[00:17:28] <RyanS> I don't know what they were trying to prove that it was something to do with the hotness scale
[00:18:08] <XXCoder2> lol yeah highest I ever went was over 200k
[00:18:14] <XXCoder2> man it was hot

[00:22:21] <Jymmm> RyanS: Am I'm syaing he already iss 100
[00:22:24] <XXCoder2> yeah after lol

[00:23:03] <RyanS> You are 100 years old?
[00:23:06] <Jymmm> century*
[00:23:19] <Jymmm> I'd say XXCoder2 is 102
[00:23:47] <XXCoder2> well I am around 100 times. ;)

[00:23:58] <Jymmm> lol
[00:24:12] <RyanS> How do you even know how to use a computer. If you are 100, and they didn't have PCs in the Normandy landings
[00:24:30] <XXCoder2> I didnt say 100 yr old, I said 100 times ;)
[00:24:59] <Jymmm> RyanS: See, he's even older than that!
[00:25:08] <XXCoder2> lol
[00:25:17] <XXCoder2> remind me of one secretly immortal person
[00:25:34] <XXCoder2> some lady asked, he said "you first"
[00:25:41] <XXCoder2> lady said she was 23
[00:25:48] <XXCoder2> he said "Hmm 45"
[00:25:58] <XXCoder2> she was surpised hes older than he looks
[00:26:15] <XXCoder2> later point of book he admint he meant hes 45 times older not just 45 years old
[00:26:38] <XXCoder2> 1034 years old
[00:26:59] <jdh> afaik, all immortal people are secret.
[00:27:42] <Jymmm> Yeah, just ask XXCoder2! He isn't a 100 TIMES 100 for nothign =)
[00:27:51] <RyanS> do you still use an overhead line shaft and steam power for machining ? :)
[00:28:03] -!- patrickarlt has quit [Remote host closed the connection]
[00:28:16] <XXCoder2> nah I now use barge converted to hime just like that highlander movie. loved the idea so copied it

[00:28:45] <Jymmm> =)
[00:29:29] <mozmck> Steam! I have an engine, overhead shafts and pulleys, and machine to hook up.

[00:42:42] <LeelooMinai> I need some input on my "idea" for making cheap but decent table for my cnc.
[00:43:03] <XXCoder2> scrap wood
[00:43:10] <Jymmm> styrafoam and duct tape
[00:43:24] <ssi> LeelooMinai: what's the new idea
[00:43:40] <LeelooMinai> I looked at many options, 80/20, mdf + t-slots, aluminum plate + just drilling/tappin holes, etc.
[00:43:51] <LeelooMinai> But except the mdf one they are too expensive
[00:44:00] <XXCoder2> whats you lookinf in sizes and such?
[00:44:15] <LeelooMinai> 500 by 530mm
[00:44:28] <ssi> LeelooMinai: when you say mdf+tslot, are you talking about putting aluminum tslot channel in the mdf? or actually cutting slots in the mdf itself
[00:45:02] <LeelooMinai> That was Connor's setup - he has alimunum slot channels in an mdf board
[00:45:36] <LeelooMinai> No, Jymmm didn't like it, and I can see why, but I found and improvement to this idea: http://www.leevalley.com/en/hardware/page.aspx?p=52400&cat=3,43576,61994,52400
[00:45:38] <ssi> k just checking
[00:45:56] <LeelooMinai> As you can see those have "wings" on the bottom so they should be better after using screws + epoxy
[00:46:14] <XXCoder2> my my plan is no more complex than simply double tape on surface
[00:46:17] <LeelooMinai> But, still, it's mdf, so I have mixed feelings
[00:46:26] <Jymmm> That is also shown nstalled in 13 layer russian plywood, not MDF
[00:46:29] <ssi> I would certainly do plywood instead of mdf
[00:46:32] <XXCoder2> I saw setups thats surface is 100% 8020
[00:46:45] <ssi> XXCoder2: yeah I've seen similar
[00:46:53] <ssi> http://woodgears.ca/pantorouter/kuldeep/buy.html
[00:47:30] <XXCoder2> LeelooMinai: would simple wood and t-slot channels between em work?
[00:47:40] <XXCoder2> you'd have to level bed once a while but..
[00:47:47] <LeelooMinai> Anyways, my idea is a bit weird I guess. I thought ot using cold rolled steel stripes rised a bit over my main alu table, and with spaces between them - that would effecively form slots. I am not sure though if those cold roled bars could be flat or flattened by me, to have decent flatness
[00:48:11] <jdh> how will you flatten them?
[00:48:30] <ssi> crs is fairly flat
[00:48:40] <ssi> but if you're going to build some structure like that, flatness may go out the window
[00:48:44] <LeelooMinai> well, they may be flat enough I guess - not sure. Otherwise by some kind of abrasive method using router head I will attach at some point anyways
[00:48:55] <LeelooMinai> The thing is, those bars are not too expensive
[00:49:15] <LeelooMinai> And I can get them locally
[00:49:16] <ssi> I think 1/2" or 3/8" thick aluminum plate is probably your best option
[00:49:17] <jdh> I'd go with MDF or MDF over plywood
[00:49:32] <ssi> what's the cost of aluminum plate that size for you?
[00:49:42] <LeelooMinai> ssi: That's much more expensive than those cold rolled flatbars
[00:50:08] -!- dybskiy has quit [Remote host closed the connection]
[00:50:08] <LeelooMinai> o,5 inch plate?
[00:50:18] <XXCoder2> plywood with whatever scrap wood on it to act as surifical wood
[00:50:25] <LeelooMinai> Above $100
[00:50:42] <ssi> ok... and how much is the aluminum t-slot track?
[00:50:56] <LeelooMinai> Ok, but my machine has not a piece of wood on it - I would like to keep it that way kind of:)
[00:51:09] <ssi> then you better not be considering MDF :)
[00:51:16] <ssi> MDF isn't wood; it's WORSE than wood
[00:51:16] <LeelooMinai> ssi: One trace two feet maybe $10
[00:51:20] <LeelooMinai> track*
[00:51:31] <ssi> LeelooMinai: when I bought it here it was more like $20, but ok
[00:51:44] <jdh> http://wilmington.craigslist.org/tls/4500874254.html
[00:51:48] <LeelooMinai> Yes, so even that mdf idea will cost a bit
[00:51:51] <jdh> what do you think that weighs?
[00:51:52] <ssi> yep
[00:52:07] <LeelooMinai> jdh: More than my house? :)
[00:52:08] <ssi> jdh: probably between 2000 and 3000lb
[00:52:21] <ssi> maybe less
[00:52:21] <LeelooMinai> Ok, so no opinion on my "plan"?
[00:52:41] <LeelooMinai> I never had "cold rolled flatbar" in my hand
[00:52:44] <ssi> LeelooMinai: how are you going to mount these CRS bars?
[00:52:45] <jdh> price looks ggod
[00:52:56] <ssi> jdh: that's a very nice lathe
[00:53:02] <jdh> mount them to plywood.
[00:53:14] <LeelooMinai> ssi: With screws - how else?
[00:53:31] <Jymmm> epoxy
[00:53:32] <ssi> LeelooMinai: I'm just trying to get an idea of how you plan to do it
[00:53:50] <ssi> if you started with relatively thick bars, and machined a shoulder on the bottom side
[00:53:58] <XXCoder2> I heard good stuff about carpet double side taoe
[00:54:01] <LeelooMinai> I thought maybe hex scews like I have everywhere, but the thin head kind and just couterboring them.
[00:54:04] <ssi> you can mount it with counterbored cap screws to your undertable
[00:54:12] <ssi> but your undertable isn't big enough!
[00:54:23] <ssi> so you still would need a bigger aluminum plate to mount to the undertable so you can mount the steel to it
[00:54:56] <ssi> also, do you have machining capability to machine a shoulder?

[00:55:10] <LeelooMinai> ssi: I thought the flabars would extend on the Y axis on both sides - shouldn't they be pretty stiff at 0.25 inch?>
[00:55:17] <LeelooMinai> flatbars*
[00:55:21] <ssi> not stiff enough to mount things to
[00:55:32] <Jymmm> LeelooMinai: you have access to a mill?
[00:55:39] <LeelooMinai> Jymmm: No
[00:56:03] <Jymmm> LeelooMinai: Oh, I thought you made your machine for some reason
[00:56:19] <mozmck> LeelooMinai: I don't know what is too expensive: http://www.rockler.com/multi-track-for-jigs-and-custom-fences-multi-track
[00:56:20] <ssi> lol
[00:56:26] <LeelooMinai> Jymmm: What do you mean? I did made it, yes
[00:56:34] <mozmck> Jymmm: all you need is a file for that!
[00:56:38] <Jymmm> LeelooMinai: Then how did you mill it's parts?
[00:56:49] <ssi> hacksaws and files, man
[00:56:58] <LeelooMinai> Jymmm: I MacGyvered it with a table router and carbide bits:)
[00:57:24] <LeelooMinai> Like this: https://www.flickr.com/photos/100017731@N03/10046651986/
[00:57:26] <Jymmm> LeelooMinai: Then remove your existing table and drill and tap it... FREE
[00:57:44] <ssi> existing "table" isn't big enough
[00:57:48] <ssi> that's the problem we're trying to solve
[00:57:58] <LeelooMinai> Jymmm: It's not the full size I want - it's pretty narrow - it was always meant just as a base to attach proper one.
[00:57:59] -!- dybskiy has quit []
[00:58:05] <mozmck> I think the CNCShark that rockler sells uses that multi-track for it's table.
[00:58:09] <Jymmm> putting a larger table on top of a smaller one is a "solution"?!
[00:58:30] <mozmck> 3" x 36" for about $38
[00:58:39] <LeelooMinai> Jymmm: Well, what's wrong with doing that? I designed the whole frame with this table getting up by inch or even more.
[00:58:50] <ssi> LeelooMinai: I honestly think your machine deserves for you to suck it up and buy a proper hunk of aluminum for the table... you went to all the trouble and cost to make it so stiff, don't throw out table rigidity
[00:59:14] <ssi> don't necessarily need tooling plate, but get at least 3/8" 6061 plate
[00:59:39] <LeelooMinai> ssi: What if I use two layers of flatbars. the bottom layer a bit narrower, to form slots?
[00:59:41] <Jymmm> LeelooMinai: That larger table then becomes a fulcrum lever.
[00:59:42] -!- likevinyl has quit [Quit: likevinyl]
[00:59:42] <ssi> OR just drill a couple holes in the table and mount a vise to it and use it like that for now
[00:59:58] -!- sumpfralle has quit [Ping timeout: 244 seconds]
[01:00:04] <ssi> LeelooMinai: you can do that but I think you'll have a hard time getting it acceptably flat
[01:00:11] <LeelooMinai> Jymmm: Well, it would anyways, as I have movable table - I cannot put blocks at the ends obviously.
[01:00:14] <ssi> and you're going to have a very hard time trying to surface a CRS table with a trim router
[01:00:39] <LeelooMinai> Even very slowly?
[01:00:41] <ssi> LeelooMinai: what's the travel on your table? It doesn't look like 500mm from the pictures
[01:00:47] <ssi> yeah even very slowly, it's gonna be tough
[01:00:51] <ssi> much easier to flycut aluminum
[01:00:58] <Jymmm> LeelooMinai: nothign is obvious, I only saw one pic and it wasn't too clear to see details to me.
[01:01:00] <mozmck> the router runs too fast
[01:01:01] <LeelooMinai> Y travel is 270mm
[01:01:17] <ssi> LeelooMinai: bear in mind you don't need a table that's significantly longer than your travel
[01:01:27] <LeelooMinai> But I added 80mm on ends for clamping purposes
[01:01:48] amnesic is now known as amnesic_away
[01:01:50] <LeelooMinai> Well, I think it should be a bit longer than full travel
[01:01:56] -!- mhaberler has quit [Quit: mhaberler]
[01:02:07] <LeelooMinai> So, as I said, there's room for clamps, no?
[01:02:18] <ssi> why not focus on getting your spindle and electronics going, and use what you have for awhile, and see where it's deficient
[01:02:28] <ssi> then you can revisit a different table when you have some experience and money saved up
[01:02:56] <LeelooMinai> ssi: Well, as of now I cannot even clamp anything properly to try, say, millin alu
[01:03:06] <ssi> I think you'd be very well served by getting a reasonably priced vise and putting a couple tapped holes in the short table to mount the vise down
[01:03:08] <Jymmm> LeelooMinai: drill and tap
[01:03:12] <ssi> you're going to want a vise eventually anyway
[01:03:15] <LeelooMinai> I can draw something with a sharpie:)
[01:03:36] <LeelooMinai> Why vise if I would have a nice machinist clamping set?
[01:03:44] <ssi> I have two nice machinists clamping sets
[01:03:45] <Jymmm> LeelooMinai: you hve a 1" plate there, just drill at tap it for a couple of clamps
[01:03:48] <ssi> but I still use my vises all the time
[01:04:00] <ssi> clamps are for holding irregular stuff and fixtures
[01:04:01] <ssi> not everyday work
[01:04:03] <LeelooMinai> Jymmm: It's only 0.5 inch plate
[01:04:12] <Jymmm> LeelooMinai: still enough
[01:04:16] <XXCoder2> ssi really because I constantly use clamps at work
[01:04:25] <LeelooMinai> Hmm... somehow I guess such vises are probably not cheap
[01:04:34] <ssi> they're not cheap, but they don't have to be terribly expensive either
[01:04:38] <ssi> you get what you pay for of course
[01:05:00] <LeelooMinai> Also, vise has smallish span in comparison to full table + clamps
[01:05:03] <XXCoder2> saw one site where someone used hand clamps and changed em into router cnc bed clamps
[01:05:14] <ssi> LeelooMinai: so let me ask you this... do you know what you intend to make on this machine?
[01:05:38] <LeelooMinai> It's not really a machine to do one thing as I said.
[01:05:44] <ssi> understandable...
[01:05:49] <Jymmm> LeelooMinai: do you have a piece of MDF scrap 24" long?
[01:05:49] <ssi> but you need to have some goals in mind
[01:05:57] <ssi> if a vise is too small
[01:06:01] <ssi> what's it too small to hold?
[01:06:06] <ssi> I have a 4" vise that does 90% of my work
[01:06:14] <ssi> and that's on a 9x42" bridgeport
[01:06:25] <ssi> occasionally I bust out a 6" vise
[01:06:28] <LeelooMinai> Well, one day my mom may need something done that will require a biggish piece of wood for example - how will I use vise for that?
[01:06:29] <ssi> which btw weighs about 80lb
[01:06:59] <mozmck> note also that a standard bridgeport has a Y travel of only about 9" or so too
[01:07:01] <ssi> well for starters, you can put jaws on the outside of a vise and they'll hold 18" or so
[01:07:19] <ssi> maybe not 18"
[01:07:22] <ssi> but it's bigger than you think
[01:07:34] <LeelooMinai> Hmm..
[01:07:59] <ssi> workholding is one of the most significant challenges in machining btw
[01:08:10] <XXCoder2> ssi: someone here called it dark art
[01:08:11] <ssi> there's a million different ways to fixture things
[01:08:16] <ssi> XXCoder2: that's pretty apt
[01:08:25] <LeelooMinai> I guess a could use a vise - when I was designing the frame I made it a bit high on the z-axis on purpose
[01:08:29] <ssi> LeelooMinai: improper workholding can hurt you
[01:08:36] <Jymmm> LeelooMinai: graba book, brick whatever, place a piece of LDF that is longer on each end by 2" on top of the brick, Place your foot on the mdf, then grab each 2" over hang and flex the mdf upward. If you keep doing that over time clamping down aluminum bilet to machine, it''s gonna crack at the worse possible time.
[01:08:46] <Jymmm> MDF*
[01:08:51] <XXCoder2> heh my cnc router design as it stands has only bit less than 3 inches clearance lol
[01:08:58] <LeelooMinai> ssi: I know that - I may have no experience, but when making the frame I found out those basic pretty quickly:)
[01:09:02] <ssi> XXCoder2: well routers are a different design
[01:09:23] <ssi> LeelooMinai: I'm sure you did... I've run aluminum across a router before, and it can be scary
[01:09:39] <ssi> XXCoder2: my plasma cutter only has 2" clearance, but I'd never try to mount a vise to it :P
[01:09:42] <Jymmm> LeelooMinai: The clamp kit you want to use exerts a LOT of force.
[01:09:45] <ssi> this little machine she's built is a mill
[01:10:07] <LeelooMinai> ssi: That's that picture with me with the face mask and ear muffs - I was dressed like a medieval knight when doing this
[01:10:20] <ssi> LeelooMinai: very wise :) I'm not that smart
[01:10:24] <ssi> or rather, I am that reckless
[01:10:25] <ssi> heheh
[01:11:11] <LeelooMinai> First I was thinking if I could use the drill press for that somehow, but now after reading a bit I know that would not work

