Back
[04:40:15] <XXCoder> everyones here.
[04:55:19] <jthornton> I'm here
[04:55:34] <XXCoder> heh whats up
[04:56:15] <jthornton> get concrete formed up tomorrow or tuesday
[04:56:50] <XXCoder> why quite large gap?
[04:57:27] <jthornton> one of his guys is taking a long weekend
[04:57:35] <XXCoder> ahh
[04:58:07] <jthornton> I still have a few spots that are 1" to 2" high I have to worry down
[04:58:44] <XXCoder> fun
[05:00:36] <XXCoder> wow
http://futurism.com/chemists-accidentally-created-a-new-shade-of-blue-now-what/
[05:00:58] <jthornton> I'll just be glad when I'm done with the dirt work
[05:03:09] <XXCoder> i bet yeah
[05:03:42] <jthornton> I got a lucky break on the press brake, the die support I had to machine the slot in two setups and it was bowed so the slot was not straight
[05:04:06] <jthornton> pressed it in the H frame press till it was straight and now the die fits in
[05:04:52] <enleth> so it's true - if in doubt, use more brute force
[05:04:55] <XXCoder> nice :) so what ya planning with brake
[05:06:03] <jthornton> a carrier for the spyder, all the ones out there you need a $600 trailer hitch to use mine is NHR No Hitch Required
[05:08:19] <XXCoder> cool
[05:08:20] <jthornton> http://spyderstore.com/index.php?route=product/category&path=66
[05:08:28] <jthornton> that's a prototype
[05:08:36] <yasnak> xxcoder, you must sleep as little as me
[05:08:41] <XXCoder> that your company website
[05:08:51] <XXCoder> yasnak: I sleep around 7 hours or so
[05:08:55] <jthornton> yea that's one of my web sites
[05:09:01] <XXCoder> cool
[05:10:01] <jthornton> this is my best seller
http://spyderstore.com/index.php?route=product/product&path=60&product_id=51
[05:10:43] <XXCoder> you make all parts?
[05:11:18] <jthornton> I get the dash mount laser cut I make the rest
[05:11:59] <XXCoder> cool :)
[05:12:12] <XXCoder> I guess its not metal? can laser cut metal?
[05:12:18] <jthornton> I'll get the NHR Carrier laser cut too once I make a couple
[05:12:27] <jthornton> 11ga steel
[05:13:31] <XXCoder> next months going to be hell :(
[05:14:05] <XXCoder> jthornton: this month large areas in usa is over 100f, and fairly large areas 110f
[05:14:25] <XXCoder> small areas even hotter
[05:14:32] <XXCoder> where I live dodged that
[05:17:50] <jthornton> yea it's hot after about 11am here
[05:18:34] <XXCoder> lol

[05:41:26] <Deejay> moin
[05:45:21] <jthornton> morning
[08:22:01] <archivist> ebay sellers are silly
http://www.ebay.co.uk/itm/STUNNING-GLEDHILL-BROOK-TIME-RECORDER-CLOCK-/322165587308
[08:22:04] <archivist> worked but only for 2 hours so will require some attention
[08:24:15] <skunkworks> I am sure it just needs to be oiled
[08:24:18] <skunkworks> ;)
[08:25:39] <archivist> or put in beat or totally worn out
[08:26:04] <archivist> I have one was just checking the value
[08:29:45] <archivist> clocks can get to
http://www.collection.archivist.info/searchv13.php?searchstr=pivot+pd and then they run for a couple of hours or less
[08:41:00] <cradek> archivist: oh those are fine, just add weight and it'll run again
[08:41:39] <archivist> heh seen too many clocks where that had been done :)
[09:07:20] <bschiett> hi!
[09:07:55] <bschiett> anyone here? i have a newbie question about linuxcnc and touch off/g49
[09:10:03] <gregcnc> usually several listening, ask away
[09:11:01] <bschiett> thx
[09:11:18] <bschiett> i am using fusion 360 to do the cam programming for the router i set up a while ago (linuxcnc controlled)
[09:12:13] <bschiett> i have been noticing that depending on the order in which i load my program in linuxcnc and touch off, that it will ignore the touch off i did when i run the program
[09:12:25] <bschiett> for example, suddenly there is a 2mm offset in the z axis
[09:12:56] <bschiett> what i normally do is have different operations in different g code files (one per tool since i have to manually change tools and touch off)
[09:13:25] <bschiett> so i load a g code file, touch off xyz, then press run, it asks for the tool and i press continue since the tool is already loaded
[09:13:52] <bschiett> and then when done, i might load another file, same tool or not, touch off if necessary and run, and press continue
[09:14:24] <bschiett> in my tool table i have nothing filled in for x/y/z since i don't have a tool offset (i'm touching off to the workpiece, fixture or whatever)
[09:14:35] <bschiett> i only have the diameters of the tools in the tool table
[09:15:56] <bschiett> g code here >
http://pastebin.com/Ep0gJMXJ
[09:16:12] <gregcnc> do you let the programs finish?
