[04:51:01] <likevinyl> morning 4 all \m/
[05:37:49] <Deejay> moin
[05:52:51] <jthornton> morning
[07:04:25] <Tom_itx> 47F morning
[07:06:49] <likevinyl> 58 ° F :)
[07:07:42] <likevinyl> igtw
[07:08:17] <SpeedEvil> 59 here.
[07:11:42] <archivist> the right weather to be outside making a clock movement test horse
[07:12:42] <archivist> mine is seriously stronger and more rigid than this crap lower left http://www.clocktonyforclocks.com/
[07:14:50] <Tom_itx> but it says it's well made...
[07:14:58] <archivist> lies
[07:15:12] <archivist> he has no shear struts
[07:15:25] <Tom_itx> i was getting ready to add that comment
[07:16:00] <SpeedEvil> I suspect shear struts are irrelevant unless you bolt it down
[07:16:52] <archivist> the frame starts to swing if you dont have it bolted to a wall or shear struts
[10:08:19] <CaptHindsight> http://www.youtube.com/watch?v=XX8JG1tqEM4#t=97 hhmm would a structural engineer really build a machine this poorly?
[10:10:26] <CaptHindsight> http://3dprintingindustry.com/2014/05/14/3d-printing-home-rudenko/ ah explains it "a contractor with a background in architecture and engineering"
[10:15:06] <mazafaka1> 'structural engineer...' isn't this just a part of the education?
[10:15:56] <mazafaka1> To be honest, the hardest in my life was to confront with legislative norms during car rebuild.
[10:18:30] <mazafaka1> Had to as wether I have a right to mount some tools for off-roading under the bonnet, answer was 'yes'--but I will need to register this changes in a specified order, involving some on-line writing with photos to the special organisation.
[10:20:21] <CaptHindsight> mazafaka1: what country was this in?
[12:02:42] <gene78> ok, I'll bite, where have the trig functions (sin-cos-tan etc) gone in 2.5.4?
[12:11:38] <archivist> http://linuxcnc.org/docs/2.5/html/gcode/overview.html#sec:Expressions
[12:11:51] <IchGuckLive> hi all B)
[12:13:06] <archivist> IchGuckLive, can you remember the url for that gear company over there?
[12:13:22] <archivist> cheap worms and bevels
[12:13:37] <IchGuckLive> http://www.maedler.de/
[12:13:48] <archivist> thanks
[12:13:58] <archivist> must bookmark this time
[12:14:02] <IchGuckLive> in all plasmas now i got a 30:1
[12:14:43] <IchGuckLive> that retches the 7500 on mesa 7i76 kit and it gives a 8h+ workday with no steploss
[12:15:05] <IchGuckLive> mm/min
[12:35:45] <IchGuckLive> balestrino: Bonjorno tuttie
[12:36:35] <IchGuckLive> balestrino: che rende la fresatura
[12:37:11] <IchGuckLive> balestrino: legno, per quanto ne so
[12:37:31] <balestrino> ?
[12:37:48] <IchGuckLive> Italiano ?
[12:37:51] <balestrino> yes
[12:38:13] <IchGuckLive> ;-)
[12:39:42] <balestrino> currently i'm working on aluminum plates and dont know.. but i got a bug i think
[12:40:12] <balestrino> on tool table because get trunkated over 200+ tools
[12:40:18] <IchGuckLive> bug on aluminium plates how coudt that happen
[12:40:53] <IchGuckLive> 200 tools nowone needs that many 36
[12:41:35] <balestrino> yeah. i dont have all that tools but i set the table like 0-100 endmills, 100-200 drills, etc
[12:42:06] <IchGuckLive> what version are you on
[12:42:16] <balestrino> latest one with gmoccapy
[12:42:31] <IchGuckLive> OS
[12:42:40] <balestrino> ubuntu 10.x
[12:43:55] <IchGuckLive> you shoudt consider 2.6 pre
[12:45:48] <archivist> there is a tool qty table limit on the current versions (documented somewhere)
[12:46:20] <balestrino> i'm going to check. But why limit the tool table?