[01:11:47] <LeelooMinai> I guess I should research now the proces of those vise
[01:11:56] <LeelooMinai> prices*
[01:12:13] <ssi> so, there's Kurt, and they're expensive
[01:12:16] <ssi> $1000 or so
[01:12:22] <LeelooMinai> ...
[01:12:22] <ssi> I bought my 4" double kurt on ebay for $250
[01:12:33] <LeelooMinai> Did you miss the part when I was talking $100 or less? :)
[01:12:38] <ssi> i'm getting there
[01:12:56] <ssi> glacern machine tool makes nice vises, but they've come up in price it looks like
[01:13:07] <ssi> $400 now for a 4" :/
[01:13:18] <ssi> shars makes some cheap chinese vises that are ok
[01:13:23] <ssi> they're not great, but they'll probably do for starters
[01:13:46] <ssi> http://www.shars.com/products/view/62/5x5x112quot_Lock_Down_Precision_Milling_Machine_Vise
[01:13:51] <ssi> that might be too big for your machine
[01:14:03] -!- sudobangbang has quit [Ping timeout: 240 seconds]
[01:14:20] <LeelooMinai> Ok, so the vise would cost the same as a table it seems
[01:14:31] <ssi> for something usable, yes
[01:14:44] <LeelooMinai> It looks nice, that wise
[01:15:29] <ssi> you could realy cheap out in the short term and get a drill press vise
[01:15:30] <ssi> http://www.shars.com/products/view/331/5quot_Horizontal_and_Vertical_Drilling_Press_Vise
[01:15:33] <ssi> somethinhg like that
[01:15:49] <ssi> but don't hold out any great hope of it being repeatable or standing up to at on of abuse
[01:16:10] <LeelooMinai> Ok, that one in comparison to the other looks like T-34 vs some modern tank
[01:16:31] <ssi> lol :D

[01:16:57] <ssi> so with machining, rigidity is your friend, as you obviously know looking at your machine
[01:17:05] <ssi> and rigidity comes with mass, which you also obviously know :)
[01:17:18] <LeelooMinai> Yes, those vises would probably even stiffen the table I have
[01:17:23] <ssi> unfortunately, mass means $$$
[01:18:13] <zeeshan|3> just wanted to through this out there
[01:18:16] <LeelooMinai> Yes, otherwise I would have nice Chinese heavy tools bought by aliexpress
[01:18:16] <zeeshan|3> fak glacern vises!
[01:18:20] <zeeshan|3> too expensive :P
[01:18:54] <ssi> zeeshan|3: they used to be a pretty good value
[01:18:58] <ssi> I recall them having a nice vise for like $250
[01:19:05] <LeelooMinai> Is that one of those "cult" brands that is 20% better than others and costs 5c more?
[01:19:06] <ssi> I was gonna buy one for my little mill
[01:19:09] <ssi> but I guess I missed my shot
[01:19:14] <zeeshan|3> theres so many of those vises on sale
[01:19:15] <LeelooMinai> 5x*
[01:19:16] <zeeshan|3> on kijiji
[01:19:17] <ssi> LeelooMinai: no, that'd be kurt :P
[01:19:20] <zeeshan|3> no oneed to buy that stuff online
[01:19:32] <ssi> kurt vises are very nice, but they're VERY EXPENSIVE

[01:20:09] <zeeshan|3> XXCoder2: whats so funny
[01:20:11] <ssi> XXCoder2: for the same money you can buy the self-adjusting bessey toggles :P
[01:20:13] <zeeshan|3> toggle clamps are awesome :D
[01:20:15] <LeelooMinai> I just got a quote from a local guy for aluminum extrusions for my table - $146 with delivery ot so
[01:20:31] <zeeshan|3> what kind of extrusion
[01:20:33] <XXCoder2> zee yeah but just wondering if its even usable with certain setups
[01:20:53] <zeeshan|3> XXCoder2: i think theyre meant for fixture type of applications
[01:20:57] <zeeshan|3> where you have thje same of something
[01:21:03] <zeeshan|3> at least thats where ive used em :P
[01:21:19] <ssi> yeah and typically woodworking applications
[01:21:27] <LeelooMinai> zeeshan|3: http://www.kijiji.ca/v-hobbies-craft/mississauga-peel-region/aluminum-t-slot-rail-80x20-for-custom-assemblies-new/559243073?enableSearchNavigationFlag=true
[01:21:27] <ssi> I don't think I'd trust toggle clamps for metal milling
[01:21:56] <LeelooMinai> Hmm, probably will not pay $150 for those
[01:22:04] <zeeshan|3> 9$ a foot seems pretty good
[01:22:17] <zeeshan|3> 8020 is expensive
[01:22:42] <Tom_itx> ssi, they work ok on flat plate etc
[01:22:45] <LeelooMinai> Yes, I guess... But ssi now confused me with that vise idea;)
[01:23:01] <ssi> LeelooMinai: that's what I'm here for ;)
[01:23:03] <zeeshan|3> LeelooMinai: yo uneed to figure out what youre using the machine for
[01:23:08] <ssi> zeeshan|3++
[01:23:20] <ssi> you probably will end up wanting a vise eventually anyway
[01:23:24] <zeeshan|3> theres a reason why most machines hjave t-slot tables
[01:23:29] <ssi> and getting a vise will get you running quicker
[01:23:31] <zeeshan|3> because it allows you to mount vises too
[01:23:36] <zeeshan|3> and do all sorts of fancy stuff
[01:24:01] <mozmck> a simple drill press vise would get you running quickly for very little money.
[01:24:13] <zeeshan|3> drill press vises cheap ones flex
[01:24:14] <zeeshan|3> =/
[01:24:18] <jdh> so, that beautiful, old, real iron lathe is half as much as a chinese router
[01:24:19] <LeelooMinai> For nerdy stuff mostly - expermients, alu millin to make cases for ee projects, maybe some aluminum "robotic" parts and things like that, also maybe pcb routing experimients, cutting acrylic with laser, cutting pcb stencils with laser - you know, regular stuff
[01:24:25] <Tom_itx> a threaded grid pattern on a plate is quite useful too
[01:24:26] <ssi> zeeshan|3: not as much as mdf! :D
[01:24:29] <zeeshan|3> haha
[01:24:32] <zeeshan|3> bloody mdf
[01:24:41] <ssi> jdh: that beautiful lathe may well be worn the hell out
[01:25:00] <zeeshan|3> LeelooMinai: so it sounds like you'll be machining both sheet
[01:25:03] <zeeshan|3> and small components
[01:25:04] <mozmck> ssi: exactly, this is a very small mill/router to start with.
[01:25:09] <zeeshan|3> you want t-slot table for sheet parts
[01:25:17] <zeeshan|3> and vise for smaller components
[01:25:30] <ssi> zeeshan|3++ :)
[01:25:35] <jdh> you want t-slot to hold the mdf down
[01:25:46] <zeeshan|3> where is this mdf coming from
[01:25:48] <zeeshan|3> damn mdf
[01:25:48] <ssi> small stuff is going to be nearly impossible to fixture with machinists clamps
[01:25:48] <mozmck> slap a drill press vise on to play with it, while you are looking for better options for a t-slot table.
[01:26:03] <jdh> small stuff gets screwed down into the mdf
[01:26:20] <zeeshan|3> mdf is bad
[01:26:23] <zeeshan|3> plywood!
[01:26:26] -!- likevinyl [likevinyl!~likevinyl@unaffiliated/likevinyl] has joined #linuxcnc
[01:26:45] <zeeshan|3> mdf is like asbestos
[01:26:51] <zeeshan|3> lung cancer!
[01:26:53] <LeelooMinai> Are there materials, non-metalic, that would be between mdf and alu and not expensive?
[01:27:18] <ssi> plywood
[01:27:23] <ssi> get mdf out of your head
[01:27:25] <jdh> mdf is better than plywood
[01:27:28] <zeeshan|3> plywood is cheaper than mdf
[01:27:31] <zeeshan|3> jdh no its not
[01:27:35] <zeeshan|3> WTF!
[01:27:41] <ssi> mdf is certainly not better than plywood
[01:27:52] <jdh> I disagree (for this)
[01:27:54] <zeeshan|3> lets make our house floor boards out of mdf
[01:27:57] <zeeshan|3> not plywood
[01:27:57] <ssi> it has no strength whatsoever
[01:28:00] <ssi> it won't hold screws
[01:28:05] <LeelooMinai> I see mdf is a hot topic for debates here:)
[01:28:08] <ssi> it gets ruined if the humidity exceeds 80%
[01:28:11] <ssi> it gives you cancer
[01:28:15] <zeeshan|3> LeelooMinai: because its a carcogenic
[01:28:18] <zeeshan|3> and peole still use it
[01:28:26] <zeeshan|3> its note even cheaper than plywood
[01:28:29] <ssi> it's far more flexible than plywood
[01:28:31] <LeelooMinai> Hmm...
[01:28:39] <ssi> it has compressive strength and that's it
[01:28:43] <zeeshan|3> it's only good purpose is for sound boxes for speakers
[01:28:46] <ssi> it's good for making ikea furniture and countertops
[01:28:56] <ssi> it's not even GOOD for speakers
[01:29:01] <jdh> it's good for making disposable router tops
[01:29:07] <ssi> I make my speakers from 13ply baltic birch ply
[01:29:08] <LeelooMinai> Well, I kind of ruled it out anyways
[01:29:14] <zeeshan|3> ssi: haha
[01:29:20] <zeeshan|3> sounds expensive
[01:29:35] <ssi> it can be
[01:29:38] <ssi> $50-60/sheet

