[00:00:56] <Encapsulation> 38-50mm average tool length it says, so I'm trying to use google to determine if I need to subtract that from the claimed clearance
[00:01:51] <Encapsulation> that might change everything, the omio cnc has a very nice 140mm z clearance and 140mm z travel
[00:02:17] <Encapsulation> so I need to rule out or confirm the ebay 6040 as a choice to continue narrowing the selection
[00:03:46] <jdh> down to 600, plus the other 8,231 you will find soon.
[00:03:52] <unfy> that includes the shank, yo.
[00:04:34] <Jymmm> jdh: Did you inlcude the cnc etch-a-sketch in that ?
[00:05:09] <Encapsulation> unfy, what about the shank?
[00:05:20] <Encapsulation> jdh, I'm actually down to just 3
[00:05:40] <Encapsulation> ebay 6040 omio x6-2200l or xzero 12"x30" machine
[00:05:55] <Encapsulation> prices $1300 $2500 $2500, respectively
[00:06:22] <Encapsulation> or I got crazy, and buy 25x30x7" xzero, but I think that would be too much at $3800
[00:06:33] <Encapsulation> I dont really NEED that much space
[00:06:49] <Encapsulation> I just dont like the small 12"x of the $2500 xzero
[00:07:08] <Encapsulation> this is assuming it comes down to x6-2200l vs xzero
[00:07:22] <Encapsulation> first I need to eliminate 6040 from the picture if it wont work
[00:07:26] <Encapsulation> what do you mean about shank unfy
[00:08:59] <Encapsulation> been looking into software as well, leaning towards freecad + meshcam + linuxcnc (I'm assuming I can output gcode from meshcam and use it with linux cnc?)
[00:09:56] <Encapsulation> I read that the free cam software wasn't very good, thats why I'm thinking about meshcam
[00:10:05] <Encapsulation> I heard it's easier to learn, works well, price is reasonable
[00:10:43] <Encapsulation> really when I start to consider tooling, clamps, vacuum, possible enclosure, table, dust, software
[00:10:51] <Encapsulation> the $3800 raptor isnt even an option
[00:10:54] <Encapsulation> its down to just those 3 machines
[00:11:11] <Encapsulation> I kind of like the idea of putting the raptor together myself
[00:11:18] <Encapsulation> and seeing how it all fits together and wiring it all up
[00:11:30] <Encapsulation> but I also don't like the idea of having to build an enclosure for it. Perhaps a pc case would work nicely
[00:11:44] <Encapsulation> the x6 and 6040 are turn key
[00:11:54] <Encapsulation> raptor is fully disassembled

[00:50:10] <pink_vampire> Encapsulation: did you order a machine?
[00:57:35] <sthns> hi there, how do i find out if my cnc is compatible with linuxcnc? is just the controler information needed (in my case "Siemens 840D SL" and "Heidenhain iTNC 640")?
[00:58:01] <malcom2073> sthns: most everything is compatible with linuxcnc, it replaces the control entirely
[00:58:21] <skunkworks> you would need to know what sort of input the amps take.
[00:58:31] <malcom2073> *with some work* heh
[00:58:36] <skunkworks> and what sort of feedback there is
[00:59:12] <sthns> okay, so it will take a bit of time, reading and talking
[01:02:14] <pink_vampire> sthns: by default your drivers should work with Step Direction commands to be able to work with linuxnc
[01:03:22] <sthns> yeah that should be the case. this is the machine in question btw: http://gies.se/uploads/images/130/DSC_6212_detail_f71b5515c33c094b7dc0874cd8baf2bdc7c4d447.png?1410773610

[01:05:31] <sthns> for nearly all individual uses benchtops are more practical
[01:06:10] <pink_vampire> yeah,, she is cute.. :)
[01:06:18] <sthns> this is in a kind of project with lots of woodwork involved in the rooms of an old foundry
[01:07:02] <pink_vampire> why do you want to use linuxcnc?

[01:07:22] <pink_vampire> what's wrong with the original controller?
[01:08:10] <sthns> that was a decision before my time, mostly because of idelogical reasons and a bit of troubles with the former electronics

[01:13:45] <pink_vampire> my machine (old pic)
[01:14:17] <malcom2073> pink_vampire: I'm just amazed you manage chip control
[01:14:18] <sthns> that is an orderly workingplace i am impressed - and a nice machine
[01:15:06] <pink_vampire> malcom2073: what do you mean??
[01:15:22] <malcom2073> pink_vampire: Lot of stuff around the machine for chips to get into
[01:15:32] <malcom2073> Plus wood floors, between the boards
[01:16:13] <pink_vampire> malcom2073: with 1000rpm spindle the chip don't fly that far...
[01:16:36] <malcom2073> Heh
[01:16:37] <pink_vampire> and vacuum cleaner.
[01:16:43] <malcom2073> I can't seem to get all my chips up no matter how hard I try :/

