Back
[00:02:44] <furrywolf> tomorrow's project is lawyers... then if I have spare time, fuel pressure gauge for subaru, then new fuel filters, then new fuel pump, as needed.
[00:28:00] <furrywolf> bbl, wolfy bedtime
[01:24:33] <pink_vampire> hi
[01:31:04] <SEL> hi
[01:33:58] <SEL> https://www.youtube.com/watch?v=r91UvZDigLY
[01:54:40] <pink_vampire> coolant is toxic?
[01:55:12] <archivist> only if it is toxic
[01:57:46] <pink_vampire> I'm thinking about using coolant, but I dont know how to prevent it from going going to the floor
[01:58:18] <archivist> build a case around the machine
[02:00:16] <pink_vampire> but there is 4 bolts that go through the base and the stand.
[02:00:52] <pink_vampire> i will get dripping of collant...
[02:03:40] <archivist> seal with silicon/mastic
[02:08:52] <Deejay> moin
[02:10:13] <pink_vampire> hi Deejay
[02:10:20] <Deejay> hi pink_vampire
[02:11:10] <pink_vampire> there is a temporary sultion for collant?
[02:13:18] <pink_vampire> archivist: ?
[02:35:19] <KimK> pink_vampire: doesn't your machine have a table trough/gutter and a drain? If not, maybe you could build a box (with door/doors) to capture the coolant before it gets very far? (Would help limit slinging too, unless you expect to use only very low spindle speeds.)
[02:35:59] <KimK> s/a box/a box around the table and spindle/
[02:36:25] <pink_vampire> KimK: I have the G0704
[02:36:39] <pink_vampire> http://www.grizzly.com/products/Drill-Mill-with-Stand/G0704
[02:40:37] <KimK> Ah, OK, thanks for the pix. It looks like it has a very small lip already, does it have a small drain? If so, you only need some furnace tin or bendable plastic sheets to put under the table overhangs, to catch what drips off the table. That won't stop the flinging, of course.
[02:45:29] <KimK> You'll need other stuff for that. Similar to the battle a Bridgeport-sized mill operator must fight if he insists on using flood coolant. It can be done, at least if quantities and production rates are low. All the medium-sized machines and up are "tin boxes" suitable for putting a lawn sprinkler under the spindle and keeping the rest of the room dry.
[02:47:30] <KimK> Does any of that help you?
[02:47:57] <pink_vampire> the table has a place for drain.
[02:48:33] <pink_vampire> but i will need to make something bigger that will cover more area.
[02:49:45] <pink_vampire> BRB
[02:50:47] <KimK> Well, OK, there you go! Just keep in mind to catch the table drippings (that will go on the floor if you let them fall) and drain them back to the pan. Also, that's a pretty shallow pan (what, 10mm? 1/2"?) so your machine had better be pretty level.
[02:56:10] <KimK> And the drain hose goes down to a container on the floor. What, a 5 gallon bucket with a "Little Giant" submersible pump in it? Put 2 gallons of coolant in it (enough to always cover the pump) and call it good. Top off as needed.
[03:05:10] <Wolf_> I was going to set my mill on a commercial baking pan/tray and use that to catch the overflow, granted I already have one laying around
[04:07:50] <sabir> hi

[05:59:37] <XXCoder> shhhh
[06:21:21] * Loetmichel is getting old... now i need "six eyes" to solder well... -> http://www.cyrom.org/palbum/main.php?g2_itemId=15963
[06:22:06] <anomynous> what are you soldering there
[06:22:13] <Jymmm> kybd
[06:23:08] <Jymmm> Loetmichel: This is what I use when working on small parts http://www.harborfreight.com/magnifier-head-strap-with-lights-38896.html
[06:34:18] <Jymmm> Loetmichel: These are bad either http://www.harborfreight.com/fluorescent-magnifying-lamp-60643.html
[06:34:34] <Jymmm> Loetmichel: These aren't bad either http://www.harborfreight.com/fluorescent-magnifying-lamp-60643.html
[06:41:35] <Loetmichel> anomynous: just soldering 450 new and longer usb cables to keynoards... (shielded of course)
[06:42:12] <anomynous> preventing spying from naighbour?
[06:42:18] <anomynous> neighbour*
[06:42:33] <Loetmichel> customer
[06:42:44] <Loetmichel> we make tempest safe tech
[06:46:21] <SpeedEvil> I can make any desktop computer workstation completely safe from tempest in 20 minutes with my patented solution.
[06:46:36] <SpeedEvil> 2m copper sheet cube, with UPS, and you solder the user inside.
[06:47:22] <Jymmm> That's overkill.... just wrpa everything/body in brass screen and ground it all =)
[06:48:49] <Jymmm> SpeedEvil: https://www.schneier.com/blog/archives/2005/09/snooping_on_tex.html
[06:49:22] <SpeedEvil> Jymmm: the user is a major security leak, you can't let them out again.
[06:49:28] <SpeedEvil> yeah - heard that
[06:49:52] <Jymmm> SpeedEvil: Disposable users, I kinda like the sound of that, sorta.
[06:50:17] <Jymmm> SpeedEvil: Isn't that what Home Depot uses for empoyees?
[07:06:10] <ganzuul> Silver solder is REALLY expensive.
[07:06:22] <ganzuul> Bought 1 rod locally. 20e.
[07:07:00] <Loetmichel> ganzuul: hmm. its 6 eur over here per rod..
[07:07:21] <Loetmichel> at the local tool shop
[07:07:43] <SpeedEvil> ganzuul: silver is pretty expensive
[07:07:50] <SpeedEvil> ganzuul: how heavy a rod?
[07:07:54] <ganzuul> 1.5 mm
[07:08:00] <SpeedEvil> that is not a weight
[07:08:13] <ganzuul> hm
[07:08:21] <ganzuul> It has flux on it too
[07:08:33] <SpeedEvil> silver is ~$15/oz
[07:10:06] <Sync> if you buy just one no wonder it is spendy :D
[07:11:12] <SpeedEvil> ebay is reasonable in general
[07:12:25] <Sync> I had no problems buying from unicore directly
[07:13:30] <SpeedEvil> I mean for very, very small quantities.
[07:13:35] <SpeedEvil> As in several bandsaw blades
[07:13:37] <ganzuul> http://www.ceweld.nl/en/product/l-ag55sn
[07:14:21] <ganzuul> They had it in an open package on the shelf. Told me I can buy just one.
[07:15:14] <Sync> I bought some brazetec cb4
[07:15:19] <Sync> AgCuTi alloy
[07:16:35] <Sync> 1kg of ag55sn is around 350€
[07:26:50] <ganzuul> Well, I'ma compare how it behaves to cheaper alloys.
[07:28:39] <ganzuul> ...That sentense structure didn't turn out right.
[07:28:52] <lair82> cpresser, you around?
[07:30:41] <SpeedEvil> Annoyingly silver solder, the more silver, the better.
[07:30:44] <SpeedEvil> (in many ways)
[07:33:40] <Sync> yep
[07:39:18] * Loetmichel just got delivered with 3*1m piece of "vilmil"... will test if its any good this evening
[07:39:20] <Loetmichel> :-)
[07:55:25] <ganzuul> Looks like you can use brass and bronze to weld steel... Silver solder is nice for stainless and very close tolerances.
[07:55:43] <ganzuul> ~braze steel
[07:55:52] <SpeedEvil> silver solder is awesome - it is in many ways better than welding for - for example bandsaw blades
[07:56:04] <ganzuul> :o
[07:57:56] <ganzuul> ...how?
[07:58:56] <Tom_itx> lower melting temp
[07:59:00] <Tom_itx> doesn't anneal the blade
[08:00:04] <ganzuul> oic
[08:04:06] <JT-Shop> we are getting your rain now Tom_itx
[08:04:51] <Sync> ganzuul: silver solder has higher capillary activity
[08:07:49] <ganzuul> Welding is a lot of metallurgy...
[08:12:00] <Sync> welding != brazing
[08:13:31] <ganzuul> I know, but metal turn liquid in both.
[08:15:20] <ganzuul> I have learned about things like how austensite isn't magnetic, and carbon precipitation. Now that I'm learning more about brazing I'm getting interested in welding too.

[08:25:34] <pink_vampire> https://i.chzbgr.com/full/4556758528/h67B42BBC/
[08:40:57] <ganzuul> SpeedEvil: He didn't use a lot of it.
[08:41:23] <SpeedEvil> ganzuul: no, doesn't need a lot for small area joints
[08:43:25] <pcw_home> lair82:
[08:43:26] <pcw_home> cant see any problem here, same FPGA card, same bitfile (7i80hd_16_rmsvss6_8.bit) linuxcnc 2.7 pre6 5 sserial daughtercards
[08:43:28] <pcw_home> http://filebin.ca/2EyWKZWDfCem/lots_of_pins
[08:43:28] <ganzuul> This is brilliant: https://www.youtube.com/watch?v=onHkk7kyd6c
[08:43:29] <pcw_home> (lots and lots of pins because that's 4 Ethernet FPGA cards running at once. The 7I80.0 is the one with your config and the 7I44 and 5 sserial remotes)
[08:44:10] <lair82> pcw_home, i was just reading thru the log from yesterday, think it's the 7i44?
[08:44:24] <pcw_home> not sure
[08:47:13] <pcw_home> 7I44s are pretty simple and rugged
[08:47:42] <lair82> pcw_home, that doit fault, that is an issue with my cpu?
[08:47:57] <pcw_home> thats a real time issue
[08:49:31] <lair82> This is a carbon copy build, other than the 7i44 compared to the machine at the shop that I am finishing up, not sure where to go with the doit fault
[08:49:45] <lair82> MB?
[08:50:19] <lair82> I have the servo period at 1500000
[08:50:25] <lair82> in my ini
[08:50:45] <pcw_home> it means the hm2 write cycle at the end the previous servo thread was so late that
[08:50:46] <pcw_home> the sserial read data was not available at the beginning of the current thread
[08:51:36] <Sync> SpeedEvil: most bandsaws have a resistance welder built in
[08:51:48] <SpeedEvil> Sync: for some definition of bandsaw
[08:51:54] <pcw_home> run a latency test or histogram
[08:53:21] <pcw_home> make sure all power management, cstates, cool&quiet etc are turned off in the BIOS
[08:54:03] <Sync> true SpeedEvil
[08:54:09] <lair82> pcw_home , in my hal file, should I have the addf hm2_7i80.0.write right below the addf hm2_7i80.0.read line, or should I have that after all of the rest of the addf's?
[08:54:42] <lair82> I just double checked all the bios stuff, it is identical to my other machine
[08:55:14] <Jymmm> lair82: including bios version?
[08:55:21] <pcw_home> the I/O write should always be the last thing
[08:56:23] <lair82> just started the latency test when you told me, 4 mins ago, and I have servo thread= 485753, and base thread=330520
[08:56:33] <pcw_home> otherwise things like the servo PID loop will be funkadoric
[08:56:55] <lair82> I will have to check the bios version, I am not sure
[08:56:57] <pcw_home> Yuck, thats terrible latency
[08:57:11] <lair82> Perfect
[08:57:19] <pcw_home> try without the base thread
[08:57:27] <lair82> how?
[08:57:55] <lair82> I don't start it from the command line
[08:58:37] <pcw_home> well you need to start it from the command line to be able to set options
[09:01:31] <lair82> Got it, and its climbing
[09:01:38] <lair82> 44325
[09:02:05] <pcw_home> run a youtube video
[09:02:45] <pink_vampire> lol https://youtu.be/4I0rkEjkipU
[09:03:23] <lair82> just trying to start a youtube video, 276723
[09:05:16] <tjtr33> andypugh, is this paraphrasing correct ? "Max Power (measured in watts) = Max Accel ( measured in m/s2) * Max Velocity (measured in m/s) * Mass (measured in kg)"
[09:06:10] <Jymmm> tjtr33: The answer is 42, doesn't matter what the questions is.
[09:06:21] <SpeedEvil> No, I think you've got a 'g' missing in there.
[09:06:22] <SpeedEvil> err
[09:06:25] <SpeedEvil> never mind
[09:06:56] <SpeedEvil> Force = accel * kilos, and velocity * force = power, so that looks right
[09:07:30] <tjtr33> Jymmm, ever hear the Goon Show say "Jeeeeeyim?" ( where Peter Sellers got famous )
[09:07:52] <pcw_home> the latency issue is probably not realted to the sserial 4,5,6,7 channel
[09:07:52] <Jymmm> tjtr33: never
[09:07:53] <pcw_home> issue but its definately related to the "doit not cleared" message
[09:09:00] <lair82> Ok, I will look at the bios vers, and see if there isan update
[09:10:06] <lair82> This is the exact same mb, and APU, as the other machine, I just don't remember if I updated the bios, that was last december
[09:14:07] <pcw_home> btw heres a good preempt-rt motherboard latency plot:
[09:14:08] <pcw_home> http://freeby.mesanet.com/h97-g3258-preemt-rt.png
[09:15:50] <lair82> They have made 5 bios updates since the version on this board, I just don't know what's on the board at the shop
[09:16:13] <lair82> Might be going back to the shop to look at that machine
[09:16:37] <lair82> and grab another 7i44
[09:27:19] <Wolf_> wow, 276k?
[09:29:02] <Wolf_> … I watch youtube on my linux box while milling 0.o
[09:32:57] <tjtr33> seems that asus h97 mobo with pentium g3258 is popular with uberclockers
[09:33:30] <tjtr33> do you read that base thread latency as 15uS or 7.x uS ? cuz its +/- on graph
[09:36:37] <pcw_home> 7 usec
[09:38:19] <pcw_home> RTAI is better naturally
[09:46:35] <lair82> Now, 1 session of Glxgears, youtube watching the hexapod parallel robot demo, it was running at 23000, then it just spiked at 291285
[09:48:40] <lair82> What does this do? radeon.modeset=0, I found this in the http://wiki.linuxcnc.org/cgi-bin/wiki.pl?TroubleShooting#APM_and_ACPI_bios_settings
[09:55:14] <ganzuul> lair82: With ati/amd issues on Linux, it's best to not fix it if it ain't broke.
