Back
[01:12:05] <Cromaglious_> back.. just had to run off and do an emergency plumbing job... $170 weeee
[01:12:33] <Cromaglious_> I hate the new leadless solder
[01:13:30] <Cromaglious_> propane and map gas don't like it.. you just have to use a plumbers acetylene torch
[01:17:00] <CaptHindsight> http://www.mmhtools.com/pic/big/206_0.jpg no crimping?
[01:19:21] <Cromaglious_> the band is solder on the inside... those are hard to get here
[01:20:10] <archivist> compression fittings
[01:20:52] <Cromaglious_> hehe pex
[01:21:42] <Cromaglious_> new construction here is usually pex..
[02:26:07] <Deejay> moin
[03:44:38] <LeelooMinai> Hmm, is it possible to "rigid tap" with linuxcnc and vfd controlled spindle?
[03:47:42] <archivist> yes it should be, you need to add an encoder to the spindle
[03:48:20] <archivist> a,b plus index encoder
[03:49:09] <archivist> but does your vfd slow down and reverse nicely, are you using a mesa card or parallel port
[03:49:15] <LeelooMinai> What does A, B mean? Rotation direction or something?
[03:49:37] <LeelooMinai> I have a Mesa card, yes.
[03:49:43] <archivist> quadrature outputs (to detect direction)
[03:49:53] <LeelooMinai> And index?
[03:50:09] <archivist> index is for start of movement
[03:50:47] <archivist> linuxcnc detects that then Z will track the encoder
[03:51:00] <LeelooMinai> Hmm, I have Chinese air cooled AC spindle - I may need to do something weird to get at the spindle from the top I think.
[03:51:20] <archivist> is it slow enough
[03:51:53] <LeelooMinai> No idea - 800watt, 220V, up to 20k RPM
[03:52:13] <LeelooMinai> And GS2 VFD
[03:52:23] <archivist> tapping is down at low speed with some torque
[03:53:58] <archivist> like ten turns in and then ten out
[03:54:00] <LeelooMinai> Right, I am not sure if AC spindles work well at required low speeds - I think I read that at some point they will overheat.
[03:56:49] <LeelooMinai> I guess I should research adding encoder to my spindle first. It can be useful anyways to have real RPM readout.
[03:57:25] <LeelooMinai> Not sure if I could somehow do it at the bottom - probably not easy this way.
[04:20:23] <LeelooMinai> Not sure how the air cooling works. I mean obviously there is a fan at the top, but is it directly driven by the spindle usually?
[04:20:40] * LeelooMinai ponders if 20k rpm fan is "normal"
[04:21:44] <LeelooMinai> Hmm, apparently fans for CPU are more in the area of 2k RPM, so I don't know.
[04:24:17] <archivist> not sure that is the right sort of spindle for tapping at all
[04:25:00] <LeelooMinai> Maybe at least small holes? I cannot tap bigger than 1/4 threads anyways.
[04:25:21] <LeelooMinai> If I could tap up to M6, it would be fine.
[04:27:49] <archivist> m6 is can be reasonable torque, 1-300 rpm
[04:28:11] <archivist> never use hand taps at speed
[04:30:49] <archivist> see machine taps, spiral point(push chips through), spiral (pull chips out backwards)
[04:31:37] <LeelooMinai> Right, if I ever manage to make it possible, I will get proper taps
[04:32:28] <LeelooMinai> Right now, I am kind of trying to judge if it can be done, and what I will need to research/add/modify
[04:34:15] <archivist> I made an encoder disk to fit on my spindle, not fitted the optos yet, mine is belt drive from the motor
[04:35:14] <LeelooMinai> Right, that's easier to do then - I don't even have anything rotating sticking out of the spindle at the back.
[04:49:28] <LeelooMinai> Hmm, after reading a bit more, it seems that running those spindles at less than 8k RPM is problematic, unless with vector drive, but even then only 4k or so min.
[05:26:41] <jthornton> morning
[06:09:44] <miss0r> Sometimes, I don't know why, my cnc takes forever to find home positions. *sigh*
[06:10:13] <XXCoder> why?
[06:10:17] <XXCoder> low ipm?
[06:10:24] <archivist> a slow day
[06:10:39] <archivist> that Monday morning feeling
[06:11:46] <XXCoder> monday morning the first week after holiday feeling
[06:14:28] <miss0r> I'm not sure why. It moves all the axis very close to homing position. This is where it usualy moves very slowly to the homing position. But sometimes (today included) it just hangs there for a long time. at some point it will move the last few mm
[06:14:32] <miss0r> and then be ready
[06:15:06] <miss0r> oh, before you get all interrested - this is a philips 432 controller, unfortunatly not linuxcnc
[06:15:29] <XXCoder> hm
[06:15:31] <archivist> rofl, upgrade to linuxcnc!
[06:15:35] <XXCoder> is it skipping steps?
[06:15:58] <miss0r> archivist I wish that I had the time. too much to integrate
[06:16:10] <miss0r> XXCoder its not moving at all. also - it uses servos
[06:16:26] <XXCoder> ah that'd detect non-motion
[06:16:30] <XXCoder> hm unno then
[06:16:34] <XXCoder> dunno
[06:17:19] <miss0r> archivist: short list: VFD, Electro gear, hydraulics for tool change, 3x servos, Spindle indexer, 3x linear readout.. and all sorts of digital inputs for error signals
[06:17:39] <miss0r> i'm probally missing something on this list :)
[06:17:50] <archivist> what fun
[06:18:14] <miss0r> Yeah, it realy realy sounds like a fun project, but I don't have the time to do it
[06:18:43] <miss0r> and I dont have the time for the machine to be down indefinetly while working out the perks - I use it from time to time
[06:21:52] <miss0r> the mill just moved a few hundreds of a mm, then went back to idle... *sigh*
[06:23:30] <miss0r> yay. its done homing... now work can begin
[06:25:59] <XXCoder> geez
[06:26:19] <miss0r> yeah. it realy has its off-days
[06:26:28] <miss0r> other days it fires right up. only takes 5 seconds homing
[06:28:11] <SpeedEvil> https://www.kickstarter.com/projects/1294137530/the-first-desktop-waterjet-cutter
[06:28:21] <SpeedEvil> wonder when they'll be $200 out of china.
[06:28:34] <SpeedEvil> Uses .3lb of garnet abrasive/minute of cutting
[06:28:42] <SpeedEvil> 'medium pressure' waterjet
[06:29:08] <miss0r> damn that is cool :D
[06:29:15] <SpeedEvil> Cuts 1/4" Al at 1IPM, 1/16" at 2.8
[06:29:29] <SpeedEvil> 1/8" glass at 12
[06:29:46] <SpeedEvil> I do wonder what the pressure is
[06:30:36] <XXCoder> desktop waterjet interesting
[06:31:15] <XXCoder> wonder what price on regular full size lol
[06:31:20] <XXCoder> $3500 on that kickstarter
[06:31:31] <SpeedEvil> Modulo the usual 'is it completely photoshopped' 'have they got a contract in chinese arbitrated by a chinese court with appropriate penalties for their factory' ...
[06:31:38] <SpeedEvil> 10-20 times that AIUI
[06:32:09] <miss0r> i'll take two
[06:32:44] <miss0r> no.. make that three :)
[06:42:12] <SpeedEvil> http://www.waterjets.org/index.php?option=com_content&task=view&id=50&Itemid=28 is a calculator you could run backwards with the stated 0.33lb/min of garnet
[06:42:34] <SpeedEvil> I do not have to hand a wine or windows install to run it
[06:49:14] <miss0r> you know the feeling where you are very far along on a project only to realize you are an idiot and have to start back at the drawing board? ARGH!
[07:03:44] <Filystyn> argh
[07:05:14] <XXCoder> https://www.youtube.com/watch?v=TzSOeNopLT4
[07:05:21] <XXCoder> miss0r: aw what happened
[07:05:48] <miss0r> I just realized what I was trying to do was impossible/huge impractical...