[12:46:40] <IchGuckLive> the limit on standart is 56
[12:46:52] <IchGuckLive> but pre is removerd to 254
[12:47:15] <archivist> the transport mechanism has a size limit
[12:47:27] <archivist> buffer size
[12:48:55] <IchGuckLive> archivist dident mhableer put that to the string page limitation of 256 up
[12:49:44] <IchGuckLive> the remap funktion did need the bigger buffer on transport tm6
[12:49:50] <archivist> I know it is being worked on
[12:50:13] <IchGuckLive> as remap is only on 2.6 it might work out there
[12:52:34] <Connor> WooT, got me ER20 Collets in today.
[12:52:51] <IchGuckLive> nice for you
[12:52:53] <balestrino> Norbert of gmoccapy has ever been on IRC?
[12:53:38] <IchGuckLive> Connor: http://www.paulimot.de/epages/paulimot.sf/de_DE/?ObjectPath=/Shops/paulimot/Categories/%22Spannzangen%20%28ER%29%22/ER20
[12:53:38] <Connor> Not that I know of. Wish he would show up.. I have a few questions...
[12:54:09] <Connor> IchGuckLive: $5.00 USD each for mine.
[12:54:24] <IchGuckLive> even better
[12:55:09] <Connor> AND. Interestingly enough, they're labeled Spannzange / collet
[12:55:32] <IchGuckLive> in set 5,8 here if you take 12
[12:55:36] <Connor> and come in clear tubes with yellow endcaps.. I don't think these are Chinese.
[12:55:50] <IchGuckLive> sweden
[12:57:17] <Connor> and they have a mark on the labels O < .008 then < has a line under it..
[12:57:32] <Connor> I think that's the tolerance for the collet size ?
[12:57:41] <Connor> not the run-out..
[12:59:04] <archivist> you can work it out from how many you get in a set what the range is
[13:01:32] <Connor> http://www.dzsalesllc.com/er20-collets-14piece-set-p/20-cs14.htm
[13:01:48] <Connor> Okay. the .008 was mm
[13:01:55] <Connor> Runout:.008mm/.0003149in TIR
[13:07:56] <IchGuckLive> Connor: this is the standard on high precision coolets DIN6499
[13:08:28] <Connor> So, Those are good then ?
[13:08:35] <IchGuckLive> i looked at the quality listings in the hardings pdf
[13:08:54] <IchGuckLive> http://www.hardingeus.com/usr/pdf/collet/2351F_tool_holders.pdf
[13:08:58] <IchGuckLive> page 13
[13:10:35] <Connor> OKay.. What am I looking for ?
[13:11:04] <IchGuckLive> TRi
[13:27:35] <archivist> before you had linux cnc you needed humans for the automation http://www.collection.archivist.info/searchv13.php?searchstr=Women+machine
[13:28:46] <CaptHindsight> if you search for gearboxes, worm gears, gear reduction on ebay with "North America" for location just about everything small <1HP disappears
[13:30:17] <archivist> but.., http://www.sdp-si.com/ is over there
[13:30:39] <zeeshan-laptop> <-- needs a powerful light source
[13:30:50] <zeeshan-laptop> that overpowers your standard 100w flourescent lights
[13:31:01] <zeeshan-laptop> for a machine vision system
[13:31:10] <zeeshan-laptop> any recommendations? :D
[13:31:19] <CaptHindsight> where do they hide the prices on that German worm gear site?
[13:31:28] <archivist> dunno
[13:31:55] <CaptHindsight> zeeshan: what are you really looking for? why overpower?
[13:32:12] <pcw_home> what area?
[13:32:20] <CaptHindsight> are you getting flicker?
[13:32:20] <archivist> to get a crappy lens to shut down to be usable
[13:37:45] <zeeshan-laptop> CaptHindsight: no
[13:37:54] <zeeshan-laptop> the reflection on the sample throws off the aramis cameras
[13:38:08] <zeeshan-laptop> so i need a light that overpowers the ambient light
[13:38:13] <zeeshan-laptop> so there is a uniform light distribution on it
[13:38:44] <pcw_home> LED ring light?
[13:39:02] <CaptHindsight> yeah lots of led lights/lamps
[13:39:45] <CaptHindsight> and add a diffuser
[13:39:45] <zeeshan-laptop> hmm
[13:39:55] <zeeshan-laptop> add diffuser in front of light ymean
[13:39:58] <zeeshan-laptop> you mean
[13:40:03] <zeeshan-laptop> gotcha
[13:41:04] <pcw_home> http://www.dx.com/p/ng-ng-40c-ring-shaped-40w-3166lm-5400k-white-macro-photography-light-black-214589#.U3O0hKGYNoA
[13:41:52] <zeeshan-laptop> fancy
[13:41:53] <zeeshan-laptop> :D
[13:42:08] <CaptHindsight> are you illuminating a large area?