[09:16:25] <bschiett> on this program i noticed the x/y touch off shifted by 2mm so it doesn't seem to be an issue only related to z touch off
[09:16:40] <bschiett> @gregcnc not necessarily no
[09:17:00] <gregcnc> I ran into this when stopping programs early, I never really tracked down what actions caused it. but if i estopped touch off needed to be repeated
[09:17:06] <bschiett> @gregcnc i might stop after finishing a workpiece in the fixture (fixtrue has 2 pockets / workpieces)
[09:17:37] <bschiett> @gregcnc hmm i see..
[09:17:51] <gregcnc> which version are you running?
[09:18:11] <bschiett> @gregcnc let me run to the maching to find out ... brb
[09:18:20] <bschiett> @gregcnc program has this line in it, btw: N60 G43 Z33.09 H1
[09:18:26] <bschiett> not sure if G43 eliminates touchoff or not
[09:18:55] <gregcnc> no it calls tool length offset from the table
[09:20:24] <bschiett> ok i am running axis 2.6.4
[09:20:44] <bschiett> i downloaded linuxcnc image and put it on a flash drive, i've been running that and haven't installed any upgrades
[09:22:06] <gregcnc> I think this may have gone away when i went to 2.7, but I can't be certain because i changed the way I did things
[09:23:34] <bschiett> hmm
[09:24:13] <bschiett> what is the correct way to upgrade given that i started out with an image i put on a flash drive?
[09:24:32] <bschiett> want to make sure i don't lose my machine config etc
[09:25:17] <gregcnc> make backups to be safe
[09:25:58] <bschiett> ok
[09:26:15] <gregcnc> I don't know the details of upgrades i just use synaptic
[09:26:22] <bschiett> ok
[09:26:36] <bschiett> it will update axis and all linuxcnc specific packages?
[09:26:47] <bschiett> i thought it would just handle general linux packages
[09:27:02] <gregcnc> yes. you'll have to point it to the 2.7 libraries
[09:27:58] <gregcnc> scratch that current release 2.7 should be there
[09:29:22] <bschiett> k
[09:29:48] <gregcnc> what i'm unsure is, if hal etc. will need updates with 2.7
[09:29:50] <bschiett> it won't pick the wrong kernel, correct? i understand there is a RT kernel being used.
[09:30:11] <gregcnc> don't update the system, just linuxcnc
[09:30:16] <bschiett> ok
[09:35:52] <bschiett> thanks a lot for the tip
[09:35:59] <bschiett> maybe this will solve the problem
[09:36:17] <bschiett> i wish i could really confirm if this is due to 2.6.4 or due to myself not understanding how to do things in the right order...
[09:38:11] <gregcnc> I remember being just as confused, and it started after an upgrade from a much older version.
[09:41:58] <gregcnc> I like the showcase on the the site. I hadn't seen it yet. and 2.7.5 was released last week.
[09:42:48] <bschiett> yeop
[09:42:50] <bschiett> yep
[09:43:00] <bschiett> can the package manager upgrade the software directly to 2.7.5 ?
[09:44:11] <gregcnc> it should
[09:44:28] <bschiett> great
[09:44:30] <bschiett> thanks
[09:46:40] <gregcnc> http://linuxcnc.org/docs/2.7/html/getting-started/updating-linuxcnc.html
[09:54:51] <bschiett> @gregcnc tty later, thanks for helping!

https://www.kickstarter.com/projects/1090944145/fr4-machine-shield?ref=category_newest
[12:47:25] <CaptHindsight> "The FR4 is a 3 axis shield, cape, or hat" I still prefer poncho, pashmina or serape
[12:48:27] <gregcnc> i have no idea what they are saying
[12:49:02] <archivist> they are saying buy this shite
[12:49:03] <CaptHindsight> https://ksr-ugc.imgix.net/assets/012/928/312/0005d17bad625afdc42ef45ba11b907f_original.jpg?w=680&fit=max&v=1467402311&auto=format&q=92&s=08d3186ec2bd84a65e845c1a2cb9e57b air bearing spindle
[12:49:31] <gregcnc> it's a shaft adapter
[12:49:39] <CaptHindsight> liars, stupid or both
[12:50:14] <archivist> I think that is a tool changer/taper socket
[12:50:39] <gregcnc> yes, mounts to spindle motor
[12:50:59] <gregcnc> maritool is making the tool hlder
[12:51:41] <archivist> but the structural design......