[01:18:13] <pink_vampire> but yeah.. it's start to become annoying, I'm thinking about wood tray or something foldable for collecting the chips
[01:18:47] <pink_vampire> the last part.. from the O2 steel, was razor sharp chips.
[01:18:49] <malcom2073> I really want an enclosure around my table
[01:18:57] <pink_vampire> fly alll over here..
[01:19:33] <pink_vampire> I'm thinking about up side down umbrella
[01:19:45] <malcom2073> Would catch the close-in stuff
[01:20:14] <pink_vampire> I don't want it permanent, it's a small house.
[01:20:16] <malcom2073> I'm thinking a bolt on enclosure, with magnets holding the lexan in place
[01:20:22] <malcom2073> For mine
[01:20:29] <malcom2073> but yeahenclosures make things seem bigger
[01:20:34] <pink_vampire> that nice idea.

[01:29:13] <Encapsulation> pink_vampire, not yet, sadly.
[01:29:57] <pink_vampire> why it is so complicated?
[01:31:10] <malcom2073> What's gonna be an absolute riot, is once Encapsulation gets a machine in house, and has to figure out software, and then has to figure out tooling
[01:31:22] <malcom2073> That'll lead to *months* of deliberations :P
[01:31:25] <Duc> most arent run by linuxcnc right?
[01:32:01] <Jymmm> pink_vampire: Are we talking nail removal? If so, then 30 degrees =)
[01:32:26] <Encapsulation> malcom2073, I've picked those already at least =D
[01:32:34] <Encapsulation> freecad, meshcam, linuxcnc
[01:32:47] <Encapsulation> and some chinese tools from amazon people report good results for my uses with
[01:34:33] <pink_vampire> Jymmm: I mean about the small V block that I want to make.
[01:37:06] <malcom2073> I think mine are 90
[01:38:36] <Jymmm> pink_vampire: Where the evil in that?! Eeeeeeesh
[01:40:51] <pink_vampire> I want to be able to hold 1/4" to 3/4" with them
[01:41:26] <pink_vampire> http://i.imgur.com/WZQYZ20.png
[01:41:43] <Encapsulation> pink_vampire, we all have needs
[01:42:05] <pink_vampire> the V is ok? or it's too small?
[01:42:18] <Encapsulation> looks good, but remember
[01:42:25] <Encapsulation> always get bigger than you think you will need
[01:43:06] <pink_vampire> I need it to make very small part
[01:43:23] <pink_vampire> that one http://i.imgur.com/zOUfWOw.png
[01:43:31] <pink_vampire> top to bottom 8.5mm
[01:43:39] <Encapsulation> that drawing has no dimensions
[01:43:42] <Encapsulation> ah I see
[01:43:46] <Encapsulation> 8.5mm...
[01:43:46] <pink_vampire> 8.2 with
[01:43:47] <Encapsulation> hm...
[01:44:05] <pink_vampire> the holes are 1.27mm diameter.
[01:44:31] <pink_vampire> the hole in the center need to be tapped for M2
[01:44:51] <pink_vampire> what do you think?
[01:45:20] <Encapsulation> it might work, but you'd better double check
[01:47:36] <Encapsulation> these fruit loops are incredible

[01:50:26] <Encapsulation> xD
[01:51:03] <pink_vampire> I'm cooking now quinoa with barley
[01:51:39] <pink_vampire> quinoa is the best thing ever!

[02:02:26] <pink_vampire> yes
[02:03:11] <pink_vampire> 4" Z axis travel with 1" tool length is actually 3" Z travel.
[02:04:00] <pink_vampire> also vacuum table

[02:24:06] <Encapsulation> thats true
[02:24:32] <Encapsulation> 2.7" part +1.5" tool +.5"spoilboard = 4.7" machine has 5.5" clearance 5.5" travel
[02:24:38] <Encapsulation> for x6 machine
[02:24:45] <pink_vampire> but I can't type it all.. but I can make a conversation with you if you want.
[02:25:04] <Encapsulation> ebay 6040 just 3.9" clearance 2.5" travel
[02:25:11] <Encapsulation> ok

