[00:03:01] <t12> heres a cool one
[00:03:01] <t12> https://www.sbir.gov/sbirsearch/detail/871781
[00:03:15] <chupacabra> did some water testing but that is way over my head
[00:03:58] <chupacabra> hindsight where is stuff i can bid on?
[00:04:22] <CaptHindsight> chupacabra: work or machines?
[00:04:25] <chupacabra> i gots an engraving machine
[00:05:04] <chupacabra> work. i got machines lightweight
[00:05:33] <CaptHindsight> dunno
[00:05:34] <t12> https://www.sbir.gov/sbirsearch/detail/870127
[00:05:46] <CaptHindsight> anyone going to CES?
[00:05:49] <chupacabra> i was almost dead 4 years ago. Im going again
[00:05:55] <t12> fast set runway repair goop contract
[00:07:00] <CaptHindsight> ooh thats an easy one for me
[00:07:24] <chupacabra> i have a 3d printer too
[00:08:17] <CaptHindsight> $30/lb might be out of their budget

[00:09:44] <chupacabra> we way off topic
[00:09:57] <t12> i'm lost in an sbir-trap
[00:10:09] <CaptHindsight> heh, anything is fair game this time of the day :)
[00:10:17] <chupacabra> keep it to yourself
[00:10:31] <chupacabra> oh really?
[00:10:38] <CaptHindsight> t12: any projects for chup?
[00:10:50] <t12> what kinda stuff
[00:11:04] <t12> https://www.sbir.gov/sbirsearch/topic/current
[00:11:07] <t12> the list goes on forever
[00:11:14] <chupacabra> im caught in making female forms in 3d printer
[00:11:26] <t12> enemy distraction forms
[00:11:52] <chupacabra> females are not the enemy
[00:12:09] <CaptHindsight> time to wind down, hasta banana

[00:29:02] <t12> heres a linuxcncish one:
https://www.sbir.gov/sbirsearch/detail/870371
[00:48:31] <t12> heres a good machining one:
https://www.sbir.gov/sbirsearch/detail/870671
[00:50:42] <chupacabra> 4 axis pcb boards? I'm sure Schlumberger wants some
[00:51:09] <chupacabra> round for downhole
[00:52:49] <chupacabra> darn i remember having to run the panograph by hand. this cnc stuff is the life of riley
[00:54:12] <chupacabra> watch tv and listen to feeds and speeds
[00:55:19] <witnit> t12 that one with the grinding blades
[00:55:25] <witnit> got any ideas for that?
[00:55:45] <chupacabra> building new yoda on 3d printer. Selling for 20.
[00:56:03] <t12> i think that would look like
[00:56:11] <t12> workhold turbine blade
[00:56:30] <t12> laser surface scan -> software -> toolpath generation -> run grinding
[00:56:40] <t12> in some multiaxis cnc grinder
[00:57:08] <paulliebenberg> Hi, looking for some help calibrating a usb touchscreen, 2.7 wheezy. it’s already been a long night!
[00:57:13] <chupacabra> i use carbide mills or a single non rotating diamong=d
[00:58:00] <chupacabra> fuck touchscreen in debian. i gave up on that in 1999
[00:58:09] <witnit> the real trick would be to create a specialty on site robotic probe grinder which manages the grinding while the turbine is on the engine :)
[00:58:37] <paulliebenberg> so ubuntu?
[00:58:50] <paulliebenberg> tried mint for a while
[00:59:42] <chupacabra> sucks but may as well get linuxcnc cd and install it.
[00:59:58] <chupacabra> i prefer Fedora myself
[01:00:27] <chupacabra> its just a machine I keep telling myself
[01:00:31] <paulliebenberg> yeah, thats what I did, cd is debian now
[01:00:47] <chupacabra> works well
[01:00:53] <paulliebenberg> i feel like crying already.
[01:01:11] <chupacabra> You know Ian commited suicide last week?
[01:01:16] <paulliebenberg> what works well, fedora?
[01:01:50] <chupacabra> i cant finagle fedora to work even compiling source
[01:02:00] <paulliebenberg> ?
[01:02:17] <chupacabra> ian of debian
[01:02:24] <paulliebenberg> so what are options for touchscreen?
[01:03:36] <chupacabra> i was touch expert. got it working for POS stuff. What touch you got? should just work in fedora
[01:04:20] <chupacabra> Damn thinking back i was rich for 5 years with touch bs
[01:04:35] <paulliebenberg> it is a 3m, but I want to run a machine with this screen.
[01:05:03] <chupacabra> and its hooked to a debian machine
[01:06:08] <paulliebenberg> yes
[01:08:11] <chupacabra> i wont help. sorry
[01:08:43] <chupacabra> cant really. fuck debian
[01:09:07] <chupacabra> hint kernel module
[01:09:12] <paulliebenberg> ok, thanks I guess!
[01:09:57] <chupacabra> did you get the part about ian killing himself?
[01:10:54] <chupacabra> maybe debian will go away now
[01:11:17] <chupacabra> he divorced deb years ago
[01:16:24] <anomynous> can i undo what i just did in aptitude? ;D i installed a bunch of stuff i dont want, really.
