[02:29:26] <Deejay> moin
[04:48:46] <XXCoder> boo
[05:20:21] <jthornton> morning
[05:20:29] <XXCoder> yo
[05:20:33] <XXCoder> how goes project
[05:21:38] <jthornton> put the hoe back together and found out I changed the wrong hose then it started to rain lol
[05:21:56] <jthornton> blasted a part in the new blast cabinet so that is coming along
[05:22:05] <XXCoder> lol
[05:22:23] <jthornton> the hose is under the hoe and hard to see
[05:25:44] <XXCoder> this kinda pissed me off http://distractify.com/animals/2016/06/23/vegan-dog-owner-gets-owned
[05:25:57] <XXCoder> be vegan fine, don' make your pet vegan if its meat eater
[05:26:12] <XXCoder> dogs and cats is not human
[05:26:46] <XXCoder> my sis has one cat thats always very thin and small. its because it had vegan foods when it was growing up. my sis started it on meat when she got her
[05:31:28] <jthornton> guy above was worried about calling me at 9pm lol I leave my phone in the shop
[05:41:42] <XXCoder> heh well
[06:30:58] <jthornton> I thought I would get more orders than one every other week...
[06:31:20] <XXCoder> parts orders?
[06:31:36] <XXCoder> cnc jobs has been little bit slow this year
[06:31:37] <jthornton> for Mesa cards
[06:31:46] <XXCoder> oh you make em?
[06:32:02] <jthornton> I'm a distributer for Mesa
[06:32:11] <XXCoder> ahh cool
[06:32:19] <XXCoder> I wonder how good mesa is
[06:32:22] <jthornton> http://mesaus.com/
[06:32:34] <XXCoder> I do want to evenually upgrade my machine with better motors and controller
[06:32:36] <jthornton> the best you can get IMHO
[06:33:40] <jthornton> what kind of machine do you have?
[06:33:53] <XXCoder> small chinese router lol
[06:34:03] <jthornton> steppers?
[06:34:09] <XXCoder> currently yeah
[06:34:25] <jthornton> http://mesaus.com/index.php?route=product/product&path=69&product_id=78
[06:34:54] <XXCoder> thats a lot of connectors
[06:35:25] <jthornton> http://mesaus.com/index.php?route=product/product&path=62&product_id=69
[06:35:30] <jthornton> less connectors
[06:35:57] <XXCoder> interesting
[06:37:37] <jthornton> I wonder if my problem is I use paypal to take credit cards???
[06:37:50] <XXCoder> hard to say
[06:38:07] <XXCoder> I have been selling lego parts for years.
[06:38:35] <XXCoder> 6 years I guess, I'm largely "retired" from that lol
[06:38:42] <XXCoder> anyway market goes up and down
[06:38:50] <XXCoder> and it can be hard to predict
[06:40:10] <archivist> starting a business is never fast
[06:40:18] <XXCoder> indeed
[06:40:28] <Tom_itx> JT-Shop, did that 10 patch work for you?
[06:41:08] <jthornton> didn't get a chance to try it, yesterday was a screwed up day from the git go
[06:41:12] <archivist> sue M$ http://www.bbc.co.uk/news/technology-36640464
[06:42:11] <archivist> jthornton, I am not getting even one job a year for gear cutting
[06:43:01] <XXCoder> yeah I have interned at places, they ran damn old software
[06:43:14] <XXCoder> I saw one system running os/warp 2
[06:43:21] <XXCoder> that was few years ago
[06:46:21] <jthornton> dang 66f outside
[06:47:47] <jthornton> I should take the road bike out for a spin
[06:48:24] <jthornton> archivist: you do more than just clock gears?
[06:48:59] <archivist> a few odd and sods
[06:49:52] <archivist> the manuals archive gets a few donations for scans
[06:51:58] * jthornton goes to see if the mud has dried up around the broken hoe
[06:54:42] <archivist> use the hoe to dig an inspection pit so you work on its underside
[06:58:36] <JT-Shop> no hydraulics at the moment...
[07:01:34] <archivist> I did realise the chicken egg situation :)
[07:04:18] <XXCoder> just ask doc who to borrow working backhoe from past to dig a hole
[07:04:35] <XXCoder> or be more murdune and use shovel
[07:13:50] <JT-Shop> during the monsoon I would walk up there and get my boots covered with mud then walk back and hose them off... really slow dirt moving
[08:06:34] <JT-Shop> got the offending hose out without taking the hoe half way apart :)
[08:10:52] <lair82> Good Morning Guys, how do I go about setting up a remote connection, to another linuxcnc machine pc that is at another shop down the road?
[08:18:14] <pcw_home> shell (terminal) or graphic connection?
[08:20:58] <lair82> Either really, I'm not sure which one would be better?
[08:26:02] <lair82> I see remmina and krdc as graphical apps, and I'm pretty confident using ssh here in the shop between all of the cnc's here, I guess I'm not sure of the advantages of using one or the other though.
[08:41:23] <Polymorphism> CNC still on hold waiting for ballscrew, begun planning the control enclosure
[08:41:39] <Polymorphism> All other assembly is clear except the Y rails
[08:41:43] <pcw_home> I guess it depends on what you are trying to do
[08:41:44] <pcw_home> ssh is likely to work better on a slower connection than any graphic interface
[08:41:56] <Polymorphism> Still need to level them though
[08:41:59] <Polymorphism> and get them parallel
[08:42:06] <Polymorphism> it's not quite clear how to do that, not in instructions
[08:42:15] <Polymorphism> so I may just assume they are good enough, and go with it
[09:16:58] <lair82> pcw_home, a lot of it would be just being able to work on the files on the target pc, but I could see there being a need to be able to look at classicladder to adjust or tweak things remotely.
[09:45:28] <KreAa> Meep meep ?
[09:45:54] * KreAa is very happy right now after getting LinuxCNC running on his new Beebox N3150
[09:46:31] <KreAa> The peraped image didn't work though, but installing ubuntu 12.04 first and adding the rtai kernel and linuxcnc from repos after worked like a charm
[10:09:22] <Spida> has anybody tried to machine foam rubber? I assume that this is something to be done with a lasercutter or mill?
[10:10:11] <gonzo__> hot knife?
[10:10:46] <KreAa> INjection molding...
[10:11:28] <_methods> supposedly you can freeze it and machine it
[10:11:33] <_methods> but i've never tried that before
[10:17:32] <KreAa> interesting
[10:17:40] <KreAa> I do that with wac
[10:17:43] <KreAa> wax
[10:19:29] <gregcnc> heh, you can mill water if you freeze it
[10:31:46] <CaptHindsight> my mill doesn't fit in the freezer
[10:32:04] <roycroft> i mill rubber on a semi-frequent basis
[10:32:10] <roycroft> i freeze it and it machines fine
[10:33:26] <CaptHindsight> gregcnc: I heard that if you heat ice it starts to flow and then it may be molded and cooled
[10:33:46] <roycroft> i should think, though, that foam rubber would have to be very cold to withstand the rigors of machining operations on it without deforming
[10:34:35] <CaptHindsight> depends on the foam, foam rubber is like saying metal
[10:35:01] <roycroft> yes
[10:38:05] <Spida> do you get problems with condensation when freezing foam rubber? will it ever dry again?
[10:41:21] <archivist> is it closed foam or open
[10:44:12] <enleth> CaptHindsight: it would be interesting to put a mill in a walk-in freezer
[10:44:41] <enleth> that would probably do bad things to fits in bronze bushings
[10:44:52] <enleth> but you could mill ice blocks
[10:45:10] <JT-Shop> hoe is alive
[10:45:22] <_methods> put that hoe back on da street then
[10:46:07] <gregcnc> https://youtu.be/uVEqEv6BRNc
[10:46:32] <CaptHindsight> enleth: yeah, just modify anything in the mill to compensate for temp
[10:46:50] <Frank_12> jt shop! your awesome
[10:46:55] <Frank_12> thanks for the prompt delivery
[10:47:53] <JT-Shop> you got it already?