[12:51:44] <gregcnc> the idea of soldering the frame together is curious
[12:51:45] <CaptHindsight> an avg of $372 from each supporter
[12:52:19] <archivist> supporter/mug
[12:52:48] <CaptHindsight> just wait until I kickstart the "Make your own baby" shield, cape, etc
[12:54:48] <gregcnc> this may be practical. if a cartridge is $39, the handle is way overpriced
https://www.kickstarter.com/projects/zafirro/zafirro-sapphire-blade-razor
[12:55:31] <gregcnc> i'll wait until they give away handles to make money on refills
[12:57:08] <archivist> some seriously bad page loading times
[12:57:24] <gregcnc> better buy when it loads they might run out
[12:57:44] <gregcnc> was bad here too
[12:58:54] <gregcnc> hot enough that I might make my noon coffee on ice
[12:59:52] <archivist> I have more sense than buy polished turds
[13:01:43] <archivist> must lose some scruples so I can start selling them :)
[13:02:25] <CaptHindsight> are they just anodizing an aluminum blade?
[13:06:48] <archivist> dunno I never read the page
[13:07:41] <archivist> but I would never have expected anodising to hold an edge
[13:11:14] <archivist> image of the "real" thing show it as transparent which is correct for pure saphire
[13:19:06] <CaptHindsight> transparent aluminium
[13:19:49] <archivist> I have a bit of HP microwave made on saphire
[13:21:46] <SpeedEvil> archivist: Err - isn't pure sapphire never transparent because that's corundum?
[13:21:57] <SpeedEvil> Pure AlO is clear, but sapphire is not pure AlO
[13:22:22] <SpeedEvil> In the same way that pure water is not lemonaid.
[13:23:13] <archivist> they also use it on posh watch glasses
[13:23:27] <archivist> so you can see the dial :)
[13:24:03] <archivist> ruby being the impure version
[13:25:04] <CaptHindsight> a simpler and cheaper way would be to anodize the edge of an aluminum blade
[13:26:49] <archivist> except anodising is not a crystal but a bunch of hard blobs
[13:27:12] <SpeedEvil> wikipedia agrees with me that sapphire isn't clear. But ...
[13:28:21] <CaptHindsight> clear vs cloudy also depends on if you're examining a 10nm thick vs 1mm sample
[13:29:19] <SpeedEvil> Diamond blades do exist
[13:29:23] <archivist> I say clear
http://www.sapphires.com.cn/sapphire/view.asp?articleid=129
[13:29:27] <SpeedEvil> they are not noticably cheap
[13:29:30] <CaptHindsight> shaving isn't really hip right now
[13:29:48] <CaptHindsight> what they should making is lumberjack beard products
[13:29:50] <archivist> I dont understand shaving either
[13:33:56] <gregcnc> anodize doesn't like sharp corners
[13:40:34] <CaptHindsight> gene therapy for facial hair, stops or stunts the growth of hair until you want it back again
[13:49:32] <archivist> synx508,
http://wiki.linuxcnc.org/cgi-bin/wiki.pl?Case_Studies
[13:49:43] <synx508> ta
[13:50:30] <archivist> there is some very big iron under linuxcnc
[13:51:36] <archivist> heh and that page is over 2 years old, skunkworks add your toys
[13:52:02] <cradek> that second link seems broken, but it's a mill I helped tune that has a table you and all your friends can put a dining room table on and have a dinner party
[13:52:23] <CaptHindsight> I'm putting it on no iron today, mostly plastic with a single axis stamped steel Z positioner with screw threads
[13:52:44] <CaptHindsight> the other 2 axis are galvos
[13:54:24] <synx508> archivist, I can't remember the machine's name, think it's korean, something 40, from the mid 1990s? Anyway, I've looked after its computer since around 1997 and am fed up with it.
[13:54:35] <CaptHindsight> http://us.xyzprinting.com/us_en/Product/Nobel-1.0 converting this to Linuxcnc for a demo
[13:54:57] <CaptHindsight> only $1k at Walmart
[13:55:45] <archivist> synx508, quite a few in here have retrofitted old hardware with new linuxcnc controls, often using the original servo drives
[13:57:52] <synx508> archivist, I don't know if this is the usual design, but the servo motor drive FETs live in a big box on the side of the machine that's connected by fibre to the PC box, which also has the logic that deals with feedback from the encoders
[13:59:09] <archivist> I personally not seen that
[13:59:35] <archivist> but the isolation is a good idea
[14:01:05] <synx508> archivist, anyway, it's hard to fault find, the DOS software isn't helpful when things break. And the only networking it has is DOS Workgroup Connection which means we have a netbeui enabled Windows xp vm!
[14:01:48] <archivist> ew
[14:02:43] <synx508> it is "not ideal"
[14:03:02] <cpresser> if its still operational you can hook a scope to the signal lines to understand how its working. then reverse engineer it.
[14:03:10] <synx508> if you don't mind I'll lurk here and see what I pick up.