[10:33:10] <XXCoder> hey miss0r
[10:33:20] <XXCoder> I replaced my car o2 sensor
[10:33:27] <XXCoder> it definitely improved
[10:33:37] <miss0r> I'm glad to hear :)
[10:33:38] <XXCoder> still minor idle issues, think thats from vacuum system
[10:34:01] <XXCoder> p0135 always come up, think fuse is broken too
[10:34:12] <XXCoder> have to look for it tomorrow lol
[10:34:13] <miss0r> Are you thinking the system is not completely air tight?
[10:34:25] <XXCoder> maybe, its bit hard to tell lol
[10:34:45] <miss0r> vacuums a bitch
[10:35:09] <XXCoder> yeah I once replaced all vacuum tubes in car before I got van
[10:35:16] <XXCoder> that fixed issues so hard.,
[10:35:16] <miss0r> i'm having some hearaches of my own here. This post processor won't write it self, apparently
[10:36:03] <miss0r> You should do that then. or atleast go through them and look for visible cracks
[10:36:21] <XXCoder> one of tubes is very nast7
[10:36:37] <XXCoder> its so nasty I could not complete nasty word ;)
[10:36:52] <XXCoder> anyway its behind the engine, near top, near EGR
[10:36:58] <miss0r> I thought you were trying to bring back l33t... al thou iirc 7 was T ;)
[10:37:01] <XXCoder> its common failure point apparently
[10:37:12] <XXCoder> nastt indeed lol
[10:39:12] <miss0r> That should be an easy fix then?
[10:39:26] <XXCoder> most tubes I think is very accessable
[10:39:28] <XXCoder> one isnt
[10:39:34] <XXCoder> the "nastt" one

[10:40:30] <XXCoder> the easily accessable ones seem to be in good condition. (older car everything was brittle and broke as I removed em)
[10:40:43] <archivist> sometimes you just have to take things to bits to fix
[10:40:50] <XXCoder> it was damned good luck that I managed to take pictures before I removed too much
[10:41:04] <miss0r> hehehe yeah

[10:42:43] <miss0r> I am soon to be fucked here. I just recieved an order for a support bar for a motorcycle, and my mill isn't up and running yet.... this post is driviing me mad
[10:43:00] <archivist> fun is customer getting stuck and bringing a kit in, can you put this back together?...
[10:43:25] <archivist> miss0r, write the code by hand
[10:43:38] <miss0r> archivist, I might need to soon enough
[10:43:51] <miss0r> but It would just be sweet to get this thing going
[10:45:43] <miss0r> Theres just too much unsupported/jitter in these posts, I need to sort out. I wish I could only find a simple 3-axis post with only the basics. I am realy only going to be using the controller for reading baisc G-code.. not all the canned cycles/other strange build-in stuff. just arcs and linear stuff.
[10:46:05] <miss0r> I have been looking for a VERY basic mastercam post to edit, but i've had no luck thus far
[10:46:17] <XXCoder> can always use dxf to gcode
[10:46:26] <XXCoder> then hand edit around it probably
[10:46:57] <miss0r> I guess - but I haven't ever realy found a good converter, that can do helix and ramps and stuff :)
[10:48:05] <miss0r> also, I do my CADs in mastercam, so it would be realy helpful for it to simply stop messing about and start working the way I want.
[10:48:27] <XXCoder> too bad that mastercam is so expensive

[10:49:48] <XXCoder> whoa
[10:49:50] <archivist> they probably already have something, huge profits being made
[10:49:52] <XXCoder> that is expensive
[10:50:13] <miss0r> That is what i'm thinking. This can't possibly be the first philips 432 they've written a post for!
[10:50:20] <archivist> there is a lot of overpricing in this world
[10:50:26] <XXCoder> probably cheaper to work with fusion or even buy mastercam itself
[10:50:36] <XXCoder> archivist: and rents is flying so hard. :(
[10:50:59] <XXCoder> I'm single, work fulltime with pretty decent wages, and I cant afford apartment.

[10:51:59] <XXCoder> there is always freecad
[10:52:05] <XXCoder> though its cam sucks
[10:52:08] <XXCoder> UI wise anyway
[10:52:47] <miss0r> freecad... free...
[10:52:49] * miss0r shudders
[10:52:57] <XXCoder> I love its cad functions
[10:53:01] <XXCoder> but cam just sucks
[10:53:08] <XXCoder> I could not make it work.
[10:53:20] <miss0r> The cam is was is what is causing issues here :)
[10:53:21] <XXCoder> be sure to get later version than 13, 13 sucks
[10:53:43] <XXCoder> indeed that is why I pointed out that cam suckjs
[10:53:58] <miss0r> I will need to write a post processor for that as well. and atleast with mastercam I have 'some' concept of what I am doing

[10:54:36] <miss0r> some - as in: not at all enough for anything, but more than null
[10:56:00] <XXCoder> dunno how good mastercam is lol but then its danged everywhere
[10:56:28] <XXCoder> I only used it to export gcode when I worked at internship so I dont know much behind that
[10:57:13] <miss0r> nor do I - but I can very easily create a workpeice, create tooling and export g-code - basically what I need.
[11:00:09] <XXCoder> cool
[11:01:02] <miss0r> it used to work wonders for my linuxcnc controller. but that is now, sadly, retired. and I am left with this '86 era controller that I need working soon

