[00:40:13] <XXCoder> trentster: forgot what machine you was working on?
[00:42:57] <trentster> XXCoder: its a Home made DIY router
[00:43:05] <XXCoder> cool :)
[00:43:11] <XXCoder> router here but less homebrew
[00:43:29] <trentster> 6040?
[00:43:46] <XXCoder> 3040 actually
[00:43:47] <trentster> I am glad you finally have your machine up and running
[00:43:56] <XXCoder> yeah too bad I cant cut anything
[00:44:04] <XXCoder> garage is still being cleaned and stuff
[00:45:07] <trentster> wow! - you have a lot of passion for cnc- props to you, you are definitely one of the most active people in the channel and you dont have an up and running machine yet
[00:45:23] <XXCoder> its working but just cant cut anything
[00:45:34] <XXCoder> because machines in downstairs living room
[00:46:38] <trentster> yup, I had my machine on dining room table for awhile while I was testing it etc. That was up until my wife freaked when I started testing cutting aluminium - LOL
[00:46:47] <trentster> It was straight to the garage after that ;-)
[00:47:01] <XXCoder> yeah no room in garage still
[00:47:56] <trentster> If I was you, and had a dayjob as a machinist, I definately would have made a machine at work and spent the money on stuff like hiwin rails etc
[00:48:37] <XXCoder> I suppose yeah but then I was already getting parts of machine well before I even got that training job lol
[00:49:47] <trentster> aah, its ironic the timing then.
[00:50:13] <XXCoder> yah
[00:50:18] <trentster> I am sure we can look forward to some interesting creations from you - once you are at the cutting stage
[00:52:53] <XXCoder> yeah
[00:52:58] <XXCoder> its mostoly artwork
[00:54:55] <trentster> I can't wait until I can mount the new spindle on the machine and replace the current 400W one.
[00:55:18] <trentster> I have been amazed at what I have done with a 400w spindle the new one will be awesome.
[00:55:35] <trentster> Just need to buy a 80mm spindle mount - then I am done
[00:55:41] <XXCoder> nice, mine is 500w but its noit a proper spindle and are acually grinder.
[00:55:49] <XXCoder> 27000 rpm lol
[00:55:51] <XXCoder> fast.
[00:56:03] <trentster> wow thats insanely fast
[00:56:19] <trentster> my 400w only did 12000
[00:56:49] <XXCoder> well negative is min speed is also 27000
[00:57:07] <trentster> what are you going to use it for?
[00:57:28] <XXCoder> wood artwork :)
[00:57:40] <XXCoder> I plan to evenually try mill alum
[00:58:23] <trentster> hmmmm,
[00:58:58] <trentster> woulent you preferably want lower rpm for aluminum
[00:59:11] <trentster> my 400w handles 3d carving just fine
[00:59:37] <XXCoder> normally yeah
[00:59:54] <XXCoder> maybe I will evenually be able to alter my other wood router
[01:00:00] <XXCoder> so it has no fob blocking clamp
[01:00:17] <XXCoder> that one has range from 3000 to 12000 rpm
[01:00:48] <trentster> This is when I had retarded max acceleration settings before I figured out how they work
[01:00:49] <trentster> https://www.youtube.com/watch?v=jlj5SKnmd9I
[01:01:00] <XXCoder> I orginially bought that but as it turns out while it has sleeve perfect size (43mm) but has a stupid screw fob
[01:01:17] <trentster> I had ipm set to 25ipm and max acceleration set to 10 lol
[01:01:19] <XXCoder> horsie!
[01:01:36] <trentster> https://pbs.twimg.com/media/CQ8ZUYlUcAA0d1k.jpg
[01:01:40] <XXCoder> turaround is quite quickk
[01:01:51] <XXCoder> thankfully wood is weak lol
[01:02:37] <XXCoder> 25 ipm and 10 accel interesting
[01:02:58] <XXCoder> mines set to 50 mm/s max speed and 200 mm/s^2 max accel
[01:02:59] <trentster> he yeah - I did not RTFM
[01:05:02] <trentster> I now have 2.5ips and accelaration around 40
[01:05:04] <XXCoder> heh happens
[01:05:22] <XXCoder> 40 in/s^2 should be fine yeah
[01:06:15] <trentster> I still managed to cut this https://twitter.com/trentster/status/651695918459170816
[01:06:23] <trentster> and this with the borked settings tho
[01:06:30] <XXCoder> wow
[01:06:34] <XXCoder> looks amazing
[01:06:44] <XXCoder> how did you generate gcode? or was it picture to gcode?
[01:06:52] <trentster> https://twitter.com/trentster/status/651695918459170816
[01:07:18] <trentster> and the gantry plates were done with an arduino before linuxcnc was up and running
[01:08:11] <trentster> https://twitter.com/trentster/status/632520188873695232
[01:08:28] <XXCoder> yours look bit similiar as mine
[01:08:37] <XXCoder> some differences
[01:08:47] <trentster> I used vectric to generate the vcarve stuff
[01:09:16] <XXCoder> thats cool
[01:10:39] <trentster> yeah vectric is amazing - its a zillion times easier to use than Fusion360 - which I still need to master
[01:11:15] <XXCoder> it seem to be suitable for artwork
[01:13:45] <trentster> what vectric?
[01:13:51] <XXCoder> yeah
[01:14:02] <trentster> Yeah Aspire is great for artwork for sure
[01:14:07] <XXCoder> in least nice for details for woodwork anyway
[01:14:12] <trentster> If I was milling metals would use Fusion
[01:14:34] <trentster> Yeah its also very easy to do wood inlays
[01:14:56] <trentster> its just not cheap to buy
[01:15:08] <XXCoder> yeah
[01:15:53] <trentster> unless you happen to have $2k lying around
[01:16:22] <XXCoder> lol
[01:16:50] <XXCoder> "$2000? hm think I can get that and car from around couch stuffing"
[01:20:58] <trentster> heh
[01:21:38] <trentster> The dangerous thing about a CNC hobby is that I can tell from myself it quickly becomes an obsession. obsession = $$
[01:22:19] <XXCoder> heh yeah in least it makes stuff
[01:22:21] <trentster> I now want to get some hiwin rails and I also want to get a Mill and a lathe, but my wallet does not agree with me ;-)
[01:22:30] <XXCoder> unlike very expensive metal detecting hobby.
[01:22:41] <XXCoder> good luck even getting 0.1% of money back on metal detecting
[01:23:26] <gphillips> do you guys use your cnc
[01:23:34] <gphillips> to engrave with images from the net
[01:23:47] <XXCoder> I plan to MAKE images to engrave stuff
[01:24:00] <XXCoder> and maybe some downloaded ones, personal use only
[01:24:26] <trentster> gphillips: yeah I do both. The software is really what counts that generates the cam stuff
[01:25:14] <trentster> There is also quite a big business for people who create 3d model files and sell them on the net for people to use
[01:25:18] <gphillips> i know i use estlcam, because I use Ramps 1.4 board with marlin, but I was wondering if there an easier way to change the size of the images
[01:25:47] <trentster> https://www.vectorart3d.com/
[01:26:04] <XXCoder> so many cams
[01:26:23] <XXCoder> and so few even half decent cam open source
[01:27:24] <gphillips> well I have tried lots different software and so far estlcam has definately been the easiest for me to use
[01:28:15] <gphillips> and I use http://vectormagic.com/home to convert regular images to vectors
[01:29:13] <trentster> gphillips: Have you looked at the vectric training videos they are really very comprehensive
[01:29:14] <XXCoder> why not use inkscape to create vector images?
[01:29:26] <trentster> http://support.vectric.com/tutorials/V8/AspireProjectIndex.html
[01:29:50] <XXCoder> trentster: :(
[01:29:53] <XXCoder> its in video...
[01:29:56] <XXCoder> and not captioned
[01:30:25] <trentster> XXCoder: yeah I know - sorry dude :-(
[01:30:29] <XXCoder> np
[01:30:33] <XXCoder> not your site
[01:31:37] <XXCoder> I prefer tutorials to be in website format so i can read up and down as reference
[01:31:47] <XXCoder> videos I would have to go back and seek info
[01:31:55] <XXCoder> so even captioned it still has issues
[01:33:43] <XXCoder> freecad has pretty nice tutorials, too bad its bit out of date
[01:33:47] <XXCoder> some dont work
[01:34:03] <XXCoder> freecad also has cam stuff but no tutorials on that at all
[01:36:00] <trentster> XXCoder: you should email them and ask them to make captions available for the deaf.
[01:36:17] <XXCoder> yeah when I'm actual customer I will
[01:41:26] <archivist> ask before! so they have reason
[01:41:35] <XXCoder> hmm guess so
[01:48:54] <XXCoder> https://www.kickstarter.com/projects/mst3k/bringbackmst3k?ref=hero
[02:00:17] <XXCoder> jeez. http://i.crackedcdn.com/phpimages/article/9/5/6/476956_v1.jpg
[02:08:46] <jesseg> Is there a G code to do an arc with a different starting and ending radii?
[02:09:54] <XXCoder> no, but any curve can be fitted
[02:10:22] <XXCoder> hmm maybe not in this case
[02:10:29] <XXCoder> just curious why
[02:12:56] <Deejay> moin
[02:14:53] <jesseg> XXCoder, because it'd be so slick if I could pocket a 1 inch round pocket by first doing a 360 degree arc, then by doing a spiral all the way to the center because the machine would never have to slow down for corners :P
[02:15:34] <XXCoder> just do ever-smaller 1/4 circles
[02:16:23] <XXCoder> (it would need small g1 lines to get to one of axles so it dont draft)
[02:16:47] <jesseg> since I'm writing my own tp and 2D cad program I think I'll just make a custom G code for spiral LOL
[02:17:05] <jesseg> just wanted to make sure there wasn't an existing Gcode for it :D
[02:17:18] <XXCoder> whats wrong with just smaller circles?
[02:17:56] <jesseg> dood why do we even need G2 and G3? What's wrong with a bunch of line segments anyway?