[09:55:19] <ganzuul> Really fiddly.
[09:55:39] <ganzuul> Not UNIXesque at all.
[09:55:59] <ganzuul> And just riddled with footguns.
[09:56:25] <ssi> footguns?
[09:56:38] <lair82> I have horrible latency on this machine
[09:56:59] <ganzuul> A gun designed to shoot yourself in the foot with.
[09:57:28] <lair82> just trying eliminate all possible culprits
[09:58:06] <ganzuul> lair82: Can you try in framebuffer/failsafe graphics mode?
[09:58:42] <lair82> What is a good board to run, with debian wheezy, using a 7i80?
[09:58:56] <lair82> ganzuul, I don't follow
[10:03:25] <ganzuul> Your distro probably has a failsafe graphics option in the GRUB boot menu. You can use it to quickly test if it makes a difference compared to the radeon driver.
[10:03:45] <ganzuul> I don't know why you are suspecting your radeon driver, though.
[10:03:56] <lair82> ganzuul, I am using Debian Wheezy,
[10:04:17] <ganzuul> IIRC Wheezy has that.
[10:04:26] <lair82> It was what I read in the http://wiki.linuxcnc.org/cgi-bin/wiki.pl?TroubleShooting#APM_and_ACPI_bios_settings
[10:10:51] <CaptHindsight> lair82: is this the same AMD hardware setup that you have been using except for the 7i44?
[10:11:01] <lair82> yes
[10:11:29] <CaptHindsight> are you using the new 2.7 release or the same Linuxcnc version as last year?
[10:12:04] <lair82> I don't remember the exact latency values, but I haven't had any of the issues that I am having now. I just updated this thing about 2 weeks ago
[10:12:34] <CaptHindsight> lair82: are you using the new 2.7 release or the same Linuxcnc version as last year?
[10:13:29] <lair82> No, but I did a git pull, and re-compiled 2 weeks ago
[10:14:03] <CaptHindsight> I don't understand the answer
[10:14:33] <ganzuul> He used a beta version and not the release version.
[10:15:08] <lair82> I am running master, and it is current as of 2 weeks ago
[10:15:09] <ganzuul> Could be a non-clean install issue.
[10:16:11] <lair82> Re-install Debian?
[10:16:27] <ganzuul> No...
[10:17:13] <ganzuul> It's actually really tedious to revert make install.
[10:17:34] <Wolf_> current version is less then a week old
[10:17:54] <ganzuul> Unless the makefile has a make uninstall option and you preserved the build dir.
[10:18:34] <lair82> I built a RIP
[10:18:53] <ganzuul> But still, if it is an unclean install issue then the old version which you replaced is still there, causing issues.
[10:19:31] <lair82> So should I delete the entire linuxcnc-dev directory, and start over?
[10:19:42] <ganzuul> TBH, reinstalling debian might be simpler. o.o
[10:20:15] <ganzuul> I couldn't tell you. This is just general Linux build env. advice.
[10:20:20] <Wolf_> ^ screw all the fiddling and use live disk install?
[10:20:34] <cradek> unless you're doing development, you should use packages
[10:20:36] <ganzuul> +1
[10:20:43] <lair82> I am up for anything, the customer keeps asking what is going on, and when he will see the machine move
[10:20:46] <CaptHindsight> +2
[10:20:56] <ganzuul> Test with that before doing something complex and dangerous.
[10:22:17] <lair82> I understand that, but I we have always had some crazy shit going on, patches etc, so I have always built from source. If it's easier to build from the buildbot, I am all for it, but I have never done that, so I am not sure where to start.
[10:22:19] <Wolf_> I took a 7-8yr old computer that was in my shop, tossed a $20 vid card in it, and now I have it running my mill while watching youtube on it and chatting in here
[10:22:41] <cradek> can you stop doing "crazy shit", and use released versions?
[10:22:57] <cradek> right now I'd try hard to use 2.7.0
[10:24:08] <lair82> I don't see why not, I am not doing anything special on this machine, basic 3 axis vmc, using a 7i80 mesa setup
[10:24:52] <Wolf_> the mention of customer, even more reason to use simple install imo
[10:25:55] <Wolf_> my upgrade from 2.7 pre7 to 2.7.0 was just clicking a red ! icon (I’m a linux noob)
[10:26:15] <cradek> yay
[10:26:47] <ganzuul> There is a lot of black magic which goes into turning a build into a package. Some distros are special snowflakes, with special needs.
[10:27:03] <Wolf_> seems so
[10:27:59] <Wolf_> should have seen me fighting with it for a hour hunting down all the stuff I thought I needed to add in to make things work… just to find out its all installed already w/ the iso live disk lol
[10:28:36] <lair82> Totally agree, but that is how I have always done it, we started 3 years ago, with no experience doing this stuff, and jumped right off the cliff with this stuff, with patches on our turning centers for the tool tables, we don't even use patches any more, but because thats how I learned, every time I try to do some thing different or new, I end up in more hot water than when I started
[10:28:36] <Wolf_> only thing I couldn’t get working was my logitech keyboard
[10:29:10] <ganzuul> That is the story with a lot of complex Linux-based production software. GNU Radio is a good/bad example of this.
[10:29:38] <lair82> Thats why I build from the terminal on every machine
[10:33:33] <lair82> I am going to run back to the shop to get some stuff, then come back and start over from the beginning using the debian iso I have on a thumb drive, and build using the buildbot, sound like a plan or no?
[10:33:46] <ganzuul> That sounds good.
[10:33:59] <lair82> Or can I fix things without re-installing debian?
[10:34:06] <ssi> reinstall. start clean
[10:34:15] <Wolf_> if you are redoing everything, might as well try the iso install
[10:34:27] <ssi> I agree
[10:34:38] <ssi> livecd install, then let it update itself to 2.7.0
[10:34:46] <Wolf_> not much time loss is it doesn’t work
[10:35:02] <lair82> OK, will be back in about 40 mins,
[10:37:17] <Wolf_> lol my biggest problem with the live cd install was getting internet working, but that turned out to be a issue when moved some networking stuff around and added a new switch to the mess (felt kinda dumb when I figured it out)
[10:40:21] <CaptHindsight> is the new 3.7 ISO using Debian 8 Jessie or Debian 7 Wheezy?
[10:41:35] <skunkworks> wheezy (2.7)
[10:41:40] <CaptHindsight> Wheezy nevermind
[10:41:48] <CaptHindsight> thanks
[10:42:21] <skunkworks> you're welcomer
[10:46:51] <ssi> welcomer than what?!
[10:48:05] <ganzuul> the welcomest
[10:48:16] <ssi> welcomer than the welcomest?
[10:48:22] <ssi> that's pretty dang welcome
[11:30:43] <CaptHindsight> where will I find a better selection of small soft runner balls, toy store or pet store? I haven't been to either in a while
[11:31:08] <CaptHindsight> the balls are used a a wrench to remove the backs of watches
[11:31:23] <CaptHindsight> runner/rubber
[11:31:49] <ssi> what about a watch case wrench? :P
[11:32:17] <CaptHindsight> the balls are ~$200 lower cost
[11:32:20] <ssi> http://www.ebay.com/itm/like/221629667391?ul_noapp=true&chn=ps&lpid=82
[11:32:22] <ssi> are they? :D
[11:32:32] <CaptHindsight> for Rolex they are
[11:32:53] <archivist> mine is hard plastic
[11:33:40] <archivist> and most people use a proper spanner in a stand
[11:34:27] <CaptHindsight> http://i.ebayimg.com/00/s/MTIwMFgxMjAw/z/rIAAAOSw8d9UyIvA/$_57.JPG for backs that have those large notches
[11:35:42] <CaptHindsight> https://www.youtube.com/watch?v=PxF0O6Z3dYA open any watch with a screw back
[11:37:31] <archivist> watch was not properly tight!
[11:37:38] <ssi> archivist: +1
[11:38:34] <CaptHindsight> probably wasn't welded on either
[11:39:13] <CaptHindsight> but works well

[11:41:42] <CaptHindsight> the secret is out
[11:41:45] <ssi> china is amazing
[11:42:02] <ssi> High quality and handfeel.
[11:42:05] <ssi> .Plastic Ball do not scratch you watch
[11:42:09] <ssi> Press the ball ,and rotate it to the right way.
[11:42:12] <ssi> After Opening the case it can play as a normal ball
[11:42:22] <ssi> Please Note：Sometime may be the ball has a cartoon picture on it. And the cartoon picture of the ball is at random. Also,sometime may be no pattern on it.
[11:42:22] <CaptHindsight> 2 in 1 !

[11:45:57] <CaptHindsight> https://thewatchbloke.files.wordpress.com/2015/01/p1010438a.jpg they make a socket set for these
[11:46:00] <archivist> front page image shows the correct tool http://www.ebay.co.uk/itm/OFFICIAL-ROLEX-1008-CASE-OPENER-OPENING-TOOL-INSTRUCTIONS-/321753362382
[11:46:42] <ssi> at least you can get the instructions for the correct tool for only $250!
[11:46:51] <CaptHindsight> http://www.ofrei.com/images/ofrei-213.jpg
[11:47:18] <archivist> ssi cheaper to bid on an old CMM
[11:47:37] <CaptHindsight> http://media1.riogrande.com/Products/Images/Medium/113884.jpg the whole jig
[11:47:39] <ssi> pete and I found an old CMM rotting in a scrapyard last year
[11:48:06] <archivist> I have 10 minutes to make up my mind
[11:48:35] <archivist> an old brown and sharpe
[11:48:36] <ssi> get it
[11:48:54] <archivist> effin heavy probably
[11:48:55] <ssi> link?
[11:49:12] <archivist> http://www.ebay.co.uk/itm/221868431124
[11:49:20] <archivist> 12 miles from me
[11:50:00] <ssi> oh yes I'd definitely be getting that if it were that cheap and that close
[11:50:09] <ssi> worth it for parts if nothing else
[11:50:31] <archivist> true
[11:52:10] <archivist> might have to take it to bits just to move it
[11:52:20] <ssi> doesn't look THAT heavy
[11:52:30] <ssi> small granite base, light machine
[11:52:35] <ssi> the big control rack might be 800lb
[11:52:50] <ssi> that's about what the control rack on my hardinge weighed when I got it
[11:52:58] <archivist> I think the rack is a lot lighter than that
[11:53:03] <ssi> but most of that was the huge ass power supplies; the servo supply and the 50A 5V ttl supply
[11:53:55] <archivist> worth it just for scales
[11:54:12] <ssi> yep
[11:58:17] <archivist> oops
[11:58:19] <archivist> :)
[11:58:50] <archivist> now I am in trouble, have to make space
[11:59:23] <CaptHindsight> heh, you could have worse problems
[11:59:36] <archivist> mebe
[11:59:37] <CaptHindsight> but well worth it even in parts
[12:00:30] <archivist> the lake of probe is a dont care as I won one the other week
[12:05:57] <ssi> congrats :)
[12:06:09] <archivist> so far I have not found any images of that model on the interwebs
[12:41:35] <_methods> https://www.dropbox.com/s/vfvt7g35gh9hwat/2015-09-09%2013.17.08.jpg?dl=0
[12:41:41] <_methods> $1k
[12:41:42] <_methods> hahah
[12:45:55] <_methods> and a bridgeport for $200
[12:45:57] <_methods> https://www.dropbox.com/s/dxkk4k52s0yv1i6/2015-09-09%2013.20.15.jpg?dl=0
[12:47:11] <ssi> _methods: where?
[12:47:19] <_methods> auction
[12:47:39] <_methods> almost missed the bridgeport
[12:47:48] <ssi> did you buy it?
[12:47:51] <_methods> yeah
[12:47:54] <ssi> nice
[12:48:01] <_methods> that height gauge and mill
[12:48:17] <ssi> worth it
[12:48:21] <_methods> the height gauge was still wrapped in it's original bag
[12:48:58] <_methods> https://www.dropbox.com/s/jx0v32oqwyakub1/2015-09-09%2013.17.01.jpg?dl=0
[12:50:50] <_methods> it's an older bridgeport with the square ways though
[12:51:44] <ssi> all square ways, or just the saddle?
[12:51:50] <_methods> all
[12:51:53] <ssi> my enco clone has square ways on the saddle but the table is dovetail
[12:51:57] <ssi> and the knee
[12:52:06] <_methods> it's all square
[12:54:31] <_methods> has the column extension too
[12:55:01] <_methods> the funny thing is at the auction there was a POS acer mill that was brand new and went for like $9500
[12:55:19] <_methods> then the bridgeport goes for $200 lol
[12:55:22] <_methods> morons
[12:55:31] <CaptHindsight> Brand name
[12:55:41] <archivist> must be auction gloat day :)
[12:55:46] <_methods> oh yeah?
[12:55:55] <_methods> who else won the auction wars hehe
[12:56:03] <archivist> me http://www.ebay.co.uk/itm/221868431124
[12:56:16] <CaptHindsight> like most things today, the consumer indoctrination has succeeded
[12:56:30] <_methods> wow what'd you score that for?
[12:56:42] <_methods> oh 100.00
[12:56:58] <CaptHindsight> I got brake pads for $13 delivered :)
[12:57:09] <_methods> old school cmm
[12:57:47] <archivist> but just about affordable for me and small enough
[12:58:19] <archivist> how old, found no info yet
[12:58:41] <_methods> what how old the cmm is?