[11:43:54] <XXCoder> mass industry is quite dofferemt
[11:43:57] <XXCoder> different
[11:44:54] <codepython777> XXCoder: this is not produced in mass for sure

[11:46:02] <malcom2073> codepython777: So they might buy three years at once
[11:46:19] <archivist> codepython777, you are forgetting any setup charge of a machine
[11:46:21] <XXCoder> yeah larger production is cheaper
[11:46:23] <malcom2073> Or, they might get it from a much cheaper cnc shop
[11:46:59] <XXCoder> theres one job at shop I work at that has job only run 2 times each, but 1,500 parts a time
[11:47:02] <malcom2073> Typically two pieces will be trivially more expensive than one if setup time is minimal
[11:47:17] <XXCoder> those parts has so many steps. so many.
[11:47:30] <archivist> find tools, bolt on a vice, cart some bar to chunks, mount, mess about doing some gcode/cam etc

[11:50:03] <_methods> google drive
[11:50:25] <malcom2073> codepython777: Also, if you've only asked one shop, ask 2-3. Possibly they don't *want* to do it, so they quoted you high, but $100 seems cheap for a single part
[11:50:37] <witnit> http://www.tinyupload.com/
[11:50:39] <witnit> works
[11:50:59] <_methods> is the part hardened, coated, painted?
[11:51:04] <_methods> or just raw metal?
[11:51:11] <archivist> or plastic
[11:51:13] <_methods> tight tolerances?

[11:52:06] <codepython777> http://dpaste.com/0QSE3F2

[11:54:35] <malcom2073> live tooling and multi-axis milling attachments
[11:54:43] <_methods> you just need to take it to the right shop

[11:55:00] <archivist> rob_h, has that sort of machine
[11:55:22] <codepython777> which country is he in?
[11:55:42] <codepython777> even if its an easy job for an expensive machine - $9/pair? How does that work?
[11:56:07] <XXCoder> $100 probably because they have to subcontract if they dont have that expensive machine
[11:56:08] <archivist> a plain image
[11:56:12] <malcom2073> An expensive machine can pop thouse out a couple per minute
[11:56:15] <_methods> yeah
[11:56:15] <malcom2073> so in qty 1000, cheaper
[11:56:28] <codepython777> malcom2073: these machines can tap automatically as well?

[11:56:40] <codepython777> i see
[11:56:46] <malcom2073> And do both sides with back tooling
[11:56:56] <archivist> a 5 axis with auto toolchanger as well
[11:57:03] <_methods> 5 axis is overkill for that
[11:57:14] <_methods> any c or y axis lathe will do that part easily
[11:57:15] <codepython777> how much do these cost? 100k or 1M or can you buy it < 100k?
[11:57:19] <archivist> I cant see it yet

[12:10:08] <codepython777> rob_h: how much does a part like that cost me if i want 25 of them from you? :)
[12:10:53] <rob_h> lol how big is it... whats it made from haha is it 1mm big or 50mm
[12:11:16] <_methods> looks like it's 24mm long
[12:11:23] <_methods> assuming scale of stp was correct on import
[12:11:42] <_methods> and 15.4mm max OD
[12:11:58] <_methods> he said it was alum
[12:12:05] <_methods> so i'm assuming 6061
[12:12:47] <_methods> so drill and tap for tapped holes, drill for center hole and boring bar, and end mill for hex head
[12:12:58] <_methods> say 7 tools to setup and bar feeder
[12:13:28] <_methods> 2 hour setup time if nothing is in the turret
[12:13:46] <_methods> most shops you'll be paying $300 just for the setup time alone
[12:14:33] <rob_h> yea prob with imports no drawings is no tolerances also
[12:14:35] <_methods> around 2 min cycle time depending on how fast the turret is
[12:14:52] <_methods> yeah no tolerances so hard to say without that complication added
[12:15:01] <rob_h> or thread depths
[12:15:13] <witnit> looks like an easy job
[12:15:28] <_methods> it's not bad but for 25........
[12:15:33] <witnit> a print would be nice
[12:15:36] <_methods> 1000 would be better
[12:15:43] <witnit> or maybe 50,000
[12:15:46] <witnit> imo
[12:16:20] <_methods> i think the $100/pc he got quoted was extremely high
[12:16:45] <_methods> i'd think $25/pc wouldn't be too bad even for a lathe/mill setup
[12:17:03] <_methods> but still way outside of his target of $8/set
[12:17:11] <_methods> i'm assuming a set is 2 parts
[12:17:17] <_methods> so you need them to be $4/pc
[12:17:41] <witnit> codepython777: what is your estimated annual usage on this part?
[12:17:57] <_methods> in order to get in the $4/pc range you would need much larger order
[12:18:04] <codepython777> I've an order of 25 - first lot - after that depends on how many i get - no idea
[12:18:11] <witnit> (my personal favorite way to quote a job is to know the EAU)
[12:19:38] <archivist> drawings with tolerances for proper quotes
[12:19:52] <_methods> yes all we can do is give you guesses without real prints
[12:19:55] <witnit> The type of shop best suited for this would probably be a swiss screw machine, most would be well tooled for such an operation
[12:20:42] <archivist> pay me enough to retrofit mine to cnc :)
[12:20:48] <_methods> hehe
[12:21:02] <_methods> 25*8=$200
[12:21:03] <witnit> codepython777: if you give very liberal tolerances you will get a much better quote
[12:21:14] <_methods> what can you do with $200 archivist lol
[12:21:21] <archivist> not a lot
[12:21:29] <_methods> heheh
[12:21:32] <_methods> damn
[12:21:50] <archivist> just about feed myself
[12:21:57] <_methods> groceries for the week lol
[12:22:12] <_methods> live axis legs to walk you to the store
[12:22:26] <archivist> actually food for me is down to about 15$
[12:22:48] <_methods> so that leaves $185 for beer
[12:23:11] <archivist> currently no beer for at least a couple of years