[02:18:23] <XXCoder> lots of stops
[02:18:26] <jesseg> There's something elegant about being able to fly into an arc without having to do it in a hundred little steps.
[02:18:33] <XXCoder> its better to interplote a curve
[02:19:11] <jesseg> A good machine doesn't have to do lots of stops if it can plan the trajectory velocities correctly
[02:19:28] <jesseg> not if your arc is made up of line segments smaller than the machine's resolution :P
[02:20:01] <jesseg> but yeah that's why I want a spiral arc G code interpolated *on* the machine -- because it's better :D
[02:20:45] <jesseg> The arc supports slewing the Z for a helical cut, and even supports multiple turns as I recall
[02:20:47] <XXCoder> some gcode machines do have that if I recall
[02:20:55] <XXCoder> some CAM do generate gcode on that
[02:21:02] <XXCoder> but dunno linuxcnc support
[02:21:11] <jesseg> A spiral, or a helix?
[02:21:16] <XXCoder> hmm
[02:21:23] <XXCoder> helix actually so nm
[02:21:54] <jesseg> yeah the spiral is the perfect counterpart to the helix. :D
[02:22:33] <XXCoder> check if linuxcnc supports g02.1 and g03.1
[02:22:37] <XXCoder> spiral
[02:22:51] <jesseg> I thought .? was variables
[02:22:57] <jesseg> but I don't know much
[02:23:13] <XXCoder> some machines has custom gcode added
[02:23:29] <XXCoder> one mchine I use has g54.1 h0 to 99
[02:23:38] <XXCoder> it extends number of coordites
[02:23:43] <jesseg> ahhh I see
[02:23:56] <XXCoder> http://okumacnc.blogspot.com/2011/06/how-to-make-spiral-interpolation-g021.html
[02:24:06] <XXCoder> no idea if linuxcnc has support of that
[02:24:20] <jesseg> ahh cool thanks so much!
[02:24:52] <jesseg> looks like I have some reading to do and quite possible an existing Gcode for spirals.
[02:26:21] <XXCoder> from what I see answer might be no
[02:26:28] <XXCoder> maybe time to extend linuxcnc lol
[02:26:52] <jesseg> No? Oh, linuxcnc doesn't yet support it?
[02:27:02] <XXCoder> dont appear to be the case
[02:27:07] <trentster> yeah, I have run into problems with slowdown on curves as well, its a pain especially when cutting stuff like acrylic
[02:27:51] <XXCoder> http://wiki.linuxcnc.org/cgi-bin/wiki.pl?G12-13#G13_Equal_EMC2_Subroutine_to_Haas_like_Circular_Spiral_Pocket_Milling
[02:27:53] <XXCoder> HMM
[02:27:54] <XXCoder> dunno
[02:28:00] <trentster> There must be a better way to do it, I doubt guys like the Tormach users would put up with that.
[02:28:08] <XXCoder> python script there too
[02:28:09] <jesseg> not surprising. With most people cad programs to generate nc files by brute force, and very little hand-coding of gcode files, neat things like spirals and helixes aren't in much demand
[02:28:54] <jesseg> hmmm
[02:29:05] <archivist> linuxcnc has a new trajectory planner to make the short segment slowdown problem much better
[02:29:35] <jesseg> You can do [math] in gcode files? haha i learn something every day
[02:30:05] <XXCoder> linuxcnc do allow you to have math exp in gcode
[02:30:13] <archivist> yes I do do maths in my gcode
[02:30:20] <jesseg> oh... oh... I see.. they are using inlined math to geneate the spiral on the fly..
[02:30:23] <XXCoder> its initital nc loaded has scale
[02:31:48] <trentster> I think if your CAM software supports Smoothing, you can select it and choose a smoothing tolerance which will also help a lot for slowdown around corners
[02:32:08] <XXCoder> yeah I played with g40 and g41
[02:32:11] <XXCoder> it was interesting
[02:32:33] <jesseg> or just design your pattern with curved corners so it doesn't have to stop for each one :P
[02:33:04] <archivist> trentster, tormach sponsered the new TP in linuxcnc
[02:33:15] <trentster> archivist: oh cool
[02:34:08] <trentster> archivist: I saw awhile back you guys were going to get a pathpilot recovery cd and see if you could pull out the UI they are using. Did anyone make any progress with that?
[02:34:37] <archivist> I was not doing that
[02:35:02] <trentster> oh - it must have been someone else in the channel then, I remember reading it here
[02:35:23] <archivist> remember the gui is not open source
[02:35:47] <trentster> oh, I did not know that
[02:36:26] <XXCoder> nothing wrong with reverse engineering, or dveeloping gui thats similiar
[02:36:29] <archivist> the new "features" that will be in 2.8 will probably be as good if not better
[02:36:35] <trentster> some open source licences preclude improvements/enhancements without contributing it back
[02:36:47] <trentster> I guess the Ui does not fall into the "improvement" category
[02:38:35] <jesseg> Thanks guys! I'm off.
[02:38:50] <XXCoder> later
[02:38:55] <trentster> past your sell by date jesseg
[02:38:59] <trentster> ;-)
[02:42:42] <trentster> archivist: where do you read that Tormach sponsored a feature? Is there a site listing contributions?
[02:42:47] <trentster> or sponored work?
[02:42:51] <trentster> *sponsored
[02:44:01] <trentster> Also does Tormach bundle mesa cards by default with their machines?
[02:44:25] <archivist> google robert ellenberg linuxcnc
[02:46:36] <archivist> should pop up somewhere in linuxcnc-devel irc logs
[02:46:52] <trentster> thanks reading
[02:50:22] <trentster> archivist: in 2.7.2 is TP enabled by default or does one need to configure it and tell it how many steps to look ahead?
[02:51:05] <archivist> what does the manual say :)
[02:51:17] <trentster> Do you think if using a non mesa card and a standard parallel port will be effected by a look ahead setting
[02:51:36] <XXCoder> affected
[02:52:11] <trentster> XXCoder: was that a grammar correction for me?
[02:52:17] <XXCoder> yeah
[02:52:22] <trentster> thanks :P
[02:52:29] <XXCoder> welcome. :P
[02:52:31] <XXCoder> heh
[02:53:01] <archivist> look ahead is not in the external card
[02:54:07] <trentster> archivist: yup I understand that, was just wondering about the effect it has on a system if any. I presume the only thing that should be effected is a bit of extra CPU time
[02:56:44] <archivist> probably, depends how well written
[03:02:24] <justanotheruser> archivist: do you run /r/datahoarder?
[03:02:36] <XXCoder> the discussion about spirls made me wonder
[03:02:53] <XXCoder> wy not just add support for g2.1 abd g3.1
[03:02:58] <archivist> no idea what datahoader is
[03:03:20] <archivist> I hoard physical
[03:03:22] <justanotheruser> subreddit about having petabyte archives
[03:03:29] <justanotheruser> run by someone named archivist-
[03:03:31] <justanotheruser> nvm though
[03:03:56] <XXCoder> archivist is a word, easy enough for someone else to have same idea
[03:04:26] <archivist> I had it first!
[03:04:51] <archivist> it is funny how many things get re invented
[03:04:57] <XXCoder> yeah
[03:05:07] <XXCoder> some lady blogger reinvented xxcoder
[03:05:21] <XXCoder> my XXCoder means completely different though lol
[03:06:00] <justanotheruser> whats an xxcoder
[03:06:21] <XXCoder> in her case, dna. XX and shes a coder
[03:06:42] <XXCoder> in my case well I havent revealed mine in decades and dont plan to.
[03:07:10] <justanotheruser> are you born in '80 and a coder?
[03:07:30] <XXCoder> 80s lol I was a 80s kid yes
[03:07:39] <justanotheruser> so thats it?
[03:07:40] <trentster> For anyone reading this thread and wondering about the new Trajectory Planner in 2.7.x here is the answer. The new Trajectory Planner (TP) is on by default and the default look ahead moves setting is 50 moves
[03:07:46] <justanotheruser> its bastardized roman numerals?
[03:43:41] <gonzo__> XX are the expleatives you use when coding?!
[03:44:04] <archivist> trentster, here is a question for you, was there an automatic car transmission invented in the 1950sin Dural AU
[03:47:54] <trentster> archivist: no clue - only been living in AU for 8 years
[03:49:05] <archivist> was just an off chance q cataloguing some old slides title is Hydrostatic transmission, Rover car, Dural Australia
[03:49:34] <archivist> where is Valen :)
[03:49:43] <Valen> what what?
[03:50:01] <archivist> see above question :)
[03:50:27] <Valen> I do seem to recall something about some australian company manufacturing transmissions
[03:50:53] <Valen> if you are interested I know a guy with a pair of 70's rovers he may know more
[03:52:20] <archivist> that is the image, warning high res http://www.collection.archivist.info/searchv13.php?searchstr=ps3453
[03:52:59] <archivist> looks an experimental set up
[03:53:11] <Valen> dural is a town, so I'm guessing that is just the location it was taken
[03:53:24] <Valen> but I'll ask him
[03:53:36] <archivist> I am wondering if that was where the company was
[03:56:29] <Valen> facebooks says he has seen the message but I wouldn't hold out much hope of a reply today
[03:59:19] <archivist> no rush thanks
[03:59:40] <archivist> only had the slides for 20 years
[04:00:14] <XXCoder> just 20 years. man thats barely past new
[04:01:02] <gonzo__> just waiting for the internet to come of age so you can find someone to ask!
[04:01:15] <archivist> someone writing a book on Lucas's early jet engine work contacted me, have to complete the catalogue
[04:03:10] <Valen> archivist he doesn't know so he is going to ask at the rover club meeting on wed for you archivist ;->
[04:03:33] <SpeedEvil> archivist: neat
[04:05:26] <archivist> trouble is while cataloguing one finds other stuff to find out about
[07:27:24] <hiroshima5> hi there
[08:39:39] <Alexande1B> hi there
[08:40:26] <Alexande1B> I can set the position of an axis by "G10 L20 P0 X0", is there a way to automatically set ot to half the current value?
