[01:40:42] <zeeshan> after 3 hours of messing around
[01:40:54] <zeeshan> i think i have this mastercam postprocessor working to output correctly for linuxcnc lathe
[01:41:07] <zeeshan> i really like the new mastercam versions
[01:41:16] <zeeshan> havent used it since mastercam 8
[01:41:31] <zeeshan> it's got a crapload of tools builtin, all sorts of inserts
[01:41:39] <zeeshan> almost all of iscar's catalog is in there!
[02:02:45] <Deejay> moin
[03:37:41] <Tom_itx> zeeshan they didn't used to be that way
[03:38:42] <Tom_itx> i worked out one for smartcam some time back
[03:53:20] <SquirrelCZECH> nah
[03:53:26] <SquirrelCZECH> anybody familiar with green chinese?
[03:53:29] <SquirrelCZECH> http://www.ebay.com/itm/TB6560-3A-Driver-Board-CNC-Router-Single-1-Axis-Controller-Stepper-Motor-Drivers-/141091708480?pt=LH_DefaultDomain_0&hash=item20d9b89e40
[03:53:47] * SquirrelCZECH can't really understand what "Decay" settings he should use
[03:53:48] <SquirrelCZECH> I mean
[03:54:02] <SquirrelCZECH> I can find some exlpanations based on "high" "low"
[03:54:08] <SquirrelCZECH> but I got percentage so I am not sure :/
[03:58:59] <archivist> look in the toshiba datasheet
[03:59:46] <archivist> probably a current reduction after a time, I try not to use that at all as the torque will also drop
[04:01:07] <archivist> it should only effect holding torque when not in motion
[04:02:02] <SquirrelCZECH> ok ok
[04:02:06] <SquirrelCZECH> so, driver is setuped :D
[04:50:11] <chd> Hi! Anyone here using gmoccapy_plasma? I'm new to glade and the gmoccapy file structure and I want to change the axes display so that it shows only one decimal place (1/10mm) - because for plasma cutters 1/1000mm resolution is not useful. In which (xml?) file do I have to do the change?
[05:47:14] <Lathe_newbie> hi there
[05:47:20] <Lathe_newbie> i have a little question
[05:48:04] <Loetmichel> so spit it out
[05:48:11] <Loetmichel> dont ask to ask, just ask
[05:49:16] <Lathe_newbie> https://github.com/cdsteinkuehler/MachineKit/tree/MachineKit-ubc/src/emc/kinematics
[05:49:25] <Lathe_newbie> here are the files for the linear delta kins
[05:51:16] <Lathe_newbie> but where do i have to define the points?
[05:51:23] <Lathe_newbie> in the header file is written
[05:51:24] <Lathe_newbie> * Towers 0, 1 and 2 are spaced at 120 degrees around the origin
[05:51:24] <Lathe_newbie> * at distance R. A rod of length L (L > R) connects each tower to the
[05:51:24] <Lathe_newbie> * platform. Tower 0 is at (0,R). (note: this is not at zero radians!)
[05:51:35] <Lathe_newbie> but there are no definitions done there?
[05:51:55] <Lathe_newbie> Loetmichel: i dont ask to ask^^
[05:52:04] <Lathe_newbie> i know that i dont should do that
[07:23:26] <IchGuckLive> SquirrelCZECH: ?
[07:24:14] <IchGuckLive> has bean a bussy night here on the channel
[07:24:32] <IchGuckLive> chd: ?
[07:25:56] <IchGuckLive> hi sylphiae
[07:25:57] <chd> yes, here ;-)
[07:26:09] <IchGuckLive> i got some plasmas in use
[07:26:13] <sylphiae> hi
[07:26:22] <IchGuckLive> where are you in the world inch or metric
[07:26:37] <sylphiae> inch
[07:26:40] <chd> Germany, so metric
[07:26:50] <IchGuckLive> chd ich sitz in kaiserslautern
[07:27:00] <chd> ah, na das trifft sich :-)
[07:27:14] <IchGuckLive> chd please hit my nick for german
[07:27:35] <IchGuckLive> sylphiae: ;-) as you know yust ask
[07:28:11] <chd> yes, just a moment, i have a call
[07:28:17] <IchGuckLive> NP
[07:28:43] <IchGuckLive> its cloudy here some drops but sun as you need !
