Back
[00:00:48] <Wolf_> damn, $150/mo
[00:04:00] <CaptHindsight> do they have surgical tools?
[00:04:40] <pink_vampire> way?
[00:04:46] <CaptHindsight> thinks of the savings for DIY
[00:05:31] <pink_vampire> omg
[00:06:56] <pink_vampire> the closest to my location is pa
[00:06:59] <pink_vampire> :(
[00:07:13] <Wolf_> DC one is almost not close to me
[00:09:47] <pink_vampire> but we have our own hacker space :)
[00:11:30] <pink_vampire> Wolf_: how do you cut stock?
[00:11:52] <Wolf_> bandsaw or cold saw or plasma
[00:12:40] <Wolf_> oh, pcb stock?
[00:12:45] <pink_vampire> no
[00:12:48] <pink_vampire> metal
[00:13:47] <Wolf_> have 3 porta bands, a 9x20 wilton horizontal band, 14” dry cut saw
[00:16:07] <pink_vampire> i have one portable band saw - i don't like the finish cut, and now i got cute and old power hacksaw
[00:18:14] <pink_vampire> i did few cuts on it and I'm getting vary nice and smooth cuts, the only thing that i don't like about it, is the vise
[00:18:58] <Wolf_> yeah, porta bands are kinda rough on end finish, usually wrong tooth count for material though, mine do pretty well
[00:19:24] <pink_vampire> i'm using a metal blade
[00:19:34] <Wolf_> dry cut leaves nice finish but its too damn loud lol
[00:19:52] <pink_vampire> but the cut is not 100% flat
[00:20:32] <Wolf_> yeah, hand held like to walk
[00:20:54] <pink_vampire> i wanted to buy the dewalt 14in cold cut saw, but the noise of the cold cut make me go with the power hacksaw
[00:21:15] <pink_vampire> it about 55 db
[00:21:56] <pink_vampire> or less, i know i have some washer and boshing that need to be replaced
[00:22:35] <Wolf_> I have the milwaukee version, for like 12yrs now, its loud and they aren’t nice to use with some things, had it rip stock out of the vice before
[00:23:53] <pink_vampire> what is the smallest stock that you can cut?
[00:24:54] <Wolf_> hmm, done 1/8
[00:24:58] <Wolf_> x 6”
[00:25:22] <Wolf_> but thats one of the pieces I have had pulled out of the vice and wrecked a blade
[00:31:17] <pink_vampire> i mean you can split 1/2" stock in half/
[00:31:19] <pink_vampire> ?
[00:32:35] <Wolf_> like cutting a 1/2” in to two 3/16”
[00:33:19] <Wolf_> no, I wouldnt try it…
[00:35:00] <pink_vampire> but it's important to be able to slice stuff
[00:35:37] <Wolf_> dry cut/cold saw is the wrong tool for that job if you value life and fingers
[00:37:42] <pink_vampire> i know
[00:38:21] <pink_vampire> this is way i end up with the power hacksaw
[00:41:14] <Wolf_> portaband in a stand and a rip fence would work good for that though
[00:41:35] <Wolf_> http://www.swagoffroad.com/SWAG-Portaband-Tables-Accessories_c_35.html
[00:45:40] <pink_vampire> http://www.swagoffroad.com/SWAG-V10-Portaband-Table-_p_64.html
[00:45:48] <pink_vampire> this is the one i have
[00:46:42] <Wolf_> harbor freight saw?
[00:48:15] <pink_vampire> yes,
[00:48:37] <pink_vampire> it's work, but the cuts not flat
[00:49:14] <pink_vampire> i have to remove about 1/16" on the mill to make the cut flat
[00:50:01] <Wolf_> thats somewhat normal, need to post process to get the tooth rake marks off
[00:51:26] <pink_vampire> but with the power hacksaw the finish is very nice, just a touch up on the mill, and it's fine
[00:52:42] <pink_vampire> 10-15 thou, and it's flat
[00:54:19] <Wolf_> yeah, thats about the same as my horizontal saw...
[00:55:11] <Wolf_> but then again its probably 5-600lbs
[00:55:31] <pink_vampire> 5-600?
[00:55:51] <Wolf_> 500-600+ lbs
[00:55:55] <Wolf_> its a big saw
[00:57:48] <Wolf_> blade type helps some as well,
http://a.co/aSxYMr9 or
http://a.co/dh6cb0K is what I keep in it
[01:01:24] <Wolf_> my milwaukee 2729 gets 10/14 blades if I remember right
[01:02:37] <pink_vampire> https://www.youtube.com/watch?v=beUOHXsUi6M
[01:03:05] <pink_vampire> i have one that look identical to this one ^
[01:03:11] <Wolf_> cool
[01:03:44] <pink_vampire> the blade is regular 12"
[01:07:19] <Wolf_> what my saw looks like lol
http://www.collierequipment.com/Liquidations/Oct_2013/Pics/Shop/00340.JPG
[01:07:30] <Wolf_> just, not that messed up
[01:08:29] <pink_vampire> i can't put something like that in my home
[01:10:03] <Wolf_> lol yeah
[01:10:25] <Wolf_> takes up some room and little big for most home shops
[01:11:21] <pink_vampire> why do you have it and a mini mill?
[01:12:32] <Wolf_> because primary work in my shop is commercial truck upfitting and welding/fabrication
[01:12:39] <Wolf_> not machining… yet
[01:33:33] <Wolf_> stuff like this
http://i.imgur.com/gzw7p90.jpg http://i.imgur.com/wSkwsNi.jpg
[01:39:13] <archivist> not enough space to build items error
[01:49:36] <pink_vampire> archivist: what do you mean??
[01:50:12] <Wolf_> probably the fact that I build stuff thats bigger then my garage bay lol
[01:50:59] <archivist> I understand the problem...
http://www.collection.archivist.info/searchv13.php?searchstr=glass+trolley
[01:51:52] <Wolf_> lol
[01:51:55] <Wolf_> http://i.imgur.com/ovIll6R.jpg
[01:53:57] <archivist> I made parts in the back garden, joined together near the bench, up ended to bring out the front and finish on the drive
[01:55:32] <pink_vampire> i'm focus on the small stuff
[01:56:26] <archivist> when someone offers money to make something.... just do it
[01:57:15] <Wolf_> most things won’t fit in the current shop
http://i.imgur.com/tvkbXBc.jpg http://i.imgur.com/DgReOwR.jpg
[01:57:39] <pink_vampire> same problem here
[01:58:11] <Wolf_> http://i.imgur.com/jlgAU08.jpg
[01:58:28] <Wolf_> my truck fits, but only half of it at a time
[02:04:23] <pink_vampire> omggggggggg
[02:04:45] <pink_vampire> tsop everything, and start clean it
[02:04:50] <pink_vampire> stop
[02:05:41] <Wolf_> for my shop, that doesnt matter, truck is 3 feet longer then the shop bay
[02:06:03] <archivist> one cannot, because run out of "away" to put stuff
[02:06:46] <XXCoder> happy snowy day
[02:07:28] <XXCoder> archivist: even if $1 to make very complex part? ;)
[02:08:56] <Wolf_> keep the snow, had enough last year
http://i.imgur.com/8sk1Aa8.jpg
[02:10:12] <XXCoder> it never get that bad here
[02:10:37] <Wolf_> and the FML moment from last year
http://i.imgur.com/DavcHSw.jpg
[02:10:51] <XXCoder> lol
[02:11:43] <Wolf_> truck was stuck in the driveway next door for 24 hrs
http://i.imgur.com/EcCznIL.jpg
[02:12:07] <XXCoder> so thats what you call light snow eh ;)
[02:12:30] <Wolf_> yeah…
http://i.imgur.com/wYaaVy7.jpg lol
[02:12:38] <pink_vampire> Wolf_: where are you located?
[02:12:46] <Wolf_> Maryland
[02:30:29] <Deejay> moin
[02:34:46] <trentster> hey all, I am busy with a new machine build, got a good deal on a bunch of 80x80 extrusion and wondering if anyone would like to critique the design before I start cutting the sections?
[02:38:17] <Wolf_> lets see it
[02:38:22] <archivist> pics or it didnt happen
[02:39:43] <XXCoder> pics
https://imgur.com/gallery/JjpLL
[02:40:03] <XXCoder> no see no critique
[02:40:05] <trentster> Here ya go:
https://sli.mg/ZiK5el
[02:40:42] <XXCoder> uh screws is tiny
[02:40:54] <Wolf_> ^
[02:40:57] <Wolf_> :D
[02:40:57] <XXCoder> unless you mean it to take entire length but just symbolize locations of those
[02:41:12] <trentster> lol, yeah its just for the mockup, to get the right height for mounts etc, real screws are correct length.