[07:06:23] <miss0r> borderline idiotic at best
[07:14:43] <XXCoder> ohh new clickspring
[07:14:47] <XXCoder> what was wrong with your idea
[07:16:47] <miss0r> I had to do a bore for a bearing, that I designed quite out of reach...
[07:19:53] <miss0r> I have revised the design to be comprised of more parts now
[07:21:11] <XXCoder> :)
[07:30:55] <XXCoder> wow finally see the clock complete
[08:52:41] <cnc_install123> hello everyone, I want to install linux cnc on this machine, it's 16.04, will a package work or do I have to build myself?
[08:57:01] <JT-Shop> you have to build and install a real time kernel and build linuxcnc for that kernel
[08:57:20] <cnc_install123> hm ok...
[08:57:34] <cradek> if you want to control machinery with it, JT-Shop's answer is right. if not, you can build linuxcnc in uspace mode.
[08:59:03] <cnc_install123> I'm afraid I'll have to do the thing JT said then :) are the instructions in the wiki?
[09:00:00] <archivist> or download the livecd and go from there, but older OS
[09:00:18] <cradek> that's the winning strategy if the main task for this computer is to control the machinery
[09:01:11] <cnc_install123> I like winning :D
[09:04:31] <cnc_install123> hm...
[09:04:37] <archivist> livecd will need updating once you are running
[09:05:02] <cnc_install123> I'd really like to "just" install it on this machine as it is...
[09:06:01] <cradek> it will pop up asking to install updates - let it do them
[09:07:58] <cnc_install123> cradek: so you mean I should reinstall the OS from the livecd?
[09:08:14] <cnc_install123> and then update?
[09:08:34] <cradek> that's the easiest way to get linuxcnc controlling machinery
[09:08:51] <archivist> yes, I usually start with a clean hard disk (any older disk as a slave)
[09:08:52] <cradek> whether that's the best thing to do in your situation I can't say
[09:09:22] <cnc_install123> :S I do like easy approaches... but I don't have a stick here etc...
[09:09:35] <JT-Shop> hmm linux mint 18 is out based on ubuntu 16
[09:10:23] <JT-Shop> this is how I installed linuxcnc on linux mint 17.3
http://gnipsel.com/files/linuxmint/mint17.3.txt
[09:11:28] <cnc_install123> that looks good I'll try that first...
[09:14:44] <JT-Shop> of course you would have to adjust it for whatever you have
[09:16:40] <cnc_install123> I don't think there is a release for xenial yet, but as far as I can see it installed the rtai without complaining...
[09:17:02] <cnc_install123> so I'll try rebooting and switching to it now...
[09:21:39] <cnc_install123> alright hopefully I'll be back soon. thanks for the help :)
[09:23:57] * JT-Shop has misplaced the hand truck...
[09:25:32] <linuxcncinstall1> hey, I'm back, looks good. For my record, what did I do just now? Use a different kernel?
[09:27:00] <linuxcncinstall1> ya. ok.
[09:27:07] <linuxcncinstall1> neat. Never did that before :D
[09:30:51] <pcw_home> There are some LinuxCNC incompatibilities with Mint 18/Ubuntu16.04
[09:30:53] <pcw_home> Not sure they are fixed yet
[09:31:34] <linuxcncinstall1> I guess I'll find out soon enough...
[09:37:24] <pcw_home> looks like the main showstopper was fixed in 2.7.7
[09:38:23] <linuxcncinstall1> that's good to hear!
[09:38:53] <JT-Shop> pcw_home: will the THCAD card work with a beaglebone 3.3v?
[09:39:32] <pcw_home> Not without a divider (it has 5V outputs)
[09:40:52] <The_Ball> After upgrading from Ubuntu 8 (very very old) to the new Debian based distro I'm getting axis following errors. But I'm not getting unexpected realtime delay warnings. Is there a config issue between 2.6 and 2.8 I should know about, or is this likely to be kernel/rt related?
[09:40:59] <The_Ball> I'm using a mesa card btw
[09:41:18] <The_Ball> And this is using stepping, so the following error doesn't make sense to me
[09:41:51] <The_Ball> I've increased fmin_error or what ever that option is called by a factor of 10 but it still happens now and then
[09:42:07] <skunkworks> is it printer port?
[09:42:25] <The_Ball> No, old PCI based Mesa card 5i25
[09:42:31] <JT-Shop> ok thanks
[09:42:48] <pcw_home> have you run a latency test?
[09:43:17] <The_Ball> So step generation is happening in the fpga and should feed back directly so I can't understand how a following error is possible
[09:43:34] <pcw_home> the stepgen is a feedback system
[09:43:42] <The_Ball> pcw_home, I did, but a while back when I first tried it, now that I'm keen to fix it I'll run it again more thoroughly
[09:43:53] <pcw_home> basically a velocity mode servo
[09:44:17] <The_Ball> pcw_home, yes, if there is a latency issue in the new kernel/rt on my platform that would explain it, but wouldn't I see "unexpected realtime delay" warnings?
[09:44:51] <pcw_home> make sure all axis stepgen accels are about 1.25x the machine accel limits
[09:45:19] <The_Ball> Ok, that's a good tip, I'll check that when I get to the barn
[09:46:57] <pcw_home> Probably what happened is this
[09:46:59] <pcw_home> 1. Your new OS has much worse latency than 8.04
[09:47:00] <pcw_home> 2. The stepgen driver does not deal well with poor latency unless the stepgen acceleration is bounded
[09:48:30] <pcw_home> we saw a lot of this when LinuxCNC moved from 8.04 to 10.04 (which also has worse latency in general than 8.04)
[09:50:05] <pcw_home> there are other fixes if needed (The stepgen can live with 500 usec or so latency now with the right HAL setup)
[09:51:07] <The_Ball> Ok, thanks a lot for the info, I'll run a long latency test to get my bearings
[09:53:53] <FloppyDisk525> What about the 2.7 INI changes from 2.6. Pet watchdog? Assume that should be 'off' for 2.8 as well.
[09:54:07] <FloppyDisk525> And, the parallel port thingy:
http://linuxcnc.org/docs/html/getting-started/updating-linuxcnc.html
[09:57:45] <pcw_home> yeah you need to comment out the pet watchdog addf and the loadrt probe_parport
[10:06:09] <linuxcncinstall1> JT-Shop: the debian/configure command says I have unmet dependencies :S, the packages that are missing can't be located or in the case of python-support don't have a release candidate, can I hope to succeed anyway?
[10:06:57] <MacGalempsy> awww yea. all is ready to go ge the EDM tomorrow
[10:07:17] <MacGalempsy> recovery of the dielectric should be fun
[10:09:50] <CaptHindsight> 5 gal pails and a pump
[10:11:01] <MacGalempsy> sounds like a good idea, I was thinking a couple of plastic 55gln drims
[10:11:09] <MacGalempsy> 2 so they can be moved
[10:12:09] <MacGalempsy> hoping that the weight is manageable with the equipment I have
[10:17:52] <linuxcncinstall1> :S
[10:23:19] <CaptHindsight> pails with lids may be carried by hand, the drums are ~500lbs full
[10:25:07] <MacGalempsy> good point
[10:25:09] <JT-Shop> I'm guessing not
[10:25:38] <JT-Shop> MacGalempsy: a wire or plunge?
[10:25:41] <MacGalempsy> you think regular plastic homedepot buckes would be good?
[10:25:49] <MacGalempsy> JT-Shop: plunge
[10:26:07] <MacGalempsy> they had wire, too, but those were too big for my garage
[10:26:12] <linuxcncinstall1> yeeeaaah no it's not working
[10:26:20] <CaptHindsight> MacGalempsy: yes and they have lids that seal
[10:26:37] <MacGalempsy> ok, I think that will be better.
[10:27:24] <linuxcncinstall1> ah well... at least this machine can boot from a stick so I don't have to go through the trouble of buying and burning a cd...