[01:29:49] <ssi> $90 for domestic
[01:29:49] <zeeshan|3> 4'x8'?
[01:29:51] <ssi> ya
[01:29:56] <zeeshan|3> that is expensive
[01:30:05] <ssi> yeah
[01:30:15] <zeeshan|3> jdh they're all doing it wrong
[01:30:17] <zeeshan|3> !
[01:30:26] <LeelooMinai> also, wood can be eaten by termites
[01:30:33] <ssi> HAH
[01:30:43] <ssi> LeelooMinai: the moisture is a much more real issue than termites :)
[01:30:49] <jdh> If you can't make it out of decent aluminum. I'd make it out of plywood topped with mdf
[01:31:15] <jdh> I have MDF on mine in my garage for years. It's fine.
[01:31:28] <ssi> if it was a big gantry router designed for cutting shapes out of plywood I would agree
[01:31:32] <ssi> but that's not what this machine is
[01:31:42] <jdh> it isn't anything without a table
[01:31:56] <jdh> and it's not like it has to be permanent, or perfect the first iteration.
[01:32:12] <zeeshan|3> im gonna use mdf on my mill
[01:32:35] <jdh> certainly not for a traditional mill
[01:32:38] <zeeshan|3> jdh
[01:32:44] <LeelooMinai> I read about something called derlin - but I guess that would not be cheap
[01:32:44] <zeeshan|3> does mdf come in 4" round?
[01:32:57] <jdh> delrin is quite pricy. and soft
[01:32:58] <zeeshan|3> i want to make a special cnc dildo for you
[01:33:01] <zeeshan|3> mr mdf lover
[01:33:06] <ssi> LeelooMinai: delrin isn't what you want
[01:33:08] <zeeshan|3> =D
[01:33:22] <jdh> delrin is my almost-favorite material
[01:33:22] <zeeshan|3> whats wrong with delrin
[01:33:26] <LeelooMinai> I also saw people using granite and some kind of resin to make frames - not sure if a table could be made like that
[01:33:28] <ssi> delrin is awesome
[01:33:32] <ssi> but it's not rigid at all
[01:33:32] <zeeshan|3> i luf delrin
[01:33:51] <ssi> LeelooMinai: granite isn't going to be good for putting tslots or holes in
[01:34:01] <ssi> it's good for flat surfaces, and good for machine bases
[01:34:10] <jdh> pour teh granite then screw down teh t-slots to it.
[01:34:11] <zeeshan|3> it's also good for breaking on people's head
[01:34:12] <LeelooMinai> ssi: I would assume they would have to be embedded during the forming of it
[01:34:13] <ssi> and it CAN be tslotted, i've seen granite topped table saws
[01:34:17] <jdh> then put the MDF on top of teh T-slots
[01:34:29] <ssi> LeelooMinai: jdh REALLY wants you to use MDF :)
[01:34:51] <jdh> it doesn't matter what I want. It *will* have MDF on it at some point.
[01:34:55] <ssi> btw have we ever had this dramatic of an argument over how to design someone else's machine before?
[01:35:05] <zeeshan|3> no
[01:35:07] <zeeshan|3> im trollin
[01:35:09] <ssi> :)
[01:35:11] <jdh> there's no drama, you are just snobs with no budget constraints
[01:35:18] <LeelooMinai> Well, at least it's obvious that everyone has own idea about those things:)

[01:35:50] <jdh> I am cheap.
[01:35:55] <jdh> hence the MDF.
[01:35:58] <LeelooMinai> I was waiting for someone saying that the only good tables are made from titnoum or something like that
[01:36:07] <LeelooMinai> titanium*
[01:36:08] <jdh> cast iron
[01:36:11] <Tom_itx> yup
[01:36:13] <zeeshan|3> cast iron win
[01:36:14] <zeeshan|3> !
[01:36:15] <Tom_itx> good ole iron
[01:36:20] <Jymmm> diamond
[01:36:25] <Tom_itx> pfft
[01:36:32] <zeeshan|3> diamond has no dampening
[01:36:38] <zeeshan|3> or little dampening
[01:36:38] <zeeshan|3> ;p
[01:36:48] <LeelooMinai> Drilling holes in diamond could be problematic
[01:37:01] <ssi> cast iron absolutely is the right answer
[01:37:04] <ssi> but not for your machine :)
[01:37:13] <jdh> just grow the diamond around the holes
[01:37:19] <LeelooMinai> Well, my table moves
[01:37:23] <LeelooMinai> Cannot be too huge
[01:37:24] <ssi> so does mine!
[01:37:25] <jdh> what are your table dims?
[01:37:29] <Jymmm> jdh: not a bad idea acutally
[01:37:37] <LeelooMinai> The table should be 500x520 or so
[01:37:39] <LeelooMinai> mm
[01:37:43] <LeelooMinai> 530*
[01:37:45] <ssi> and I dunno what the table on a bridgie weighs, but I did have it off once and it's a lot
[01:37:48] <ssi> more than I can lift on my own
[01:37:56] <zeeshan|3> abot 250lb
[01:37:59] <zeeshan|3> you weakling
[01:38:00] <ssi> sounds about right
[01:38:03] <zeeshan|3> jk
[01:38:09] <zeeshan|3> it weighs twice what i weigh
[01:38:15] <ssi> lol you weigh 125?
[01:38:19] <zeeshan|3> close
[01:38:20] <zeeshan|3> 140
[01:38:24] <Jymmm> wet
[01:38:25] <ssi> speaking of weaklings :D
[01:38:28] <zeeshan|3> haha
[01:38:35] <jdh> same as my left leg.
[01:38:38] <ssi> jdh: :)
[01:38:40] <zeeshan|3> hahah
[01:38:57] <zeeshan|3> people like me is the reason breaker bars were invented
[01:39:03] <zeeshan|3> *why
[01:39:13] <ssi> still gotta have mass to apply to the end of the breaker bar!
[01:39:15] <LeelooMinai> What does it matter if he is skinny if his steppers have high torque
[01:39:17] <zeeshan|3> haha
[01:39:21] <ssi> LeelooMinai: :D
[01:39:36] <ssi> LeelooMinai: it's all about rigidity, remember?
[01:40:08] <zeeshan|3> to be honest, the only bolt i've ever had issues loosening was the flywheel single nut that is torqued to 320ft-lb
[01:40:18] <zeeshan|3> i had to use a 4 foot rod on my breaker bar
[01:40:28] <Jymmm> ssi: Sorry dude, blue pills don't work on MDF, m'kay!
[01:40:33] <ssi> ugh I had to take upper balljoints out of a dodge pickup front end once, and they're threaded in
[01:40:37] <ssi> like 1600lb/ft
[01:40:43] <zeeshan|3> lol
[01:40:46] <ssi> took a ten foot bar and two dudes
[01:40:46] <XXCoder2> one thing I'm not buying is mdf. its not free.
[01:40:47] <ssi> sucked
[01:40:55] <XXCoder2> I can get pretty lot wood for free but not that
[01:41:02] <jdh> XX: you will
[01:41:15] <XXCoder2> nope. nonfree wood? no buy lol
[01:41:21] <ssi> XXCoder2: it's not nearly cheap enough for what it is
[01:41:38] <XXCoder2> flying mdf board?
[01:41:58] <zeeshan|3> you cant even use mdf
[01:42:00] <zeeshan|3> for a camp fire :[
[01:42:08] <ssi> nor would you want to
[01:42:18] <ssi> ugh breathing burning mdf vapor sounds miserable
[01:42:53] <XXCoder2> well I just finally opened my trim router
[01:43:03] <zeeshan|3> if i only had 25 bux to spend ona table
[01:43:04] <XXCoder2> its bit smaller than I expected so I am revising design
[01:43:13] <zeeshan|3> i'd just go grab some spruce plywood 3/4" thick
[01:43:15] <zeeshan|3> and call it a day
[01:43:22] <jdh> that would work
[01:43:29] <zeeshan|3> drill holes all over it
[01:43:29] <jdh> but, get some MDF to put on top of it.
[01:43:35] <zeeshan|3> lol jdh
[01:43:35] <zeeshan|3> die
[01:43:50] <jdh> you want to cut in to your nice plywood?
[01:43:58] <zeeshan|3> its only 25 bux
[01:44:00] <XXCoder2> I can get expensive plywood for free
[01:44:02] <zeeshan|3> once i cut into it
[01:44:08] <zeeshan|3> i'll turn it into a shelf inthe shop
[01:44:09] <zeeshan|3> :D
[01:44:22] <XXCoder2> thing is it wont be larger than foot across unless I get failed cut ones meaning it will be damaged and still bit small
[01:45:20] <ssi> I think I'm gonna be builiding a pick and place machine here soon with a friend
[01:46:01] <jdh> I'm paying someone to take out a pick and place machine
[01:46:11] <ssi> eh?
[01:46:12] <jdh> and replace it with a 6-axis ABB
[01:46:14] <zeeshan|3> jdh all this time you spend on irc
[01:46:18] <zeeshan|3> you'd be done your lathe
[01:46:20] <ssi> bring me the machine they take out :)
[01:46:40] <ssi> zeeshan|3: yeah I could have been rewiring the plasma table tonight :P
[01:46:41] <jdh> it is an odd little system for specific parts.
[01:46:55] <zeeshan|3> do it!
[01:47:02] <zeeshan|3> irc is for people done with their projects
[01:47:04] <zeeshan|3> :)
[01:47:05] <ssi> heh
[01:47:10] <ssi> or stuck on their projects
[01:47:12] <zeeshan|3> no one would be here
[01:47:13] <jdh> I can not seem to solve teh X problem
[01:47:15] <zeeshan|3> if that was the case lol
[01:47:20] <zeeshan|3> jdh do it ghetto like me
[01:47:21] <zeeshan|3> it works
[01:47:23] <ssi> I still don't have the parts I need to decouple the ohmic line :/
[01:47:32] <ssi> pcw said use optos, but I gotta figure out which optos and order them
[01:47:37] <jdh> though it is currently c-clamped in place and would 'work' if I drilled and tapped 2 holes
[01:47:39] <ssi> was thinking maybe a PAIR of relays would work
[01:47:42] <ssi> decouple the line and the ground
[01:47:46] <ssi> or a dpst relay
[01:47:53] <zeeshan|3> jdh ball screw outside of table?
[01:47:54] <ssi> but I don't have any relays, or any field voltage with which to run them
[01:47:56] <zeeshan|3> (towards chuck?)
[01:48:03] <jdh> yeah.
[01:48:05] <jdh> suckage
[01:48:08] <zeeshan|3> works
[01:48:11] <zeeshan|3> just put a cover on it
[01:48:22] <jdh> won't be able to work near the chuck
[01:48:28] <zeeshan|3> yep

[02:10:16] <LeelooMinai> I am calculating deflections of the table in extreme positions. What would be some resonable maximum force to assume for milling aluminum?
[02:10:35] <XXCoder2> 6000N
[02:10:37] <XXCoder2> jk
[02:10:44] <LeelooMinai> I mean from the top
[02:11:05] <LeelooMinai> when the endmill goes down
[02:11:15] <XXCoder2> joking (in case you didnt know what jk is)
[02:11:28] <LeelooMinai> Amd what deflection could one tolerate?
[02:14:01] -!- MrHindsight has quit [Quit: Leaving]
[02:14:28] <zeeshan|3> LeelooMinai: how are you calculating deflections?
[02:14:36] <zeeshan|3> how are you treating the table
[02:14:44] <LeelooMinai> Just with this: http://www.botlanta.org/converters/dale-calc/bending.html
[02:15:08] <zeeshan|3> so as a cantilevered beam
[02:15:15] <zeeshan|3> i dont think thats a reasonable model
[02:15:17] <LeelooMinai> I assume force is applied at the edge, and the pivot will be close to the edge of the current table
[02:15:22] <zeeshan|3> you want to treat it like a simply supported beam
[02:15:25] <LeelooMinai> So, the "trampoline" case
[02:15:46] <LeelooMinai> I have no idea what forces are involved though when milling
[02:15:53] <zeeshan|3> well theres 3 main ones
[02:16:04] <zeeshan|3> tangential, radial, and axial forces
[02:16:17] <zeeshan|3> depending on the orientation of the tool
[02:16:20] <zeeshan|3> and it's movement
[02:16:26] <zeeshan|3> one of them is typicalled called a 'feed force'
[02:16:27] <LeelooMinai> For now I look at downwards force
[02:17:14] <LeelooMinai> Or maybe upwards I guess if the millend can cause it (?)
[02:17:47] <zeeshan|3> in my bok they use
[02:17:51] <LeelooMinai> So maybe that's the "axial" one
[02:18:02] <zeeshan|3> feed force (in the case drilling, its the force pointing downwards)
[02:18:34] <zeeshan|3> found the same formula online
[02:18:36] <LeelooMinai> Any ideas what that is in some very wide approximation?

[02:19:02] <zeeshan|3> if you tell me the largest end mill you'll be running
[02:19:05] <zeeshan|3> it'll help :P
[02:19:13] <LeelooMinai> Diameter?
[02:19:15] <zeeshan|3> yea
[02:19:43] <LeelooMinai> Well, I will for now pobably use some small handheld router with 1/4 endmills - I think
[02:20:06] <LeelooMinai> NOt sure if the bit end can exceed 1/4 then - probably not (?)
[02:20:36] <XXCoder2> zeeshan|3: think that router assembly would stand up to cutting?
[02:20:45] <zeeshan|3> XXCoder2: which one
[02:20:53] <XXCoder2> https://dl.dropboxusercontent.com/u/53432577/cncplm.png
[02:20:57] <zeeshan|3> LeelooMinai: assume you're cutting aluminum..
[02:21:04] <LeelooMinai> Yes
[02:21:14] <LeelooMinai> 6061-T6
[02:21:29] <zeeshan|3> so typically the surface feet per minute rating is 300
[02:21:36] <zeeshan|3> but on your machine you probably dont wanna go that fast
[02:21:39] <zeeshan|3> i'd do 100..
[02:22:10] <XXCoder2> zee everything brown is a type of wood. in my design plywood will be used to use parts for holding router
[02:22:18] <zeeshan|3> and the tool feed recommended based on the charts on the low end is 0.005 inches/tooth , lets assume 2 flute end mill (2 teeth)
[02:22:25] <zeeshan|3> so roughly 0.002 inches/rev
[02:23:20] <zeeshan|3> i need the power density of aluminum

[02:25:41] <zeeshan|3> rather than manually calculating
[02:26:03] <zeeshan|3> cutting speed iis 100sfm, depth of hole is irrelevant, thats to calculate time of cut inthat calculator