[14:03:45] <synx508> cpresser, I was planning on scoping the encoders and figuring it all out that way. There's no documentation of course
[14:03:45] <archivist> here is a user that likes old iron
https://www.youtube.com/user/samcoinc
[14:04:50] <synx508> woah, all the tools!
[14:04:59] <synx508> that's cool
[14:06:47] <archivist> it is a good channel for lurking and cnc
[14:09:22] <CaptHindsight> synx508: bad controls are most often turn machines into Linuxcnc projects
[14:09:45] <CaptHindsight> bad controls are what most often turn machines into Linuxcnc projects
[14:10:53] <synx508> there were two machines roughly the same, but one was sold to make room for the Datron. So no longer possible to do the quickest form of faultfinding, swapping stuff
[14:11:42] <archivist> once you do a retrofit, you know the control a lot better
[14:12:22] <synx508> I bet you do!
[14:13:25] <archivist> even easier after a few :)
[14:15:00] <synx508> it's a YCM-40 with Centroid controls. I have remembered, while feeding the cat.
[14:19:59] <archivist> something like
http://www.cnczone.com/forums/knee-vertical-mills/90643-cnc.html
[14:20:36] <synx508> yes, but smaller, wondering it's it a YCM-lower number
[14:20:50] <synx508> thought it was 40, but now checking others
[14:24:24] <synx508> yes, it's a 40 but with a smaller bed than in that photo
[14:26:56] <synx508> looks like centroid M400
[14:27:35] <synx508> which seems weird, because it says here they started making them in 1996 and I am sure it was a used machine back in 1998 and it looked years old. But maybe that was deceptive
[14:29:02] <archivist> some machines get used some abused
[15:32:02] <Lapin> Anyone have an idea for an affordable tool that'd be able to neatly make U-bends this small? (2mm gap, 2mm overhang or so) (
http://www.bhphotovideo.com/images/images500x500/Bracket1_VISLCS1_Cold_Shoe_1_515367.jpg )
[15:35:47] <_methods> nope
[15:36:02] <_methods> those bends are not going to be something simple
[15:36:19] <SpeedEvil> Lapin: A vice, bend at 90 degrees, to make a U, insert a flat bar, and hammer.
[15:36:49] <Lapin> Would there be a not-simple way?
[15:37:03] <_methods> there is nothing simple about that part
[15:37:07] <Lapin> I can't see the hammer way making it a very neat looking part...
[15:37:35] <SpeedEvil> It actually can.
[15:37:38] <Lapin> But I mean, what tools should I be looking into, how would it originally have been created? It's a common part even in cameras from 1940s and onward
[15:37:42] <_methods> you could maybe bend 2 separate pieces then weld them on
[15:37:42] <SpeedEvil> But it does require a modicum of skill
[15:37:48] <Lapin> Hmm, time to get a vice.
[15:37:50] <_methods> it was stamped
[15:38:34] <_methods> progressive dies or a more complicated 1 hit die
[15:38:44] <SpeedEvil> yeah - the countersinks are clearly deeper than the material
[15:40:05] <Lapin> Hmm, didn't know you could do a U die
[15:40:19] <Lapin> But that would make sense, as die-tooling was common for the rest of the camera, too
[15:40:29] <SpeedEvil> If you start with a [_____] bit - then it's almost easy to make
[15:40:43] <SpeedEvil> if you could make that in long lengths
[15:40:46] <_methods> well i guess you could do it with a regular press brake between a punch window
[15:41:01] <_methods> yeah it's possible with some modified tooling on a regular brake
[15:41:11] <SpeedEvil> That is going to require a progressive bendy thing that I don't know the name of with lots of bearings.
[15:42:00] <Lapin> Thanks for the input
[15:42:07] <_methods> http://www.ukb-gmbh.de/fileadmin/images/bild-rotax-1.jpg
[15:42:15] <_methods> something like that
[15:42:16] <SpeedEvil> Are you trying to make ten or a hundred thousand?
[15:42:30] <_methods> but smaller
[15:42:53] <Lapin> I'm trying to make about 50.
[15:44:06] <_methods> that is a pretty tight 180 though
[15:44:08] <JT-Shop> progressive die
[15:44:12] <_methods> a window might not even help you
[15:44:27] <_methods> yeah i'd go progressive
[15:44:32] <Lapin> Would turning that 180 U into a 2mm curve work?
[15:44:35] <_methods> but i'm assuming you could make a fancy 1 hitter
[15:44:37] <Lapin> i.e. bend it along a 2mm pin?
[15:44:48] <_methods> how would we know
[15:44:55] <_methods> we have no idea what the application is
[15:45:03] <JT-Shop> might bend around a 2mm plate depends on the material
[15:46:19] <Lapin> It's a part in which viewfinders and strobes of cameras fit
[15:46:51] <SpeedEvil> Do you have the parts to which it must fit - or have you been asked to copy it?
