33:09] <roycroft> looks like i'm running 2.7.0
[21:33:42] <roycroft> find / name "*axis*" -print | less
[21:33:46] <roycroft> you'll get a lot of hits there
[21:34:42] <pink_vampire> too much
[21:34:58] <roycroft> /usr/bin/axis is a python script
[21:35:09] <roycroft> is that what you're looking for?
[21:35:33] <roycroft> file /usr/bin/axis
[21:35:47] <pink_vampire> I think i found it!
[21:36:17] <pink_vampire> why it without the .py?
[21:36:22] <roycroft> why not?
[21:36:26] <roycroft> it's shorter to type
[21:36:37] <roycroft> and unix is not retarded like windows
[21:36:46] <roycroft> it doesn't require a file extension to know what kind of file it is
[21:37:10] <pink_vampire> what about readability?
[21:37:17] <roycroft> what do you mean?
[21:37:24] <roycroft> you can read /usr/bin/axis
[21:38:00] <pink_vampire> but it look like a path to a folder named axis, not to a python file..
[21:38:28] <roycroft> no, it's an executable script
[21:38:53] <roycroft> ls -l /usr/bin/axis
[21:39:12] <pink_vampire> I know...
[21:39:49] <roycroft> if it were a directory the permissions would start with a 'd', not a '-'
[21:41:32] <pink_vampire> but it is much more convenience to use the .py extension on the file..
[21:41:51] <roycroft> so you can type 75% more characters every time you run it?
[21:41:55] <roycroft> if you insist
[21:41:57] <roycroft> cd /usr/bin
[21:41:59] <pink_vampire> and the docs point to the axis.py..
[21:42:01] <roycroft> ln axis axis.py
[21:42:11] <roycroft> now that's a valid complaint
[21:42:33] <roycroft> if the documentation is wrong then you are right to complain
[21:42:41] <roycroft> and let the documentation maintainers know that it's wrong
[21:44:49] <pink_vampire> anyway.. to rename one of the mains files in linux cnc without any notice it's annoying.
[21:45:57] <roycroft> so in the second fine command i gave you
[21:46:37] <roycroft> you were searching for a regular expression
[21:46:43] <roycroft> * matches any character
[21:46:55] <roycroft> so you were searching for any file that contains the string "axis"
[21:47:21] <roycroft> * matches zero or more characters, i should say
[21:47:41] <roycroft> if you're only looking for executable files
[21:47:56] <roycroft> find / -type x -name "*axis*" -print
[21:48:19] <roycroft> if you're only looking for executable files that are not directories
[21:48:26] <roycroft> find / -type x -type f -name "*axis*" -print
[21:48:44] <roycroft> find is one of the most powerful commands on a unix system
[23:01:51] <MacGalempsy> evening gents
[23:12:24] <rue_house> if randyg is here, could you msg me?
