[01:35:39] <archivist> ayjay_t, make sure you check the real sensor resolution of the camera, lots of sham 640 pixel junk in the usb microscopes
[01:35:56] <ayjay_t> yeah archivist, i found a lot of junk and ended up not making a decision
[01:36:19] <ayjay_t> i'm not really sure how to compare cameras on a technical level, i was looking at mp because reviews are clearly bogus
[01:36:41] <ayjay_t> and a lot of the cameras available are the same thing white labeled and marketed
[01:36:49] <ayjay_t> plus manual focus... meh...
[01:37:11] <miss0r> isn't manual focus exactly what you'd want? :)
[01:37:30] <ayjay_t> i think in *some* situations
[01:37:52] <miss0r> well, if you can switch it on and off that would be good then
[01:37:55] <ayjay_t> i actually want something for inspection but also something general person, one of the engineers here is visually impaired
[01:38:18] <ayjay_t> general purpose* its late
[01:39:02] <miss0r> I got the meaning :) This is what I love about IRC. I just got up 1 hour ago, and to some it is late
[01:39:54] <Wolf_> imo, manual focus works fine, auto focus on something with a 1mm depth of field would drive me crazy
[01:40:22] <miss0r> but early is also an excuse: I boiled the water for coffee, forgot about it. boiled it again and forgot the coffee all together. now I am here
[01:40:43] <ayjay_t> haha
[01:41:49] <ayjay_t> yeah i guess we're gonna go with manual focus
[01:41:55] <ayjay_t> i'm a little concerned with linux compatibility too
[01:41:58] <Wolf_> major fail with most of the usb microscope cams are the bases they come with, makes them unusable, mounting it on a indicator base would probable work well
[01:42:12] <miss0r> also, i forgot my breakfast on the kitchen table. I guess its just one of thoes mornings. This is a bi-product of having a 11 month old kid, not sleeping well at night
[01:42:21] <Wolf_> probably even…
[01:42:32] <Wolf_> 2am here, its early lol
[01:42:55] <archivist> getting breakfast while IRCing here
[01:42:58] <miss0r> here its 8 (in the morning) Can never remember the AM/PM stuff
[01:43:42] <Wolf_> 14:00 would be pm
[01:43:46] <ayjay_t> yeah i'm EST too
[01:44:22] <miss0r> and 8 would be AM then?
[01:44:47] <Wolf_> yeah, just think of PM = plus 12 lol
[01:45:05] <miss0r> I seem to remember using AM as After Midnight
[01:45:07] <Wolf_> 8pm = 20:00
[01:45:16] <Wolf_> that too
[01:45:24] <archivist> ayjay_t, most of the time I use a stereo zoom microscope
[01:46:08] <ayjay_t> eventually...
[01:47:50] <Wolf_> does linux work with generic web cams?
[01:47:57] <miss0r> yes
[01:48:05] <miss0r> They are very well supported
[01:48:20] <ayjay_t> some of these usb microscopes come with cds tho >_> <_<
[01:48:58] <miss0r> because its cheaper to write CD than it is to print a manual
[01:48:59] <Wolf_> I think most of the usb microscopes come up as generic web cams, mine came with windows software but on my mac I am stuck using it with photobooth lol
[01:49:00] <archivist> often it is just a standard webcam they use anyway
[01:49:40] <SpeedEvil> http://www.ebay.com/itm/8-LEDs-2MP-500x-USB-Digital-Microscope-Video-Webcam-Magnifier-Camera-Stand-Loupe-/401017903087?hash=item5d5e8797ef:g:vo8AAOSwTA9X9etG I got
[01:49:44] <SpeedEvil> the base is truly excellent
[01:49:45] <miss0r> hopefully one with a bit more pixels than 480 across :)
[01:50:32] <SpeedEvil> Also, actual legit pixel numbers, which is nice
[01:50:43] <miss0r> SpeedEvil: That is realy cheap. Hows the picture on this one?
[01:50:45] <Wolf_> http://i.imgur.com/v9xEFaj.jpg cheap usb scope
[01:50:54] <SpeedEvil> miss0r: pretty good.
[01:51:09] <archivist> http://www.ebay.co.uk/itm/NEW-5-0MP-HD-Digital-C-mount-Microscope-Camera-USB-Output-with-100x-zoom-lens-/112020148822
[01:51:16] <Wolf_> and
http://i.imgur.com/lT9fy7F.jpg
[01:51:19] <SpeedEvil> miss0r: I would here insert a picture, but I don't have the device to hand
[01:51:56] <ayjay_t> if the 5mp one is legit...
[01:51:57] <SpeedEvil> From memory, it goes down to about 0.5mm or so minimal field width, and is reasonably sharp at that.
[01:51:57] <archivist> 2592 across
[01:52:15] <miss0r> I wish I had a use for a microscope :)
[01:52:30] <ayjay_t> but archivist that microscope... how do you focus it
[01:52:31] <SpeedEvil> miss0r: watching paint dry
[01:52:38] <ayjay_t> its in a *box*
[01:52:51] <archivist> mount on something
[01:52:55] <ayjay_t> oh my god it comes iwth a huge lens
[01:53:03] <ayjay_t> i was blind to that gigantic teloscope
[01:53:05] <Wolf_> mine, 4yrs old
http://a.co/aKSfATy
[01:53:07] <ayjay_t> telescope*
[01:53:17] <archivist> that is a separate proper camera +zoom
[01:54:01] <ayjay_t> 100X on display it is
[01:54:04] <SpeedEvil> miss0r: I've used it for many things, from threading needles to precision embroidery to soldering, to ...
[01:54:16] <miss0r> SpeedEvil: That is my brothers job. I kid you not. He is a chemical engineer, working for a paint company, doing analazys on epoxy paint.
[01:54:17] <ayjay_t> scope is only 2X
[01:54:24] <ayjay_t> i'm interested though
[01:54:34] <SpeedEvil> excellent for analysing circuits
[01:55:28] <ayjay_t> meh i'm gonna buy speedevils and archivists
[01:55:43] <SpeedEvil> there is noticable display lag.
[01:55:43] <ayjay_t> *dollar dollar bills*
[01:55:50] <SpeedEvil> ~.2s or so
[01:55:55] <SpeedEvil> maybe a bit less
[01:55:55] <miss0r> the circuits I make, a magnifying glass with a lamp in it is quite sufficient. :) I hardly ever make smaller pads than 0.33x0.33mm
[01:56:14] <ayjay_t> so not enough to make you wanna throw it out
[01:56:15] <SpeedEvil> Also used for self-surgery
[01:56:18] <ayjay_t> but *noticable*
[01:56:51] <archivist> ayjay_t, note space/distance under
http://www.collection.archivist.info/archive/DJCPD/PD/2014/2014_09_07_Lorch_lathe/IMG_1823.JPG
[01:56:58] <Wolf_> oh, SpeedEvil has the one that does not come with a total POS base
[01:57:43] <archivist> get both make one out of two(base/camera)
[01:58:07] <ayjay_t> haha archivist, i'm not sure what to look for
[01:58:14] <ayjay_t> i realize a stereoscope is better, but my office is *cramped*
[01:58:28] <ayjay_t> like we've turned *everything* into shelf space
[01:59:16] <archivist> I understand the space problem, I bring anything small to the lathe to look at it
[02:00:32] <Wolf_> space is always a issue… I need a bigger shop
[02:00:38] <archivist> I also found
http://www.ebay.co.uk/itm/3-5-LCD-500X-Desktop-Digital-MicroScope-5MP-HD-USB-TV-Camera-Video-Recorder-UK-/331808669825
[02:13:59] <miss0r> This lathe is turning out to be a real pain to put back together
[02:16:40] <Deejay> moin
[02:42:41] <gonzo_> was that a pun?
[02:57:16] <miss0r> ain't nothing like shimming a lathe gearbox with steel wire.
[03:42:03] <miss0r> I think removing old sealing from cast iron.
[03:42:12] <miss0r> just made it to my top 5 of stuff I hate
[03:42:42] <archivist> scraper makes it quick and easy
[03:43:01] <SpeedEvil> Just heat to 300C
[03:43:24] * SpeedEvil tries to remember that book.
[03:43:32] <SpeedEvil> Fundamentals of machine accuracy?
[03:44:03] <SpeedEvil> They reported that they got their precision measuring machines back after having been in a fire, with all the paint completely burned off, and measured them, and they were still dead on.
[03:44:10] <SpeedEvil> (the cast iron parts of course)
[03:44:21] <miss0r> good question. I'm using a scraper. but this old paper sealing is realy set on staying
[03:44:43] <miss0r> :o that us some scary stuff
[03:44:43] <Valen> if they weren't rusted to crap I'm guessing they probably didn't actually get that hot
[03:45:11] <miss0r> Valen: what difference will the rust make?
[03:45:34] <miss0r> I know I said sealing, but it is realy a paper gasket
[03:45:35] <Valen> I'm guessing at least a micron
[03:45:51] <miss0r> Valen: with the tempeture I mean?
[03:45:58] <Valen> I was saying the ones in the fire, iron rusts pretty quick in a fire
[03:46:04] <SpeedEvil> cast iron
[03:46:07] <miss0r> ahh inded
[03:46:13] <SpeedEvil> cast iron and regular iron are very different
[03:46:18] <SpeedEvil> (or steel)
[03:48:45] <miss0r> What is the english technical term for an oiling distribution system that basically just throws oil ramdomly around inside an enclosement, using a paddlewheel
[03:49:10] <miss0r> I know the danish word for it, but it doesn't translate well :)
[03:49:11] <Valen> splash oiling?
[03:49:19] <Valen> don't know if that's right
[03:52:27] <miss0r> I don't know either. perhaps something with the word 'centrifugal' in it?
[03:53:47] <SpeedEvil> splash oiler
[03:54:30] <miss0r> I guess that is the correct term. I have a Landrover with an external splash oiler. Keeps the chassis nice and rust free
[04:02:16] <miss0r> archivist: I just ordered the small surface grinder. I hope it will do well
[04:09:44] <archivist> grmbl....I WANT ONE
[04:09:49] <archivist> :)
[04:10:16] <miss0r> if you were faster, you could have made an offer for my jacobsen SJ16 ;)
[04:10:33] <archivist> I have no money!