[12:26:10] <rob_h> problem is, start using power tooled lathes or multi spinel turret lathe, you on something costs easy 350k so hour rate on that is going to be crazy thats if its fairly new if it was a simple 2 axis turn it part it off job then yea cheap as chips any one can make
[12:26:48] <_methods> that's why i said $300/hour setup 2 hours
[12:26:50] <rob_h> like you take a part on a standard 3axis VMC.. then have a part that needs a 5axis machine big jump in price
[12:26:52] <_methods> 1 hour programming
[12:26:53] <archivist> or use more than one type of machine
[12:27:05] <_methods> so about $900 for initial run just in setup and programming

[12:28:29] <_methods> at a shop with just 3 axis machines and normal lathes it would be 2 setups in the mill
[12:28:41] <_methods> 1 for cross drill and tap and 1 setup for hex
[12:29:06] <_methods> and the tapped holes have to be clocked to the hex head
[12:29:12] <archivist> or a tapping head in a pillar drill

[12:35:04] <witnit> live tooling would be handy for the hex
[12:35:18] <witnit> everything else is pretty simple
[12:36:15] <archivist> the contra rotation hex cut is something to watch
[12:36:52] <witnit> contra?
[12:39:13] <archivist> https://www.youtube.com/watch?v=ZBDxveTBQLE
[12:40:05] <witnit> yeah those been around awhile
[12:41:17] <_methods> wtf cool
[12:41:20] <_methods> never seen that before
[12:41:31] <witnit> I think they were originally just a geared in shaft to spindle with number of cutters per wheel to genrate the polys
[12:41:59] <_methods> interesting
[12:42:02] <witnit> so 1 cutter makes two flats, 2 cutters make a square, 3 a hex
[12:42:22] <_methods> it's like ghetto live tooling
[12:42:27] <witnit> there is also the rotary slotting attachement
[12:42:37] <witnit> yeah but super fast ghetto tooling
[12:42:45] <witnit> and long life
[12:43:17] <witnit> imagine putting a screwdriver slot in the end of a part while the part is being rotated
[12:43:42] <archivist> _methods, look at the machining lines on your 1/2 socket set, often the square made that way
[12:44:04] <_methods> oh yah
[12:46:44] <archivist> https://www.youtube.com/watch?v=oGq-9NNmr3o&feature=player_embedded
[12:49:02] <gregcnc> I saw an polygon attachment for a manual lathe one Ebay once

[12:49:24] <_methods> cool video explaining it
[12:51:16] <witnit> oh this one is neat, first a geometric pop-open diehead comes in, then a thread chasing attachment hits it from the cross slide https://youtu.be/Gly0_mvzK5g?t=36
[12:51:22] <witnit> all mechanical :)
[12:52:24] <witnit> oh lucky buggars even have the automatic barloader
[12:52:38] <_methods> that thing looks like a setup nightmare
[12:52:45] <witnit> they arent too bad
[12:52:55] <witnit> but you gotta take the learning curve
[12:53:04] <gregcnc> the die head roughs the thread?
[12:53:08] <witnit> no
[12:53:15] <witnit> they are cutting two different threads on the part
[12:53:33] <gregcnc> that's what I figured, but I couldn't see it on the part
[12:54:11] <witnit> I assume its just a pipe thread coming from the geometric and then a straight thread on the spindle side
[12:54:30] <witnit> or just two different straights
[12:54:43] <witnit> possibly L and R handed

[13:08:43] <witnit> double indexer on the turret and the swing in stock stop to lower cycle time