[10:47:59] <Frank_12> no, lol
[10:48:00] <CaptHindsight> I'm putting some X-Y in an oven that goes over 200C. I have to compensate for the 200+ deg delta
[10:48:12] <Frank_12> but u sent me the email saying that it has been shipped,
[10:48:58] <JT-Shop> yea, I ship each morning before 10 so the packages go out to the distribution center that day
[10:50:47] <CaptHindsight> gregcnc: I'm going to bring one of those to lake Geneva next year for the Winterfest. Just not park it on the lake :)
[10:50:48] <Frank_12> yeah, but amazing, i mean i payed really late and still you managed to send it as soon as you can, besides you already saved me 80bucks by having in stock the 7i76 hehe
[10:51:35] <JT-Shop> yea, I process orders in the morning so any order that makes it to my inbox by 8 or so goes out that day
[10:52:25] <cradek> wow
[10:52:34] <BeachBumPete> Man I can't wait to install my mesa boards.... starting to feel like it is neva gonna happen LOL
[10:52:49] <Sync> still no house?
[10:52:57] <Frank_12> tell me about it, i've started my cnc router build almost 1 year ago,
[10:52:59] <BeachBumPete> oh there's a house
[10:53:09] <BeachBumPete> its just not OFFICIALLY ours yet ;)
[10:54:45] <BeachBumPete> visited the house yesterday and the seller had done a bunch of work including installing brand new smoke and fire detectors in almost every room as well as a brand new garage door opener with remotes and he has been working on the master bathroom shower drain which was slowly draining for some reason. There were a lot of little things that needed attention found during the home inspection...
[10:55:39] <BeachBumPete> that and the mountains of paperwork needed for an FHA loan nowadays has pushed off the closing twice now..
[11:18:11] <BeachBumPete> this is probably a stupid question but what is the easiest and preferrably free way to fax a doccument from a printer/scanner etc?
[11:21:42] <JT-Shop> your smart phone
[11:22:20] <BeachBumPete> hm so what scan the files and load them to the phone then what? is there an app for this?
[11:23:07] <JT-Shop> I just take a photo and text it
[11:24:35] <BeachBumPete> ah I see, I am trying to send my resume to some employers in PSL right now..
[11:24:36] <JT-Shop> and just looking there is fax software for your phone
[11:25:27] <JT-Shop> http://www.verizonwireless.com/archive/mobile-living/tech-smarts/send-fax-from-phone-mobile-fax/
[11:25:57] <JT-Shop> opps that's $$$$
[11:26:32] <CaptHindsight> I see that there are still several fax from your PC over the internet scam sites
[11:27:59] <BeachBumPete> I found an app that does send receive faxing gonna try it. thanks for the suggestion. Probably scam stuff but well see.
[11:28:23] <jdh> email a pdf
[11:28:26] <CaptHindsight> 30 day free trial, and figure that you'll forget to cancel
[11:28:42] <BeachBumPete> apparently it is only free for 10 faxes a month..
[11:29:04] <CaptHindsight> last time I tried none of them ever made it to the destination
[11:29:11] <CaptHindsight> see how they work
[11:30:20] <BeachBumPete> I just deleted that APP trying another one now :D
[11:32:43] <CaptHindsight> BeachBumPete: heard that the new Independence Day isn't quite as good as the last one... but that's a review from someone that was 3 when the first one came out
[11:32:51] <jdh> it's 2016 and you are trying to fax. do you use paper tape on your numerical control machines?
[11:33:20] <CaptHindsight> faxes are still routine in the medical industry in the USA, sad to say
[11:33:39] <BeachBumPete> Jdh honestly its not my choice man
[11:34:22] <BeachBumPete> CaptHindsight hmm that sucks I am looking forward to seeing it.
[11:34:54] <CaptHindsight> it's like Transformers, non stop special effects
[11:35:32] <BeachBumPete> that is not necessaryily a bad thing
[11:36:00] <CaptHindsight> I still get asked for my fax number
[11:37:05] <CaptHindsight> I usually reply that we had that line removed along with our floppy drives
[11:40:07] <FloppyDisk> BeachBumPete - I like CamScanner: take pic, it converts it to PDF, email/text/etc from phone. Free and seems to be a decent app.
[11:40:08] <djdelorie> last time someone told me to fax something, I just said "what's faxing?"
[11:42:27] <Frank_12> lol
[11:42:48] <BeachBumPete> Hey man I am not the one asking for a faxed resume' LOL
[11:43:48] <BeachBumPete> I have a scanner here and I already scanned the pages into the thumb drive. Not just gotta get it into a fax mode somehow without paying hopefully. You would think this would be a simple thing to do on any pc or phone
[11:44:40] <gregcnc> will they not take it by email?
[11:45:29] <BeachBumPete> honestly a lot of the ads just have a fax number and little else typically unless they were BRAVE enough to actually leave the name of their company and GASP their phone number LOL
[11:47:22] <roycroft> i use an ip fax service these days
[11:47:31] <roycroft> iirc it costs me $0.03 per page for send or receive
[11:47:35] <gregcnc> i looked at this a while back. if you have to do a bunch of faxing the fees are reasonable
[11:47:48] <roycroft> my voip provider has this service
[11:48:29] <roycroft> i can use a web interface to send files via fax, or i can print to fax
[11:48:37] <roycroft> i use it maybe 6x/year :)
[11:48:49] <roycroft> but when i need to use it it sure is handy
[11:55:48] <BeachBumPete> gonna try a phone app but for some odd reason my thumbdrive is not getting recognized by my laptop :(
[12:03:21] <KreAture> Getting my mPCIe LPT port in a few days :)
[12:45:40] <CaptHindsight> KreAture: does it use a PCIe channel or USB?
[12:47:08] <KreAture> pcie
[12:47:34] <KreAture> I checked which host it uses and it is a pcie bridge controller chip
[12:48:14] <KreAture> I may get some free time soon, maby I should crowdfund one, make a board specifically designed to be linuxcnc compatible :)
[12:49:08] <KreAture> serial ports, are they usefull at all for linuxcnc ?
[12:49:17] <KreAture> anyone use em for spindle control or something ?
[12:49:59] * SpeedEvil ponders a small FPGA
[12:53:54] <KreAture> SpeedEvil the major reason I do not like the fpga is the extra coding
[12:54:08] <SpeedEvil> fair enough
[12:54:10] <KreAture> You start moving the control out of linuxcnc
[12:54:22] <KreAture> I believe that was the general concern first time it was done too
[12:54:44] <KreAture> http://wiki.linuxcnc.org/cgi-bin/wiki.pl?HardwareDesign
[12:55:19] <KreAture> I do believe that a lot of this is anchient though
[12:55:27] <KreAture> when stuff was 133 MHz vs 2.6 GHz
[12:55:29] <KreAture> etc
[12:55:52] <KreAture> any decent pid should handle tiny phaseshifts etc
[12:56:13] <KreAture> The timeframe it should control most stuff at is much longer than the loop time
[12:56:39] <KreAture> still, I get it. Also it simplifies the hardware
[12:57:30] <KreAture> My dma option is a tad different than the external controller stuff too, as any motion can be stopped, and the buffer examined for move to be rewound to the point it halted.
[12:58:02] <KreAture> This generates buffered output of pulsestream while allowing homing and such to work on 1 step accurate position
[12:58:33] <KreAture> I have however not published any working code so it's still airtalk :)
[13:17:10] <Sync> KreAture: there is no reason not to push the control out from linuxcnc
[13:17:33] <KreAture> :)
[13:18:52] <Sync> you still only get as much movement as you have in one cycle
[13:20:31] <FloppyDisk> BeachBumPete - efax... I've had an account since the 90's, not sure if they're still free, but I can fax and receive faxes via there system. Might be others now...