[04:10:33] <miss0r> if you had 5M^2 floorspace you didn't know what to do with
[04:10:53] <archivist> been collecting ideas and made one
http://www.collection.archivist.info/searchv13.php?searchstr=tool+grinder
[04:11:13] <SpeedEvil> Brother made a 'surface grinder'
[04:11:27] <SpeedEvil> which he used to level the surface of ceramic wavy tiles
[04:11:31] <SpeedEvil> worked great
[04:11:45] <miss0r> then you do have one :)
[04:11:47] <SpeedEvil> angle grinder + diamond disk + chopping board bearings
[04:11:51] <miss0r> i'm the one who realy needs it
[04:12:11] <miss0r> SpeedEvil: Yeah, no reason to over complicate things :D
[04:12:14] <archivist> I needed to make a cutter for bevel gear
[04:14:04] <archivist> a quorn tool and cutter grinder would be nice
[04:14:04] <miss0r> I've always just milled my gears
[04:14:28] <miss0r> in the CNC
[04:14:37] <archivist> bevels are a bit nasty for a good fit
[04:14:41] <miss0r> It takes forever, but it gets the job done
[04:14:53] <miss0r> I made one a few years back, still runs.
[04:16:06] <archivist> the maths for gleason bevel gear generation using "rack" style cutter
http://www.archivist.info/gear/designbevel.php
[04:18:03] <miss0r> The spare I made:
http://picpaste.com/20161116_104722-P2oRTWJN.jpg
[04:18:53] <archivist> I can see facets :)
[04:19:22] <miss0r> yeah. but it works nontheless
[04:19:30] <archivist> 5 passes by the look of it
[04:20:36] <miss0r> that was the first bewel gear I ever cut. it was in the CNC for 5 hours LOL
[04:21:33] <archivist> http://www.collection.archivist.info/searchv13.php?searchstr=bevel the setup and result (angle wrong)
[04:21:59] <archivist> nice involute curve and taper though
[04:23:24] <archivist> bad angle probably from backlash in the rotary and root too narrow
[04:24:41] <miss0r> I must admit not haven been scientific enough about this job :) but the one I installed works like a charm.
[04:26:03] <archivist> I was experimenting for a customer, and he complained about me using steel, I dropped work at that
[04:26:33] <archivist> cheeky bugger
[04:27:03] <miss0r> why would that be a problem?
[04:28:14] <archivist> I cannot see why steel would be a problem for him, stronger for him, cheaper for me to experiment with
[04:29:01] <archivist> I was also running the cnc for 5 hours ish
[04:38:34] <SpeedEvil> Gears are easy, you just cut square teeth, mesh them, and then run with finer and finer grades of abrasive.
[05:03:56] <miss0r> lathe gearbox cover plate is back in place... another thing to add to my top five: Getting all the handles alaigned with their respective gears, when putting the lid back on this lathe
[05:06:52] <miss0r> also, for whatever reason, the drainage plug in the chip tray, which all the oil from the gearbox lands in, is 5 mm higher than the rest of the chip tray. *sigh*
[05:07:30] <sync> Add wood chips
[05:08:01] <miss0r> yeah. i'll do that
[05:08:07] <XXCoder> possibly to keep heavy chips there and not blocking drain?
[05:10:13] <miss0r> if it is realy the case, you'd have a permanent stew laying around down there
[05:10:23] <XXCoder> yummy
[05:12:22] <miss0r> luckily I hardly ever use coolant on my lathe. and when I do, I use a mister
[05:14:18] <XXCoder> not abd
[05:14:19] <XXCoder> bad
[05:19:19] <miss0r> the wife is gonna kill me. I got oil on my new pants :)
[05:20:20] <XXCoder> tell her new pants need oiling to work smoothly
[05:37:48] <miss0r> yay ! clutch is working
[05:39:15] <SpeedEvil> :)
[05:41:07] <archivist> another happy bunny
[05:42:25] <miss0r> not flawlessly thou. It will always transfere some tourque, no matter what. and that can cause issues with gear change while motor is running. it does not have the power to plin the chuck while disengaged, BUT, if you move the first gear set, and have it between gears for more than 0.5 seconds, they will spin up
[05:43:26] <miss0r> but i'm calling it a success nonetheless
[05:44:22] <miss0r> archivist: I can't seem to remember. You are from the UK, right?
[05:44:45] <archivist> yes
[05:45:10] <miss0r> what is going to happen to all the import/export with europe, with brexit'n all
[05:45:19] <miss0r> I do some pretty good ebay buys from there
[05:45:30] <archivist> 30 miles noth of Craddocks landrover shop
[05:46:05] <miss0r> craddocks? I only know paddocks spares
[05:46:24] <miss0r> is it a wordplay involving crap and paddocks? :)
[05:47:05] <archivist> no you first asked about landrover spares in #classiccmp
[05:47:32] <miss0r> did I? :S That must be a long time ago
[05:47:53] <miss0r> My poor old landrover have been sitting idle for years now :-/
[05:48:54] <archivist> Icanhasreasonablememory
http://www.johncraddockltd.co.uk/
[05:48:55] <miss0r> I just recieved the invoice for the surface grinder...
[05:49:33] <miss0r> I can't recall ever actualy buying anyting from there. most the stuff I ordered was from paddocks
[05:49:34] <archivist> delivery charges double the price?
[05:50:04] <miss0r> no. Quite reasonable price for shipping. ~250eur
[05:52:43] <archivist> bah, log on this box does not go far back enough
[05:55:10] <miss0r> I guess i'll have to take your word for it ;)
[05:55:16] <Tom_L> how far back do you want?
[05:56:03] <archivist> Tom_L, was in another channel
[05:56:10] <Tom_L> ahh
[05:57:31] <miss0r> I was thinking about driving up there and picking up the grinder myself. But for that price, I can hardly pay for bridge fee and gas. Not to mention all the time I'd have to spend
[05:59:11] <archivist> seems I have it in the mysql log though 2011-04-29 14:42:51
[06:00:09] <miss0r> you sure do live up to your name ;)
[06:00:29] <jthornton> morning
[06:00:36] <miss0r> mornin'
[06:00:51] <archivist> just have to dream up the sql to get the actual messages
[06:02:23] <miss0r> Time to order A pizze to celebrate blowing money on a surface grinder...
[06:05:03] <archivist> miss0r, my memory was right(channel) and yours was right(paddocks)
[06:05:29] <XXCoder> wonder what was first thing I said this channel :P
[06:05:46] <miss0r> the crazy part is; My memory isn't worth a damn :)
[06:06:06] <miss0r> archivist: yeah, can you stirr up our first comment in this channel?
[06:08:11] <archivist> #linuxcnc | miss0r | 2014-03-02 16:09:41 | joined chan |
[06:08:25] <miss0r> that doesn't realy count ;)
[06:09:04] <XXCoder> lol
[06:09:08] <archivist> actually the following lines might mean I have pruned some data
[06:09:29] <archivist> #linuxcnc | miss0r | 2014-03-02 16:11:42 | I got 43434 with the 1ms and 21586 with the 25us
[06:09:40] <archivist> odd for a first statement
[06:10:01] <XXCoder> yeah
[06:10:04] <XXCoder> so whats mine heh
[06:10:10] <archivist> or bot dropped out or a netsplit
[06:10:11] <miss0r> that realy is an odd first statement. That is absolutly about me configuering linuxcnc the first time.
[06:11:04] <archivist> #linuxcnc | XXCoder | 2014-03-15 18:17:34 | curious on what linuxcnc can do
[06:11:33] <XXCoder> well that is pretty reasonable for first time heh
[06:12:17] <miss0r> it is.. brb, need to go pick up pizza
[06:14:03] <archivist> miss0r, we started talking in another chan and continued in here
[06:16:09] <malcom2073_> archivist: What about me?
[06:19:28] <archivist> malcom2073 | 2013-10-03 14:19:31 | Heh, when you have a hammer
[06:19:43] <malcom2073_> nice
[06:20:59] <miss0r> archivist: Funny, on the car ride to get the pizza and back, I remembered what you just said :)
[06:22:36] <archivist> I think I joined this channel in about 2006
[06:23:41] <archivist> or more like 2008 looking at image dates
[06:25:06] <miss0r> thats is a fair amount of time :)
[07:05:46] <miss0r> A wonderfull thing about buying stuff from sweden to denmark, is I don't have to pay taxes of the purchase :)
[07:10:47] <miss0r> DaViruz: There we go. I have now bought the surface grinder. Thanks for the tip
[07:16:39] <jthornton> I bought a surface grinder from Arkansas and they had the rollers in wrong so the table was tilted... got it cheap
[07:17:28] <miss0r> sounds like a good deal :)
[07:18:06] <jthornton> yea, got it home and had to replace the metering valves and put the rollers in the correct way and been a good grinder ever since
[07:18:28] <XXCoder> gonna love badly repaired but not unfixable stuff
[07:24:50] <MrTrick> Learning G-code generation, having this interpreter reject the arc as "the target of the arc is invalid"
[07:24:50] <MrTrick> https://gist.github.com/MrTrick/6f4cae38a665a61b26b6fdd72eda85a1
[07:25:04] <MrTrick> Any idea why?
[07:25:07] <tiwake> XXCoder: should I get another project vehicle?
[07:25:28] <XXCoder> if you have incomplete one nope lol
[07:25:43] <miss0r> hehe
[07:25:44] <MrTrick> (preceding it is G54 G17 G21 G90 and G92 X0 Y0 Z0 S0)
[07:25:58] <XXCoder> i once met one guy with unfinished project vehicle lot that looked like car store of incomplete cars :P
[07:26:01] <tiwake> XXCoder: well, my mustang is functioning... but the clutch is starting to slip
[07:26:13] <miss0r> tiwake: I have a 1972 88" 2.25l petrol landrover project that is 9+% complete. you can have it for next to nuttin'
[07:26:26] <miss0r> 90*
[07:26:56] <archivist> or project for retirement
[07:27:07] <tiwake> XXCoder: the other project truck I am considering is a 2008 F150 that is in good condition except for the engine that was ran without oil
[07:27:18] <tiwake> and cheapish
[07:27:32] <tiwake> bluebook is ~5,000 for it, if the engine worked correctly
[07:27:33] <miss0r> archivist: i'm 40 years from retirement, unless I win the lottery. In that case I am only 40 sec. away
[07:27:59] <miss0r> Note to self: Start playing the lottery
[07:28:14] <tiwake> so "project vehicle" would just be an engine... possibly rebuilding an engine and dropping it in
[07:28:35] <tiwake> which is a lot (lot) less work than my mustang needs
[07:28:39] <XXCoder> remember car project is like highlander... there can be only one. ;)
[07:28:58] <archivist> buying more than one so you have spares makes sense
[07:29:18] <tiwake> the engine thats in it is the same engine currently in my mustang
[07:29:34] <archivist> there are no project limits, only space limits
[07:29:37] <tiwake> donno... I keep talking myself into it and out of it
[07:29:54] <XXCoder> https://www.youtube.com/watch?v=1G13KzEJqBw I want that ship :P
[07:30:15] <MrTrick> aha - IJK were incremental. Every line was meant to be J-25
[07:31:07] <tiwake> where can I find useful information for mixing and matching parts?