[02:27:13] <zeeshan|3> it should be close to 50lb
[02:27:19] <zeeshan|3> LeelooMinai: do you have a bathroom scale?
[02:27:44] <LeelooMinai> Yes
[02:27:55] <zeeshan|3> take a piece of wood and put a piece of aluminum on it
[02:27:58] <LeelooMinai> For alu it seems to be 15 only
[02:27:59] <zeeshan|3> and drill a 1/4" hole
[02:28:02] <zeeshan|3> and read the scale
[02:28:09] <zeeshan|3> you'll get a practical idea of what the force is like
[02:28:20] <zeeshan|3> (the wood piece is so you dont drill into your scale!)
[02:28:44] <zeeshan|3> yea it says 17lb for me
[02:28:45] <LeelooMinai> Right, I need just a rough idea though - my mom is asleep so I better not drill now:)
[02:28:51] <zeeshan|3> seems kinda small, but i msotly cut in steel
[02:29:16] <zeeshan|3> you have 2 rails on each side of your table right?
[02:29:31] <LeelooMinai> Yes
[02:29:42] <zeeshan|3> http://www.geom.uiuc.edu/education/calc-init/static-beam/img/simple.gif
[02:29:47] <zeeshan|3> thats the type of model you should use
[02:29:51] <LeelooMinai> Hmm, with 0.188 steel flatbars it's 18 mil deflection - that's not very good
[02:30:06] <zeeshan|3> for worst case scenario, the forc would be right in the middle
[02:30:27] <LeelooMinai> zeeshan|3: I was computing something else - using flatbars perpendicular to the current table
[02:30:37] <LeelooMinai> they would extend about 6 inches
[02:30:46] <zeeshan|3> ah
[02:31:10] <LeelooMinai> Hmm, I will try with 0.5 inch alu flatbars
[02:31:28] <zeeshan|3> if you're trying to design for stiffness
[02:31:35] <zeeshan|3> a solid piece of metal is a waste of material
[02:31:36] <LeelooMinai> 2 mil - better, but that's to high, right?
[02:31:53] <XXCoder2> LeelooMinai: http://www.aliexpress.com/item/Aluminum-Profile-Extrusion-30150B/1036596308.html
[02:32:09] <XXCoder2> 18 bucks per meter. too damn bad shipping is all kinds of insane
[02:32:10] <zeeshan|3> 2 mil is very little deflection for your machine
[02:32:13] <LeelooMinai> Yes, I considered those - it would cost $140 or so
[02:32:26] <LeelooMinai> From local guy
[02:32:31] <zeeshan|3> http://engineering-references.sbainvent.com/strength_of_materials/pictures/deflection_equations_simply_supported_beam.jpg
[02:32:44] <zeeshan|3> vmax = -pl^3/48EI
[02:32:55] <LeelooMinai> Yes, I just use this: http://www.botlanta.org/converters/dale-calc/bending.html
[02:32:57] <zeeshan|3> vmax like you know is the deflection, p is your force, l is the length
[02:33:12] <zeeshan|3> im trying to explain something using the formula
[02:33:13] <zeeshan|3> !!!
[02:33:28] <LeelooMinai> That's using this formula
[02:33:30] <zeeshan|3> e is your modulus of elasticity (ie how elastic the material is)
[02:33:37] <zeeshan|3> they're all similar
[02:33:44] <zeeshan|3> the point im trying to make is I is on the bottom
[02:33:46] <zeeshan|3> it's your moment of inertia
[02:34:04] <zeeshan|3> moment of inertia for example a square tube 1/8" thick 1x1"
[02:34:05] <LeelooMinai> I know what you mean
[02:34:13] <zeeshan|3> will outperform a 3/8" flat bar
[02:34:17] <zeeshan|3> (very generlized comparison)
[02:34:18] <LeelooMinai> That's why with the same mass sqwuare tube is better than solid
[02:34:27] <zeeshan|3> yes
[02:34:32] <zeeshan|3> so why not look at square sections?
[02:34:35] <zeeshan|3> theyre very cheaap
[02:34:42] <LeelooMinai> I am just trying to balance cost of all of this
[02:34:55] <zeeshan|3> i bet 1" x1" square bar
[02:34:59] <LeelooMinai> Because square section will not give me t-slots
[02:35:01] <zeeshan|3> (tube i mean)
[02:35:03] <zeeshan|3> .125 thick
[02:35:13] <zeeshan|3> technically they can
[02:35:16] <LeelooMinai> Unless it had very thick walls
[02:35:18] <zeeshan|3> if you mill em out :p
[02:35:23] <LeelooMinai> And I could cut into them
[02:35:43] <LeelooMinai> But that would weaken them too
[02:36:02] <zeeshan|3> yea :p
[02:36:20] <zeeshan|3> thiis where fea analysis is useful
[02:36:25] <zeeshan|3> try different combinations and see the effects
[02:36:36] <LeelooMinai> Maybe I should just steel some railroad tracks
[02:36:46] <zeeshan|3> if you know a cheap source for those let me know!
[02:36:50] <zeeshan|3> i've been looking for some
[02:37:15] <zeeshan|3> they 're a good hunk of metal

[02:44:28] <zeeshan|3> or just wood
[02:44:56] <XXCoder2> yeah and im not sure. if I make bearing blocks take more space the board would have to be longer to reach surface

[03:06:44] <zeeshan|3> cause then you dont need an external toroidal supply
[03:13:53] <XXCoder2> probably>

[04:37:37] <PetefromTn_> night, morning, what have you..LOL
[04:38:09] <PetefromTn_> I am about to throw my net connected blu ray player out the freakin' window...
[04:38:48] <PetefromTn_> LG POS...

[04:41:26] <ssi> :)
[04:41:35] <ssi> I'm no dutchie, so I suppose you're right
[04:42:07] <PetefromTn_> Freakin' thing NEVER connects even sometimes after I reset the wireless router with my laptop...ANNOYING!!
[04:42:36] <PetefromTn_> It is the only damn thing in the whole house full of interconnected wireless crap that does not...
[04:43:03] <PetefromTn_> This is the second one we got and tried too. Took the first one back because of the same issue.
[04:43:19] <ssi> I've never owned a standalone bluray player
[04:43:23] <ssi> always just used the ps3 for that
[04:43:29] <PetefromTn_> we do that too...
[04:43:57] <PetefromTn_> use this thing to watch netflix and youtube stuff aside from watching movies on blu ray.
[04:44:01] <ssi> gotcha
[04:44:03] <ssi> I use appletv for that
[04:44:07] <ssi> but ps3 can do it too
[04:44:18] <PetefromTn_> yeah I know..
[04:44:20] <ssi> everything does netflix these days :P
[04:44:26] <ssi> hell most new tvs even do it
[04:44:28] <ssi> nuts
[04:44:30] <PetefromTn_> everything but this POS.
[04:44:33] <ssi> ehehe
[04:44:51] <PetefromTn_> my TV does it as well..but we are loathe to run the damn cable again under the house.
[04:45:21] <ssi> yea
[04:45:28] <PetefromTn_> My wife decided she wanted to rearrange the room again and now the big flatscreen is on the other side..
[04:45:53] <ssi> lol comcast is advertising 505mbit internet here now
[04:45:55] <ssi> $399/mo
[04:45:56] <PetefromTn_> I guess I am gonna have to break down and crawl under there. Was hoping this POS would just work wirelessly but whatyagonnado....
[04:46:08] <PetefromTn_> GASP!!
[04:46:15] <ssi> sorry, $399.95
[04:46:18] <ssi> :P
[04:46:23] <ssi> I wonder if it still has a 300GB/mo cap
[04:46:28] <PetefromTn_> STILL GASPING>..
[04:46:30] <ssi> I have the 105mbit now, and it has the same 300GB/mo cap
[04:46:33] <ssi> ridiculous
[04:46:40] <ssi> oh man it gets better
[04:46:48] <ssi> $400/mo and you have to sign a THREE YEAR CONTRACT
[04:47:21] <PetefromTn_> We have Charter high speed and it actually is perfect... We do not have the highest speed tier just the second highest.
[04:47:48] <PetefromTn_> For $400 a month I better get a geisha and a masseuse with it...
[04:47:53] <ssi> srsly
[04:48:27] <PetefromTn_> must be all those rich folks in Hotlanta driving the prices up or something LOL..
[04:50:03] <PetefromTn_> Perhaps tomorrow I will tunnel under and hookup the cable finally. I am so over this POS...
[04:50:15] <ssi> whoa chattanooga has municipal gigabit fiber service for $70/mo
[04:50:19] <ssi> provided by the electric company
[04:50:22] <ssi> that's pretty awesome
[04:50:26] <ssi> almost awesome enough to move there
[04:50:31] <ssi> it'd add 70 miles to my commute :P
[04:50:39] <PetefromTn_> hell fly to work man...
[04:50:54] <ssi> you know, I always wanted to build a helicycle and see if they'd let me land it on the parking deck
[04:50:59] <PetefromTn_> then you can move here, buy my house and my CNC and be happy LO...
[04:51:05] <ssi> hahahah
[04:51:07] <Jymmm> 1Gbps up and down
[04:51:46] <PetefromTn_> My wife is off all next week and we are gonna finish our damn kitchen finally or at least that is the plan.
[04:52:28] <ssi> Jymmm: yaaaa
[04:52:30] <ssi> " In Chattanooga TN, the public utility provides 1 gigabit/sec download & 1 gigabit/sec upload speeds for $70 a month, which is $20 a month less than I'm paying my broadband monopoly (Comcast) for 1/20th the download speed and 1/100th the upload speed as Chattanooga's municipal network."
[04:52:43] <ssi> fiber to the home is awesome
[04:54:11] <Jymmm> Not available here (yet)
[04:54:34] <ssi> I was actually surprised at how much the internet available in the bay area is NOT great
[04:55:04] <Jymmm> It depends on where you are, lots of OLD copper
[04:55:15] <PetefromTn_> I think mine is like 30 or 40 MBPS or something like that.
[04:55:36] <ssi> mine clocks speedtest at 122
[04:55:57] <Jymmm> you guys must be on cable
[04:56:04] <ssi> yep
[04:56:17] <PetefromTn_> they are always talking about how fast they are and how great a value it is...perhaps they are full of shite..
[04:56:21] <ssi> cable and fiber are the only options these days :P
[04:56:24] <PetefromTn_> yeah cable
[04:56:25] <ssi> dsl got left behind long ago
[04:56:41] <Jymmm> Well, ADSL did, there is VDSL now.
[04:56:49] <PetefromTn_> I don't even think I know anyone with DSL anymore.
[04:56:58] <Jymmm> I have VDSL
[04:57:06] <ssi> what sort of speeds do you see
[04:57:08] <Jymmm> I used to have ADSL long ago
[04:57:14] <PetefromTn_> venereal disease speedy light..?
[04:57:28] <Jymmm> I have 18/1 unshared, unlike you guys.
[04:57:45] <ssi> not terrible, but not great
[04:58:01] <Jymmm> In certain ways I'd prefer ADSL, the latency was MUCH less.
[04:58:01] <ssi> the shared loop thing really hasn't been an issue in my experience
[04:58:06] <ssi> ew
[04:58:08] <ssi> I hate latency
[04:58:15] <ssi> poor JT is on satellite
[04:58:25] <Jymmm> you must be a fscking gamer! lol
[04:58:30] <ssi> no, not a gamer
[04:58:32] <ssi> I just don't like latency
[04:58:40] <Jymmm> ah
[04:58:47] <ssi> I have to do a lot of remote shell work
[04:58:48] <PetefromTn_> I used to have satellite when we lived out in dah woods...
[04:58:50] <ssi> and I hate waiting for my keystrokes
[04:58:56] <Jymmm> Yeah, JT-Shop has the suck end of things. Poor bastard.
[04:58:57] <ssi> in fact this irc session is in a remote shell
[04:59:17] <ssi> over vpn no less :P
[04:59:23] <PetefromTn_> is it a conch shell?
[04:59:33] <ssi> yeah... every time I talk to you guys I can hear the ocean ;)
[04:59:37] <Jymmm> ssi: yeah yeah big woop
[04:59:39] <PetefromTn_> I love Conch Fritters man..LOVE EM'
[05:00:43] <PetefromTn_> Drove all the way to gatlinburg this weekend to try out a Cajun place called Crawdaddys because they had it on their online menu....Got there....NO FREAKIN' Conch Fritters.. BASTARDS!!!!
[05:00:55] <ssi> aww
[05:01:05] <ssi> i flew into sevierville a few times
[05:01:28] <PetefromTn_> They did have some delicious Gator Tails and some excellent mussels with andoille sausage..
[05:01:41] <PetefromTn_> WHAT and you did not let me know??!!
[05:01:50] <ssi> haha it was years ago
[05:02:52] <PetefromTn_> The calamari was good but a bit firm for my tastes.
[05:03:04] <PetefromTn_> I must be hungry er somethin'...