[13:21:14] <BeachBumPete> FloppyDisk thanks man I think I got it now tho... at least I sent it we will see if they actually receive anything LOL
[13:22:00] <_methods> faxzero is free
[13:22:05] <_methods> how many pages?
[13:22:06] <FloppyDisk> Sounds good. Good luck - there are still businesses that are fax driven, it's insane...
[13:22:15] <_methods> i think they do 3 pages free or something
[13:22:29] <BeachBumPete> Well I think a lot of legal doccuments are actually safer when faxed apparently
[13:22:53] <_methods> yeah 3 pages max and you can send 5 faxes a day free
[13:22:58] <BeachBumPete> they now have secure PDF files you can use but they are still crackable from what I gather
[13:23:06] <_methods> 3 pages + 1 cover
[13:23:28] <Sync> I would not consider a fax to be safe
[13:23:51] <Sync> it is only legally safe here if you have an analog fax on both sides
[13:23:51] <_methods> i think it's because they're considered legal not safe
[13:24:23] <_methods> for signed legal documents at least
[13:24:38] <BeachBumPete> well many of the doccuments we have been sending to the lender for our home loan they recommend faxing instead of emailing due to security concerns
[13:25:18] <BeachBumPete> a lot of financial and identity information going back and forth
[13:25:18] <Sync> haha
[13:25:46] <BeachBumPete> something funny?
[13:26:36] <_methods> i think he's laughing at the misconception that a fax would be more secure
[13:27:00] <BeachBumPete> Ok
[13:27:13] <_methods> but i'm just guessing that was what he is laughing at
[13:27:42] <_methods> any sort of electronic communication could be subject to interception but that's hardly news
[13:28:07] <BeachBumPete> sure but internet is pretty well wide freaking open anymore
[13:28:35] <_methods> hell i think the CIA had some device that could capture your monitor electronic emissions and recreate your screen out in their surveillance vans
[13:29:04] <Sync> well, I'd not be emailing or faxing any of my information
[13:29:06] <BeachBumPete> honestly I am just telling you what they told us and my bank here agreed with it so it is what it is..
[13:29:11] <Sync> they can have it if we meet
[13:29:15] <_methods> https://en.wikipedia.org/wiki/Van_Eck_phreaking
[13:29:25] <Sync> yeah, I guess faxing would be better but eh
[13:29:31] <_methods> not that anyone uses crt anymore
[13:29:48] <_methods> oh nm
[13:29:54] <_methods> lcd is susceptible too lol
[13:30:12] <BeachBumPete> Sync I would much prefer meeting them in person but there are SO many papers they need and on several different occasions and the lender is based several hundred miles away
[13:30:41] <_methods> yeah sometimes you gotta take the tin foil hat off to get something done lol
[13:31:26] <BeachBumPete> I am just simply amazed at the amount of paperwork and verification they have wanted on my entire LIFE just to get a damn secured home loan..
[13:32:24] <_methods> it was a stupid amount of paper before the housing market stupidity
[13:32:30] <_methods> i can only imagine how bad it is now
[13:32:32] <BeachBumPete> agreed..
[13:32:53] <_methods> i'm just building one from scratch next time
[13:32:58] <_methods> no more HOA's
[13:33:01] <_methods> no more neighbors
[13:33:07] <BeachBumPete> my mother in law actually recently bought a home in California and she said the same things.... Just stupid amount of paperwork and red tape
[13:33:11] <_methods> get some acres and build
[13:33:31] <BeachBumPete> can't really do that around here man...
[13:33:44] <_methods> yeah
[13:33:54] <_methods> well i don't need civilization too much anymore thanks to amazon
[13:34:09] <_methods> no need to live near anything except for internet connection
[13:34:16] <BeachBumPete> hell even in Tennessee we had neighbors and they had HOA's but there is still land I hear they are making in say Montana or alaska?
[13:34:31] <Sync> _methods: nah, it works pretty well without taking it off
[13:34:39] <_methods> hahah
[13:34:51] <_methods> you gotta let your hair breath every once in awhile
[13:35:34] <BeachBumPete> we rented a sort of cabin in the mountains of Tennessee when we first moved there and that was about as isolated as I would have ever wanted... I still need supplies and stores and whatnot..
[13:36:08] <BeachBumPete> hell even the UPS driver had trouble finding us in that house ;)
[13:36:13] <_methods> hahah
[13:36:41] <_methods> we're probably going to find some land between charleston and savannah you can still find it around here
[13:36:53] <_methods> right between my 2 favorite cities hehe
[13:37:14] <BeachBumPete> I wish there was an ideal place for me
[13:37:57] <BeachBumPete> I love the ocean and I love saltwater fishing but I also like my privacy and that feeling that if someone is coming down your road you either know them or they are REALLY lost....
[13:38:36] <BeachBumPete> but unless you are REALLY wealthy and well to do that is not gonna happen
[13:41:52] <JT-Shop> I just make the best of where I'm at...
[13:41:52] <_methods> is it that hard to find some acres around there?
[13:42:13] <_methods> you have a lot of hoe trouble
[13:42:26] <_methods> in your neighborhood lol
[13:42:32] <BeachBumPete> huh?
[13:42:41] <JT-Shop> damn hoes
[13:42:43] <_methods> JT-Shop's hoes be actin up
[13:43:00] <JT-Shop> slap that bitch into next week
[13:43:11] <BeachBumPete> I met his wife very briefly and I am surprised she takes that sort of crap ;)
[13:43:18] <_methods> hehe
[13:43:27] <JT-Shop> lol
[13:43:45] <JT-Shop> she has more knifes in her purse than I have in my pocket
[13:43:53] <_methods> so we just got 2 haas tm-1's
[13:43:59] <JT-Shop> or knives
[13:44:04] <_methods> got one for $12500 and the other for $11300
[13:44:07] <BeachBumPete> its not the knives in the purse its the purse itself from what I understand
[13:44:28] <BeachBumPete> _methods why?
[13:45:23] <_methods> we got them for the shop
[13:45:38] <_methods> to replace an old bridgeport ez trak
[13:45:54] <BeachBumPete> well I suppose they would replace one of those
[13:46:07] <_methods> yeah
[13:46:11] <BeachBumPete> the shop I worked in briefly with my friend Sammy in Tennessee had two of those....
[13:46:24] <_methods> yeah its nice has cat40
[13:46:28] <_methods> instead of r8
[13:46:29] <BeachBumPete> the only good thing about it was the one had like 30 inches of x
[13:46:52] <BeachBumPete> other than that it was very slow and not exactly the most rigid thing I ever ran...
[13:46:57] <_methods> yeah they are 30x12x16 or something like that
[13:47:03] <BeachBumPete> yup
[13:47:12] <BeachBumPete> kinda like a bridgeport
[13:47:22] <_methods> yeah it's for our manual guys
[13:47:30] <_methods> so they have a little cnc capability
[13:47:44] <BeachBumPete> It would make a great garage machine tho
[13:47:49] <_methods> yeah
[13:47:51] <gregcnc> but not too much?
[13:47:57] <_methods> not too much
[13:48:03] <_methods> you don't want manual guys having too much
[13:48:11] <_methods> you can't trust those guys
[13:48:20] <gregcnc> auction?
[13:48:23] <_methods> yeah
[13:48:39] <BeachBumPete> _methods is the auction queen ;)
[13:48:43] <_methods> yes
[13:48:44] <BeachBumPete> er king
[13:48:57] <jdh> whatever works for you
[13:48:59] <_methods> auction whore is my official title
[13:49:03] <gregcnc> doesn't matter which door you use to get in the auction anymore
[13:49:39] <_methods> hehe
[13:49:51] <BeachBumPete> I need to find some local machinery auctions here
[13:50:03] <_methods> yeah this one is just outside atlanta
[13:50:19] <_methods> must be nice to live in ohio
[13:50:21] <BeachBumPete> I would really like to get a 4th at some point
[13:50:25] <_methods> they have like 10 auctions a day up there
[13:50:33] <_methods> yeah i keep an eye out for ya
[13:50:44] <BeachBumPete> uh huh
[13:50:54] <_methods> i do
[13:51:16] <gregcnc> how do you find them, interwebs or ?