[13:42:21] <zeeshan-laptop> yes
[13:42:26] <zeeshan-laptop> 6"
[13:42:34] <zeeshan-laptop> diameter
[13:43:07] <CaptHindsight> lots of soft lamps available for photography
[13:44:16] <CaptHindsight> http://www.skaeser.com/servlet/the-782/Photography-Studio-Lighting-425/Detail?gclid=CKeQlIeFrL4CFeY-Mgodqx4Arg or similar
[13:45:52] <CaptHindsight> http://www.skaeser.com/servlet/the-250/Photo-Studio-Tent-30in%2C/Detail these might be an option as well
[13:46:10] <CaptHindsight> not sure what your targets are
[13:47:51] <archivist> I just bought a bunch of white LEDs and made my own ring light
[13:50:20] <zeeshan-laptop> im just gonna play around with some led lights
[13:51:34] <CaptHindsight> can you measure your distortions using the shadows?
[14:11:12] <DaViruz> i'm looking to get a bunch of those rings you mount on 1/8" tooling to set the length, but i can't seem to find any
[14:11:28] <DaViruz> i'm pretty sure i found lots when i wasn't looking
[14:12:40] <archivist> comes on PCB tooling
[14:13:28] <cradek> yeah they come already mounted (I think they're commonly called "depth rings")
[14:14:13] <DaViruz> oh
[14:15:49] <DaViruz> http://www.crownhill.co.uk/level3.php?cat=51
[14:16:10] <archivist> http://www.ebay.co.uk/itm/10Pcs-PCB-Print-Circuit-Board-Carbide-Micro-Drill-Bits-Tool-0-3mm-to-1-2-mm-New-/121320570508?pt=UK_Home_Garden_PowerTools_SM&hash=item1c3f44fe8c
[14:16:13] <DaViruz> these guys seem to have some, but how are they supposed to be mounted? i was imagining a set screw or clamp type arrangement
[14:16:22] <archivist> press fit
[14:17:20] <DaViruz> i see
[14:18:12] <DaViruz> preferably i would like some miniature quick change tooling system, but that seems scarce
[14:18:51] <zeeshan-laptop> are smd led much brighter than the tradiational leds?
[14:19:05] <zeeshan-laptop> i see ring lights that make use of either or
[14:19:30] <CaptHindsight> everything is moving to smt vs thru hole
[14:19:45] <zeeshan-laptop> ive just noticed first hand
[14:19:50] <zeeshan-laptop> that smt leds seem to be brighter?
[14:19:58] <zeeshan-laptop> i dont know if its my esey
[14:19:58] <DaViruz> through hole leds are kind of hard to dissipate heat from
[14:20:04] <zeeshan-laptop> or if its the type of led
[14:20:04] <CaptHindsight> it's just the package, so often the same led die are available in either
[14:20:16] <zeeshan-laptop> ah
[14:20:33] <CaptHindsight> but more are available in SMT
[14:20:53] <zeeshan-laptop> ive been tryig to find 100w ring lights
[14:20:58] <zeeshan-laptop> its not too common
[14:21:00] <zeeshan-laptop> it looks like
[14:22:35] <zeeshan-laptop> CaptHindsight: do they make smt type of leds
[14:22:37] <zeeshan-laptop> not in ring format
[14:22:40] <zeeshan-laptop> but in a square format?
[14:22:43] <zeeshan-laptop> so you can pack more leds
[14:23:10] <CaptHindsight> the packages are square but they just solder them to a ring shaped circuit board
[14:23:20] <archivist> you can get ready mounted arrays
[14:23:30] <zeeshan-laptop> archivist: is that the keyword i should search?
[14:23:34] <zeeshan-laptop> 'led array'?