[10:27:27] <MacGalempsy> JT-Shop: the machine is a Hansvedt 501 head with a 201 pulse psu
[10:27:29] <CaptHindsight> 20gal plastic drums are easily moved with a hand truck
[10:28:01] <MacGalempsy> one of the manuals states 45gln in the reservoir
[10:28:18] <MacGalempsy> well, a different model, but similar age and size
[10:28:47] <CaptHindsight> not sure where you would source those locally unless a car wash saves them
[10:29:39] <MacGalempsy> I can get those plastic 55ln drums cheap and easy, maybe just get 2 and fill them 1/2 way
[10:30:41] <MacGalempsy> the fluid will be the easy part. im trying to determine if the drawworks can be seperated from the cabinet.
[10:31:10] <MacGalempsy> https://www.flickr.com/photos/58181938@N03/29316740440/in/dateposted-public/
[10:31:31] <MacGalempsy> i think that it will seperate some
[10:31:56] <FloppyDisk525> That guy (edm) is gorgeous...
[10:32:11] <MacGalempsy> thanks
[10:32:41] <MacGalempsy> its quite shocking :)
[10:34:03] <MacGalempsy> the interesting part will be getting it into position. if you scroll through those photos, it is going where the computer workstation is currently positioned
[10:34:22] <CaptHindsight> MacGalempsy: are you going to add some fire suppression to your garage?
[10:34:23] <MacGalempsy> today will be fun moving stuff around more
[10:34:55] <MacGalempsy> i'll have to figure that part out
[10:35:05] <MacGalempsy> maybe a couple of big extinguishers
[10:35:44] <MacGalempsy> i'll have to put the 911 in the driveway while EDMing
[10:39:02] <linuxcncinstall1> ugh...
[10:39:18] <linuxcncinstall1> 1.5 hours download? this is why other people distribute just program :P
[10:39:25] <linuxcncinstall1> *programs
[10:39:53] <linuxcncinstall1> thank you all for your help and for being here! I'll probably see you soon. :)
[10:40:18] <cradek> ...
[10:41:28] <gregcnc> how much power does that EDM require?
[10:46:51] <CaptHindsight> less than a welder
[10:48:05] <gregcnc> not a big deal then
[10:51:20] <MacGalempsy> lagged out
[11:03:25] <CaptHindsight> http://www.ebay.com/itm/Konmison-Linear-Stage-Actuator-Table-100mm-Travel-Length-Linear-Moudle-for-DIY-C/282052916128 must be good ...
[11:03:38] <CaptHindsight> Stash gives it the thumbs up
http://i.ebayimg.com/images/g/bjMAAOSw6btXS8bi/s-l500.jpg
[11:03:53] <gregcnc> lol
[11:08:53] <MacGalempsy> lol
[11:08:57] <MacGalempsy> that is nice
[11:09:07] <MacGalempsy> what you going to make with 100mm?
[11:09:33] <gregcnc> that is more than some china routers Z
[11:11:02] <gregcnc> i always thought THK KR were interesting www.ebay.com/itm/191937524166 never tried one
[11:11:26] <MacGalempsy> those look a lot better than that chinese crap
[11:13:45] <CaptHindsight> the THK uses profile vs cam bearings
[11:14:11] <CaptHindsight> 2 thumbs up
[11:15:44] <gregcnc> the block has recirculating ball bearings and rides ground rails on either side. I'm sure they are expensive new
[11:17:29] <CaptHindsight> they start around ~$1k
[11:19:36] <CaptHindsight> cam bearings are fine, you'd use them over profile bearings in a high speed design...
[11:20:01] <CaptHindsight> but not how the maker stuff does it with them riding on the t-slot
[11:20:45] <CaptHindsight> you'd still use a ground rail or rod
[11:24:34] <CaptHindsight> http://www.bwc.com/
[11:25:33] <MacGalempsy> gregcnc: you looking at building a new machine?
[11:25:34] <CaptHindsight> likely where that openbuilds got their inspiration from to "invent" extrusions and cam bearings
[11:26:26] <CaptHindsight> http://www.bwc.com/products/manual-linear-guide-systems/quicktrakr.html
[11:27:27] <CaptHindsight> http://www.bwc.com/madewell.html
[11:27:28] <archivist> I would say the idea has been around since sliding doord
[11:28:14] <gregcnc> no space for new machines. i have rails and screws for a ~2x6" router.
[11:28:39] <gregcnc> well maybe feet not inches
[11:28:52] <CaptHindsight> archivist: maker heresy!
[11:29:24] <archivist> hell even steam engine valve slides
[11:31:59] <archivist> it is a good laugh to read patent applications that get listed in various places, see how many are repeats
[11:31:59] <FloppyDisk525> gregcnc: those thk slides are nice, fairly rigid.
[11:32:37] <FloppyDisk525> funny note, Kollmorgen slides use Hiwin square rails (profile is what c-hindsight calls them)
[11:32:53] <FloppyDisk525> Which is odd because Thomson and kollmorgen are danaher and across the street from each other.
[11:33:08] <FloppyDisk525> Heard they don't play that well together, must be the case.
[11:33:25] <gregcnc> well they were all bought up
[11:33:32] <archivist> hiwin probably a lot cheaper
[11:33:35] <CaptHindsight> http://www.thomsonlinear.com/website/com/eng/products/linear_guides/profilerail.php
[11:34:44] <CaptHindsight> http://www.thomsonlinear.com/micro/guidance_eng/Round-vs-Square.htm
[11:37:27] <CaptHindsight> Hiwin assembles their lead and ballscrew positioners near me in Elgin, IL
[11:38:06] <CaptHindsight> the linear servo's are all done in Taiwan
[11:50:05] <MacGalempsy> this looks interesting.
http://www.firetrace.com/applications/industrial-fire-suppression/edm-machines/
[11:51:13] <MacGalempsy> from what it says, one only has to worry if the fluid level gets too low
[12:07:33] <nubcake_> Crom: the -v2 from yesterday reads "FD-A-V2" not very helpful i guess
[12:25:03] <archivist> hmm time to batten down the hatches, it is a bit dark over grannies
[12:29:52] <jdh> en englese?
[12:31:02] <archivist> thunderstorm over the horizon
[12:31:47] <archivist> Highest September temperature since 1911 as 34.4C recorded
[12:35:33] <JT-Shop> step 1 get that beast of a fugi out of the shop... done
[12:35:51] <JT-Shop> step 2 get that beast of a fugi into the new building out of my way...
[12:48:16] <FloppyDisk525> fugi?
[12:52:47] <JT-Shop> was an optical comparator, still has a good XY table with DRO
[12:52:55] <JT-Shop> just don't know what to do with it lol
[12:53:27] <archivist> give it meeeee

[12:53:47] <JT-Shop> come and get it
[12:54:06] <archivist> got my own homebrew one though now
[12:54:28] <JT-Shop> light didn't work so I just took all that mess off of it
[12:54:49] <archivist> replace with an LED, make it work
[12:55:04] <JT-Shop> way too late for that lol
[12:56:03] <archivist> add a camera, lights and linuxcnc, optical cmm
[12:57:58] <archivist> mine started as a toolmakers microscope
http://www.collection.archivist.info/searchv13.php?searchstr=citizen
[12:58:51] <archivist> the lenses were damaged(coating fallen off)
[12:59:40] <JT-Shop> I sorta considered putting a Z on it with a probe...
[13:00:12] <archivist> keep it dry, save the bits :)
[13:00:45] <archivist> I put jobs/ideas to one side for a "few" years :)
[13:01:35] <JT-Shop> I saved most of the components like mirrors and power supplies and the DRO is still hooked up and working
[13:02:49] <JT-Shop> next project on the list is to build a proper powder coat oven
[13:02:58] <archivist> with a camera you can use focus to measure height
[13:03:55] <FloppyDisk525> That fuji has a nice base. I saw some guys take to ovens and stack them so they could powder coat motorcycle stuffs...