[05:03:48] <PetefromTn_> We have a little delicatessen here that serves fresh Gyros..
[05:04:41] <PetefromTn_> Ya know I bought my wife's SUV from a place in northern Atlanta that had a nice Greek diner...we ate there while they installed a brand new windshield in her car...
[05:04:59] <ssi> in town? might have been landmark diner
[05:05:00] <PetefromTn_> Best damn Gyro I ever had really...
[05:05:08] <ssi> that's in buckhead

[05:05:46] <ssi> that'd be 285
[05:05:53] <PetefromTn_> yup I think so..
[05:06:14] <PetefromTn_> it was off there the guy was a used car dealer working out of a buildings parking lot...
[05:06:28] <PetefromTn_> Got a good deal she loves her SUV..
[05:07:30] <ssi> :)
[05:08:11] <PetefromTn_> You still use your Lathe?
[05:08:17] <ssi> it's been down for ages
[05:08:22] <PetefromTn_> SOB...
[05:08:28] <ssi> as soon as the plasma table is fixed I'm gonna dive into the pneumatics
[05:08:34] <ssi> jt is gonna help me figure it out
[05:08:40] <ssi> trying to bribe him down here with beer and pizza and plane rides :)
[05:08:53] <PetefromTn_> That should work I think....
[05:09:00] <PetefromTn_> what is wrong with it?
[05:09:08] <ssi> the turret quit on me
[05:09:12] <PetefromTn_> SOB
[05:09:15] <ssi> I took it apart and found a broken shuttle valve
[05:09:19] <ssi> replaced it at great personal expens
[05:09:23] <ssi> was like $300 from hardinge
[05:09:30] <PetefromTn_> ouchie.
[05:09:31] <ssi> put it all back together and now it's worse
[05:09:45] <ssi> constant air leak, when you command a tool change it turns into a louder airleak
[05:09:47] <PetefromTn_> did you let the magic out er somethin'?
[05:09:49] <ssi> no motion
[05:09:51] <ssi> it's all pneumatics
[05:09:57] <ssi> and I'm stupid when it comes to pneumatics
[05:10:01] <PetefromTn_> pneumatic magic?
[05:10:07] <ssi> yea
[05:10:11] <ssi> I let the magic air out :)
[05:10:33] <PetefromTn_> Tell ya what, I will take that poor POS off your hands man.. You don't need the stress. You'll feel better.
[05:10:45] <ssi> trade ya for the cincy
[05:10:58] <PetefromTn_> Sorry man NEED the Cinci.
[05:11:01] <ssi> heheh
[05:11:08] <PetefromTn_> Need both damnit.
[05:11:10] <ssi> I'll give you a great price on it
[05:11:19] <PetefromTn_> Oh I am sure you will....
[05:11:26] <PetefromTn_> need a kidney?
[05:11:36] <ssi> I'd sell it for pretty cheap actually
[05:11:39] <ssi> just probably not all the tooling
[05:11:41] <PetefromTn_> how cheep?
[05:11:42] <ssi> I got raped on the tooling :)
[05:11:51] <PetefromTn_> I like cheeep.
[05:12:11] <ssi> maybe $3k with the computer and mesa gear and vfds and everything
[05:12:18] <ssi> and the 10 gallons of very expensive mobilmet in it :)
[05:12:39] <PetefromTn_> That is not bad really... Does everything else work?
[05:12:47] <ssi> yeah everything works great
[05:12:51] <ssi> it's a really super machine
[05:12:55] <ssi> once the turreet's running again :P
[05:12:59] <PetefromTn_> hows the spindle sound?
[05:13:03] <ssi> sounds fine
[05:13:10] <ssi> I've done some precision work on it
[05:13:13] <ssi> it'll hold tenths all day long
[05:13:21] <PetefromTn_> collets?
[05:13:35] <ssi> what about 'em? :)
[05:13:38] <PetefromTn_> Ya got a chuck for the monster?
[05:13:43] <ssi> I don't have a chuck
[05:13:48] <PetefromTn_> damn.
[05:13:55] <ssi> I've done bigger work in step collets
[05:14:02] <PetefromTn_> Whatsa 5c go up to?
[05:14:08] <ssi> 1-1/16
[05:14:22] <ssi> CHNC is 16C, which'd be a nice upgrade
[05:14:25] <ssi> 1-5/8
[05:14:37] <PetefromTn_> I got the 12x36 here that works for that larger stuff pretty good.
[05:14:57] <ssi> chucks for that spindle nose are out there, I jsut haven't managed to lay hands on one yet
[05:15:06] <PetefromTn_> Is it running 3 phase or single..?
[05:15:15] <ssi> takes single phase in
[05:15:20] <PetefromTn_> awesome.
[05:15:21] <ssi> have two VFDs in it
[05:15:27] <PetefromTn_> two?
[05:15:29] <ssi> 3hp for the spindle and a 1/4 for the coolant pump
[05:15:36] <PetefromTn_> aah just like my machine.
[05:15:49] <PetefromTn_> would be a perfect match for my mill really....
[05:15:52] <ssi> yeah
[05:16:00] <ssi> it's using the original drives and drive power supply
[05:16:07] <PetefromTn_> Oh that sucks..
[05:16:12] <ssi> they work
[05:16:24] <PetefromTn_> I know my original drives cost a MINT when they blew...
[05:16:33] <PetefromTn_> That is why I gutted the pig and went with new stuff..
[05:16:41] <ssi> I'd replace the drives with AMC drives if these went out
[05:16:54] <ssi> all the resolver work is figured out
[05:17:05] <ssi> pcw had to make me a special version of his resolver converter to do this machine
[05:17:16] <ssi> the resolvers are actually pretty nice
[05:17:19] <ssi> VERY high resolution
[05:17:30] <PetefromTn_> I almost bought a machine just like that a couple weeks ago that was in need of work.
[05:17:39] <PetefromTn_> it was like $1100.00...
[05:17:56] <ssi> yes they can be had cheap because nobody wants to deal with those tape fed controls
[05:17:56] <PetefromTn_> PCW is da man....
[05:18:53] <PetefromTn_> I don't have 3k right now but if you are not in a huge hurry I might be able to get it from you in awhile...
[05:19:07] <ssi> keep it in mind
[05:19:20] <ssi> I'm trying to unload machines so I can get out of this house
[05:19:24] <PetefromTn_> ya got any current pics of it? How are the ways..
[05:19:29] <ssi> ways are perfect
[05:19:37] <ssi> I replaced the big rubber wipers
[05:19:54] <ssi> when I got it, it had been sitting in one spot and the rubber rotted and kinda gunked up the way at the tail end
[05:20:02] <ssi> and there's some staining from that, but nothing that affects motion
[05:20:08] <ssi> those rubber bits were pretty expensive
[05:20:19] <PetefromTn_> isn't everything...
[05:20:19] <ssi> I had to replace a nickel bellows coupler on the X axis which was expensive
[05:20:30] <ssi> when I first tuned the axes, some high accel broke it
[05:20:43] <ssi> $88 for that little bastard
[05:21:01] <PetefromTn_> glad you can still get parts for it.
[05:21:05] <ssi> yep, from hardinge
[05:21:12] <ssi> good that you can get them
[05:21:15] <ssi> bad that you have to bust out the dollars
[05:21:19] <ssi> they are NOT cheap
[05:21:27] <PetefromTn_> bust out the wallet and weep...
[05:21:31] <CaptHindsight> anyone know a good fractional HP coolant pump for retrofits that will handle the occasional chip and sludge?
[05:22:33] <ssi> PetefromTn_: my plan is to get all this work done on the plasma table and really clean it up nice, get it working well, and see if I can sell it
[05:22:36] <ssi> then work on the HNC
[05:22:45] <PetefromTn_> good plan.
[05:22:48] <ssi> I can probably sell the little g0602 as a turnkey package
[05:22:55] <PetefromTn_> Wish I could afford to buy both from you...
[05:22:57] <ssi> the clausing's gotta go
[05:23:05] <ssi> it's a nice old lathe but the ways are very worn :(
[05:23:09] <PetefromTn_> don't want or need the hobby stuff.
[05:23:09] <ssi> so it'll probably go pretty cheap
[05:23:19] <ssi> and I have a reid 2C surface grinder that I can sell
[05:23:34] <ssi> once everything's gone I'll prolly sell my grizzly 7x12 bandsaw
[05:23:38] <ssi> which is a pretty nice saw
[05:23:39] <PetefromTn_> ya need 2 kidneys?
[05:23:45] <ssi> not yet :P
[05:23:54] <PetefromTn_> I already have a 7x12,,,love it.
[05:24:01] <ssi> yeah that was one of the best upgrades I made
[05:24:08] <ssi> moving up from hf 4x6
[05:24:13] <ssi> piece of junk
[05:24:15] <PetefromTn_> beats the shit outta the 4x6 huh...
[05:24:18] <ssi> yep
[05:24:32] <PetefromTn_> I use mine daily here..
[05:24:40] <ssi> yeah
[05:24:45] <ssi> ;i had to replace my blade recently
[05:24:47] <PetefromTn_> Right now the blade is tweaked a little but it still cuts so I have not swapped it.
[05:25:03] <ssi> I had the brilliant idea that I could cut two feet off a piece of 30mm profile rail with the bandsaw
[05:25:05] <PetefromTn_> Got caught in a piece of shit thin wallled pipe I cut for my neighbor..
[05:25:21] <ssi> made a dull spot on the rail and rubbed all the teeth off the blade :)
[05:25:30] <PetefromTn_> hard
[05:25:34] <ssi> yeah very hard
[05:25:45] <ssi> just one of those brainfart moments
[05:25:45] -!- ve7it has quit [Remote host closed the connection]
[05:25:49] <ssi> cut it with the abrasive cutoff saw
[05:25:52] <ssi> HF special
[05:25:56] <PetefromTn_> mine came to me used with some nasty heavy cutting oil in it..
[05:26:02] <ssi> I bought mine new
[05:26:14] <ssi> when I went to get the hardinge, I pulled a trailer through harrisburg
[05:26:15] <PetefromTn_> I cleaned that sludge out and switched to the same stuff I use in the mill... works great.
[05:26:21] <ssi> and decided on spur of the moment to visit the griz showroom
[05:26:24] <ssi> and impulse bought a bandsaw
[05:26:26] <PetefromTn_> bought mine for $200.00
[05:26:30] <ssi> nice deal
[05:26:32] <ssi> I paid like $800 :P
[05:27:02] <PetefromTn_> thats about what they cost I think for the most part.
[05:27:06] <ssi> yep
[05:27:10] <ssi> I don't regret it
[05:27:16] <PetefromTn_> nope they work real good.
[05:27:25] <PetefromTn_> I have cut lots of stuff with it. All the time really.
[05:27:38] <PetefromTn_> I want to make a nice vertical setup for it but never get around to it.
[05:27:52] <ssi> I have a vertical bandsaw around
[05:27:54] <ssi> not a great one
[05:27:59] <ssi> but it keeps me from screwing with the horizontal
[05:28:06] <PetefromTn_> is it a metal cutting one?
[05:28:10] <ssi> no
[05:28:11] <ssi> but it can :)
[05:28:18] <ssi> mostly aluminum
[05:28:34] <PetefromTn_> yeah I know. I burnt the rubber wheels off my old wood cutting bandsaw and had to source new ones.
[05:28:43] <PetefromTn_> Trying to cut some sheetmetal.
[05:28:47] <PetefromTn_> It worked...sorta.
[05:29:04] <PetefromTn_> Cost me more to fix it than I wanted tho.
[05:29:32] <ssi> heheh
[05:29:41] <PetefromTn_> I did make a little metal plate that screws onto the guides for vertical stuff. It is just not near big enough.
[05:29:57] <PetefromTn_> Need to make something that has a leg that goes to the ground and clamps on somehow.
[05:30:08] <PetefromTn_> The saw is quite capable vertically actually...
[05:30:35] <PetefromTn_> Way better than my 4x6 even after I modded the piss out of it. I sold it when the second motor died on it.
[05:30:41] <ssi> heheh
[05:31:12] <PetefromTn_> would love a nice doall or similar vertical.
[05:31:22] <ssi> oh did I tell you about the punch press I got?
[05:31:25] <ssi> sorta got
[05:31:32] <PetefromTn_> jeez man you are starting to piss me off here..
[05:31:34] <ssi> haha
[05:31:43] <ssi> it's a diacro VT-19 turret punch
[05:31:48] <ssi> not a remarkably capacitous machine
[05:31:53] <ssi> like 19"x24" or something like that
[05:32:01] <ssi> has the same GE 550 control the HNC had
[05:32:03] <ssi> tape fed mess
[05:32:04] <PetefromTn_> nice..
[05:32:09] <ssi> I haven't done anything with it yet
[05:32:12] <ssi> I don't technically own it
[05:32:22] <ssi> this guy delivered it to my hangar and I have an arrangement
[05:32:26] <ssi> I'm storing it for free
[05:32:27] <PetefromTn_> oh one of those deals lOL
[05:32:36] <ssi> if I convert it, he owns $3k worth of whatever it ends up worth
[05:32:55] <ssi> it wouldn't be worth 3k, but he's got over 100 dies for it
[05:32:57] <ssi> so maybe it is
[05:33:14] <PetefromTn_> I gotta remember to send my 7i77 back to get repaired...keep forgettin.
[05:33:22] <ssi> what'd you do to it?!
[05:33:32] <PetefromTn_> smoked the shit out of it..
[05:33:52] <PetefromTn_> fried it like a thanksgiving turkey..
[05:33:58] <ssi> bad pete
[05:34:03] <PetefromTn_> yup...
[05:34:06] <ssi> haha I fried a 5i25, dunno if you saw that
[05:34:36] <PetefromTn_> but it is working again after a new set of relays, a new 24 volt power supply and a new 7i77 thankfully...
[05:34:40] <PetefromTn_> nope.
[05:34:58] <ssi> I switched the plasma table to use ohmic sensing instead of floating head
[05:35:11] <ssi> and neglected to provide a way to decouple that line from the io pin when the torch fires
[05:35:19] <ssi> so I fired the torch and put 400V or so into an io
[05:35:21] <PetefromTn_> doh!!
[05:35:29] <ssi> yuuuup
[05:35:51] <PetefromTn_> sounds like what I did... I put 220 volts into the 24 volt power supply!
[05:36:04] <ssi> :D
[05:36:05] <PetefromTn_> on the output LOL
[05:36:19] <ssi> yea so you actually smoked it huh
[05:36:23] <ssi> I didn't smoke the 5i25
[05:36:28] <ssi> I think I just killed one of the bus switch chips
[05:36:31] <PetefromTn_> made some nice pretty lights I can still see when I blink..
[05:36:32] <ssi> I may try to repair it myself :P
[05:36:49] <ssi> I have a spare 5i25 on hand actually, earlier I got the propre firmware flashed on it and installed it in the machine
[05:36:52] <ssi> and my motion is working again
[05:36:53] <ssi> so that's good
[05:37:23] <PetefromTn_> yeah smoked the linear power supply real quick. the 7i77 was a casualty of the war.
[05:37:44] <PetefromTn_> Apparenlty the IO section may just need a chip or something like that according to Pete..
[05:37:58] <PetefromTn_> The other Pete... the one who knows what the hell is going on actually.
[05:38:03] <ssi> yeah that's what I figured
[05:38:15] <ssi> the field io processor
[05:38:21] <PetefromTn_> yup.
[05:38:43] <PetefromTn_> I shudder to think what it would have cost me if I did that with the original control tho...
[05:38:47] <ssi> heheh
[05:38:49] <PetefromTn_> Woulda broke me..
[05:38:59] <PetefromTn_> This was bad enought but just a couple hundred clams.
[05:39:01] <ssi> man someone linked a cincy 750 with a 4th axis in alabama for cheap
[05:39:07] <ssi> and I almost considered going to get it
[05:39:30] <PetefromTn_> I know a guy on the zone that has some that he got after his building burned.
[05:39:40] <PetefromTn_> He was apparently getting them setup and working.
[05:39:46] <PetefromTn_> perhaps it did not work out.
[05:40:00] <PetefromTn_> He contacted me occasionally about my buildup
[05:40:12] <PetefromTn_> mine is still not completed.
[05:40:24] <PetefromTn_> but at least I can make parts on the thing now.
[05:40:41] <PetefromTn_> Been making some pretty cool parts for precision airguns.
[05:41:02] <ssi> ya I've seen it :)
[05:41:16] <PetefromTn_> Sounds like you got enough toys already needing some love over there.
[05:41:29] <ssi> yeah :/
[05:41:41] <PetefromTn_> how big is that plasma?
[05:41:44] <ssi> 4x4
[05:41:49] <PetefromTn_> nice
[05:42:02] <PetefromTn_> I could use that machine here for sure.
[05:43:11] <ssi> when I get everything working right, I'm not gonna want to get rid of it :P
[05:43:31] <PetefromTn_> Well I better get my ass to bed I got some work to do in the morning. Still waiting on some parts I ordered for this other airgun. Paid for 2 day priority and got an email from USPS but it says it was never picked up for three days now...
[05:43:35] <ssi> yea
[05:43:38] <PetefromTn_> I'm sure...
[05:43:53] <PetefromTn_> how much ya got in it so far?
[05:44:02] <ssi> a lot
[05:44:02] <ssi> :P
[05:44:12] <PetefromTn_> yeah
[05:44:20] <ssi> probably $7k or so
[05:44:20] <PetefromTn_> Shits spensive...
[05:44:30] <PetefromTn_> ooh ouch.
[05:44:39] <PetefromTn_> For that much I would want a 4x8..
[05:44:46] <ssi> 4x8 torchmate is $20k
[05:44:55] <PetefromTn_> screw that I would build my own.
[05:45:10] <PetefromTn_> amazing people pay that much for them.
[05:45:14] <ssi> i could have done it cheaper
[05:45:18] <ssi> but I did it with profile rail
[05:45:25] <ssi> and 8' worth of profile rail is going to cost you out the ass
[05:45:36] <ssi> I bought my rails cheap, lucky finds
[05:45:37] <PetefromTn_> I guess it just comes down to do you want to make money and parts or make a damn machine.
[05:45:39] <ssi> and I still have $1k in rails
[05:46:00] <PetefromTn_> I would probably build that mechmate machine into a dual plasma/router setup..
[05:46:33] <ssi> I wanted to do that originally
[05:46:39] <ssi> but they're not really compatible
[05:46:45] <ssi> water table vs router bed
[05:46:56] <ssi> rigidity you need for a router is overkill for plasma
[05:47:01] <PetefromTn_> do you have a water table on yours?
[05:47:03] <ssi> one thing I'd love to have on this machine would be a plate marker
[05:47:03] <ssi> yes
[05:47:11] <ssi> or a center punch at least
[05:47:21] <ssi> cause plasma isn't great for small holes
[05:47:33] <ssi> so it'd be nice to be able to center punch all the drill hits under cnc
[05:47:38] <PetefromTn_> have you actually run it yet?
[05:47:43] <ssi> oh yeah I've run it for years
[05:47:47] <ssi> I'm just doing a big rebuild
[05:48:12] <ssi> https://www.youtube.com/watch?v=b3rhhnSkbfw
[05:48:15] <PetefromTn_> what is the thickest cut you can make that does not look like ass?
[05:48:21] <ssi> thicker's better actually
[05:48:26] <ssi> it'll pierce and cut 3/8 happily
[05:48:38] <ssi> it'll do 1/2, but piercing 1/2 is hard on the consumables
[05:50:00] <PetefromTn_> looks nice man but I swear it does not look like there is anything to this kind of machine really. Basic as hell.
[05:50:15] <ssi> it's pretty basic
[05:50:38] <ssi> but scratchbuilding machines is hard no matter what :)
[05:50:58] <PetefromTn_> I certainly could use one here maybe I need to just break down and build one.
[05:51:05] <ssi> do it
[05:51:13] <PetefromTn_> Yeah I have built quite a few machines over the years..
[05:51:15] <ssi> I know what I'd do differently if I had it to do over
[05:51:23] <PetefromTn_> buy one LOL
[05:51:25] <ssi> nah
[05:51:29] <ssi> I'd build another in a heartbeat
[05:51:35] <ssi> I wouldn't use profile rail for it tho
[05:51:49] <PetefromTn_> I swear you could build two and make money just selling the one.
[05:51:50] <ssi> and rather than a raised gantry, I'd do high sides
[05:51:58] <PetefromTn_> like the mechmate...
[05:52:01] <ssi> ya
[05:52:11] <PetefromTn_> Flattish gantry and high sides...
[05:52:15] <PetefromTn_> very easy and simple.
[05:52:17] <ssi> yep
[05:52:18] <PetefromTn_> less flex
[05:52:24] <PetefromTn_> great design really.
[05:52:26] <ssi> and I'd do belt drive
[05:52:34] <ssi> not super thrilled with the rack&pinion
[05:52:35] <PetefromTn_> belt or chain I guess.
[05:52:46] <ssi> I converted the X axis to belt during this retrofit
[05:52:57] <ssi> my only concern is i may need gear reduction on the stepper
[05:53:03] <PetefromTn_> a good timing belt kicks ass when you don't need crazy precision.
[05:53:07] <ssi> cause my fullstep size is 0.014 :/
[05:53:25] <ssi> and lcnc was doing something weird the other day
[05:53:29] <PetefromTn_> I would probably use servos.
[05:53:30] <ssi> if I do incremental jog
[05:53:37] <ssi> I can hit 0.010 jog ten times and the axis won't move
[05:53:42] <ssi> and I effectively lose motion that way
[05:53:49] <ssi> yeah servos would be a nice upgrade for this machine
[05:53:51] <PetefromTn_> NOT GOOD.
[05:53:56] <ssi> I know it's not good
[05:54:00] <ssi> and I don't know why it was doing that