[08:41:34] <archivist> you can do maths in gcode
[08:46:21] <Alexande1B> Do you have an example?
[08:47:43] <Alexande1B> I can use "G10 L20 P0 A [5/2]" but how can I automatically use the current position of A instead of "5"?
[08:49:55] <cradek> http://www.linuxcnc.org/docs/html/gcode/overview.html#sub:system-parameters
[08:50:29] <cradek> I'm curious - why do you want this? I can't think of a use case.
[08:59:08] <Alexande1B> cradek: Thank you, it works now. I want to touch one side of a workpiece, set the value to zero, then touch the other side of the workpiece and divide the value by two. If I move to zero afterwards I have exactly the center of the workpiece
[09:29:31] <cradek> ah, cool, thanks for explaining
[09:34:20] <Roguish_> hey all. quick Linux question/problem. I have an ssd with 4 primary partitions occupying only about 1/2 the drive. of the four partitions, 2 are data/system and 2 are swap space. what would the best way be to handle this?
[09:34:53] <Roguish_> I want to end up with fewer than 4 primary partitions,
[09:36:16] <Roguish_> if I move and/or copy partitions around, will GRUB keep up?
[09:37:27] <cradek> you'll almost surely make it unbootable if you mess with it
[09:38:51] <Roguish_> isn't there a GRUB reconfigure or something?
[09:38:59] <cradek> what changes do you want to make?
[09:39:44] <cradek> I'm sure you could delete and change the two swaps
[09:40:23] <Roguish_> well, I would like to move another 'linux system' to the disk. I was building a kernel last evening and ran out of room on another very small ssd
[09:41:18] <cradek> you could probably delete a swap and install a third system in its place
[09:41:30] <Roguish_> so the larger ssd is 128g with about half unavailable now due to the 4 primary partitions.
[09:41:40] <Roguish_> that's sort of what i was thinking.
[09:42:24] <cradek> make backups
[09:43:04] <Roguish_> if i delete 1 of the swap, i could then create an extended in the larger blank area.
[09:47:09] <Roguish_> cradek: does this look ok? http://serverfault.com/questions/17718/how-do-i-change-swap-partition-in-linux
[09:47:48] <cradek> no
[09:48:10] <cradek> oh yeah, it does say "and edit fstab" so yes that advice is fine
[09:48:11] <Roguish_> oh. I see the date of 6 years ago. crap.
[09:48:31] <Roguish_> ok. thanks.
[09:49:10] <Roguish_> so if i get it. i could have several systems using the same swap partition, right?
[09:49:59] <cradek> yes I think that's fine
[09:50:11] <SpeedEvil> Roguish_: as long as they're not booted at once
[09:50:34] <Roguish_> oh, yeah. of course not.
[09:50:44] <Roguish_> cool, thanks guys.
[10:34:34] <zeeshan> man, i feel like i have a new mill!
[10:34:54] <zeeshan> last night i realized, my machine uses 1 limit switch for both +/- axis limit
[10:35:07] <zeeshan> and the home switch is in between the max and min limit. i gained 2" of travel.
[10:35:57] <zeeshan> 14.75" x,y -> 16.75" , z = 14.0" -> 16.75" , :DD:D:D
[11:03:54] <Erant> Any recommendations for where to get precision ACME rods?
[11:04:30] <Erant> I know McMaster has 'm, and they're actually reasonably priced, but I need the ends machined and I highly doubt they do that :P
[11:07:05] <archivist> have a lathe? do it yourself, or get a local machine shop to do it
[11:07:34] <Erant> No lathe yet, plus the X-axis would be too long to do in a small lathe.
[11:07:43] <Erant> Though, maybe, barely. It'd be 16" long.
[11:08:08] <zeeshan> if you need the ends machined
[11:08:16] <zeeshan> can't you just stick the screw through the spindle bore
[11:08:26] <zeeshan> and have it stick out like 3"
[11:09:06] * archivist whacks zeeshan to read the first 3 words of his reply :)
[11:09:39] <CaptHindsight> Erant: there are a couple of shops on ebay that sell ACME screws with machined ends
[11:10:02] <zeeshan> :D
[11:10:03] <CaptHindsight> BUT, only to certain lengths are in stock
[11:10:14] <archivist> one of the first tools in a workshop should be a lathe :)
[11:10:28] <Erant> Yeah, figures. I don't need them NOW, it's just that this machine has some weird-as-shit leadscrews.
[11:10:48] <zeeshan> i got a 16" long part that needs 2 8-32 tapped holes
[11:11:05] <Erant> archivist: Right, and I'm seriously considering getting one. I see now that there's a whole host of things that would be either impossible on my mill, or very very hard.
[11:11:21] <hiroshima5> does anybody know how to install a new glade component?
[11:11:25] <CaptHindsight> mill with live tooling
[11:11:57] <Erant> It's a 12mm leadscrew, but 20TPI.
[11:12:33] <archivist> for cnc you dont really care what the TPI / pitch is
[11:12:39] <Erant> So I'm eyeing a 1/2"-10 instead.
[11:13:03] <Erant> archivist: Well, I care in as so much that it's very hard to find anything that works with it.
[11:13:19] <ssi> get a cheap spin index
[11:13:19] <Erant> I might order a spare leadscrew and fashion a tap though...
[11:13:21] <archivist> you have no nut?
[11:13:36] <ssi> I actually do the bearing journals on ballscrews by spinning them in a spin index on my surface grivder
[11:13:38] <Erant> I have a nut, it's a shitty one. They're made out of steel.
[11:13:49] <archivist> this where you also need the lathe first...to make nuts
[11:14:04] <Erant> I want to replace it with delrin, along with the gibs.
[11:14:17] <Erant> Right... That'd be significantly easier.
[11:15:32] <CaptHindsight> Erant: what length do you need?
[11:15:54] <blib> looking for a small cnc to cut alum 3" x 3" x 3" space would do
[11:16:37] <Erant> CaptHindsight: 16", ish.
[11:16:54] <Erant> blib: Ready made, or a conversion? I just did a CNC conversion on a mill.
[11:17:16] <blib> Erant: preferably something that a newcomer/newbie can use/play with
[11:17:19] <blib> ready perhaps?
[11:18:15] <Erant> Depending on your speed/accuracy needs, you could try a CNC router, but I wouldn't recommend it.
[11:18:37] <blib> Erant: I need to cut some parts for a small robot
[11:18:54] <blib> Erant: http://www.carbide3d.com/ ?
[11:19:00] <ssi> something like a taig or x2 would work for you
[11:19:21] <Erant> blib: I mean, technically it would work.
[11:19:45] <blib> Erant: any other suggestions?
[11:20:05] <Erant> Not very fast though. I converted this guy: http://littlemachineshop.com/products/product_view.php?ProductID=4660&category=1387807683
[11:21:06] <Erant> Which can handle aluminium just fine.
[11:21:27] <Erant> There's always the Tormach personal CNC machines, but they'll run you +$6k
[11:21:53] <ssi> the difference between those machines is the X1 mill is going to cut aluminum well and struggle with steel, whereas those cheap flexy maker-class desktop routers are going to gut wood well and struggle with aluminum
[11:22:12] <zeeshan> lol ssi
[11:22:24] <ssi> zeeshan: do you disagree? :P
[11:22:39] <ssi> they'll both cut aluminum, for some values of cut
[11:22:46] <zeeshan> hell no
[11:22:49] <zeeshan> im suprised they cut wood
[11:22:51] <ssi> heheh
[11:23:08] <zeeshan> hey ssi, for your laser
[11:23:11] <archivist> can they manage paper
[11:23:16] <ssi> archivist: probably not
[11:23:16] <Erant> blib: Right. It's all down to the rigidity of the system.
[11:23:17] <zeeshan> how were you controlling power from linuxcnc?
[11:23:22] <ssi> paper is hard to cut with an edge tool :)
[11:23:30] <ssi> zeeshan: laser power?
[11:23:34] <zeeshan> ya
[11:23:35] <Erant> And those routers just aren't very rigid.
[11:23:38] <zeeshan> for rastering
[11:23:46] <zeeshan> and other fancy stuff :p
[11:23:54] <blib> Erant: how are the tormach reviews?
[11:24:44] <ssi> zeeshan: https://github.com/ianmcmahon/linuxcnc_configs/blob/master/laser/laser.hal#L165-L173
[11:24:45] <blib> apart from price
[11:24:58] <zeeshan> i cant open files right now
[11:25:01] <zeeshan> but can you please describe it
[11:25:05] <zeeshan> this guys power supply needs a ttl signal
[11:25:07] <ssi> the spindle speed output of the 7i76
[11:25:15] <zeeshan> do you need a 7i76
[11:25:18] <ssi> no
[11:25:25] <zeeshan> or can you directly do it over par port
[11:25:28] <ssi> my psu needed a 0-5v analog signal
[11:25:31] <ssi> could do it with pwm
[11:25:43] <zeeshan> i dont even understand how ttl works
[11:25:47] <Erant> blib: People like the Tormachs, I believe. They're semi-professional.
[11:25:49] <zeeshan> i just know it needs a specific output :P
[11:25:53] <ssi> ttl is just a voltage threshold range
[11:25:55] <ssi> 0 to 5v essentially
[11:26:01] <zeeshan> like the encoder inputs on mesa are ttl
[11:26:07] <ssi> but ttl more specifically defines the high and low transition thresholds
[11:26:12] <zeeshan> oh
[11:26:15] <ssi> ttl only makes sense in this case if it's a digital input
[11:26:20] <ssi> ie 0 power or max powahhhh
[11:26:27] <zeeshan> so there is no inbetween?
[11:26:27] <ssi> probably they say ttl when what they mean is 5v max
[11:26:29] <ssi> not the same thing
[11:27:00] <zeeshan> so basically youre saying
[11:27:03] <Erant> Yeah, TTL implies digital. (< 0.8v is off, > 2.5v is on)
[11:27:12] <Erant> Or somewhere around those voltage ranges.