[13:04:05] <FloppyDisk525> to/two... eecks.. getting old
[13:04:48] <FloppyDisk525> Oooh, thumbwheels on the fuji - nice...
[13:06:48] <CaptHindsight> good for low or non-contact work, inspection, inkjet, laser etc
[13:18:21] <IchGucksLive> Hi
[13:18:25] <IchGucksLive> Im Back
[13:18:40] <IchGucksLive> after nearly 3 years in the German outback
[13:19:04] <IchGucksLive> Lot has changed
[13:19:12] <IchGucksLive> no mote 10.04
[13:19:51] <IchGucksLive> i need to Thank all who helped my folks that have been running the shop since
[13:20:13] <IchGucksLive> starting to regain live
[13:20:31] <IchGucksLive> by uploading 100+ liuxcnc advice videos
[13:21:32] <IchGucksLive> lots will now my MAYBE for those not im Lothar from Germany
[13:22:57] <CaptHindsight> hello!
[13:23:10] <CaptHindsight> How did you like being a park ranger?
[13:24:10] <CaptHindsight> IchGucksLive: ^^
[13:25:16] <CaptHindsight> while you were away tjtr33 retired to Thailand
[13:26:56] <IchGucksLive> im also but im still alive
[13:27:11] <MacGalempsy> JT-Shop: how big of an oven are you looking for?
[13:27:12] <Tom_itx> get lonely?
[13:27:30] <IchGucksLive> CaptHindsight: the expirience of a livetime
[13:28:11] <MacGalempsy> this auction in NJ has 2 Boy22 Ton injection machines.
[13:28:15] <IchGucksLive> ok im off for today
[13:28:32] <MacGalempsy> the footprint is nice and small
[13:28:36] <IchGucksLive> 7vids uploaded
[13:29:06] <JT-Shop> 3x3x4 tall
[13:29:28] <JT-Shop> or something like that
[13:29:42] <MacGalempsy> that seems like a good size for most parts
[13:30:10] <CaptHindsight> MacGalempsy: desktop machine?
[13:31:02] <MacGalempsy> my buddy works at a steel target manufacturing shop on the missouri/ark border and they now powder coat the targets that they cut out with a giant laser
[13:31:10] <MacGalempsy> CaptHindsight: no they are about the size of a ford ranger
[13:31:15] <MacGalempsy> maybe a little smaller.
[13:31:51] <MacGalempsy> the thing with the desktop designs that I see on EvilBay are like $7k and use pneumatic actuators
[13:32:35] <MacGalempsy> seems like looking around a little would allow one to find a used one that can do automated ops
[13:33:10] <MacGalempsy> CaptHindsight: on page 4 there are a couple examples
https://www.thebranfordgroup.com/dnn3/Auctions/SalesDetail/tabid/218/ct/gallery/SaleID/812/Default.aspx
[13:34:23] <CaptHindsight> MacGalempsy: I come across deals on them all the time
[13:35:03] <MacGalempsy> interesting. what does one like that usually go for?
[13:35:04] <CaptHindsight> when I heard small footprint I thought of those desk top models
[13:35:48] <MacGalempsy> the desktop just dont seem like they could put out the quanity that I'm looking for
[13:35:58] <CaptHindsight> all over the place, I was offered a 150 ton machine for $10k in great shape
[13:36:03] <MacGalempsy> not enough clamping force for more than one knob at a time
[13:36:37] <MacGalempsy> saw a lot of those this weekend. but I want something that will fit in my garage, and leave enough room for the wife to part inside.
[13:36:55] <MacGalempsy> that is why the 22 or 30 ton machines seem like the best bet
[13:39:20] <CaptHindsight> http://www.ebay.com/itm/50-Ton-Van-Dorn-Trubor-Plastic-Injection-Molding-Machine-Press-with-Maunals-/142108547777
[13:40:15] <MacGalempsy> This one is like 3 miles from the house injection machine
[13:40:22] <MacGalempsy> http://www.ebay.com/itm/NISSEI-1990-INJECTION-MOLDING-MACHINE-PS-E-TYPE-26-MM-SCREW-DIA-/191964883881?hash=item2cb1ffaba9:g:mr0AAOSwNSxVZ0-2
[13:40:33] <CaptHindsight> saw that
[13:40:39] <CaptHindsight> http://www.ebay.com/itm/VAN-DORN-INJECTION-MOLDING-MACHINE-350-TON-35-OZ-SHOT-SIZE-/172329073678
[13:40:50] <CaptHindsight> 350 ton, 35oz
[13:40:50] <MacGalempsy> I sent them a msg so I can go look at it
[13:41:29] <CaptHindsight> MacGalempsy: do you have the power?
[13:41:55] <MacGalempsy> look at the specs
[13:42:05] <CaptHindsight> HEATER - 1208 V, 12 A :) typo
[13:42:08] <MacGalempsy> its not that big. a 350 tone machine is huge
[13:42:43] <MacGalempsy> I would love to see a mold design that requires 350ton with a 450x450mm platen size
[13:43:41] <MacGalempsy> lol. was looking at that 1208V and was thinking that is some high voltage!
[13:44:49] <MacGalempsy> imagine this image without the computer in place. and the EDM in the corner and the plastic injection machine along the wall with the window
[13:45:02] <MacGalempsy> that is why I am interested in the smallest machine
[13:46:19] <MacGalempsy> this is the end product
http://www.ebay.com/itm/TOYOTA-LAND-CRUISER-FAN-SWITCH-KNOB-FJ40-FJ45-FJ55-FJ-40-45-55-landcruiser-/351777087323?hash=item51e78c5f5b:g:b-MAAOSwMmBVz4v8&vxp=mtr
[13:47:16] <CaptHindsight> I can SLA those
[13:47:45] <MacGalempsy> probably, but not as fast as injection molding
[13:47:53] <MacGalempsy> can you do 2 color?
[13:48:03] <CaptHindsight> thats actually a good application for SLA printing
[13:48:20] <CaptHindsight> extinct auto parts
[13:48:50] <CaptHindsight> if you have a sample or even a broken sample
[13:49:41] <MacGalempsy> the extint landcruiser market is what I will focus on
[13:49:56] <CaptHindsight> MacGalempsy: the comparison between injection molding and SLA comes down to how many and how fast
[13:50:13] <CaptHindsight> while the molds are being made the SLA is making parts
[13:50:16] <JT-Shop> $54 for a knob!
[13:50:21] <MacGalempsy> lol
[13:50:47] <MacGalempsy> my goal is to do a whole set of interior knobbs that wholesale around $150
[13:50:50] <CaptHindsight> so the crossover tends to be in the k's of parts
[13:50:56] <MacGalempsy> well, maybe 100
[13:51:24] <MacGalempsy> the interior has over 25 plastic parts, none of which are easily available
[13:52:05] <CaptHindsight> the purist will only want genuine Toyota
[13:52:45] <CaptHindsight> but Year One-like repros will be popular
[13:53:15] <MacGalempsy> they already are
[13:53:48] <MacGalempsy> there are certain pieces that are unobtainiium. the plastic dome lite cover took me 2 years to find
[13:54:10] <MacGalempsy> the 4wd light switch, 3 years
[13:54:54] <MacGalempsy> so, at least there will be something available to those who are restoring their rides
[13:55:07] <MacGalempsy> and it makes all landcruiser purchases a tax writeoff!
[14:36:03] <Cromaglious_> of a landcruiser... thought I read land rover
[14:36:38] <Cromaglious_> I really want a late '60s aluminum body long wb defender
[14:36:59] <Cromaglious_> with the perkins diesel
[14:37:27] <CaptHindsight> no rust so they tend to sell for >$10K practically gutted
[14:37:58] <Cromaglious_> yep... but they still corrode
[14:38:31] <CaptHindsight> the Ford pickup went to aluminum bodies, I wonder what they kept steel so they will rust
[14:39:08] <CaptHindsight> anodize the whole body
[14:39:09] <Cromaglious_> that's what we had in Malaysia... now you can have electrollytic action!