[14:24:06] <archivist> some led lamps are cheap enough to raid for the pcb
[14:24:22] <CaptHindsight> http://www.ebay.com/itm/Adjustable-Photography-300-LED-Ring-Light-DSLR-Camera-Video-Camcorder-Lighting-/231230377476?pt=LH_DefaultDomain_0&hash=item35d6678e04
[14:24:45] <CaptHindsight> http://www.ebay.com/itm/48-LED-RECHARGEABLE-VIDEO-CAMERA-MACRO-RING-LIGHT-for-Canon-Nikon-Sony-Studio-/181213349806?pt=LH_DefaultDomain_0&hash=item2a312847ae
[14:24:55] <zeeshan-laptop> CaptHindsight: not like that
[14:24:59] <zeeshan-laptop> lemme see if i can find a pic
[14:25:15] <zeeshan-laptop> http://www.gom.com/typo3temp/pics/c30a10a68c.jpg
[14:25:22] <zeeshan-laptop> cameras are at an angle
[14:25:26] <zeeshan-laptop> middle is the light
[14:27:33] <CaptHindsight> http://www.ebay.com/itm/100W-LED-Cool-white-Power-8000-9000LM-LED-Lamp-SMD-Chips-for-DIY-lights-bulbs-/251530267876?pt=US_Lighting_Parts_and_Accessories&hash=item3a905f4ce4
[14:28:10] <zeeshan-laptop> CaptHindsight: very nice
[14:28:12] <zeeshan-laptop> !!!
[14:28:33] <CaptHindsight> that array is probably 100x 1w leds
[14:28:55] <CaptHindsight> each led is ~1m x 1m
[14:29:14] <zeeshan-laptop> roughly 2"x2" square
[14:29:26] <zeeshan-laptop> thats perfectly
[14:29:42] <zeeshan-laptop> then i can just put a piece of plexi in front of it
[14:29:47] <zeeshan-laptop> that is frosted
[14:29:51] <CaptHindsight> I have a bunch here in UV to Blue
[14:30:01] <CaptHindsight> yeah, to diffuse the light
[14:30:34] <zeeshan-laptop> CaptHindsight: is it blindlingly bright? :D
[14:30:37] <CaptHindsight> you'll also need a constant current power supply and a P4 size heatsink
[14:31:10] <zeeshan-laptop> 3.5A constant power?
[14:31:21] <zeeshan-laptop> see thats a bit confusing to me
[14:31:22] <CaptHindsight> I'd look for a complete lamp vs build it yourself
[14:31:29] <zeeshan-laptop> CaptHindsight: help me find it!
[14:34:14] <CaptHindsight> http://www.ebay.com/itm/High-Power-10-30-100W-LED-Flood-light-Warm-White-Outdoor-Spotlight-Lamp-IP65-/350945945693?pt=US_Night_Lights&var=&hash=item51b602285d
[14:35:38] <zeeshan-laptop> dude
[14:35:43] <zeeshan-laptop> thats perfect
[14:35:56] <zeeshan-laptop> 90$
[14:35:57] <zeeshan-laptop> not bad
[14:36:00] <CaptHindsight> i"m not 100% that they come with everything
[14:36:11] <CaptHindsight> have to read the fine print
[14:36:49] <CaptHindsight> http://www.ebay.com/itm/100W-Warm-White-IP65-Floodlight-High-Power-LED-Flood-Wash-Light-Outdoor-Lamp-SMD-/200933895299
[14:37:17] <zeeshan-laptop> looks like its just the heat sink
[14:37:22] <zeeshan-laptop> and enclosure
[14:37:31] <CaptHindsight> you can buy diffuser for spot light for a few $ a sq ft
[14:37:58] <zeeshan-laptop> the only problem with it
[14:37:59] <zeeshan-laptop> is its huge
[14:38:11] <CaptHindsight> that last link looks like a complete just ad AC power
[14:38:22] <zeeshan-laptop> 16" x 11"
[14:38:42] <CaptHindsight> well 100 W convection only heat sink
[14:39:05] <zeeshan-laptop> i rather have 6x6" max footprint
[14:39:07] <zeeshan-laptop> with fan
[14:39:09] <CaptHindsight> the LED die has to be <100C to have any life
[14:39:10] <zeeshan-laptop> but ill keep looking
[14:39:22] <CaptHindsight> yeah, dig around now that you what they are
[14:39:44] <zeeshan-laptop> thank you for your help!
[14:40:21] <CaptHindsight> the LED's are only ~30-50% efficient so 1-2x that power is heat
[14:41:30] <CaptHindsight> 100W or light but 100-200W of heat that you have to dissipate from an area only 1^2 in
[14:44:36] <CaptHindsight> zeeshan: 100w led is pretty bright, maybe you only need 16-30w led
[14:44:37] <Jymmm> Tom_itx ping
[14:44:42] <Tom_itx> do those come with the sealed housing?