[05:54:37] <PetefromTn_> I like how the mechmate uses hand ground rails.
[05:55:00] <ssi> I might try ahren's bearing system
[05:55:09] <ssi> now that I've seen it in person, I actually am impressed by it
[05:55:10] <PetefromTn_> its as precise as you are able to cut it.. take your time and be careful and it will be really nice.

[05:57:16] <PetefromTn_> that is basically how the mechmate works sorta.
[05:57:44] <PetefromTn_> I could machine some mounts like that easy on the Cinci.
[05:57:54] <ssi> yeah see I still have no cnc mill :(
[05:58:19] <ssi> I could punt and buy a retrofit kit for my bridgie
[05:58:21] <ssi> but that seems sill
[05:58:25] <ssi> cause I like having a manual
[05:58:28] <PetefromTn_> and I have no CNC lathe :(
[05:58:35] <ssi> I have two :(
[05:58:43] <PetefromTn_> TWO!!
[05:58:47] <PetefromTn_> Bastard!!!
[05:58:52] <ssi> three lathes, two cnc
[05:59:03] <PetefromTn_> LOL
[06:00:09] <PetefromTn_> I am trying to find work for this thing all the time occasionally get some cool parts to make but it sits alot. Need to get it going before I think too seriously about another CNC machine I guess or my wife will kill me.

[06:00:30] <PetefromTn_> laugh it up fuzzball...
[06:00:59] <archivist> I haz two lathes in the kitchen

[11:16:52] <SpeedEvil> Spindle, and a big carbide fly-cutter.
[11:17:08] <Valen> pshaw
[11:17:13] <Valen> plasma torch that sucker
[11:17:38] <Valen> I believe they are looking to automate the long wall mining operations and much more of the underground mining these days
[11:17:43] <SpeedEvil> yeah.
[11:17:55] <Valen> but they do actually use plasma for making foundations
[11:18:08] <SpeedEvil> It makes a crust?
[11:18:21] <Valen> they drill a hole, then run a plasma torch down it to turn it into glass basically

[12:41:56] -!- paideia [paideia!~paideia@] has joined #linuxcnc
[12:46:59] <Jymmm> I know I can use a "V" Slot to center a round object. Is there something I can use to center a rectangular object?
[12:48:37] <mozmck> vise and measuring tools
[12:49:11] <Jymmm> Yeah, no. This is for an alignment jig
[12:49:40] -!- balestrino has quit [Ping timeout: 240 seconds]
[12:49:57] <Jymmm> The objects width it arbitrary.
[12:50:26] <Jymmm> as it can vary.
[12:51:14] <mozmck> maybe a centering vise then.
[12:51:45] <mozmck> http://www.grizzly.com/products/Precision-Self-Centering-Vise/H7576
[12:52:33] <Jymmm> Do they come in 1/8" tall versions?
[12:52:41] <mozmck> Of if that's too cheap: http://www.kurtworkholding.com/self-centering-vise-p-1190-l-en.html
[12:53:30] <mozmck> total height?
[12:53:35] <Jymmm> It doens't need to be clamped
[12:53:44] <Jymmm> total height, yes.
[12:54:51] <mozmck> I wouldn't think so. What is this for?
[12:55:42] <Jymmm> See, for round objects I can just create a plate with a V-Slot, anyting round placed in the slot is perfectly centered. I just need the same thing for rectangular objects.
[12:56:52] <mozmck> Yes, but you can't just make a slot for them if they will vary in width. What is the application though? Drilling holes?
[12:56:55] <Jymmm> Alignment jig for my laser.
[12:58:25] <mozmck> can't think of anything as simple as a slot. a fence adjusted with a screw would work and could be made thin.
[12:59:36] <mozmck> still have to measure though.
[12:59:48] <Jymmm> Yeah, the only thing I could think of is a "staircase", but that would only work for known widths.
[13:02:29] <jdh> two diagaonal corners with wheels, cable, constraints?
[13:02:54] <Jymmm> How do centering vises work? Both jaws close at the same time, but how do you know that's "center" and not shifted one side or another?
[13:03:26] <Jymmm> jdh: Say that again?
[13:03:39] <mozmck> the screw has left and right hand threads.
[13:04:44] <Jymmm> mozmck: Right, but when the jaws are closed 100% with nothing in them, how do you know that's "center", and not center -10 ?
[13:04:44] <mozmck> so if everything is tight and accurate, the jaws always move the same distance opposite ways
[13:05:08] <jdh> you will have to reference whatever it is at least once
[13:05:18] <mozmck> You have to center the whole vise obviously to start with.
[13:05:28] <Jymmm> jdh: Does that ever change?
[13:05:45] <jdh> if you move it
[13:05:53] <Jymmm> So, no. ok
[13:06:03] <Jymmm> Just asking =)
[13:06:28] <Jymmm> I thought there might have been calibrated center line on the vise themselves
[13:06:58] <mozmck> There might be - I don't know.
[13:07:03] <Jymmm> k
[13:09:01] <Jymmm> jdh: what were you saying about diaganol corners?
[13:09:35] <jdh> like a pantograph mechanism sort of.
[13:09:54] <jdh> where the two corner parts come in/out together
[13:10:13] <Jymmm> Oh, hmmm.
[13:12:01] <Jymmm> The reason I was asking how a centering vise works is I was thinking like the jaws of a pair of calipers sorta thing for centering rectangular objects.