[14:39:27] <MacGalempsy> powder coat that baby
[14:39:37] <CaptHindsight> sounds like Brawndo
[14:39:48] <Cromaglious_> with AL... better Anodizing
[14:41:19] <CaptHindsight> but it doesn't flex well
[14:41:33] <MacGalempsy> rhinoline
[14:41:38] <CaptHindsight> titanium body
[14:41:44] <MacGalempsy> yeah
[14:41:48] <MacGalempsy> now youre talking
[14:41:57] <MacGalempsy> with teflon impregnation
[14:44:08] <Cromaglious_> I want a cast bronze body with a titanium frame, turbo diesel
[15:01:44] <Cromaglious_> anyone running Time Warner Cable internet?
[15:02:06] <JT-Shop> no cable out in the woods
[15:02:57] <Cromaglious_> out in the woods.. you should be running a flat panel ptp link back to where there is internet
[15:04:01] <Cromaglious_> got a bubby in iowa he's running a ptp internet service out in the middle of nowhere... his average link distance is over 2km
[15:04:43] <Cromaglious_> pretty stable business he has 5 schools and 2 hospitals
[15:09:04] <FinboySlick> Our longest link is 37km at 77Mbps.
[15:10:36] <FinboySlick> But if you don't want to break the bank, Cambium ePMP with a parabolic isn't too expensive and will give decent performance.
[15:12:37] <Cromaglious_> ugh.. either table is covered in AL dust and chips (very tiny chips)
[15:16:21] <MacGalempsy> JT-Shop: you have dialup modem?
[15:18:14] <JT-Shop> sat
[15:25:23] <JT-Shop> wildblew
[15:25:39] <MacGalempsy> does anyone use the probe function to "scan" an object?
[15:30:01] <JT-Shop> I'm sure some do
[15:30:47] <JT-Shop> someone please come over and clean out the chnc coolant tank
[16:03:09] <CaptHindsight> FinboySlick: my neighbors complained about mine
http://img.geocaching.com/cache/log/display/69ce9f51-48b5-4dab-8ad5-9fe044bcd296.jpg :)
[16:04:04] <FinboySlick> Hehe, back when I was at Teleglobe, we had a 100' diameter one.
[16:04:29] <CaptHindsight> the area around JT's is too hilly for p2p
[16:04:56] <CaptHindsight> they would have to cut down trees or use towers
[16:05:29] <FinboySlick> We need microwaves that are affected by gravity. That way we could do ballistic p2p links.
[16:06:00] <Cromaglious_> heh
[16:06:13] <CaptHindsight> or send up a cloud full of metal ribbons
[16:06:38] <djdelorie> again?
[16:07:31] <FinboySlick> A very fast USB-stick machine gun. You'd need great aerodynamics so they line up with the row of ports at the target though.
[16:07:40] <CaptHindsight> balloons at 200ft with repeaters on gimbals
[16:08:19] <CaptHindsight> yeah, ask someone with a high speed connection to download everything you want for the next day, ship flash drive
[16:08:46] <CaptHindsight> FinboySlick: USB funnels
[16:09:20] <FinboySlick> "Never underestimate the bandwidth of a station wagon filled with microSD.
[16:10:02] <CaptHindsight> ping times 86,400,000ms
[16:10:02] <FinboySlick> Kinda sucks for Counterstrike though.
[16:10:51] <FinboySlick> http://images.delcampe.com/img_large/auction/000/305/476/939_001.jpg
[16:11:02] <FinboySlick> That was our 100' dish.
[16:11:13] <XXCoder> lol your dish small
[16:11:26] <CaptHindsight> I used to work with smaller ones back in the 80's, 3-10m
[16:11:45] <FinboySlick> The rectangular building on the left contains a jet turbine to power the generator.
[16:11:56] <XXCoder> http://www.space.com/images/i/000/056/658/original/china-fast-radio-telescope.jpg that's mine
[16:12:12] <XXCoder> you can see my house there, blue roof
[16:12:26] <CaptHindsight> FinboySlick: were you uplinking to the EU?
[16:13:00] <FinboySlick> CaptHindsight: That was aimed at satellites. Mostly TV stuff.
[16:13:23] <CaptHindsight> to the east?
[16:13:53] <FinboySlick> How do you compute 'east' from the picture?
[16:14:21] <CaptHindsight> sun is on the right
[16:14:54] <CaptHindsight> and it the aim looks low
[16:15:04] <CaptHindsight> how far north was this?
[16:15:13] <FinboySlick> It's fairly far north. It's pointing south.
[16:15:21] <FinboySlick> And that was in the fall too.
[16:15:25] <FinboySlick> So low sun.
[16:15:39] <CaptHindsight> heh, south for me would have been ~48 deg
[16:16:51] <FinboySlick> http://photos.wikimapia.org/p/00/00/47/18/72_big.jpg
[16:16:51] <gregcnc> too bad you can't install usb drivers on win98...from usb I wonder if I have a working floppy drive and disks
[16:17:18] <Cromaglious_> win98 x2 you could
[16:17:25] <FinboySlick> win98? On real hardware?
[16:17:25] <XXCoder> gregcnc: think someone made drivers for win98
[16:17:28] <XXCoder> unoffical but works
[16:17:32] <CaptHindsight> p2p mesh networks have been poohpooed by big nosy here
[16:18:02] <FinboySlick> gregcnc: null modem serial port with hyperterminal.
[16:18:17] <gregcnc> I've done it before but had floppies back then, probably here under....something
[16:18:17] <Cromaglious_> usb came out right when win98 came out and the win98 second edition had them built in
[16:18:29] <gregcnc> well this se didn't like it
[16:18:36] <Cromaglious_> hmm
[16:18:53] <CaptHindsight> FinboySlick: dish farm
[16:19:08] <gregcnc> i bet if I have the disks, the drivers are still on them
[16:19:20] <FinboySlick> When I went there, they were doing maintenance on the largest one. It was aimed straight up and looked like a giant cereal bowl.
[16:19:59] <FinboySlick> The base has microwave detectors and huge waveguides. There's an alarm and we were warned: If these go off, you have 30 seconds to get out or you cook.
[16:20:24] <XXCoder> greg maybe
https://www.raymond.cc/blog/how-to-install-usb-mass-storage-device-on-windows-98/
[16:20:42] <CaptHindsight> did anyone used to get their linux on floppies since dialup would take too long?
[16:20:54] <cradek> I totally did
[16:21:09] <XXCoder> heh bought book with linux on cd
[16:21:09] <FinboySlick> I remember doing a debian net install over 56k modem once.
[16:21:10] <cradek> I went to campus with boxes of floppies and downloaded slackware
[16:21:13] <FinboySlick> Took 20 hours.
[16:21:13] <XXCoder> it sucked.
[16:21:25] <cradek> boxes and boxes
[16:21:50] <cradek> I could keep up with about four of those PS/2s writing floppies
[16:22:04] <CaptHindsight> I remember going to Microcenter to buy Suse on 1 CD
[16:22:23] <XXCoder> red hat if I recall.
[16:22:27] <XXCoder> 1.x something
[16:22:56] <FinboySlick> PS2, the life and death of the microchannel bus ;)
[16:24:32] * djdelorie still remembers swapping 360k floppies on his S/100 bus computer...
[16:25:08] <XXCoder> djdelorie: still have 7" inch drives? NASA will buy tons of money for those heh
[16:25:14] <XXCoder> err 8"
[16:25:21] <djdelorie> and spooling data out to tape, both casette and 1/4"
[16:25:38] <djdelorie> no, I was just after that, we had the first of the 5.25" ones. I had a friend with 8" drives though
[16:25:50] <Deejay> gn8
[16:26:22] <XXCoder> heh yeah first ones i used was smaller version - 3 1/4?