[13:31:49] <FinboySlick> witnit: Depends on where your costs are. Hiring smart people is often more difficult than buying smart machines.
[13:32:01] <archivist> noobs think the setup time matters more than the cycle time

[13:40:52] <witnit> FinboySlick: that may be so, but the bottom line is, in a long production run, a cnc cannot compete with a screw machine and cold header shop
[13:43:40] <witnit> whats your cycle time again? https://youtu.be/994kHYpCZVY :)
[13:43:56] <gregcnc> cnc screw machines do well
[13:44:26] <witnit> they are not affordable for many jobs due to shop rate required to pay off the machine
[13:44:39] <witnit> they really have to be complex high production
[13:45:04] <gregcnc> not really I know a shop that runs fairly simple parts and has at least 6
[13:45:05] <witnit> almost like high production swiss type work
[13:45:16] <witnit> what do you mean fairly simple?
[13:45:16] <Jymmm> Is step/dir pwm, or something else?
[13:45:35] <gregcnc> something else
[13:45:58] <Jymmm> gregcnc: Know what it is or called?
[13:46:07] <gregcnc> witnit you probably use them every day, but I'm not going to say
[13:46:25] <Jymmm> swiss chop sticks!
[13:46:38] <gregcnc> i only know it as step/ dir
[13:47:03] <Jymmm> gregcnc: Ok, thanks. I dont think it's grey code, but something else.
[13:47:04] <gregcnc> PWM is like ±10V analog, but uses a PWM signal
[13:47:20] <gregcnc> PWM Frequency
[13:47:49] <gregcnc> The AMC manuals talk about it because they make both
[13:49:46] <Jymmm> I"m looking to do something like this (excuse the flood):

[13:49:52] <Jymmm> 010
[13:49:52] <Jymmm> 101
[13:49:54] <Jymmm> 111
[13:50:25] <Jymmm> But *I* dont recognize if that is alread a set schema or if I'm making it up new.
[13:50:25] <archivist> gray code one bit change at a time
[13:50:54] <Jymmm> archivist: Right, and in the above that's not the cae. I'm just not aware of OTHER codes
[13:51:20] <archivist> yours looks a bit erm not right
[13:52:17] <Jymmm> Yeah it's NOT grey code, it's (basically) an increase in bits... sorta a pseudo pwm of sorts.
[13:52:21] <gregcnc> that's what I was thinking, but I dont' know what you're doing. I;ll have something like that with a lookup table for the ATC inthe lathe with three switches

[14:10:49] <archivist> you know tables take up less space than equivalent code usually
[14:31:01] <Jymmm> a lot = 20-50
[14:33:22] <archivist> with a table you have one bit of small code and n entries, code to bit bang a port is larger than a table entry, you do the maths
[14:36:57] <Jymmm> It's not just the existance of tales, but the mundane process of crating them. And will eventually be adding even more. Where code may be larger, would allow flexability.

[14:47:46] <Jymmm> I have a couple of rotary encoders I'm going to use to make adjustments until I get what I want.
[14:49:49] <Jymmm> But it's like when milling a square with radius corners, and the tool has to slow down when it starts the arc, and speed up coming out of it. It's THAt where I'm a bit clueless on.
[14:51:19] <Jymmm> I'm thinking I need to view this (mentally) as a waveform, then bitbang that out.

[16:38:29] <Encapsulation> you dont fix it yourself?
[16:38:30] <Encapsulation> =D
[16:38:36] <Encapsulation> I dont trust mechanics
[16:38:41] <Loetmichel2> i should have
[16:38:51] <Encapsulation> and if hes "guess and check" mechanic
[16:38:57] <Encapsulation> maybe time for a new mechanic xD
[16:39:26] <Encapsulation> I take my vehicle to the dealer to find out whats wrong
[16:39:28] <Encapsulation> for $100
[16:39:32] <Encapsulation> then I fix it myself and save thousands
[16:39:36] <Loetmichel2> but as the engine has blown every gasket and seal it had ( crank case vent was clogged) i didnt want to get THAT dirty. so i now have paid €4k and STILL have no working car...
[16:39:54] <Encapsulation> thats unacceptable for sure
[16:40:25] <Loetmichel2> especially because the car is 13 years old and worth about €1800
[16:40:30] <Encapsulation> @_@
[16:41:10] <Encapsulation> if you're paying more than a car payment each month to fix your car... time to buy a new car maybe
[16:41:23] <Encapsulation> or a running used one
[16:41:58] <Loetmichel2> btw: before the "repair" it was working flawlessly... only throwing about 5 liters oil in 500km on the street

