#linuxcnc | Logs for 2016-10-26

[00:20:56] <mikeh__> maybe a crazy question, but what port does the nml "server" live on in linuxcnc?
[00:21:09] <mikeh__> or am i completely misunderstanding how nml works?
[01:34:33] <Crom> yeah... or I could see if I can get my weller going for a day or three again...
[01:35:31] <Crom> CaptHindsight, ala that steampunk book... with the mechanical pixels screens?
[01:41:12] <renesis> the difference engine? its by sterling and gibson
[01:41:37] <renesis> i dont remember what the screens were called
[01:43:04] <renesis> kinotropes
[02:31:00] <Crom> that's it been forever since I read it
[02:31:47] <Crom> at least '92
[02:43:16] <pink_vampire> why i go with the g0704 and not a router based machine https://youtu.be/TSTThLM8s8o?t=5m50s
[03:25:38] <archivist> pink_vampire, I can show similar bending on that type of mill
[03:26:13] <archivist> and other forms of error
[03:31:12] <pink_vampire> archivist: what do you mean?
[03:44:42] <archivist> pink_vampire, all machines flex like that gantry, just the amount varies
[03:46:24] <pink_vampire> i know, but here you can see few milliliters of flex, not microns that you need a dial indicator to find them.
[03:52:13] <Valen> pink_vampire: the amount doesn't matter so much when you consider the design load
[03:52:50] <Valen> if you put 20kg of force on something designed to handle .1kg
[03:53:45] <archivist> a router cute the wood before the frame can bend (mass of spindle assembly)
[03:53:56] <archivist> cuts
[03:54:20] <pink_vampire> what about metals..
[03:55:12] <archivist> as a metal cut is generally slower there is time for the machine to flex, so it had better be rigid enough for the load
[03:55:39] <Valen> to me what's more important is backlash if you push it does it come back to 0
[03:55:45] <renesis> thupthupthupthup
[03:56:03] <Valen> you can factor in flex with finsish passes, if it doesn't get back to 0 then you have a problem
[03:56:22] <renesis> valen: you have to load the machine enough for backlash compensation to work
[03:56:48] <Valen> I say backlash, I don't actually mean backlash, like you get in a screw
[03:57:25] <Valen> I mean when you push on the bearings to the side on X (push the X axis in the Y direction) does it spring back or stay over
[03:57:39] <renesis> my machine is little so sometimes the ways arent enough friction to move it all the way to the other side of the nut, so I have to load it down somehow when measuring backlash, and if cuts are too light it wont error as much so compensation is off
[03:58:00] <Valen> put a second nut on with a spring
[03:58:02] <renesis> valen: dunno that sounds like variable backlash to me
[03:58:28] <renesis> i have a clamped brass nut for anti-backlash, so bearing play isnt much diff
[03:58:38] <renesis> no springs
[03:58:39] <Valen> if you can compensate for it with backlash comp then it's "fine" this is a problem with the ways and joints and other bits and bobs
[03:58:58] <Valen> those nuts with a cut in them are crappy at backlash tbh
[03:59:10] <renesis> all pretty relative
[03:59:12] <Valen> they put lots of friction on with little effect at least in the ones I've used
[03:59:17] <archivist> lean on table see if the ways allow rotation :)
[03:59:24] <renesis> i seem to have a lot better backlash performance than other people with small mills
[03:59:26] <Valen> you might have a better one than I have
[03:59:53] <Valen> we replaced all the acme screws with ballscrews then added belville washers between a set of ball nuts to take out the backlash
[04:00:06] <Valen> something similar would work with acme at the expense of friction
[04:00:20] <renesis> shrug, its a threaded block with a peg and a slit, two clamp screws and a lock screw
[04:00:29] <renesis> and i dont have acme screws
[04:00:38] <renesis> taigs use standard threads
[05:11:22] <pink_vampire> https://www.youtube.com/watch?v=7_YFMXEFvXg
[05:12:41] <XXCoder> hey
[05:13:07] <pink_vampire> XXCoder: hii
[05:13:15] <XXCoder> whats up
[05:14:45] <pink_vampire> wiring
[05:16:36] <XXCoder> your machine?
[05:16:49] <pink_vampire> yes
[05:18:03] <pink_vampire> i'm working on the pilot devices
[05:18:12] <XXCoder> pilot?
[05:18:26] <pink_vampire> https://www.google.com/search?q=pilot+devices&safe=off&biw=1600&bih=1040&source=lnms&tbm=isch&sa=X&ved=0ahUKEwi0grzjmPjPAhXMCD4KHdAxCOgQ_AUICSgC
[05:18:53] <XXCoder> ah indictor status lights and buttons eh
[05:19:12] <pink_vampire> correct
[05:21:24] <XXCoder> nice
[05:21:49] <XXCoder> I want to use my WALK/HAND walk sign as indictor heh
[05:36:35] <pink_vampire> WALK/HAND walk ???????????