[15:47:04] <Lapin> I have the parts to which it must fit
[15:48:00] <SpeedEvil> carefully measuring to see what radius you can manage would be the first step then
[15:48:07] <Lapin> The upper lip's inside dimensions keep the viewfinder or strobe in place, so the outer edges of the bracket don't matter much, shape-wise
[15:49:23] <Lapin> I was just hoping there was a specific tool I was missing out on in my research that could do this, though, so I'll reconsider how to go about it a bit more
[15:49:26] <Lapin> Thanks for the input
[15:50:47] <_methods> http://i.imgur.com/r8SovyL.png
[15:50:56] <_methods> you could do something like that with a press at home
[15:51:08] <Lapin> Thanks for the drawing
[15:51:09] <_methods> make a bottom die and a top punch
[15:51:15] <_methods> press it down then hammer the edges over
[15:51:24] <_methods> i mean that's a very crude lol drawing
[15:51:29] <Lapin> Maybe if I can find some alu U-profile in the right size it would be even easier
[15:51:33] <_methods> but i just tried to slap that together real fast
[15:51:45] <Spida> Lapin: for 50 it might still be cheaper to buy them, though, if you count your time
[15:51:54] <_methods> yeah i'd just buy them personally
[15:52:01] <Lapin> True, but I'd like to be able to do this in the future, too.
[15:52:06] <Lapin> Plus they're 13$ each
[15:52:33] <Lapin> Half of the pleasure of making cameras is learning the how. :)
[15:57:44] <_methods> well there is nothing wrong with that for sure
[15:58:25] <XXCoder> lol

[15:59:06] <SpeedEvil> At that size, machining from solid might not be quite insane if you have a mill

https://www.amazon.com/dp/B0093Y88SK/ TB6560 boards!!
[17:52:41] <Magnifikus> anyone using the xhc hb304 has problems with the wheel jumping back and forth?
[17:52:56] <Magnifikus> seems to be a shitty encoder
[17:53:06] <Magnifikus> or the micro is somehow shitty programmed
[17:53:38] <Magnifikus> oh this xhc-hb04
[17:58:31] <CaptHindsight> http://linuxcnc.org/docs/html/man/man1/xhc-hb04.1.html
[18:10:49] <Magnifikus> yeah i use the plugin, also tried the plus-minus mode and has the same problem
[18:11:07] <Magnifikus> because if nobody is familiar with the problem i will send it back
[18:11:42] <Magnifikus> pretty uncool when your axis is jumping the wrong direction
[19:24:07] <KreAture_Zzz> anyone familiar with fusion 360 and closing complex shapes ?
[19:24:33] <KreAture_Zzz> whenever I extrude or cut the object it is closed in a horrid jumble, lots of badly ordered points
[19:49:53] <enleth> KreAture_Zzz: I vaguely remember NYC CNC doing a video on something related not long ago
[19:50:11] <enleth> KreAture_Zzz: take a look through their recent uploads on YT
[20:03:09] <KreAture_Zzz> thanks enleth
[20:03:25] <KreAture_Zzz> My biggest issue is the limit of 10k triangles
[20:03:47] <KreAture_Zzz> I am working around that by splitting the model in 4 and importing each seperately
[20:03:50] <KreAture_Zzz> Then jointing again
[20:03:53] <KreAture_Zzz> seems to work
[20:16:23] <Frank_12> guys, is it so bad to have a momentary switch on 220v ac for switching on the ac contactor????
[20:18:04] <KreAture_Zzz> well
[20:18:08] <KreAture_Zzz> 1. hogh voltage
[20:18:14] <KreAture_Zzz> 2. inductive load
[20:18:21] <Frank_12> i know it is safer to have a 24vdc relay to switch the load but, is it nevcessary all the extra wiring, beeing that i need 6 momentary swuitches?
[20:18:26] <KreAture_Zzz> you'd get arching
[20:18:31] <KreAture_Zzz> probably short life
[20:18:45] <KreAture_Zzz> also, it will create noise (rf noise) every time activated or deactivated
[20:19:20] <KreAture_Zzz> a relay won't fix the noise though
[20:19:22] <Frank_12> is it inductive load if im only switching the auxiliary of the contactor?
[20:19:50] <KreAture_Zzz> hmm, I think it is still a coil?