[11:27:18] <zeeshan> if i give it 2.5V it should output 50% power
[11:27:25] <ssi> zeeshan: yes likely
[11:27:33] <zeeshan> but when they say ttl, 2.5V could mean ON 100% power
[11:27:38] <zeeshan> which doesnt make sense for a laser power supply
[11:27:42] <ssi> no, that doesn't make sense
[11:27:47] <Erant> It could
[11:27:49] <zeeshan> cause you want capability to vary the power
[11:27:50] <Erant> If it's a PWM input
[11:27:51] <ssi> and they're almost certainly using the term ttl incorrectly
[11:28:02] <zeeshan> okay if its pwm input
[11:28:10] <ssi> Erant: yeah but PWM is just a cheap way to do analog with a digital system
[11:28:20] <zeeshan> then the pulse duration and stuff coresspond to laser power
[11:28:25] <ssi> and if you use a 2.5V carrier and PWM it, you won't get the same values as if you use a 5V carrier
[11:28:27] <zeeshan> so like 10hz might mean 10% power
[11:28:31] <zeeshan> 50 hz might mean 50% power
[11:28:33] <zeeshan> etc
[11:28:41] <ssi> zeeshan: no, pwm is based on duty cycle, not frequency
[11:28:46] <Erant> zeeshan: Not so much the frequency, more the width of the pulse.
[11:29:13] <Erant> ssi: I've seen more than once where PWM is just the 'protocol'.
[11:29:23] <ssi> zeeshan: if you have a square wave of any frequency with a 50% duty cycle, the average voltage is going to be 50% of the carrier voltage
[11:29:28] <zeeshan> okay so the pulse will be defined ass 100% if its 50ms long, and if i pulse a wave at 25ms
[11:29:30] <ssi> Erant: yeah but I'd be shocked if this were the case
[11:29:33] <zeeshan> itll mean 50%
[11:29:36] <zeeshan> like car injectors
[11:29:52] <ssi> yeah basically
[11:30:09] <zeeshan> okay so my buddy isnt giving me proper info
[11:30:11] <ssi> almost certainly that supply wants an analog signal from 0 to 5v
[11:30:15] <zeeshan> i need to see if its an analog input
[11:30:15] <ssi> and pwm is a cheap way to do that
[11:30:16] <zeeshan> or pwm
[11:30:25] <zeeshan> can parport do pwm
[11:30:28] <ssi> yes
[11:30:37] <zeeshan> its a cheap system they want working
[11:30:39] <ssi> you ever mess with RC servos?
[11:30:46] <zeeshan> nope :/
[11:30:48] <ssi> ok
[11:30:52] <ssi> that's a system that uses pwm as a "protocol"
[11:30:57] <ssi> that's NOT what we're talking about here
[11:31:10] <ssi> we're talking about a way to vary the voltage of a digital output
[11:32:37] <zeeshan> yes
[11:33:01] <zeeshan> he currently has a 60w laser tube
[11:33:06] <zeeshan> and 2 steppers
[11:33:16] <zeeshan> was wondering how to control laer power
[11:33:20] <zeeshan> im gonna ask him for power supply link
[11:33:30] <ssi> something else to keep in mind is that the power isn't exactly linear with the voltage on that terminal
[11:33:41] <ssi> well it may be linear but it usually has an offset
[11:33:43] <zeeshan> and see what ths specs says in chinglish
[11:33:53] <zeeshan> ya but that can be fixed in linuxcnc?
[11:33:56] <ssi> yes
[11:33:58] <ssi> that's what I linked you
[11:34:01] <zeeshan> with the scale thing
[11:34:12] <ssi> and I set mine up so I didn't control it by power
[11:34:14] <ssi> but by current
[11:34:24] <ssi> the power and current are correlated, but not necessarily linearly either
[11:34:41] <CaptHindsight> I want to start an argument that the square wave isn't really square
[11:34:51] <zeeshan> youre a square capt
[11:35:00] <CaptHindsight> oh yeah
[11:35:00] <zeeshan> sponge bob
[11:35:01] <ssi> no square waves are really square :)
[11:35:06] <CaptHindsight> lol
[11:35:20] <ssi> because there's not enough energy spectrum to represent infinite slew :D
[11:36:20] * ssi makes up some more words
[11:36:42] <CaptHindsight> get all your US orders in today to see them before turkey day
[11:37:12] <ssi> god it's a super nice day out and I want to go fly but it's cold as balls
[11:37:22] <zeeshan> bah back to work
[11:37:24] <CaptHindsight> the UPS and Fedex drivers around here don't even bother stopping on Friday
[11:38:53] <CaptHindsight> we were down to 7F with 12" of snow saturday, turkey day is 60F
[11:39:28] <ssi> it's 44 here
[11:39:33] <ssi> that's downright arctic
[11:44:48] <Jymmm> Heh
[11:45:00] <Jymmm> 44 is "warm"
[11:45:23] <Jymmm> tshirt weather
[11:46:10] <Jymmm> Mind you, i would have never said that last year
[11:46:49] <Jymmm> It's the 30's and 20's that you start going DAMNNNNNNNNNNNN
[11:48:54] <ssi> the real problem is no heat in the apartment
[11:48:59] <ssi> it's 51 inside
[11:49:02] <ssi> and that suuuuucks
[11:49:06] <ssi> that's now, at noon
[11:49:11] <ssi> it was like 40 in here last night
[11:49:12] <Jymmm> Ah, yeah. Turn on the oven.
[11:49:28] <Jymmm> leaving the door open
[11:56:06] <ssi> should I stick my head in it while I'm at it?
[12:08:02] <CaptHindsight> appears to be a manually operated stepper motor controller http://www.automationtechnologiesinc.com/products-page/cnc-parts/stepper-motor-pulse-signal-generator
[12:08:30] <CaptHindsight> it still needs a driver
[12:08:56] <ssi> I've seen people use those for testing stepper systems
[12:09:06] <ssi> it'd be pretty limited in usefulness for real things
[12:09:15] <ssi> maybe if you just wanted a speed knob to run a stepper
[12:09:34] <pcw_home> metering pump or some such
[12:10:13] <CaptHindsight> it would be more handy is the pushbutton connections were also on headers
[12:10:18] <CaptHindsight> is/if
[12:10:31] <CaptHindsight> nothing a soldering iron can't handle
[12:11:05] <ssi> build a robot that can measure the position of the axis the stepper is attached to, and a gripper on the knob, and uses a pid loop to mechanically turn that knob to maintain stepper velocity in order to keep the axis in the commanded position
[12:17:34] <maxcnc> ssi: the steppers are good if your system is good here i got no servo at all and no hybrid in use and it works since years
[12:17:53] <ssi> huh?
[12:18:12] <maxcnc> Limited use of steppers
[12:19:04] <maxcnc> i id read the log
[12:19:34] <ssi> you have a machine controlled by steppers that are run by a pulse generator with a manual knob, and you built a robot that senses the position of your axes and uses a fancy robot hand to turn the knob to close the loop?
[12:19:37] <maxcnc> here in Germany where i am its going below -10 Ctonight
[12:19:39] <ssi> cause if so I'm impressed
[12:20:25] <maxcnc> no my understanding in Eng. is very limited i see
[12:21:29] <maxcnc> im always wrong in ansering i see :-(
[12:21:38] <ssi> ha no it's ok
[12:21:43] <ssi> I'm just being stupid
[12:22:23] <maxcnc> pcw_home: today i got the Ferrit elements and the shielding orderd on your advice and i got faults but no breakdown
[12:22:34] <CaptHindsight> controlled by an arduino for less points
[12:23:08] <maxcnc> ssi: there are horrabel mashine setups out in the world
[12:23:34] <ssi> indeed
[12:23:45] <maxcnc> Alexande1B: are you on ?
[12:24:58] <CaptHindsight> ssi: it's funny by some paper slitters speed controllers operated similarly, they had mechanical potentiometers on a gear system to turn down the voltage to the motor drive
[12:25:21] <ssi> oh I know
[12:25:57] * ssi is elbows deep in servosyn remote tachometers at the moment
[12:26:23] <ssi> yay 60s tech
[12:26:27] <maxcnc> CaptHindsight: are you a wizard i demonted sutch one today to get to the paper slize holder
[12:28:36] <maxcnc> Folks is there a good totourial about Halmeter with all this gains and timing i need to overcome this as i more and more need the inputs to be watched what happens
[12:31:12] <CaptHindsight> Hal meter or scope?
[12:31:23] <maxcnc> sorry Halscope
[12:32:03] <maxcnc> reading http://linuxcnc.org/docs/html/hal/tutorial.html#sec:tutorial-halscope
[12:32:14] <CaptHindsight> you found it
[12:33:53] <Jymmm> 4 channels? 16 channels? Is that a virtual thing?
[12:34:08] <Jymmm> oh nm
[12:37:33] <hiroshima5> how could I install a new glade hal component
[12:38:04] <hiroshima5> I want to modify lightbutton for example
[12:45:12] <maxcnc> hiroshima5: did you read this linuxcnc.org/docs/html/gui/gladevcp.html
[12:45:31] <hiroshima5> yes maxcnc
[12:45:45] <hiroshima5> but it only explain how to reinstall in rip installation
[12:45:57] <hiroshima5> no says anything about system-wide one
[12:47:15] <maxcnc> 3.1 does say its systemwide
[12:49:52] <maxcnc> as i read and understand there is all in this docu what you need to get to what you want
[12:50:15] <maxcnc> that wars hard to build this sentence
[12:50:39] <hiroshima5> maxcnc i mean the point 12
[12:50:46] <hiroshima5> custom widgets
[13:44:53] <Erant> I love as-is bins. Scored a 25"x10"x3/4" piece of HDPE for $15.
[13:45:26] <Erant> Time to go cut some more enclosures
[13:45:56] <Tom_itx> go make it snow
[14:01:46] <JT-Shop> shut your mouth Tom_itx
[14:22:36] <Erant> Tom_itx: Haha, I'm glad I'm not the only one that thinks it looks like that :)
[14:22:57] <Erant> I got some black HDPE this time actually, so.