[16:26:32] <djdelorie> 3.5" is the small size
[16:26:59] <CaptHindsight> https://en.wikipedia.org/wiki/Floppy_disk#Sizes
[16:27:02] <XXCoder> though I did use 5.24 disks and my comoputer had em but it wasnt very common, windows 3.11 and dos was virtually only time I used those
[16:27:37] <djdelorie> stacks and stacks of floppies for djgpp...
[16:29:51] <CaptHindsight> and then the first external hard rives
[16:30:11] <CaptHindsight> so you would have to swap floppies to run some application or load the OS
[16:30:32] <CaptHindsight> no longer
[16:31:19] <Crom> I had planet connect newsgroupsand got me first distri that way.. then went and bought a walnut creek cdrom slackware
[16:31:42] <CaptHindsight> line 2045 of 8566 in your G-code, "insert next floppy"
[16:32:36] <Crom> been looking at one of thosefloppy emulatorsusing sd cards
[16:32:41] <FinboySlick> OK, off I go.
[16:34:04] <Crom> o the raid case I got... the back plane is dead
[16:34:43] <FloppyDisk525> what about the zip drive, too expensive for me, but lot's of people had them.
[16:35:37] <CaptHindsight> so no ZipDisk525? :)
[16:35:45] <Crom> zip drives sucked... I had a bernoulli box for awhile... same problem as the zip drives or jazz drives
[16:46:21] <Crom> sheeshz.. bought 4 usb to esata adapters can only find one
[16:47:40] <Demure_> Hello! Finally cut my first few completely succesful parts on the lathe. :)
http://imgur.com/a/R7ml1
[16:48:09] <gregcnc> looks good flashflight parts?
[16:48:15] <Demure_> Nope, camera parts!
[16:48:49] <Demure_> Even parting is now leaving a nice surface finish.
[16:49:01] <Crom> nice!
[16:49:08] <MacGalempsy> looks like a nice finish
[16:49:39] <Demure_> I'm very pleased, better than I was expecting. Thanks everyone who helped me out with my questions on here! ;)
[16:50:02] <SpeedEvil> :)
[17:03:52] <Demure_> ...So anyway, small question. I'm running an 80v power supply with Leadshine AM882 drivers, which I do not plan on upgrading. The motors however are 2a NM23 motors I had around that do the job well, but not fast enough. What specs should I look for to get a good speed increase?
[17:04:11] <Demure_> I'd like to do some multi-start threads and I can barely do a 2 start thread
[17:14:06] <Crom> going to bigger diameter nema steppers will help nema34 and bigger. 80v is a good voltage for steppers.. just go bigger on the motors
[17:14:25] <JT-Shop> bigger is slower usually
[17:14:46] <JT-Shop> take a look at the rpm charts at automationdirect.com
[17:15:15] <JT-Shop> Demure_: are they single, double or triple stack motors?
[17:15:17] <Crom> at 80v you can get around a lot of that
[17:15:57] <Demure_> JT-Shop: I'm unfamiliar with that specific, what is a stacked motor? I'm assuming single.
[17:16:03] <JT-Shop> Demure_: what rpm are the steppers turning now?
[17:16:21] <Demure_> Let me calculate that
[17:16:25] <Demure_> These are what I currently have:
[17:16:27] <Demure_> catalog.orientalmotor.com/item/stepping-motors/pk-series-stepping-motors/pk268-02a?jumpMenu=%23
[17:16:58] <Crom> http://catalog.orientalmotor.com/item/stepping-motors/pk-series-stepping-motors/pk268-02a?jumpMenu=%23
[17:20:33] <Demure_> The math is escaping me. It's a 2.5mm pitch ball-screw with a 2.5 reduction from the motor (40 tooth on the ballscrew, 16 tooth on the motor). I'm getting rapids of max around 1200mm/min
[17:20:53] <Crom> looks like 250rpm top speed with torque above 2ozin and
[17:21:45] <JT-Shop> https://www.automationdirect.com/static/specs/surestepmotors.pdf
[17:23:04] <Crom> http://catalog.orientalmotor.com/browser?&plpver=11&prodid=3001048&itemid=62144&assetid=26318
[17:23:13] <Demure_> Would the math be correct in being 1200RPM or am I being silly? 2.5mm movement for each rotation, so 1200/2.5=480 rotations a minute of the ballscrew, times the 2.5 geardown = 1200?
[17:23:49] <Demure_> The unipolar vs bipolar thing always confused me as the Leadshine manual never seems to bring it up
[17:24:05] <Demure_> It only talks about half-coil or full-coil wiring
[17:24:25] <Crom> bipolar is 4wire uni is 6 or 8
[17:24:27] <Demure_> I'm fine losing out on the torque as I can make very light threading passes
[17:24:47] <Demure_> I have 6 wires, but I only wired 4 of them in 'full-coil'.
[17:25:20] <Demure_> If I have it wired bipolar, than the inductance is 14.4 per phase, which is quite high, no?
[17:25:28] <JT-Shop> http://wiki.linuxcnc.org/cgi-bin/wiki.pl?Stepper_Formulas
[17:25:37] <JT-Shop> http://wiki.linuxcnc.org/cgi-bin/wiki.pl?Stepper_Motor_Speed_Limitations
[17:25:51] <JT-Shop> that's above my pay scale :)
[17:26:00] <Crom> ditto
[17:26:44] <Demure_> No worries, thanks for the help. :)
[17:26:55] <FloppyDisk525> I forget the reason, but you can't take a unipolar 6-leaded and make it bi-polar.
[17:27:04] <JT-Shop> lots of info on the wiki links
[17:27:14] <FloppyDisk525> You can take an 8 leaded and wire it either uni-polar or bi-polar.
[17:27:17] * JT-Shop has to get back to work
[17:27:21] <Demure_> Goodluck!
[17:27:22] <Crom> lower inductance is better
[17:27:34] <FloppyDisk525> I think the center taps of the unipolar are 'tied' together, but I forget...
[17:27:54] <Demure_> FloppyDisk525, Thanks for the info. I thought I had that option as the specs of the motor lists specs in both unipolar and bipolar
[17:28:00] <FloppyDisk525> Oh, the leadshine would definitely be bipolar.
[17:28:18] <FloppyDisk525> Unipolar where like the first stepper drivers made and bipolar has better performance, etc.
[17:28:28] <Demure_> Ah I see, that's good to know
[17:28:37] <Demure_> Than I also know my motors have a very high inductance
[17:28:50] <FloppyDisk525> As I'm writing, I guess you 'can' take the 1/2 the winding or something like that for unipolar motors...
[17:28:55] <FloppyDisk525> Oh - the inductance.
[17:29:12] <FloppyDisk525> Older motors I think had higher inductance, think of a hammer hitting a nail.
[17:29:22] <FloppyDisk525> Larger inducatnce, larger nail.
[17:29:36] <FloppyDisk525> In the old days, some stepper drives could only drive certain motors or they'd burn up.
[17:29:40] <JT-Shop> Demure_: what is your max speed now?
[17:29:47] <Demure_> I see.
[17:29:56] <Cromaglious_> higher inductance the motor has, the slower it reacts to the step pulse.
[17:29:57] <Demure_> JT-Shop: I'm getting rapids of 1200mm/min
[17:30:12] <Demure_> Which if I'm correct is actually equal to the RPM, but my math is super dodgy on this.
[17:30:15] <FloppyDisk525> but newer stepper drives can either be set or maybe adjust, not sure about leadshine. I'm talking more like parker or kollmorgen.
[17:30:32] <Cromaglious_> since the pulse magnetic field builds slower
[17:30:34] <Demure_> I have a fair few adjustments I can make in the drives
[17:30:37] <Cromaglious_> which limits RPM or steps per time period
[17:30:38] <JT-Shop> <50 inches/min so yea that is slow
[17:30:40] <FloppyDisk525> Anyway, watch your motors and drives for heat
[17:30:42] <Demure_> They're digital onces
[17:30:45] <FloppyDisk525> If you can touch them, you're good to go.