[20:20:27] <gregcnc> switch data sheet would tell you what it can do
[20:21:28] <Frank_12> http://imgur.com/a/l6CNs
[20:21:32] <Frank_12> thats the idea,
[20:23:18] <Frank_12> i dont know if the electrons flow the same way through the switch wires and the motor wires
[20:36:37] <jdh> I have a 220v momentary for latching in the contactor on my compressor
[20:40:29] <enleth> about half of the relay logic in my Bridgeport is 110VAC
[20:40:43] <jdh> consistency is boring
[20:41:01] <enleth> there are quite a few momentary switches in there
[20:41:04] <enleth> it works just fine
[20:41:39] <enleth> mind you, this 110VAC does not power any actual loads - only contactor/relay coils
[20:41:58] <enleth> (all loads are 400V 3-phase)
[20:43:41] <enleth> that's 110VAC on the main servo/spindle power contactor, in a monostable setup with a pushbutton to latch it, all endstops, all "handwheel engaged" sensing switches and some misc stuff
[20:44:14] <gregcnc> do you actually have 110VAC in your BP?
[20:44:17] <enleth> sure the loads are inductive, being solenoid coils, but currents are low, so I don't think it's really a problem
[20:44:47] <enleth> gregcnc: yeah, there's a transformer that takes 400V (L1 to L2) and outputs 110V for the contactor logic
[20:44:57] <gregcnc> just depends on how long you want the switch to last
[20:45:03] <gregcnc> OK
[20:45:11] <enleth> they lasted 40 years just fine
[20:45:27] <gregcnc> but were probably rated for such use
[20:45:52] <gregcnc> i just powered up a 400VAC machine
[20:46:40] <enleth> actually, I had to replace one of the handwheel sensors, the NC contact started opening intermittently by itself, but it was mounted in such a way that I think it was abused mechanically
[20:47:52] <enleth> and they were the least beefy of all switches in this mill
[20:47:55] <enleth> the endstops are actually filled with oil
[20:48:07] <gregcnc> how is Orac retrofit??
[20:48:29] <enleth> I was sick for the last 1,5 weeks, so nothing changed much
[20:50:27] <enleth> it's gutted, there are rails for the sheet metal shelf everyting in the control compartment sits on, the shelf is almost done, stepper drives should arrive tomorrow
[20:51:31] <gregcnc> not much to do on the one, right?
[20:51:41] <enleth> no mesa card yet, so I'm going to borrow a chinese BOB from a milling router no one uses anyway
[20:51:58] <Frank_12> thanks for the info guys, hehe i didnt read until now
[20:52:13] <enleth> a friend is going to be in California in August or so, he'll fetch a mesa card
[20:52:34] <enleth> much better than having it go through the dickwads in customs
[20:53:44] <rene-dev_> Hi, Im having trouble with the russian probescreen, when I click the button, it moves in the wrong direction, and fails with move finished without making contact. however, If I do a O<xplus> call in the MDI it moves in the correct direction, and works.
[20:53:47] <enleth> for now there's a bit of electrical work to be done anyway - mount a DIN rail, terminate all wiring on rail terminals, and so on
[20:54:17] <Frank_12> are servomotor cables expensive?? the place where i bought my panasonic ac servos sells the cable combo for 1 motor at around 60 usd, it sounded a lot for cables thats why i didnt bought them, but are they?¿
[20:54:30] <enleth> and make a 68V power supply for the steppers
[20:55:03] <Frank_12> enleth, i did the same, a family member brought me mine, much better than trying to get the customs to actualy deliver it
[20:55:05] <gregcnc> 60VDC switcher not common?
[20:55:52] <gregcnc> yes servo cables seem expensive
[20:56:06] <jdh> in my experience, $60 is dirt cheap
[20:56:09] <enleth> Frank_12: depends. is that just a wire bundle for screw terminals, or a proper shielded cable with screw-on plugs?
[20:57:10] <enleth> gregcnc: that's one way to do that, if I find one with output adjustment within 10% I can crank it up to the max and it will be almost there
[20:57:41] <Frank_12> i didnt really saw them, but ill check them, if they are shielded then sounds ok
[20:57:49] <Frank_12> thanks
[20:57:49] <gregcnc> close enough not to matter, better than orig iirc
[20:59:37] <enleth> gregcnc: thing is, the steppers I have take up to 90, the drives up to 80V (hard to find cheap chinese drives that survive more), minus a small safety margin for back-EMF, so a tad lower than 70V seems to be the sweet spot
[20:59:59] <enleth> the original ORAC stepper drives are a piece of shit based on L298
[21:00:02] <enleth> 46V max
[21:00:09] <enleth> no idea what they actually run on
[21:01:33] <enleth> but one look at the torque curves in the motor's datasheet told me why it worked like crap
[21:02:02] <gregcnc> the motors aren't great or not enough voltage?
[21:02:13] <enleth> the difference between the 35V curve (which is what it might have been) and the 75V curve (which is the recommended voltage for those motors) is quite extreme
[21:02:45] <gregcnc> makes sense
[21:03:45] <enleth> the motors themselves aren't the best thing in the world either, but I suppose they're going to run much better on a proper voltage anyway
[21:03:58] <gregcnc> when was that built?