[14:44:46] <Tom_itx> pong
[14:44:55] <CaptHindsight> http://www.ebay.com/itm/Non-Dimmable-PAR38-16-Watt-LED-Spot-or-Wide-Angle-Light-Bulb-100W-Replacement-/230963330796
[14:45:12] <zeeshan-laptop> CaptHindsight: check this out
[14:45:16] <Jymmm> Tom_itx: The apex case you have, can a SDD be mounted directly to where the FDD would go or o do oyu need an adapter?
[14:45:23] <Jymmm> err SSD
[14:47:21] <Tom_itx> Jymmm, http://tom-itx.no-ip.biz:81/~webpage/intel_atom/detail/DSC_0004.JPG
[14:47:25] <Tom_itx> (big)
[14:47:44] <Tom_itx> ssd on the bottom
[14:47:50] <Jymmm> Tom_itx: did you use an adapter to mount it?
[14:47:50] <Tom_itx> i mounted a hdd on the side
[14:47:57] <Tom_itx> it came with one
[14:48:21] <CaptHindsight> zeeshan: maybe http://www.ebay.com/itm/14w-18w-24w-E27-SMD-LED-bulb-light-lamp-Energy-Saving-Ceiling-Spot-Downlight-/321293732809
[14:48:22] <Tom_itx> http://tom-itx.no-ip.biz:81/~webpage/intel_atom/SSD1.jpg
[14:48:47] <Jymmm> Tom_itx: OH, the SSD came with an adapter, I thought the case did
[14:48:50] <Jymmm> OH*
[14:49:08] <Tom_itx> yep
[14:49:23] <Jymmm> thanks
[14:49:31] <Tom_itx> i think the case came with 2 plastic rails but i can't remember
[14:49:40] <Jymmm> rails for???
[14:51:05] <Tom_itx> http://tom-itx.no-ip.biz:81/~webpage/intel_atom/atom2.jpg
[14:51:12] <Tom_itx> to mount a hdd
[14:51:17] <Tom_itx> but i put it sideways there
[14:51:43] <Tom_itx> hard to see the rails there
[14:53:11] <Jymmm> it'sall good.. thank you =)
[14:55:19] <Jymmm> Tom_itx: is there a fan anywhere?
[14:55:30] <Jymmm> Tom_itx: in the PS ?
[14:55:31] <Tom_itx> nope, just in the psu
[14:55:36] <Jymmm> gotcha
[14:55:53] <Jymmm> the PS does have a fan?
[14:56:11] <Jymmm> doens't show here http://www.newegg.com/Product/Product.aspx?Item=N82E16811154091
[14:56:54] <Tom_itx> bottom mounted
[14:57:04] <Jymmm> got it =)
[14:57:37] <Tom_itx> someone linked the replacement PS for them here quite a while back
[14:58:09] <CaptHindsight> http://www.newegg.com/Product/Product.aspx?Item=N82E16811119286 just FYI, these have lots of room and work well, I can also fit a 2nd power supply and 3-axis stepper driver for all in one.
[14:58:19] <Jymmm> nice
[14:58:56] <Tom_itx> probably the same footprint as mine but taller
[15:00:14] <Tom_itx> does it come with a PS?
[15:00:40] <Jymmm> CaptHindsight: But it's cool master
[15:01:25] <Jymmm> CaptHindsight: does the front open like a door?
[15:01:34] <Jymmm> CaptHindsight: can you mount a 120m fan in there?
[15:01:52] <Jymmm> CaptHindsight: does that use a atx PS?
[15:01:58] <Tom_itx> probably push tabs on the front like mine
[15:02:17] <Jymmm> oh, says 120mm radiator in the front
[15:02:20] <CaptHindsight> Jymmm: it has a 120mm fan included in the front
[15:02:46] <CaptHindsight> uses, but does incluse an atx supply
[15:02:54] <Jymmm> CaptHindsight: thanks
[15:03:04] <CaptHindsight> http://www.newegg.com/Product/Product.aspx?gclid=CLOQhreWrL4CFaNhMgod7BAAhA&Item=N82E16811208055&nm_mc=KNC-GoogleAdwords&cm_mmc=KNC-GoogleAdwords-_-pla-_-Computer+Cases-_-N82E16811208055&ef_id=U3PHhAAABYLIUwlo:20140514194404:s
[15:03:09] <Tom_itx> PS included on mine
[15:03:19] <CaptHindsight> ^^ comes with power supply and only $40
[15:04:22] <Jymmm> I am just not fond of cool master at all
[15:04:42] <Jymmm> just a bad reputtion to their products
[15:05:04] <CaptHindsight> haven't had any problems so far
[15:05:32] <CaptHindsight> but these were all cheap <$100 cases
[15:06:16] <Jymmm> CaptHindsight: how can it fit 3x HDD ?