[11:22:35] <Jymmm> Interesting switch... http://www.aliexpress.com/item/10-psc-of-3-in-one-Push-Button-with-Microswitch-Game-accessory-for-amusement-machine/321606603.html?
[11:29:43] <asah> hello, have a maho schematics question. loetmichel around?
[11:30:35] <Jymmm> In regards to reed switchsl would N/O be in respect to being in contact with the magnet, or not?
[11:30:57] <asah> there is a symbol on the schematics that looks like a capacitor symbol, but can’t be. it is two solid bars next to each other. most likely a contactor or relay. labeled with code Q. any idea?
[11:31:40] <Jymmm> asah: Post it
[11:31:44] <asah> sometimes with code K. I can’t make out the difference.
[11:31:47] <archivist> a picture
[11:31:53] <asah> it looks exactly like a capacitor
[11:32:18] <asah> but perhaps closer together?
[11:32:23] <asah> ok, ok.
[11:32:24] <archivist> capacitors are unlikely to have a Q
[11:32:25] <asah> one sec
[11:32:33] <asah> it is certainly NOT a capacitor
[11:32:37] <skunkworks_> contact..
[11:33:43] <archivist> and what is it called in the parts list if you have that too
[11:34:07] <asah> https://www.dropbox.com/s/us749t46npfav88/Screenshot%202014-08-19%2009.15.06.png
[11:34:17] <asah> look at 1Q1
[11:34:28] <asah> and 7K2 and 3
[11:34:33] <asah> vs K1
[11:35:06] <Jymmm> WTH is that?! looks like shit. and wheres the rest of the schematic?
[11:35:09] <asah> I am trying to understand the logic.
[11:35:20] <asah> thats a small screenshot of it =)
[11:35:22] <archivist> hmm revolting loss of image quality
[11:35:26] <asah> =)
[11:35:35] <asah> its a copy of a copy of a copy I am sure.
[11:35:51] <asah> https://www.dropbox.com/s/hy0th1lm1nsroch/maho_400e_schematics_09.png
[11:35:55] <Jymmm> asah: doens't tells us shit, you need to post more than jsutthe symbols
[11:36:06] <archivist> the reduced it to bilevel, never a good idea
[11:36:17] <asah> well, I am trying to understand the symbol, not the circuit.
[11:36:29] <Jymmm> It's probably a connector
[11:36:43] <asah> I thought there might be someone here versed in the strangeness of german maho symbology from the 80s.
[11:36:59] <asah> on the odd chance. =)
[11:37:11] <Jymmm> like where a wiring haress breaks apart. I see it a lot in automotive. the numbers 101/13 represnet connector numbers
[11:37:11] <asah> the letter codes are not consistent.
[11:37:50] <asah> ok. I could see that.
[11:37:57] <asah> some are labeled switch block.
[11:38:03] <asah> overload protection.
[11:38:18] <asah> switch.
[11:38:32] <asah> aux switch block.
[11:38:41] <Jymmm> as example http://ww2.justanswer.com/uploads/s420/2012-03-23_024951_96_ranger_4.0_engine_control_wiring.jpg
[11:38:42] <asah> that sort of thing.
[11:39:10] <Jymmm> very bottom midle...C111 C102 both ends of the cable cable/wire
[11:39:19] <Jymmm> ^same
[11:39:44] <asah> right. ok.
[11:40:17] <Tom_shop> but.. but.. they're the same wire!
[11:40:33] <Jymmm> Tom_shop: but which end?
[11:40:43] <asah> those nums are the terminal block connection points likely.