[12:58:52] <archivist> yes
[12:59:12] <_methods> it's before my time i know that lol
[12:59:14] <archivist> I am assuming 1980s
[12:59:33] <archivist> or even earlier
[12:59:45] <_methods> girls still had cooties when that came out in my lifespan
[13:00:04] <archivist> maybe as old as your bridgport
[13:00:12] <_methods> hehe
[13:00:21] <ssi> _methods: when did girls stop having cooties?! :(
[13:00:48] <_methods> hahahah
[13:00:53] <_methods> well i guess that depends
[13:09:21] <_methods> yeah i can't find anything on the micropcr cmm
[13:10:00] <_methods> except a mention in brown and sharpe's discontinued products list lol
[13:10:10] <archivist> I have done a few searches and found nothing
[13:32:42] <CaptHindsight> looks like they have done a pretty good job of deleting it from history
[13:36:06] <CaptHindsight> looks like it was still a current model in 1999
[13:37:59] <CaptHindsight> archivist: I just found some accuracy specs is all
[13:38:11] <CaptHindsight> in a 1999 buyers guide
[13:39:02] <CaptHindsight> http://www.readbag.com/qualitydigest-pdfs-cmm
[13:43:03] <CaptHindsight> http://www.chmetrology.co.uk/index.html and these guys still hold training classes on the software
[13:52:30] <pcw_home> so its a robot CMM 40 uinch repeatability 1 PPs
[13:57:25] <archivist> odd to call that a robot
[13:58:00] <archivist> but the working volume stated on fleabay does not match that line
[14:02:54] <archivist> hmm better go dig out a book or two, "Inspection machines, measuring systems and instruments" seems worth looking in
[14:04:12] <pcw_home> automatic as opposed to manual I guess they mean
[14:05:00] <pcw_home> like a weak CNC machine
[14:12:24] <archivist> just looked in that book, was probably too old at 1978
[14:28:58] <furrywolf> meh. if even picking a lawyer is this hard, dealing with one is going to be even harder.
[14:29:22] <CaptHindsight> sounds like fun
[14:30:19] <CaptHindsight> it's never reaffirming when you're already getting bad signals from the lawyer on your side that you haven't hired yet
[14:31:27] <CaptHindsight> what's worse is when they sound confident before the check clears and then later make it sound like you knew it was a big gamble all along
[14:32:29] <furrywolf> I haven't talked to any of them yet... just trying to look at reviews and websites for the one who seems least full of shit. :P
[14:32:37] <archivist> did you start wit do you do pro bono
[14:32:42] <furrywolf> one of them obviously wrote all his own reviews, for example... not going to go to that guy.
[14:40:46] <CaptHindsight> are there any accident attorneys on the local TV channels? They have to pay for those so I imagine they try to get as much as possible in settlements.
[14:42:09] <furrywolf> dunno, I don't watch TV.
[14:42:36] <_methods> better call saul
[14:43:09] <furrywolf> also, I'm not trying to get a million dollars... just the work I missed and a few bucks to let me take more time off later to catch up on everything I missed out on because my back hurt too much.
[14:43:13] <furrywolf> saul?
[14:43:26] <CaptHindsight> some are quite humorous since they make use of cheezy video effects
[14:44:06] <CaptHindsight> reminds me of MTV in the 80's
[14:46:09] <tiwake> anyone know what kind of electrical component this is? https://www.dropbox.com/s/xggunqk8bk4d1jw/20150909_002.jpg?dl=0
[14:46:28] <tiwake> the 2046
[14:47:05] <furrywolf> it's a "don't use dropbox because it fucking sucks" component.
[14:47:08] * furrywolf keeps waiting
[14:47:18] <SpeedEvil> tiwake: indutor
[14:47:32] <furrywolf> inductor :)
[14:47:34] <CaptHindsight> yeah just a white screen and spinning blue circle on right for me
[14:47:41] <tiwake> SpeedEvil: so it should have very little resistance
[14:47:46] <SpeedEvil> yes
[14:47:51] <tiwake> ok
[14:47:54] <SpeedEvil> 'L40' is a clue
[14:47:59] <SpeedEvil> L = inductor
[14:48:03] <tiwake> didnt know that
[14:48:10] <CaptHindsight> hopefully
[14:48:16] <furrywolf> L is also the standard symbol for inductors, like R is resistors, Q transistors, C capacitors
[14:48:38] <tiwake> its L401, the 1 is hiding... heh
[14:49:02] <tiwake> well, I'm not seeing anything obviously wrong with this :-/
[14:49:16] <ssi> L401 is just the desginator
[14:49:54] * furrywolf wonders what "this" is and in what way it doesn't work
[14:51:12] <tiwake> Toshiba FWO1165F-1
[14:52:50] <furrywolf> that doesn't find much googling. only thing that sounds like a product is a CT scanner... which isn't the type of thing you want irc people fixing for you. :P
[14:53:46] <tiwake> hmm
[14:53:55] <tiwake> well, thats the part number on the board
[14:54:07] <tiwake> its a CRT screen
[14:54:32] <furrywolf> not worth fixing. :P
[14:54:34] <furrywolf> symptoms?
[14:55:20] <tiwake> blowing a fuse
[14:55:25] <furrywolf> check HOT
[14:55:33] <tiwake> ..?
[14:55:38] <archivist> use a meter look for the short
[14:55:41] <furrywolf> horizontal output transistor
[14:55:52] <tiwake> what is that?
[14:56:08] <ssi> the transistor driving the horizontal plates of the tube
[14:56:25] <archivist> the transistor next to the large coil for EHT
[14:56:48] <furrywolf> http://www.repairfaq.org/samnew/tvfaq.htm read
[14:58:03] <furrywolf> if you can't find a schematic for your exact product, see if you can find a schematic of anything that looks similar from around the same era. (assuming you get to the troubleshooting stage where you need one)
[14:59:03] <archivist> any old monitor may work
[14:59:51] <archivist> depending on signal type composite/ega/vga/something else
[15:00:06] <tiwake> https://www.dropbox.com/s/cn8nfikobws5l37/20150909_003.jpg?dl=0
[15:00:14] <tiwake> archivist: nope
[15:00:57] <tiwake> archivist: its non-standard voltages, as far as I can tell... hooked the signals up to an oscilloscope
[15:01:03] <tiwake> (yesterday)
[15:01:29] <furrywolf> voltage isn't as important as what the signals are...
[15:01:36] <furrywolf> RGBHV? composite?
[15:01:42] <tiwake> it is important
[15:01:53] <furrywolf> please upload it to something other than dropbox
[15:01:56] <furrywolf> dropbox really fucking sucks
[15:02:03] <CaptHindsight> can you replace it with a new LCD monitor?
[15:02:12] <furrywolf> or paste https://photos-1.dropbox.com/t/2/AABw8wtFL_H_6pfd8FCHvZ6Jr6SJ6MoBa8A0943bNXWKmg/12/119092607/jpeg/32x32/1/1441832400/0/2/20150909_003.jpg/CP_q5DggASACIAMgBCAFIAYgBygB/s3H1hExv586LmEtxM8-I6n9uouOh9N1sg9dIpy-v9bM?size_mode=5 instead. :)
[15:02:14] <tiwake> I'd put it on my server, but I cant upload to my server unless I am home
[15:02:19] <archivist> furrywolf, change the url to https://www.dropbox.com/s/cn8nfikobws5l37/20150909_003.jpg?dl=1
[15:02:22] <CaptHindsight> try changing the trailing 0 to a 1
[15:02:31] <archivist> then you can see the image
[15:02:39] <furrywolf> check the transistor on the big heatsink
[15:02:51] <tiwake> how do you check a transistor?
[15:03:27] <archivist> tiwake, mostlikel separate sync and video, (ega/vga is that)
[15:03:35] <furrywolf> well, for a start, measure the resistance between each pair of legs and see if any read 0 ohms.
[15:03:45] <archivist> some were 5 v signals
[15:03:59] <_methods> did you check the fuse lol
[15:03:59] <furrywolf> I see a plug with red, green, blue, and yellow wires. that sounds like RGB and combined sync...
[15:04:12] <furrywolf> _methods: <tiwake> blowing a fuse
[15:04:13] <CaptHindsight> https://www.youtube.com/watch?v=EpvGVeTjvws How to test a Bipolar Junction Transistor Using a Digital Multimeter
[15:04:16] <archivist> the display has a type number google that (unreadable)
[15:04:47] <furrywolf> what voltage/signals did your 'scope show going to it?
[15:04:51] <tiwake> Fanuc's part number is A61L-0001-0093
[15:05:16] <archivist> no the toshiba display type
[15:05:18] <furrywolf> oh, that's the yoke plug, isn't it? I was trying to figure out where the wires go. /me kicks self.
[15:05:45] <CaptHindsight> https://www.youtube.com/watch?v=M4tTiEqQllA Testing of Bipolar Transistors and Diodes, this video is fun since it's been dubbed
[15:05:55] <furrywolf> is it color or monochrome?
[15:06:05] <tiwake> furrywolf: for RGB it was somethig like 3.5 volts
[15:06:06] <archivist> rgb wire!
[15:06:08] <tiwake> erm
[15:06:13] <CaptHindsight> like watching a poorly dubbed kungfu film
[15:06:15] <tiwake> 2.5 volts for H-sync and Vsync
[15:06:17] <tiwake> al;sdfh
[15:06:19] <tiwake> 3.5
[15:06:20] <tiwake> w/e
[15:06:48] <furrywolf> that doesn't sound too odd.
[15:07:00] <tiwake> RGB was 1.2 volts
[15:07:06] <tiwake> give or take a little
[15:07:27] <tiwake> for standard VGA its 0.7 volts to peak
[15:07:31] <archivist> kludge a vga multisync
[15:07:55] <archivist> I bet you were testing opencircuit
[15:08:17] <ssi> yeah they need to be terminated properly
[15:08:21] <archivist> add the monitor load and it will drop
[15:08:22] <ssi> I think it's 75 ohms?
[15:08:32] <archivist> should be 75
[15:10:26] <furrywolf> what shape were the sync signals?
[15:11:20] <furrywolf> square or sawtooth, that is?
[15:11:29] <ssi> tiwake: what scope are you using?
[15:12:04] <CaptHindsight> http://martin.hinner.info/vga/An1-2.jpg did it look anything like this?
[15:12:22] <ssi> CaptHindsight: that looks more like ntsc
[15:12:55] <CaptHindsight> no colorburst, so closer to RS170
[15:13:07] <ssi> vga has independent sync signals
[15:13:11] <ssi> more like this
[15:13:12] <ssi> http://www.xess.com/static/media/uploads/blog/devbisme/2011-06-11/app001_2.png
[15:13:18] <furrywolf> since he has discrete rgb hsync vsync, I'm guessing no, it looked nothing like that. :P
[15:13:27] <PetefromTn_> Hoohah
[15:13:39] * furrywolf wants to know if the sync was square or sawtooth before analyzing further
[15:14:06] <archivist> and inverted or sensible
[15:14:17] <ssi> also a cheap pocket scope or pc-based scope probably won't be fast enough to capture vga
[15:14:17] <CaptHindsight> ssi: do you have a link to HDMI signals?
[15:14:37] <furrywolf> vga has square sync pulses, so if they're sawtooth, it's not vga.
[15:14:50] <ssi> I know nothing about hdmi
[15:15:05] <furrywolf> I suspect the HOT is what's on the big heatsink, and that would be the first place I'd check for fuse blowing.
[15:15:43] <archivist> it it blows quick there will be no hot
[15:15:48] <archivist> if
[15:15:56] <furrywolf> ?
[15:16:03] <ssi> lol
[15:16:07] <ssi> HOT != hot
[15:16:26] <CaptHindsight> B+ :)
[15:17:04] <ssi> B+ is archaic
[15:17:15] <archivist> tooooobs era
[15:17:24] <ssi> exactly
[15:17:40] <ssi> from when high tension was a battery instead of a transformer :P
[15:18:19] <archivist> early transformer stuff still called it B+
[15:18:21] <PCW> and you know we cant have archaic and eat it too
[15:18:32] <ssi> they still call it B+ in lots of tube designs with transformer power supplies
[15:18:32] <archivist> groan
[15:18:36] <ssi> but it's still archaic :D
[15:18:54] <ssi> most of the with it happenin cats call it HT+ nowadays
[15:19:07] <CaptHindsight> archaic, was common into the 80's :)
[15:19:15] <ssi> CaptHindsight: yeah like fortran :D
[15:19:57] <ssi> poor tiwake is not helped in any way by this frivolity
[15:20:32] <archivist> he still has not said the type number on the side of the chassis
[15:21:49] <CaptHindsight> I lost interest when it wasn't a CT anymore
[15:22:02] <ssi> CT?
[15:22:33] <CaptHindsight> CT scanner
[15:22:41] <ssi> when was it a CT scanner?
[15:22:59] <CaptHindsight> comes up in the Google search
[15:23:04] <ssi> oh right
[15:23:16] <ssi> diy CT scanners are a thing
[15:23:28] <tiwake> what?
[15:23:37] <tiwake> sorry, I had to step away from the computer
[15:23:42] <tiwake> :-/
[15:24:06] <ssi> http://blog.ponoko.com/2014/04/18/open-source-laser-cut-ct-scanner/
[15:24:07] <ssi> lol
[15:24:07] <CaptHindsight> ignore just about everything discussed when you were away
[15:24:10] <ssi> they're getting better
[15:24:59] <tiwake> ssi: I used an oscilloscope from a retired electrical engineer... no idea what kind it was, but it was CRT based
[15:25:09] <ssi> tiwake: bandwidth is important
[15:25:12] <XXCoder> did you guys know CAT scan was answer to math question "can we do line ingeration on magnetic field lines?"