[13:51:21] <BeachBumPete> you're probably like......hey man look at that SWEET 4th axis....bet that jackass pete on the IRC would love to have that one....teeheeheee
[13:51:22] <_methods> internet
[13:51:38] <_methods> we go to so many auctions we get fliers all teh time too
[13:51:39] <gregcnc> the only stuff I see local are on bidspotter occasionally some random source
[13:51:44] <_methods> once you sign up for a couple
[13:52:03] <_methods> then you get auction fliers by the mountain
[13:52:34] <gregcnc> sure, like sending an inquiry about a machine and your spam box fills up with offers from italy and brazil
[13:52:43] <_methods> i just got that dynasty 200 for $880 for myself
[13:52:46] <_methods> that was a nice score
[13:52:52] <_methods> no foot pedal or torch though
[13:53:10] <_methods> so that will cost me about as much as the damn dynasty i'm sure
[13:53:18] <BeachBumPete> naah
[13:53:33] <BeachBumPete> the torch at least is not too bad really
[13:53:39] <_methods> yeah
[13:53:42] <BeachBumPete> if you want really long cables it gets pricey
[13:53:43] <_methods> the foot pedal though
[13:53:49] <_methods> that's gonna hurt
[13:54:06] <BeachBumPete> you can get a torch handle control if you want
[13:54:13] <_methods> yeah that might be cheaper
[13:55:16] <_methods> ouch $289 at arc-zone
[13:55:24] <_methods> https://www.arc-zone.com/foot-control-a-mfc-14?gclid=CPie0uOsy80CFU0vgQody0YCjw
[13:57:56] <_methods> i figure i should be able to sell that ltec for $1000 or so
[13:58:29] <BeachBumPete> probably
[13:58:54] <_methods> hard to find a working tig rig with pedal and torch for under $1k
[13:59:26] <_methods> even those chinese tig rigs cost that much
[14:00:09] <CaptHindsight> depends on features
[14:00:24] <_methods> the ltec has slope and all that stuff
[14:00:41] <_methods> all kinds of stuff i don't know how to use
[14:01:06] <_methods> has lots of twisty knobs and switches and stuff
[14:01:34] <CaptHindsight> http://chicago.craigslist.org/chc/for/5646086776.html more knobs than you can shake a stick at
[14:02:00] <_methods> i saw that on ebay
[14:02:06] <_methods> for $350
[14:02:08] <_methods> lol
[14:02:34] <Sync> yeah somebody is trying to make a buck
[14:02:39] <Sync> tbh, they are not bad units
[14:03:34] <CaptHindsight> great for light stuff
[14:03:43] <BeachBumPete> All those knobs are VERY useful if you have them believe it
[14:03:50] <CaptHindsight> the accessories are cheapo
[14:03:58] <JT-Shop> http://gnipsel.com/images/equipment-shed/big-dig-11.jpg
[14:04:28] <Sync> CaptHindsight: I've been running mine at 200A all day, if the ambient is not super hot they keep up with it very well
[14:05:00] <CaptHindsight> most knobs per sq in of any welder http://www.ebay.com/itm/Super200P-220V-Inverter-Welder-AC-DC-Aluminium-Pulse-TIG-MMA-CUT-Welding-Machine-/361430825016
[14:05:08] <BeachBumPete> really?? 200 amps all day?
[14:05:16] <JT-Shop> Pete did you see the blast cabinet? http://gnipsel.com/images/blast-cabinet/Blast%20Cabinet%2040.JPG
[14:05:19] <Sync> yup BeachBumPete
[14:05:30] <Sync> I have a water cooled torch on it tho
[14:06:19] <BeachBumPete> I doubt my Ltec would be happy running 200 amps all day so that is quite impressive for a chinese machine
[14:06:19] <CaptHindsight> is that the 1000 year blast cabinet made from 1/3 plate? :)
[14:06:25] <CaptHindsight> 1/4"
[14:06:47] <Sync> well, they are built actually quite conservatively inside
[14:06:48] <Sync> so eh
[14:06:54] <CaptHindsight> the IGBT's are very low resistance
[14:06:56] <BeachBumPete> JT-Shop no I have not but I don't really follow your site too much :D
[14:07:01] <CaptHindsight> so very little heat
[14:07:05] <Sync> CaptHindsight: pls.
[14:07:17] <CaptHindsight> it's the cheap torch that needs the cooling
[14:07:31] <Sync> > igbt
[14:07:34] <Sync> > resistance
[14:08:15] <BeachBumPete> JT-Shop Funny that looks very nice but I GAVE away a perfectly working blast cabinet I made in Tennessee that was built from MDF and plastic windows :D
[14:09:23] <_methods> well i can't wait to try the dynasty out to compare against the ltec
[14:13:17] <JT-Shop> most is made from 11ga and the doors are 12ga
[14:14:20] <CaptHindsight> I bought one of those injection molded blast cabs from Enco
[14:14:35] <CaptHindsight> the siphon on the gun is lousy, but the rest is fine
[14:15:07] <BeachBumPete> yup mine was 3/4 MDF sheet and lasted for like ten years and will probably last another ten years for the guy I gave it to in tennessee because I did not have room to take it with me on the truck LOL
[14:20:06] <BeachBumPete> _methods http://i.imgur.com/08118XI.jpg ya sure you want to do that? :D
[14:20:21] <_methods> oh yeah
[14:20:37] <CaptHindsight> those pipes are all bent up
[14:20:51] <BeachBumPete> bent up?
[14:20:54] <Sync> I need to get a mandrel bender :/
[14:21:18] <_methods> i'm kinda space limited so the small size of the dynasty is a big plus
[14:21:35] <_methods> that ltec is takin up a lot of real estate
[14:22:00] <BeachBumPete> yeah but so will that bigass dual welder kart and bottle holder you are going to build ;)
[14:22:13] <_methods> hahah true
[14:22:25] <BeachBumPete> I'm just bustin yer chops man
[14:22:35] <BeachBumPete> I would like to have a Dynasty 200 myself
[14:22:44] <BeachBumPete> its a great machine by most accounts
[14:23:01] <_methods> i have no idea we don't have any here at the shop or any shop i've worked at
[14:23:07] <_methods> always been syncrowaves
[14:23:09] <BeachBumPete> I have what I have and it works well for me and has power to spare but I would sure enjoy some of the newer features to play with.
[14:23:37] <_methods> i know the syncrowaves at work have a much more stable arc than my ltec
[14:23:45] <_methods> but i can't complain
[14:23:47] <_methods> for $400
[14:24:10] <_methods> it was a steal
[14:24:24] <Sync> yeah I really like pulse for SS BeachBumPete
[14:24:25] <BeachBumPete> REALLY?? That is very surprising to hear
[14:24:47] <BeachBumPete> I have used synchrowaves at work and I could not tell any difference
[14:25:01] <BeachBumPete> and the Synchrowave is widely held as one of the best
[14:25:57] <_methods> oh yeah i can definitely tell a difference between my ltec and the syncrowaves
[14:26:11] <CaptHindsight> I thought that ESAB held the title as snobbyest welder
[14:26:16] <BeachBumPete> perhaps there is something wrong with your Ltec
[14:26:22] <_methods> it's possible
[14:26:35] <_methods> esab is the most worthless welder maybe
[14:26:37] <_methods> lol
[14:26:52] <BeachBumPete> if there is ANYTHING I can brag about on my machine is the smoothness of the arc...it does not have a lot of bells and whistles but it does have that
[14:27:00] <BeachBumPete> LOL Esab IS LTEC
[14:27:18] <_methods> no esab bought out ltec
[14:27:25] <_methods> ltec was linde
[14:27:31] <BeachBumPete> exactly
[14:27:33] <_methods> and linde was union carbide
[14:27:53] <BeachBumPete> they basically invented heliarc technology
[14:27:57] <_methods> yes
[14:29:22] <_methods> well i guess the ltec that made our machines got bought by linde
[14:29:28] <_methods> from union carbide
[14:30:14] <_methods> i think that's how it went down
[14:30:21] <_methods> but i don't remember exactly
[14:31:38] <Sync> iirc ltec always was ltec
[14:31:47] <Sync> they then got bought by UC
[14:31:52] <Sync> then UC sold their shit
[14:32:02] <Sync> and then ESAB bought them
[14:35:19] <_methods> http://www.netwelding.com/History_TIG_Welding.htm
[14:35:27] <_methods> no idea if any of that stuff is actually accurate
[14:35:31] <CaptHindsight> do any of you have problem getting your tanks filled or exchanged?