[07:31:20] <tiwake> to know if they will fit in and work correctly
[07:31:46] <tiwake> I know a 5.4 engine will drop in no problem, but what about the transmission?
[07:37:38] <tiwake> not sure what the difference is for coil on plug and coil packs
[07:37:51] <tiwake> in terms of wiring... engine harness is different obviously
[07:38:34] <tiwake> meh
[07:38:52] <tiwake> I'm also starting to realize any car/truck/whatever can be turned into a project
[07:39:23] <tiwake> "lets make this not suck..." *bam* project
[07:39:44] <tiwake> which is all vehicles that exist
[07:49:38] <Tom_L> some could take a lifetime to 'make this not suck'
[08:01:02] <jthornton> Tom_L: getting close

[08:01:20] <jthornton> now to build a years worth like the other template I showed you
[08:01:42] <jthornton> shower time
[09:41:31] <CaptHindsight> gregcnc:
http://chicago.craigslist.org/nwc/for/5873119315.html he can't make up his mind on the price, $1k, then $4k now $3k
[09:41:40] <gregcnc> https://chicago.craigslist.org/sox/for/5878462846.html
[09:42:09] <gregcnc> i'd guess someone told them it's worth far more than 1k
[09:58:56] <MacGalempsy> hey guys
[10:09:06] <IchGucksLive> hi
[10:09:11] <IchGucksLive> raining here in germany
[10:10:22] <IchGucksLive> till ....
[10:12:50] <MacGalempsy> no rain here in Arkansas
[10:13:31] <MacGalempsy> sunny and a good day to work on the printer
[10:36:19] <HoloPed> Can someone recommend software that can generate gcode from vector, for a laser cutter? I'm currently using CamBAM which works but it's designed for laser and the output is not optimal. My files are very big (80,000 curves) so stuff like LaserWeb or InkScape plugins just crash.
[10:43:27] <CaptHindsight> http://www.scan2cad.com/ not free
[10:48:14] <HoloPed> CaptHindsight, that doesn't generate gcode
[10:48:22] <HoloPed> or does it ?
[10:50:48] <CaptHindsight> HoloPed: sorry, my mistake
[11:08:39] <CaptHindsight> HoloPed:
http://www.scan2cad.com/tips/scan2cad-in-cam/ now this says the latest version does generate g-code
[11:11:57] <CaptHindsight> misleading article "directly export vector images to a G-code compatible format."
[11:37:08] <FloppyDisk525> two suggestions that might not be helpful. 1. break up the large vector (however that might be done) into smaller chunks. Maybe there are layers that can be done separately?? 2. Solidworks, Autodesk inventor, etc CAD program if it can open vector (Sla?) and then hsmworks, Camworks, etc. But, you might have the same issue as CamBam -> Not optimized for laser?
[11:38:24] <FloppyDisk525> I wonder how a sheetmetal shop w/ a large Amada laser would do this? The sheetmetal shops I have seen use Solidworks and one of those CAM programs, but actually, not sure.
[11:39:32] <CaptHindsight> they probably have mastercam and other applications
[11:40:38] <CaptHindsight> http://www.amada.com/america/software-ap100us
[11:41:21] <roycroft> i just got a 3d mouse yesterday
[11:41:31] <roycroft> my productivity with solidworks has gone up by at least 50% already
[11:41:37] <roycroft> why did i not get one years ago?
[11:52:25] <FloppyDisk525> roycroft - that's awesome. I worked w/ some SWs cad guys who resisted them and I never understood why.
[11:52:49] <FloppyDisk525> They were good technicians, but little things like that scared them or something...
[11:57:06] <roycroft> the thing just makes so much sense
[11:57:23] <roycroft> i should add that i do my solidworks stuff on my laptop, as it's actually more powerful than my main workstation these days
[11:57:34] <roycroft> so i'm using a trackpad, which makes zooming/panning very difficult
[11:57:56] <roycroft> but even if i were using a "normal" mouse i'd be working a lot more efficiently with the 3d mouse
[11:58:48] <roycroft> they're expensive, which is probably one reason i haven't paid much attention to them heretofore, but i found a good del on ebay
[11:58:50] <roycroft> deal
[11:59:03] <roycroft> a 3dconnextion spacenavigator for $50
[11:59:15] <roycroft> that was cheap enough for me to give it a go
[11:59:59] <roycroft> i'm not sure if i'll upgrade to the fancier ones with a buttload of programmable buttons - the spacenavigator comes with 2 programmable buttons and i haven't done anything with those yet
[12:00:13] <roycroft> i'm just using it for pan/zoom/rotate right now
[12:03:12] <_methods> yeah we use the trump software for our laser, trutops
[12:03:49] <_methods> but i've use metamation, sigmanest, pronest, and dr abe which was amada's looks like theyve changed the name to that ap100s or whatever
[12:04:06] <_methods> metamation is by far the best nesting/pathing software package out there
[12:04:13] <_methods> followed by sigmanest
[12:04:58] <_methods> the good thing about metamation is that you don't even need a dxf to path you can pull your solid model right from solidworks and it will work with that
[12:05:49] <CaptHindsight> _methods: does the software change it's output every time you click generate g-code? :)
[12:07:01] <_methods> not if you don't change your model
[12:18:01] <enleth> does it make sense to connect a transil diode and a high-wattage resistor across a DC servo to protect the servo drive from momentary high volatage spikes when running in torque mode?
[12:24:04] <pcw_home> How would you get a HV spike? ( any voltage < VBUS- or >VBUS+ will be shunted by the power supply)
[12:26:29] <pcw_home> sometimes DC drives have a small capacitor (say 1000 PF) across the motor leads to limit extremely fast rate of rise spikes from armature arcing
[12:29:29] <IchGucksLive> hi
[12:34:35] <IchGucksLive> i will start a new series of Tutorials Vid on Youtube as so many are asking on the New System
[12:34:51] <IchGucksLive> German and english
[12:35:29] <IchGucksLive> problem as always it to change the menue language
[12:36:17] <CaptHindsight> I hope Rouladen is on the menu :)
[12:37:08] <IchGucksLive> with Blaukraut of cause
[12:43:33] <IchGucksLive> i need to restart for the english tutorial
[12:45:01] <Jymmm> Just wait till he finds out it's an ancient Chinese dialect tutorial instead =)
[12:47:30] <enleth> pcw_home: as far as I understand, an excessively rapid setpoint reversal in current mode might cause the motor armature inductance to generate a substantial voltage spike, trying to prevent the sudden change in current
[12:47:56] <pcw_home> Not an issue
[12:49:25] <pcw_home> imagine the fastest current change possible (disable all driving MOSFETS on a fault for example)
[12:49:52] <IchGucksLive> back
[12:50:49] <Jymmm> pcw_home: "A woman changing her mind?"
[12:51:47] <pcw_home> any armature voltage > motor power supply voltage is simple shunted by freewheeling diodes (or MOSFET bulk diodes)
[12:51:48] <pcw_home> back into the motor power supply, limiting the maximum spike voltage to the motor power supply voltage + 2 diode drops
[12:52:10] <Jymmm> Is most test lead wire considered "high voltage" rated ?
[12:52:54] <pcw_home> unless its chinese cheeze style insulation material
[12:53:24] <pcw_home> also known as"twist to short"
[12:53:57] <Jymmm> Hmmm, maybe I can sacrafice a mueler test lead
[12:54:44] <Jymmm> Would THHN be a big no no?
[12:54:57] <Jymmm> I got craploads of 12ga
[12:55:01] <enleth> pcw_home: *any* armature voltage?
[12:55:17] <pcw_home> yes
[12:56:37] <pcw_home> any voltage across the hbridge outputs > hbridge power supply voltage simply feeds back into the power supply
[12:57:32] <pcw_home> ( which is why you want a large filter capacitor on the motor power supply )
[12:57:56] <enleth> well, yes, I meant voltages in excess of what the MOSFET diodes can handle
[12:58:29] <pcw_home> the MOSFET dides are forward biased in this case
[12:58:35] <pcw_home> diodes
[12:58:48] <pcw_home> so PIV is not an issue
[13:00:03] <pcw_home> consider that the drive must have a deadzone (top and bottom MOSFETS off) when switching to prevent shoot-through
[13:01:30] <IchGucksLive> i finishe the EN toutrorial but had the mike not pluged
[13:01:34] <IchGucksLive> what a mess
[13:02:06] <pcw_home> at this point you will get an inductive spike as the armature is open circuited for a period of time
[13:02:07] <pcw_home> This is clamped by the free-wheeling diodes or MOSFET bulk diodes so the voltage cannot exceed
[13:02:09] <pcw_home> the motor power supply voltage
[13:02:42] <enleth> pcw_home: well, OK, I may have found some non-existent problem trying to figure out all cases on a whiteboard
[13:04:53] <Jymmm> Those look sexy...
http://usedstainlesssteelbarrels.com/shop/stainless-steel-barrels/30-gal-304-used-stainless-open-head-barrel-1-51-21-2mm/
[13:05:09] <pcw_home> just consider that because of the dead zone you are getting maximum di/dt at twice the PWM rate!
[13:05:41] <enleth> pcw_home: right
[13:06:09] <roycroft> those barrels are expensive
[13:06:17] <roycroft> you should be able to find them for half that price
[13:07:28] <enleth> so far I've figured out the capacitance required on the DC bus by working backwards from the typical kinetic energy stored in the machine's moving armature in an emergency stop situation
[13:12:07] <IchGucksLive> changig language back
[13:14:10] <IchGucksLive> Back on german
[13:14:29] <pcw_home> enleth: thats probably not at all economic, this is normally handled by a brake resistor and circuit
[13:15:28] <pcw_home> (the shunts the power supply)
[13:15:35] <pcw_home> that shunts
[13:15:58] <enleth> pcw_home: I'm looking for a suitable brake resistor on auction sites too
[13:16:16] <pcw_home> a stove element works well
[13:16:48] <enleth> I'm inclined to start testing with a 600W travel electric kettle, the resistance is just about right
[13:17:31] <pcw_home> just need to write the "make tea" gcode
[13:17:58] <enleth> AFAIR someone here did use a kettle for a brake resistor
[13:18:49] <IchGucksLive> someone please can check sound ok
https://youtu.be/xixQNJznJTc
[13:19:30] <enleth> as for DC bus capacitance, I just happened to have a bunch of capacitors that added up to a sufficient capacitance, rated for double the normal bus voltage
[13:21:32] <enleth> came from the input stage of a dead 48V power supply, out of the batch I ordered to power the servos
[13:21:47] <SpeedEvil> Do test ESR if old
[13:21:56] <SpeedEvil> I found some 2 ohm ESR coke-can caps
[13:22:11] <SpeedEvil> 150000uF, 20V, 2R
[13:22:20] <enleth> they seem to be fine
[13:25:24] <enleth> FWIW, they're even brand name
[13:32:03] <IchGucksLive> pcw_home: got more then one tea g-code ;-)
http://pasteall.org/pic/index.php?id=108831
[13:32:20] <IchGucksLive> Deejay: ?