[02:41:18] <trentster> just done have them in cad
[02:42:21] <XXCoder> can Z assembly with tool reach bottom? (with bed included)
[02:42:29] <Wolf_> z axis travel looks long
[02:42:34] <trentster> I only have 80x80 beams, so I doubled up on them for the gantry and the sides(1 on top of the other)
[02:42:46] <XXCoder> reprap style sensor location
[02:42:46] <trentster> I will join them with brackets and t-nuts
[02:43:01] <XXCoder> if it fails to detect it'll sucuide
[02:43:25] <Wolf_> also don’t know about the gantry rails, might get twist
[02:43:43] <trentster> XXCoder: yes, the linear stage I have has 190mm of travel, which means in theory I could drill into the table beams with it if I wanted ;-)
[02:43:55] <XXCoder> ok
[02:44:03] <trentster> Wolf_: twist because they are not one piece extrusion?
[02:44:14] <XXCoder> you might want to move sensor so z assembly dont smash into it if y sensor fails
[02:44:47] <trentster> XXCoder: look at the rails on the gantry, not long enough to reach the sensor
[02:44:56] <Wolf_> longer Z = more leverage on the gantry. Twisting I’m talking about is the single linear rails that the gantry attaches to
[02:44:59] <trentster> there will be stop block at the end.
[02:45:05] <XXCoder> ahh ok
[02:47:11] <trentster> Wolf the gantry has 2 rails, each rail is spaced 120mm apart, is that too much?
[02:47:25] <trentster> Wolf_: ?
[02:47:44] <archivist> carriages you mean
[02:47:46] <Wolf_> not that, the ones that let the gantry travel the table length
[02:48:38] <trentster> right, (I call that X) you are saying they may be too far apart, they will be driven with dual ballscrews and motors
[02:49:25] <trentster> They are currently 1Metre apart
[02:50:14] <Wolf_> might work… router tables aren’t my thing though
[02:51:10] <trentster> hmmm…now you have put the fear of god in me :P
[02:51:56] <Wolf_> lol I didn’t know there was a screw on the other side
[02:52:30] <trentster> did you think I was driving it on 1 side only hah!
[02:53:33] <Wolf_> ya never know around here
[02:53:57] <archivist> plenty of crazies seen on the interwebs
[02:54:32] <archivist> you learn most actually making the thing
[02:54:46] <archivist> and then rectifying the faults
[02:55:06] <Wolf_> i’m still trying to figure out how I’m going to move the gantry on the plasma table I want to build
[02:55:36] <trentster> archivist: yes agreed, altho a smart person attempts to learn from the wisdom of others before he wastes material
[02:56:06] <trentster> *unless he has a big material budget for do-overs
[02:56:10] <Wolf_> by move, I mean gear rack, belts, chain, cabes…
[02:56:16] <Wolf_> cables *
[02:56:43] <trentster> Wolf_: from what ive read for plasma tables rack and pinion are best
[02:57:18] <archivist> there are some bugs you only learn when you get a problem
[02:57:54] <Wolf_> yeah, gear rack is also $$$ with the size of table I want to do
[02:58:06] <archivist> I built mine, it had poor rigidity, not enough working height, friction etc
[02:59:00] <archivist> and being built from available stuff, had no drawings
[02:59:51] <Wolf_> I may do rack and pinion to move the Z side to side, thats only 6 foot (1.8m)
[03:00:03] <trentster> Wolf_: If you keep an eye out on ebay, you can pick up deals. I bought 2 x 3M lengths of precision machined 52" gear rack for $30
[03:00:39] <trentster> I had no use for it but at the price could not help myself, its sitting in the shed ;-)
[03:01:31] <Wolf_> I’m thinking 6 foot x 8 foot cutting area
[03:02:02] <trentster> my brain works in metric lol
[03:02:29] <Wolf_> 1.82m x 2.43m
[03:02:53] <trentster> yeah, thats a respectable size
[03:03:10] <XXCoder> nice
[03:03:45] <trentster> you guys think it would be beneficial to fill extrusion centre hollows with sand and epoxy it in. I thought this would be a great aid for resonance dampening
[03:11:10] <archivist> best to find actual bending and stiffen with webs
[03:12:51] <archivist> eg I look at the gantry beam and thing with cutter in the middle you can get a cutting force derived bend
[03:13:01] <archivist> thing/think
[03:13:10] <pink_vampire> any computer numerical control solution for that problem?
http://makemeupmarie.com/wp-content/uploads/2015/04/screen-shot-2015-04-14-at-11-49-07.png?w=300
[03:14:14] <archivist> if you need that much make up, get a new face
[03:15:06] <pink_vampire> archivist: it's the eyeliner #1problem
[03:15:41] <archivist> often over done to the fugly stage, less is better
[03:17:57] <pink_vampire> https://www.youtube.com/watch?v=_ilabfMP82g
[03:18:54] <pink_vampire> archivist: ^
[03:20:09] <trentster> Anyone know WTH kind of motor this is? - it came with the used linear stage I bought?
http://sli.mg/XOXTv0
[03:20:09] <archivist> I cannot watch yt on this browser any more
[03:21:01] <Wolf_> looks electric
[03:21:10] <archivist> how many wires to the motor and how many from the encoder
[03:21:26] <pink_vampire> Wolf_: LOLLL
[03:21:36] <Wolf_> :D
[03:21:44] <archivist> is it free to rotate(magnetic steps or not)
[03:23:18] <trentster> 3 wires to the top part (encoder I presume), the motor I can not tell its wrapped in a metal sheath, but it looks like its more than 8
[03:23:41] <trentster> archivist: no, it has steps when it rotates like a stepper
[03:24:40] <archivist> 8 is comon for bipolar stepper
[03:25:01] <trentster> I have never used an encoder before(scratches head)
[03:26:16] <Wolf_> my BLDC servo has 8 wires… but 5 of them are really small
[03:27:00] <trentster> I am going to open to terminal and get a peek at the wiring
[03:27:43] <archivist> or read the label and google
[03:28:20] <trentster> archivist: there isnt a label on it
[03:33:41] <trentster> ok its def a stepper, and the encoder has 3 wires
[03:34:09] <trentster> stepper has 8 wires, i found the pairs by bridging and testing resistance
[03:35:07] <archivist> well a bldc is sort of a form of stepper but is known as AC servo
[03:37:37] <trentster> archivist: thanks, I am clueless about this. I will go and google it
[03:47:31] <trentster> archivist: can I drive this motor with regular pulse and direction from my cheapie BOB?
[03:47:53] <archivist> you need a driver
[03:48:31] <trentster> you have any suggestions on what to get?
[03:48:41] <archivist> if a plain stepper then an ordinary bipolar stepper driver will work
[03:48:42] <trentster> I already have drivers
[03:48:49] <trentster> for regular steppers
[03:48:54] <trentster> Leadshine Am882
[03:49:01] <archivist> try it
[03:49:18] <trentster> and if I want to use the encoder for position?
[03:50:14] <archivist> best to use hardware to read encoders, although if slow enough tou can use the bob to read an encoder
[03:51:19] <trentster> k thanks
[04:57:58] * XXCoder sighs
[04:58:09] <XXCoder> guy smashing into 2 cars says devil made him do it
[04:58:41] <sync> probably true
[04:58:51] <XXCoder> next time I scrap a part I'll tell boss devil made me do it
[04:58:58] <XXCoder> see how well it goes over
[04:59:37] <gonzo_> he'll say "No I didn't!"
[04:59:49] <XXCoder> lol
[05:00:06] <XXCoder> sadly devil does much less damage in bible :P
[05:52:41] <Tom_L> 13 f
[05:53:36] <XXCoder> its nice and white snow here, though around 26f now
[05:53:38] <archivist> yesterday I opened the door to let the warm in from outside :)
[05:53:41] <XXCoder> lemme use heat gun outside
[05:54:59] <archivist> 13.2c out 12.4 in today, just opened the door again
[05:55:34] <XXCoder> 30f on step, but dirt and snow is 25f
[06:44:21] <jthornton> zlog
[06:44:57] <XXCoder> hey
[06:45:06] <jthornton> morning
[06:45:07] <XXCoder> my reistors finally arrived!
[06:45:15] <XXCoder> can finally do autolevel soon
[06:45:21] <jthornton> cool
[06:46:05] <XXCoder> yeah
[06:55:46] <trentster> XXCoder: is that for a 3d printer?