[15:25:18] <CaptHindsight> ssi: makes sense, then you use this next http://www.opensurgery.net/
[15:25:18] <ssi> need at least a 50MHz scope for VGA
[15:25:23] <XXCoder> well answer was yes and it was useful.
[15:25:27] <tiwake> no idea
[15:25:32] <ssi> but if you're using a real scope then you're probably fin ethere
[15:25:41] <ssi> CaptHindsight: I'm down
[15:25:57] <tiwake> it went down to something like 1 or 2 microseconds
[15:26:02] <archivist> http://www.ebay.com/itm/1PC-Liquid-Crystal-Display-LCD-Compatible-with-All-CRT-Fanuc-A61L-0001-0093-NEW-/121735087678
[15:26:03] <ssi> CaptHindsight: friend of mine does repos on the side, and he recently reposessed a tattoo removal laser machine
[15:26:03] <tiwake> maybe further
[15:26:06] <ssi> I kinda want to play with it
[15:26:56] <CaptHindsight> ssi: how does he do that? Wait until it's parked outside?
[15:27:07] <ssi> tiwake: you'd need to go further... 25mhz is 40ns period
[15:27:13] <ssi> CaptHindsight: I guess!
[15:27:17] <ssi> he repos all kinds of shit
[15:27:28] <ssi> bouncy castles and restaurant stoves and weird stuff
[15:29:09] <tiwake> ssi: donno
[15:29:20] <tiwake> it probably went way down there
[15:29:53] <CaptHindsight> picturing a stove being pushed down the street with pans and flame still going
[15:29:54] <ssi> I would suggest you take another stab at scoping out the vga lines, take some pictures of the waveforms and put them on dropbox to make furrywolf mad
[15:30:15] <ssi> getting an idea of the shape of the signals will help get an idea of what the video standard is
[15:30:31] <ssi> CaptHindsight: this opensurgery nonsense is awesome
[15:30:40] <ssi> super makery, but up my alley :D
[15:31:48] <ssi> "Although I wouldn’t recommend to attempt surgery with it just yet, after five months of iteration it does in fact move."
[15:31:53] <ssi> wow only five months to get motion?
[15:31:55] <ssi> alert the press
[15:32:05] <tiwake> hmm
[15:32:15] <tiwake> I'd have to borrow the oscilloscope again
[15:32:46] <CaptHindsight> the wood grain hacky CT scanner was nice, I was only let down by the last pic not being a scan of the kitten
[15:32:57] <ssi> yeah and his setup is waaaaay too low res
[15:33:12] <ssi> there's a better one out there with a guy that used a big xray tube from ebay, a phosphor screen, and a dslr
[15:33:20] <ssi> with an arduino controlled turntable and shutter
[15:33:30] <ssi> and some perspective correction plus the CT integration
[15:33:55] <ssi> wasn't a cute little wood rotating deal, but it actually created some high res surprisingly good images
[15:34:03] <CaptHindsight> the laughing made my headache go away, now it's coming back
[15:34:37] <XXCoder> doh the stuff about math I menioned applies to MRI not CAT
[15:35:08] <ssi> XXCoder: yea CT is about interpolating voxels from multiple 2d images across different planes
[15:35:21] <XXCoder> yeah
[15:36:00] <CaptHindsight> http://www.opensurgery.net/img/Opensurgery_Domestic%20sterilization.jpg better caption: half baked designs
[15:36:08] <ssi> :D
[15:36:16] <_methods> open surgery lol
[15:36:42] <_methods> make magazine covers how to do an diy exploratory laparotomy
[15:37:01] <_methods> with a 3d printer and a kiddie pool
[15:37:05] <XXCoder> well they do have noble mission
[15:37:08] <ssi> _methods: I can't find that article
[15:38:05] <_methods> lol
[15:38:26] <CaptHindsight> _methods: is the pool to contain all the blood?
[15:38:28] <tiwake> ssi: not sure how much good that would do... I'm not exactly skilled with using an oscilloscope.. yesterday was my first time using one
[15:38:33] <ssi> http://www.opposingviews.com/i/society/veterinarian-kills-wife-after-performing-diy-liposuction-sends-body-pet-crematorium
[15:38:33] <_methods> i think they had to take it off the shelves because of all the nyc hipster deaths
[15:38:55] <chris_99> the CT thing looks pretty interesting
[15:39:47] <Sync> yeah
[15:39:54] <Sync> but he needs a proper xray source
[15:39:55] <XXCoder> jeez
[15:39:58] <XXCoder> vet != doctor
[15:40:09] <chris_99> i saw a tiny x-ray emmitter recently
[15:40:09] <ssi> XXCoder: semantics
[15:40:27] <ssi> chris_99: for the ultimate DIY bootstrappery, make your own!
[15:40:40] <chris_99> http://www.amptek.com/products/cool-x-pyroelectric-x-ray-generator/
[15:40:41] <ssi> https://www.youtube.com/watch?v=-0G4-JicCIw
[15:40:49] <chris_99> they weren't very helpful when i emailed them
[15:40:49] <chris_99> though
[15:40:53] <CaptHindsight> I don't want to be buried in a pet cemetery
[15:41:23] <XXCoder> reminds me of that show where guy buried cat in one and it come back
[15:41:33] <XXCoder> and he tried it on people and they also went evil
[15:42:02] <CaptHindsight> from the novel Pet Cemetery
[15:42:13] <ssi> pet sematary
[15:42:34] <Sync> I still need to get an xray source for my diffractometer
[15:42:40] <CaptHindsight> that to :)
[15:42:40] <ssi> Sync: https://www.youtube.com/watch?v=-0G4-JicCIw
[15:42:43] <roycroft> busy day! i've just spent four hours burying the cat!
[15:42:45] <ssi> get to it
[15:43:12] <roycroft> it wouldn't keep still, wriggling and howling its head off
[15:43:30] <Sync> ssi: too much hassle
[15:43:40] <ssi> lol that's the fun of it
[15:44:01] <Sync> I'd like to use it and not mess around with it until it works
[15:45:39] <Sync> and making a reliable xray source is annoying
[15:46:10] <XXCoder> can always use clear tape lol
[15:46:15] <Sync> I have done my fair share of vacuum engineering to realize it is not worth it
[15:46:20] <XXCoder> need vacuum though lol
[15:46:34] <ssi> I'm sure it's not worth it
[15:47:15] <Sync> that's fairly easy tho XXCoder
[15:47:30] <XXCoder> not a realiable source of xray im sure
[15:49:07] <Sync> I unfortunately got outbid on a kevex microfocus tube :/
[15:49:30] <XXCoder> too bad there is no led diode that emits xray
[15:49:44] <XXCoder> oh im wrong
[15:50:45] <XXCoder> no, I'm right there is no such thing
[15:52:53] <CaptHindsight> XXCoder: http://www.amptek.com/products/cool-x-pyroelectric-x-ray-generator/ like this link that chris_99 posted?
[15:53:04] <furrywolf> tiwake: were the sync waveforms square or sawtooth? did you test the transistor on the big heatsink?
[15:55:25] <CaptHindsight> http://www.amptek.com/products/mini-x-oem-x-ray-tube/ not too big, but a 120 deg cone
[15:56:00] <XXCoder> CaptHindsight: interesting
[15:56:47] <tiwake> furrywolf: sync waves were pretty darn square
[15:56:53] <CaptHindsight> http://www.aetjapan.com/english/hardware_detail.php?micromini_xray_source
[15:57:38] <CaptHindsight> http://www.newtonscientificinc.com/miniature-x-ray-tube-sources/
[15:58:18] <chris_99> i wonder how expensive they are
[15:59:40] <tiwake> furrywolf: which heatsink? the smaller one is just a transistor, the other one is a chip of some sort, not a single transistor
[16:00:41] <tiwake> the smaller heatsink with a single transistor thing is labeled Q402
[16:00:41] <furrywolf> square sounds like VGA, then.
[16:00:50] <furrywolf> test the one with three legs. :P
[16:00:54] <tiwake> what does Q mean?
[16:00:59] <ssi> transistor
[16:01:22] <tiwake> hmm
[16:01:31] <CaptHindsight> http://moxtek.com/xray-product/end-window-cabled-x-ray-sources/
[16:02:31] <CaptHindsight> I've had one on running all day on my desk and I still don't see any x-rays coming out of it :)
[16:02:44] <tiwake> I'd have to take it out to test it
[16:02:47] <ssi> CaptHindsight: I had that problem with co2 lasers
[16:02:57] <furrywolf> do a quick in-circuit test.
[16:03:07] <furrywolf> see if any pair of legs (test three times) measures 0 ohms resistance.
[16:04:26] <tiwake> one set does
[16:04:46] <tiwake> emitter to base
[16:05:03] <tiwake> the three legs on the board have a letter next to the solder joints
[16:05:06] <tiwake> CEB
[16:05:12] <furrywolf> OK, so you'll need to test it out of the board.
[16:05:17] <furrywolf> There's a very good chance it's toasted.
[16:05:30] <furrywolf> Desolder it (carefully!) and measure again.
[16:06:25] <furrywolf> I'd wager that's the HOT. Them shorting is a very common failure. That's why I said to check the HOT as soon as you said it was blowing fuses. :)
[16:06:47] <furrywolf> (horizontal output transistor)
[16:07:17] <tiwake> alright, lets try pulling it out
[16:07:19] <ssi> tiwake: before you desolder it
[16:07:26] <ssi> do you have a diode test mode on your meter?
[16:07:46] <furrywolf> If it measures shorted after you desolder it, order a new one, and test it. It might work, or it might instantly fry again. If it fries again, then you have other damaged components that are frying it.
[16:07:55] <tiwake> at 2k ohm resistance measure thing, it has a diode label next to it
[16:08:02] <furrywolf> ssi: if it's measuring 0 ohms on an ohms scale, a diode check scale isn't going to tell him anymore more useful.
[16:08:05] <CaptHindsight> if emitter to base and base to emitter are ZERO it's toast and start looking for the replacement
[16:08:28] <tiwake> but yes, I was using that mode
[16:08:32] <furrywolf> ohms scales are usually less than a diode junction output voltage
[16:08:49] <XXCoder> https://youtu.be/6BBx8BwLhqg
[16:08:52] <XXCoder> fun with mri
[16:09:45] <furrywolf> desolder it and test it again... there's guides for how to test transistors. they should never measure 0 in any direction, however.
[16:10:07] <furrywolf> I need to eat and deal with lawyers... I'll check back tonight and see what you found out. :)
[16:10:08] <furrywolf> bbl
[16:10:24] <XXCoder> dont let laywers bite furrywolf
[16:10:34] <CaptHindsight> http://www.ebay.com/itm/North-American-Imaging-PX1432-ES-X-Ray-Tube-50060599-/331547789236 is a medial device and needs a license
[16:10:49] <CaptHindsight> the bare tube itself does not
[16:11:27] <XXCoder> ton of pull from mri on chair ow
[16:11:38] <chris_99> do you need a licence if you're not using it for medical purposes
[16:12:32] <CaptHindsight> chris_99: not sure, but I think if it's a medial device and you want to use it to dig for gold the seller still wants to see a license
[16:12:50] <chris_99> ah heh
[16:13:39] <CaptHindsight> so it's easier to buy the hazardous parts vs an assembly
[16:14:55] <CaptHindsight> http://www.ebay.com/itm/Gendex-Dental-X-ray-Tube-Head-Tubehead-for-GX-Pan-Panoramic-Xray-/191647204356 but this seller doesn't seem to care or mention it
[16:15:43] <CaptHindsight> sorry it's in the disclaimer
[16:16:01] <Sync> there are enough of those gendex heads around to be had without a license
[16:16:25] <Sync> although you still need a license to run them
[16:16:59] <tiwake> fudge
[16:17:04] <tiwake> I cant find my wirewick
[16:17:21] <tiwake> desoldering will be next to impossible without it
[16:17:34] <CaptHindsight> http://www.ebay.com/itm/Complete-Belmont-065-Dental-Intraoral-X-Ray-Head-Tube-Arm-XRAY-Controller/111748586488 with controller $269
[16:18:34] <CaptHindsight> tiwake: try heating all 3 legs at the same time
[16:18:54] <tiwake> pff
[16:18:57] <ssi> worst case you could cut the legs of the transistor and desolder the left over pins one at a time
[16:18:58] <tiwake> that wont happen
[16:19:08] <ssi> you'll have to replace it even if it's good in that case
[16:19:18] <tiwake> ssi: cant do that with the heatsink and other components in the way
[16:19:21] <ssi> just be careful not to overheat the pcb and lift the pads
[16:19:22] <Sync> the controller is pretty useless
[16:19:40] <ssi> tiwake: LOVE WILL FIND A WAY
[16:20:07] <malcom2073> Is that what causes lifted pads, too hot?
[16:20:18] <malcom2073> I've lifted a few pads before, wasn't sure why
[16:20:30] <Sync> heat and stress
[16:20:34] <Sync> they are just glued on
[16:20:43] <malcom2073> Too much pulling not enough heat, too much heat not enough pulling, gotta get it just right I guess heh
[16:22:31] <ssi> yeah pretty much
[16:22:37] <ssi> but heat will delaminate traces
[16:22:41] <ssi> including pads and vias
[16:23:21] <XXCoder> in least we dont have chips slowly unseating anymore lol (in most cases)
[16:23:25] <XXCoder> ye olde days lol
[16:23:41] <ssi> no, now we just have tin whiskers shorting BGAs
[16:24:35] <CaptHindsight> thats what wire wrap wire is for, it was never intended for wire wrapping :)
[16:25:02] <ssi> what, fixing lifted traces?