[13:32:27] <IchGucksLive> nubcake: ?
[13:33:19] <IchGucksLive> enleth: make shure they unload after poweroff
[13:33:26] <IchGucksLive> you can kill someone
[13:34:10] <IchGucksLive> someone here can please check if the sound of the new Vid totorial is ok
[13:38:34] <IchGucksLive> im off Gn8
[13:47:02] <archivist> cheap castings
http://www.ebay.co.uk/itm/252638930013
[13:50:40] <miss0r> you know the feeling, where you bought a new peice of equipment, but can't realy seem to figure out where to put it in the shop?
[13:51:31] <DaViruz> a friend of mine says that before you buy anything you should have a clear picture of where it will live, no matter how small
[13:51:55] <DaViruz> he fully admits he doesn't practice it, but it's fairly good advice
[13:52:06] <miss0r> it is. :)
[13:52:14] <miss0r> I bought that surface grinder. thanks for the tip
[13:52:34] <DaViruz> cool!
[13:53:12] <miss0r> it will ship tomorrow with schenker. I have no idea what their delivery time is thou
[13:53:47] <DaViruz> within sweden usually overnight
[13:54:14] <miss0r> that sounds pretty good. Then I might have it friday if all goes well
[13:54:51] <miss0r> but not realy anywhere to put it. I will have to move some stuff around, and see where that puts me
[13:55:22] <archivist> shed extension building time
[13:55:52] <archivist> seems common in here
[13:56:13] <miss0r> archivist: i've mentioned the idea to the misses. But we aren't quite on the same page on that project
[13:56:49] <miss0r> FUCK! a new mouse is not roaming the attic in here !
[13:56:55] <miss0r> not=now
[13:57:11] <miss0r> will they stop at nothing ?!
[13:57:17] <cradek> haha the misses
[13:58:22] <miss0r> I have my man cave in the basement, and my shop in the garage. If I do anything outside of these I have to clear it with the misses
[13:58:38] <gregcnc> mine is pissed that I have that much
[13:59:01] <miss0r> I think mine has accepted her fate. :]
[13:59:58] <archivist> give her the cave and grab the garden for shed
[13:59:59] <cradek> I was laughing because you are misspelling missus in a way that reads as the plural of miss
[14:00:26] <cradek> I was imagining you giving a presentation to all the misses trying to convince them, and then they'd vote or something
[14:01:00] <miss0r> holy! :) One can generate more than enough problems for me. I don't need a flock to gang up on me.
[14:01:08] <cradek> sorry I'll just go back to what I was doing now
[14:01:08] <miss0r> so the correct way is 'missus' ?
[14:01:15] <cradek> yes I think so
[14:01:56] <miss0r> The dictionary concurs with you
[14:02:04] <gregcnc> mrs miss0r?
[14:02:10] <CaptHindsight> misses the missus?
[14:02:35] <cradek> this will all be fixed in English 2.0
[14:02:43] <skunkworks> https://www.youtube.com/watch?time_continue=4&v=gDXWo70xVwA
[14:02:49] <miss0r> This has taken a turn for the worse. I will get back to pulling out what little hair I have left, trying to figure out how to place the surface grinder
[14:03:04] <skunkworks> Just a little older than what we had
[14:03:49] <cradek> SOLID STATE numerical control!
[14:05:01] <CaptHindsight> "Milwaukee-Matic" we should have kept the term
[14:05:48] <gregcnc> i have a couple servo amps with board that look like that
[14:06:36] <CaptHindsight> computer free
[14:08:23] <cradek> can be programmed without the assistance of a computer
[14:08:39] <cradek> (I wonder if they mean a guy doing math for you)
[14:09:00] <miss0r> yeah. i've punched holes in a stripe before. You better need to make hundreds of operations on a single program to make sense :)
[14:10:13] <CaptHindsight> @6:29 for the programming
[14:10:53] <cradek> wow that tool measurer!
[14:11:23] <skunkworks> and simulator..
[14:11:25] <skunkworks> ;)
[14:11:39] <gregcnc> this was magic at the time
[14:11:54] <CaptHindsight> I can't wait for the future
[14:12:44] <cradek> I love how you can just stick the tools wherever
[14:12:54] <gregcnc> yeah how did that work?
[14:13:00] <cradek> a reader
[14:13:02] <CaptHindsight> the controller is bigger than the machine
[14:13:29] <cradek> a stack of rings on the holder that give the tool number
[14:13:50] <gregcnc> ah
[14:13:51] <cradek> ... because then no memory is needed to hold the tool table
[14:14:15] <cradek> just tool number vs. pocket is a lot of bits of memory
[14:29:51] <WZL> Hi, could help me to configure the spindle homing? I cant find an example
[14:31:46] <cradek> I don't think we have spindle homing. what are you trying to do?
[14:32:47] <WZL> an atc that requires spindle orientation
[14:33:20] <cradek> how does it work?
[14:33:52] <WZL> its working right but the angle changes between linuxcnc starts
[14:34:08] <WZL> is like a tap-drill like a robodrill
[14:36:09] <WZL> I need to zero the encoder position of the spindle using de index. in
https://forum.linuxcnc.org/forum/10-advanced-configuration/29567-homing-the-spindle says that ¨To home the spindle you need to set the spindle encoder index-enable pin high, then rotate the spindle past the index.¨
[15:47:35] <kyle___> if anyone's looking for a cheap, tiny drill press, i totally recommend the WEN 8 inch
[15:47:46] <kyle___> this thing is pretty decent for $80
[15:53:28] <lowridah> good to know
[15:53:42] <lowridah> we bought an 8 inch ryobi at work and it's total garbage
[16:05:44] <kyle___> yeah i heard that
[16:05:53] <kyle___> one thing to watch out for is the depth stop collar on these though
[16:05:59] <kyle___> they're plastic and can break pretty easily
[16:06:07] <kyle___> not hard to machine a replacement for though
[16:06:14] <kyle___> it's just two circles, one threaded
[16:06:21] <kyle___> with a nut embedded
[16:11:17] <andypugh> My groceries just arrived. Including a free sample of “Chai Latte” which is apparently “99% Caffeine Free”. I think, even as a coffee lover, I would stter clear of a drink that was 1% caffeine!
[16:13:29] <CaptHindsight> isn't caffeine fatal at doses ~2g
[16:13:59] <pcw_mesa> it is for frogs
[16:14:43] <CaptHindsight> 150-200mg/kg
[16:17:02] <Demure_> I´m having a hard time getting a good surface finish on the sidewalls on my mill (Emco F1) and I'm not sure what the issue is. Looked online and found a few similar finishes by other people, but with no solutions. ( 4.bp.blogspot.com/-w-VtW6BI_3w/UQeWcCMNekI/AAAAAAAABGM/8rBLs3iHarQ/s1600/Finish+A.jpg ) This is the finish Iºm getting on side walls. (Not my picture), usually it's worse. It gets less problematic at 80mm/min, a lot ha
[16:17:10] <andypugh> So, 1.5 litres of 1% caffeine drink would be fatal
[16:17:19] <Demure_> Clickable:
http://4.bp.blogspot.com/-w-VtW6BI_3w/UQeWcCMNekI/AAAAAAAABGM/8rBLs3iHarQ/s1600/Finish+A.jpg
[16:18:04] <andypugh> Demure_: Straigh flutes?
[16:18:08] <andypugh> (straight)
[16:18:10] <Demure_> Checked the nod of the mill: 0.04mm max, X swining less than 0.015, runout less than 0.02, etc. The lines are always perfectly vertical and evenly spaced.
[16:18:35] <Demure_> No, I've used a variety of endmills and get the same result with all.
[16:18:47] <Demure_> Both high helix, carbide, HSS
[16:18:57] <cradek> how deep is the vertical feature you're trying to cut and what diameter of tool?
[16:19:01] <Demure_> Tried almost all possible feeds and speeds combination with a 6mm 4 flute endmill
[16:19:39] <Demure_> Diameter of the tool is usually 6mm, depth of cut Ive tested anywhere between 3 and 10mm, axial depth of cut between 0.3 and 1mm.
[16:19:53] <andypugh> what is the pitch of the lines?
[16:20:01] <Demure_> Even going 0.01mm it gets the same result as a 1mm depth of cut with the 6mm endmill.
[16:20:11] <Demure_> Very very fine, I cannot measure it easily
[16:20:17] <cradek> you're cutting on just one side, or both?
[16:20:33] <andypugh> Just wondering if the pitch matches a stepper-step
[16:20:34] <Demure_> One side, tried both climb and conventional but cannot even see the difference.
[16:20:48] <Demure_> The pitch seems to change depending on feedrate it feels
[16:21:18] <XXCoder> too much backlash?
[16:21:25] <Demure_> But hard to tell. I'm sadly currently away on holiday but it troubles my mind so I had to ask for some advice. I can measure it once I come back and attempt to count how many lines within a mm.
[16:21:35] <Demure_> Backlash is 0.08mm.
[16:21:42] <cradek> frankly it looks pretty normal for a tall vertical feature
[16:21:43] <Demure_> On the worst axis.
[16:22:09] <Demure_> The problem is that it also happens on short vertical features, i.e. depth of cuts of only 3mm
[16:22:10] <cradek> where "tall" is about tool dia for hss and 3x tool dia for carbide
[16:22:13] <andypugh> cradek: I wasn’t going to admit it, but I would probably be happy enough with it too.
[16:22:31] <Demure_> I'm reasonably happy with the result you see in the photo
[16:22:42] <Demure_> But thats the result I get at 80mm/min 1800RPM
[16:22:45] <Demure_> Which seems very slow
[16:22:53] <Demure_> Anything faster and it gets worse.
[16:23:16] <cradek> aluminum?
[16:23:19] <Demure_> I mean, it could be that I'm expecting too much or aiming for a too high surface finish, but I have no experience
[16:23:21] <Demure_> Yes, aluminium
[16:23:31] <Demure_> But same in plastic
[16:23:35] <Demure_> Which surprised me.