[01:18:00] <chupacabra> aptitude remove
[01:18:07] <chupacabra> maybe
[01:18:27] <anomynous> a whole bunch of dependencies i didnt want
[01:18:30] <chupacabra> dnf remove in fedora
[01:19:05] <chupacabra> if you have hard drive space who cares. wont be used
[01:19:16] <anomynous> i have a 4gb flash
[01:19:40] <chupacabra> i remember when that was huge
[01:19:47] <anomynous> me too
[01:19:56] <chupacabra> a sd drive?
[01:20:00] <anomynous> can i extract logs with installation times?
[01:20:05] <anomynous> kinda
[01:20:10] <anomynous> rasperry pi
[01:20:21] <chupacabra> install on hard drive
[01:20:26] <anomynous> no.
[01:20:31] <anomynous> this is what i have now
[01:20:38] <anomynous> im not getting a hd for it
[01:20:39] <chupacabra> ahh im a pi guy too.
[01:20:48] <anomynous> besides hd is heavy and i have nowhere to put it
[01:20:55] <chupacabra> just havnt done more than tv
[01:21:25] <chupacabra> you got a pi zero?
[01:21:50] <anomynous> dunno
[01:21:51] <anomynous> its some pi
[01:21:54] <anomynous> bought used
[01:21:56] <anomynous> :D
[01:22:09] <chupacabra> pi zero is 5.00$
[01:22:19] <anomynous> could be
[01:22:32] <anomynous> i paid 20€ with case
[01:22:36] <chupacabra> i have first through b
[01:22:59] <chupacabra> gotta get a zero
[01:23:33] <anomynous> soo can i get installation log with install times to filter the packages and feed for aptitude remove
[01:23:42] <chupacabra> no parallel port for my cnc machine
[01:24:09] <anomynous> theres no adapters?
[01:24:23] <chupacabra> you got plenty of room
[01:24:30] <anomynous> i dont want that stuff
[01:24:50] <chupacabra> no, usb parallel doesnt have enough power
[01:26:26] <chupacabra> http://riecilla.com/node/3
[01:26:34] <chupacabra> my junk
[01:36:23] <witnit> chupacabra what is that complex part you have chucked?
[01:47:19] <anomynous> what is negative character group in sed? Ie [^abc] for matching anything but abc
[01:48:17] <Jymmm> ! (not)
[01:48:26] <anomynous> [!abc]?
[01:48:49] <Jymmm> if (bacon != eggs){}
[01:49:02] <anomynous> s/regexp/subs thing
[01:49:03] <anomynous> :D
[01:49:15] <Jymmm> Not sure with sed, just know negative is typically !
[01:49:20] <anomynous> ok
[01:49:28] <Jymmm> negate*
[01:50:03] <Jymmm> and you don't want to get me started on ternary =)
[01:50:28] <Jymmm> I love using nested ternary, really fucks with ppl too =)
[01:50:53] <anomynous> mm... a friend told me a tale about disassembling a 1000 chars long line of code. More of those.
[01:51:29] <anomynous> well, not exactly a friend. But a guy i know.
[01:52:10] <Jymmm> Eh, I think there are those that "get it", and those that don't see/understand that things are being implied. It's a foreign concept to them.
[01:53:09] <Jymmm> If (house on fire){fuck everything else cause we dont care}
[01:54:15] <anomynous> how about nested list comprehensions with some lambda functions in python? =)
[01:54:53] <Jymmm> Yes, I do have snake skin boots, thanks for asking =)
[01:54:57] <anomynous> :D
[01:56:43] <anomynous> btw cant you use python with linuxcnc? Like, even embed it with gcode?
[01:57:38] <Jymmm> I know there are O-code, but I'm not sure you can embed another lang
[01:58:20] <Jymmm> http://linuxcnc.org/docs/html/gcode/o-code.html
[01:59:32] <archivist> I hope gcode in all its peculiarities remains a snake free zone
[02:00:11] <Jymmm> I suspect that you could use python to generate gcode that is fed into lcnc directly though
[02:00:46] <archivist> its main silliness is the syntax around variables
[02:01:06] <Jymmm> It be funny to have scanner follow an ant crawling on the ground, and feed that into lcnc live =)
[02:18:02] <witnit> cant you run an ocode, modifyy the ocode on the fly and rerun it within an active gcode cycle without ever stopping the machine?
[02:18:28] <witnit> so basicly cant you modify ocodes on the fly
[02:23:54] <witnit> Jymmm: is this what you were meaning
http://linuxcnc.org/docs/html/remap/remap.html#remap:embedded-python
[02:24:34] <archivist> you can vary variables on the fly
[02:25:55] <witnit> like just stored parameters?
[02:26:30] <Jymmm> ocode can load files on the fly
[02:27:07] <Jymmm> witnit: like variables ($a = 122, $b = 11, etc)
[02:27:19] <witnit> I was thinking for some reason I was able to modify an ocode or mcode or something
[02:27:26] <witnit> while the program ran a repeat cycle
[02:27:31] <Jymmm> you can
[02:27:54] <witnit> and so I could change the distance it traveled between cycles or calls
[02:28:06] <witnit> but it was a bash file IIRC
[02:28:34] <Jymmm> as far as that "embedded python" link, it looks like that is the results of someone's experimentation of it at first glance, and above my paygrade to know how well it actually functions
[02:33:14] <Jymmm> Deejay: Yo
[02:33:18] <Deejay> moin
[02:34:33] <witnit> mojn!