[14:35:43] <_methods> nah i just swap out at work
[14:36:19] <CaptHindsight> I found a supplier in Milwaukee that will take any tank I show up with for exchange
[14:36:32] <_methods> hehe
[14:36:43] <_methods> they don't care if it's inspected?
[14:36:44] <CaptHindsight> bought several 300's on craigslist
[14:37:13] <CaptHindsight> I had one a few months past the date and they still just swapped it out for one of theirs
[14:37:33] <CaptHindsight> 10 years + a few months
[14:37:54] <_methods> nice
[14:38:17] <CaptHindsight> airgas and similar all want you on a lease only for big tanks
[14:38:44] <_methods> national welders will usually let you swap without contract
[14:40:08] <BeachBumPete> I rented my tank in Tennessee for 5 years for like $250 and a fill was about a hundred bucks...
[14:40:22] <_methods> oh ouch
[14:40:24] <_methods> for nitrogen?
[14:40:36] <BeachBumPete> argon big tank
[14:40:48] <_methods> or yeah argon sorry
[14:41:02] <_methods> damn i think we pay $70 for argon
[14:41:08] <jdh> I pay $15/yr lease per bottle
[14:41:08] <Sync> I need to get me a nitrogen tank
[14:41:23] <Sync> purging ss with it is fine too and much cheaper than wasting argon
[14:41:51] <_methods> nitrogen we have a giant 20' tall tank lol
[14:41:54] <BeachBumPete> I just purge from the same argon bottle
[14:41:55] <_methods> liquid
[14:42:09] <BeachBumPete> dual reg
[14:42:13] <_methods> bulk ntirogen
[14:42:19] <_methods> laser is a nitrogen pig
[14:42:43] <_methods> been trying to talk the boss into getting a nitrogen generator so we can cut back on the bulk nitrogen
[14:42:55] <SpeedEvil> Nitrogen concentrator.
[14:42:57] <_methods> just use the nitrogen generator for purge and light metal
[14:43:04] <_methods> yes
[14:43:14] <_methods> concentrator lol
[14:43:21] <SpeedEvil> does nitrogen work ok as a shield gas for Al?
[14:43:33] <_methods> for laser?
[14:43:36] <BeachBumPete> its been like 3 months now since I struck an arc I am beginning to wonder If I remember how
[14:43:38] <_methods> or welding
[14:43:53] <Sync> yeah BeachBumPete so do I but nitrogen is cheaper for me to refill
[14:43:59] <SpeedEvil> Oops
[14:44:00] <SpeedEvil> nvm
[14:44:10] <Sync> so it'd be cheaper to run two tanks
[14:45:01] <BeachBumPete> actually if I used more argon I would have gotten a better price apparently but I did not use too much until I started working for the race shop guys and then they got their own account
[14:47:10] <_methods> https://www.youtube.com/watch?v=C29VyUYJg8s
[14:47:24] <_methods> is life that really that bad for people that don't watch game of thrones lol
[14:47:45] <jdh> I have a friend with a busy account that I use. relatively cheap lease and fills
[14:48:20] <BeachBumPete> never watched it myself
[14:48:21] <CaptHindsight> helium is a real pricey way to go foe shielding gas, but it works great for overhead welds
[14:49:00] <SpeedEvil> vacuum is free
[14:49:06] <BeachBumPete> I thought it was more for getting a lot hotter arc...
[14:49:09] <CaptHindsight> but it sucks
[14:49:21] <andypugh> The books are better. :-)
[14:50:10] <_methods> the books that will never be finished lol
[14:51:14] <andypugh> Real history never finishes. Why should fake history?
[14:52:47] <_methods> i'm sure the fat bastard will die before he does finish them so........there's that
[14:54:51] <andypugh> I wonder if this will sell? It’s cheap at the moment: http://www.ebay.co.uk/itm/holbrook-lathe-/331894203047?&_trksid=p2056016.l4276
[14:55:08] <_methods> fixxer upper
[14:55:18] <_methods> on pipes already hehe
[14:56:38] <andypugh> Chepaer than the other one: http://www.ebay.co.uk/itm/301988141155
[14:57:13] <_methods> and it doesn't come with teh pipes or the string
[14:57:40] <andypugh> I definitely don’t need either. But they are good lathes.
[14:58:30] <_methods> yeah they don't make them like that anymore
[15:05:30] <andypugh> Partly beause there is no need.
[15:06:26] <Sync> I probably would not get any of them
[15:06:36] <Sync> they look like they have been used well
[15:07:05] <andypugh> One neat thing about the Holbrooks is that they have a double-dovetail cross slide. This gives you a quick-retract for threading that goes back to the same setting. (it’s also part of the taper-turning setup, so you can taper-turn and still feed with the cross-slide rather than the compound)
[15:08:09] <andypugh> http://www.budgetmachinery.co.uk/newsite/data/bm/lathes/pictures/holbrookb21/holbrookb21b.jpg
[15:09:13] <Sync> stiffness--
[15:12:00] <Denkishi> OH, so what would be an inexpensive way to upgrade the controller on a TRAK DPM CNC knee mill? I want to utilize the current AC servo motors as well :)
[15:13:47] <Sync> that depends on the servo drives
[15:15:57] <andypugh> <pedant> I am not sure it is technically a knee-mill, as the head seems to be the bit that moves for Z
[15:16:27] <Denkishi> andypugh, yeah, true.
[15:16:34] <Denkishi> Sync, how to mean?
[15:16:37] <cradek> can you tell us what drives, what interface do they have, what feedback devices?
[15:16:39] <Denkishi> how do you*
[15:16:43] <andypugh> It looks rather likely to be using analogue-controlled drives.
[15:18:04] <Denkishi> 220v spindle, 110v axis drives....
[15:18:30] <Denkishi> I have all the manuals in front of me, just not sure where the info requested is
[15:18:57] <andypugh> What are the wires between the drives and the motors labelled as?
[15:20:51] <Denkishi> http://i.imgur.com/N6D0mA3.jpg
[15:21:00] <andypugh> And between the controller and drives? Any wires straight from the motors to the controller?
[15:21:28] <Denkishi> I need to head out, will hop back on at home ..
[15:21:52] <andypugh> Hmm, not the most helpful of all possible diagrams
[15:22:13] <Sync> oh wow andypugh mark higgins at it again on the iom
[15:32:15] <Loetmichel> brrr. i hate the smb.config. anyone knows a nice little browserbased gui for configuring a stock ubuntu SMB server?
[15:43:08] <cpresser> webmin^^
[15:45:16] <Loetmichel> cpresser: webmin is "not recommended" as far as i know
[15:50:31] <Denkishi> OK, here is the other one: http://i.imgur.com/5eF37Ep.jpg
[15:51:40] <_methods> Loetmichel: i've never used it but i think gtksamba will do that
[15:51:59] <_methods> not web based though
[15:52:44] <Sync> Denkishi: a picture of the cabinet would have been more useful
[15:53:00] <Loetmichel> _methods: no gui on that (fresh installed) ubuntu server
[15:53:07] <_methods> ah
[15:53:17] <_methods> yeah i don't know of any browser based ones
[15:54:05] <Denkishi> And one more: http://i.imgur.com/Cx6Uxqd.jpg
[15:54:45] <_methods> you just want a web based smb.conf generator right?