[16:25:16] <PCW> A common cause of delamination is pressing on the pad with the iron tip
[16:25:37] <Sync> pressing is just fine but not rubbing
[16:25:48] <CaptHindsight> all types of pcb repairs, it's like the duck tape of the pcb world
[16:25:51] <PCW> not true
[16:25:58] <CaptHindsight> duct even
[16:26:07] <ssi> best way to ruin your board is to try to heat up a bunch of pins at once and yank on the part
[16:26:08] <XXCoder> tin is weird stuff
[16:26:19] <XXCoder> zinc is weirder
[16:26:22] <PCW> pressing will stretch the copper and dimple the board
[16:26:31] <PCW> = delamination
[16:26:47] <PCW> very light touch is needed
[16:26:49] <Sync> I don't know how hard you are able to press with your iron but a bit of pressure is just fine
[16:27:09] <PCW> nope
[16:28:13] <PCW> the epoxy-glass is very soft at soldering temperatures
[16:28:44] <PCW> you do not want to stretch the copper (thats only say 1.3 mills thick)
[16:29:07] <PCW> a few ounces will cause damage
[16:29:22] <Sync> nope :)
[16:29:42] <Sync> I have done thousands of joints pressing on the pad and never delaminated one
[16:29:54] <ssi> "done"?
[16:29:59] <PCW> well I sure would not let you work on our cards :-)
[16:30:29] <ssi> you can get away with soldering like that, but desoldering takes a lot more heat and mechanical manipulation, and you WILL pull the pads out that way
[16:31:13] <PCW> you have to be very careful especially on older equipment (older PCB material is not as tough)
[16:31:41] <Deejay> gn8
[16:31:54] <cradek> that, I've certainly noticed
[16:32:25] <cradek> if it's old stuff with hand-drawn traces, they seem to just fly off the board
[16:32:42] <cradek> PCW: I had never noticed pressure does it, but I'll watch for that now
[16:32:42] <ssi> especially without soldermask
[16:32:51] <ssi> there's not much holding the copper down, but soldermask certainly helps
[16:33:30] <cradek> fortunately that old stuff is often single-sided so pulling parts out doesn't lift the pads
[16:34:08] <Sync> ssi: I usually desolder with a desoldering iron
[16:34:12] <PCW> the newer PCB stuff thats ROHS solder compatible is really hard to heat damage
[16:34:13] <cradek> (I agree about chopping up the part and then doing one lead at a time)
[16:34:48] <PCW> yeah the less stress on the PCB the better
[16:35:24] <PCW> preheating with a hot air gun is good also
[16:35:41] <CaptHindsight> I recall my very first attempt at desoldering a pcb component with my brand new Weller 150W Pistol :)
[16:35:55] <ssi> CaptHindsight: ha I've been there
[16:36:03] <ssi> with the trigger and light on front
[16:36:08] <CaptHindsight> yup
[16:36:10] <zeeshan> hi
[16:36:12] <ssi> pull the trigger, watch the pcb blacken before your very eyes
[16:36:15] <ssi> zeeshan: THERE YOU ARE
[16:36:22] <ssi> get a better job where you can IRC at work nubcake
[16:36:29] <zeeshan> lol
[16:36:35] <zeeshan> dude im gonna be super busy
[16:36:37] <ssi> :P
[16:36:38] <zeeshan> for the next couple months now
[16:36:39] <cradek> butane torch can do a decent job of desoldering a bunch of nearby pads at once
[16:36:44] <zeeshan> i got a huge order for my home shop
[16:36:55] <CaptHindsight> ssi: how many tips do you bend trying to push components through the pcb?
[16:37:02] <cradek> "nubcake"?
[16:37:12] <zeeshan> hes calling me a noob
[16:37:24] <zeeshan> but he's also calling me flamboyant
[16:37:24] <ssi> no I called you a nubcake
[16:37:27] <zeeshan> :P
[16:37:43] <ssi> a flamboyant inexperienced dessert
[16:37:44] <zeeshan> i know pete has a cnc mill
[16:37:50] <malcom2073> Lol
[16:37:50] <zeeshan> anyone else here can make aluminum parts?
[16:38:02] <zeeshan> maybe i can split this job up
[16:38:05] <cradek> never heard of "aluminum"
[16:38:07] <malcom2073> Probably a lot of people :P
[16:38:16] <cradek> (yeah probably all of us)
[16:38:35] <zeeshan> its a large quantity order, the cost per piece isn't much
[16:38:41] <ssi> zeeshan: i'm busy myself, trying to get studied up to take these tests
[16:38:41] <zeeshan> cost = pay
[16:39:16] <CaptHindsight> I think Andy only works on "Aluminium" parts :)
[16:39:37] <andypugh> Pete seems most likely to want the work. I think a lot of us would rather buy more hobby-time
[16:39:46] <CaptHindsight> same for Archivist
[16:39:53] <malcom2073> Heh
[16:40:02] <zeeshan> andypugh: im starting to feel like that now
[16:40:09] <zeeshan> 7-3:30 full time job
[16:40:13] <malcom2073> The joys of turning a hobby into a job :)
[16:40:19] <zeeshan> then another 5 hours home shop will be my schedule
[16:40:21] <zeeshan> for the next 6 months
[16:40:23] <zeeshan> + school
[16:40:40] <zeeshan> but im young, and money is more important to me right now :P
[16:40:41] <CaptHindsight> zeeshan: do the parts require any drilling or milling?
[16:40:47] <zeeshan> all milling parts
[16:40:47] <andypugh> I think I would rather be poor. But I am lucky enough that that isn’t the decision.
[16:41:09] <zeeshan> i owe about 190,000 on my house mortgage
[16:41:16] <zeeshan> my goal is to pay it off in 6 months
[16:41:19] <malcom2073> I'd rather neither poor nor busy
[16:41:29] <zeeshan> and never have to worry about this shit again :P
[16:41:50] <andypugh> (Actually work is so horribly quiet at the moment that I get most of my hobby stuff done there too. My current car is launched, the next protoypes come in January, I really have practically nothing to be doing)
[16:42:04] <CaptHindsight> shhh
[16:42:09] <zeeshan> lol
[16:42:24] <andypugh> No, I have told my boss exactly that, he is bored too.
[16:42:37] <CaptHindsight> nice work if you can get it
[16:43:11] <CaptHindsight> andypugh: are you buried when it's busy?
[16:43:19] <andypugh> Yes. :-)
[16:43:50] <CaptHindsight> map this ECU by next Tuesday :)
[16:45:28] <andypugh> “Becuae that was always the schedule, and it isn’t our fault that the hardware was 6 monhs late"
[16:45:46] <CaptHindsight> oh great
[16:48:30] <Sync> haha yeah car dev schedules are fun
[16:48:54] <Sync> we did some stuff for the infotainment in GM cars
[16:50:07] <Sync> spec was not finished until we were close to delivery
[16:50:41] <malcom2073> Heh, I work for a military contractor, specs aren't finished even after delivery :-D
[16:50:51] <zeeshan> :D
[16:50:55] <Sync> sounds typical
[16:51:32] <Sync> we had to call in a certifying notary to say that our final test station put the green light on
[16:51:39] <Sync> for some mil stuff
[16:51:54] <Sync> super retarded as it was only a prototype run
[16:52:05] <ganzuul> \o/
[16:52:26] <ganzuul> I think I'm ready to place my order for a lathe.
[16:52:45] <zeeshan> ganzuul: hopefully you dont get dicked around like i currently am
[16:52:57] <CaptHindsight> ganzuul: post the link and we'll talk you out of it if you want or need that :)
[16:53:00] <malcom2073> zeeshan: You're still getting dicked around?
[16:53:04] <zeeshan> yep
[16:53:07] <zeeshan> everyday he says
[16:53:09] <malcom2073> Getting dicked around for more than a day is nobodys fault but yours :P
[16:53:11] <zeeshan> "vp of company wasn't in"
[16:53:17] <zeeshan> well its a good deal for the lathe
[16:53:19] <zeeshan> and my heart's on it
[16:53:25] <malcom2073> Heh, I'm tellin ya, run.
[16:53:26] <ganzuul> CaptHindsight: I don't know if I do!
[16:53:29] <ganzuul> hmmm
[16:53:34] <zeeshan> sometimes you just gotta deal with it
[16:53:37] <malcom2073> What makes you think the lathe itself will be any less headache than the guys you're buying it from? :P
[16:53:46] <zeeshan> cause it's in running condition
[16:53:50] <zeeshan> and they will show me that
[16:54:01] <ganzuul> I'll make a page, since the store doesn't have the wishlist sharing thing
[16:54:05] <CaptHindsight> zeeshan: what if it's cursed?
[16:54:14] <zeeshan> i dont believ ein curses
[16:54:26] <CaptHindsight> that what they all say :)
[16:54:26] <zeeshan> honestlky since i sold my lathe
[16:54:30] <malcom2073> What if it's broken in bad ways, but they know how to work aroudn them for demonstration purposes? :P
[16:54:31] <zeeshan> i could probably buy both lathes
[16:54:32] <zeeshan> that he wants to sell
[16:54:39] <zeeshan> but i have no room to put the other one while i await to see it
[16:54:41] <zeeshan> *sell it
[16:54:50] <ganzuul> lol, a cursed lathe
[16:54:52] <zeeshan> malcom2073: i'm not a dumbass..
[16:54:59] <zeeshan> i've been around machinery long enough
[16:55:05] <malcom2073> zeeshan: You have to assume the seller is smarter than you
[16:55:12] <ganzuul> +2 to str, -2 to int
[16:56:43] <zeeshan> malcom2073: i told him that if he's not back to me by friday, forget the deal
[16:56:46] <Sync> just store it in your driveway zeeshan
[16:56:47] <zeeshan> was pretty firm on that
[16:56:51] <malcom2073> Under a tarp
[16:58:53] <Sync> or just run it under the tarp
[16:59:06] <Sync> just make sure that no coolant freezes in it
[17:15:15] <zeeshan> man this cold needs to go away
[17:15:20] <zeeshan> die cold virus!
[17:16:15] <Tom_itx> it's out to get you first
[17:16:41] <Tom_itx> stop workin so damn much... i need someone here to heckle
[17:19:21] <zeeshan> haha
[17:19:38] <zeeshan> this time of the season
[17:19:45] <zeeshan> so crap for getting sick
[17:23:45] <ssi> zeeshan: http://www.playboy.com/articles/mechanical-engineering-student-wakes-up-and-realizes-he-drunkenly-designed?utm_source=fb&utm_medium=social&utm_content=humor&utm_campaign=engineerplane
[17:23:53] <ssi> WAS THAT YOU
[17:24:13] <zeeshan> i dont drink :P
[17:24:51] <ssi> no wonder you're so boring
[17:24:58] <malcom2073> " high speed plane that floats above water," Have you seen the ground effect planes?
[17:25:04] <zeeshan> my alcohol is machines
[17:25:05] <zeeshan> and engineering
[17:25:06] <zeeshan> mate
[17:25:07] <ssi> yes, Wing In Groundeffect
[17:25:08] <zeeshan> :D
[17:25:17] <ssi> the russians love that idea
[17:25:28] <ssi> but he's got some horrible looking keel with a propeller on it that presumably stays underwater
[17:25:32] <malcom2073> HEh
[17:25:39] <ssi> which isn't going to work at all
[17:26:10] <malcom2073> Are you seriously analyzing this guys drunken design?
[17:26:14] <ssi> YES
[17:26:21] <malcom2073> He's denying memory of it cause he knows it sucks :P
[17:29:23] <PetefromTn_> hey folks
[17:29:27] <ssi> hey pete
[17:29:34] <PetefromTn_> howsitgoin?
[17:29:39] <ssi> taking practice tests :P
[17:29:42] <ssi> Here are your Practice Exam Results for Aviation Mechanic General:
[17:29:42] <ssi> 54 question(s) answered correctly (90%) out of 60 questions asked.
[17:29:43] <ssi> You completed the practice session in 18 minutes (on time).
[17:29:44] <ssi> getting there
[17:29:44] <ssi> heh
[17:29:45] <PetefromTn_> ooh fun
[17:30:06] <ssi> 20% wasted effort! :D
[17:30:08] <PetefromTn_> nice that they have freaking practice tests for you to tkae
[17:30:09] <PetefromTn_> take
[17:30:16] <PetefromTn_> its funny
[17:30:30] <ssi> it's a small question bank too
[17:30:34] <PetefromTn_> I was offered ANOTHER part time job working with a friend of mine
[17:30:36] <ssi> most people pass these tests by memorizing the answers
[17:30:53] <PetefromTn_> and I went over there yesterday to speak with the owner
[17:31:20] <PetefromTn_> he was a really cool guy and they wanted me to run their CNC lathe and manual mill/lathe as well as the CNC mill occasionally
[17:31:39] <PetefromTn_> I would have been working with my friend too which would have been cool
[17:31:47] <PetefromTn_> but I turned it down today
[17:32:05] <ssi> why?
[17:32:08] <PetefromTn_> because I am kind of busy with my own parts picking up sales and making stuff for the race shop guys
[17:32:15] <ssi> gotcha
[17:32:26] <PetefromTn_> as well as the part time Tig welding work I am doing over there
[17:32:28] <zeeshan> PetefromTn_: PM
[17:32:37] <maZer`-> hi all
[17:32:54] <ssi> yes by all means zeeshan load him up with more crap to do :)
[17:34:28] <maZer`-> i know im in linuxcnc channel, but maybe someone got idea. I got TNC 155 Controller and i try to do a helix with g3
[17:34:43] <maZer`-> N55 G1 Y-35. Z-0.069 F1000
[17:34:43] <maZer`-> N60 G3 X-35. Y-25. Z-0.178 R10.
[17:35:11] <maZer`-> thats my code, but always after the g3 command the machine stops and tell me "ebene falsch definiert"
[17:36:32] <maZer`-> if i remove the z-0.178 that command works and he doing next line.