[02:43:47] <Jymmm> "GoogleSoftwareUpdateAgent" is piking all over syslog, argh
[02:43:48] <witnit> is anyone building any standalone units that they are remotely controlling? so like an automatic boot and start/run .ngc?
[02:43:53] <Jymmm> puking*
[02:44:19] <witnit> headless or no monitor/keyboard/mouse builds
[02:52:13] <archivist_herron> never wanted headless, would be really silly to stand next to a machine and see a problem but to have to run to some other place to use the front panel
[02:52:56] <witnit> space enviornment
[02:54:36] <anomynous> networked multi-head system with automatic palleting in your garage
[02:55:42] <witnit> yes very similar :)
[02:56:03] <witnit> I have to do compact ridgid tapping system
[02:56:25] <witnit> I want each unit modular, yet interconnectable
[02:56:39] <witnit> 2 axis
[02:57:53] <Jymmm> I hope you have a LOT of BRB's!!!
[02:57:59] <witnit> brbs?
[02:58:48] <Jymmm> Big Red Buttons, a PROPER (non computer controlled) emergency stop for EACH station,
[02:59:02] <witnit> yeah each machine has a panelbox
[02:59:07] <Jymmm> at the very least
[02:59:07] <archivist_herron> on couples to all
[02:59:10] <archivist_herron> one
[02:59:28] <witnit> but each unit is modular to the machine except for cases which that unit is standalone or the "master unit"
[03:00:17] <witnit> so think of a machine with one panelbox and each unit is modular, but activated by the main panel
[03:00:56] <witnit> so I could basicly talk with and trigger each unit and then the unit would talk back to the main panel and then wait to reissue the command when the next part is in place
[03:01:31] <Jymmm> I dont care how it starts or is controlled, just that anyone near a station can shut the shit down without having to run across the room
[03:01:39] <witnit> always
[03:01:53] <witnit> if the machine has two operator sides then two buttons
[03:02:18] <anomynous> how do i know which package provides a file in debian?
[03:02:20] <anomynous> uninstalled
[03:02:28] <archivist_herron> google
[03:02:28] <anomynous> non-installed
[03:02:31] <anomynous> :D
[03:03:44] <Jymmm> https://www.google.com/search?ie=UTF-8&q=how%20do%20i%20know%20which%20package%20provides%20a%20file%20in%20debian%3F&gws_rd=ssl
[03:03:54] <anomynous> thanks Jymmm ! :D
[03:04:53] <witnit> Jymmm: you ever use rotary transfer machine?
[03:05:59] <Jymmm> witnit: I have a couple of these, they work great actually!
http://www.e-rackonline.com/product_images/2171.jpg
[03:06:45] <witnit> you funny man
[03:06:51] <witnit> :P
[03:06:57] <Jymmm> I'm dead serious,
[03:07:01] <witnit> wat
[03:08:16] <Jymmm> It's now got noflat tires and industrial casters, that thing is awesome!!!
[03:08:33] <witnit> hahaha yeah they look nice, but i was thinking of something more like this
http://www.graffpinkert.com/sites/default/files/styles/large/public/IMG_4951.JPG?itok=PfEMpkrh
[03:09:12] <Jymmm> How am I gonna move a frig, freezer, or stack of wood with that? ;)
[03:10:02] <Jymmm> that thing looks vicious though
[03:10:28] <Jymmm> each point having it's own motor and all
[03:11:08] <witnit> yeah those would also move out like a mill quill
[04:16:15] <pink_vampire> hi
[04:23:36] <pink_vampire> witnit: what is that monster?
[04:36:31] <XXCoder> hey pink_vampire
[04:37:04] <XXCoder> Jymmm: used to use those carts ay work constantly
[04:37:10] <XXCoder> and yes theyre awesome.
[04:37:18] <pink_vampire> hi XXCoder :)
[04:37:27] <XXCoder> whats up
[04:56:27] <witnit> pink_vampire: hydromat
[04:57:00] <witnit> "rotary transfer machine"
[05:01:12] <pink_vampire> witnit: what do you make with it?
[05:02:47] <witnit> https://www.youtube.com/watch?v=xslQ6Vlv_-k
[05:03:20] <witnit> thats a good example of some of its capabilities machining from 12' barstock
[05:04:59] <pink_vampire> witnit: so you are not making something spesific..
[05:06:35] <witnit> well, that was a whistle I guess
[05:06:47] <witnit> but generally fittings are made on such machines
[05:07:57] <XXCoder> interesting machine. like 6 lathes in one.
[05:07:58] <XXCoder> or 8
[05:07:59] <witnit> I run production machine which run similary parts but are much more like a lathe than that one
[05:08:50] <pink_vampire> witnit: you have it at home?