[16:23:42] <cradek> hmm!
[16:23:45] <Demure_> No chatter noise either
[16:24:03] <Demure_> Machine seems to have zero issues with any of the cuts I tried and hums along peacefully
[16:24:13] <Demure_> But the result is less satisfactory
[16:24:14] <andypugh> 80mm/min is about as fast as I go, but I can only do 1000rpm on my mill.
[16:24:40] <Demure_> And you see these ridges, too?
[16:24:41] <cradek> yeah 1800rpm at 6mm is <100sfm (sorry, inches) and you probably want more like 300
[16:24:51] <cradek> can you crank up the spindle?
[16:24:51] <andypugh> 1800 rpm is a lot slower than you will see on YouTube show-off videos.
[16:24:51] <Demure_> Yeah, that is what I calculated
[16:25:06] <Demure_> But at 300mm//min it's horrid.
[16:25:21] <cradek> no, I mean increase the spindle speed to 5000 or whatever you can
[16:25:22] <Demure_> I watched some videos of others running the same machine with better results, hence why I am wondering. Max speed is sadly 2000RPM.
[16:25:30] <cradek> aw
[16:25:34] <andypugh> (Though when we visited MPM in Wichita I noticed that all their machines were running a lot slower than YouTube too)
[16:25:51] <cradek> can you put in a 3/8 tool instead?
[16:26:00] <cradek> er 10mm or whatever you folks have
[16:26:13] <Demure_> Been there, tried that. Same result at 10mm.
[16:26:16] <cradek> maybe try a 3 flute, they bounce around less
[16:26:37] <cradek> I have no ideas then
[16:26:41] <sync> andypugh: I know plenty of people who run their machines flat out
[16:26:42] <Demure_> Tried my whole array of cutters, 2 flute, 3 flute, 4 flute, hss, carbide, anything between 3mm and 10mm
[16:26:44] <cradek> have a nice mill file?
[16:26:59] <Demure_> I tested with jogs and straight cuts
[16:27:25] <Demure_> Set jog speed and continious movement and hold the keys until the cut is done.
[16:27:57] <bpuk> stepper based machine? are you microstepping
[16:28:04] <Demure_> Yup, 2 times microstepping
[16:28:14] <cradek> wonder if it's stepper steps like andy said
[16:28:21] <Demure_> I'd love it to be
[16:28:22] <bpuk> can you crank the microstepping up?
[16:28:30] <Demure_> I'll give that a try once I get home
[16:28:43] <Demure_> Would the step length variable be of influence here?
[16:28:56] <cradek> step time? nah
[16:29:26] <bpuk> almost certaintly not. The other thing to try would be to remove a stepper and hand crank that axis and see if it still shows up
[16:29:30] <Demure_> So if it's stepper related it would be the microstepping as the only variable?
[16:29:39] <Demure_> Hmm, that's an interesting idea
[16:30:12] <bpuk> could be a clunky motor, a 'interesting' drive *shrug* - hand cranking will tell you if it's mechanical or motor/control related
[16:30:13] <Demure_> What would you recommend for microstepping? 4x?
[16:30:25] <Demure_> Yeah, didn't think about that as a test
[16:30:42] <bpuk> are you running from a parallel port? or a addon card
[16:30:47] <Demure_> (Hence why suggestions are always so useful ;))
[16:30:58] <Demure_> It's a Mesa 5i25 and 7i76 PCI card
[16:31:05] <Demure_> Would be surprised if those are to blame
[16:31:10] <cradek> turn microsteps up all the way then
[16:31:14] <Demure_> Running at 1000000 I believe.
[16:31:28] <Demure_> The max is 512, that seems a tad high
[16:31:29] <bpuk> since it's a mill, 16x or higher then
[16:31:37] <Demure_> Hmm I see, interesting
[16:31:39] <cradek> heh ok maybe not 512
[16:31:46] <Demure_> I would've never thought of putting it that high
[16:31:48] <bpuk> I'm running 16x on a router with 5m/min rapids
[16:31:48] <cradek> but half stepping is unnecessarily rough if you are unlimited on step speed
[16:32:01] <Demure_> Ok, very good to know
[16:32:43] <Demure_> Well, I think I have enough to test and try out when I get back, now at least I have some peace of mind that I have possible solutions
[16:32:51] <bpuk> but please remember, microstepping doesn't improve accuracy - it does improve smoothness
[16:32:56] <bpuk> (usually)
[16:33:00] <cradek> yes that's right
[16:33:08] <Demure_> I have enough accuracy at 2x already so that's not something I need
[16:33:31] <gregcnc> 2 or 5 phase steppers?
[16:33:45] <Demure_> 2 phase, belt driven to the ballscrew with a 2.5 reduction
[16:33:59] <gregcnc> 5mm pitch
[16:34:07] <Demure_> Yup
[16:34:12] <Demure_> You know it ;)
[16:34:17] <Demure_> 3a/3v 240 oz-in with 80v supply
[16:34:38] <Demure_> Nothing high end on the motor case but they worked well on my lathe so I figured why not
[16:35:12] <gregcnc> that's only 6.25 micron/step My Mill 125 is 1.25 micron and still see this kind of stuff
[16:35:45] <Demure_> But is this the result you see at 80mm/min?
[16:36:01] <delinquentme> Hi all. Whats a plunge rate?
[16:36:02] <Demure_> Because this is about the best result I get at those speeds with high spindle speed and 4 flutes.
[16:36:14] <Demure_> Plunge rate is the speed at which you move your endmill straight down into the workpiece
[16:36:22] <gregcnc> I finish at ~4krpm and 300-400mm/min
[16:36:37] <Demure_> I'd be fine with that, or even half since I'm limited to 2000rpm
[16:36:40] <Tom_L> typically 1/2 or 1/3 regular feedrate
[16:36:49] <Demure_> But at 300 or 150mm/min it doesn't look pretty
[16:36:50] <Tom_L> also ramp is similar
[16:37:15] <Demure_> It looks like I roughed it out with a rougher
[16:37:19] <Tom_L> just make sure you have a center cutting endmill
[16:37:33] <Demure_> ^
[16:38:08] <Tom_L> for either operation
[16:38:08] <gregcnc> how is finish on a single axis move? Mine is awesome.
[16:38:18] <Demure_> This is a single axis move.
[16:38:21] <gregcnc> oh
[16:38:22] <Demure_> Nothing complicated
[16:38:25] <Demure_> Just one axis moving
[16:38:29] <Demure_> That's why I'm not so happy
[16:39:08] <Tom_L> what ballscrew pitch?
[16:39:11] <Demure_> Though I have my hopes set for now that it's stepper related, which wouldn't surprise me as the ridges seem perfectly even and perfectly straight
[16:39:14] <Demure_> mm
[16:39:16] <Demure_> 5mm
[16:39:28] <bpuk> Demure_: I occasionally do mould tools at work, even with tiny tiny stepovers, I'm never happy with the finish - post-polish is normal. It's hard to tell how bad that surface is - but it looks suspiciously like a jerky drive, so the first thing to check is the motor. If increasing the microstepping multiplier doesn't help, my next gut call would be sticktion...
[16:39:49] <Demure_> sticktion?
[16:40:31] <bpuk> changing from slow/fast movement usually takes a lot more force than it does to keep moving
[16:40:40] <gregcnc> i just looked at the photo, what is the scale?
[16:41:06] <bpuk> if your slides/dovetails are sticky that could also cause that kind of jerkiness
[16:41:48] <Demure_> Easily visible with the naked eye, say 20mm wide. But hard to guess right now as I don't have the parts with me, and this is not my photo, just something that shows the same issue.
[16:42:16] <Demure_> And that's an interesting option as well, though would that create the issue on one straight cut on the whole length, and not just at the start?
[16:42:18] <Deejay> gn8
[16:42:23] <Demure_> Night!
[16:43:41] <Demure_> Thanks for the suggestions, I think I'm good for now.
[16:43:57] <Demure_> gregcnc: Do you have any images of surface finish of sidewalls on singular axis cuts on your Emco mill?
[16:44:01] <bpuk> if it doesn't fix it - more photos :D
[16:44:16] <Demure_> Will be back in that case with proper scaled and measured photos, you can count on that ;)
[16:44:18] <gregcnc> If that's 20mm, it's not far off what I'm getting
[16:44:55] <Demure_> But you're getting that at 300mm/min
[16:45:00] <Demure_> I'd be happy with that
[16:45:21] <gregcnc> yes because 4k, 4 flutes
[16:45:29] <Demure_> Don't get me wrong, this finish I'm decently happy with, it's that anything faster becomes worse.
[16:45:35] <Demure_> Fair point
[16:45:46] <Demure_> Though at 2 flutes and same feeds or speeds I see no difference
[16:45:55] <gregcnc> 9.53Ø endmill
[16:45:55] <bpuk> another option if you can't solve it - try a 6 flute finisher ;)
[16:46:08] <Demure_> That is definitely one of the options, too. :)
[16:46:14] <Tom_L> baah nonsense
[16:46:17] <Demure_> And probably going to happen regardless due to my spindle speed limit
[16:46:28] <gregcnc> I have one of those to mess with
[16:46:45] <Tom_L> i wouldn't use 6flute anything on aluminum
[16:47:08] <gregcnc> you can, but only finishing pass, it's done all the time with slow spindles
[16:47:10] <Demure_> Not even if your max speed is 2000RPM?
[16:47:18] <Tom_L> not even
[16:47:27] <Tom_L> ever ever
[16:47:28] <gregcnc> boeing does it
[16:47:29] <Tom_L> never
[16:47:30] <Tom_L> !
[16:47:49] <bpuk> d'oh - forgot it was aluminum
[16:47:56] <Tom_L> i don't care what boeing, cessna, beech, bombardie, spirit or anyone else does
[16:48:39] <gregcnc> OK
[16:48:42] <Tom_L> it will load the cutter and there goes your work and cutter
[16:48:46] <gregcnc> they did real studies
[16:48:58] <Tom_L> you will get further with 2 (preferred) or 3 flute cutters
[16:49:15] <gregcnc> we are talking finishing pass
[16:49:29] <Tom_L> hardly worth the cost of a tool change
[16:50:06] <Demure_> As a hobbyist cost of tool changes is a lesser worry, but I'll chime in once I have experience on the matter;)
[16:50:48] <Tom_L> one more tool to change, post a cutter for etc etc
[16:51:32] <Tom_L> if your feeds and speeds are correct and the machine is rigid you will get a good finish
[16:52:03] <Tom_L> unless you're like some guys that wait until the cutter breaks to change it
[16:52:34] <Tom_L> BeachBumPete
[16:52:49] <Tom_L> i want to hear tremendous progress from you!!