[14:55:17] <JT-Shop> I have some steel parts cut with the plasma and I need to deburr them. I have a sand blaster but that sucks
[14:55:41] <JT-Shop> I also have a concrete mixer can I use that with some local media to clean parts?
[14:56:29] <mozmck> I'm sure you could! tumble them around in sand or gravel a little
[14:57:16] <mozmck> I usually used a file or junk chisel to remove the slag, and a flap sanding disk on an angle grinder.
[14:57:16] <_methods> needler
[14:57:20] <archivist_herron> we used a barrel to clean parts, you can buy various compounds for for rough to polish
[14:57:27] <ssi> JT-Shop: I'd love to see some pics of what comes off your plasma
[14:57:35] <ssi> and what kind of burr you're talkin

[14:59:36] <ssi> JT-Shop: i get a little roll of dross
[14:59:42] <JT-Shop> probably not something you can find at Menards
[15:00:09] <ssi> I usually can knock it off with another heavy chunk of plate, but it's usually a pain in the ass
[15:00:21] <_methods> i'm talking about the flapper disks not the flapper wheels
[15:00:22] <mozmck> JT-Shop: the flap sanding wheels work well. If the cut is good the dross usually knocks off quite easily.
[15:00:30] <JT-Shop> for me it depends on how dirty the metal is, I usually take a small ball peen hammer and tap the edge

[15:06:03] <mozmck> IoT - latest buzzword, should tack it on the linuxcnc description somewhere
[15:06:17] <archivist_herron> you need ear muffs for a tumbler :)
[15:06:24] <ssi> I tried vibratory tumbling with those green diamonds
[15:06:29] <ssi> it didn't work remarkably well
[15:06:40] <jdh> JT: the guy I sell my shark teeth two has 3 that look like that.
[15:06:41] <JT-Shop> I know vibratory finishing is the best/fastest but I don't do this often enough to get a $5k machine
[15:07:17] <JT-Shop> yea the tumbler would have to be outside while running
[15:07:23] <archivist_herron> ours was homebrew wooden 6 or 8 sided
[15:07:47] <mozmck> acid dip for several hours and rinse well. slag pretty much falls off.
[15:08:04] <jdh> sided vs. round sounds like it woudl tumble better
[15:08:07] <JT-Shop> I designed some tumblers for the nail factory I used to work for and they worked so well they still use that design
[15:08:28] <JT-Shop> mozmck, what kind of acid?
[15:08:36] <mozmck> hcl
[15:08:50] <Jymmm> Heh, "Nail factory", sounds like something from the 1800's
[15:08:53] <mozmck> Don't know if that's best for your objective or not.
[15:09:16] <ssi> I setup an anodizing station awhile back
[15:09:23] <mozmck> sure gets it clean for finishing.
[15:09:23] <ssi> hated having to have acid around
[15:09:29] <ssi> and strong alkaline too
[15:09:40] <ssi> ate up my clothes, was worried about what it'd do to the machines
[15:09:59] <JT-Shop> I have muriatic acid or battery acid on hand

[15:13:46] <mozmck> I don't remember now - it's been a number of years. I think I might have rinsed, then soaked in water with baking soda.
[15:14:09] <mozmck> I don't remember how dilute the acid solution was either.
[15:15:02] <JT-Shop> I used that to de-rust the inside of my '56 tractor gas tank
[15:15:25] -!- dybskiy has quit [Ping timeout: 264 seconds]
[15:15:32] <mozmck> Yes, that's partly why we used the acid, removed *all* rust before power coating.
[15:15:37] <JT-Shop> looks like I didn't get the bottle clean as it is making my shelves rust
[15:18:13] <Jymmm> JT-Shop: Unless it came sealed in a plastic bag, I've never had anything "clean".
[15:18:38] <Jymmm> Even then, I've had acid on the bag too.
[15:19:25] <jdh> I broke down and ordered my chinese router
[15:19:39] <Jymmm> My hands are sensative to acids. Even giving someone a jump start I can feel the acid on my hands. I always carry baking soda as just water/soap never work.
[15:22:20] <jdh> wear gloves?
[15:26:46] <Jymmm> Not always practical, and I don't want to eat thru my leather ones
[15:27:03] <mozmck> I washed a battery off once pretty thoroughly, then carried it across the yard. A little water off the top fell off on my knee and before I got across the yard the knee of my jeans ripped out.
[15:27:07] <Jymmm> jump starting that is. Other times, I do
[15:27:23] <ssi> mozmck: yeah I've been through a lot of that crap
[15:27:48] <Jymmm> mozmck: you suck at washing is all =)
[15:27:53] <mozmck> I didn't realize it would do something that quickly at the time.
[15:27:53] <ssi> airplane batteries are mostly Gill pieces of shit, and you have to fill them when you get them, and they have ball checkvalve cell caps
[15:27:56] <ssi> so there's always acid everywhere
[15:28:18] <ssi> it's awesome cause they leak acid in their battery box
[15:28:30] <mozmck> I think some acid may have seeped from under the cap, but it would have been diluted.
[15:28:32] <ssi> always good to see the corrosion in your freakin airframe because of your stupid pos battery
[15:28:45] <mozmck> heh, you get to pay 4x for that too!
[15:29:03] <ssi> yeah the last gill I bought I had to pay over $300 for
[15:29:15] <ssi> because I was stranded in new jersey and at the mercy of the mechanic on the field that happened to have one
[15:29:16] <Jymmm> SUCKER

[15:32:13] <ssi> yes, tcraft is designed to do so
[15:32:34] <ssi> it's probably a c65 or c90, low compression, easy to flip through
[15:32:40] <mozmck> yes, but most things I've seen have you stand in front so you'll get sucked into the prop :)
[15:32:41] <ssi> light prop, plus you can get to it from the cockpit
[15:32:54] <ssi> and it's a taildragger so the prop is up in the air, so you have a big swing angle
[15:32:58] <mozmck> yes, c65 I think
[15:33:15] <ssi> cherokee is 150hp, higher compression, big heavy prop, and you have to walk all the way around the wing to get in once it's running

[16:00:45] <JT-Shop> few minutes in hcl, baking soda rinse, fresh water rinse, rinse in plasma quench
[16:00:58] <JT-Shop> yea, you should see the rusty crap I cut them from

[16:01:08] <CaptHindsight> 1-2mm of lash :) the motor bearings were the stop on one end

[16:05:02] <ssi> I'm trying to remember what the deal was with anodizing
[16:05:07] <ssi> I was using sulfuric, but
[16:05:08] <JT-Shop> and turned it black
[16:05:13] <ssi> the lye would eat the surface
[16:05:16] <ssi> and the acid wouldn't
[16:05:29] <JT-Shop> for an acid etch?
[16:05:34] <ssi> for anodizing

[16:07:20] <JT-Shop> yep
[16:07:30] <JT-Shop> and a degreaser up front
[16:08:05] <archivist> the filler was lanolin hand rubbed on in those days
[16:08:07] <JT-Shop> etch is only needed for some alloys, I use 6061 which does not need the etch

[19:37:30] <CaptHindsight> can the Google drive be setup as shared reads like a web file server?
[19:38:02] <_methods> i'm not sure
[19:38:06] <_methods> i rarely use mine
[19:39:06] <_methods> http://xmodulo.com/2013/10/mount-google-drive-linux.html
[19:39:17] <_methods> looks like you can use ocamlfuse
[19:39:23] <_methods> and mount like any other drive
[19:40:04] <CaptHindsight> say you have compressed binaries -500MB and only want shared reads for many, and write only for admin
[19:40:21] <_methods> yeah i don't know about permissions in there
[19:40:25] <_methods> i'm assuming so
[19:40:31] <CaptHindsight> anonymous reads
[19:40:35] <_methods> yeah
[19:40:43] <CaptHindsight> they probably don't allow that
[19:40:51] <_methods> my plan was maybe to use it for my plex server
[19:40:57] <_methods> keep all my movies heheh on there
[19:41:24] <_methods> don't even touch my home server
[19:41:35] <_methods> have a seed box funneling movies into my google drive
[19:41:46] <_methods> then mount the google drive in my plex media server
[19:43:38] <_methods> https://developers.google.com/drive/v2/reference/permissions/update
[19:45:09] <CaptHindsight> I wonder how many GB and users before they throttle the connection?
[19:45:23] <_methods> i have no idea
[19:45:26] <CaptHindsight> to truly replace dropbox
[19:45:28] <_methods> it's google so
[19:45:39] <_methods> they may be tryin to kill dropbox and bitcasa
[19:45:44] <ssi> oh man that was stressful :P
[19:46:20] <_methods> what?
[19:46:43] <ssi> there's a company that does job interviews via live assesment, they build you a vm and give you a set of timed tasks
[19:46:47] <ssi> some sysadmin tasks, some programming tasks
[19:46:50] <ssi> 60 minutes to do it
[19:46:58] <_methods> ah cool
[19:47:09] <ssi> when your time is up it just dumps you out of the vm
[19:47:45] <_methods> kobayashi maru
[19:49:37] <CaptHindsight> https://developers.google.com/drive/web/manage-downloads at the bottom
[19:50:12] <CaptHindsight> so it should work
[19:50:23] <_methods> yeah
[19:50:29] <_methods> nice sdk for it too
[19:50:35] <_methods> you can even convert docs
[19:50:51] <_methods> examples in 7 languages
[19:51:08] <CaptHindsight> this could even replace imagebin
[19:51:27] <_methods> i mean $10/month for unlimited storage
[19:51:32] <_methods> i'll find a use for that
[19:51:53] <CaptHindsight> public stuff you don't care about keeping private
[19:51:57] <_methods> exactly
[19:52:18] <ssi> i want to build myself a decent image hosting service that I can use quickly
[19:52:24] <ssi> there's nothing out there I've been happy with
[19:52:25] <CaptHindsight> or if it disappears due to some "software glitch"
[19:52:34] <ssi> I end up using twitter as that
[19:52:40] <ssi> cause I can take a pic with my phone and tweet it, and it's hosted
[19:52:43] <ssi> kinda terrible
[19:52:48] <CaptHindsight> yeah
[19:52:53] <_methods> well i don't trust google
[19:52:56] <_methods> after the reader thing
[19:53:01] <ssi> wise not to trust them :P
[19:53:01] <_methods> they love to cancel shit
[19:53:07] <ssi> the storage and hosting isn't a problem for me
[19:53:10] <_methods> well besides the spying thing
[19:53:17] <_methods> they just love to kill projects
[19:53:19] <ssi> I've got a colo'd server with 16TB raid6 and 2500GB/mo bandwidth
[19:53:24] <_methods> jesus
[19:53:26] <ssi> and it's almost unutilized as it is
[19:53:27] <_methods> how much is that?
[19:53:37] <ssi> $165/mo, including the two netblocks I have
[19:53:40] <ssi> have routed netblock and everything
[19:53:54] <ssi> and it's an esx server, so as many vms as I can run on it at atime
[19:54:03] <_methods> damn that's kinda nice
[19:54:16] <_methods> and you ahve access to 2 netblocks?
[19:54:23] <ssi> yeah... yet another of my stupid projects that costs me money every month but I do nothing with
[19:54:29] <_methods> who the hell is that with
[19:54:36] <ssi> yeah there's a little netblock that is on the front side, that they use to route the big netblock back to me
[19:54:42] <ssi> ubiquity hosting
[19:54:45] <_methods> hmm
[19:54:50] <ssi> it's in telx in downtown atlanta
[19:54:51] <CaptHindsight> that is low cost enough to resell space on
[19:54:55] <ssi> yeah
[19:54:57] <_methods> yeah
[19:55:06] <_methods> i want in lol
[19:55:11] <_methods> you go to freeside?
[19:55:12] <ssi> heheh
[19:55:15] <ssi> naw
[19:55:25] <_methods> you in atlanta?
[19:55:27] <ssi> yeah
[19:55:30] <ssi> a long time ago I wanted to
[19:55:39] <ssi> and then it was like "oh you gotta get sponsored and do work and blah blah"
[19:55:39] <_methods> one day i wanna get down there and check it out
[19:55:43] <ssi> and I said fuck that
[19:55:46] <_methods> oh yeah
[19:55:48] <_methods> no thank you
[19:55:49] <ssi> I have more equipment than everyone else there combined
[19:55:52] <_methods> yeah
[19:55:52] <ssi> they should be begging for me to join
[19:56:05] <_methods> just wondered
[19:56:10] <_methods> looked like a decent space
[19:56:11] <ssi> just seemed culty
[19:56:13] <ssi> or fratty
[19:56:14] <ssi> or something
[19:56:36] <_methods> most of those spaces are full of asperger nut jobs anyways
[19:56:41] <ssi> yeah
[19:56:46] <ssi> and these days, just tons of glue gun kids
[19:56:50] <_methods> omg
[19:57:15] <ssi> don't get me wrong, I've built a few glue guns, and they're handy for what they are
[19:57:25] <ssi> but the freakn glue gun kids treat them like they're the second coming of christ
[19:57:26] <_methods> they're fun i have 2 of em

[20:17:21] * SpeedEvil wishes nitrogen was easily usable as a shield gas
[20:17:34] <_methods> it's not?
[20:17:41] <ssi> it's too light I think
[20:17:53] <_methods> we use it all day on laser
[20:17:55] <ssi> argon works well cause it's denser than air, and sinks around your weld area
[20:18:08] <_methods> use it to purge beam path too
[20:18:54] <Loetmichel> ssi: it isnt to light
[20:19:19] <Loetmichel> but it tends to react with the molten metal
[20:19:24] <Loetmichel> it is not iniert
[20:19:26] <Loetmichel> inert
[20:19:30] <ssi> ah
[20:20:20] <_methods> http://en.wikipedia.org/wiki/Inert_gas
[20:20:34] <Loetmichel> and you dont want to have nitrogen in your steel/aluminium welds
[20:20:45] <Loetmichel> makes them brittle iirc
[20:22:00] * JT-Shop can't believe how clean these parts are and how many hours I saved over blasting
[20:22:09] <ssi> JT-Shop: :D
[20:22:24] <SpeedEvil> ssi: helium is very commonly used in welding.
[20:22:35] <SpeedEvil> JT-Shop: electrolysuys?
[20:30:33] <JT-Shop> hcl
[20:32:00] <SpeedEvil> Ah
[20:33:29] <ssi> I ordered one of the shapeoko kits
[20:33:36] <ssi> might be a good base for building a pick'n'place
[20:37:51] <jdh> what are you picking and placing?
[20:38:44] <mozmck> JT-Shop: glad it worked!
[20:40:32] <cpresser> _methods: what materials are you cutting with the laser?
[20:41:14] <cpresser> _methods: and which laser? i am still unsure if i should try nitrogen-air-assist for my 80W Co2-Laser when cutting acrylic or wood
[20:41:47] <SpeedEvil> Air assist is needed for wood
[20:41:56] <SpeedEvil> Makes it much, much bettee
[20:41:59] <SpeedEvil> R
[20:42:08] <JT-Shop> mozmck, thanks it worked great. I just need to refine my part handling a bit
[20:42:22] <Loetmichel> SpeedEvil: at least one should protect the lens vom getting fumes
[20:42:32] <JT-Shop> I can't believe that I'm done with those parts already
[20:42:41] <SpeedEvil> Yeah
[20:42:54] * cpresser has air-assist. but with air, not nitrogen
[20:43:07] <SpeedEvil> For that reason if no other, it doesn't make sense to not use it
[20:43:17] <SpeedEvil> Using nitrogen reduces burning
[20:43:19] <ssi> jdh: for assembling pcbs
[20:43:58] <cpresser> yes, but how much does it reduce the burning? how big is the difference when looking at the finished part? thats what i want to know
[20:44:00] <mozmck> ssi: I have 2 pick and place machines I need to get rid of. panasonic cm62p, fairly small footprint.
[20:44:26] <Loetmichel> even this homemader 80W laser of a friend had air assist for the lens -> http://bambuser.com/v/2270235
[20:44:31] <Loetmichel> (the green hose)
[20:45:03] <ssi> mozmck: what are you looking to get for them
[20:45:21] <Loetmichel> (was a bit scary to see that open system runnung with an 80W co2 tube running and no laser glasses
[20:45:57] <mozmck> ssi: oh, probably $600 each
[20:46:09] <ssi> I can't find any info about them
[20:46:27] <mozmck> tray feeders on both, paper manuals in english and japanese
[20:46:35] <mozmck> schematics.
[20:46:53] <ssi> what's the working area like
[20:47:07] <mozmck> I had one nearly running, but it would jump when jogging with the keyboard at times.
[20:47:08] <ssi> how many reels/trays/whatev

[20:47:22] <_methods> cpresser: this is on a 3200w trumpf laser

[20:47:56] <cpresser> _methods: okay... thats another league
[20:48:11] <ssi> mozmck: I might be interested... fetching them might be tricky
[20:48:14] <ssi> mozmck: got any pictures?
[20:48:23] <mozmck> I hate to just leave them sitting. Worst case I'll tear them down and sell parts.
[20:48:24] <_methods> yeah
[20:48:25] <_methods> hehe
[20:49:04] <cpresser> mozmck: i might also be interested in a pick-n-place machine... where are the machines now?