[17:30:55] <Demure_> Right now they're building up to be warm at most, never too warm to touch
[17:31:03] <Demure_> The motors get warm, the drives I have never felt to be even close to warm.
[17:31:05] <JT-Shop> you have a gear or belt from the stepper to the ballscrew?
[17:31:07] <FloppyDisk525> Even if you can't touch them, they still might be okay. Steppers can run really hot.
[17:31:10] <Demure_> BElt.
[17:31:16] <JT-Shop> steppers my nature are hot
[17:31:23] <FloppyDisk525> Yup...^
[17:31:24] <JT-Shop> hotter when holding still
[17:31:26] <Demure_> So I've heard, so I'm not too worried about that.
[17:31:48] <Demure_> The drives have an idle mode for not moving and lowers the output to keep them cooler
[17:31:54] <JT-Shop> what is the gear ratio
[17:31:58] <Demure_> Seems to do the trick, they mostly get very hot making very slow movements
[17:32:15] <Demure_> 40 teeth on the ballscrew, 16 on the motor, so a 2.5x reduction
[17:32:48] <JT-Shop> so one revolution of the ball screw goes 2.5mm
[17:33:03] <Demure_> Yup
[17:33:27] <Demure_> Thus my thinking of 1200/2.5 of the ballscrew = 480 rotations a minute on the ballscrew end
[17:33:41] <Demure_> Which means the motor is going 2.5 times as fast
[17:33:49] <JT-Shop> yep
[17:33:51] <Demure_> 2.5*48- = back at the 1200, but now as RPM
[17:33:52] <Cromaglious_> 2.5 faster
[17:34:09] <Demure_> So the steppers are going at 1200 RPM max
[17:34:12] <JT-Shop> yep your at max speed, try a different gear ratio
[17:34:21] <Demure_> Is this a reasonable amount for a stepper?
[17:34:48] <JT-Shop> you might get 100 more rpm maybe, a nice large nema 23 triple stack can go 1500 or better
[17:35:25] <JT-Shop> my plasma goes 15,240mm/min
[17:35:26] <Demure_> That's not as much of an increase as I'm trying to find, though, so perhaps new steppers is not ideal.
[17:35:30] <Demure_> Yikes
[17:35:42] <Demure_> But then you don't need a lot of torque, right?
[17:35:57] <JT-Shop> I only need 12,700 mm/min so I over built it a bit lol
[17:36:14] <JT-Shop> just what ever it takes to move the gantry and Y axis
[17:36:22] <JT-Shop> or X axis as it is
[17:36:44] <Demure_> I see.
[17:37:13] <Demure_> To ideally make the parts I want I'd need to get close to 4000 mm/min, so perhaps that's out of range for now with steppers, but thanks for all the info
[17:37:22] <JT-Shop> can you change the 16T to a 20T
[17:37:53] <JT-Shop> that would be 1500mm/min
[17:38:22] <Demure_> Would going 1:1 make sense or do you lose a lot of torque on that with ballscrews?
[17:38:53] <JT-Shop> ballscrews have very little drag
[17:39:15] <Demure_> Hmmm.
[17:39:17] <JT-Shop> can you try some different ratios?
[17:39:31] <Demure_> Not that easily, but I have some other pulleys around that I might be able to try.
[17:40:09] <Demure_> Is there a minimum RPM for threading to do it's job or is it more of a scraping process?
[17:40:29] <Demure_> I could always try to drive my spindle way down to sub-200rpm
[17:40:38] <JT-Shop> I single point thread about 500 rpm
[17:41:20] <JT-Shop> as the thread pitch gets coarser I slow down also slow down for close shoulders
[17:41:48] <Demure_> I'm using a very fine depth, but multi-start to get the high 'pitch'
[17:42:27] <Demure_> Anyhow, I also need to get going for now, but thanks a ton, cleared things up a lot. :)
[17:42:32] <Demure_> Goodluck with work!
[17:43:48] <JT-Shop> thanks almost done for the day :)
[17:44:06] <Demure_> Have a nice evening then ;)
[17:47:18] <FloppyDisk525> where's a good place to get a corner rounding end mill? Need 0.1" or 3/32". was thinking I'd go w/ this:
[17:47:19] <FloppyDisk525> http://www.mscdirect.com/product/details/01826064
[17:47:25] <FloppyDisk525> For Delrin and mostly alum.
[17:48:18] <FloppyDisk525> I need to put radius on the top edge of the part, mostly avoided doing that because didn't want to fiddle w/ it...
[17:48:22] <JT-Shop> I like lakeshore carbide
[17:48:34] <FloppyDisk525> Thanks - will look them up^
[17:48:43] <JT-Shop> http://www.lakeshorecarbide.com/
[17:49:00] <FloppyDisk525> You've been watching that nyc cnc dude..
[17:50:23] <FloppyDisk525> I need to pick up some more endmills, either I have junk or just one and that doesn't 'cut' it (I'm pretty funny in my own head)
[17:50:47] <nubcake> good night everyone :)
[17:59:34] <Tom_itx> JT-Shop, your shed full yet?
[18:02:20] <JT-Shop> lol, no but I'm gaining room in here :)
[18:02:58] <Tom_itx> how's the spyder business been going?
[18:03:54] <Tom_itx> making any new addons?
[18:06:44] <JT-Shop> working on the NHR Carrier, finally got one done that I like
[18:07:14] <JT-Shop> http://gnipsel.com/images/Spyder/nhr-carrier/NHR%20Carrier%20V5%2002.jpg
[18:07:37] <JT-Shop> I've got it all done just need a new photo
[18:08:58] <JT-Shop> filling out customs forms :(
[18:11:57] <FloppyDisk525> Is that AlTiN coating better, same, worse for aluminum?
[18:13:46] <JT-Shop> http://www.lakeshorecarbide.com/2flute.aspx
[18:13:52] <JT-Shop> I use those for alum
[18:14:45] <FloppyDisk525> The 'end mills for alum' gives it away - thanks!
[18:16:49] <JT-Shop> I use two flute because my spindle is 6k max rpm
[18:17:02] <JT-Shop> the corner radius last the longest
[18:57:24] <MacGalempsy> JT-Shop: do you bend the steel or is it prefab material tha tyou weld onto?
[19:45:34] <Cromaglious_> ugh.. just replaced sway bar link bolts/buffers.. and noticed my CV boots are toast.. there goes another $150 for parts
[19:46:24] <Cromaglious_> next week... or next month
[20:01:38] <yasnak> its like they make the cv boots out of single ply tp
[21:12:26] <BeachBumPete> Evening linuxcnc :)
[21:14:44] <jdh> whuttup peet
[21:16:18] <BeachBumPete> Hey jdh howzitgoin?
[21:16:53] <jdh> the usual
[21:17:05] <jdh> haven't been to florida in weeks.
[21:17:09] <BeachBumPete> Oh I'm sorry ;)
[21:17:09] <jdh> or a week anyway
[21:17:28] <BeachBumPete> I was there today :)
[21:18:14] <BeachBumPete> I screwed up my can the other day
[21:18:22] <BeachBumPete> Van
[21:19:18] <BeachBumPete> Was working on my dashboard and accidentally cracked the little hazard button
[21:19:41] <BeachBumPete> Then my wife told me my taillights were out
[21:19:57] <BeachBumPete> So I checkd the fumes
[21:20:23] <BeachBumPete> Fuzes....damn autocorrect
[21:20:32] <jdh> sniffing fumes maybe
[21:20:41] <BeachBumPete> Heh probably
[21:20:50] <BeachBumPete> Anyway
[21:21:05] <BeachBumPete> Fuzes were good
[21:21:18] <BeachBumPete> So I got some new taillight bulbs
[21:21:41] <Tom_itx> is there a way to turn a SW rendering back into a model?