[15:55:00] <Denkishi> Sync, what are you trying to know? It's a single cable bundle to heach motor. The controller is essentially a 386 computer :/
[15:55:22] <Sync> they will have dedicated servodrives
[15:55:24] <_methods> you could use swat i guess
[15:55:30] <Denkishi> A Fanuc 6 controller iirc
[15:55:36] <_methods> http://ubuntuserverguide.com/2012/10/how-to-install-and-configure-swat-samba-web-administration-tool-on-ubuntu-server-12-04.html
[15:57:12] <andypugh> Denkishi: We want to know what signals are on the cables in the bundle
[15:57:38] <Sync> and if possible you can retain the original drives
[15:57:48] <Denkishi> andypugh, ok, i had a feeling you were gonna say that.
[15:58:14] <andypugh> A pinout of the controller (DB37 and DB25) would be ideal.
[15:58:18] <Denkishi> Sync, that would be ideal. I'll be back to work on Thursday, I'll take a gander then.
[15:59:00] <Denkishi> er, technically I am supossed to be able to hook it to a PC and do DNC, but I can't seem to get it to work .
[16:00:40] <Denkishi> The servo driver for each motor is in the casing of the motor..
[16:00:46] <Denkishi> (Just read that lol)
[16:01:23] <Sync> doubtful
[16:02:02] <Denkishi> Er, just read that in the manual. And makes sense given the build of the motors...
[16:02:06] <enleth> that seems to be rare for big servos to have integrated drives, but they do exist
[16:02:34] <Sync> probably not in that age
[16:02:36] <andypugh> http://www.ebay.com/itm/Southwestern-Industries-Trak-DPM-parts-x-and-y-servo-motors-/281919259120?nma=true&si=Fs99ZkUhbpJ2dEh6c6YSD8tuMfU%253D&orig_cvip=true&rt=nc&_trksid=p2047675.l2557
[16:02:44] <andypugh> Looks like they are
[16:02:52] <cradek> retrofit might be super easy if you already have connnectors and just need to make a different box and plug them in
[16:02:59] <enleth> Denkishi: if the control/feedback signals are something sane (+/-10V and quadrature encoder signals), and the motors/drives are appropriately sized, you are lucky, less work for you
[16:03:03] <Sync> interesting
[16:03:14] <cradek> wiring is always the hard and messy part
[16:03:24] <Denkishi> Obviously another drawing but... : http://i.imgur.com/0oMHP43.jpg
[16:04:16] <Sync> well, good luck then
[16:04:16] <Denkishi> I believe the signal will be 5v and the controll 115. Given this drawing: http://denkishi.imgur.com/all/
[16:04:21] <Denkishi> whoops
[16:04:30] <Denkishi> http://i.imgur.com/N6D0mA3.jpg
[16:05:00] <Denkishi> So back to my original question, what should I be looking at for an alternative controller?
[16:05:00] <andypugh> I think X-sensor might be home/limit switch
[16:05:12] <enleth> cradek: tell me about it, I finally decided I have had enough disconnecting and connecting the motors on my mill for testing, with the armored cable being extremely heavy and difficult to hold up under the motor while securing the wires in a terminal block - I'd rather shell out the money for those nice sealed circular connectors than fiddle with that crap
[16:05:31] <andypugh> Denkishi: Do you expct any answe than “LinuxCNC” to be the response here?
[16:05:55] <Denkishi> andypugh, good point. No limit switched, but there is a "roller" that senses the position.
[16:06:03] <andypugh> enleth: Mouser have the M20 cheaper than anyone else
[16:06:24] <Denkishi> andypugh, lol, so will a PI work? lol
[16:06:53] <enleth> Denkishi: if you want it done properly, a set of Mesa 5i25 (or 6i25) and 7i77 with LinuxCNC is the default option for your type of machine I guess
[16:07:28] <andypugh> A Pi is probably more powerful than the original controller, and has much better graphics. But the real-time thread latency isn’t particularly good, nor is there a great range of hardware interfaces for CNC.
[16:07:38] <enleth> Denkishi: but you need to figure out the speed control signal for the servos, this is not "5V" because it needs to be analog - unless there's some kind of digital bus in there
[16:07:42] <andypugh> (Or didn’t you expect a serious answer :-)
[16:08:16] <Denkishi> andypugh, that makes perfect sense. Thank you
[16:08:48] <cradek> yes the best answer is a suitable PC motherboard with PCI or PCI-e slots, and the appropriate mesa fpga cards and interfaces
[16:09:01] <andypugh> Denkishi: You probably want a Mini-ATX Intel motherboard with a PCI slot and a Mesa card.
[16:09:03] <cradek> "appropriate" depends on what you find out about the interface of your servo drives
[16:09:20] <enleth> Denkishi: if you're super lucky, it's a +/-10V signal, which is an industry standard of sorts for servo speed signaling. Otherwise it might be 4-20mA and a speed setting signal, or something even weirder
[16:09:30] <cradek> touch screen, jogwheel, a few buttons, linuxcnc with touchy user interface
[16:09:43] <andypugh> There are some nice motherbpards that only need 12V power, which is saves trouble in a CNC installation.
[16:09:48] <Denkishi> Well what I do know at the moment is that it's currently a Fanuc 6 controller. That's about it :P
[16:10:04] <enleth> Denkishi: so try to find a datasheet for those motors
[16:10:16] <enleth> Denkishi: or a datasheet for the controller, detailing the servo control interface
[16:10:36] <enleth> and hope neither of those is a customized version with a non-standard interface
[16:11:29] <Denkishi> It's a Southwestern Industries Trak DPM with an A.G.E. 3
[16:11:42] <Denkishi> Early/mid 90
[16:11:45] <Denkishi> 's I think
[16:13:35] <andypugh> Have you poked around their web site, they seem to have a lot of stuff online
[16:14:14] <andypugh> http://www.southwesternindustries.com/docs/knee-mills#service-manuals
[16:15:10] <Denkishi> Well, I have the Saftey, Installation, Maintenance, Service, & Parts list manual, the Programming, and the interface manual
[16:15:44] <enleth> yeah, so before we can help you *any* further, you need to figure out the servo interface and encoder interface
[16:16:04] <enleth> detailed electrical specs of those are required to match new control hardware
[16:19:12] <andypugh> They seem to be brushed DC servos, by the way.
[16:21:40] <andypugh> Of course, you could consider asking the manufacturer for a controller upgrade, if your pockets are deep
[16:22:27] <Denkishi> andypugh, that's one thing I was wondering. But the 115v running to them threw me off
[16:22:52] <Denkishi> andypugh, and yeah, doubt that would happen lol. Hence the search for a cheaper alternative.
[16:22:53] <andypugh> It’s 115V to the drive, and the drive contains a rectifier and H-bridge
[16:23:12] <Denkishi> Ahh, yeah that would make more sense.
[16:24:24] <andypugh> I had a look through the retrofit manual and they are very coy about the motor pinout.
[16:24:34] <andypugh> Afre you any good with an oscilloscope?
[16:25:30] <Denkishi> Though I wouldn't need a special probe to check if it's a 4-20ma signal vs +/- 10V?
[16:25:40] <enleth> if their tech support is anything like Heidenhain's, they might be willing to answer a question about it
[16:25:41] <andypugh> I would expect to see three encoder channels out of the back of the motor, and 2 power leads to the motor.
[16:25:55] <enleth> it's not like this machine is a cutting edge model full of trade secrets now
[16:26:17] <andypugh> And then probably a +/-10v speed command on a pair of wires to the drive.
[16:26:34] <Denkishi> Well if our controller definitely did die, I may as them about it.
[16:26:43] <enleth> and a couple misc signals like enable/inhibit
[16:27:06] <Denkishi> Had a brown-out today and now it will beep like it's turning on, but no output on the screen.