[14:45:26] <FinboySlick> Bold claim: https://www.kickstarter.com/projects/738022267/the-most-rigid-3d-delta-printer-ever-built-modular
[15:15:17] <_methods> is it made from balsa wood
[15:17:31] <Sync> http://sync-hv.de/projects/3phase_troller/frrrrp.mp4 amaze.
[15:18:44] <SpeedEvil> Balsa can actually be very, very rigid for a 3d printer
[15:32:35] <XXCoder> bamboo
[15:39:37] <zeeshan> andypugh: hi
[15:39:41] <zeeshan> hi pete
[15:42:07] <XXCoder> hey zeeshan
[15:42:14] <zeeshan> hi coder! :D
[15:42:20] <XXCoder> whats up
[15:43:49] <PetefromTn_> hello zeeshan
[15:44:09] <zeeshan> hows everything pete
[15:44:14] <zeeshan> havent seen you talk much
[15:44:20] <zeeshan> busy machining? :D
[15:44:24] <PetefromTn_> everything is okay
[15:44:31] <PetefromTn_> have a lot of stuff going on lately
[15:44:40] <PetefromTn_> got a bunch of parts to machine
[15:44:51] <PetefromTn_> trying to get some work done on the CNC lathe build
[15:45:12] <PetefromTn_> hoping to get a bunch done over the holiday weekend
[15:45:38] <zeeshan> nice
[15:45:49] <zeeshan> dont you guys have black friday this weekend
[15:45:52] <zeeshan> well friday :p
[15:46:03] <PetefromTn_> yeah I guess so
[15:46:07] <XXCoder> https://www.youtube.com/watch?v=5rQ4xKRfXts geez
[15:46:21] <PetefromTn_> I honestly don't think I have ever shopped on that day in my life
[15:46:29] <XXCoder> guys probably poor though so its pretty awesome hes making do
[15:46:31] <zeeshan> haha
[15:46:37] <zeeshan> apparently electronics are cheap
[15:47:00] <PetefromTn_> you gotta be kiddin me
[15:47:07] <zeeshan> i want to get a new computer for the mill
[15:47:15] <zeeshan> i cant stand how painfully slow it is
[15:47:18] <zeeshan> drives me insane
[15:47:27] <XXCoder> zeeshan: go to computer recycling center
[15:47:30] <XXCoder> save a pc
[15:47:37] <zeeshan> haha
[15:47:43] <zeeshan> no! thats what i did with this
[15:47:46] <zeeshan> i picked my old comp
[15:47:50] <PetefromTn_> what kind of PC did you use?
[15:47:56] <zeeshan> from like 2003
[15:48:05] <zeeshan> athlon xp 3200+
[15:48:15] <zeeshan> it used to run quake pretty fast! :D
[15:48:32] <PetefromTn_> man I could not watch that video more than a minute or two
[15:48:38] <XXCoder> my cnc pc is from 2005
[15:49:02] <XXCoder> PetefromTn_: why?
[15:49:32] <PetefromTn_> other than the very occasional real time error I have been happy with the D525 atom on the Cinci. curious as to how this new board and chip will work
[15:49:45] <PetefromTn_> is that your machine?
[15:49:49] <XXCoder> lol no
[15:49:58] <PetefromTn_> is it anyone here
[15:50:10] <XXCoder> probably not but dunno
[15:50:31] <PetefromTn_> well it is far and away one of the biggest pieces of shit I have ever laid eyes on then ;)
[15:50:39] <greg> I was updating to 2.702 on the ~1999 pc I'm going to run the lathe on
[15:50:41] <XXCoder> it is
[15:51:00] <greg> painful to watch that vid
[15:51:11] <PetefromTn_> greg agreed
[15:51:22] <XXCoder> its always interesting to see someone make do with crappy resources
[15:51:27] <PetefromTn_> amazing he had the balls to actually make a video about it LOL
[15:51:43] <XXCoder> wow alum cut is shit
[15:51:44] <malcom2073_> Haha oh man, he's running homemade servos
[15:51:46] <malcom2073_> like, totally homemade
[15:51:56] <malcom2073_> random DC motor + hand cut encoder wheel
[15:52:11] <malcom2073_> That's actually pretty awesome
[15:52:19] <PetefromTn_> I love the eccentrics in the screw/motor interface
[15:52:28] <PetefromTn_> I suppose that is for harmonics
[15:52:50] <XXCoder> we are free to share his video
[15:52:52] <XXCoder> like we will
[15:52:59] <greg> I think he makes money from youtube clips
[15:53:29] <greg> ~20k subscribes must amount to something
[15:53:40] <SpeedEvil> Not much at all
[15:53:51] <PetefromTn_> how the hell do you MAKE money from youtube vids?
[15:53:57] <malcom2073_> PetefromTn_: Adverts
[15:54:04] <XXCoder> dunno so far I only uploaded 2 videos. probably total of 200 views or less lol
[15:54:20] <SpeedEvil> http://socialblade.com/youtube/youtube-money-calculator
[15:54:30] <XXCoder> that crappy machine guy is one of rare guys that caption videos
[15:54:30] <SpeedEvil> $810.00 - $12,960.00
[15:54:30] <SpeedEvil> Estimated Yearly Projection
[15:54:43] <SpeedEvil> (the latter is extremely unlikely)
[15:55:09] <malcom2073_> PetefromTn_: He cuts underwater later in the video
[15:55:24] <greg> only three times what I make
[15:55:41] <XXCoder> malcom2073_: yeah. plastic etching under water
[15:55:46] <greg> etching
[15:55:48] <greg> lol
[15:55:51] <PetefromTn_> I have a bunch of videos on youtube and never made a cent LOL
[15:55:59] <malcom2073_> PetefromTn_: Have you signed up to make cents?
[15:56:01] <XXCoder> PetefromTn_: not enough eyes
[15:56:13] <PetefromTn_> heh was not aware I had to SIGN up for it
[15:56:16] <XXCoder> oh signup required?
[15:56:25] <malcom2073_> Yeah, you gotta give them your social security number or tax id, etc etc
[15:56:41] <XXCoder> interesting. if I ever make something thats popular, I will.
[15:56:48] <greg> yeah i get a 1099 from google
[15:56:54] <PetefromTn_> https://www.youtube.com/channel/UCFCopiUpaDrS5VBkrYFuGFQ
[15:56:58] <PetefromTn_> thats my schtuff
[15:57:29] <XXCoder> https://www.youtube.com/watch?v=AC3BqPe7L7U&list=TLrWwTwRBz2qgyMzExMjAxNQ
[15:57:36] <XXCoder> pretty cool. and he captions videos!
[15:58:08] <PetefromTn_> I captioned my videos
[15:58:14] <PetefromTn_> and added nice music
[15:58:17] <PetefromTn_> ;)
[15:58:21] <XXCoder> lol
[15:59:30] <PetefromTn_> https://www.youtube.com/watch?v=I4TxQYivMjo
[16:00:07] <greg> the detail is impressive
[16:00:31] <XXCoder> he uses mother's alum polish too
[16:00:34] <XXCoder> I love that stuff
[16:03:11] <XXCoder> his machine is pretty cool
[16:03:28] <zeeshan> haha i just read a cool article
[16:03:41] <zeeshan> the successful drill rig out of the like 10
[16:03:49] <zeeshan> was the one w/ eaton pumps, motors, valves, hoses, hose fittings
[16:03:59] <zeeshan> that rescued those 33 miners trapped in chile
[16:04:03] <zeeshan> :D
[16:07:30] <XXCoder> PetefromTn_: autocaption dont count lol
[16:07:33] <zeeshan> watch that movie "33"
[16:07:36] <zeeshan> its good!
[16:07:55] <PetefromTn_> what autocaption?
[16:08:14] <XXCoder> you said you captioned all videos
[16:08:21] <XXCoder> but only option I see is autocaption
[16:09:14] <PetefromTn_> I never said I captioned ALL videos but I certainly captioned a bunch of it
[16:09:27] <XXCoder> ah you didnt say all indeed
[16:09:32] <XXCoder> assumation on my part lol sorry
[16:09:43] <PetefromTn_> Oh you mean CLOSED CAPTION because you are deaf LOL
[16:09:51] <PetefromTn_> I just remembered
[16:09:55] <PetefromTn_> yeah sorry
[16:10:08] <XXCoder> no worries
[16:10:12] <PetefromTn_> but I did add a lot of text and whatnot to describe what was going on
[16:10:19] <XXCoder> that does help
[16:10:42] <XXCoder> one of stranger satistics on captions is that 80% of users isnt deaf
[16:11:50] <Tom_itx> haha zeeshan i've got 2 of those pc's sitting here
[16:12:17] <XXCoder> I have seen people say "bah not worth captioning for 1 or 2 deaf out there" when its hardly even majority of caption users
[16:13:00] <XXCoder> PetefromTn_: I dont even care about accuracy (exactly words you use) as long as meaning is same
[16:13:21] <PetefromTn_> https://s-media-cache-ak0.pinimg.com/originals/2a/37/81/2a3781185eb0763a632a17ac62ba02d9.jpg WOAH MOMMA
[16:13:47] <Tom_itx> put your tongue back in your mouth
[16:13:55] <PetefromTn_> now that's a nice grocery getter ;)
[16:13:57] <Tom_itx> and clean up all that drool
[16:14:00] <XXCoder> and hands out of pants
[16:14:02] <malcom2073_> PetefromTn_: http://static1.squarespace.com/static/52d6c427e4b09a1f1b092149/t/5339876ae4b05968caf71588/1396279148688/Hendrick+Military+Jeep
[16:14:09] <malcom2073_> We have a bunch of those at my work, we helped build them
[16:14:14] <malcom2073_> You'd love them
[16:14:21] <malcom2073_> Turbo diesel fwiw
[16:14:35] <XXCoder> https://www.youtube.com/watch?v=tyxgYFTkR_M&feature=em-subs_digest-g
[16:14:39] <PetefromTn_> looks neat but I am not a huge jeep fan are they going to iraq or something?