[21:04:39] <enleth> that particular unit? hard to say, ORAC had a pretty long production run and there were quite a few revisions
[21:04:52] <enleth> some even had a pneumatic chuck
[21:05:06] <gregcnc> my Emco Compact 6 was 1986
[21:05:08] <enleth> I haven't really looked for a date code
[21:05:32] <gregcnc> it's on hold for other projects now
[21:06:05] <enleth> the slant bed one?
[21:06:14] <gregcnc> yes
[21:07:14] <enleth> either the photos I found show a unit with some weird accessory for a chuck, or the chuck on it is really tiny
[21:07:33] <enleth> looks smaller than ORAC's
[21:07:53] <gregcnc> if it had a tool changer the chuck has to be <85mm to clear tools fully
[21:08:09] <enleth> ah, ok
[21:08:13] <enleth> looks like it
[21:08:15] <gregcnc> probably about the same capacity
[21:08:37] <enleth> the toolchanger is similar to the one I've seen fitted to ORACs
[21:08:59] <gregcnc> ratcheting type
[21:09:08] <enleth> yep
[21:09:28] <enleth> could even be a different version of the same thing
[21:09:39] <gregcnc> though there was a bidirectional sauter of the same size
[21:10:04] <enleth> ORAC toolchanger is ratcheting
[21:10:33] <enleth> I mean, looks that way from the photos I've seen, unfortunately I don't have one
[21:10:41] <enleth> OTOH, I do have a multifix toolpost
[21:10:54] <enleth> which might be more suitable for my use case anyway
[21:11:28] <gregcnc> right, the smaller Emco are also, but the Turn 320 with Fanuc had the Sauter, even though that are the machine base
[21:11:40] <gregcnc> same
[21:12:08] <enleth> probably recommended by Fanuc or something
[21:12:30] <gregcnc> that model was for production. many are still running in shops.
[21:12:49] <gregcnc> some crazy people still ask 10,000+ USD
[21:14:09] <enleth> that's kind of insane for a machine this size
[21:14:10] <gregcnc> I think this is a Polish guy
https://www.youtube.com/watch?v=yC4et9me7RI&index=35&list=PLKx5oKDE2aqFhqTJ-1ptSiKwfhW1qaWKt
[21:16:19] <enleth> if "Zoran Nicin" is his name, I'd say Croatian
[21:16:39] <enleth> there seems to be a diacritic on top of "c" in the logo
[21:17:14] <enleth> that could be Czech or one of a few Balkan languages, and it does sound Croatian
[21:18:02] <gregcnc> Ah ok, not sure why I had that impression.
[21:19:44] <enleth> yep, Croatian
[21:20:14] <enleth> he had a discussion in Croatian with someone in the comments of another video
[21:24:29] <enleth> gregcnc: does it have an immobile tailstock?
[21:24:32] <enleth> looks like it
[21:25:20] <gregcnc> it's fixed
[21:26:21] <enleth> so unless it's got a very long quill, it's only going to be useful for a very limited set of operations
[21:27:55] <enleth> or require using long pieces of stock and retracting them in the chuck after some initial turning with tailstock support
[21:28:39] <gregcnc> length is limited so with 120mm of stroke it's still useful for a part maybe 50mm long
[21:29:27] <enleth> OK, makes sense
[21:33:43] <enleth> gregcnc: found a nicely documented rebuild/retrofit:
http://www.dieselrc.com/projects/emcocompact6/
[21:33:57] <gregcnc> lol that's mine
[21:34:06] <enleth> heh
[21:34:43] <enleth> so, yeah, it's nicely documented
[21:35:11] <gregcnc> if you ever want to know anything about the Emco 6, 120, 220, 320, 325, 155 let me know
[21:35:41] <enleth> probably not, as I have a small CNC lathe already, so the next lathe I'm going to shop for is something big and probably manual
[21:35:41] <gregcnc> thanks i tried. It' been taking far too long though
[21:36:06] <enleth> I don't see a point in owning a big CNC lathe
[21:36:22] <gregcnc> not unless you plan to make money on it
[21:36:36] <enleth> my point exactly - and I don't
[21:36:41] <CaptHindsight> what do you use when you have big parts?
[21:36:56] <enleth> CaptHindsight: a big manual lathe
[21:37:14] <zeeshan> enleth: why nort
[21:37:27] <zeeshan> use cnc lathe as manual
[21:37:28] <zeeshan> :P
[21:37:38] <CaptHindsight> I like doing manual work on CNC machines
[21:37:42] <zeeshan> same
[21:37:46] <zeeshan> there is no arguement
[21:37:50] <zeeshan> i dont know why ppl still argue
[21:37:57] <zeeshan> cost and skill is prolly valid arguement
[21:37:57] <zeeshan> s
[21:38:04] <gregcnc> capthindsight did they trip phases over there? cable internet went out for a half hour after
[21:38:06] <CaptHindsight> they are used to arguing
[21:38:18] <zeeshan> gregcnc: machine me this stainless parts
[21:38:18] <zeeshan> ;[
[21:38:19] <CaptHindsight> gregcnc: nothing here
[21:38:37] <enleth> zeeshan: cost
[21:38:46] <zeeshan> fair enough
[21:39:21] <gregcnc> zee is your' running yet?