[05:09:00] <witnit> https://www.youtube.com/watch?v=XeAXMWLZW-0
[05:09:09] <witnit> this is more my style, but i run them at work
[05:09:14] <witnit> much too big for home
[05:09:51] <XXCoder> looks like something Lex luthor would make.
https://www.youtube.com/watch?v=GQjcaXZEj3c lol
[05:10:56] <witnit> https://www.youtube.com/watch?v=LVwbmSyAWOI
[05:11:03] <witnit> this is easier to see whats going on i think
[05:11:24] <witnit> those trunnions are serious business
[05:15:06] <witnit> Wickman makes another serious machine
[05:15:07] <witnit> https://www.youtube.com/watch?v=97JZX1JkYQk
[05:15:52] <witnit> they are better at making machines than picking background music for their videos tho
[05:16:56] <pink_vampire> I think linuxcnc is limited to 8 axis..
[05:17:55] <witnit> I didnt think there was a limit
[05:18:00] <witnit> I must know
[05:18:01] <witnit> hahaah
[05:18:26] <XXCoder> billion axis machine
[05:22:00] <witnit> https://forum.linuxcnc.org/forum/21-axis/2113-emc2-puma-9-axis
[05:23:12] <witnit> well we know atleast 9 now
[05:23:36] <witnit> Im betting it would do atleast 24 axis, maybe something like 32
[05:24:05] <witnit> I wonder what the max axis a mesa card combo can pull off
[05:24:05] <XXCoder> largest # of axis I ever found in youtube is 12
[05:24:10] <witnit> 32 i think
[05:24:28] <XXCoder> it was wire bender so large number of axis was tools move in/out.
[05:24:42] <witnit> wire benders are amazing
[05:24:46] <witnit> so fun to watch
[05:24:58] <witnit> spring making machines and whatnot
[05:25:01] <XXCoder> no cnc wire bender though
[05:25:06] <XXCoder> *home
[05:37:14] <witnit> any of you into grinding machinery?
[05:48:43] <XXCoder> I dont use any besides manual wheels for dulling sharp edges
[05:49:00] <XXCoder> well and recent new tool at work that grinds bits to have that groove for screw down
[05:51:43] <archivist_herron> I made a tool grinder for my cutters, but it is rather crap
[06:00:34] <ReadError> gday
[06:00:55] <XXCoder> cool
[06:00:56] <XXCoder> hey
[06:01:24] <ReadError> I might be missing something obvious here, but I am trying to change set_wait to 'done' so it replies after a command is finished
[06:01:31] <ReadError> http://hastebin.com/ilotimojib.xml
[06:01:49] <ReadError> but it seems there is no way to set
[06:09:36] <archivist_herron> messing with the handshake?
[06:10:56] <ReadError> archivist_herron well the app will just spew out gcode as quick as it can by default
[06:11:17] <ReadError> get set_wait
[06:11:17] <ReadError> SET_WAIT RECEIVED
[06:11:37] <ReadError> right now it responds right after it receives the command, rather than saying 'ok' im done
[06:12:26] <ReadError> set set_wait done
[06:12:27] <ReadError> set set_wait done
[06:12:27] <ReadError> SET SET_WAIT NAK
[06:12:41] <ReadError> http://linuxcnc.org/docs/2.7/html/man/man1/linuxcncrsh.1.html
[06:12:45] <ReadError> it says settable there
[06:17:38] <archivist_herron> I have an aversion to anything ignoring or attempting to work without handshakes
[06:17:55] <archivist_herron> you get overruns and data loss
[06:18:53] <ReadError> hm? its connecting etc fine
[06:19:16] <ReadError> its just the behavior of how it replies during operations is undesireable
[06:19:29] <archivist_herron> this shows up with large amounts of transfer, not the initial hello
[06:20:17] <archivist_herron> sender must not send if receiver has a full buffer
[06:20:38] <ReadError> well sure agreed
[06:20:42] <ReadError> but thats not what the problem is
[06:21:02] <ReadError> sender can wait, it just needs to know when linuxcnc has finished the operation
[06:21:20] <ReadError> and right now it just basically echos back whatever its sent instantly
[06:22:28] <archivist_herron> a lot of serial protocols had a command echo
[08:01:10] <anomynous> what raspberry pi has 185M or so memory?
[08:11:31] <_methods> don't all the rpi's have at least 512mb?
[08:11:38] <anomynous> apparently no
[08:11:40] <anomynous> :D
[08:11:46] <_methods> oh the first one had 256 maybe
[08:12:01] <anomynous> free says 181 i guess?
[08:12:08] <anomynous> total
[08:12:36] <archivist> which version and with os loaded?
[08:12:41] <_methods> yeah the first runs of the rpi A and A+ had 256
[08:12:50] <anomynous> dunno
[08:12:51] <_methods> after that they went to 512
[08:13:01] <anomynous> its the whatever debian thing made for rasp
[08:13:05] <archivist> but there is a new mini thing
[08:13:14] <_methods> pi zero
[08:13:19] <anomynous> maybe its that then
[08:13:21] <archivist> pi eff all
[08:13:23] <_methods> i think even it has 512
[08:13:26] <anomynous> :D
[08:14:07] <anomynous> watch your eyes

[08:14:19] <anomynous> how do you do that btw
[08:14:31] <_methods> yeah that must be an older pi A or A+
[08:14:47] <Jymmm> XXCoder: =)
[08:14:51] <archivist> probably uses some for the video
[08:15:45] <anomynous> i wondered where the memory is going. Videos steal it.