[16:27:44] <enleth> Denkishi: call them and say you couldn't find a detailed motor connector pinout in the docs and you need it to bring the machine back to life, you might get lucky
[16:29:00] <andypugh> If it’s +/-10v then you need a PC, a monitor and something like this: http://store.mesanet.com/index.php?route=product/product&path=83_84&product_id=214
[16:29:27] <andypugh> Call it $500 after adding in all the $1 parts.
[16:33:48] <andypugh> This is wierd. I had one of these running my electric clutches and brake: http://www.ebay.co.uk/itm/231742556113
[16:35:00] <andypugh> It worked fine until I forgot an insulating washer on a clutch brush and killed a channel. So I bought another. But that doesn’t work. The SSRs get hot and then fail to turn off. This is bad when it’s the brake
[16:35:49] <andypugh> This is running at 24V 1.5A. Rated 5A 220V
[16:38:04] <andypugh> I suspect that the second one isn’t actually using “real” relays
[16:39:19] <Sync> hm
[16:41:33] <andypugh> I feel an autopsy coming on :-)
[16:42:11] <Deejay> gn8
[16:43:29] <enleth> >The moving parts of a machine are those parts of it that move.[citation needed]
[16:43:38] <enleth> Wikipedia, never ceases to amaze.
[16:43:54] <Sync> oh wow
[16:44:21] <roycroft> some people need that level of explanation
[16:44:33] <roycroft> to some, the obvious isn't
[16:45:11] <enleth> If being stupid were a misdemeanor, someone would be due a citation indeed.
[16:53:41] <andypugh> enleth: Probably someone’s idea of a joke.
[16:54:14] <KreAture> lol enleth
[16:55:27] <KreAture> My fav wikipedia article: https://en.wikipedia.org/wiki/Wikipedia:List_of_really,_really,_really_stupid_article_ideas_that_you_really,_really,_really_should_not_create
[16:56:35] <KreAture> I have a strong urge to update it though, I feel I need to update the cat image to a better one...
[16:56:43] <KreAture> That is, the first pic
[16:56:49] <andypugh> enleth: See the [citation needed] here: https://what-if.xkcd.com/115/
[16:58:37] <enleth> yeah, probably
[17:02:56] <KreAture> My biggest grievence with citations is when they block new data or information
[17:03:58] <KreAture> somneone has to publish, but publishing shouldn't be paywalled in those peer reviewed magazines
[17:04:12] <KreAture> It's time we get modern
[17:08:03] <PCW_> andypugh : do you have a flyback diode across the clutch?
[17:13:20] <andypugh> PCW_: No. Hmmm
[17:13:59] <PCW_> probably need one for clutch/brake
[17:14:35] <andypugh> Yes, I guess so. I will see if I can add some, somehow.
[17:14:39] <PCW_> (too many Joules for the transistor to dissipate)
[17:15:05] <andypugh> Though the dead channel does work until it gets warm.
[17:16:12] <PCW_> yeah, secondary breakdown (little overheated spots in the silicon)
[17:18:03] <PCW_> the diode makes the clutch coil dissipate the 1/2LI^2 energy, not the transistor
[17:21:02] <andypugh> I found 4 small diodes. Can’t make sense of the markings
[17:21:12] <andypugh> Forward voltage 0.5V
[17:22:21] <PCW_> a 1n400X type diode should be fine
[17:22:22] <andypugh> (Backwards-Z)TTH 110 814 mean anything?
[17:22:43] <PCW_> not to me
[17:26:45] <PCW_> I thought everyone had at least a few 1N4007s around....
[17:27:38] <andypugh> Looks to be a 1000V 1A rectifier diode made in 2014
[17:27:58] <BeachBumPete> I don't :D
[17:28:39] <PCW_> OK a 1A rectiifer will work fine
[17:29:52] <andypugh> I have some 40A 1000A ones, but they would be harder to fit under the PCB :-)
[17:30:40] <andypugh> “The STTH110, which is using ST ultrafast high voltage planar technology, is especially suited for free-wheeling, clamping, snubbering,”
[17:30:46] <andypugh> Sounds good
[17:47:42] <CaptHindsight> https://imagebin.ca/v/2mGQYRevoc7c not even ACME
[17:48:13] <CaptHindsight> https://imagebin.ca/v/2mGQlFJkCk8g
[17:48:35] <CaptHindsight> expecting a nema17 stepper driving this when I open it
[17:49:18] <CaptHindsight> http://us.xyzprinting.com/us_en/Product/Nobel-1.0 why it's only ~$1k US
[17:49:50] <Sync> doesn't really have to be a an acme screw
[17:52:19] <CaptHindsight> lots of injection molded parts, they spent a bit on tooling
[17:53:39] <CaptHindsight> not sure why 3d systems didn't file suit against these guys
[17:53:48] <CaptHindsight> just formlabs
[18:09:25] <Polymorphism> saw some nice machines today
[18:09:39] <Polymorphism> cnc lathe, haas vf2, wire EDM, broach, etc
[18:09:56] <Polymorphism> + a lot more
[18:10:27] <Polymorphism> aerospace factory tour
[18:12:39] <Polymorphism> ah yes also lapping machines + some kind of cnc grinder that honed the wheel before each operation
[18:13:00] <Polymorphism> all in all a fascinating and informative experience
[18:13:18] <Sync> dressing is pretty common with cnc grinders
[18:13:30] <Sync> as they have to know the wheel diameter to solve for their path
[18:15:07] <Polymorphism> yeah dressing, thats what the guy operating it called it. I'd never seen a machine like that
[18:20:21] <jdh> making chips yet?
[18:21:06] <Polymorphism> waiting on replacement ballscrew =\
[18:21:18] <Polymorphism> been working on the enclosure though
[18:21:23] <Polymorphism> (for the electronics)
[18:53:53] <JT-Shop> Tom_itx: no traces of get windoze 10 app
[18:54:15] <JT-Shop> seems to have worked
[18:55:51] <KreAture> so what kind of control do ppl here use? Lots of geckos I assume ?
[18:56:23] <KreAture> I have 5mm/turn screws so for me anything beyond 1/16 step is insanely slow hehe
[19:02:24] <andypugh> KreAture: I think many of us don’t use steppers at all.
[19:03:43] <andypugh> I am about to retire my stepper lathe. I have a servo lathe and a servo mill (both using resolvers)
[19:04:17] <andypugh> I just remembered that Gecko make servo drives too.
[19:04:22] <Frank_12> im so happy, my 7i76 combo already shipped, mesa4ever lol
[19:07:28] <alex4nder> Frank_12: what're you hooking your 7i76 up to?
[19:17:43] <KreAture> anoooh servo
[19:18:23] <KreAture> Frank_12 I try to keep the system on the lowcost side
[19:18:30] <KreAture> I guess I cracked with the beebox though
[19:18:49] <KreAture> http://kreature.org/projects/cnc/build_10.jpg
[19:18:52] <KreAture> hehe
[19:19:20] <Frank_12> a cnc router kreature,
[19:19:45] <KreAture> Iy cuts ok and I had fun building it
[19:19:46] <Frank_12> oh i think i've seen a pic of that one before
[19:19:50] <KreAture> yeh
[19:20:07] <KreAture> the box for it was supposed to use a bbb but it was just so laggy
[19:20:08] <KreAture> http://kreature.org/projects/cnc/controlsystem/controlbox_2_s.jpg
[19:20:17] <KreAture> so now I want to replace the bbb for the beebox
[19:20:30] <KreAture> atleast that drives the gui smooth as silk
[19:20:55] <KreAture> The controlbox still needs the filter holder and the fan setup as well as holes for the air hehe
[19:20:59] <Frank_12> well i cant speak from experience..