[16:53:03] <BeachBumPete> define tremendous
[16:53:11] <Tom_L> mill up and cutting parts
[16:53:13] <Tom_L> :)
[16:53:24] <BeachBumPete> and since when is it such an importance to you?
[16:53:34] <Tom_L> just something to talk about
[16:53:43] <BeachBumPete> well it is getting there
[16:54:01] <BeachBumPete> the Z motor is installed and I have been making some modifications to the cable chain
[16:54:02] <gregcnc> what's left?
[16:54:20] <BeachBumPete> I am hoping that I do not need to cut a hole in the ceiling of the shop once they are completed
[16:54:29] <BeachBumPete> it is looking like it will work
[16:54:34] <Tom_L> good
[16:55:13] <BeachBumPete> once that is completed I just have to hook the solenoids back up for all the toolchanger stuff that I disconnected but none of that actually works yet :)
[16:55:17] <bpuk> Demure_/Tom_L - I'll be the first to recommend not going above 3 flute for alu - but routinely go higher myself. If you've got clip clearance (and a air blast) it can be worthwhile
[16:55:52] <CaptHindsight> Tom_L: the greatest best stuff happened today :)
[16:56:05] <Tom_L> i want to hear good news
[16:56:16] <BeachBumPete> once I get that stuff done I am ready to power up
[16:56:29] <Tom_L> BeachBumPete did you work out your electric pannel?
[16:56:38] <gregcnc> capthindsight new old lathe?
[16:56:47] <BeachBumPete> sort of have a plan for it..
[16:56:51] <CaptHindsight> 2 more days of summer/fall in the midwest
[16:57:16] <gregcnc> yes, i was just out there
[16:57:25] <BeachBumPete> was planning on working on it this past weekend but turned out it was my neice's wedding and we were in the bridal party
[16:57:30] <Tom_L> was unseasonablly warm here today
[16:57:39] <CaptHindsight> gregcnc: nah just posting happy happy thoughts
[16:57:42] <gregcnc> $1500 wasn't good enough, so $2000?
https://chicago.craigslist.org/sox/tls/5856022730.html
[16:57:42] <BeachBumPete> so I was needed for practice saturday and the actual wedding Sunday
[16:58:02] <Demure_> Just arried in Portugal, went from hitting 5c to hitting 19c in the late afternoon :))
[16:58:20] <Tom_L> 81 F for November..
[16:58:21] <CaptHindsight> gregcnc: never twice the same price
[16:59:09] <Tom_L> one more bit of great news
[16:59:18] <Tom_L> the election is finally over
[16:59:23] <CaptHindsight> https://chicago.craigslist.org/chc/tls/5879494465.html
[16:59:41] <gregcnc> news make it sound like it isn't
[16:59:55] <Tom_L> i don't watch much of that
[17:00:02] <Tom_L> it's just depressing
[17:00:16] <gregcnc> well intewebs or whatever
[17:00:57] <gregcnc> capt that is way out there
[17:02:07] <CaptHindsight> gregcnc: it's in skunks neck of the woods
[17:02:33] <gregcnc> yeah
[17:02:35] <Tom_L> he's already got tons of iron doesn't he?
[17:02:51] <CaptHindsight> they keep getting more
[17:03:00] <gregcnc> better add more make sure nobody walks off with the barn
[17:03:19] <roycroft> are you going to offer $1.97 for that lathe?

[17:06:47] <CaptHindsight> what's an automatic lathe?
[17:07:26] <Demure_> Programmable in some sort of way sans computer I believe?
[17:07:28] <CaptHindsight> is it like a screw machine?
[17:07:31] <Tom_L> i ran some of those years ago
[17:07:35] <Tom_L> probably
[17:07:43] <gregcnc> cams and stops
[17:07:44] <Tom_L> 6 & 8 spindle
[17:09:10] <Tom_L> that's probably a 2nd op machine

[17:19:31] <Demure_> Welp, I'm going to get some sleep now that I have some possible ideas to clear my head. Thankss & Gnight everyone.
[17:26:19] <zeeshan> i really have to say
[17:26:26] <zeeshan> there is little comparison between REAL cam
[17:26:28] <zeeshan> and conversational
[17:26:29] <zeeshan> http://imgur.com/AgIZ6Fs
[17:26:44] <zeeshan> conversational generates ancient tool paths
[17:26:45] <zeeshan> http://i.imgur.com/CWN2Kn5.jpg
[17:27:01] <zeeshan> i'm really not too impressed with mazatrol
[17:27:15] <zeeshan> its just like the dialog 11
[17:27:20] <zeeshan> or heidenhain tnc 151
[17:27:34] <zeeshan> what i am impressed by is the fact that a lot of mazaks are built in usa
[17:27:39] <zeeshan> http://i.imgur.com/c2rUt24.jpg
[17:27:46] <zeeshan> and look at the size of these linear guides
[17:29:29] <zeeshan> long live linuxcnc!!!
[17:30:04] <CaptHindsight> http://machinedesign.com/linear-motion/choosing-crossed-roller-bearing
[17:30:31] <zeeshan> ???
[17:32:13] <CaptHindsight> external magic roller bearings
[17:33:24] <CaptHindsight> does Mazak make their own bearings?
[17:36:58] <zeeshan> not sure
[17:37:17] <zeeshan> i was really suprised to find out that a lot of their machines are made in kentucky
[17:51:24] <jdh> me too
[17:56:14] <zeeshan> https://www.mazakcanada.com/machines/quick-turn-250msy/
[17:56:21] <zeeshan> i was looking and drooling over this machine
[17:56:25] <zeeshan> it'd easily fit in the garage
[18:03:33] <Tom_L> you gettin too much iron
[18:03:56] <Tom_L> no room for the chips to fly
[18:11:09] <zeeshan> anyone here using hsm?
[18:11:11] <zeeshan> (softwarE)
[18:11:13] <zeeshan> ?!?!
[18:15:38] <Duc> you mean HSMworks
[18:16:07] <zeeshan> that works too
[18:16:13] <zeeshan> its hsmworks in solidworks
[18:16:16] <zeeshan> and hsm in inventor
[18:16:21] <zeeshan> based off the same core.
[18:16:23] <Duc> I run it somewhat
[18:16:26] <Duc> whats the question
[18:16:32] <zeeshan> when youre drilling holes
[18:16:37] <zeeshan> and you select a .25" hole
[18:16:47] <zeeshan> is there anyway to automatically pick your 1/4" drill
[18:16:47] <zeeshan> ?
[18:16:55] <zeeshan> rather than having to go into tool manager?
[18:17:01] <zeeshan> or if you're tapping a m8x1.25 hole
[18:17:11] <zeeshan> is there anyway to know that you're going to drill first
[18:17:14] <zeeshan> then tap
[18:17:19] <zeeshan> mazatrol does this automatically..
[18:19:53] <Duc> not that I know of, I always select my own tools but im not a cnc machinist just a engineer that screws with machining on the side
[18:21:46] <Duc> do you have a full version of HSMworks or just the express
[18:21:53] <zeeshan> full
[18:22:08] <zeeshan> evaluating it for work
[18:22:25] <Duc> are you designing fixtures at same time as machining?
[18:22:37] <zeeshan> im just advising :P
[18:22:52] <zeeshan> i might get involved in fixture design, but that is not my job purpose
[18:22:58] <zeeshan> i'll help out whenever i can
[18:23:36] <zeeshan> my job is retrofit designs/customer service/sales for gypsum industry
[18:23:38] <Duc> its really nice for updating the model and regenerating the tool path at the same time
[18:23:44] <zeeshan> yes
[18:23:46] <zeeshan> that is a major +
[18:23:51] <zeeshan> especially as our designs change
[18:23:57] <zeeshan> the tool paths carry over
[18:24:14] <Duc> in same file so you always know its up to date
[18:24:18] <MacGalempsy> sweet, about yo pid tune the new print bed and nozzle
[18:24:27] <zeeshan> yes
[18:24:44] <zeeshan> and whenever the design changes
[18:24:47] <Duc> now mastercam does have a solidworks plugin
[18:24:50] <zeeshan> and you're using revision control in for example vault
[18:25:01] <zeeshan> now you have revisions of those tool paths along with designs!
[18:25:02] <zeeshan> win win
[18:25:22] <zeeshan> i have been going to training for conversational programming
[18:25:27] <zeeshan> it's a horrible thing.
[18:25:27] <Duc> true I do like doing toolpaths in assemblies to check for errors
[18:25:37] <zeeshan> great for simple stuff like if you gotta slot or drill a couple holes
[18:25:55] <zeeshan> but asap you are dealing with contours
[18:25:56] <zeeshan> it's hrorible
[18:26:08] <zeeshan> it's a frigging click of a line in cam.
[18:26:09] <Duc> finger cam works better for the simple stuff
[18:26:18] <Tom_L> we only used conversational on the lathe
[18:26:30] <Tom_L> sucks for anything else
[18:26:31] <zeeshan> Tom_L: cause you were likely making simple parts!
[18:26:38] <Tom_L> yeah
[18:26:41] <zeeshan> http://i.imgur.com/9VdI0rs.jpg
[18:26:44] <zeeshan> sorry for the angled picture
[18:26:53] <zeeshan> i had to program that part..
[18:27:02] <zeeshan> first of all your engineering drawings will never have those edge points
[18:27:14] <Tom_L> looks simple enough
[18:27:15] <zeeshan> cause most engineers won't realize you need those dimensions
[18:27:24] <zeeshan> yea so its basically a step on the edge of a part
[18:27:31] <zeeshan> a massive counterbore
[18:27:34] <zeeshan> and some holes
[18:27:44] <zeeshan> you have to draw each one of those edges..
[18:27:55] <zeeshan> in cam you'd just click all 4 edges
[18:27:59] <zeeshan> it'd do the math
[18:28:01] <zeeshan> and you're good to go.
[18:28:12] <zeeshan> the hole is another click, good to go
[18:28:13] <Duc> HSM you can set your model stock at the start
[18:28:20] <zeeshan> yea
[18:28:34] <zeeshan> hsm doesnt do a great job of stock definition tho
[18:28:37] <zeeshan> cause when you want to flip the part
[18:28:39] <zeeshan> it forgets.
[18:28:39] <Tom_L> how does HSM merge the part with the stock?