[08:15:51] <archivist> 65k stolen for video ram I bet
[08:16:20] <anomynous> how do they do that. Bad thing. Bad thing.
[08:16:37] <_methods> n the first 256 MB release model B (and model A), three different splits were possible. The default split was 192 MB (RAM for CPU), which should be sufficient for standalone 1080p video decoding,
[08:17:06] <_methods> 224 MB was for Linux only, with just a 1080p framebuffer, and was likely to fail for any video or 3D.
[08:17:19] <archivist> it is done in the hardware addressing

[08:17:42] <_methods> np
[08:18:10] <_methods> heh i have a rpi somewhere
[08:18:19] <_methods> no idea where it is anymore
[08:19:09] <archivist> I am pi free, so my arcs are broken :)
[08:19:51] <archivist> I am trying to diagnose a sampling or gearing error
http://www.archivist.info/cnc/wormtest/plot_vertex2_normalised.php
[08:20:20] <archivist> why only 45 peaks, should be 90
[08:23:55] <Jymmm> Google search results: "...you visited this page on 1/4/2016", in the near future they'll add"...you had roast beef sandwich with a pickle on the side and thought it was slightly too dill"
[08:25:14] <anomynous> well, did you?
[08:26:13] <Jymmm> anomynous: No, I hacored soemones phone cam sitting next to me
[08:26:19] <Jymmm> haxored*
[08:26:33] <anomynous> how did you do that?
[08:27:21] <Jymmm> anomynous: just create your own app and give it away for free =)
[08:28:26] <anomynous> mm. and ask all possible persmissions, right? And if thats not enough bypass selinux in android?
[08:28:36] <Jymmm> exactly
[08:28:42] <anomynous> how did you bypass it?
[08:28:54] <Jymmm> magic
[08:28:58] <anomynous> wow
[08:29:01] <anomynous> how does it work?
[08:29:09] <Jymmm> magical
[08:29:17] <anomynous> :/ but i didnt learn anything
[08:30:02] <Jymmm> Of course you did... you learned how to waste 2minutes of your life and you'll never ever get them back again =)
[08:30:13] <anomynous> i hope soon i gotta go pick up my car from repairs man
[08:30:14] <Jymmm> ...grasshopper

[10:09:11] <Erant> Is 4140 much harder to machine than 1018?
[10:22:01] <Erant> Hmm, a little bit. Probably not worth it for what I'm doing.
[12:03:35] <ReadError> PCW around?
[12:11:53] <pcw_home> is it good news or money?
[12:12:04] <ssi> or both!

[12:37:37] <Gemclip> Looking for a good current book on building a DIY CNC build. Any suggestions?
[12:42:00] <JT-Shop> I must look pretty rough... battery dead on the truck this morning so I take in to be checked and he said "it's almost gone you going to keep it or get a used battery?"
[12:42:39] <JT-Shop> Gemclip: the forum, mailing list and the IRC are your best source of the info... and sometimes the wiki.linuxcnc.org
[12:43:00] <Jymmm> JT-Shop: Eh, maybe he was just going you the benefit of the doubt
[12:43:06] <Jymmm> giving*
[12:43:32] <Jymmm> JT-Shop: No hard sell, etc.
[12:44:18] <Jymmm> JT-Shop: "Oh you need this 22K CCA battery with 60 second warranty"
[12:45:34] <JT-Shop> I thought it was kinda funny he offered me a used battery
[12:45:46] * JT-Shop is off to town in the truck
[12:45:59] <Jymmm> JT-Shop: ...with a new or used battery?
[12:47:01] <jdh> I usually buy the biggest that will fit
[12:47:43] <Jymmm> My last battery was from AAA, delivered and installed, at 4am
[13:22:34] <Simonious> zen toolworks mill a good choice for 2 sided PCB milling? I'm open to other options too.
[13:23:45] <_methods> yeah they're fine for pcb
[13:31:06] <FloppyDisk> @Gemclip: I haven't seen one... Sounds like a good idea...
[13:35:41] <Gemclip> Bummer all the ones I have are from 2003 and 2007
[13:36:11] <FloppyDisk> @Gemclip: Didn't know any existed... Do you have titles or isbn num?
[13:36:28] <Gemclip> yeah one sec
[13:36:30] <FloppyDisk> @simonious: othermill?
https://othermachine.co/othermill/tech-specs/
[13:37:06] <FloppyDisk> saw a guy who had one, think he used it a few times, not sure.
[13:37:47] <Gemclip> Build Your Own CNC Machine and CNC Robotics: Build Your Own WorkshopBot
[13:38:52] <Gemclip> ISBN-13: 9781430224891 and ISBN-13: 9780071418287
[13:39:01] <ReadError> Simonious, milling pcbs is so not worth it
[13:39:09] <ReadError> invest in a UV exposure setup
[13:41:01] <Simonious> ReadError: I'll look into that option too, thanks.
[13:41:42] <ReadError> its much more consistent in my experience
[13:41:44] <FloppyDisk> @Gemclip: thanks
[13:41:58] <Gemclip> youre welcome
[13:44:21] <Simonious> ReadError: and the drilling?