[16:14:45] <XXCoder> pretty awesome. too bad no weilding and building skills lol
[16:14:59] <Tom_itx> if they came with all the acessories i'd use one in traffic
[16:15:01] <malcom2073_> We deployed them to afghanistan, but most of them are just used for scooting around here in the US heh
[16:15:36] <PetefromTn_> is that a saw?
[16:15:39] <andypugh> zeeshan: I was in the workshop
[16:15:49] <Tom_itx> malcom2073_, hendrix aka Rick Hendrix?
[16:16:13] <andypugh> One of my Youtube videos has 143,000 hits. I could have been a hundredaire!
[16:16:39] <malcom2073_> Tom_itx: Hendrick Automotive yeah
[16:16:40] <PetefromTn_> I have never even checked to see how many hits I have LOL
[16:16:53] <Tom_itx> he's got his act together
[16:16:56] <XXCoder> I just checked. 201 total views on 2 videos lol
[16:17:16] <malcom2073_> It was the motorsports division that worked on it with us
[16:17:26] <Valen> I use captions on the tv from time to time
[16:17:36] <Valen> if I have the volume low, or if I cant understand a word
[16:17:48] <malcom2073_> I was impressed working with them, they know their shit. I also know I never *ever* want to work for that company. too freaking cutthroat heh
[16:17:58] <XXCoder> lol
[16:18:00] <XXCoder> Valen: nice
[16:18:11] <Tom_itx> i've been thru their shops in NC a couple times
[16:18:27] <PetefromTn_> heh one of my vids has like 4300 views!
[16:18:31] <Tom_itx> they want the very best
[16:18:39] <malcom2073_> I had to pass on a chance to go down to their shop in NC, I had too much other stuff going on heh
[16:18:45] <malcom2073_> But the guy that went said it was nice
[16:18:53] <Tom_itx> first class op
[16:18:57] <andypugh> My YouTube stats are almost respectable: 393 subscribers • 338,708 views
[16:18:58] <malcom2073_> yeah
[16:19:04] <Tom_itx> stewart haas is nice too
[16:19:24] <Tom_itx> not as big
[16:20:57] <PetefromTn_> I have like 43 subscribers
[16:23:03] <PetefromTn_> 20222 total views ;)
[16:24:40] <FinboySlick> Oh cool, Pete's TN accent in all its glory!
[16:25:17] <FinboySlick> 41, pete. You lost zeeshan and Tom.
[16:25:43] <PetefromTn_> oh yeah
[16:25:51] <PetefromTn_> was not aware you can loose people LOL
[16:26:03] <PetefromTn_> but not surprised I lost those two jackholes ;)
[16:26:22] <FinboySlick> Well, off to dinner I go.
[16:26:36] <FinboySlick> You all try to behave yourselves like civilized people while I'm gone.
[16:27:58] <Tom_itx> i'm not even sure how visible mine are
[16:38:05] <greg> https://youtu.be/QwoghxwETng?t=1m26s
[17:06:32] <Deejay> gn8
[17:26:47] <JT-Shop> my deer only have to avoid gun hunters for one more day :)
[17:37:39] <zeeshan> andypugh: still there? :D
[17:37:41] <zeeshan> or in the shop
[17:38:13] <andypugh> Back here. I decided it was too late to start making gears.
[17:38:29] <zeeshan> hehe
[17:38:34] <zeeshan> have you done strength analysis?
[17:38:40] <zeeshan> or mostly controls at work
[17:39:54] <andypugh> What do you mean by strength analysis?
[17:40:02] <zeeshan> like finite element
[17:40:27] <andypugh> Yeah, I have done a bit, but it has never been a super-large part of my job.
[17:40:36] <zeeshan> for example, imagine two large plates, one has a circle hole
[17:40:39] <zeeshan> another has a square hole
[17:41:00] <zeeshan> there is a stress concentration and also a singularity (from FEM perspective)
[17:41:20] <zeeshan> if you apply a relatively low force, the square hole plate will yield locally at the corners almost instantly
[17:41:41] <zeeshan> i am trying to find some sort of design guideline which talks about when it's okay to have localized plastic deformation
[17:41:43] <zeeshan> and when its not
[17:41:49] <zeeshan> cant find anything!
[17:43:06] <andypugh> In practice, the square corners are not square
[17:43:28] <zeeshan> assume they are :P
[17:43:46] <andypugh> It might be instructive to see how large the radius needs to be before there is no plastic deformation.
[17:43:49] <zeeshan> the point im tryying to make is if the overall plate is seeing 200MPa
[17:43:59] <zeeshan> the localized corners will be seeing like 2000MPa
[17:44:05] <zeeshan> if you keep on trying to resolve it :P
[17:44:09] <zeeshan> because the area is technically infinite
[17:44:13] <zeeshan> so the stress is infinite
[17:44:19] <andypugh> Plastic defornation is not unusual in bolted connections.
[17:44:46] <zeeshan> thats true
[17:46:02] <andypugh> Your theoretical infinitely sharp corners are seeing a theoretical infinite stress. I think you need to consider the real case, before you worry.
[17:46:17] <Valen> +1
[17:46:19] <zeeshan> lets say in real life
[17:46:24] <zeeshan> the corner radius is 4 thou
[17:46:31] <zeeshan> its still a huge stress concentration
[17:46:45] <zeeshan> and you will yield the material
[17:47:23] <Valen> My understanding was FEA didn't generally work well when you started to actually deform the material
[17:47:33] <andypugh> This is only really a problem if there is cyclic stress, and/or stress reversal.
[17:47:56] <zeeshan> Valen: your understanding is incorrect!
[17:48:23] <andypugh> Valen: I think you are right that an elastic analysis wil be incorrect
[17:48:29] <zeeshan> if you try to use linear elasticity models with FEA, then its not going to work
[17:48:37] <zeeshan> you gotta use inelastic models, which is very common
[17:49:11] <Valen> you would have to progressivley simulate the deformation
[17:49:25] <Valen> as the geometry changes
[17:49:49] <andypugh> zeeshan: You can always pretend that the deformed material doesn’t exist, except as a spacer.
[17:50:13] <zeeshan> andypugh: i know like for sharp corners, you cant rely on fea there
[17:50:15] <zeeshan> cause its a singularity
[17:50:21] <zeeshan> but in real life, the simulations ive run
[17:50:38] <zeeshan> ill have like a 5"x5" bracket with 2" 1" f langes
[17:50:41] <zeeshan> 2x i mean.
[17:51:00] <andypugh> I am not sure that is true. Every corner node in the mesh is as much of a singularity as your square corner.
[17:51:10] <zeeshan> and around 1/16" of it on the inner radius,there is a massive stress riser that is of particular interest
[17:51:18] <zeeshan> because it lies between the yield strength and uts of the material
[17:51:28] <zeeshan> but the rest of the material is 2 times safer when compared with the ys
[17:52:24] <zeeshan> andypugh: if you do a fine enough mesh
[17:52:26] <andypugh> If you want to. you could look at the K1c etc.
[17:52:29] <zeeshan> it'll become a singularity :P
[17:53:26] * zeeshan goes into whining mode
[17:53:30] <zeeshan> the more i use inventor, the more it hurts
[17:53:47] <zeeshan> it forcefully uses p-refinement for 2-3 iterations
[17:53:48] <zeeshan> you cant disable it
[17:54:02] <zeeshan> i cant plot the stress distribution along a section!
[17:55:27] <andypugh> I see Inventor FEA as a design tool to show if you need to do a proper analysis with a “real” FEA package
[17:55:46] <zeeshan> i agree, it works for that
[17:55:58] <zeeshan> but dude, if the operator has no idea fea is
[17:56:10] <zeeshan> and tries to use it, they will start thinking their results are good
[17:56:18] <zeeshan> the standard simulation on inventor converges in 1 shot
[17:56:19] <zeeshan> lol
[17:56:25] <zeeshan> and gives you false results
[17:56:31] <zeeshan> ive done this on like 8 different parts at work
[17:56:40] <zeeshan> the stresses are significantly wrong
[17:56:46] <andypugh> brb, eating
[18:06:51] <malcom2073_> Tbh, if the operator has now idea what most anything is, and tries to use most anything thinking their results are good, bad things happen :P
[18:10:13] <zeeshan> malcom2073_: i made that comment
[18:10:24] <zeeshan> because a lot of my friends tell me "FEA class was bs, you dont learn shit"
[18:10:33] <zeeshan> and the last 2 weeks ive been doing simulation
[18:10:40] <zeeshan> if i didn't do that class, i'd be lost
[18:10:50] <malcom2073_> Lol, well at least you know never to hire them?
[18:11:15] <zeeshan> yes it doesn't teach you how to do practical simulation, but it teaches you to learn how to identify when things are wrong, and when you read things, and people are like "p-refinement " h refinement blah blah
[18:11:26] <zeeshan> you know what changing the order of the polynomial functions are
[18:11:30] <zeeshan> thats true :P
[18:11:32] <SpeedEvil> zeeshan: math is hard.
[18:11:49] <zeeshan> i hope youre being sarcastic :P
[18:11:53] <SpeedEvil> zeeshan: A _hell_ of a lot of people just give up when faced with math, when in principle it could solve their problems.
[18:11:53] <zeeshan> i dont have a read on you
[18:11:55] <SpeedEvil> No.
[18:12:10] <SpeedEvil> For example - resonance/stability problems
[18:12:15] <zeeshan> math was the easiest stuff ive done!
[18:12:17] <zeeshan> you know whats hard?
[18:12:20] <zeeshan> technical writing!
[18:12:37] <SpeedEvil> most people, even with nominal math skills - will avoid doing stability analysis when faced with ...
[18:12:53] <zeeshan> like youre talking 2nd order differential equations
[18:12:56] <zeeshan> used for vibrations
[18:13:09] <zeeshan> like mx"+cx' + kx = sin(wt)
[18:13:11] <SpeedEvil> I was thinking more involved stuff
[18:13:23] <SpeedEvil> For example, air bearing stability
[18:13:44] <zeeshan> thats kmore complex problem though i'd think
[18:13:53] <zeeshan> cause you'd need to setup your continuity and momentum equations for it
[18:14:16] <zeeshan> then i have no idea how the heck you'd get vibration output from that :P
[18:14:35] <SpeedEvil> I stalled out about semester 4 of a CS/math/physics degree due to health readons
[18:14:55] <zeeshan> are you okay now
[18:15:12] <zeeshan> getting sick sucks :/
[18:23:49] <SpeedEvil> No.