[11:40:43] <cpresser> asah: that looks familiar. 7K2 could mean 'position 2 of clamp-block 7' (K = Klemme, German for clamp)
[11:41:13] <asah> cpresser: ah… yes, this is the sort of insight I am looking for.
[11:41:34] <asah> some kind of deeper methodology at work. =0
[11:42:41] <cpresser> usually circuit breakers (fuses) are labeld 'XFy.z' with X=Block y.z=Sub-ID. I have stickers with such a numbering-scheme on all my outlets :)
[11:44:25] <jdh> I have stickers labeled "Downstairs bathroom -maybe"
[11:44:45] <Tom_itx> sure hope the stickers don't get old and fall off
[11:44:53] <Jymmm> I just have a map
[11:44:54] <asah> stickers? nice… mostly just sharpie and masking tape over here.
[11:44:58] <archivist> I have barcode stickers :)
[11:45:35] <Jymmm> archivist: How does that work for ya when you've blown a circuit and can't see/power on your barcode reader?
[11:45:54] <archivist> who said it works!
[11:45:58] <Jymmm> lmao
[11:46:03] * Tom_itx puts up a detour for Jymmm's map
[11:46:05] <cpresser> :D
[11:46:06] <Jymmm> archivist++
[11:46:22] <archivist> I only use them for the archive
[11:46:50] <Jymmm> Tom_itx: You'll have to do better than that =)
[11:56:38] <JesusAlos> hi
[11:57:15] <cpresser> thats how the numbering of plugs on my workbench looks: http://imgur.com/HMHDVOw
[11:58:46] <LeelooMinai> Must be nice living in a country where plugs don't fall by themselves from sockets:)
[12:00:24] <JesusAlos> I still looking for a fin who indicate the speed in mm/min
[12:00:53] <JesusAlos> but only found motin.current.vel who show the speed in units machine/min
[12:01:38] <JesusAlos> need the hal pin of speed in mm/min
[12:03:06] <archivist> you can connect it to a scale comp to do that
[12:08:30] <JesusAlos> ok, so there are no pin who show it directly
[12:11:21] <Loetmichel> asah: here. but i have no idea about maho
[12:11:28] <JesusAlos> archivist: you mean must beload hal component and multiplicate units machines
[12:22:34] <Loetmichel> *gnah* took me about 1.5 hrs to get home for 12 km... courtesy to the american/english pilots that couldnt aim right in ww2... they found a half-ton dud bomb on my way home...
[12:26:49] <zeeshan> is it normal to have iscar's entire tool holder and inserts catalog
[12:26:53] <zeeshan> within a cam program? :P
[12:30:08] <archivist> zeeshan, think iscar advertising
[12:31:32] <zeeshan> nooo
[12:31:40] <zeeshan> you can click literally any insert
[12:31:45] <zeeshan> and it automatically draws it up for you
[12:32:04] <zeeshan> for example, im using tnmg332 inserts
[12:32:11] <zeeshan> for my facing tool
[12:34:15] <archivist> and that means you will start buying iscar inserts...yes
[12:34:21] <zeeshan> no
[12:34:31] <zeeshan> cause that exact model is made by sandvik and mitsubishi
[12:35:12] <archivist> I know most are standard, but teh speshels...
[12:36:56] <IchGuckLive> hi all B)
[12:37:56] <zeeshan> http://i.imgur.com/W0AvUwa.png
[12:38:14] <zeeshan> its so tripping looking at mcam in solidworks
[12:38:17] <zeeshan> *trippy
[12:38:39] <zeeshan> archivist: is your lathe setup so +X is towards you
[12:38:46] <IchGuckLive> solid works best with mastercam
[12:38:59] <zeeshan> IchGuckLive: i havent used mastercam since version 9
[12:38:59] <zeeshan> lol
[12:39:04] <zeeshan> so this is a big difference!
[12:39:19] <zeeshan> i change my diameter in the part and the program updates
[12:55:48] <JesusAlos> by
[15:29:07] <dr0w> Do I need a key slot on my encoder disc for the spindle?