[13:44:38] <ReadError> Simonious, yea thats worth doing on a mill
[13:51:21] <FloppyDisk> @gemclip: ISBN-13: 978-1938687105 and ISBN-13: 978-0982110300 from amazon.
[13:51:45] <FloppyDisk> you just need to look at one or two and then look to the web. So many designs so you can decide what you want to do.
[13:52:18] <FloppyDisk> One of your books goes through the process of masking a PCB breakout board. You could buy one for $20 or less and be move on to the next piece.
[13:52:31] <FloppyDisk> All depends what level of integration you want to do... And, how good you want it.
[13:53:23] <FinboySlick> Othermill... Is this like "My other mill is a DMG" joke?
[13:53:34] <_methods> lol
[13:55:41] <FinboySlick> I guess you could at least mill that plaque with the othermill.
[14:51:57] <CaptHindsight> maskless printed circuit boards using a DLP projector for curing photoresists
[14:53:30] <CaptHindsight> an HD projector ac give you 4mil (100um) trace and space over a board ~4" x 8" (108mm x 192mm)
[14:53:39] <CaptHindsight> ac/can
[15:08:14] <malcom2073> I've heard of people doing that
[15:08:32] <malcom2073> A lot less finicky than the toner transfer method
[15:14:01] <CaptHindsight> it's also become popular for maskless lithography for low speed CMOS
[15:14:08] <CaptHindsight> and MEMS
[15:14:37] <CaptHindsight> with a reducing lens you can hit ~1um features
[15:30:17] <malcom2073> huh nice
[15:33:45] <pink_vampire> FloppyDisk: $2,199? !!?!
[15:34:07] <FloppyDisk> Ummm, it's put together I guess... I just saw it:-(
[15:34:27] <FloppyDisk> It would ship in a nice box:-)
[15:34:56] <pink_vampire> this is fucking junk!
[15:35:32] <FloppyDisk> Nice shipping box...
[15:35:38] <FloppyDisk> with a bow.
[15:35:47] <pink_vampire> in half of it you can get G0704 and be able to cut metal
[15:36:34] <pink_vampire> it will also come in nice box.
[15:36:46] <pink_vampire> http://www.grizzly.com/products/Drill-Mill-with-Stand/G0704
[15:37:28] <FloppyDisk> Yeah, that would work.
[15:38:58] <malcom2073> FloppyDisk: Wait a second, does that "othermachine" seriously call unsupported linear rod a "way"?
[15:40:25] <malcom2073> Eh, I guess that's not technically incorrect
[15:41:09] <archivist> a way to make crappy machines
[15:41:15] <ssi> :D
[15:41:15] <pink_vampire> FloppyDisk: I have it, the G0704 very nice machine
[15:41:21] <SpeedEvil> Depends on the rod diameter/load
[15:42:26] <pink_vampire> you can convert the G0704 with steppers, and it will cost you less then 2K$
[15:42:54] <SpeedEvil> My new kickstarter machine uses 12 linear ways to do all of the positioning. They are the highest quality italian you can buy. Some detractors have said that uncooked spaghetti is not a sutable material, but they do not understand!
[15:43:42] <archivist> and that can be grown on a spaghetti tree
[15:43:48] <malcom2073> SpeedEvil: it's 12x stronger than the competition! (where the competition is anyone running single noddle)
[15:43:53] <malcom2073> noodle even heh
[15:44:28] <pink_vampire> lol
[15:44:49] <archivist> 1957 april fools joke from the BBC
[15:44:57] <FloppyDisk> @pink_vampire - cool.
[15:45:09] <archivist> http://news.bbc.co.uk/onthisday/hi/dates/stories/april/1/newsid_2819000/2819261.stm
[15:45:45] <pink_vampire> FloppyDisk: why do you want a cnc machine?
[15:46:49] <FloppyDisk> I have one, someone asked about milling pcb boards and I had heard of the othermill. I have a supermax conversion to 5i25/7i77.
[15:47:34] <FloppyDisk> I 3d printed some fixtures for an encoder board to mount on the spnidle, need to get out and mount it:-)
[15:47:47] <FloppyDisk> Hoping to try the rigid tapping, no time, other projects to finish first.
[15:48:20] <pink_vampire> what model?
[15:58:57] <FloppyDisk> @pink_vampire, I don't see the p/n on the machine, but googled a supermax ycm-16vs and that's it.
[15:59:54] <FloppyDisk> I was going to get a smaller benchtop mill and then figured, what the heck, wasn't that much more, but took a long time to get it going.
[16:00:27] <FloppyDisk> Pix here if you're interested, this is pre-retro:

[16:10:25] <FinboySlick> Jymmm: You around?
[16:12:48] <Jymmm> FinboySlick: No, leave a message at the beeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeep
[16:13:20] <FinboySlick> Jymmm: This is a shot in the dark, but do you per chance follow AvE on Youtube?
[16:13:39] <Jymmm> FinboySlick: No, what/who is it?
[16:14:19] <FinboySlick> Does tool reviews and very-bad-machining (tm).
[16:14:28] <FinboySlick> Very very entertaining.