[17:38:25] <JT-Shop> zeeshan, if Pete makes your parts how are you going to smuggle them into Canada?
[17:38:40] <zeeshan> shipping
[17:39:10] <JT-Shop> they jack me so much on shipping to Canada it ain't funny
[17:45:15] <CaptHindsight> http://www.me.udel.edu/meeg447/98/serffiles/fall4-design-reviews/dr-ppt/dr-02.ppt "In search of perfect melons"
[17:47:06] <ganzuul> OKAY!
[17:47:08] <ganzuul> http://nya.dy.fi/static/lathe/arceurotrade.htm
[17:47:47] <ganzuul> By tossing out a bunch of stuff that were not absolutely essential I was able to add that hella-expensive milling attachement.
[17:48:12] <ganzuul> Figure I
[17:48:27] <ganzuul> I'll cut the tools I need with the carbide bit.
[17:48:44] <ganzuul> No ER32 collet or 4-jaw chuck.
[17:49:10] <ganzuul> I can get those later...
[17:49:24] <ganzuul> So that's my starter kit right there.
[17:49:36] <CaptHindsight> http://www.arceurotrade.co.uk/Catalogue/Machines-Accessories/Lathes/Model-C3-Mini-Lathe/Model-Super-C3-Mini-Lathe#Model-Super-C3-Mini-Lathe
[17:50:29] <CaptHindsight> i just got rid of a 12 x 36 lathe for about that price
[17:51:01] <ssi> I need to sell my cnc g0602
[17:52:08] <CaptHindsight> ssi: did you do the conversion?
[17:52:11] <ssi> yes
[17:52:23] <ganzuul> CaptHindsight: How much did it weight?
[17:52:48] <CaptHindsight> ganzuul: ~1200 lbs with the stand
[17:53:07] <tiwake> ssi: 0.5 nanoseconds
[17:53:23] <ssi> tiwake: the min timebase on the scope?
[17:53:27] <tiwake> yeah
[17:53:33] <ssi> yeah that's plenty good enough
[17:53:37] <tiwake> heh
[17:53:38] <ganzuul> That'd break our elevator 2 times.
[17:54:46] <CaptHindsight> ganzuul: are you interested in something used and cnc?
[17:56:06] <tiwake> ssi: its one of these http://www.testequipmentdepot.com/usedequipment/tektronix/oscilloscopes/465.htm?gclid=CPGSjPiA68cCFdcYgQodBqkFRA
[17:56:24] <ssi> ya classic scope
[17:57:06] <ganzuul> CaptHindsight: Yes, but nothing over 240kg...
[17:57:55] <CaptHindsight> ganzuul: what part of the world are you in?
[17:58:10] <ganzuul> Finland
[17:58:48] <andypugh> I am not sure I believe the spec of this motor. NEMA 34, 3.5” long. 830W
[17:59:05] <ssi> andypugh: 830W in, 200W out :P
[17:59:13] <CaptHindsight> heh
[17:59:47] <andypugh> http://ab.rockwellautomation.com/Motion-Control/TL-Series-Servo-Motors
[17:59:50] <CaptHindsight> with built in heater
[18:00:18] <andypugh> The surface temperature is allowed to be 110C, that’s one way to increase heat-flux
[18:00:57] <CaptHindsight> I use their linear servos
[18:01:26] <andypugh> Nice piece of kit, except I killed the encoder (I got it before the Mesa serial encoder stuff existed)
[18:01:42] <andypugh> So I am fitting a resolver that I had lying about.
[18:04:31] <PCW> I have a newer Yaskawa 400W newma23 motor and its just 3.5" long excluding the encoder so 830 for a nema34 that long is possible
[18:05:40] <CaptHindsight> I have found their docs and spec to be pretty accurate
[18:06:19] <CaptHindsight> and the prices to be higher than most but very reliable
[18:06:36] <CaptHindsight> the motors not the prices
[18:07:05] <PCW> Also power scales with RPM so you can get a lot more from 6000/7500 RPM motors power/size wise
[18:07:46] <CaptHindsight> does it spec the rated speed?
[18:08:10] <CaptHindsight> some are 8k rpm
[18:08:37] <andypugh> This is 50000rpm
[18:08:42] <andypugh> Sorry, 5000
[18:09:21] <andypugh> I will be using it for a lathe cross-slide, so it might be a bit faste than necessary. Not much room for reduction gear.
[18:09:26] <PCW> yeah 830W is reasonable
[18:09:52] <andypugh> (14mm motor shaft, only about 35mm of space at the end of the leasdscrew)
[18:10:25] <andypugh> I have another Reliance servo. That’s 1kW and the size of a shoe box!
[18:11:22] <zeeshan> are you sending it to me
[18:11:36] <andypugh> No, both have a home and a job.
[18:11:56] <CaptHindsight> zeeshan: I can send you shoe boxes :)
[18:12:40] <zeeshan> when will i score some free stuff from one of you guys?
[18:12:42] <zeeshan> :(
[18:13:03] <PCW> my Yaskawa NEMA23 400W motor has a 14MM shaft
[18:14:06] <CaptHindsight> ganzuul: that 10 x 22 like ssi has is about as big as you can go, unless to can take it apart
[18:14:21] <CaptHindsight> http://www.ebay.com/itm/G0602-Grizzly-10-x-22-Bench-Top-Metal-Lathe-/271904183239
[18:14:49] <andypugh> PCW: I have a couple of NEMA 23 servos with an 8mm shaft. I thought NEMA defined the shaft size?
[18:15:02] <andypugh> (and that it should be 10mm)
[18:15:22] <tiwake> andypugh: I thought NEMA defined the bolt hole pattern...
[18:15:40] <tiwake> not that I've read any documentation on it
[18:15:49] <ganzuul> !=O
[18:15:56] <andypugh> I am not 100% sure, I don’t live in the N of NEMA
[18:18:16] <CaptHindsight> ganzuul: too bad used machines are so hard to find there
[18:18:31] <ganzuul> ssi: where are you located?
[18:19:04] <CaptHindsight> he's USA, Georgia
[18:19:33] <ganzuul> ah... Well then taxes and shipping will eat up any benefit. :(
[18:19:49] <CaptHindsight> yeah, lots of old iron here
[18:20:26] <CaptHindsight> and shipping and taxes are probably similar even if you found it in the UK
[18:20:50] <ganzuul> No import tax within the EU.
[18:23:08] <ganzuul> fedex wants over 3k USD for shipping 432lbs here
[18:24:58] <zeeshan> from where to where ganzuul?
[18:25:05] <jthornton> cheaper to fetch it yourself and pay the baggage fees
[18:25:17] <ganzuul> Rome, georgia
[18:25:23] <ganzuul> to Turku, Finland
[18:25:30] <zeeshan> not bad
[18:25:39] <zeeshan> but i would look at ltl shipping
[18:25:41] <zeeshan> not fedex
[18:25:49] <zeeshan> they do ltl , but they are almost 4x the cost of a normal place
[18:26:01] <zeeshan> i did ltl of an engine from bc canada to hamilton ontario
[18:26:05] <zeeshan> it cost $480
[18:26:29] <andypugh> Buy a van. Sell it at the end of the job.
[18:26:37] <jthornton> but that is almost in the same country hey
[18:26:46] <kengu> close enough
[18:29:34] <zeeshan> jthornton: haha
[18:31:09] <CaptHindsight> ganzuul: the freight costs are also much lower from port to port vs door to door
[18:31:19] <CaptHindsight> usually 1/2
[18:32:32] <kengu> CaptHindsight: yes but the get it from port to door costs then the other half
[18:34:06] <CaptHindsight> kengu: but he might have a truck or friend with motorized skateboard
[18:35:04] <ganzuul> ...Auction? I though they'd just show standard rates with that LTL thing. >.<
[18:35:25] <ganzuul> CaptHindsight: oooh! That's interesting!
[18:39:46] <CaptHindsight> ganzuul: http://www.ebay.co.uk/itm/WARD-CNC-LATHE-WARD-CNC-CAPSTAN-LATHE-WARD-NO-7-LATHE-AUDIT-CNC-M268-36-BC-/331642747202?hash=item4d3772b942
[18:40:32] <andypugh> I think I would avoid Capstan lathes for CNC conversion to conventional lathes/
[18:41:30] <CaptHindsight> how are these http://www.ebay.co.uk/itm/Harrison-M350-x-1m-Centre-Lathe-/321850234487?
[18:42:20] <zeeshan> CaptHindsight: do you have any machines? :P
[18:42:41] <zeeshan> i never hear you talkin about your machines
[18:43:02] <ganzuul> CaptHindsight: "Used daily until recent replacement arrived "
[18:43:03] <zeeshan> don't be shy :P
[18:43:11] <ganzuul> So it is likely worn...
[18:43:29] <CaptHindsight> zeeshan: I build most of my equipment
[18:43:33] <ganzuul> That previous one looks like something out of 1950s sci-fi.
[18:43:37] <zeeshan> like what?
[18:45:27] <ganzuul> CaptHindsight: And it'd break our elevator 5 times over...
[18:45:28] <CaptHindsight> zeeshan: you've seen some of my retrofits
[18:45:47] <zeeshan> i remember a big mill
[18:45:53] <zeeshan> a long time ago you posted a pic
[18:46:00] <ganzuul> Haters gonna hate... I'ma just place an order for the 7x.
[18:46:48] <CaptHindsight> ganzuul: you're just in a tough to get to area for heavy objects
[18:47:30] <ganzuul> We have a port, but not a lot of shipments coming through.
[18:48:05] <ganzuul> Internal server error.
[18:48:13] <ganzuul> Wel...
[18:48:22] <ganzuul> Call me cheque blocked
[18:48:47] <CaptHindsight> zeeshan: when you could see the floor http://imagebin.ca/v/2F6aQJzkcazu
[18:48:51] <andypugh> ganzuul: We ship stuff to Turku all the time
[18:49:08] <andypugh> But I think they would notice if I tried to sneak a lathe in amongst all the cars
[18:49:20] <ganzuul> :o
[18:49:46] <ganzuul> That's kinda cool though.
[18:50:20] <cpresser> is there a way to clear the backplot in vismach?
[18:50:25] <andypugh> Truck to Harwich, boat to Turku, road to Rovaniemi
[18:50:49] <andypugh> cpresser: Probably :-)
[18:51:28] * cpresser needs to ask the right questions^^
[18:51:45] <andypugh> I was just checking the docs, but they don’t say
[18:52:59] <CaptHindsight> zeeshan: but I mostly build things like this http://imagebin.ca/v/2F6bfkexZtC3
[18:53:00] <ganzuul> andypugh: Rovaniemi? Are you sure? That's the city furthest North in Finland.
[18:53:15] <andypugh> Yes, that’s why we go there. It’s cold
[18:54:00] <ganzuul> andypugh: Oh, for testing!
[18:54:26] <andypugh> Yeah, we bring them back through Turku too
[18:55:03] <ganzuul> Cool. :)
[18:55:30] <zeeshan> CaptHindsight:
[18:55:35] <zeeshan> yuou should post more pics of your stuff
[18:55:38] <zeeshan> that looks impressive man
[18:55:52] <zeeshan> are those rails on a granite block?
[18:55:54] <zeeshan> for Z
[18:56:09] <CaptHindsight> zeeshan: most of my stuff is done under NDA
[18:56:14] <zeeshan> aw
[18:56:14] <zeeshan> :{
[18:56:58] <CaptHindsight> all linear or rotary servos, and yeah on granite
[18:57:09] <zeeshan> it seems like
[18:57:13] <zeeshan> all modern cnc machines use rails
[18:57:16] <zeeshan> on machined blocks
[18:57:31] <zeeshan> i guess its easier to maintain
[18:57:36] <zeeshan> and easier to achieve tolerances
[18:57:49] <zeeshan> you dont need to induction harden the base casting
[18:57:59] <CaptHindsight> dual linear servos one the bottom
[18:58:10] <zeeshan> nice
[18:58:26] <CaptHindsight> probably $70k in servos
[18:58:55] <CaptHindsight> the rotary for the trunnion was $18K
[18:59:00] <ganzuul> CaptHindsight: Is the structure aluminium?
[18:59:08] <zeeshan> big money :D
[18:59:26] <zeeshan> if i get this bid successful
[18:59:31] <zeeshan> I Will be a big boy too!!
[19:02:09] <CaptHindsight> zeeshan: building a new lathe next, all servos and air bearings
[19:03:06] <andypugh> cpresser: I don’t see a binding to clear the backplot: http://git.linuxcnc.org/gitweb?p=linuxcnc.git;a=blob;f=lib/python/rs274/OpenGLTk.py;h=a9834fb649fcf006df3e87d3b991759ea8fbbf65;hb=fdb8d52bfcf938c4553e68a5cf39b7b1cc76e71d#l149
[19:03:16] <zeeshan> nice
[19:04:26] <andypugh> CaptHindsight: Have you seen that one on Youtube? It’s rather nice. https://www.youtube.com/watch?v=sFrVdoOhu1Q
[19:04:38] <CaptHindsight> why I was asking about Linuxcnc and Dual-Pinion Electrical Preload
[19:04:52] <CaptHindsight> andypugh: yes
[19:05:14] <CaptHindsight> http://www.servotak.eu/products/custom-products/zero-backlash-rack-pinion-gearbox-systems
[19:05:32] <cpresser> andypugh: i checked the vismach source, couldnt find one either
[19:05:47] <cpresser> seems like another small thing I could try to patch
[19:05:50] <andypugh> That’s the source for the actual display widget
[19:06:05] <zeeshan> what determines what color the lines will be?