[06:56:21] <XXCoder> the induction sensor? yeah
[06:56:55] <trentster> I saw this the other day and bookmarked it for my 3d printer build
[06:56:56] <trentster> https://www.indiegogo.com/projects/bltouch-auto-bed-leveling-sensor-for-3d-printers#/
[06:57:53] <XXCoder> yeah dont plan to use bltouch
[06:58:38] <trentster> no good?
[06:59:15] <XXCoder> dunno just already have plan
[07:00:06] <trentster> nice, I have always wanted a 3d printer, very useful thing to prototype
[07:01:14] <XXCoder> yeah
[07:01:22] <XXCoder> its heck of annoyance too lol
[07:02:25] <trentster> yeah, I have so much spare extrusion, etc, I figured I should build myself. But I may be in for a nightmare. Was planning on copying the Formbot T Rex, you heard of it?
[07:02:42] <XXCoder> dunno
[07:02:57] <XXCoder> I use prusa flsun clone i3 heh
[07:03:47] <trentster> your router machine finished?
[07:06:16] <XXCoder> no spindle still been too lazy to do anything. plan to finish inductor then see what can do with router, get ti fully functional (besides spindle)
[07:06:50] <trentster> cool
[07:11:17] <jthornton> installing the latest slic3r now, linuxmint 17.3 installed and updated
[07:11:43] <XXCoder> prusa version? need to find that and try compile that
[07:12:03] <jthornton> I think... what's the link to that one again?
[07:12:18] <XXCoder> dunno I had link I thought was prusa. it wasnt
[07:12:26] <XXCoder> gonna go bed though night
[07:12:45] <jthornton> see you later
[07:53:37] <Tom_L> jthornton, got the server configured last night
[07:53:48] <Tom_L> not online yet
[08:13:46] <jthornton> cool
[08:18:00] <jthornton> run into any problems?
[08:58:42] <Jymmm> If I drew a square with 1/2" radius corners, I've taken that as I could place a 1/2" ball or drillbit on the inside corner and it would fit flush for at least 90 degrees worth. But when I look at (in this case 3" exhaust) pipe, they describe it as centerline on one side to end of the other side, and I'm trying to SIMPLY (aka dumbass speak) correlate the two, and just confusing myself along the way
[09:00:58] <SpeedEvil> the assumption is the pipe diameter remains unchanged
[09:01:55] <SpeedEvil> So, a 3" pipe, with a centreline bend of radius 18" has an inner radius of 16.5"
[09:02:41] <Jymmm> One example (not the one I'm looking for)
http://www.roadraceengineering.com/parts/tweekerparts/radius.jpg
[09:03:28] <SpeedEvil> Well - yes - that's the above
[09:04:47] <SpeedEvil> Though perhaps confusing in that it's referring to the distance left-right only between the lines, and the ends are confusingly placed
[09:08:52] <Jymmm> http://www.sharpeproducts.com/store/Content/Images/CatImages/90-2Tangent%20Elbow_Drwng.jpg
[09:10:00] <Jymmm> Ok here they state "inside radius", is that a "better" way to describe than centerlin to end?

[09:11:39] <CaptHindsight> radiuses
[09:13:22] <gregcnc> looks like plenty of snow this weekend
[09:14:14] <CaptHindsight> is it snowing yet?
[09:14:46] <gregcnc> flurries today, but real stuff comes tomorrow afternoon and again sunday night
[09:14:48] <Jymmm> This 2" pipe has a 4.8" inside radius, so I would need a 8.8" x 8.8" box to ship it in?
[09:14:53] <Jymmm> http://www.sharpeproducts.com/store/aluminum-2-pipe-90-elbow-w-2-tangents-6-clr?productId=11663
[09:15:54] <Jymmm> (ignoring actual tangent length)
[09:17:25] <gregcnc> that one gives you inside rad and dia. so 4.8+2.4
[09:18:01] <Jymmm> gregcnc: Not 4.8+2.4+2.4 ?
[09:18:12] <gregcnc> no
[09:19:22] <CaptHindsight> global warming hah, winter is still cold
[09:20:15] <gregcnc> if working with center rad it would be 6 + 1.2, radius plus half diameter
[09:21:32] <gregcnc> capthinsight, some people interviewed polar bears and they had a different opinion
[09:21:56] <CaptHindsight> hah, microphones don't work in the cold
[09:23:19] <gregcnc> soon no one will have to go outside anyway
[09:24:01] <Jymmm> gregcnc: And some did not appreciate being interviewed...
http://imgur.com/a/fMGWl
[09:24:17] <gregcnc> lol
[09:24:19] <CaptHindsight> sit around in there welfare chairs with built in toilets watching TV all day
[09:24:27] <CaptHindsight> there/their
[09:26:32] <Jymmm> gregcnc: In other parts of the world, they feel they are just being walked all over from all sides...

[09:27:22] <CaptHindsight> polar bears look different with short hair
[09:29:33] <Jymmm> CaptHindsight: Short haired pandas have such attitudes...

[09:31:05] <CaptHindsight> "no matter how hard you try there is always someone out there dumber than you"
[09:40:06] <Jymmm> I have 100% patients for ignorance, ZERO tolerance for stupidity.
[10:20:10] <SpeedEvil> There is stupidity, and there is willfull stupidity.
[10:20:24] <SpeedEvil> Can't learn, and unwilling to put the effort in to learn are very different things.
[10:31:43] <Jymmm> Can't learn/just don't know ~= ignorance, and I'm okey with that. Unwilling ~= lazy (eh). But stupidity, that just runs deep and never worth the effort to even attempt to overcome. Telling someone not to do something n times and they keep doing the same thing
[10:33:38] <Jymmm> I say just remove all the warning labels and let evolution take it's due course.
[10:41:01] <yasnak> ^^
[10:41:46] <_methods> buckets everywhere
[10:42:24] <gregcnc> if it's buckets of coffee, I'm in
[10:46:31] <_methods> once trump shuts down the EPA evolution will occur even faster
[10:46:33] <Jymmm> gregcnc: Kona Coffee at that!
[10:46:44] <_methods> put some nice mutagenics back into the ecology
[10:48:13] <_methods> we're all going to evolve!!
[10:48:26] <roycroft> speaking of evolving
[10:48:34] <roycroft> as opposed to speaking of being dumb
[10:48:41] <roycroft> which might apply as well
[10:48:49] <roycroft> how do folks generally index tooling on a cnc lathe?
[10:49:17] <roycroft> hopefully this is my dumbest question of the day
[10:49:56] <gregcnc> quick change tool post, turret
[10:50:08] <roycroft> sure, that's how they're held and reindexed
[10:50:16] <roycroft> but how is the initial indexing done?
[10:50:24] <gregcnc> touch off
[10:50:34] <roycroft> of what?
[10:50:41] <roycroft> a piece of precision ground rod?
[10:50:43] <gregcnc> stock, toolsetter
[10:50:49] <roycroft> and then entering an offset to centerline?
[10:51:03] <gregcnc> you make a cut measure insert offset
[10:51:10] <roycroft> ok
[10:51:21] <roycroft> so pretty much like manual machining
[10:52:00] <roycroft> and indexing is done on the z axis to the centerline
[10:52:08] <gregcnc> ?
[10:52:18] <gregcnc> both axes need offsets
[10:52:47] <roycroft> sure
[10:52:49] <roycroft> but x can vary
[10:52:55] <gregcnc> so does z
[10:53:00] <roycroft> i assume you face, then index to that
[10:53:18] <roycroft> or index to an existing feature
[10:53:30] <gregcnc> whatever works for you
[10:54:12] <roycroft> on z, if you index to the centerline you don't have to rindex for every part
[10:54:16] <roycroft> reindex
[10:54:35] <gregcnc> has nothing to do with the part
[10:55:07] <roycroft> if you index to the outside of the part it would
[10:55:14] <gregcnc> no
[10:55:57] <gregcnc> you aren't indexing index, you have work offsets and tool offsets
[10:56:09] <roycroft> yes
[10:56:20] <roycroft> i am not explaining well, i suppose
[10:56:24] <roycroft> forgive me - it's friday
[10:56:50] <gregcnc> in lathe you only change Z work offset, as needed for the part length
[10:57:27] <roycroft> yes, that makes sense
[10:57:38] <gregcnc> tool offset tell the control where in the work coordinate system tool tips are
[10:57:52] <roycroft> so i have 5 tools in qc holders
[10:58:08] <roycroft> i enter tool offsets from center on each of them
[10:58:18] <gregcnc> X and Z
[10:58:21] <roycroft> and they are indexed to x forever, as long as i don't change them
[10:58:37] <gregcnc> makes sense, right
[10:58:37] <roycroft> for z i offset from face or feature?
