[00:07:50] <andypugh> The web page shows a spindle, but I don’t know why it isn’t shown fitted.

[00:11:52] <andypugh> There are some things about it to like, though I would want to know how the end-thrust on the screws was handled. I was going to comment on the work envelope, but thinking about it, it is actually more than the manual shows for my milling machine!

[00:13:46] <jdh> http://www.ebay.com/itm/201080831373
[00:14:21] <andypugh> Hmm, yes, my INI file says I have 360 x 157 x 265. And that’s normally enough.
[00:16:11] <andypugh> Ones on eBay with a spindle are more expensive, for example: http://www.ebay.com/itm/191148893869?_trksid=p2047675.c100005.m1851&_trkparms=aid%3D222003%26algo%3DSIC.FIT%26ao%3D1%26asc%3D22466%26meid%3D6533969978148947273%26pid%3D100005%26prg%3D9735%26rk%3D1%26rkt%3D6%26sd%3D201080831373&rt=nc
[00:16:28] <andypugh> Grr! I didn’t copy all of that!

[00:16:40] <andypugh> http://www.ebay.com/itm/191148893869
[00:17:01] <andypugh> And that’s got a really poor looking spindle.
[00:17:53] <jdh> did you build your wheel?
[00:18:25] <andypugh> No. The spokes haven’t turned up yet.
[00:22:19] <andypugh> I manged to fill the weekend with other jobs, like painting and filling and making rear wheel spindle components. The rear spindle is remarkably compicated, and probably not very good.
[00:22:45] <Connor_iPad> Wheel for what?
[00:23:34] <andypugh> There are a couple of hollow aluminium things go in from each side, each through a fiddly set of spacers and tensioning widgets, and then about 1” into the hollow wheel spindle, then a tie-rod (only 7/16”) goes through the whole thing.

[00:25:16] <andypugh> Also, amusingly, when you remove the spokes the hub falls apart into 5 pieces, only the spoke tension holds the parts together!
[00:26:44] <andypugh> Ironically the super-bizarre front end is simpler.

[01:41:43] <PetefromTn_Andro> Evening folks
[01:42:01] <humble_sea_bass> holla back pete
[01:42:16] <PetefromTn_Andro> Hehe
[01:42:52] <PetefromTn_Andro> What are you crazy CNC junkies up to tonight?
[01:44:01] <humble_sea_bass> look over this insane thing i've never seen before that andy posted
[01:44:06] <PetefromTn_Andro> We are supposed to be getting some nasty weather tonight but so far it is pretty calm out.
[01:44:13] <humble_sea_bass> http://www.geutskens.eu/neracar/300-wheels_assy.htm
[01:44:37] <accuartisans> we are supposed to as well! Nort GA
[01:44:41] <humble_sea_bass> http://www.geutskens.eu/neracar/index.htm
[01:45:02] <pcw_home> sort of here...
[01:45:17] <PetefromTn_Andro> Some kinda hub steered wheel assy?
[01:45:55] <accuartisans> @PCW, howdy, well i bit the bullet, got the gigabyte J1800!
[01:46:27] <accuartisans> compiling the 3.14 rt kernel right now
[01:46:48] <PetefromTn_Andro> Accurate so far it is kinda nice outside. Got the windows open but we did put my wife's trooper in the shop in case we get the hail they are squalkin about
[01:48:03] <accuartisans> they say it's going to be nasty after 12 or so last i saw before i came down to the shop and work (in the basement:)
[01:49:40] <accuartisans> @PCW, you wouldn't happen to have and BIOS setup screen shots or parameters you are using at this point would you?
[01:49:53] <humble_sea_bass> http://forecast.io/
[01:50:02] <humble_sea_bass> some bad stuff is coming our way
[01:50:38] <PetefromTn_Andro> Where are you?
[01:50:58] <accuartisans> dawsonville, ga
[01:51:03] <humble_sea_bass> nyc, by bad i mean 3 days of rain
[01:51:11] <pcw_home> No but I did have to update the BIOs to get it to boot Ubuntu at all
[01:51:37] <PetefromTn_Andro> I'm in maryville Tennessee.
[01:52:08] <accuartisans> yep, i have the F3 version
[01:52:50] -!- patrickarlt has quit [Quit: Leaving...]
[01:53:25] <pcw_home> I think the main thing is you need to select compatibility mode
[01:55:23] <accuartisans> the CSM? yeah, it took about an hour to figure that out:( It just wanted to boot into the EFI shell. The documentation sucks, but, i am impressed so far.
[01:56:02] <pcw_home> yeah it was painful to get it running the first time but the hardware is pretty nice
[01:57:01] <accuartisans> are you isolating the cpu? as a kernel flag?
[01:57:09] <pcw_home> much snappier than the Atoms...
[01:57:30] <accuartisans> and the AMD 350/450 platform!
[01:57:54] <pcw_home> No I tried but it made latency worse (it my particular environment)
[01:58:18] <accuartisans> that's the same thing i found out on the AMD 350
[01:58:21] <pcw_home> (preemt-RT/Ethernet FPGA card)
[01:58:47] <PetefromTn_Andro> Gn8
[01:58:48] <accuartisans> Yes, I have the 7i80/7i77