[19:21:08] <KreAture> didn't want to add that till I knew everything else was nailed down
[19:21:16] <Frank_12> but i've read a lot and mesa seems quite nice stuff
[19:21:29] <KreAture> I just have a hard time swallowing the price
[19:21:32] <Frank_12> mach/linux/chinesse controllers
[19:22:10] <KreAture> hell no if I will use mach
[19:22:18] <KreAture> linuxcnc if is so much nicer
[19:23:38] <Sync> KreAture: if you had not bought the BBB you almost would have had the cost in for a mesa card
[19:24:04] <KreAture> Sync I borrowed the bbb to qualify it
[19:24:23] <Sync> well then you have the money left over to buy a mesa card
[19:24:41] <KreAture> I almost majored in reprogrammable hardware btw
[19:24:48] <KreAture> ended up doing motor control instead
[19:24:59] <KreAture> I am glad too, we fired all the fpga programmers at my workplace
[19:25:09] <KreAture> simply no work for them from our customers
[19:25:16] <KreAture> we did help them to get other jobs though
[19:25:47] <KreAture> fpga to be programmed for the exact io control you need is an awsome solution, it's just a tad overboard
[19:26:15] <KreAture> and the fpgas used on those mesa boards are not cheap
[19:26:38] <KreAture> all I really need is a pcie bridge controller chip with lpt and that is $6
[19:27:07] <KreAture> This is after all a hobbymachine
[19:27:13] <malcom2073> They fpgas used on the mesa boards weren't cheap years ago, they're fairly cheap now
[19:27:18] <KreAture> (maby I went a tad overboard on the build, but still a hobbymachine)
[19:27:25] <KreAture> "fairly"
[19:27:29] <KreAture> but yes prices have come down
[19:27:39] <malcom2073> fairly being $20 iirc
[19:28:03] <KreAture> 200k gates is not a small chip but not a insanely huge one either, still...
[19:28:18] <KreAture> malcom2073 boards containing a $20 chip quickly cost 200 to buy
[19:28:18] <malcom2073> I thought about getting a chinese breakout board for like $25... but all the peripherals would drive the price up to match a normal mesa heh
[19:28:40] <malcom2073> KreAture: But in comparison to modern fpga's, it's damn cheap :-P
[19:28:49] <KreAture> hehe ok
[19:28:57] <KreAture> toys have gotten cheaper
[19:28:59] <KreAture> :)
[19:29:02] <KreAture> we are lucky
[19:29:05] <malcom2073> Very fortunatly for hobbiests!
[19:29:44] <Sync> KreAture: it's not really overboard imho, to me a parallelport is just limiting my abilities
[19:29:58] <malcom2073> I'ma have to get a mesa at some point here, I have some servos I gotta drive
[19:29:58] <KreAture> Sync you probably have a large proper mill
[19:30:12] <KreAture> and yes for servo drive and such I get it
[19:30:37] <KreAture> I just plod along to cut a mailbox front with a engraved moose on it
[19:30:38] <KreAture> hehe
[19:30:43] <KreAture> (my next project)
[19:32:03] <Sync> well, in the end the mesa card is just a serial port for me
[19:33:04] <KreAture> ahh so you do not use the pcie cards ?
[19:33:09] <KreAture> Then it definately gets cheaper
[19:34:26] <KreAture> or do you go the 5125+7i76 route
[19:34:39] <Frank_12> 7i76 not for servos
[19:34:49] <Frank_12> 7i77 for analog if im not mistaken
[19:35:35] <KreAture> servos can have digital feedbacks though ?
[19:35:42] <KreAture> but you ment analog powerdriver ?
[19:35:53] <Sync> KreAture: I use one of the ethernet cards
[19:35:53] <KreAture> in that case yes I see what you mean
[19:35:55] <Sync> and just that
[19:36:11] <KreAture> ahh
[19:36:17] <KreAture> and then run on a diff pc ?
[19:36:28] <KreAture> I want this to be standalone thus the bbb or beebox
[19:36:47] <KreAture> Ppl need to be able to plod down to the workshop with a file to run it
[19:37:00] <Sync> yeah why not
[19:37:01] <KreAture> I plan on having a workstation there so code can be edited or regenerated etc
[19:37:06] <Sync> my computer is inside the cabinet as well
[19:37:30] <KreAture> just want to seperate em so the guy running cnc does not block the guy preparing a job
[19:37:48] <KreAture> The one for the cad is a insane powerhouse type thing
[19:37:54] <KreAture> dual xenon cpus etc
[19:38:06] <KreAture> err xeon
[19:38:08] <KreAture> lol
[19:38:08] <Frank_12> i mean yeah, im using servos with the 7i76 but in a step/dir mode, i was wrong
[19:38:31] <Frank_12> but 7i76 wont do analog servos
[19:38:36] <KreAture> true
[19:38:53] <KreAture> don't you still need amplifiers to use the 77 with analog servo ?
[19:39:08] <KreAture> It delivers analog signal but does not power the servo does it ?
[19:39:21] <Frank_12> exactly
[19:39:25] <Frank_12> i call them drivers
[19:39:26] <Frank_12> hehe
[19:39:32] <KreAture> well I like my box
[19:39:41] <KreAture> each of the china drivers have opto
[19:39:49] <KreAture> They were really shitty assembled
[19:40:13] <KreAture> but the actual hw is good, so I just cleaned it up, resoldered some shorts etc and added thermal paste before fixing the heatsink attachment
[19:40:25] <KreAture> they all perform perfectly and I tested em over 4.5 amps
[19:40:29] <KreAture> I only need 3
[19:40:53] <KreAture> I paid $40 for 5 pcs
[19:41:23] <KreAture> I checked the choice of optos and they were good
[19:41:26] <malcom2073> My dad jsut had one of the chinese 4 axis stepper drivers go pop :/
[19:41:39] <malcom2073> Apparently it's a roll of the dice. They either work great for a while, or pop after a small amount of usage
[19:41:41] <Frank_12> auch
[19:41:42] <KreAture> not surprised with how shitty they were assembled
[19:41:56] <KreAture> These would have died had I used em as they came
[19:42:04] <Frank_12> well my servos are panasonic made in china....
[19:47:02] <KreAture> http://kreature.org/projects/cnc/stepdrives/DSC_0681.JPG
[19:47:07] <KreAture> I just had to find the pics
[19:47:16] <KreAture> Frank_12 look at those heatsinks
[19:47:17] <KreAture> hehe
[19:47:29] <KreAture> especially number 2 from left
[19:47:44] <KreAture> see how it hangs on the switchblock ?
[19:48:03] <Frank_12> in an angle?
[19:48:22] <KreAture> They didn't have proper contact with chip and bent the cards due to the block being too close
[19:48:28] <KreAture> http://kreature.org/projects/cnc/stepdrives/DSC_0686.JPG
[19:48:30] <KreAture> fixed
[19:48:49] <KreAture> They had other issues too
[19:48:53] <KreAture> like this one http://kreature.org/projects/cnc/stepdrives/DSC_0682.JPG
[19:49:42] <KreAture> I disassembled all and inspected
[19:49:46] <KreAture> most needed touchups
[19:50:00] <malcom2073> Yeah the 6600's I got were about the same
[19:50:14] <malcom2073> On one, the heatsink mounting screw actually had hit a resistor and chipped it
[19:50:15] <KreAture> Then I added paste and reattached the modified sinks
[19:50:21] <KreAture> lol
[19:50:23] <KreAture> nice
[19:50:27] <Frank_12> well, good thing u know the stuff, i would electrocute myself haha
[19:50:51] <KreAture> They all test fine now though
[19:51:00] <KreAture> I am glad i did not test em before checking
[19:51:12] <KreAture> atleast two of em would have gone POOF immediately
[19:53:09] <KreAture> will be interesting to see how the BeeBox N3150 performs when running the cnc though, can't wait to get the mPCIe board for it
[19:53:19] <KreAture> if it is a success I may do a 2 port board
[19:53:38] <KreAture> There appears to be room, and I don't see any available online so it may be usefull
[19:54:00] <KreAture> Ofcource it could easily have a fpga instead but then I'd have to do more work
[19:54:01] <KreAture> hehe
[19:55:00] * KreAture goes back to dreaming of sheep