[16:14:31] <Jymmm> hahaha
[16:14:45] <Jymmm> I suppose entertainent is subjective =)
[16:15:18] <Jymmm> FinboySlick: I usually cringe at things that are down right stupid though.
[16:16:29] <FinboySlick> Nah, he's pretty smart. His bad machining is done without pretention of being a machinist. Though he did torture a bunch of drill bits just to annoy the people who keep bugging him about speeds and feeds ;)
[16:16:57] <Jymmm> FinboySlick: Ah, a smartass. Okey well that's different then.
[16:17:42] <FinboySlick> He also cobbled together a 100ton press called 'little screwy' in about 4 hours.
[16:18:02] <FinboySlick> Uses it to punch 1" holes in 8mm steel.
[16:18:34] <Jymmm> 25ton per hour, wth?! Tell hime to get off his lazy ass ;)
[16:18:43] <malcom2073> Heh, he's amusing
[16:19:30] <FinboySlick> Jymmm: This is his review of a second-hand Hilti rotary hammer:

[17:07:06] * JT-Shop shuts down this computer to install a network card so he can start figuring out the 7i92
[17:37:22] <JT-Shop> well that didn't work it only takes PCI-E cards :(
[18:06:46] <Jymmm> JT-Shop: I have a zircom ethernet if you want it
[18:10:38] <FloppyDisk> JT-Shop: I guess you're moving to a different strategy away from the 5i25 and 7i77sol. Was hoping you'd have better success, sigh:-(
[18:22:15] <JT-Shop> Jymmm: I'll just use a different computer but thanks for the offer
[18:23:59] <JT-Shop> well I'm open to anything that works with my mill, right now even with the 7i77ISOL I get a string of sserial errors no matter what I try so time to figure out the 7i90
[18:24:34] <JT-Shop> err 7i92
[18:27:38] <JT-Shop> FloppyDisk: I've used the 5i25 7i77 for quite some time on the BP in fact I think I have one of the first ones... this is just a burp in the software I assume
[18:30:02] <FloppyDisk> JT-Shop: I know - I've copied your vfd and other setup items (thank you). I did buy a rasmi filter... It's freakin' huge (40amps), not sure where I'll mount it...
[18:31:21] <JT-Shop> that's why I got the AD filter that was designed for the GS2
[18:31:59] <FloppyDisk> That ad filter was a good idea.
[18:39:13] <JT-Shop> quickbooks sucks
[18:41:58] <Jymmm> JT-Shop: np
[18:50:43] <PCW> JT-Shop are you sure the cable between the 5I25 and 7I77 is a IEEE-1284 cable?
[18:51:22] <JT-Shop> yes, I got it from you
[18:53:06] <FloppyDisk> Mine, too... I had used an L-com cable that I think is IEEE-1284, but then swapped it out for mesa included cable to make sure.
[18:53:16] <PCW> if you get errors even with isolation it means that its not a ground loop back to the PC but rather volts of noise coupled into the cable some how
[18:53:18] <PCW> (assuming the cable shell is _only grounded_ and the PC end)
[18:53:30] <PCW> at the PC end
[18:54:51] <PCW> does the DB 25 cable run near any power lines? (or grounds between devices)
[18:56:25] <JT-Shop> yes, it runs parallel to a couple of ground wires
[18:56:56] <PCW> you might try running it away from everything as a test
[18:57:45] <JT-Shop> ok
[18:58:35] <PCW> shielding reduces elecrostatic coupling but does little against magnetic coupling (and use the filtered firmware that should help a bit)
[19:00:27] <PCW> (I was able to use a crappy 5 foot flat cable with a 5I25/7i77 with the filtered config which immediately errored out with a the normal config)
[19:02:43] <FloppyDisk> What's weird about all this, is I was able to run my 5i25/7i77 with one program and it errored at the end of it.
[19:03:01] <FloppyDisk> Otherwise, it always errored right away. This is w/ out the improved firmware.
[19:03:08] <FloppyDisk> Anyway, I need to look at it more.
[19:05:13] * JT-Shop hears the dinner bell...
[19:11:18] <FloppyDisk> Go get the vittles!
[22:41:42] <A_Nub> Hey guys, I have been doing 2D profiles for some time and today wanted to try a 3D profile, however it seems my z axis is inverted, or I am just being retarded
[22:41:51] <A_Nub> for 2D milling I usually set home for max Z height
[22:42:05] <A_Nub> and then touch the top of the workpiece for touch off, then go
[22:42:24] <A_Nub> and milling depth is usually negative in cambam
[22:42:40] <A_Nub> however when i tried this with a 3D profile it just climbed in the air
[22:42:48] <A_Nub> and did it's movements near the touchoff
[22:43:10] <A_Nub> Is this an inverted z-axis? bad gcode? or me just misunderstanding homing/touching off
[22:43:39] <archivist> not inverted, the direction is correct
[22:44:34] <A_Nub> it seems like the cut is inverted however, it climbs slow, crosses slow, then dives fast
[22:44:36] <archivist> how did you create the gcode, that does not appear to realise 0 is at the top surface
[22:44:48] <A_Nub> with cambam 3D profile
[22:44:53] <A_Nub> I selected top,left
[22:45:01] <A_Nub> for start point
[22:45:24] <A_Nub> Other than that it's mostly stock settings other than setting my stock height and toolsize
[22:47:13] <A_Nub> archivist: it's treating zero as the bottom, and at the same time moving the tool through the part for moves
[22:47:20] <A_Nub> which is why I feel it's inverted
[22:47:51] <A_Nub> but my 2D cuts seem to work fine, I just always felt homing in the air was weird
[22:48:01] <A_Nub> I thought homing on the bed made more sense so we don't cut it
[22:48:23] <archivist> home is at the top on Z
[22:48:53] <archivist> 0 and cut - is normal, I have no idea how to use cambam
[22:49:16] <A_Nub> Yea, I'm just making sure I was doing things correctly on the operation side
[22:49:37] <A_Nub> So home = top, touch = workpiece surface
[22:49:38] <A_Nub> right?