[15:08:01] <CaptHindsight> use two larger 1.5x drives?
[15:08:17] <Jymmm> LOL, no it says that it can, I just can't see how.
[15:11:10] <Jymmm> Tom_itx: Is this a 3.5 or 2.5 hdd?
[15:27:53] <CaptHindsight> http://www.digitalmachinist.net/workshop no workshop this year
[15:28:28] <CaptHindsight> looks like no Linuxcnc-fest this year either unless somebody has suggestions
[15:31:41] <cpresser> lets do a linux-cnc-fest in europe :)
[15:33:39] <CaptHindsight> pick a spot
[15:33:51] <CaptHindsight> wasn't there a small one there last year?
[15:35:00] <cpresser> we could meet up in hamburg during 31C3
[15:35:19] <cpresser> the space is free, and there are a lot of hacker/nerds around
[15:35:40] <CaptHindsight> yeah but thats for nerds :)
[15:36:03] <cpresser> this is also for nerds, its called IRC^^
[15:38:36] <Deejay__> re
[16:10:46] <Connor> Building a tool rack for my TTS tools.. what sort of spacing do you think I need ?
[16:11:46] <Einar1> Varying. Equal spacing enough to hold the biggest tools is a waste of space.
[16:12:29] <Connor> Well, I'm using TTS holders (ER20's and Set Screw)
[16:12:43] <Connor> I don't think I'll have anything super large.. maybe a drill chuck.
[16:12:56] <Einar1> Or a slitting saw?
[16:13:21] <Connor> I don't think I would leave the blade on a slitting saw..
[16:13:27] <Connor> Probably just keep the arbor..
[16:14:06] <Connor> but, then again, who the hell knows... :)
[16:14:45] <Connor> Adding a shelf to go under the PC. I'll have 17.5" x 26" area to work with.. Would like to keep my most used tooling on it..
[16:15:09] <Connor> not sure if I want to make the shelf solid and make some sort of rack that goes on it.. or just bore holes in the shelf itself.
[16:46:41] <Deejay> gn8
[17:46:10] <andypugh> Connor: Do you have a big face mill?
[17:46:25] <andypugh> You can always just ignore the space next to it if you do anyway.
[17:48:04] <andypugh> You probably want a home for the spare ER20 collets too.

[18:00:31] <JT-Shop> well that won't work comp changes _ to - in pin names
[18:03:15] * JT-Shop can't think of a way to test a Mesa config without the cards plugged in :(
[18:03:42] <PCW> buy more cards
[18:04:51] <PCW> what component is missing?
[18:06:47] <JT-Shop> I'm trying to make a simulated component with some of the pins of the 5i25 and 7i76
[18:07:03] <JT-Shop> just so I can work on a different part of the configuration
[18:07:46] <andypugh> JT-Shop: You may be able to call hal_pin_new directly in the EXTRA_SETUP function.
[18:08:24] <JT-Shop> and it will retain the _ ?
[18:09:02] <andypugh> Yes. Otherwise how would the original pin names have got there?
[18:09:32] <JT-Shop> ok let me see if I can figure out how to use EXTRA_SETUP()
[18:12:15] <PCW> just need the script that takes a section of halcmd show pin
[18:12:17] <PCW> and makes a dummy python component with the proper I/O
[18:13:04] <PCW> bit out = led
[18:13:06] <PCW> bit in toggle button
[18:13:07] <PCW> etc
[18:15:06] <deMimsy> Alright, so this has been bugging me. I should be able to invert the axis display in AXIS by adding the following line to my ini file: "GEOMETRY = -XY-Z" however this seems to have no effect on the system whatsoever
[18:15:13] <JT-Shop> yuck this is worse than the man pages for components http://linuxcnc.org/docs/html/man/man3/hal_pin_bit_new.3hal.html
[18:15:58] <deMimsy> any ideas?