[18:25:08] <tsingi> But, but, math is hard!
[18:25:47] <zeeshan> sorry to hear that SpeedEvil
[18:26:33] <tsingi> SpeedEvil: Got CNC working. 4hp router. Woot! Learning gcode.
[18:27:24] <SpeedEvil> :)
[18:27:43] <SpeedEvil> tsingi: I forget what this was - wood?
[18:27:47] <SpeedEvil> For routing
[18:29:55] <tsingi> I think any CNC with a 4hp router will do metal. Anyway, ballscrews, I think we can expect 0.005" accuracy or better.
[18:30:44] <tsingi> SpeedEvil: I just realized what sub we were on, heh.
[18:31:04] <SpeedEvil> :)
[18:31:12] <tsingi> You have a CNC?
[18:32:11] <SpeedEvil> I have some parts that I intend at some point in the future to assemble into one
[18:33:14] <tsingi> I have two broken ones. Actually the big one only needs the touchpad hooked up properly and we're there.
[18:35:03] <SpeedEvil> :)
[18:35:16] <SpeedEvil> This is in the form of sheets of ply still.
[18:36:24] <yasnak> anyone else ever programmed the siemens 840di?
[18:38:10] <tsingi> SpeedEvil: A buddy made a plywood one that works very well. He's iterating up, I think he's on his third generation.
[18:38:26] <SpeedEvil> yeah - plywood is _lots_ less stiff than steel.
[18:38:26] <malcom2073_> I've been thinking about starting with a plywood one and working my way up for my big router
[18:38:48] <SpeedEvil> But - even if it's a hundredth as stiff, 7 times the section, and you've got it as stiff again
[18:38:56] <malcom2073_> It would be stupid silly, but I could use my rails on plywood, they're more stiff than the wood heh
[18:39:10] <SpeedEvil> And that assumes you don't also grow it on the other axis
[18:41:00] <tsingi> I misunderstood your wood question, no the big one has a ~4'x5' aluminum table. The other one is a small milling machine conversion 0.5hp, need a new ballscrew for it.
[18:41:22] <Sync> zeeshan: find me two yaskawa 50W servos
[18:42:06] <yasnak> haha
[18:42:11] <yasnak> funny you say that :P
[18:42:26] <PetefromTn_> 50 watt?
[18:44:49] <Sync> yep
[18:46:36] <jdh> ssi?
[18:47:39] <zeeshan> lol
[18:48:41] <Sync> http://sync-hv.de/projects/3phase_troller/frrrrp.mp4 zeeshan
[18:49:18] <zeeshan> did you pull that off a tormach?
[18:49:33] <zeeshan> :D
[18:50:00] <zeeshan> yasnak: what do you need to know about the sinumerik
[18:50:44] <Sync> yes zeeshan
[18:50:50] <zeeshan> :D
[18:51:10] <yasnak> zeeshan: how can I nuke it?
[18:51:18] <zeeshan> what do you mean :P
[18:51:43] <yasnak> hate this control
[18:51:47] <zeeshan> why
[18:51:49] <zeeshan> its awesome
[18:52:10] <zeeshan> you know there is a simulator online for it right?
[18:52:16] <zeeshan> so you can train
[18:52:17] <yasnak> where?
[18:52:29] <Sync> I just like the super small size of the servo
[18:52:37] <yasnak> i use step 7
[18:52:42] <Sync> and it actually works well
[18:52:54] <zeeshan> yasnak: https://www.industry.siemens.com/topics/global/en/cnc4you/cnc_downloads/Pages/cnc-downloads.aspx
[18:52:57] <zeeshan> look here
[18:52:58] <zeeshan> sinutrain
[18:53:11] <yasnak> but mostly do everything by hand, heh. we have two 16 axis swiss screw machines with the 840di
[18:53:28] <yasnak> oh yeah, thats cool
[18:53:40] <yasnak> if your machine hasn't been smacked around and ran to shit in production :P
[18:54:20] <zeeshan> it seems like a lot of the european built machines like to use sinumerik
[18:54:23] <zeeshan> for the fanuc
[18:54:41] <yasnak> hmm, i've got fanuc on our citizens
[18:54:47] <yasnak> and most of the star's
[18:55:27] <yasnak> but two stars have the 840di yaskawa siemens control. each time i have a drive, servo, controller issue its like shooting yourself in the foot to get someone to help
[18:55:56] <Sync> yaskawa siemens sounds really strange
[18:56:04] <Sync> usually they run indramat
[18:56:12] <zeeshan> yasnak: send me some machines
[18:56:14] <zeeshan> :D
[18:56:47] <yasnak> these are the bastards: http://www.starcnc.com/products/ECAS-1220.html
[18:57:53] <zeeshan> okay its time to start night job

[18:58:14] <__rob> anyone ever used one of these, http://www.avagotech.com/products/motion-control-encoders/absolute-encoders/single-turn-encoders/aeat-9000-1gsh1
[18:58:42] <__rob> seems almost impossible to align!
[18:58:54] <andypugh> __rob: I was about to say that someone was on here a few days ago with them. But I think that was you,
[18:59:20] <__rob> yea
[18:59:32] <greg> me too
[18:59:46] <Sync> don't need the drive andypugh, but yeah, I forgot to look in the uk ebay
[18:59:54] <__rob> the tolerances are pretty small
[19:00:08] <__rob> wonding if I can get a complete unit of that resolution thats cheap
[19:00:13] <andypugh> That’s actually FA-Parts in Korea. His prices are good, and Paypal cover the risks…
[19:00:45] <andypugh> __rob: There is probably an alignment jig.
[19:01:01] <__rob> this thing specs,
[19:01:02] <__rob> Radial : +/-50 mm (inclusive shaft eccentricity)
[19:01:02] <__rob> Tangential : +/-100 mm (inclusive shaft eccentricity)
[19:01:02] <__rob> Gap : 150 to 300 mm
[19:01:14] <__rob> theres a kit - $1000
[19:01:15] <__rob> lol
[19:01:35] <andypugh> __rob: You don’t mean mm.
[19:01:37] <__rob> where that says mm
[19:01:41] <__rob> is a bad paste
[19:01:45] <__rob> thats um
[19:02:03] <greg> I ordered a servo motor from korea. included a bunch of face cream samples in the box with the motor. i was wtf?
[19:02:08] <andypugh> Is there a picture of the kit?
[19:02:10] <Sync> I mean, that's not too hard
[19:02:19] <yasnak> haha
[19:02:39] <__rob> http://docs.avagotech.com/docs/AV02-3143EN
[19:02:42] <jdh> I got a silverware/chopstick set with my chinese router
[19:02:44] <__rob> thats the alignment kit
[19:03:00] <yasnak> if only they'd accidently pack beer :(
[19:03:34] <PetefromTn_> lol
[19:03:41] <__rob> http://docs.avagotech.com/docs/AV02-3236EN
[19:03:44] <andypugh> Something I got had some action figures in. But that was from the UK, and I thing a small child had “posted” them through the handhold hole in the box while it was waiting to go to the Post Office.
[19:03:46] <__rob> thats the "alignment process"
[19:04:02] <__rob> not sure if this should be achievable
[19:04:05] <__rob> or if I am wasting my time
[19:04:19] <__rob> they make it look dead easy
[19:04:41] <Sync> I like how some are selling the yaskawa raw encoders andypugh
[19:04:48] <Sync> which are basically useless
[19:04:54] <Sync> as they need to be aligned to the shaft
[19:05:06] <Sync> because they do commutation with them
[19:05:49] <andypugh> Sync: Well, if you use the LinuxCNC “bldc” component you can set the offset in software :-)
[19:06:45] <greg> it has multiple tracks so the head needs to be aligned?
[19:06:49] <andypugh> __rob: It looks like something that you could possibly do with a normal oscilloscope
[19:07:02] <__rob> yea, I think the big issue at the moment is my jig
[19:07:12] <andypugh> Or, possibly, Halscope.
[19:07:37] <zeeshan-mill> its crazt how much an extra 2" of travel helps
[19:07:43] <Sync> andypugh: or if I use my own driver that does that for me
[19:07:51] <andypugh> Have you talked to Avago? It is not inconcievable that they rent-out the kit, or offer a fitting service.
[19:08:05] <__rob> not yet, I will do if I cant get this working myself
[19:08:43] <andypugh> Sync: “bldc” counts as my own driver :-)
[19:08:43] <Sync> __rob: it does not look unreasonable
[19:08:51] <__rob> one thing, before I mill a proper jig, is how to add the adjustment for alignment
[19:09:08] <__rob> I was going to mill bearing pockets
[19:09:15] <__rob> and slot the axle through
[19:09:52] <__rob> guess undersize screws for the actual encoder
[19:09:55] <__rob> and clamp it down
[19:10:09] <__rob> but the adjustments are tiny
[19:10:41] <__rob> not really a fingers and thumbs job to shift it around as I can see.. there must be something I'm missing
[19:10:48] <andypugh> __rob: You can do tiny adjustments by hand. Just not repeatably. But you only need to get it right once.
[19:12:07] <__rob> alright, I'll give this a proper go
[19:12:12] <__rob> you've encouraged me
[19:13:47] <__rob> maybe its worth getting some precision bearings too
[19:13:52] <andypugh> I suspect it just needs patience.
[19:14:07] <__rob> jsut got some standard skf ones at the moment
[19:14:18] <andypugh> Commercially they probably don’t use patience, but patience is cheaper.
[19:14:41] <Sync> why would you need precision bearings?
[19:14:43] <andypugh> I doubt that the bearings have 0.05mm clarance.
[19:14:52] <Sync> if your bearing has more than 5/100mm clearance you are fucked
[19:15:24] <__rob> you think cheap bearings should be alright ?