[21:21:51] <BeachBumPete> One of them Was kinda corroded so I pulled them both and still no taillights
[21:22:01] <pfred1> Tom_itx very carefully
[21:22:10] <Tom_itx> how would i go about it?
[21:22:13] <CaptHindsight> Tom_itx: what kind of file do you have?
[21:22:28] <BeachBumPete> Then I realized that the little hazard button does not stay locked down anymore for some reason
[21:22:46] <pfred1> Tom_itx when you find out you let me know because how I do it sucks
[21:22:56] <Tom_itx> CaptHindsight, my kid want's to do some engraving at school
[21:22:58] <BeachBumPete> If you hold it down taillights work again
[21:23:02] <Tom_L> https://grabcad.com/library/playing-card-1
[21:23:15] <BeachBumPete> Damn new switch is like 150$
[21:23:22] <Tom_itx> he wanted to engrave a royal flush on the back of a part
[21:23:29] <pfred1> BeachBumPete everybody loves money
[21:23:38] <Tom_itx> i found that on grabcad
[21:23:47] <BeachBumPete> Yeah so do I
[21:23:48] <CaptHindsight> you guys like money to!?
[21:24:16] <pfred1> Tom_itx I import the image into inkscape then manually trace it because inkscapes trace bitmap feature kinda doesn't work too swift for me
[21:24:17] <BeachBumPete> So I'm pissed off at me
[21:24:33] <Tom_itx> meh, it's hardly worth that
[21:24:40] <pfred1> you're telling me?
[21:24:51] <pfred1> I told you how i do it sucks
[21:24:55] <jdh> that's whack. hazard lights are the most useless thing on a car
[21:25:13] <CaptHindsight> BeachBumPete: did you experience any hurricane fun?
[21:25:13] <pfred1> jdh until you're broke down on the side of a highway
[21:25:26] <jdh> still worthless
[21:25:37] <BeachBumPete> Yeah well apparently the hazards are integrated into the whole turn signal and int wiper switch
[21:25:44] <pfred1> well just plain lights folks will run right into you then
[21:26:02] <jdh> I could see the turn signal integration, but wiper?
[21:26:02] <BeachBumPete> Capt no not really
[21:26:16] <pfred1> I rewired a whole car once
[21:26:19] <CaptHindsight> Tom_itx: is it a jpg or similar image or do you still have the native sw file?
[21:26:20] <BeachBumPete> Yeah it is all one the one stalk
[21:26:20] <jdh> I really hate when people turn them on driving on the interstate in the rain
[21:26:34] <pfred1> I turned a 1966 into a 1973
[21:26:51] <pfred1> because how they did it in 66 really blew
[21:27:09] <BeachBumPete> Vw?
[21:27:14] <pfred1> Volvo
[21:27:29] <pfred1> I turned a 66 P1800D into a 73 142
[21:27:34] <pfred1> P1800S even
[21:27:40] <CaptHindsight> 66 Volvo now thats a thing of beauty
[21:27:43] <pfred1> at least electrically
[21:27:49] <BeachBumPete> I like the
[21:27:55] <BeachBumPete> P1800
[21:28:08] <pfred1> I had the whole harness out of a 73 and the 66 wirign was shot to hell
[21:28:28] <pfred1> yeah they're OK I've had a couple
[21:29:00] <pfred1> I still got my 66 I chopped up my 67
[21:29:17] <CaptHindsight> pfred1: did you go with 12 or 13 volts? :)
[21:29:22] <Tom_itx> CaptHindsight, i'm not sure.. just downloading it now
[21:29:27] <Tom_itx> i doubt it's jpg
[21:29:50] <CaptHindsight> renderings are usually just images
[21:30:04] <BeachBumPete> Maybe I can drive while holding down the hazard button all the way to work tomorrow ;)
[21:30:18] <Roguish> hey, all. is it possible to run machine calibrate from a command line?
[21:30:24] <jdh> pete: pretend it is a BMW and jsut don't use turn signals
[21:30:42] <pfred1> no one uses directionals here
[21:30:45] <BeachBumPete> Turn sgnals work fine just no brake lights
[21:31:02] <CaptHindsight> use hand signals
[21:31:09] <pfred1> brakes shouldn't be on the turn signal circuit
[21:31:13] <BeachBumPete> Driving lights work
[21:31:21] <pfred1> it is a different filament
[21:31:26] <jdh> what are you working on/at?
[21:31:34] <pfred1> brakes are brighter
[21:31:49] <BeachBumPete> Tell that to chevy
[21:31:51] <CaptHindsight> http://blog.esurance.com/wp-content/uploads/driving-signals.jpg
[21:32:02] <pfred1> 3 pounds of dirt makes my Chevy heavy
[21:32:16] <BeachBumPete> Love my astro
[21:32:37] <BeachBumPete> Respect the van man
[21:32:57] <Tom_itx> bmp
[21:32:59] <pfred1> I did some hot rod work on a buddy of mine's 70 327 Chevelle
[21:33:23] <BeachBumPete> Mebbe I can jam something in beside the switch and keep it down
[21:33:26] <pfred1> when he first got that car i looked at him and said, This is a V8?
[21:33:34] <jdh> duct tape it down
[21:33:50] <pfred1> by the time he got rid of it i think he was scared of it
[21:33:54] <BeachBumPete> It's pretty strong spring in there
[21:34:19] <BeachBumPete> Not sure taps would work
[21:34:33] <BeachBumPete> Tape
[21:34:52] <jdh> daisy chained tie-wraps
[21:35:12] <BeachBumPete> Hmm that's not a terrible idea
[21:35:24] <jdh> big hose clamp
[21:35:49] <BeachBumPete> I gotta order the new switch anyway might take a few days to get it
[21:36:08] <pfred1> is it the switch on the pedal?
[21:36:37] <BeachBumPete> No it's the red hazard button on the steering wheel base
[21:36:54] <BeachBumPete> Probably exactly the same as in your suburban
[21:37:16] <pfred1> can't get one at a junk yard?
[21:37:38] <BeachBumPete> Have not tried just figured out the problem tonight
[21:37:49] <pfred1> a buddy of mine had an S-10 and he wanted a motor for it when he called aroudn to junk yards they said sorry they all come in with blown motors
[21:38:13] <pfred1> that was his cue to get rid of that ride
[21:38:47] <BeachBumPete> I've had pretty good luck with three different Astros over many years
[21:38:57] <MacGalempsy> good evening
[21:39:06] <BeachBumPete> Hey mac
[21:40:21] <BeachBumPete> Well gn8
[21:40:26] <MacGalempsy> oh
[21:40:30] <MacGalempsy> see ya pete
[21:40:48] <FloppyDisk525> MacGalempsy - where are you located?
[21:40:57] <MacGalempsy> well, got the computer moved to the new location
[21:40:58] <FloppyDisk525> thought maybe you were in CA>
[21:41:26] <MacGalempsy> left Cali when I was 28 and only visit on holidays
[21:41:31] <MacGalempsy> im in Arkansas now
[21:41:32] <pfred1> my controller PC did some weird stuff on me tonight

[21:42:04] <MacGalempsy> I may have to move the computer one more time, but maybe I can get the edm between the monitors and the CNC
[21:42:43] <MacGalempsy> the brown box on the wall will likely need to come down
[21:43:42] <FloppyDisk525> Oh, somehow I thought you were out in CA...

[22:31:01] <pfred1> check out the USS ponce
[22:31:10] <pfred1> it has a battlefield laser system on it
[22:31:23] <pfred1> it can burn missiles otu of the air
[22:31:37] <MacGalempsy> ponce como la cuidad en puerto rico?
[22:31:49] <pfred1> yeah the name is pretty funny
[22:32:06] <MacGalempsy> asi Ponce De Leon
[22:53:08] <MacGalempsy> tienes un buena noche. chau
[22:56:31] <Cromaglious_> that's insane!