[18:17:10] <deMimsy> I have even added a negative sign for SCALE under AXIS[N] which should invert the movement of my axis, but that doesnt seem to do anything either
[18:17:26] <deMimsy> *[AXIS_N]
[18:18:22] * JT-Shop gives up on hal pin new and tries to figure out what PCW said
[18:18:46] <PCW> pcw was half joking
[18:19:26] <PCW> deMimsy: step/dir or servo machine?
[18:25:42] <deMimsy> pcw: servo machine
[18:26:31] <PCW> with encoder feedback?
[18:26:47] <deMimsy> yes, encoder feedback
[18:27:21] <PCW> so then the first thin is to get the encoder scaling correct (correct direction and scale)
[18:27:26] <PCW> thing
[18:27:58] <andypugh> JT-Shop: Owner Type Dir Value Name
[18:27:58] <andypugh> 5 u32 IN 0x0000007B sim.0.pin1
[18:27:59] <andypugh> 5 u32 OUT 0x0000007B this_is-a_pin
[18:28:16] <andypugh> http://pastebin.com/zbyvV9ZD
[18:28:45] <PCW> does the encoder read correctly?
[18:28:55] <JT-Shop> andypugh, thanks
[18:29:20] <deMimsy> yep, encoder scaling is correct. however, for the purpose of this project, i need positive encoder increments to just be displayed as negative displacement
[18:29:25] * JT-Shop can cut and paste with the best of them
[18:29:53] <PCW> so its probably not that hard to take the output of halcmd, show pin and munge it into that format
[18:31:00] <zeeshan> its the famous pin
[18:31:03] <zeeshan> 'this is a pin'
[18:31:03] <zeeshan> :D
[18:31:04] <andypugh> deMimsy: -X in Axis ought to work. Is it possible that you are editing the wrong config file. Not that I have /ever/ done that.
[18:32:05] <deMimsy> andypugh: I did double check I was editing the right config file; however -X has no effect
[18:33:20] <JT-Shop> sim_hm2.comp:16: warning: passing argument 3 of ‘hal_pin_u32_new’ from incompatible pointer type
[18:33:21] <JT-Shop> /usr/include/linuxcnc/hal.h:344: note: expected ‘volatile unsigned int **’ but argument is of type ‘unsigned int **’
[18:33:49] <andypugh> JT-Shop: Yeah, I ignored that :-)
[18:33:55] <JT-Shop> ok
[18:34:35] <JT-Shop> andypugh, ok thanks that works and now I can have more fun
[18:35:45] <andypugh> you need to be a bit careful with the indirection. I am not sure if the component always has to be a singleton. As the example uses “variable *name” for the manually-created pin I think it is actually probably OK.
[18:36:26] <deMimsy> So this page (http://www.linuxcnc.org/docs/2.4/html/config_ini_config.html) notes that the Geometery field has no effect without a rotating axis, I only have the X, Y, and Z axis enabled in trajectory. Do I need an A,B, or C axis as well?
[18:37:07] <PCW> deMimsy: what is it you are trying to do?
[18:38:11] <deMimsy> simply change the sign in front of the X and Z outputs that is shown in the AXIS DRO tab
[18:38:59] <deMimsy> essentially just invert the display of the axises
[18:39:32] <andypugh> G10 L10 R180 ?
[18:41:06] <deMimsy> That would only work if I ran it as an MDI command everytime after homing
[18:41:22] <deMimsy> and doesnt seem to change the display
[18:41:42] <andypugh> Sorry, I always get them mixed up. expected ‘volatile unsigned int **’ but argument is of type ‘unsigned int **’
[18:41:52] <andypugh> And I can’t copy and paste from a VM either....
[18:42:18] <andypugh> G10 L2 P1 R180 just did what you might want for me.
[18:42:38] <deMimsy> did you run it as an mdi command?
[18:42:43] <andypugh> Yes
[18:43:37] <andypugh> The cursor keys still move the tool as expected, but the numbers go the other way.
[18:52:34] <deMimsy> andypugh, aright, ran it on my system and it seems to do exactly what I need, thanks!!!