[10:59:00] <roycroft> because that will vary from part to part
[10:59:09] <roycroft> even the same part, if removed and replaced
[10:59:20] <gregcnc> not relevant, as long as they are correct, Z0.0 must be the same for every tool
[10:59:24] <roycroft> right
[11:00:00] <roycroft> and can i stipulate z0.0 for one tool and index the other tools off the "master" tool?
[11:00:12] <archivist> yes
[11:00:13] <roycroft> ok
[11:00:24] <gregcnc> setting Z is no different than X
[11:00:24] <roycroft> sorry for the convoluted way of asking
[11:01:18] <roycroft> the best thing would be for me to get my new lathe, cnc it, and start experimenting
[11:01:20] <archivist> 0,0, for tool 1 then offset and orientation for the rest
[11:01:29] <roycroft> then i can ask a lot more stupid questions :)
[11:03:28] <roycroft> i'm leaning towards a 12x36 now
[11:03:36] <roycroft> but i need to sell a vehicle first if i'm going to do that
[11:03:37] <gregcnc> not necessarily 0,0 for tool 1
[11:03:54] <roycroft> this weekend i'll be taking pictures of the vehicle and prepping it for sale
[11:04:28] <archivist> I machine some bar measure the touch off the dia on tool 1 then the rest follow
[11:05:15] <archivist> more than one way of doing it
[11:05:31] <roycroft> sure
[11:05:31] <sync> touchprobe on the machine
[11:05:39] <roycroft> i think i have a good sense of the concept now
[11:05:45] <roycroft> which is what i was going for
[11:05:52] <gregcnc> sync, send it out and don't worry about offsets
[11:06:03] <skunkworks> roycroft,
http://linuxcnc.org/docs/html/lathe/lathe-user.html#_tool_touch_off
[11:22:33] <roycroft> thanks, skunkworks
[11:22:46] <roycroft> a succinct summary of the procedure helps a lot
[11:23:06] <skunkworks> I have used it - I am not a lath person - so it helped a ton
[11:23:11] <skunkworks> laith
[11:23:16] <skunkworks> heh
[11:23:17] <skunkworks> lathe
[11:23:41] <CaptHindsight> skunkworks: are you rebuilding an EDM?
[11:24:26] <skunkworks> we bought a sinker edm that was 'some assembly required'...
[11:24:39] <archivist> kit
[11:24:49] <skunkworks> we are missing the dielectric tank and pump but have 90% of the parts figured out.,
[11:25:36] <CaptHindsight> I have to put one back together as well
[11:26:53] <skunkworks> it is a hansvelt 30amp machine
[11:26:57] <roycroft> i still don't have room for a 12x36, but every time i look at a smaller one i see features missing that are available on the 12x36 and above
[11:27:06] <roycroft> not to mention the greater mass of the larger lathe
[11:27:27] <roycroft> so it's looking like i need to rearrange my shop
[11:27:40] <skunkworks> CaptHindsight,
http://electronicsam.com/images/matsuura/20161129_160909.jpg
[11:29:09] <CaptHindsight> skunkworks: tank and pump are the easy parts for that size
[11:29:57] <skunkworks> yes - we have a tank - ebayed a pump and found a filter housing that will work with 5 micron filters we found
[11:30:23] <skunkworks> The controls for the dielectric are on the side of the table so we have all the valving and such.
[11:30:28] <CaptHindsight> I'm moving to a bigger space
[11:30:46] <CaptHindsight> so I'll have to reassemble quite a few machines
[11:31:30] <skunkworks> nice!
[11:31:44] <CaptHindsight> https://chicago.craigslist.org/nwc/tls/5900437479.html don't have time to get this
[11:33:46] <CaptHindsight> it's works, it just needs some TLC
[11:34:32] <roycroft> sometimes i wish i lived in the rust belt
[11:34:41] <roycroft> so much more equipment available
[11:35:13] <roycroft> but i'm so much happier where i am - i grew up in chicago and have never looked back since i left
[11:35:48] <CaptHindsight> I'm only in the city for a few hours a month
[11:36:22] <skunkworks> CaptHindsight, that is yours?
[11:36:38] <CaptHindsight> skunkworks: no it's available nearby
[11:36:48] <CaptHindsight> in Rockford
[11:37:43] <CaptHindsight> skunkworks: I recall your VMC projects. Do you need a lathe?
[11:38:47] <skunkworks> if you see to the left of the edm is a mazak...
[11:39:18] <skunkworks> and we have a cincinati malicron we need to get running some day.. (and a monarch and a large engine lathe..)
[11:39:25] <skunkworks> and some emcos...
[11:39:36] <skunkworks> I think we are good with lathes for now. :)
[11:39:41] <CaptHindsight> skunkworks: which model? I've been eyeing a 4 axis
[11:39:54] <skunkworks> it is a quick turn 20 iirc
[11:39:59] <skunkworks> nothing fancy
[11:40:17] <skunkworks> still runs the original mazatrol control. dad likes it - I have never used it.
[11:40:34] <CaptHindsight> http://www.ebay.com/itm/291854804482 looking for similar
[11:41:10] <skunkworks> I will never understand why anyone would convert a manual anymore ;)
[11:41:22] <skunkworks> 3500 for a cnc lathe.
[11:41:28] <CaptHindsight> yeah
[11:41:35] <skunkworks> even with shipping - that is a steel
[11:41:43] <CaptHindsight> well it's most often budget
[11:41:55] <gregcnc> usually they are too big
[11:42:08] <CaptHindsight> $1K manual lathe and $1k parts
[11:42:16] <jdh> I have never seen a reasonable priced cnc lathe
[11:42:17] <CaptHindsight> 200 hours of their time
[11:48:40] <gregcnc> https://www.govdeals.com/index.cfm?fa=Main.Item&itemid=103&acctid=8907
[11:49:03] <skunkworks> wait - is it made out of clay?
[11:49:25] <gregcnc> https://youtu.be/TqokK03BJsM?t=2m7s
[11:50:47] <CaptHindsight> cantilever mill
[11:51:20] <gregcnc> big enough to mill a car
[11:51:34] <CaptHindsight> with linear motors
[11:51:36] <sync> not uncommon
[11:52:41] <CaptHindsight> probably handles PLA as well :)
[11:54:06] <CaptHindsight> https://youtu.be/UFNEqY6nn0g?t=4m19s that video gave me this suggestion
[11:56:06] <CaptHindsight> pretty narrow crank journals
[11:58:07] <CaptHindsight> the guy with the IKEGAI will store it
[12:31:03] <IchGucksLive> hi
[12:42:45] <roycroft> what sucky design
[12:42:51] <roycroft> i had to move a server
[12:42:53] <roycroft> so i powered it down
[12:43:01] <roycroft> after moving it it would not come back up
[12:43:03] <roycroft> no power at al
[12:43:04] <roycroft> l
[12:43:07] <roycroft> cmos battery was dead
[12:43:24] <roycroft> i removed the cmos battery, but it would not even power on with defaults or to bring me to a setup menu
[12:43:34] <roycroft> i had to go buy a new battery before i could power it on
[12:43:43] <roycroft> this in a production environment
[12:44:03] <roycroft> of course, i bought two batteries and taped the spare inside the server enclosure
[12:44:41] <jdh> cr2036?
[12:44:56] <jdh> I have a box of those at my desk
[12:45:14] <roycroft> cr2032
[12:45:52] <roycroft> it would have been nice if the machine would power up without the battery
[12:45:57] <roycroft> so i could get it online again quickly
[12:46:08] <roycroft> and then schedule another maintenance window to replace the battery
[12:46:21] <IchGucksLive> Deejay: ?
[12:46:23] <jdh> heh. that's the one
[13:28:05] <_methods> anyone happen to have a manual for a hansvedt mv10?
[13:28:14] <_methods> just picked one up for $1200
[13:28:23] <_methods> not sure if any of the docs are with the machine
[13:36:47] <IchGucksLive> Gn8
[13:37:17] <MacGalempsy> hello guys and gals
[13:38:35] <JT-Shop> hola
[13:38:52] <MacGalempsy> JT-Shop: hard at work today?