[20:50:37] <mozmck> heavy - maybe 1000 lbs
[20:50:38] <mozmck> each
[20:50:42] <ssi> ok
[20:50:55] <ssi> is important because I can pull a trailer with my car, but I'm limited to 2000lb
[20:51:03] <ssi> be nice to be able to get both of them on a trailer, but sounds like that's not happening
[20:51:05] <mozmck> oh.
[20:51:16] <ssi> can bring a truck, but car gets 50mpg, truck gets 20
[20:51:17] <ssi> :)
[20:51:36] <mozmck> yeah, that makes a difference.
[20:51:37] <cpresser> damm.. wrong continent for me to pick it up :/
[20:51:49] <ssi> and there's a reasonable chance I might want both
[20:51:50] <mozmck> where are you cpresser?
[20:51:55] <cpresser> europe/germany
[20:52:05] <mozmck> long ways away!
[20:52:30] <mozmck> oh, there are lots of feeders with these - 30 or so I think.
[20:52:56] <ssi> were you intending to convert it to lcnc?
[20:53:04] <mozmck> several sizes of reel and tube feeders.
[20:53:23] <mozmck> I had thought of it if I couldn't get the built in software to work.
[20:53:45] <ssi> looks like it might be a big pain in the ass :P
[20:54:10] <mozmck> Nearly had that working but we wound up using an outside board shop to assemble and I lost incentive and time to play with them.
[20:54:34] <mozmck> Yes, there are *lots* of inputs and all.
[20:55:34] <mozmck> they move fast though, and will place down to 0603 in size.
[20:56:25] <mozmck> video cameras for teaching and fiducial reading
[20:56:31] <ssi> nice
[20:56:51] <ssi> yeah it could be worthwhile... big machine tho
[20:57:24] <mozmck> I have far too many projects and am trying to clear some out
[20:57:29] <ssi> yeah you and me both
[20:57:41] <mozmck> These are not nearly as big as most PnP machines I've seen.
[20:57:53] <ssi> sure, but I'm talking about buildign a little desktop machine
[20:58:04] <mozmck> I see, yes bigger than that.
[20:58:21] <ssi> I'm fairly well out of space for large machines at this point :)
[20:58:55] <ssi> i'll keep it in mind tho
[20:59:27] <mozmck> I know the feeling. I just sold a 14" logan lathe, and have 2 more lathes and a mill I need to get rid of.

[21:40:12] <ssi> and the terminal block labeled IO0 corresponds to hm2's gpio.033
[21:40:19] <ssi> IO2 corresponds to .032
[21:40:25] <ssi> I can't find what IO1 and IO3 correspond to
[21:40:29] <Tom_itx> JT-Shop, your plans will get changed
[21:40:34] <Tom_itx> mine always seem to
[21:40:37] <JT-Shop> you need to look for 7i75 pins not hm2
[21:41:10] <JT-Shop> hm2_5i25.0.7i76.0.0.input-04
[21:41:19] <ssi> 7i75 is a passive protection module
[21:41:30] <JT-Shop> oh
[21:41:31] -!- Loetmichel has quit [Ping timeout: 244 seconds]
[21:41:37] <JT-Shop> that's different
[21:41:41] <Connor> ssi Which firmware you using ?
[21:41:43] <Tom_itx> if it's just protection it may not show up ata ll
[21:41:49] <ssi> g540x2
[21:42:14] <Connor> Hmm.
[21:42:30] <Connor> it may be treating that as a output...
[21:42:59] <Connor> g540 expects a parport ?
[21:43:11] <ssi> forget g540, it's not a factor
[21:43:15] <Connor> so, it would only have 5 inputs
[21:43:28] <Connor> I understand. But, the 5i25 is EMULATING a parport.
[21:43:37] -!- FreezingCold has quit [Ping timeout: 244 seconds]
[21:43:51] <ssi> yes, and the7i75 is a 17 io parport protection board
[21:44:04] <ssi> and looks like all the io work except for four, one daughterboard
[21:44:06] <ssi> looking at the manual now
[21:44:20] <Connor> right. with only 5 inputs ?
[21:44:25] -!- mhaberler has quit [Quit: mhaberler]
[21:44:27] <ssi> dude
[21:44:30] <ssi> forget g540
[21:44:34] <ssi> it's not a factor
[21:45:10] <ssi> no
[21:45:15] <ssi> it's hm2... all pins are gpio
[21:45:23] <ssi> don't scream at me if you're ignorant of fact
[21:45:49] <micges> ssi: what's the problem with 7i75?
[21:46:16] <ssi> micges: one of the terminal blocks doesn't respond to inputs... not sure if they're set as out only in hal or what exactly
[21:46:46] <Connor> but, did you not just say you was using the g540x2 firmware ? which would turn the gpio's to specific Inputs and outputs for emulating a parport.
[21:46:55] <ssi> that's not how it works
[21:47:34] -!- PetefromTn_ [PetefromTn_!~IceChat9@66-191-252-204.dhcp.kgpt.tn.charter.com] has joined #linuxcnc
[21:47:49] <ssi> and the fact that I have thirteen working inputs and four that aren't responding seems to fly in the face of your "theory"
[21:47:59] <JT-Shop> ssi to set a gpio to output you have to setp xxx.is_output 1 in hal somewhere
[21:48:31] <Tom_itx> set the direction and state
[21:48:44] <JT-Shop> General Purpose I/O pins on the board which are not used by a module instance are exported to HAL as full GPIO pins. Full GPIO pins can be configured at run-time to be inputs, outputs, or open drains, and have a HAL interface that exposes this flexibility. I/O pins that are owned by an active module instance are constrained by the requirements of the owning module, and have a restricted HAL interface.
[21:48:46] <ssi> JT-Shop: not doing that explicitly anywhere
[21:49:02] <JT-Shop> might be used by a stepgen or something
[21:49:17] <ssi> I have numstepgens = 5
[21:49:28] <ssi> which should be joints 0-4 plus the chargepump generator
[21:49:54] <ssi> and dmesg shows all p2 pins as gpio except one which is a pwmgen
[21:50:21] <ssi> lemme expliitly set pwmgens=1, that should disable the p2 pwm
[21:52:18] <ssi> but besides this issue, they're numbered oddly
[21:52:35] <JT-Shop> tis true, confusing to be flexible
[21:52:40] <DaViruz> 1,3,5,7,9...?
[21:52:41] -!- theorbtwo has quit [Ping timeout: 240 seconds]
[21:52:46] <ssi> the connector row opposite the db25 is numbered evens, 0, 2, 4, 6, 8, 10, 12, 14, 16
[21:52:56] <ssi> 0, 2, 4, 6 correspond to 33, 32, 31, 30
[21:53:03] <ssi> 8 is 29, 10 is 27
[21:53:07] <ssi> dafux :)
[21:53:33] amnesic_away is now known as amnesic
[21:53:57] <ssi> 12 is 25, 14 is 21
[21:54:06] <ssi> it just gets odder and odder
[21:54:11] <JT-Shop> your confusing me with the facts lol
[21:54:13] <Connor> http://pastebin.com/2DM4rfR6
[21:54:16] <JT-Shop> gotta run
[21:54:33] <ssi> 16 is 17
[21:54:59] <Connor> PinOuts for p2 and p3 for g540x2 firmware
[21:55:24] <ssi> Connor: that shows parport pins to hm2 io number, but not which terminal block they break out to
[21:56:28] <ssi> 1, 3, 5, 7 terminal blocks don't toggle any hm2 io in the 17-33 range

[22:00:16] <ssi> gpio18 is terminal 1 on '75?
[22:00:54] <micges> if you connected it to header on 5i25 then yes
[22:01:28] <ssi> none of the 17-33 have .is_output set
[22:02:05] <micges> terminal 0 works?
[22:02:49] <ssi> yeah
[22:02:52] <ssi> I bet it's this cable

[22:06:11] <Connor> Ribbon cable or parport type cable ?
[22:06:12] <micges> no wonder you got confused about pin numbers
[22:06:21] <ssi> no wonder indeed
[22:06:29] <Connor> Could be a laplink type cable..
[22:06:29] <ssi> parport type cable, but obviously not a parport cable
[22:06:35] <ssi> i think it's a leftover TDIF cable

[23:23:37] <LeelooMinai> I was searching for those weird cables for my digital indicator and most of them were expensive (at least $17,) but at the end I bought two of those: http://www.bgmicro.com/digitalcaliperwithdataoutputport.aspx
[23:24:16] <LeelooMinai> It has both a small-range indicator and the cable I need.
[23:25:17] <LeelooMinai> Now all I have to do is electronics for it - something with multiple channels for this kind of scale.\
[23:30:08] <LeelooMinai> Hmm
[23:31:08] <LeelooMinai> Now when I think about it, the mesa fpga cards could possibly decode those scales, if there's spare room besides the firmware on them.
[23:31:31] <LeelooMinai> They only send clock and one data stream - pretty simple.
[23:32:02] <LeelooMinai> Not sure though if those mesa cards are easy to exntend like that fimware-wise
[23:35:03] -!- asdfasd has quit [Ping timeout: 240 seconds]
[23:38:26] <zeeshan|3> LeelooMinai: i hope youre not trying to use those for feedback
[23:38:35] <zeeshan|3> cause the scales have a slow response time
[23:39:14] <LeelooMinai> I am just trying to get data from scales like that in general
[23:40:27] <LeelooMinai> For example, say I want to trace my x-y table with the indicator I have (it's 1μm) - I could automate it completelly and as tedailed map as I want.
[23:40:41] <LeelooMinai> detailed*
[23:40:45] <zeeshan|3> yes
[23:40:51] <zeeshan|3> but hopefully your indicators are accurate!
[23:40:52] <zeeshan|3> to begin with
[23:41:15] <LeelooMinai> This is in fact for now what I am interested it, as I need to come up with some table in next months
[23:41:25] <zeeshan|3> my chinese digital indicator is out by 5 thou over 1"
[23:42:14] <LeelooMinai> zeeshan|3: This matters not really. The one I have is claimed to be one micron, but once I get the system of getting data from those going, I can always get something better, if really needed.
[23:43:02] <zeeshan|3> i met an interesting person today
[23:43:07] <zeeshan|3> he wants to get some welding done
[23:43:20] <zeeshan|3> instead of giving me money, he wants to trade me 100lb of aluminum
[23:43:30] <zeeshan|3> he thought i wouldnt be interested
[23:43:33] <zeeshan|3> im like O_O asap he said that
[23:43:39] * zeeshan|3 likes aluminum
[23:43:40] <zeeshan|3> yum
[23:43:50] <LeelooMinai> I would take it without a blink too:)
[23:43:59] <zeeshan|3> its only like 25$ worth of welding
[23:44:01] <zeeshan|3> too
[23:44:03] <LeelooMinai> If I could/liked welding...
[23:44:22] <zeeshan|3> i don't really like welding either
[23:44:29] <zeeshan|3> but it's needed :p
[23:44:34] <LeelooMinai> It's kind of ugly imho:)
[23:44:43] <zeeshan|3> mig welding, stick welding, yea
[23:44:44] <zeeshan|3> not tig
[23:45:30] <LeelooMinai> Yes, it can be made nice looking and all, but still - it's difficult to have good control over it
[23:45:38] <zeeshan|3> ???
[23:45:43] <zeeshan|3> thats stick welding or mig
[23:45:49] <zeeshan|3> with tig it's highly controllable
[23:46:02] <zeeshan|3> you're controlling the depth of penetration (current) with your foot
[23:46:18] <zeeshan|3> you're controlling the filler rate with your right / left hand filler rod
[23:46:25] <LeelooMinai> It's still a bit of an art - you need a lot of experience to get consistent results.
[23:46:25] <zeeshan|3> and angle of gun
[23:46:53] <zeeshan|3> anyone can do it :P

[23:49:06] <LeelooMinai> wel,, yes, I realize some things need it. I used to ride MTB marathons - did tons of them, so I know a lot about bikes, frames, etc.
[23:50:06] <LeelooMinai> Though at the later stages of my "career" I had carbon-fibre frame anyways:) But for alu frames, yes, they cannot be screwed together.