[18:53:16] <deMimsy> and it should hold inbetween instances of running....just wondering if it is going to change anything else later down the road
[18:53:33] <deMimsy> or worse, anything else I already implemented
[18:53:45] <andypugh> I am not sure, and you would need to check that it has the right effect as far as G-code motion is concerned.
[18:53:46] <deMimsy> but thank you so much!
[18:55:30] <deMimsy> Currently all my gcode is prefaced with G53, just as a precaution
[18:55:43] <deMimsy> so i dont think it will change any of that
[18:55:53] <deMimsy> just worried about homing sequences...
[18:56:03] <deMimsy> but those seem to be fine for now
[18:56:59] <andypugh> Not knowing why you want what you seem to want it is hard to tell if coordinate rotation is the real answer.
[19:01:18] <andypugh> Night all
[19:51:04] <XXCoder> ot last of my electrics package
[19:51:17] <XXCoder> the oh shit button and limits
[20:29:03] <PetefromTn_> Hey Folks..
[20:29:17] <XXCoder> yo
[20:30:22] <PetefromTn_> yoyo
[20:30:35] <PetefromTn_> I got a visit from the Brown Santa today LOL
[20:31:45] <PetefromTn_> I am an airgun junkie and I bought a nice clean used rifle from an airgun classifieds site.
[20:32:18] <PetefromTn_> Just got it here and it came packaged in the original box and it is SWEET!
[20:32:51] <PetefromTn_> Been shooting it across the shop at about 12 yards and it is pretty impressive so far.
[20:33:18] <PetefromTn_> Still got a LOT of work to do to it and the trigger needs to be adjusted it is lawyer heavy.
[20:33:58] <PetefromTn_> I also got some new parts for the CNC. I managed to blow up my damn 24v power supply the other day screwing with the spindle motor fan like a dumbass.
[20:34:14] <PetefromTn_> Got a brand new on here as well as some new relays I needed.
[20:34:28] <PetefromTn_> It was like Christmas at my house this afternoon hehe
[20:49:36] <PetefromTn_> Well Gn8 folks.
[22:02:54] <zeeshan> jdh you there?
[22:08:52] <zeeshan> http://i.imgur.com/Is0LpSD.jpg
[22:08:59] <zeeshan> http://i.imgur.com/EgV83V7.jpg
[22:09:01] <zeeshan> so thats what im dealing with
[22:09:02] <XXCoder> hey
[22:09:06] <zeeshan> i think im gonna make a long ass plate
[22:09:10] <zeeshan> that cantilevers off the carriage
[22:09:18] <XXCoder> why buy so long screw?
[22:09:47] <zeeshan> so it doesnt have to ride within the slot
[22:09:50] <zeeshan> cause it doesnt fit in there
[22:09:55] <XXCoder> ah
[22:10:04] <zeeshan> http://i.imgur.com/nw7kPgh.jpg
[22:10:08] <zeeshan> it doesnt work too well at all
[22:10:14] <XXCoder> oh you got any link that explains how to grease up SBR bearing blocks?
[22:10:32] <zeeshan> sbr is the one without balls in it
[22:10:32] <zeeshan> right
[22:10:49] <XXCoder> no its supported rod type
[22:10:57] <zeeshan> yea but it has no ball bearings in it
[22:11:00] <XXCoder> its blocks has bearing balls
[22:11:11] <zeeshan> oh
[22:11:37] <XXCoder> be back in few mins
[22:11:42] <zeeshan> i dont see em being too different than normal ball screws
[22:13:49] <zeeshan> the machines at work had a different lube for way and different lube for ball screws
[22:13:53] <zeeshan> i know it wasn't grease
[22:14:01] <zeeshan> it was viscious oil of some sort!
[22:14:31] <zeeshan> http://www.thomsonlinear.com/downloads/articles/design_engineer_guide_selecting_lubricant_ball_screws_taen.pdf
[22:16:31] <zeeshan> looks like grease would work as well :P
[22:27:35] <XXCoder> thanks
[22:29:38] <XXCoder> its for ballscrews
[22:30:12] <XXCoder> http://i01.i.aliimg.com/wsphoto/v0/657536387/2pcs-25mm-SBR25-1000mm-Linear-Bearing-Rails-4pcs-SBR25UU-Linear-Motion-Bearing-Blocks-kit.jpg_350x350.jpg
[22:30:15] <XXCoder> this is sbr
[22:47:10] <Connor> zeeshan: Looks like the but fits to me...What's the problem ?