[13:39:53] <JT-Shop> yea, had to trouble shoot a 11 router table out in the middle of no where
[13:41:27] <JT-Shop> now I have to go to the industrial park and program a core mule
[13:47:41] <XXCoder> fancy
[13:48:36] <MacGalempsy> sounds professional
[13:50:45] <JT-Shop> the router table makes wall panels, cutting the foam out where the 2bees go
[13:53:52] <JT-Shop> BBL
[13:57:23] <andypugh> Clever.
https://www.youtube.com/watch?v=8ekioGZOkb4&list=PLJcTWL2wr19FadkNlS5B95crynLjqRDXI
[13:58:36] <_methods> yeah that's slick
[13:59:51] <_methods> wonder how thin he can get the traces doing that
[14:00:06] <_methods> i guess it would be height dependent
[14:09:25] <CaptHindsight> 405nm with a decent lens maybe down to 5-10um lines
[14:10:47] <CaptHindsight> from the last images it looks likes he's 10x larger than that
[14:11:56] <sync> several people have built similar things with a polygon mirror and a single linear stage
[14:13:18] <cradek> that's awesome
[14:13:29] <cradek> are there brushes?
[14:13:53] <andypugh> Yes, there are brushes for the laser power.
[14:14:20] <andypugh> You could do it with a hollow-shaft motor and mirrors rather nicely too.
[14:14:52] <sync> yeah or just use a polygon mirror :D
[14:15:05] <andypugh> (and how hard would it be to make any motor hollow-shaft enough?
[14:15:21] <CaptHindsight> ~200um lines is what the cheapo DLP printers get with 405nm lasers
[14:15:22] <sync> probably not very, as you only need like 5mm
[14:15:39] <andypugh> sync: Well, yes, but this is using nothing special at all, which is part of the cool.
[14:15:50] <CaptHindsight> and the $100 galvo sets
[14:15:59] <sync> a polygon mirror os nothing special at all
[14:16:11] <sync> you get hundereds of them out of laser printers
[14:16:21] <andypugh> sync: I disagree. I don’t have one.
[14:16:43] <andypugh> Well, I might have one in my laser printer. My dead laser printer.
[14:16:49] <sync> you do.
[14:17:01] <sync> see, nothing special
[14:17:07] <andypugh> I might have 4
[14:17:15] <andypugh> It’s a colour printer
[14:17:32] <andypugh> (and I don’t know how it works)
[14:18:43] <CaptHindsight> laser + polygon mirror or it has a row of IR led's
[14:20:55] <andypugh> eBay accident. I bought a laser printer on eBay. I got an unexpected phone call from the delivery chap. “I got the pallet as far up your path as I could” Huh? Turns out the vendor had used a stock photo that didn’t include the 1500 sheet 4-layer feeder. I came home to this:
https://goo.gl/photos/tL8GWfwRvDm1vXTS9
[14:21:38] <cradek> ha
[14:22:15] <andypugh> Getting that upstairs single-handed was one of the more major exertions of my life.
[14:22:30] <XXCoder> crazy
[14:22:41] <XXCoder> did it damage your nice walkway
[14:23:08] <andypugh> No, it was all fine.
[14:23:09] <sync> haha mine was similar
[14:23:23] <sync> but yeah they are annoying to carry
[14:23:49] <andypugh> But, it’s out of black toner. And when toner is £175 per colour that’s a dead printer.
[14:24:32] <sync> huh
[14:24:34] <sync> how so
[14:24:41] <andypugh> (To be fair, that’s enough toner for somethign like 20,000 pages)
[14:24:48] <sync> just get a refill kit
[14:24:54] <sync> or just buy a new cartridge
[14:25:19] <andypugh> £175 is the price of the new catridge
[14:25:33] <bpuk> a lot of the 4 colour printers include a transfer drum inside the toner cartridge - hence the crazy prices
[14:25:53] <sync> yeah, that's not too bad andypugh
[14:25:59] <andypugh> And it is not feedin paper right, either.
[14:26:47] <andypugh> But, I can get a cheap printer for less money, reclaim a significant prportion of my living space, and mine it for motors and parts.
[14:28:50] <bpuk> I'm kinda curious what printer it is now
[14:36:52] <andypugh> Tektronix Phaser 7600
[14:37:28] <andypugh> I bought it because the advert listed a very high resolution. It was wrong.
[14:39:51] <bpuk> hadn't realised any of the phaser's were laser - learned something new
[14:40:39] <andypugh> I do really like the idea of a solid ink one. But for the use I have (I print about once a month) one of those would be stupid.
[14:51:34] <XXCoder> https://www.youtube.com/watch?v=k9rtVHuV9ZI
[14:51:37] <XXCoder> interesting
[15:11:12] <srdc> Howdy yall ... I'm trying to integrate a Mazak VMC with LinuxCNC using Mesa 7i80 + 7i49 (resolver/servos) & some GPIO boards. This is our 2nd CNC mill
[15:11:37] <srdc> Anyway, when I load LinuxCNC, it's giving an error
[15:14:11] <srdc_> Sorry ... my computer froze, so any responses I missed
[15:14:29] <srdc_> We are getting some errors while trying to load LinuxCNC (working in CLI right now)
[15:15:03] <srdc_> Just a sec --- have to reload them now
[15:15:33] <srdc_> First is: hm2_eth: ERROR: used llio->read in realtime task (addr=0x3a00)
[15:15:50] <srdc_> Then: emc/task/emctask.cc 389: interp_error: All axes missing with g92
[15:16:15] <srdc_> Then a bunch of: waiting for s.axes
[15:16:35] <srdc_> Then: A configuration error is preventing LinuxCNC from starting.
[15:16:59] <srdc_> Not quite sure which of those are most important, or where to start untangling the knot ... any ideas?
[15:18:08] <andypugh> Which kernel are you using?
[15:18:37] <andypugh> (uname -a)
[15:20:52] <srdc> Alright ... looks like some issues with that computer. On another one. Again, if anybody responded, I missed it...
[15:22:13] <srdc> Anybody have any ideas?
[15:42:25] <srdc> So in the debug file it says "waiting for component trivkins to become ready" and then 'giving up'
[15:42:38] <srdc> Why would trivkins not load properly?
[15:44:26] <cradek> you probably need to look before that
[15:44:49] <srdc> mmmmk
[15:45:01] <srdc> in the debug file, or in the CLI failure messages?
[15:45:42] <cradek> andy asked you what kernel you are running and I didn't see a response
[15:46:04] <srdc> I'm sorry - i was on another computer and it kept freezing with Firefox ... so I didn't see the question.
[15:46:56] <srdc> It's 4.1.35 with the RT 41 patch on Debian 8 with LinuxCNC 2.7 uspace from the buildbot
[15:47:26] <srdc> It's been working fine with the sim config, but now we're in the process of connecting the actual machine
[15:47:52] <cradek> I'm not up on what rt-preempt kernels/patches work
[15:48:06] <cradek> can you pastebin the whole dmesg including a boot and failed run?
[15:48:19] <cradek> dmesg|nopaste
[15:48:20] <srdc> Sure...give me a few minutes
[15:51:48] <srdc> Alright ... I'm not sure what nopaste is, but it doesn't like it. Command not found.
[15:51:53] <srdc> What am I missing?
[15:52:11] <cradek> I guess it's not installed (it is by default when you use the linuxcnc cd, and I assumed)
[15:52:31] <cradek> just use pastebin however you usually do
[15:52:47] <cradek> or install libapp-nopaste-perl if you like
[15:59:28] <Deejay> gn8
[16:00:06] <srdc> Here's the pastebin:
http://pastebin.com/u8qiqKs8
[16:03:02] <cradek> ok, no smoking guns, also have the linuxcnc messages?
[16:04:04] <srdc> Sure, just another minute
[16:04:32] <srdc> I had them, but made some changes (switched Gmoccapy --> Axis & switched off remapping to simplify things) so I need to re-output it
[16:09:33] <srdc> http://pastebin.com/vbAFvdpj
[16:09:48] <andypugh> Ah, this is a uspace kernel isn’t it? So linuxCNC errors go somewhere ill-defined.
[16:09:58] <srdc> Yes
[16:10:36] <srdc> I'm running uspace, because i'm using the 7i80 (ethernet) board ... so Peter told me I had to run uspace
[16:10:46] <cradek> wait, did you type g92 somewhere?
[16:10:58] <andypugh> Yes, you have to. (My first guess was that you weren’t)
[16:11:11] <cradek> > iptables: No chain/target/match by that name.