[15:42:39] <zeeshan> dr0w: for index pulse?
[15:44:10] <zeeshan> https://www.youtube.com/watch?v=dc3Kd9QDUks
[15:44:12] <zeeshan> lathe test
[15:44:13] <zeeshan> :D
[15:47:26] <CaptHindsight> zeeshan: how about their radii? :p
[15:47:37] <zeeshan> thjeres a radius in one of the steps
[15:47:46] <zeeshan> seems like the 1/16 rad gauge fits in it
[15:47:52] <zeeshan> i shoulda made it bigger, cause i cant tell :P
[15:48:06] <zeeshan> the steps are 0.95" 0.85 .75 .5
[15:48:18] <zeeshan> and when i measure em with the micrometer, it seems to be within 2 thou
[15:48:25] <zeeshan> i want to make it more accurate :/
[15:48:48] <zeeshan> im gonna try later tomorrow with a new insert that doesnt have a chipped edge and see what happens
[15:50:43] <CaptHindsight> the similar lathe I put back together here has too much flex, I'd have to use a live center to get close to that on your same part in steel
[15:51:23] <zeeshan> but the thing is
[15:51:26] <CaptHindsight> your version must be more rigid
[15:51:36] <zeeshan> if the part is flexing, then i'd notice the parts being oversized right?
[15:51:46] <zeeshan> some of the steps are undersized
[15:51:50] <zeeshan> some are nominal
[15:52:46] <zeeshan> like the .95" measures 0.9493", .85" measures .8490", .75 measures .7501", .5" measures 0.4980"
[15:53:03] <zeeshan> so its kinda all over the place?
[15:53:22] <CaptHindsight> what is the step size?
[15:53:24] <zeeshan> thats why i feel like it has to be something like "built up edge" on the tool
[15:53:31] <zeeshan> finishing pass is 10 thou
[15:53:42] <zeeshan> rough is 30 thou
[15:53:51] <zeeshan> (depth of cut)
[15:56:30] <zeeshan> actually
[15:56:35] <zeeshan> i realized something through the program..
[15:56:56] <zeeshan> i'm in CSS mode.. what i notice is, even though the diameter is the same, the spindle is speeding up
[15:57:13] <zeeshan> because it needs some time to get to speed, yet the finishing already had started
[15:57:28] <zeeshan> so during the same diameter cut, it is seeing different SFM
[15:57:40] <zeeshan> i wonder if there is a way to wait till the spindle gets to speed before cutting
[15:59:46] <zeeshan> ah, it looks like i havent configured the "spindle at speed" thing
[16:13:22] <JT-Shop> sketching in 3D is interesting in SW
[16:18:03] <zeeshan> JT-Shop: its awesome for making roll cages
[16:18:18] <zeeshan> cause you can draw 3d lines and then just select em with the approrpiate kind of weldment
[16:19:58] <JT-Shop> yea, I just did an exhaust pipe
[16:20:04] <JT-Shop> came out pretty cool
[16:20:28] <Deejay> gn8
[16:25:06] <dr0w> zeeshan: yeah
[16:25:20] <zeeshan> yea to what
[16:25:20] <zeeshan> :P
[16:30:05] <dr0w> http://www.stevenson-engineers.co.uk/files/encoder.jpg
[16:31:01] <dr0w> This guy has another photosensor for a key slot.. I'm working on making a disc, currently no key slot.
[16:32:48] <dr0w> I drew up something similar to this one: http://www.collection.archivist.info/archive/DJCPD/PD/2013/2013_08_04_starturn_encoder/IMG_1631.JPG
[20:34:08] <PetefromTn_andro> Evening folks..
[21:18:44] <sharpen047> hey all, i was womderingif anyone could help me get video in emc. m player works with crosshairs but is slow and i would like to add the xyz offsets feature.
[22:03:25] <XXCoder> hey pete
[22:05:10] <Benjamin23> has anyone used a wired xbox 360 controller as a manual remote/control?