[19:06:07] <zeeshan> like for rapid
[19:06:27] <zeeshan> i came across an old fanuc controller
[19:06:29] <zeeshan> 11t i think
[19:06:33] <andypugh> We aren’t talking about Axis here
[19:06:44] <zeeshan> it was kinda cool, it had different colors for different tool paths
[19:06:47] <zeeshan> oh
[19:07:10] <andypugh> (Axis uses Gremlin, Gremlin might well use that same OpenGltk viewport though
[19:09:00] <ganzuul> CaptHindsight: So since they always eliminate backlash, they don't have to worry about the gearbox either. Clever. :)
[19:09:02] <zeeshan> http://www.pailsys.co.jp/image/m-kamu1.gif
[19:09:20] <zeeshan> looked similar to that
[19:09:22] <zeeshan> very pretty
[19:10:51] <andypugh> CaptHindsight: It looks trivial, simply a PID feeding back on motor current.
[19:11:44] <andypugh> CaptHindsight: for a simpler solution, use a double-helical rack and pinion, and spring-load it axially. Same effect. Cheaper.
[19:11:52] * Jymmm got a Machinery's Handbook for $5 today =)
[19:12:30] <CaptHindsight> andypugh: for a small lathe yeah
[19:12:38] <andypugh> (I invented that double-helical idea myself, but I am pretty sure I didn’t invent it first)
[19:12:40] <Tom_itx> Jymmm, what edition
[19:12:41] <Jymmm> Now maybe I'll understand metric fucking threads =)
[19:12:46] <maZer`GTi-> hm, can someone explain me on haidenhain how g13 the command H is working? :(
[19:13:04] <CaptHindsight> somebody asked about a printer for cylinders 7m long and 1.5m dia
[19:13:06] <Jymmm> Tom_itx: 22nd, 1987. But I doubt the math has changed much =)
[19:13:19] <roycroft> that one is a decent one
[19:13:20] <Tom_itx> just new stuff
[19:13:25] <roycroft> get a 1940'ish one as well
[19:13:26] <Tom_itx> mine is 25
[19:13:33] <andypugh> maZer`GTi-: What is G13 meant to do?
[19:13:42] <roycroft> the deal with machinery's handbook is this:
[19:13:49] <roycroft> it cannot change in size
[19:14:01] <roycroft> it always had to fit that drawer in machinist's tool boxes
[19:14:06] <Jymmm> roycroft: I look for OLD refernce books too. I have a 115yo Physics book
[19:14:07] <maZer`GTi-> g13 is the only way to drive helix with my control :(
[19:14:09] <roycroft> so when they add new stuff they have to remove stuff
[19:14:11] <Jymmm> roycroft: ah
[19:14:12] <_methods> g13 is polar interpolation
[19:14:15] <maZer`GTi-> yes
[19:14:16] <_methods> instead of cartesian
[19:14:20] <roycroft> so an old version is useful
[19:14:24] <roycroft> as is the most up-to-date version
[19:14:25] <Tom_itx> roycroft, make the font smaller :)
[19:14:31] <_methods> rarely used
[19:14:33] <roycroft> it's already almost unreadable
[19:14:38] <Tom_itx> yeah i know
[19:14:44] <andypugh> Jymmm: What’s to understand? The size is how big it is, the pitch is the thread pitch, the tapping size is the OD minus the pitch (also works with US threads, that last bit, but not proper threads with a 55 degree thread angle :-)
[19:14:48] <_methods> do you have some application that requries you to use g13?
[19:15:04] <Tom_itx> andypugh seems logical to a brit
[19:15:05] <roycroft> a 1987 edition is pretty good
[19:15:06] <maZer`GTi-> yes
[19:15:16] <roycroft> it's right before they started adding a bunch of cnc stuff
[19:15:16] <maZer`GTi-> i want to drive in helix to create just a hole :(
[19:15:25] <roycroft> so they hadn't ripped too much out yet
[19:15:27] <_methods> and you can't use g3 for that?
[19:15:28] <maZer`GTi-> my machine doesnt support z parameter on g2 or g3 command :(
[19:15:29] <Jymmm> andypugh: Say that again, this time without the Brit Speak ;)
[19:15:32] <_methods> ahhhh
[19:15:37] <CaptHindsight> andypugh: the big lathes do it electrically http://www.romiusa.com/heavy-duty-lathes/
[19:15:41] <_methods> but it will for g13?
[19:15:45] <roycroft> s/55/60
[19:15:46] <maZer`GTi-> the baddest thing, thats why i want to retrofit later to linuxcnc
[19:15:47] <roycroft> there
[19:15:51] <maZer`GTi-> yes _methods
[19:15:54] <roycroft> i translated to 'ericun for you
[19:15:59] <_methods> interesting
[19:16:14] <maZer`GTi-> but first i want to study the machine and testing and all. want to play with post processor and all. :D
[19:16:33] <Jymmm> roycroft: try again, just less hick this time.
[19:16:59] <andypugh> CaptHindsight: Monster lathe with a 10.4” LCD screen?
[19:17:06] <CaptHindsight> andypugh: looks like the transition from mechanical to electrical preload is ~5 meters
[19:17:39] <CaptHindsight> andypugh: yeah it should come with a 60" 4k monitor :)
[19:17:56] <andypugh> CaptHindsight: But do they do the mechanical preload the way I described?
[19:17:58] <_methods> i don't use g13 so i won't be much help on that one
[19:18:15] <_methods> you'll have to look at some guides for programming using polar interpolation
[19:18:40] <andypugh> LinuxCNC can use polar coordinates, but that’s not much help to you.
[19:19:56] <CaptHindsight> andypugh: I didn't notice any with the helical rack
[19:20:20] <andypugh> It needs to be double helical or it won’t work
[19:20:32] <CaptHindsight> might be a patent thing
[19:21:17] <andypugh> I don’t know for a fact that anyone has ever done it. It might actually be my own world-changing invention. But I just think it is too obvious for that to be true.

[19:23:04] <CaptHindsight> http://www.redex-andantex.com/p-en-871-%E2%80%A2-krpx-single-or-twindrive.html
[19:23:56] <maZer`GTi-> ok i think i have it
[19:24:00] <CaptHindsight> http://www.redex-andantex.com/more.php?id=334
[19:24:09] <_methods> maZer`GTi-: in the cnc programming handbook by peter smid he goes over polar interpolation very well
[19:24:14] <_methods> you might want to look at that
[19:24:40] <andypugh> CaptHindsight: Not the same thing at all
[19:24:42] <maZer`GTi-> ok but problem is my controlling unit is very very stupid :(
[19:25:45] <andypugh> CaptHindsight: Double-helical rack, single double-helical gear. Push the gear axially relative to the rack, and it touches both faces of the rack.
[19:26:16] <andypugh> The spring force is magnified by the helix angle into a preload.
[19:26:43] <maZer`GTi-> i read a lot of books but my maschine doesnt accept many things :(
[19:26:46] <CaptHindsight> I follow. I just posted what I found off the shelf
[19:27:04] <andypugh> Anyway, sleep beckons.
[19:28:22] <CaptHindsight> https://en.wikipedia.org/wiki/Herringbone_gear
[19:31:57] <ganzuul> Isn't herringbone just to eliminate axial forces?
[19:36:09] <malcom2073> iirc, they can be designed to be backlash reducing

[19:39:21] <ganzuul> https://www.youtube.com/watch?v=QAgSY52zdhg
[19:39:22] <ganzuul> Gear Types and characteristics
[19:42:20] <CaptHindsight> great pdf on several gears http://web.itu.edu.tr/temizv/VTDN/Gears.pdf
[19:47:04] <ganzuul> ...So someone already did reinvent the wheel, and they're called gears?
[19:50:22] <malcom2073> I'm going to be attempting to make a timing gear here soon
[19:58:35] <ganzuul> Why aren't screws gears too?
[20:08:36] <paul_liebenberg> hi, anyone here on Vancouver Island? I have a lathe with a dead spindle drive here and i'm trying to decide to replace the drive or convert to linuxcnc. replacement of the drive is expensive and no guarantee i will get a working machine.
[20:13:46] <fenn> ganzuul it's called a worm gear
[20:22:50] <SpeedEvil> 'replace the drive or' ?
[20:34:45] <LatheBuilder_2> paul_liebenberg, are you talking about the control, or the motor drive?
[20:36:46] <Tom_itx> yay! fixed my spindle control code for my pendant
[20:43:37] <paul_liebenberg> the motor drive.
[20:46:00] <Topy44> does anyone know what else these could be called? i found this as "fine adjustment screw" on aliexpress, but there are not many results and they are more expensive than i'd expect
[20:46:01] <Topy44> http://dump.t44.org/2015-09-10_03-21-46.png
[20:46:23] <Topy44> not looking for anything super-precise, but it needs to be cheap
[20:56:45] <MacGalempsy> when homing on a VMC, the table should be left, forward, up - correct?
[20:57:35] <PetefromTn_> usually you home the head first
[20:58:03] <PetefromTn_> where the table homes I guess depends on the locations of your home switches and whether or not you use a home offset
[20:59:22] <PetefromTn_> my machine homes with the head to the top of the column, then the table runs all the way to the right in travel and then all the way to the rear of the machine in Y axis. I use home to index and the offset I use brings the table back to center in X and all the way forward in Y
[21:02:58] <CaptHindsight> Topy44: you can try searching for them by size and pitch, e.g., 3/16-100, 1/4-80, M3-0.1
[21:03:09] <Topy44> good idea
[21:03:53] <Topy44> finding stuff on aliexpress seems to be 90% knowing what random search term to use :)
[21:06:05] <cradek> I've never seen that kind of mechanism on something
[21:07:11] <cradek> reminds me of these things: http://image.made-in-china.com/2f0j00lvGEMSTqhnkr/Furniture-Feet.jpg
[21:07:12] <CaptHindsight> http://eksmaoptics.com/out/pictures/master/product/1/870-0060_img_2012.jpg
[21:07:34] <cradek> wow that's some fine thread
[21:07:52] <Topy44> yeah they are usually used for adjusting optical systems
[21:08:01] <CaptHindsight> https://www.thorlabs.com/navigation.cfm?guide_id=131 I've seen 160tpi
[21:08:32] <Topy44> thorlabs has a large selection of them (and at pretty reasonable prices)
[21:08:38] <CaptHindsight> http://assets.newport.com/web600w-EN/images/29125.gif
[21:08:46] <CaptHindsight> 254tpi
[21:09:29] <CaptHindsight> http://www.newport.com/AJS-Series-High-Precision-Adjustment-Screws/140172/1033/info.aspx
[21:09:31] <cradek> wow
[21:09:37] <CaptHindsight> sit down for the prices
[21:09:53] <MacGalempsy> so when trying to home, the machine hits the limit the first time and it errors "hit limit in home state 7"
[21:10:05] <MacGalempsy> what does state 7 refer to?
[21:10:30] <cradek> are you using the same switch for home and limit?
[21:10:53] <MacGalempsy> yes
[21:11:04] <cradek> do you have HOME_IGNORE_LIMIT or however it's spelled for that axis?
[21:11:25] <MacGalempsy> I have that at NO
[21:11:34] <Topy44> http://assets.newport.com/web600w-EN/images/31988.jpg <== thats what you usually build from those things. and thats one hell of a nice mount...
[21:11:53] <cradek> it's gotta be YES if the limit hal pin goes high during homing and you want it to NOT stop
[21:12:09] <Topy44> essentially i need to build something that can be built for a _lot_ less money but has the same basic functionality :) (though i don't need anywhere near the precision)
[21:12:27] <cradek> Topy44: http://image.made-in-china.com/2f0j00lvGEMSTqhnkr/Furniture-Feet.jpg
[21:12:42] <Topy44> haha
[21:12:49] <Topy44> yeah...not quite the same :)
[21:12:56] <cradek> well you could epoxy a ball bearing to the end of it
[21:17:55] <SpeedEvil> Topy44: does this need to look good?
[21:18:05] <Topy44> nah
[21:18:09] <Topy44> not really
[21:18:53] <Topy44> i have an idea, just trying to figure out if it can work
[21:24:13] <maZer`GTi-> fl.. Polar co-ordinates-angle = rotation angle
[21:24:25] <maZer`GTi-> can someone tell me what to enter to do a full circle?
[21:24:28] <maZer`GTi-> 360 doesnt work :(
[21:24:50] <cradek> explain more about what you're trying to do
[21:25:27] <archivist> and did you set wrapped rotary
[21:25:47] <maZer`GTi-> N65 G12 I0. J0. H360 Z-2.
[21:25:53] <cradek> are you asking about how to program an arc, or something else?
[21:26:02] <maZer`GTi-> im trying to do a hole in helix :( with tnc155
[21:26:03] <cradek> that code means nothing to me
[21:26:15] <cradek> just moving XYZ?
[21:26:20] <cradek> you do that with G2 or G3
[21:26:23] <maZer`GTi-> my current position is x-20 y0
[21:26:43] <maZer`GTi-> cradek yes but my controll doesnt support Helix with G2 or G3 :(
[21:27:00] <cradek> so you're not asking about linuxcnc?
[21:27:05] <maZer`GTi-> also i cant use Z on my G2 or G3 command :(
[21:27:25] <maZer`GTi-> yes im sorry im trying to get this running and then retrofit to linuxcnc
[21:27:26] <maZer`GTi-> :(
[21:27:30] <cradek> ok realize we're not mind-readers here
[21:27:42] <cradek> I don't know how other controls do helixes, sorry
[21:27:58] <maZer`GTi-> yes im sorry :(
[21:28:24] <cradek> I'm sorry for being snippy
[21:28:35] <cradek> google the name of your control and maybe you can find documentation?
[21:29:16] <maZer`GTi-> yes i found but i read all out H is the Angle of Target position after the circle
[21:30:41] <cradek> I think a lot of controls, maybe all of them, have worse arcs/helixes/polar coordinates than linuxcnc, haha
[21:31:03] <furrywolf> tiwake: fix your monitor yet?