[22:49:46] <A_Nub> then the gcode should know the depth etc
[22:49:54] <A_Nub> thats how I've been doing 2D cuts
[22:49:58] <A_Nub> works fine
[22:50:29] <archivist> does cambam assume something different, doeas it have any settings you missed
[22:50:32] <A_Nub> I'll play around with it more.
[22:50:39] <A_Nub> yea it has a ton of settings
[22:51:06] <A_Nub> is there a term I should be looking for?
[22:51:25] <A_Nub> bottom,left was the default origin, so I selected top,left after my first failure
[22:51:35] <A_Nub> nothing different seemed to have happened
[22:55:41] <A_Nub> Ahh it was my clearance plane for moves
[22:55:46] <A_Nub> It was at 0...
[23:23:04] <mattygalore> I always set Z=0 at the top of the workpiece, and do all milling in -Z
[23:24:27] <mattygalore> and I have a safety height of + a few mm for clearance on rapid moves
[23:26:23] <mattygalore> I don't have home switch at the bed, but even if I did, I think I'd still touch off on the workpiece each time, with G92, to set Z=0 there
[23:28:59] <anomynous> someone say my name :D
[23:29:32] <mattygalore> anomynous
[23:29:45] <anomynous> bleh
[23:29:52] <mattygalore> is your client loud enough?
[23:29:56] <anomynous> no
[23:30:23] <anomynous> i want irssi to use bell when a hilight happens
[23:30:36] <anomynous> can i do that, so term could hilight on desktop
[23:32:52] * mattygalore sells app with crowd of schoolgirls. one starts screaming your name every time you're mentioned on social media. aim is get them all screaming constantly
[23:33:56] <anomynous> no thank you :D
[23:34:02] <anomynous> im not on facebook etc :)
[23:36:12] <mattygalore> so the girls all sneer and call you granddad, until you do
[23:37:22] <mattygalore> then I take kickbacks from facebook or else the girls will prefer myspace
[23:39:12] <anomynous> i dont really care
[23:39:15] <anomynous> :D
[23:39:22] <anomynous> not everyone calls me a grandad
[23:39:28] <anomynous> and those who want to, may do so
[23:40:31] <mattygalore> and I'll take kickbacks from apple to make them sneer if your phone is a dad phone :D
[23:40:52] <anomynous> its brand new microsoft phone, though i didnt buy it
[23:40:53] <anomynous> :D
[23:41:12] <anomynous> but why would someone be interested what phone i have?
[23:42:43] <mattygalore> it's a status thing with some people
[23:43:24] <mattygalore> I see nothing wrong with exploiting such people for profit. I wish I'd done that iamrich app
[23:44:11] <anomynous> njaa.
[23:44:24] <mattygalore> $1000, does nothing except display a shiny jewel, sold 8 copies before Apple panicked and pulled it
[23:44:26] <anomynous> thats "oh." in finnish.
[23:45:24] <mattygalore> one of the purchasers was tracked down and he said he was delighted with his purchase, and he expected it to gain value. with only 8 he's probably right
[23:45:43] <anomynous> really.
[23:47:03] <anomynous> im kinda like that. I bought 70€ earphones for gaming when 40€ would do fine.
[23:47:33] <anomynous> and theyre a brand thing too. My friend said I should get money from akg for walking around with them since it has a big logo
[23:47:49] <anomynous> i thought about camouflage liquid rubber with some texture :D
[23:49:30] <mattygalore> walking around gaming?
[23:49:45] <anomynous> yes, yes. Or listening music. But I use them for gaming.
[23:49:47] <anomynous> so youre right
[23:49:49] <anomynous> :D
[23:51:31] <anomynous> but theyre nice for listening music too. Comfy and good sound. If it were better, it would be excessive :D
[23:53:57] <mattygalore> I've got some nice earbuds. I prefer them now apart from the wax
[23:54:55] <mattygalore> I've got a set here with 6 channels for gaming in surround sound, but I've never gone to the trouble of using them. the 3 plugs aren't labeled for a start
[23:55:23] <anomynous> i would have liked over ears things but they would have been too expensive in my opinion
[23:58:11] <mattygalore> the perfect headphones would let you lsten to music, protect your ears from workplace noise, and yet still let through voices of coworkers
[23:58:34] <anomynous> peltor radio protectors :D