[16:11:12] <cradek> this seems wrong
[16:11:18] <andypugh> I am wondering if there is a G92 in startup G-code
[16:11:22] <cradek> > hm2_eth: ERROR: used llio->read in realtime task (addr=0x3a00)
[16:11:22] <srdc> @cradek That seemed wrong to me too
[16:11:24] <cradek> this also seems wrong
[16:11:30] <srdc> But I don't know where the G92 would come from
[16:11:33] <cradek> but I think the error is with whatever is sending your g92
[16:11:54] <srdc> I had an M6 remap, but I commented that out in the ini file in case that was being read wrong
[16:12:41] <cradek> do you have a startup gcode?
[16:13:02] <andypugh> hm2_eth: ERROR: used llio->read is probably my fault, and is likely to be related to setting parameters somewhere. It’s a bit of an over-zealous warning about code that bypases TRAM.
[16:13:41] <srdc> Ummmm...I don't think so. Let me check the ini file (anywhere else it could be?)
[16:14:21] <srdc> Nevermind
[16:14:30] <srdc> I do have G92 in the startup gcode
[16:15:39] <srdc> And I forgot to put the offsets. Probly why that's fussing. Let me fix that and run again
[16:15:45] <andypugh> What was that intended to do?
[16:16:08] <andypugh> You might have meant G92.2?
[16:17:02] <andypugh> Setting offsets in startup code is morally questionable.
[16:17:22] <srdc> Probably did. I don't remember now. I wrote that line LATE one night...
[16:17:27] <cradek> yeah seems unlikely to be what you want...
[16:18:02] <srdc> IIRC, I copy-pasted from the docs as a placeholder, and meant to come back and tune it to what was needed
[16:18:16] <srdc> It's running now!
[16:18:19] <srdc> Thanks!
[16:19:49] <cradek> yay
[16:22:11] <andypugh> srdc: Work coordinate systems (G54 and friends) are sticky through restart. They should do what you want.
[16:23:14] <Tom_L> ot but what linux utility can i use to burn a bootable iso image to a cd?
[16:24:23] <cradek> cdrecord
[16:26:46] <Tom_L> wodim apparently replaces it
[16:26:47] <Tom_L> now
[16:31:17] <srdc> andypugh: thanks!
[16:39:38] <MacGalempsy> well shit. I broke this liftgate hinge while trying to take it apart for measurement.
[16:40:13] <MacGalempsy> it is interesting that it came off a toyota, but the dimensions for the tube are imperial
[16:59:25] <JT-Shop2> I use Brasero

[17:55:04] <zeeshan-laptop> another experiment nice!
[17:55:04] <XXCoder> hey laptop of zeeshan
[17:55:05] <zeeshan-laptop> nite
[17:55:06] <zeeshan-laptop> :D
[17:55:17] <JT-Shop2> did it blow up?
[17:55:45] <XXCoder> any experiment that results in crater is good science
[17:55:57] <JT-Shop2> lol
[17:55:57] <zeeshan-laptop> haha no
[17:56:07] <zeeshan-laptop> but when a smaller liquid n2 tank doesnt work
[17:56:09] <zeeshan-laptop> you get a big ass one!
[17:56:24] <JT-Shop2> I re-installed linuxmint 17.3 so I can try slic3r prusa with a clean slate
[17:56:33] <JT-Shop2> if that don't work then it's linuxmint 18

[17:57:28] <JT-Shop2> I can't get on efnet any more :( Tom needs to move
[17:57:36] <zeeshan-laptop> why not
[17:57:43] <JT-Shop2> won't connect
[17:58:19] <zeeshan-laptop> try irc.prison.net
[17:59:04] <JT-Shop2> how do you try that?
[17:59:23] <roycroft> irc.nac.net is generally open
[17:59:25] <XXCoder> /server irc.prison.net
[17:59:37] <roycroft> good luck slumming it on efnet!
[17:59:38] <XXCoder> mines on automatic
[17:59:58] * roycroft used to operate a server on efnet, and so is allowed to say whatever he wants about it :)
[18:00:04] <XXCoder> im on espernet freenode and moblereadnet lol

[18:01:29] <JT-Shop2> irc.nac.net worked thanks roycroft
[18:13:22] <JT-Shop> much warmer here
[18:15:56] <JT-Shop> I wonder if you can configure hexchat to use a server
[18:17:02] <XXCoder> should be

[18:26:34] <XXCoder> interestin
[18:27:15] <JT-Shop> I don't see a way to tell efnet to use /server irc.nac.net

[18:42:12] <MacGalempsy> this is looking good. three machined pieces and the rest costs about $13
[18:43:39] <BeachBumPete> ?
[18:45:18] <andypugh> SpeedEvil: Looks strangely bodged
[18:45:40] <andypugh> I would have expected custom-formed induction coils.
[18:46:13] <SpeedEvil> remember these are barely more than handmade.
[18:46:21] <SpeedEvil> quantities of a few hundred
[18:46:39] <andypugh> I should ask for a job. I can do metal spinning.
[18:55:42] <DaViruz> i just ordered a bunch of stainless steel spinnings from aliexpress
[18:56:36] <DaViruz> i hope they can as well!
[19:00:22] <andypugh> I have had a bad experience with Alibaba. $100 for a 10kg sample of brass. Good. money sent. + $150 shipping. Less good, but still OK. Several days of emails, they can’t get the money out of Western Union. Ask me to send again. I refuse. Eventually they get the money. But realise that they have miscaclulated shipping (or so they say) and send me 5kg.
[19:01:26] <andypugh> So, I have spent £250 on something I could have had from eBay weeks ago for £100.
[19:01:47] <BeachBumPete> ouch
[19:01:58] <DaViruz> aliexpress is somewhat a different deal though
[19:02:04] <XXCoder> complained to alibaba?
[19:02:14] <andypugh> But, as a friend said. You can’t fix it, just forget it and use the metal.
[19:03:09] <andypugh> I _closed_ a complaint to Alibaba when they got the money out and sent the stuff, but before they admitted that they had only sent half of what I ordered.
[19:04:29] <andypugh> From their point of view it’s a sample. They were quoting $5200 per ton. I can see how they think that sending a smaller sample for the shipping recieved is reasonable.
[19:05:08] <Wolf_> tell them sample size it to small and you’ll be looking to go with someone else then
[19:05:42] <andypugh> But, if I go to parcelmonkey.co.uk I can book a 10kg shipment from China to the UK for $50, not the $300 they said it cost.
[19:06:05] <andypugh> Wolf_: Thing is, the sample is more than I actually need.
[19:06:17] <Wolf_> they don’t know that...
[19:06:47] <andypugh> They do, I have been fairly straight with them about that. I thought that they were being straight with me.
[19:07:06] <Wolf_> ahh
[19:09:39] <andypugh> I don’t _think_ that they are actively trying to rip me off. It’s just miscommunication. They are probably wishing that they had said “no” to me initally, the woman I am dealing with won’t see any of the money, and the sums involved are tiny to them, I suspect.
[19:10:25] <wzl> hi all. Andypugh: you commented in a issue about a m6 remap in github, do you actually see the error in your system? I want to make sure that the problem its not in my install
[19:10:55] <andypugh> I can’t recall seeing it.
[19:11:33] <andypugh> Let me try the steps listed to reproduce it.
[19:13:25] <wzl> ok, thanks. I'm compiling linuxcnc with a bit of debug in a pentium 4 right now so I can wait.
[19:15:00] <andypugh> OK. I _DO_ see the error.
[19:15:05] <andypugh> with LINUXCNC - 2.8.0~pre1
[19:15:40] <andypugh> Does it stop G-cde execution, I wonder?
[19:15:48] <wzl> fine then
[19:16:09] <andypugh> I would be happier if it was only you :-)
[19:17:33] <Frank_6> guys, little question, i want to make a bearing housing for me belt reduction drive, is this decent? or i am missing something?
http://imgur.com/a/QWW5A there is a shoulder in the design to push the bearings up until de end of the housing, maybe someone can point me towards some info about them
[19:18:15] <wzl> I have'n run any g code yet
[19:20:07] <andypugh> Frank_6: Is that your design?
[19:20:14] <Frank_6> yes sir
[19:20:51] <Frank_6> im still learning fusion 360
[19:21:05] <andypugh> It might be perfect, or hopeless. It depends on what it needs to do.
[19:21:29] <andypugh> Let me find the SKF guidelines on bearing housing design.