[18:28:45] <Tom_L> in catia you make an assembly
[18:28:57] <Duc> my coworkers would rather use mastercam for fine tunning but I like HSMworks for simple kitting trays I do
[18:29:00] <zeeshan> Tom_L: you can make an assembly
[18:29:06] <zeeshan> or just use a multi-solids part file
[18:29:16] <zeeshan> mastercam is pretty good
[18:29:21] <zeeshan> but hsm is better for your everyday cam
[18:29:30] <zeeshan> i use mastercam a lot
[18:29:32] <zeeshan> more than hsm..
[18:29:40] <Duc> yea i might have both at home and I choose the free HSM for simple stuff
[18:29:49] <zeeshan> Duc: for example
[18:29:56] <zeeshan> if you have multiple holes are multiple heights
[18:30:06] <zeeshan> and assume they're the same diameter
[18:30:17] <zeeshan> you just click one of them, choose one option
[18:30:22] <zeeshan> and it'll generate you the entire tool path
[18:30:43] <Duc> I believe HSM will if you choose the inside cylinder instead of the circle up top
[18:30:54] <zeeshan> yes
[18:31:03] <zeeshan> i absolutely love the fact that when you're in the drill tool path creation
[18:31:06] <zeeshan> and you highlight a cylinder
[18:31:09] <zeeshan> it tells you the size
[18:31:10] <zeeshan> =D
[18:31:16] <zeeshan> mastercam for solidworks does not do that!
[18:31:27] <zeeshan> you gotta frigging exit the tool path and measure
[18:31:32] <Duc> errr
[18:31:33] <zeeshan> or find it in the design tree
[18:32:09] <Duc> still not sure how do use a ball nose endmill to make a channel in hsm except to follow a sketch line
[18:33:19] <zeeshan> like
[18:33:21] <zeeshan> it's a straight cut?
[18:33:40] <Duc> yep
[18:33:56] * zeeshan fires it up
[18:34:18] <Duc> so plunge a 5/4 end mill about .75 deep in a material and move right about 3 inches
[18:34:40] <Duc> I modeled the channel but I cant get the tool to follow it
[18:35:27] <zeeshan> 5/4?
[18:35:31] <zeeshan> 1/4? "
[18:36:30] <Duc> 1.25"
[18:36:44] <zeeshan> that is a huge end mill
[18:36:44] <zeeshan> :P
[18:36:47] <zeeshan> er ball mill
[18:37:37] <Duc> We place small parts into the channel on the assembly line for the next station to use. easy to scoop the parts out with a finger
[18:38:45] <Duc> it is a big mill but its plastic
[18:38:53] <Duc> that we are cutting into
[18:39:41] <Tom_L> zeeshan what did you program that part in?
[18:39:56] <zeeshan> mazatrol
[18:40:08] <Tom_L> oh conversatonal?
[18:40:10] <Tom_L> ick
[18:40:20] <zeeshan> yea
[18:40:31] <zeeshan> i hope you agree it'd be a pain in the ass
[18:40:35] <zeeshan> especially if you were looking at a real print
[18:40:45] <zeeshan> (without those additional dimensions)
[18:41:14] <Tom_L> what's the dotted line for?
[18:41:20] <zeeshan> original stock
[18:41:22] <zeeshan> to remove
[18:42:33] <Tom_L> what's the cube size on it?
[18:42:40] <Duc> guess most engineer wouldnt know the material size being used
[18:45:34] <zeeshan> Duc: you're right
[18:45:41] <zeeshan> slot op doesnt work
[18:45:52] <zeeshan> you gotta use a regular contour
[18:46:02] <Duc> frustrating
[18:46:24] <Duc> do it try to 3d mill it at that point
[18:48:45] <zeeshan> for the ball nose?
[18:48:53] <zeeshan> no just use 2d contour
[18:49:15] <Duc> is a straight plunge in then over? or a more complex tool path
[18:49:21] <zeeshan> plunge and over
[18:49:31] <zeeshan> lemme take a ss
[18:51:41] <zeeshan> pos imgur
[18:51:43] <zeeshan> wont let me upload
[18:52:27] <Duc> lol
[18:52:51] <Duc> my dam work files are in solidworks 2016 so I can post a pic of mine
[18:53:58] <zeeshan> https://postimg.org/image/r8w0v6a93/
[18:54:02] <zeeshan> ignore the half moon
[18:54:08] <zeeshan> too lazy to model
[18:54:14] <zeeshan> https://postimg.org/image/97cvxdg87/
[18:54:14] <IntegratorBrazil> To custom build a machine with linuxcnc what skills i need regarding software languages ? C++, python and G code ?
[18:54:37] <zeeshan> python would be good if you're trying to make custom modules
[18:55:06] <Tom_L> you need gcode knowledge to run it
[18:55:31] <Tom_L> you may need to know about bitfiles if you use mesa hardware which is recomended
[18:55:45] <Tom_L> plenty here that can help
[18:55:47] <IntegratorBrazil> Python ok. Any book to recomend ? I am almost starting a reading of "Real world instrumentation with python" writen by Hughes.
[18:56:34] <zeeshan> http://turbozee84.imgur.com/all/#1
[18:56:36] <zeeshan> er
[18:56:39] <zeeshan> http://i.imgur.com/LuxlXA0.jpg
[18:56:43] <zeeshan> heres another part for conversational
[18:56:48] <zeeshan> =D
[18:56:51] <Duc> dam i might have to try that at work tomorrow
[18:56:52] <zeeshan> you can do that pretty quick in conversational
[18:57:03] <zeeshan> Duc: make sure you turn off tool compesation
[18:57:07] <zeeshan> in the contour tool path
[18:57:14] <zeeshan> otherwise it'll think it's a wall..
[18:57:20] <Duc> zeeshan: does it work if thats off
[18:57:27] <zeeshan> ya
[18:57:40] <Duc> wonder what I was doing wrong
[18:57:41] <zeeshan> otherwise it wont follow your sketch line
[18:57:50] <Tom_L> zeeshan do they make a spiral notebook for all their parts?
[18:58:00] <zeeshan> Tom_L: whatcha mean
[18:58:16] <Duc> so your setting it to follow the sketch
[18:58:16] <Tom_L> those prints are all nice n spiral bound
[18:58:23] <zeeshan> yes
[18:58:33] <zeeshan> Duc: yes make sure you select turn off tool compensation
[18:58:36] <zeeshan> normally its set to computer
[18:58:47] <IntegratorBrazil> What is gonna be a main issue to build something like this ?
https://www.youtube.com/watch?v=0GjVNHWjyCY
[18:58:50] <Tom_L> sorted by assembly ?
[18:59:04] <zeeshan> when you draw a line, and you choose contour... and you're using a 1/2" tool for example and you got computer selected
[18:59:19] <zeeshan> it'll offset the tool away by 1/4"
[18:59:28] <zeeshan> but if you turn off compensation, it'll follow exactly the line
[18:59:30] <zeeshan> does that make sense?!
[18:59:39] <Duc> so no just clicking on the channel bottom to make it work?
[18:59:40] <Tom_L> IntegratorBrazil, an understanding of what you need
[18:59:45] <zeeshan> Duc: nope
[18:59:49] <zeeshan> that is only for flat bottom slots
[19:00:00] <zeeshan> mastercam is the same way
[19:00:21] <Duc> ah ok we are doing it the same way then
[19:00:34] <zeeshan> Tom_L: this is just random parts they give you to program
[19:00:40] <zeeshan> it's not parts of their machine
[19:00:49] <zeeshan> it actually might be :P
[19:00:51] <zeeshan> but i dont know haha
[19:01:12] <Tom_L> we always got prints on huge rolls
[19:01:30] <Tom_L> had to tear em up into workable sections :)
[19:01:32] <IntegratorBrazil> I need a machine that make 3d bends on steel pipes. 300K USD for that machine is out of my budget.
[19:02:18] <Duc> 300k is cheap for that machine
[19:02:26] * zeeshan was thinking same
[19:02:26] <zeeshan> hehe
[19:02:58] <Tom_L> IntegratorBrazil, this one is only $109 US
http://www.northerntool.com/shop/tools/product_200659552_200659552?cm_mmc=Google-pla&utm_source=Google_PLA&utm_medium=Metal%20Fabrication%20%3E%20Pipe%20%2B%20Bar%20Fabrication&utm_campaign=Klutch&utm_content=49682&gclid=CIWzu8TFrtACFQimaQodJQ4K3g
[19:03:02] <IntegratorBrazil> Well, its cheap, but as i said, out of my budget.
[19:03:06] <Duc> unless you have made mechanical skills and electrical programming then forget it
[19:03:45] <zeeshan> get an oxy torch
[19:03:47] <zeeshan> and bend it by hand :D
[19:03:50] <malcom2073_> How do they grab on to the pipe to push it, just clamps and hydraulics?
[19:04:04] <Tom_L> by the time you design it and figure out all the hydraulics etc you will likely have that invested
[19:04:17] <Tom_L> malcom2073_ i think so yes
[19:04:20] <zeeshan> IntegratorBrazil: try to find an old machine
[19:04:22] <zeeshan> and retrofit it!
[19:04:22] <zeeshan> :D
[19:04:45] <Tom_L> zeeshan i haven't seen those around that much, you may not find an old one
[19:05:00] <malcom2073_> They seem to be a fairly new thing
[19:05:04] <Tom_L> yup
[19:05:05] <IntegratorBrazil> I am planning to build a small scale to bend just wires. Then i will move to the real size.
[19:05:07] <zeeshan> wat
[19:05:10] <zeeshan> they've been around forever!!!!!!
[19:05:13] <zeeshan> for wire bending
[19:05:23] <malcom2073_> Oh for wire, I meant tube
[19:05:24] <Tom_L> yeah but not on that scale
[19:05:36] <malcom2073_> There's a cnc wire bending place up the street from me, like a mile
[19:05:51] <zeeshan> https://www.youtube.com/watch?v=YA2InDmSHyw
[19:05:54] <zeeshan> we're talking about this right?
[19:06:09] <zeeshan> they've been using this in automotive
[19:06:09] <malcom2073_> No, look at the video IntegratorBrazil posted
[19:06:12] <zeeshan> to do ac lines and shit
[19:06:14] <zeeshan> forever
[19:06:25] <Duc> nope
[19:06:27] <Tom_L> zeeshan the other one is way cooler
[19:06:31] <IntegratorBrazil> No Mandrel cnc cannot make variable radius bend.
[19:06:42] <zeeshan> O
[19:06:52] <zeeshan> that machine only costs 300k?!?!
[19:07:16] <Tom_L> line up more work for it and buy one
[19:07:19] <IntegratorBrazil> Yes sir. 300k bucks.