[01:59:13] <accuartisans> Gn8?? what's that?

[02:45:33] <Anonymoose> ive recent;y joined a local makerspace and they have a partially complete mini mill/drill with a 4 axis CNC conversion. ive installed LinuxCNC on a machine and was trying to newb my way through the setup but was stumped pretty quickly. i have a tiny bit of informaiton but was wondeirng if anyone had some experience with this sort of thing and could point me in the right direction where I
[02:45:33] <Anonymoose> can read up about it myself. the drivers are k179 and steppers are tamagawa 2.2v 4.6A
[02:47:53] <ChuangTzu> hmm
[02:47:58] <ChuangTzu> seems like i've seen you here before?
[02:48:03] <ChuangTzu> or where have i seen you?
[02:48:04] <ChuangTzu> :S
[02:48:24] <Anonymoose> me? lol i havent been on irc since the days of #vcd on efnet in like 99
[02:48:29] <ChuangTzu> huh
[02:48:42] <Anonymoose> I guess Anonymoose is just universially clever or stupid
[02:48:43] <ChuangTzu> i seriously doubt my memory is that great
[02:48:56] <ChuangTzu> yeah, there must be other such meese
[02:48:58] <ChuangTzu> :S
[02:49:10] <Anonymoose> lol, damned sweedes
[02:51:10] <Anonymoose> and ideas onthe config? there were lots of preconfigured options available, im not sure what drives my config settings. the controller or stepper or both?

[11:41:38] <Jymmm> ok, cool
[11:42:17] <Jymmm> Red Devil TSP/90 is 100% Sodium Metasilicate, and $5/LB
[11:42:44] <Jymmm> The other 70% seems to be Oxiclean
[11:43:16] <Jymmm> But, I might have found al alternative to that too (Half the price)

[11:45:56] <Jymmm> TSP/90 in 4LB bag is $11
[11:46:06] <Jymmm> Ace Hardware
[11:47:01] <Jymmm> Oxiclean is about $2/LB, I might have found at half that
[11:47:23] <Jymmm> and in 1LB jars

[17:23:31] <FinboySlick> https://www.youtube.com/watch?v=s9IdZ2pI5dA <-- wow
[17:24:21] <FinboySlick> I wonder if it's more or less energy efficient than casting (flexibility aside).
[17:27:16] -!- pilsna has quit [Remote host closed the connection]

[17:34:57] -!- larryone has quit [Quit: This computer has gone to sleep]
[17:35:26] <malcom2073> My guess would be it's more cost effective for one-offs, but less energy efficient once you get past making a couple of something
[17:36:08] <Jymmm> humble_sea_bass: I wish!
[17:39:26] <MrHindsight> they aren't concerned about efficiency the additive process allows you to make parts in one piece that can't be done by casting or machining alone, everyone really needs to start ignoring the recrap junk and really see what 3DP/additive manufacturing is about
[17:40:47] <FinboySlick> MrHindsight: I wasn't really referring to their concern, I was mostly just wondering if that would actually be efficient. You're only melting the volume that you're using and I'm assuming that lasers don't have a lot of waste heat.