[21:31:51] <maZer`GTi-> yes i know :( used linuxcnc before, was great. But Servo Controllers die... :(
[21:41:28] <PetefromTn_> I love this Picatinny rail program I made... it runs so smooth and just a couple toolchanges. Perfect rail every time!! ;)
[21:42:21] * furrywolf owns nothing with picatinny rail
[21:43:45] <PetefromTn_> neither does petefromtn :D
[21:44:20] <PetefromTn_> but as long as people keep ordering them I will happily keep machining them!
[21:44:28] <furrywolf> lol
[21:45:32] * furrywolf waits for PetefromTn_ to get sued after someone whackjob shoots someone, because after all, equipment manufacturers are entirely responsible for how their tools get used. just ask any lawyer...
[21:45:44] <malcom2073> Is it cheaper to have them custom made than to buy them PetefromTn_?
[21:46:16] <PetefromTn_> hell I dunno....
[21:46:18] <malcom2073> lol
[21:46:20] <furrywolf> it's like when some guy shot a bunch of people, and the survivors sued the online store he ordered the ammo from, saying they shouldn't have sole ammo to a dangerous individual.
[21:46:47] <furrywolf> sold
[21:46:51] <PetefromTn_> yeah we have a special kind of stupid going on in our country right now LOL
[21:47:32] <PetefromTn_> malcom2073 did you get the idea these are crazy expensive or something heh
[21:48:00] <malcom2073> PetefromTn_: I dunno, iirc they were like $40 for a 6" rail, we used them on stuff at work, but it's been forever since I looked
[21:48:16] <malcom2073> The clips that mount to them are the expensive part heh
[21:48:54] <PetefromTn_> well I am not exactly marking these to the moon... but whatever I am asking for them I have LOTS of repeat customers now so I must not be too far gone off the mark
[21:49:03] <malcom2073> Awesome
[21:49:13] <malcom2073> Though one thing I've found: It's tough to find two vendors that make identical rails
[21:49:15] <PetefromTn_> it is indeed
[21:49:16] <malcom2073> iow: to spec
[21:49:22] <PetefromTn_> OH hell yeah
[21:49:31] <malcom2073> Maybe thats it, yours are actually to spec :)
[21:49:37] <PetefromTn_> I inspected quite a few to get the feel for this
[21:49:46] <malcom2073> I swear some of these vendors use raw castings for their rails they're so crap
[21:49:53] <furrywolf> That's the nice thing about standards... there's so many to choose from. :P
[21:49:54] <PetefromTn_> and of course consulted the internet for drawings/dimensions
[21:50:10] <PetefromTn_> so far I have never had anyone complain about fitment
[21:50:39] <PetefromTn_> I also test fit quite a few different accessories and rings to my rails to ensure that MOST would fit properly.
[21:50:58] <PetefromTn_> What I found was that many are cast or plastic crap and are nowhere near to spec LOL
[21:51:16] <PetefromTn_> but still most everything I found to install on my rails fit without too much drama
[21:51:51] <furrywolf> make a multi-part rail with tapered gibs that you can adjust to fit your accessories. :P
[21:57:23] <PetefromTn_> uh no
[22:13:18] <furrywolf> so, every year stores start putting up holday garbage earlier and earlier... CVS already has a fucking CHRISTMAS display.
[22:13:42] <PetefromTn_> I love Christmas ;)
[22:13:45] <renesis> my friends wife spends so much on stupid decoration shit
[22:14:04] <renesis> also ornamental bath towells that dont work
[22:14:52] * furrywolf does not
[22:15:25] <furrywolf> I like neither religion nor consumerism.
[22:15:58] <PetefromTn_> hell you don't like anything
[22:16:28] <furrywolf> "Mig Welder - $675" "Miller Machine Complete, make offer " I also don't like people who think that's enough information for a craigslist ad. no, it does not have a picture.
[22:16:50] <PetefromTn_> could be a smokin' deal or a piece of shit
[22:18:09] <furrywolf> what I really want next is a TIG setup, but there's none on craigslist.
[22:19:15] <PetefromTn_> I have a family member that does a lot of tig welding for race cars etc. He bought one of those everlast tig units and has had it almost ten years he said. He recommended it. they are relatively reasonably priced
[22:19:38] <roycroft> i have an everlast tig welder
[22:19:42] <roycroft> i don't use it much, but it works great
[22:19:46] <PetefromTn_> I am considering getting another tig to have here at the house and that is one of the ones I am considering
[22:19:48] <roycroft> and it was quite reasonably priced
[22:19:53] <PetefromTn_> oh yeah which model?
[22:20:41] <PetefromTn_> https://knoxville.craigslist.org/bar/5210136995.html I like these deckboats...
[22:20:49] <roycroft> powertig 250ex
[22:20:56] <roycroft> with a cooler
[22:21:03] <PetefromTn_> ooh that is the one I want
[22:21:19] <roycroft> it seems the perfect model for someone who doesn't weld all day logn
[22:21:21] <roycroft> long
[22:22:05] <roycroft> i'm not a great welder, but i was able to weld aluminium nicely from the get-go
[22:22:16] <roycroft> ss has been a bit more of a challenge, but i can weld that ok now
[22:23:04] <roycroft> anyway, i would highly recommend it
[22:23:15] <roycroft> it's a great welder, and the folks are everlast are awesome
[22:23:25] <furrywolf> I'm going to get whichever TIG unit shows up on craigslist that the owner will take a honda generator in trade. :P
[22:23:26] <roycroft> very customer service oriented
[22:23:53] <roycroft> i also have an everlast plasma cutter, but i've only used it a handful of times
[22:24:01] <roycroft> i'm thinking of selling it just because i don't use it much
[22:24:22] <roycroft> cash takes up less space than the plasma cutter, and is more versatile
[22:24:46] <furrywolf> I have a Marquette plasma cutter I've never used. guy I got it from said it only needed new consumables, but I think it needs a new gun.
[22:29:03] <PetefromTn_> sweet...
[22:29:44] <PetefromTn_> yeah that everlast 250 is about perfect for my needs here doing the extra stuff for the race shop guys and the walk in stuff while I keep my commercial machine at the shop
[22:30:08] <PetefromTn_> how long have you had it?
[22:30:58] <furrywolf> gah, I'm really tired... but it's only 8pm.
[22:31:08] <furrywolf> lawyers are exhausting.
[22:31:09] <PetefromTn_> I gotta work in the morning
[22:31:25] <PetefromTn_> just glad I got this rail finished tonight, turned out beautiful
[22:31:40] <furrywolf> I gotta work every morning!
[22:31:40] <PetefromTn_> just gotta deburr this bad boy and get it brush finished and packed up to ship.
[22:32:01] <PetefromTn_> Oh so do I but I just meant I work outside my shop tomorrow
[22:32:31] <PetefromTn_> I ordered two 12 foot lengths of that 6061 1x2inch material gotta pick it up tomorrow afternoon
[22:32:43] <PetefromTn_> should keep me in rails for a couple days hopefully
[22:33:04] <PetefromTn_> I want to order a crapload of it and get a better deal but I don't have the capital on hand for that right now
[22:34:14] <furrywolf> if you need a metric crapload, you can get a custom extrusion with the T profile already done for you...
[22:34:38] <PetefromTn_> yeah but that is even more expensive I think
[22:34:58] <PetefromTn_> the way I machine these I don't know if it would really help all that much
[22:37:56] <PetefromTn_> well gotta hit the sack. Goodnight folks
[22:37:58] <roycroft> if you were talking to me, petefromtn_ (i stepped out for a bit), i've had my everlast gear for about 3 years
[22:38:09] <PetefromTn_> oh yeah I was
[22:38:17] <PetefromTn_> thanks for the review
[22:38:41] <roycroft> i really do like it
[22:38:44] <PetefromTn_> did yours have the digital display?
[22:38:50] <roycroft> and i don't care that it's not red or blue
[22:38:52] <roycroft> yes
[22:38:56] <PetefromTn_> or is it the earlier one with knobs
[22:38:57] <roycroft> but it's an analog welder
[22:39:12] <roycroft> it's one of the in between models
[22:39:18] <PetefromTn_> ok
[22:39:25] <roycroft> they still sell it
[22:39:31] <PetefromTn_> i know they made an earlier one with knobs and smaller digital display
[22:39:46] <roycroft> also, and i'm not sure if they still do this, but they were really trying to get some market share when i bought my stuff
[22:39:50] <PetefromTn_> then they made a newer one that was all digital with modern buttons etc.
[22:40:11] <roycroft> iirc the list price on everything i got was about $3200, and i offered them substantially less, like $2400, and they went for it
[22:40:17] <roycroft> i also demanded free shipping
[22:40:34] <PetefromTn_> is that for the welder only or the welder and plasma?
[22:40:47] <roycroft> i got the tig welder, cooler, plasma cutter, two carts, and some accessories
[22:40:55] <PetefromTn_> oh okay nice
[22:41:06] <roycroft> if you buy the welder get the cooler
[22:41:16] <PetefromTn_> at one point the 250 was only like $1500 as I recall but it has gone up quite a bit now
[22:41:28] <roycroft> i think current list is $1699
[22:41:35] <roycroft> and $500 for the cooler
[22:41:46] <PetefromTn_> I don't use a cooler on my tig
[22:41:48] <roycroft> $850 for the plasma cutter
[22:41:52] <roycroft> hmm
[22:41:59] <PetefromTn_> and even if I wanted to I would just make one probably LOL
[22:42:03] <roycroft> i've run mine without the cooler and the torch gets really hot really fast
[22:42:17] <PetefromTn_> do you have an air cooled torch?
[22:42:25] <roycroft> no
[22:42:30] <roycroft> and that may be why i need the cooler
[22:42:43] <roycroft> i don't know - i'm not an expert on such things
[22:42:55] <PetefromTn_> I have welded all sorts of stuff with my commercial tig with the air cooled torch and never had a problem unless I was really hitting it hard on AC
[22:42:55] <roycroft> i just know that i consider the cooler essential because i don't like holding on to hot things
[22:43:10] <PetefromTn_> heh who does
[22:43:30] <PetefromTn_> what size torch do you have?
[22:44:58] <PetefromTn_> my family member Chris who has the same tig welder said the torch they give you with it is kind of a piece of junk and he swapped out to a much nicer weldcraft but he does use a cooler he built and a number 20 torch
[22:45:31] <MacGalempsy> I am having trouble with the z homing. It worked fine once, then when rehoming it did not work the second time. when the head hits the z max, then the z-max-endstop activates
[22:45:59] <roycroft> i don't remember the size designations
[22:46:01] <MacGalempsy> even though I tell it to Home_ignore_limits
[22:46:04] <roycroft> but the one that comes with it is big
[22:46:07] <roycroft> and it's fine for big stuff
[22:46:14] <roycroft> but i do smaller stuff, and bought a smaller one off ebay
[22:46:18] <roycroft> one moment
[22:46:31] <PetefromTn_> do you use the finger switch or foot pedal?
[22:46:57] <roycroft> http://www.ebay.com/itm/140505891685?_trksid=p2055119.m1438.l2649&ssPageName=STRK%3AMEBIDX%3AIT
[22:47:00] <roycroft> that's what i use
[22:47:03] <roycroft> and i use the pedal
[22:48:23] <PetefromTn_> that looks like a 20 with flex head.. nice. Never heard of weldtec tho. Do you like it?
[22:48:30] <roycroft> yes, it seems to work fine
[22:48:41] <roycroft> but again, i'm not really a welder
[22:48:47] <roycroft> so take anything i say with a grain of salt
[22:48:56] <roycroft> i just weld at things occasionally :)
[22:48:59] <PetefromTn_> well you got a welder....so you're a welder LOL
[22:49:17] <roycroft> i have turned two pieces of metal into one many times
[22:49:26] <roycroft> and almost all the time they remain one piece after
[22:49:38] <roycroft> so i guess that says something
[22:49:46] <PetefromTn_> the fact that you have a nice tig unit with cooler and everything puts you in at several notches above the guy with the buzzbox in the garage or even the flux core pos welder LOL
[22:50:23] <PetefromTn_> and you said you can weld aluminum well so that is not really too easy.
[22:50:31] <PetefromTn_> but I get your point
[22:50:37] <roycroft> i find it easier than welding stainless
[22:50:45] <PetefromTn_> Okay gotta get to bed. Thanks for sharing
[22:50:47] <roycroft> sure
[22:50:49] <PetefromTn_> good night man
[22:50:53] <roycroft> i need to head back to the shop for a bit myself
[22:51:03] <roycroft> it's dark but not too late to make noise for a while longer
[22:52:50] <furrywolf> my shop is inside my storage unit, and they lock the gate at 8pm. no late-night chipmaking. :)
[22:53:19] <furrywolf> (they don't even let you out if you're already in... you have to call to be let out, and they charge you ten bucks to remind you not to do it again)
[22:56:38] <LatheBuilder_2> paul_liebenberg, linuxcnc does not replace the drives but the control. Your drives need to be good for any control to work.
[22:58:48] <rue_school> if I have a variable with the string "hello world" can I make a second string that is just the first 4 characters from it?
[22:59:27] <rue_school> I googled for linuxcnc stirng functions and google gave me a lot of results that dont have any of the things I'm looking for in them
[23:00:02] <furrywolf> linuxcnc has string functions? shows how much I know!
[23:01:01] <rue_school> well, I cant prove that yet
[23:01:04] <rue_school> I should hope so
[23:07:14] <LatheBuilder_2> paul_liebenberg, i should qualify: linuxcnc replaces the software component of the control.
[23:12:37] <Jymmm> furrywolf: ...only in theory
[23:16:06] <furrywolf> bbl, wolfy bedtime
[23:54:09] <MacGalempsy> while homing my z hits the upper max / home then kills the power