[21:00:00] <t12> safer i imagine

[21:09:31] <SpeedEvil> what?
[21:09:42] <CaptHindsight> keep shuttling fuel out to the International Gas Station
[21:10:01] <SpeedEvil> Well, yes, that too
[21:10:42] <SpeedEvil> If you launch a F9 first stage with no second, retank it in orbit, and then do the same with a second stage, your payload capability is _stupid_

[21:11:39] <CaptHindsight> the Ruskies could probably do it better
[21:12:02] <CaptHindsight> it's basically 2 aluminum tanks in a tube
[21:12:53] <unfy> it probably won't work this way for a while - but lets try it this way. the cost to put a comms satelite into orbit becomes cheaper. thus, they can provide phone service cheaper. or if you believe in the gov't doing all this - your tax dollar goes further.
[21:13:50] <CaptHindsight> my calls are already at a flat monthly rate and overpriced, based on price fixing vs free market
[21:14:28] <CaptHindsight> and they aren't over satellites

[21:18:26] <XXCoder> only way to get it cheaper is less weight
[21:18:54] <XXCoder> unless we find better way to get to space, it will always be expensive per pound.
[21:19:01] <enleth> unfy: all normal service is over the wire or terrestial microwave
[21:19:15] <SpeedEvil> In principle, $100/kg is achievable with reusable conventional launch

[22:24:55] <Jymmm> On one, I cut off the stud and attempted to drill it out to replace with a grade 8 bolt instead. but the pressed in part at minimum is 1/2" and just trying to drill it out has snapped a coule of bits so far.
[22:25:19] <Jymmm> 1/2" wide that is
[22:25:45] <SpeedEvil> cut it off leaving the bearing?
[22:25:59] <Jymmm> Else the inner part just spins, even when clamped with vise-grips
[22:26:16] <Jymmm> SpeedEvil: I cut it off just at the base of the threads
[22:26:42] <Jymmm> it was as close to the pressed in part as I could get to with a 4" angle grinder.

[23:08:51] <SpeedEvil> The shaft is not well attached - spins - compared to the ball races?
[23:09:43] <Jymmm> the "shaft" is pressed in, and is loose so it just spins, thus the channel locks you see in an attmpt to hold it
[23:10:30] <SpeedEvil> Do you have a welder?
[23:10:41] <Jymmm> sadly, no.
[23:11:02] <SpeedEvil> Is there a stub on the shaft with a good thread?
[23:11:48] <Jymmm> Except for the one caster where I cut off the threaded part of the shaft they are all there as seen in the left-most pic
[23:12:09] <SpeedEvil> Oh - just slightly bendy
[23:12:41] <SpeedEvil> You can cut off the bendy bit of the shaft, and then thread on two nuts, and crank them against each other to get a nice lock.
[23:12:42] <Jymmm> Well, slightly bendy, extends to 2" bended wheel
[23:13:11] <SpeedEvil> Now clamp one in the vice, and use that firmly attached to - with very heavy pressure slowly - drill out from the base
[23:13:17] <Jymmm> which extends to 1000lb rack falling over =)
[23:13:47] <Jymmm> Ok, I see what you're saying, vise the attached nuts
[23:14:26] <Jymmm> Actually, may NUT need two nuts, as they would be upside down
[23:14:30] <Jymmm> NOT*
[23:14:47] <SpeedEvil> you don't want to spin the shaft in the top 'nut' - as that may 'clamp' down on the balls and damage the bearing
[23:15:14] -!- BeachBumPete has quit [Quit: I'm Outta here!!]
[23:15:29] <CaptHindsight> XXCoder: 32 Trillion could pay for lots of rocket programs :)
[23:15:35] <Jymmm> Right, but I think the drill bit would be going in the same direction as "tightening" the nut
[23:15:50] <SpeedEvil> yeah - but if you're working against the clamped nuts - it's not an issue
[23:17:04] <Jymmm> I hear ya. Now, what the hell do I do about this monster pressed fitting?1 I'm already at 1/2" drill bit and STILL not big enough it seems.
[23:17:56] <CaptHindsight> gas wrench
[23:18:01] <Jymmm> and it's gotta be either heat treated or work-hardened, as it's a mofo to drill, even starting at 1/8" and working my way up
[23:18:34] <SpeedEvil> Or stick
[23:18:46] <Jymmm> hmmm???
[23:19:00] <SpeedEvil> and tack to the bottom, then unscrew the 'nut' on top after tidying the thread
[23:19:05] <CaptHindsight> http://pad1.whstatic.com/images/d/db/Cutting25_132.jpg
[23:19:30] <SpeedEvil> stick may be better - you can't heat the bottom too much, it's got a ball race in
[23:19:31] <Jymmm> CaptHindsight: lol, only propane torch =(
[23:19:42] <Jymmm> stick???
[23:19:51] <SpeedEvil> stick welding
[23:19:54] <Jymmm> ah
[23:21:50] <Jymmm> I just keep thinking there should be something OTERH than a drillbit I should be using, like a tapered abrasive bit, or whatever, but since everything is recessed, it's a bitch to get anythign in there without damaging other parts.
[23:22:44] <Jymmm> no edm availabel either btw ;)
[23:22:54] <CaptHindsight> have a grinder and some stones?