[19:21:41] <zeeshan-laptop> drill a hole
[19:21:42] <zeeshan-laptop> good to go
[19:24:16] <Frank_6> oh, i didnt knew they had those, ill search them. the bearings that go inside them are 25mm ID and the skf 6005 item showed about 20k rpm max and 6kn of force to break those, as far as bearings they should be good, i should check if the bearing is strong enough and the boring clearance
[19:24:35] <zeeshan-laptop> those are static ratings
[19:24:59] <andypugh> Frank_6: It’s not so clear, but the left-bar is the tree, the red dot is where you are, and he headings on white rather than blue are the sib sections.
http://www.skf.com/uk/products/bearings-units-housings/ball-bearings/principles/design-considerations/index.html
[19:25:33] <andypugh> You should read the first three sections for certain, and the rest are useful too.
[19:26:07] <Frank_6> sounds good, thanks andy
[19:27:05] <andypugh> I read it all years ago, and it’s really useful. You, too, will soon be able to spot badly designed systems all over the place. Including nearly every motorcycle wheel.
[19:29:56] <Frank_6> lol
[19:40:27] <MacGalempsy> anyone got a small lathe they want to part with for free?
[19:40:44] <MacGalempsy> or trade for a 3p drill press?
[19:50:24] <Tom_L> JT-Shop around?
[19:56:54] <Frank_6> good night everyone
[22:22:16] <XXCoder> hey
[22:22:35] <XXCoder> what gauge wires is good for wiring from BOB to tb660s?
[22:23:18] <XXCoder> and can I just connect all tb660s + together and grounds together on approtate connectors on power box?
[22:23:25] <XXCoder> or is it bad idea?
[22:41:56] <Wolf_> awg depends on current, and all to the same psu should be fine, not daisy chained though
[22:42:25] <XXCoder> indeed. series vs parallel
[22:42:46] <XXCoder> I dont know what current BOB uses to commucate with tb660s
[22:42:59] <XXCoder> probably can be fairly low gauge
[22:43:03] <XXCoder> *higher
[22:43:27] <Wolf_> very low
[23:01:50] <pink_vampire> hi
[23:01:56] <XXCoder> hey pink_vampire
[23:02:30] <pink_vampire> how is the tool length sensor work?
[23:03:00] <XXCoder> machines I use at work use laser to detect tip
[23:03:06] <XXCoder> sometimes spinning tool sometimes not
[23:03:17] <XXCoder> facemills tend to spin for that for example
[23:03:27] <pink_vampire> http://www.sme.org/uploadedImages/Publications/ME_Magazine/2013/January_2013/EmhTS3520%281%29.jpg
[23:03:49] <pink_vampire> i mean how i set it up in the linux cnc
[23:04:02] <pink_vampire> it fixed to the table
[23:04:11] <XXCoder> ah that type. yeah its nice. no idea unfortunately heh
[23:04:42] <pink_vampire> i know they like a probe.
[23:05:06] <XXCoder> I recall someone talking about configuring a script for that
[23:05:21] <XXCoder> move tool to x, y then slowly lower till triggered
[23:05:30] <XXCoder> then back off and even slower lower for more accurate
[23:05:36] <pink_vampire> but i'm using collets, so the tool length of the probe is not fixed
[23:05:43] <XXCoder> then it sets tool length
[23:06:23] <wzl> Hi all , who is john@zultron.com?
[23:07:05] <pink_vampire> but how it's know where is the top surface of the stock?
[23:07:47] <Wolf_> thats when you touch off the work
[23:08:27] <XXCoder> work I usually do this, use 123 block, use probe (or dial indicator) set zero, then find difference from that block to top surface
[23:08:37] <XXCoder> lower than 123 block should be negative z, postive higher
[23:08:49] <XXCoder> all tools must set length touching that same block
[23:09:17] <XXCoder> with automated tool touchoff tool I dont know how to find part top Z
[23:09:26] <pink_vampire> but i want to probe the work, and touch the tool, but the problem is that i'm not using fixed tools holders, i'm using collets
[23:11:10] <Wolf_> that I’m not sure about…
[23:12:07] <XXCoder> I saw some tool auto touchoffs that just use steel plate
[23:12:26] <XXCoder> but if wiring fails or for some reason tool wasnt conductive enough well theres now a nice dent on table
[23:12:33] <XXCoder> or nicely chipped tool
[23:13:14] <pink_vampire> is the probe is in fixed holder it's fine, but in my case the length of the prove is change every time you insert it to the collet
[23:14:51] <XXCoder> well like I said before you can change it to some fixed and known and repeatable position
[23:14:56] <XXCoder> like 123 block on top of jaw
[23:15:07] <XXCoder> *vise
[23:15:31] <XXCoder> how do you set tool lengths?
[23:15:40] <XXCoder> after probeing location of stock
[23:15:52] <XXCoder> I'm curious on your setup procure
[23:16:09] <pink_vampire> and i saw guys on youtube that use some touch plate, but is work the opposite from a probe (probe is NC, plate is NO) so how i connect them to the bob?
[23:16:26] <Wolf_> for mine, touch off after each tool change
[23:16:57] <XXCoder> careful with plate, test it by touching tool manually with plate see if it detects and stops, then do touchoff with plate on surface heh
[23:17:33] <XXCoder> I dont use automated anything - like tool length and xyz coord find
[23:17:42] <pink_vampire> now i just touch the tip of the tool on the top of the stock (very gently by eye, and 99% it's fine)
[23:18:21] <XXCoder> the cell I place tool holder with tool on 2 123 blocks where reference point rest on 123 blocks and check length from top 123 to highest point in tool and find length that way
[23:18:59] <XXCoder> you use er collets so thats not applicable heh
[23:19:25] <Wolf_> I’m planning on going with TTS tool holders so I can do preset tool length
[23:19:35] <XXCoder> do you use CAT40 or is your spindle direct tool mount with for example er16?
[23:19:56] <XXCoder> I dont know names of smaller variants of that.
[23:19:58] <Wolf_> probably R8
[23:20:56] <pink_vampire> the tts is nice, but i don't like the extra length of them..
[23:21:12] <XXCoder> http://www.tormach.com/uploads/images/Gallery/products/tts/tool_sets/30188-TTS-Manual-Operators-Set-w-black_MG_5363.jpg
[23:21:15] <XXCoder> interesting.
[23:21:18] <Wolf_> yeah, trade offs
[23:21:42] <XXCoder> wolf I see that it has flat bottom you could stand it with 123 blocks and find tool length and use that as reference surface too
[23:21:49] <XXCoder> not surface point
[23:22:02] <Wolf_> I have the granite plate with a 3/4” hole in it
[23:22:08] <XXCoder> nice
[23:22:33] <codepython777> When you cut alum, is there a way to pull the flakes using a vacuum/fan - or should i just blow the flakes?
[23:22:47] <Wolf_> either pick one
[23:22:51] <XXCoder> can do both actually
[23:22:58] <XXCoder> blow one side and suck other side
[23:23:06] <XXCoder> will still leave some mess but less
[23:23:18] <XXCoder> shop vac can do both lol
[23:23:41] <XXCoder> so answer is either or both
[23:23:51] <pink_vampire> https://youtu.be/Kt8ueNzUEBA
[23:24:28] <XXCoder> nice video
[23:24:43] <codepython777> XXCoder: can you link me a good shop vac please? :)
[23:25:06] <XXCoder> https://www.youtube.com/watch?v=zzt12DKN_YY this is same as one I run
[23:25:50] <XXCoder> 24 tombstones, 2 horzional mills, 2 wss
[23:25:57] <XXCoder> one in video is even bigger
[23:26:47] <codepython777> XXCoder:
http://www.grizzly.com/products/1-HP-Wall-Hanging-Dust-Collector/G0710?utm_campaign=zPage&utm_source=grizzly.com ?
[23:27:11] <XXCoder> woul that be able to handle alum chip abuse?
[23:27:18] <XXCoder> I dont think so?
[23:27:51] <codepython777> XXCoder: is there a good one that you would recommend that costs < $200?
[23:28:17] <codepython777> I dont have too much space either
[23:28:19] <XXCoder> I do like regular shopvac but I also dont know if that can abuse alum chip abuse either
[23:28:22] <Wolf_> home depot shopvac…
[23:28:25] <XXCoder> *handle
[23:28:30] <XXCoder> wolf yeah
[23:28:46] <Wolf_> should be fine, filter before the motor
[23:29:20] <codepython777> Wolf_: the filter wont go bad?