[19:15:44] <andypugh> Look at the specs, they list RIC
[19:15:57] <DaViruz> http://www.ebay.com/itm/FANUC-PPR-Tape-Puncher-Unit-A13B0117B001-A13B-0117-B001-/151148791681?hash=item23312b8781:g:m8IAAOxyg7xSZdUP
[19:16:10] <DaViruz> im quite curious to see if he manages to sell it att that price
[19:16:34] <andypugh> I am wondering the same about: http://www.ebay.com/itm/Vintage-Esso-Brass-Plastic-Oil-Can-Antique-Oiler-Tractor-Truck-Farm-8703-/201027270790?hash=item2ece28b886:g:x80AAOxyOlhS5cLP
[19:17:47] <DaViruz> i recently emptied a ferguson tractor on oil. antique oil isn't all that great
[19:18:09] <andypugh> And that’s a tiny amount of antique oil.
[19:18:49] <Sync> wut. they still made tape punchers in 94
[19:18:51] <Sync> amazing
[19:19:26] <andypugh> It’s actually the right oil for my milling machine, but I am happy to pay £20 for 4 litres rather than £100 for 50cc.
[19:19:33] <DaViruz> my new cnc mill can store machine data on either punched tape or DSDD floppy
[19:19:42] <DaViruz> to be quite honest i trust punched tape a lot more
[19:20:07] <andypugh> DaViruz: I think I have some DSDD floppies, if yo need any.
[19:20:12] <Sync> I trust a floppy emulator more than a tape
[19:20:19] <greg> NMB says radial clerance in a normal bearing in smaller size is 5-12um
[19:20:25] <DaViruz> i managed to find one, which i backed up the machine data to
[19:20:30] <DaViruz> and then i made a image of it
[19:20:38] <DaViruz> so i'm probably fine
[19:20:38] <andypugh> Branded “Sheffield City Polytechnic” for extra retro-cred
[19:20:59] <DaViruz> Sync: i'm not sure how that'd work in this case
[19:21:03] <DaViruz> this isn't a pc floppy drive
[19:21:58] <andypugh> greg: You would generally choose a bearing with a RIC to suit the application. Typically that 5-12um would be expected to close up somewhat (possibly to slight preload) on installation.
[19:22:01] <yasnak> Ah yes, punch tape. Dad always gives me shit on my programs and reminds me he had to make programs right to begin with. He would send it out, get punch tape made and then they'd run the parts haha.
[19:22:24] <greg> if the bearing is preloaded you shouldn't be dealing with anything but runout
[19:22:28] <greg> RIC?
[19:22:37] <andypugh> Radial Internal Clearance
[19:22:45] <__rob> yea, just been googling
[19:22:57] <__rob> so that should be ok
[19:23:19] <greg> tight clearance is ~half that
[19:24:00] <__rob> there just cheap deep groove ball bearings at the moment
[19:24:29] <Sync> DaViruz: there are emulators that do most standards
[19:24:47] <DaViruz> i have no idea what standard this uses, if any
[19:24:57] <__rob> doesn't help tho that there is significant play in the current bearing socket
[19:25:07] <greg> loctite
[19:25:16] <DaViruz> besides, the machine has a v24 that can be used for machine data input/output
[19:25:18] <andypugh> Bearings come in various clearance grades. You need a bigger RIC for bearings with a tight interference fit on both races (for example motorcycle main bearings). Don’t mistake the clearance for a tolerance. The clearance is deliberate.
[19:25:38] <DaViruz> that's a way better option than mucking about with floppy emulators
[19:25:39] <greg> yes I know
[19:25:45] <DaViruz> ..v24 port
[19:26:15] <andypugh> greg: I am just lecturing to anyone who doesn’t know :-) Probably a sign it’s time I went to sleep.
[19:26:20] <andypugh> Night all
[19:27:03] <Sync> yeah if you have v24 all is well
[19:27:05] <greg> that's a common misconseption about bearings so it doesn't hurt
[19:28:46] <DaViruz> but inserting a floppy is a lot more convenient if the machine loses machine data (again)
[19:29:09] <greg> anyone tried making their own parkerizing solution?
[20:57:36] <zeeshan-mill> lslala
[20:59:52] <PetefromTn_> ?
[21:19:59] <zeeshan-mill> ??!
[21:20:01] <zeeshan-mill> machining :)
[21:22:25] <PetefromTn_> hell yah
[21:23:21] <PetefromTn_> http://imgur.com/5SthxcV tonights progress ;)
[21:23:39] <_methods> nice
[21:23:51] <_methods> i've been playin with xmas lights tonight
[21:23:54] <_methods> https://www.dropbox.com/s/0ncbdmkk50bruvu/2015-11-23%2019.25.55.mp4?dl=0
[21:24:42] <PetefromTn_> cool
[21:24:48] <PetefromTn_> what are you gonna do with em?
[21:25:01] <_methods> put em on the tree
[21:26:28] <_methods> you sell those mounts yourself or in a store or something?
[21:28:07] <PetefromTn_> I sell em on ebay and from my facebook page
[21:28:26] <PetefromTn_> and a lot are sold to folks I have competed with for years via word of mouth
[21:28:57] <_methods> you sell alot on ebay?
[21:29:27] <PetefromTn_> some... I seem to be selling more from my facebook page which I am good with because I have to pay extra for ebay
[21:30:07] <_methods> how many you sell a month?
[21:30:21] <PetefromTn_> depends on the month ;)
[21:30:34] <_methods> on avg?
[21:30:39] <_methods> 10-20?
[21:30:44] <_methods> 100
[21:30:46] <_methods> hehe
[21:30:54] <PetefromTn_> quite a few :D
[21:31:14] <_methods> i'm mainly curious about selling stuff on ebay
[21:31:19] <PetefromTn_> I have never sold more than a hundred a month
[21:31:26] <_methods> i've never tried it but was wondering just how effective it really is
[21:31:32] <PetefromTn_> I wish I did
[21:31:52] <_methods> yeah
[21:32:20] <PetefromTn_> I find a lot of the people who purchase from me seem to feel good about buying thru ebay due to the feedback and the idea that they have some recourse if I fail to deliver
[21:32:56] <PetefromTn_> at least that is the feeling I get and it is another resource
[21:32:59] <_methods> i need to start selling some stuff on ebay just to get my feet wet
[21:33:15] <PetefromTn_> I have found a surprising number of people somehow find me thru facebook tho
[21:33:54] <_methods> yeah i refuse to do facebook so that route is closed for me
[21:35:04] <PetefromTn_> why?
[21:35:20] <PetefromTn_> lemme guess.....it's GAY?
[21:35:24] <_methods> hahaha
[21:35:42] <_methods> you nailed it
[21:36:20] <PetefromTn_> not too many places you can have a business page lots of people can see for basically nothing
[21:36:45] <_methods> this is true
[21:37:14] <_methods> i don't do twitter either
[21:37:20] <_methods> i don't even get twitter at all
[21:37:38] <_methods> i made an account and was like wtf is this
[21:37:42] <_methods> it's like facebook
[21:37:47] <_methods> but more retarded
[21:37:48] <_methods> lol
[21:38:06] <PetefromTn_> I have a twitter account but I think I posted one time on it hehe
[21:38:19] <_methods> there's some other twitter thing i signed up for too but i don't remember what it's called
[21:38:25] <_methods> it was like the same thing as twitter
[21:38:48] <PetefromTn_> myspace?
[21:40:00] <_methods> hahah
[21:40:06] <_methods> no i skipped that one
[21:40:16] <_methods> wtf is this yikyak thing
[21:40:22] <_methods> i haven't even checked that one out
[21:40:50] <_methods> ah it was tumblr
[21:41:01] <PetefromTn_> I know Facebook is a big bloated big brother kind of bullshit site but I must admit it is nice to be able to keep in touch with not only my customer base but also my friends and family etc.
[21:41:52] <malcom2073_> Facebook is great for that. It's however terrible for most people who don't have a filter between their brain and mouth (or fingers)
[21:42:12] <malcom2073_> I use it for keeping up to date with family and friends that live across the world,
[21:43:18] <renesis> i didnt get a facebook until los angeles drum n bass promoters got lazy about updating their websites
[21:43:35] <malcom2073_> PetefromTn_: Those progress pics look good
[21:43:36] <renesis> and i dont think ive logged in since ive moved
[21:43:38] <malcom2073_> I wanna find something 3d to do on my mill
[21:43:45] <PetefromTn_> thanks man
[21:43:54] <_methods> yeah i had to get rid of facebook because the shit people would post was going to give me an aneurysm
[21:43:55] <malcom2073_> I've done all simple profile stuff so far
[21:44:16] <malcom2073_> Facebook is not very good for intolerant people
[21:44:18] <renesis> yeah i dont do social stuff, it took it years to suggest anyone i knew
[21:45:08] <_methods> facebook wasn't too bad at first but when peoples grand parents started getting on there it was time to go
[21:45:58] <PetefromTn_> malcom2073_ these are just simple profile parts too actually
[21:46:10] <malcom2073_> PetefromTn_: Yeah I was just looking closer and saw that heh
[21:46:22] <malcom2073_> Are the tapers 3d though?
[21:46:37] <PetefromTn_> what tapers?
[21:46:44] <malcom2073_> The beveled edges
[21:46:54] <PetefromTn_> oh no those are just champfers
[21:47:03] <PetefromTn_> cut with a 45 degree bit
[21:47:23] <malcom2073_> Ah nice
[21:48:10] <malcom2073_> Do you bandsaw those apart?
[21:48:28] <malcom2073_> Oh that is three blocks haha
[21:48:32] <malcom2073_> Looked like one at first
[21:57:43] <PetefromTn_> sorry had to change parts
[21:57:51] <PetefromTn_> yeah that is three different parts
[21:58:01] <PetefromTn_> not sure what you mean bandsaw
[22:12:48] <PetefromTn_> have any of you guys ever machined a Golf putter head?
[22:48:34] <PetefromTn_> guess not hehe
[23:08:01] <ssi> ror