[19:07:32] <zeeshan> it doesnt look too complex
[19:07:34] <zeeshan> at least the idea of it
[19:07:38] <Tom_L> no
[19:07:43] <zeeshan> the front die just moves in 2 axis
[19:07:45] <Duc> tuning tables are worth there weight in gold
[19:07:47] <zeeshan> and then you need a feeder..
[19:07:55] <zeeshan> and youre good to go
[19:07:59] <IntegratorBrazil> Yes, this model is just a 2 axis.
[19:08:05] <Tom_L> so when can you deliver this zeeshan?
[19:08:12] <zeeshan> gimme 150k
[19:08:15] <zeeshan> i deliver in 1 month
[19:08:21] <jdh> I want to bend some 6061-t6 without it snapping, any suggestions?
[19:08:26] <zeeshan> jdh: heat
[19:08:32] <jdh> how much
[19:08:36] <zeeshan> propane
[19:08:47] <jdh> bend while hot, or just remove temper first?
[19:08:52] <Tom_L> you'll likely need to re'temper it after
[19:08:56] <zeeshan> bend while hot
[19:09:07] <Tom_L> use gloves
[19:09:09] <jdh> heh
[19:09:15] <zeeshan> what are you bending
[19:09:17] <IntegratorBrazil> Induction heating and bending the T6
[19:09:18] <zeeshan> like 1/8 flat bar?
[19:09:21] <jdh> yeah
[19:09:27] <zeeshan> yea just go like that
[19:09:48] <jdh> I did some test bends on some scrap and they all went fine.
[19:09:57] <jdh> tried bending my machined part and it snapped
[19:10:04] <jdh> (different scrap)
[19:10:06] <Tom_L> work hardened?
[19:10:15] <jdh> not likley
[19:10:51] <jdh> torch will make it ugly
[19:10:55] <zeeshan> no
[19:11:03] <zeeshan> thats how ive done my auto brackets
[19:11:13] <Tom_L> those fugly ones?
[19:11:17] <zeeshan> ;[
[19:11:19] <Tom_L> heh
[19:11:45] <IntegratorBrazil> What about ROS (robotic operating system) ? LinuxCnc do the same that ROS ?
[19:20:15] <malcom2073_> ROS and linuxcnc are different things, so no.
[19:21:58] <IntegratorBR> 10 4
[19:22:45] <malcom2073_> That being said, I believe there are some ROS packages for motor control, but afaik nothing nearly as coordinated or realtime as linuxcnc... but then again it's not intended to be
[19:23:15] <malcom2073_> Oh and, ROS is the devil
[19:24:08] <IntegratorBR> "" devil" why macom ?
[19:25:04] <malcom2073_> If you're interested in having a conversation about that, use it for a couple of months then come back and we'll talk technical details.
[19:26:27] <IntegratorBR> 10 4
[19:27:33] <Tom_L> linuxcnc has been adapted for a variety of different types of machines
[19:28:25] <Tom_L> skunkworks didn't you compile a bunch of videos of machines?
[19:34:34] <Tom_L> i guess some of them are in the 'showcase'
[19:37:05] <IntegratorBR> These delta softpic hexapods are really biting some workers out of jobs.
[19:37:08] <IntegratorBR> https://www.youtube.com/watch?v=nGcprqGT9V0
[19:38:32] <Tom_L> robots aren't union members
[19:39:10] <zeeshan> =D
[19:39:19] <zeeshan> ideally a manufacturing place should be all robots
[19:41:21] <Tom_L> the workers just need to be smarter
[19:42:11] <jdh> torch helped for the bend. if only I had bent on the correct side of my index pocket
[19:42:34] <Tom_L> load said product from the automated line into a google car for driverless delivery right to your doorstep
[19:43:58] <zeeshan> jdh: lol
[19:44:01] <zeeshan> what are you makin
[19:44:02] <jdh> I got a couple of ABB robots on my newest machine (work). Two more coming on one I have being built now.
[19:44:04] <IntegratorBR> Almost midnight, time to take a rest, have a good one gentlemen.
[19:44:09] <Tom_L> scrap it seems
[19:44:16] <jdh> zeeshan: u-shaped bracket for a dive light.
[19:44:29] <zeeshan> nice
[19:44:35] <Tom_L> IntegratorBR come back with more questions
[19:44:45] <zeeshan> i like how jdh starts his dive projects in the winter
[19:44:49] <zeeshan> and then dissapears during the summer
[19:44:52] <IntegratorBR> Sure i will. Thanks a lot for you answeres.
[19:44:52] <zeeshan> that's kind of what i did this year :)
[19:44:56] <jdh> https://www.scubastore.com/f/6/65130_2/best-divers-goodman-handle.jpg
[19:44:59] <jdh> similar to taht
[19:45:01] <Tom_L> hey, he'll be ready when season hits
[19:45:06] <jdh> what season?
[19:45:11] <Tom_L> dive season
[19:45:16] <jdh> it's always dive season
[19:45:20] <zeeshan> :P
[19:45:29] <jdh> I'll be diving friday-tuesday
[19:45:33] <zeeshan> im doing a solo trip into the bush next year
[19:45:39] <zeeshan> i've been prepping
[19:45:55] <Tom_L> don't get eaten by a bear
[19:45:56] <zeeshan> about 200 miles from civilization ;D
[19:46:01] <jdh> what bush?
[19:46:04] <zeeshan> 100 miles of off road
[19:46:10] <jdh> in .ca?
[19:46:14] <zeeshan> yes
[19:46:22] <zeeshan> theres a creek i'd like to explore
[19:46:33] <jdh> uhm... almost all of .ca is 200 miles from civilization
[19:46:38] <zeeshan> haha
[19:46:53] * jdh points at map
[19:47:29] <skunkworks> Tom_L, what?
[19:47:58] <Tom_L> i think i found what i was looking for
[19:48:07] <Tom_L> the videos or pics of retrofits
[19:48:18] <jdh> I put a 0.015" deep slot in the part for a reference. It bent on the slot and stretched it about 3x as wide as it was
[19:49:37] <roycroft> that's because almost all canadians live within 100 miles of the us border
[19:49:54] <jdh> it's because canada is fucking huge
[19:50:26] <roycroft> 75% is the actual percentage
[19:50:34] <zeeshan> you'll be suprised
[19:50:37] <roycroft> yes, it's a huge, beautiful country
[19:50:38] <zeeshan> how far people have gone up north
[19:50:46] <roycroft> but almost everyone lives as close to the 49th as possible
[19:50:55] <roycroft> all the major cities are close to the us border
[19:50:59] <zeeshan> that's true
[19:51:12] <zeeshan> but that doesnt mean al lthe land up north is untouched
[19:51:15] <zeeshan> there are some areas that are
[19:51:17] <roycroft> vancouver, calgary, winnepeg, toronto, montreal, quebec, etc.
[19:51:17] <jdh> give them a few years, they might want a bigger buffer
[19:51:18] <zeeshan> but they are really far
[19:51:36] <Tom_L> jdh we'll just build a wall
[19:51:36] <roycroft> now the argument can be made the the us is not a civilised country
[19:51:47] <roycroft> so living close to the us does not necessarily mean living close to civilisation
[19:51:48] <jdh> they will build a wall
[19:51:57] <Tom_L> and want us to pay for it?
[19:52:04] <jdh> no, to keep us out
[19:53:21] <roycroft> it would be one hell of a wall
[19:53:27] <roycroft> 8891km long
[19:54:13] <Tom_L> how long is the great wall?
[19:55:26] <roycroft> that's a difficult question to answer, because it's actually a series of walls
[19:55:44] <Tom_L> 5,500 miles long, but a new archaeological survey done by China's State Administration of Cultural Heritage says the Great Wall is more than double than that length.
[19:55:52] <roycroft> but approximately 21,000km by most estimates
[19:56:00] <roycroft> yes
[19:56:26] <roycroft> the ming wall is 8851km (5500 miles) long
[19:56:30] <roycroft> but it's just one of the walls
[19:58:07] <roycroft> likewise, the canadian wall would have to be several walls
[19:58:09] <roycroft> at least three
[19:58:22] <roycroft> one across the main canadian-us border
[19:58:28] <roycroft> one across the yukon-alaska border
[19:58:46] <roycroft> and one enclosing that little segment of minnesota that is in manitoba
[19:59:02] <roycroft> oh, also a short wall separating point roberts washington from british columbia
[19:59:04] <malcom2073_> Eh
[19:59:07] <malcom2073_> you can keep the UP
[19:59:22] <roycroft> i'm not talking about the up
[19:59:27] <roycroft> that's part of michigan, not minnesota
[19:59:39] <roycroft> no, there's a little pocket of minnesota that is isolated in manitoba
[20:00:02] <roycroft> https://en.wikipedia.org/wiki/Northwest_Angle
[20:01:33] <malcom2073_> Ah oh I misread
[20:01:58] <malcom2073_> That's odd heh
[20:05:19] <roycroft> the cbc claim that 90% of canadians live within 100 miles of the us border
[20:07:34] <malcom2073_> I don't doubt it. There's an unimaginable amount of wilderness up north
[20:07:51] <roycroft> most people don't realise that canada is larger than the us
[20:07:54] <roycroft> including alaska
[20:07:57] <malcom2073_> Significantly
[20:08:03] <malcom2073_> But only has the population of say, california
[20:08:29] <roycroft> less than california, i'm pretty sure
[20:08:40] <malcom2073_> Somewhere in that realm, 20-30 million?
[20:08:45] <malcom2073_> I'm too lazy to wiki it :)
[20:08:51] <roycroft> 36 million canadians now
[20:08:59] <malcom2073_> Like rabbits!
[20:09:11] <roycroft> 40 million californians
[20:09:16] <roycroft> so roughly equivalent
[20:09:24] <roycroft> i thought california had more people
[20:09:27] <roycroft> it sure seems like they do
[20:10:44] <roycroft> we have 1/10 of california's population here in oregon
[20:11:25] <roycroft> but we're 55% as large as california
[20:11:37] <roycroft> unfortunately our state is filling up with californians
[20:11:51] <roycroft> so the population density will probably become more equal over time
[20:11:58] <Tom_L> send em back
[20:12:07] <roycroft> BUILD THE WALL!
[20:12:13] <roycroft> we had a governor
[20:12:18] <roycroft> his name was tom, btw :)
[20:12:20] <roycroft> tom mccall
[20:12:27] <Tom_L> gotta have a oregon greencard to enter...
[20:12:34] <roycroft> he put up signs on our border saying "thank you for visiting oregon, but please don't move here"
[20:12:56] <roycroft> this was back in the '70s
[20:17:26] <Duc> andypugh: you on?