[23:29:32] <Wolf_> or add a dust deputy before the shop vac
[23:29:52] <XXCoder> DO NOT RUN -60!
https://www.youtube.com/watch?v=ZuahgxI7OCE heh
[23:30:07] <Wolf_> filters get clogged up, by design
[23:30:33] <XXCoder> that setup is little better than one I use. no crane at my station bahh
[23:30:39] <XXCoder> though most times dont need em
[23:33:03] <codepython777> http://www.homedepot.com/p/Vacmaster-8-Gal-HEPA-Industrial-Vacuum-with-2-Stage-Motor-VK811PH/203024027
[23:33:22] <codepython777> Wolf_: what do you need to use a machine like that? Is it even usable for eating alum chips?
[23:33:30] <XXCoder> codepython777: make a seperator
[23:33:36] <XXCoder> so it barely gets any chips.
[23:33:45] <XXCoder> lemme link a sec
[23:35:03] <XXCoder> https://www.youtube.com/watch?v=1UnPU46kluE
[23:35:32] <Wolf_> I would get a normal in stock 4gallon shop vac and a 5 gallon bucket +
http://www.oneida-air.com/category.asp?Id=%7BCC6B6F2A-E3D7-4F18-A53C-B5C357DFE131%7D&_vsrefdom=adwords&gclid=CjwKEAiAyanCBRDkiO6M_rDroH0SJAAfZ4KLxSgQLEfpGtw-mEPlIj6kBnrEaQ31uWKV1TqGUWPZXBoCtMvw_wcB
[23:35:41] <XXCoder> oh look at that
[23:35:59] <XXCoder> he sucked up entire box of wood chips, and virtually none entered vacuum system
[23:36:12] <Wolf_> I have one mounted on a 30gallon plastic drum
[23:37:17] <XXCoder> I plan to attempt to make dyson-style seperator see if it works for wood chips
[23:37:30] <XXCoder> 4 of cyclones around the sealed bucket
[23:37:42] <XXCoder> then to shopvac
[23:38:04] <Wolf_> http://www.oneida-air.com/inventoryD.asp?item_no=AXD001004&CatId={6EE79B16-EB63-43E7-8F30-1E06240A24A4} and a
http://www.homedepot.com/p/RIDGID-16-Gal-6-5-Peak-HP-Wet-Dry-Vac-WD1851/100638360 but should work fine with a smaller shopvac and 5 gallon bucket setup
[23:38:10] <XXCoder> that guy in video is pretty young
[23:38:29] <XXCoder> Wolf_: Al chips would eat that
[23:38:35] <Wolf_> nope
[23:38:47] <Wolf_> works fine when I use it with my mill
[23:38:48] <codepython777> Wolf_: thanks! Even with that dust deputy, the alum chips will get inside the filter, right? and kill it?
[23:38:56] <XXCoder> it dont break under abuse of alum chips?
[23:39:13] <XXCoder> codepython777: seperator helps a lot
[23:39:33] <Wolf_> nope, dust deputy takes the chips out, I’ve used it to also suck up plaster in my house
[23:39:33] <codepython777> helps a lot means it breaks the system in 2 days instead of 2 hours?
[23:40:03] <XXCoder> forever as long as you empty seperator bin basically. check vacuum system daily if heavy usage for tiny buildup
[23:40:19] <XXCoder> (everything wears down but yeah)
[23:40:28] <Wolf_> I use a bag insert + hepa filter in my shop vac
[23:40:40] <Wolf_> but its way overkill
[23:41:03] <codepython777> Wolf_: is there a reason to get a steel one?
[23:41:04] <Wolf_> change the bag out once a year unless it starts sounding clogged
[23:41:13] <Wolf_> not really
[23:41:41] <XXCoder> Wolf_: im sure seperator bucket has to be sealed also in order to keep vacuum system working
[23:41:46] <XXCoder> am I correct?
[23:41:58] <Wolf_> yeah
[23:42:09] <trentster> I need to buy an air compressor for coolant and clearing chips for DIY hobby use, any pointers on what I hould try get hold of on ebay?
[23:42:25] <XXCoder> yea. thats why my plan for dyson includes sealed bucket system
[23:42:28] <Wolf_> nice that oneida-air link sucks… go to the dust deputy tab
[23:42:29] <codepython777> Wolf_: thanks. A regular vacuum near the spindle will pick up the alum chips?
[23:43:00] <Wolf_> http://i.imgur.com/LCeejCV.jpg yup
[23:43:04] <XXCoder> only have experence with wood on that respect
[23:43:30] <Wolf_> stringy chips will clog the hose
[23:43:48] <Wolf_> but that has only happened to me drilling or with lathe work
[23:44:08] <XXCoder> codepython777: woodgears version
https://woodgears.ca/dust_collector/separator.html
[23:44:52] <codepython777> I like cyclone :)
[23:44:56] <XXCoder> he later made better version, and had report on why he didnt bother upgrade that one
[23:45:17] <wzl> do you know about the cyclones of bill pentz?
http://billpentz.com/woodworking/cyclone/ I have a scaled back made from 6 inch pvc pipe connected to a shopvac
[23:46:50] <Wolf_> http://a.co/59ubofl
[23:47:05] <codepython777> Wolf_: in that picture, the sucking tip is very near the spindle. Do I need that? I was going to try to attach it to the spindle movement arm, so that it moves around with the spindle
[23:47:50] <Wolf_> brush head for the spindle IMO on the router
[23:47:59] <trentster> This is what I use mounted on top of a bucket, works like a dream:
http://www.ebay.com.au/itm/like/322026718895
[23:48:15] <trentster> I initially planned to build one, but this was way less effort

[23:49:18] <trentster> Wolf_: wow I havent seen one of those genius mouse pads in 20 years ;-)
[23:49:48] <Wolf_> trentster: first google image that was what I was looking for

[23:50:15] <XXCoder> nah dont know what they are in usd thats all lol
[23:50:22] <codepython777> Wolf_: I have the cyclone + the brush head - which vacuum do we get ?
[23:50:23] <XXCoder> that one isnt bad
[23:50:29] <XXCoder> weak reviews though
[23:50:57] <trentster> XXCoder: dont get that one it sucks, must get the one with the contoured cone at the top, makes a huge diff to the air direction
[23:51:17] <XXCoder> dust deputy?
[23:51:55] <XXCoder> oneida is very expensive
[23:52:03] <codepython777> XXCoder: any recommendation for the vacuum to get for the cyclone?
[23:52:23] <XXCoder> shopvac will do. bigger one not tiny one
[23:52:31] <Wolf_> pick a shop vac, IMO get something with common filters
[23:52:43] <XXCoder> though my older metal bucket small one could do it, its powerful for its size
[23:52:44] <trentster> XXCoder: anyone that looks like this will do

[23:52:52] <XXCoder> its 50 years old my guess

[23:53:14] <trentster> as far as the vacuum, you can use any vacuum with it as almost zero dust gets to the vacuum, I use a little cheapie
[23:53:34] <XXCoder> trentster: though want more power for alum clearing I guess
[23:53:49] <codepython777> trentster: I want to get one, that is a powerful sucker
[23:54:02] <trentster> XXCoder: you will be amazed how much power a little vacume connected to a cyclone has.
[23:54:10] <XXCoder> thanks trent
[23:54:15] <trentster> I cut tons of aluminium on my machine, no issue
[23:54:33] <XXCoder> hmm cool
[23:54:40] <codepython777> trentster: Is it possible to pull out every chip from the spindle using a vacuum?
[23:54:53] <XXCoder> I do want to get vacuum system evenually as my router runs in downstairs living room once its actually functional :P
[23:55:12] <trentster> codepython777: with a dust hood over your spindle?
[23:55:18] <trentster> or holding it by hand?
[23:55:46] <codepython777> trentster:
http://hamrx8.com/images/CNC%20Router%20Dust%20Extractor_05.JPG - with this?
[23:55:47] <XXCoder> so far all ones that have that contour is over $100 lol
[23:56:32] <trentster> codepython777: yes should be fine all depends on the efficiency and airflow of the dust shoe design.
[23:56:40] <XXCoder> finally found $50 usd one
[23:57:06] <trentster> I assume you are using a proper spindle + fvd and not a wood router like dewalt etc...right?
[23:57:20] <Wolf_> codepython777: that shoe I linked was just first one I saw on google that was clear how it worked :P
[23:58:51] <trentster> Wolf_: a picture dooes not tell you how it works…I would be suprised if that design works effectively
[23:59:09] <Wolf_> shows the general idea lol
[23:59:14] <codepython777> Wolf_: does someone sell such a shoe/skirt?
[23:59:20] <Wolf_> I dont use one..
[23:59:29] <trentster> yup,
[23:59:33] <Wolf_> but, I’m also using a mill...
[23:59:53] <codepython777> https://www.omiocnc.com/products/x6-2200.html - this is the one