[21:39:23] <enleth> zeeshan: I could get a nice huge manual lathe for 1/10 of the cost of a nice huge CNC lathe, even retrofitted in my own free time
[21:39:38] <zeeshan> gregcnc: no
[21:39:39] <enleth> well, maybe 1/5 if I did the retrofitting
[21:39:40] <zeeshan> lots of projects
[21:39:42] <zeeshan> this winter
[21:39:51] <zeeshan> but idid sign a contract to make 800 vapes by the end of this year
[21:39:52] <gregcnc> saw your crazy elbow
[21:39:58] <zeeshan> so i dunno if i can still cnc the lathe this winter
[21:40:19] <zeeshan> i really want to :(
[21:40:23] <zeeshan> gregcnc: make it for me!
[21:40:33] <zeeshan> plz ;[
[21:40:33] <gregcnc> mount four routers to your mill
[21:40:43] <enleth> zeeshan: besides, so far all big stuff I've ever needed turned was the kind of stuff Abom79 does - I don't want to use the word "unsophisticated" out of respect to him, but I can't find a better term. just not stuff you really need a CNC for.
[21:40:53] <zeeshan> lol enleth
[21:41:13] <zeeshan> yea if youre just turning threads
[21:41:14] <zeeshan> facing
[21:41:16] <zeeshan> making grooves
[21:41:23] <zeeshan> on one offs, i dunno if a cnc lathe is worth it
[21:41:25] <enleth> or long straight shafts
[21:41:25] <zeeshan> even in manual mode
[21:41:32] <zeeshan> seems like a waste of money
[21:41:35] <enleth> yep
[21:41:50] <zeeshan> but those guys who are using those ancient tracer attachements
[21:41:52] <zeeshan> just drive me insane
[21:41:53] <zeeshan> lol
[21:42:00] <zeeshan> like keith fenner
[21:42:10] <zeeshan> i love watching those guys machine
[21:42:18] <zeeshan> but it drives me also insane because they run their machines SO SLOW
[21:42:24] <zeeshan> i run at 25x the speed
[21:42:28] <gregcnc> when do you guys have time to watch other people make stuff
[21:42:31] <zeeshan> (not exagerrating)
[21:42:37] <zeeshan> gregcnc: before bed time
[21:42:42] <zeeshan> i watch 30 min
[21:42:53] <zeeshan> or during lunch at work
[21:43:15] <gregcnc> good use of lunch break
[21:43:24] <enleth> well, Abom does use cuts that are much more agressive than I'd have dared to run on CNC, so it probably ends up taking about as fast as playing it gentle with multiple passes
[21:44:10] <enleth> but he's using machines that are sized appropriately for their operator
[21:44:28] <gregcnc> or application
[21:44:46] <gregcnc> though he is a big dude
[21:46:12] <gregcnc> has witnit been around, he found a big cnc clausing for next to nothing and setup on linuxcnc
[21:47:29] <enleth> a let's-pretend-it's-not-a-bridgeport-clausing or a bed mill clausing
[21:48:36] <gregcnc> lathe, 4000 CNC or something
[21:48:43] <enleth> ah, ok
[21:48:45] <gregcnc> time is up for me tonight, later
[21:49:22] <gregcnc> zeeshan, 12ga sheet and ball peen hammer, good luck
[21:49:28] <CaptHindsight> gregcnc: any interest in my Matsuura 710?
[21:49:54] <gregcnc> i have no space left
[21:50:08] <CaptHindsight> it's only the size of a large car
[21:50:33] <gregcnc> yeah my wife complains there are 2 cnc and my car in the garage already
[21:51:15] <CaptHindsight> you need a larger garage is all
[21:51:20] <gregcnc> right
[21:51:38] <gregcnc> i'm looking
[21:52:27] <CaptHindsight> see you later
[21:56:08] <zeeshan> lol gregcnc
[21:56:19] <zeeshan> i wish sometimes i was superman
[21:56:20] <zeeshan> or magneto.
[21:56:29] <zeeshan> those bastards could easily form it to perfection in 1 min.
[22:14:46] <CaptHindsight> zeeshan: you just need 2 more axis
[22:16:14] <SpeedEvil> zeeshan: Or beer powered. Bender.
[22:58:58] <TurBoss> hi