[17:42:04] <malcom2073> Then what did reprap have to do with it?

[17:47:56] -!- larryone has quit [Quit: This computer has gone to sleep]
[17:50:24] <MrHindsight> the problem with the laser is that they aren't 100% efficient, so even if the heat is used more efficiently as the point of sintering much of the energy has been lost producing it

[19:02:42] <MrHindsight> yeah, all pretty low cost
[19:04:00] <MrHindsight> how much is oxyclean $2/lb?

[19:06:06] <Jymmm> Ah, 2007 vs 2009 MSDS
[19:07:08] <MrHindsight> plus anything <1% non-toxic doesn't even have to be listed
[19:08:00] <Jymmm> OxiClean $2-$5/LB
[19:08:50] <MrHindsight> yeah but it's a name brand, you're not being a good consumer buy buying off brands

[20:06:42] * JT-Shop wished that flipflop had more than 3 words in the description :(
[20:07:38] <PCW> probably written a by a damned EE

[20:08:24] <JT-Shop> exactly true and no extra fluff

[20:08:40] <PCW> well hardware types swim in D FFs
[20:09:49] <PCW> so if set and reset are both false the output takes the value of the D pin on the rising edge of the clock
[20:11:27] <JT-Shop> what I have now is an and component that has motion.motion-enabled and digital-out as inputs and the out drives an output pin on the 7i76
[20:11:57] <JT-Shop> when they press the estop the motion.motion-enabled drops out and the spindles go off

[20:12:31] -!- `Nerobro [`Nerobro!fwuser@globalcom.global-com.com] has joined #linuxcnc
[20:12:38] <JT-Shop> but when they press the power button they come back on... and that is what I'm trying to solve how to not have the spindles start back up
[20:13:17] <PCW> what should re-enable the spindles ?
[20:13:46] <JT-Shop> that's the sticky part
[20:14:13] <JT-Shop> an off to on transition from digital out would be correct I think
[20:14:45] <PCW> OK so digital out goes in to flip flop clock
[20:15:00] <JT-Shop> ok
[20:15:38] <PCW> and not motion.motion-enabled goes into reset
[20:16:15] <JT-Shop> that makes sense
[20:16:42] <PCW> and D is either tied high (setp) or used as an additional enable
[20:17:20] <JT-Shop> D == data I think
[20:17:45] <PCW> yes (doing this from man page memory)
[20:18:53] <PCW> so to get a high output you need:
[20:18:54] <PCW> reset low
[20:18:56] <PCW> data high
[20:18:58] <PCW> rising edge of clock
[20:19:50] <PCW> as soon as you assert reset (motion.motion-enabled going away)
[20:19:52] <PCW> you need to go through the same sequence to set the output high again

[20:46:48] <Anonymoose> I've recently joined a local makerspace and to my surprise they had a disused CNC converted mini mill/drill machine.
[20:46:48] <Anonymoose> I am totally new to this sort of thing and had some questions I was hoping could be answered or I could be directed to appropriate 'noob' resources.
[20:46:48] <Anonymoose> I did some minor fixing of cables and got a computer in the shop and put LinuxCNC on it. Still looking for a parallel cable.
[20:46:48] <Anonymoose> Specifications (only things I 'know'):
[20:46:48] <Anonymoose> The stepper drivers are: K179
[20:46:48] <Anonymoose> The stepper motor encoders are: Tamagawa 2.2v 4.6A
[20:46:48] <Anonymoose> The computer has LinuxCNC installed on it.
[20:46:49] <Anonymoose> Questions:
[20:46:49] <Anonymoose> - Can the handwheels be turned manually without damaging the steppers?
[20:46:50] <Anonymoose> - Is it typical to wire the X & Y endstops to the kill switch?
[20:46:50] <Anonymoose> - What is the little motor on the back of the mill power supply box for? auto on/off?

[20:53:34] <JT-Shop> with the power off sure
[20:54:13] <Anonymoose> ah ok cool, thanks. i know some people had used it in the past with the power off to the 'controller' (chips everywhere)