[23:24:37] <Jymmm> CaptHindsight: would that work in a drillpress?
[23:24:44] <SpeedEvil> Jymmm: it's easy to grind it off, but not in that location
[23:24:49] <CaptHindsight> a fast one
[23:25:06] <Jymmm> SpeedEvil: tell me about it =)
[23:25:17] <SpeedEvil> Err - nvm
[23:25:36] <Jymmm> CaptHindsight: is that bit THAT agressive? and come in 5/8" ?
[23:25:36] <SpeedEvil> On reflection - take above 'two nuts' suggestion - and try to unscrew the big 'nut' at the top
[23:25:52] <SpeedEvil> After lubricating the shaft just above the large nut
[23:26:12] <Jymmm> SpeedEvil: It's all pressed, no nuts anywhere.
[23:26:12] <SpeedEvil> perhaps after applying gentle heat to the whole thing
[23:26:35] <Jymmm> SpeedEvil: think like a giant funky ass treaded rivet
[23:26:40] <SpeedEvil> Jymmm: It looks to me like the shaft going through the whole thing is threaded on top, and teh big hex nut is on top
[23:27:35] <SpeedEvil> they thread the nut onto the threaded shaft, put the balls in, put the bottom cage on, and peen the end of the shaft
[23:27:35] <gregcnc> tap something for that thread put it in the mill vise and drill it with a carbide tipped concrete drill
[23:27:53] <SpeedEvil> ^resharpened
[23:28:13] <Jymmm> SpeedEvil: That 2" or so hex plate thing is "suppose" to be able to thread the caster on to the leg, but the pressed part is too loose to even use it for that, with ZERO load on the rack
[23:28:29] <CaptHindsight> cutting wheel on the grinder and go right through the blue
[23:28:47] <SpeedEvil> CaptHindsight: there is a bearing there
[23:29:02] <SpeedEvil> CaptHindsight: there is a circular race around the top and bottom of the plate bearing the wheel
[23:29:04] <CaptHindsight> not after the wheel cuts through :)
[23:29:16] <Jymmm> lol, bastard =)
[23:29:32] <SpeedEvil> Well - yes - in principle you could remake it - but I'm guessing that Jymmm does not have a lathe suitable to make a replacement
[23:29:52] <Jymmm> give that man a prize!
[23:29:55] <CaptHindsight> Jymmm: please provide us a list of your tools
[23:30:08] <CaptHindsight> we will deliberate and come up with a plan
[23:30:27] -!- rob_h has quit [Ping timeout: 260 seconds]
[23:30:42] <gregcnc> if you thread that stud into a plate or block it should tighten itself when you drill from the back. unless you have sticks and rocks to work with
[23:31:05] <Jymmm> drill presses, 4" angle grinder, bench grinder, band saw
[23:31:31] <Jymmm> gregcnc: the thing is, there is nothing to grip on the back side of that threaded shaft to tighten
[23:31:51] <SpeedEvil> Jymmm: you jam two nuts onto the shaft
[23:32:08] <SpeedEvil> Jymmm: crank one clockwise, the other anticlockwise, so as to grab the shaft firmly
[23:32:19] <Jymmm> SpeedEvil: Yes, but not for what gregcnc was suggesting
[23:32:28] <gregcnc> you don't have to tighten, let it tighten itself as you drill
[23:32:42] <SpeedEvil> gregcnc: which will pinch the bearings
[23:32:56] <gregcnc> there si a step on that shaft
[23:33:00] <Jymmm> I am going to do the two nuts opposing each other thing.
[23:33:16] <CaptHindsight> Trump and Cruz
[23:33:26] <gregcnc> how to they peen it if it pinches the bearings?
[23:33:43] <Jymmm> Instead of potentially snapping a few more drillbits, is there something else I should be using ?
[23:33:56] <SpeedEvil> Jymmm: die grinder
[23:34:06] <SpeedEvil> gregcnc: hmm
[23:34:24] <Jymmm> SpeedEvil: I dont have a compressor or die grinder, or do you mean just the tapered bit?
[23:36:16] <SpeedEvil> ti won't really work with a drill press alas
[23:36:53] <Jymmm> figured. and I'd probably empty my nitrogen tank before getting thru the first one too
[23:37:23] <CaptHindsight> liquid nitrogen and a sharp blow
[23:37:47] <Jymmm> CaptHindsight: Shit, lets do this in one shot.. LOX