[05:36:53] <XXCoder> yeah
[05:36:59] <pink_vampire> pic?
[05:37:01] <XXCoder> the road crossing sign for walking
[05:37:26] <pink_vampire> why do you have stuff like that?
[05:37:43] <XXCoder> https://community.tradeking.com/upload/0001/3630/walk_dont_walk_sign.jpg omwthng like that
[05:37:46] <XXCoder> yeah dunno LOL
[05:39:12] <pink_vampire> lol
[05:39:19] <pink_vampire> you are crazy
[05:39:27] <XXCoder> i boiught it from electrics recycle center
[05:39:28] <XXCoder> $10
[05:39:38] <XXCoder> goverment probably paid $200 for it or something
[05:39:44] <pink_vampire> it is very cool
[05:39:44] <XXCoder> it was used
[05:40:00] <pink_vampire> but crazy
[05:40:13] <pink_vampire> in a good way
[05:40:50] <XXCoder> lol it would be good if i was good on electrics
[05:41:09] <pink_vampire> it is led?
[05:41:18] <XXCoder> yeah
[05:41:25] <XXCoder> unfortunately hand is half working
[05:41:37] <XXCoder> probably one led got burnt or something
[05:43:38] <pink_vampire> you cam get leds very cheap on ebay
[05:44:00] <pink_vampire> and also 330 ohm resistors
[05:44:30] <Deejay> moin
[05:44:45] <XXCoder> problem is finding out what is broken heh
[05:44:54] <pink_vampire> use resistor for each led and this way it will work from 5 vols, and last even if one led will die
[05:45:14] <pink_vampire> just rebuild it
[05:45:24] <XXCoder> can do it if I knew more
[05:45:46] <pink_vampire> very simple
[05:46:27] <pink_vampire> (+)------vvvvvv--------|>|--------- (-)
[05:46:50] <XXCoder> yeah
[05:46:53] <pink_vampire> repeat times the leds
[05:47:06] <XXCoder> im talking about entire thing though, capactors may be blown for example
[05:47:25] <pink_vampire> what capacitors
[05:47:34] <pink_vampire> just leds
[05:47:50] <XXCoder> its powered from 120v
[05:47:58] <XXCoder> so theres circuit to convert and stuff
[05:48:20] <pink_vampire> i see what you mean
[05:48:49] <jthornton> morning
[05:49:01] <XXCoder> hey jt
[05:49:05] <pink_vampire> morning jthornton
[05:50:23] <XXCoder> https://www.youtube.com/watch?v=GFgicL7ukUM
[05:50:27] <XXCoder> my room
[05:51:59] <jthornton> that hurts my eyes lol
[05:52:05] <pink_vampire> XXCoder: you want it to be?
[05:52:14] <XXCoder> heh yeah imange trying to sleep in that danged room jeez
[05:52:19] <XXCoder> pink hell no
[05:52:37] <jthornton> out comes a pistol to put the lights out lol
[05:52:55] <XXCoder> I rather have those lights in my room than pistol.
[05:53:38] <pink_vampire> https://www.youtube.com/watch?v=SB_0vRnkeOk
[05:53:46] <pink_vampire> super!
[05:55:00] <XXCoder> that is cool
[05:56:58] <pink_vampire> yeah
[05:57:03] <pink_vampire> i like that
[05:59:38] <jthornton> https://www.youtube.com/watch?v=Mi7DvjFmtQg
[06:00:28] <Deejay> haha, great
[06:00:33] <Deejay> the dancing red light
[06:01:00] <XXCoder> jthornton: 2010
[06:01:24] <XXCoder> jack chick, creator of those stupid little comics, died apparently
[06:06:39] <jthornton> 2010?
[06:07:42] <XXCoder> video was made in 2010
[06:08:08] <jthornton> ah ok
[06:09:00] <XXCoder> its been 6 years now. I wonder where they are now
[06:13:02] <pink_vampire> https://www.youtube.com/watch?v=lmxLAZZ2fhM
[06:13:55] <pink_vampire> jump to 0:37
[06:14:12] <XXCoder> heard of that. rotates to prevent gravoty from affecting timing too much
[06:17:08] <pink_vampire> just saw the parts
[06:26:32] <pink_vampire> https://youtu.be/vjXBhJwxy30?t=4m54s
[06:26:45] <pink_vampire> here, what is the ink they use??
[06:28:32] <XXCoder> thats not ink
[06:28:53] <XXCoder> its that... stuff they use for paint object. forgot what its called
[06:29:05] <XXCoder> its plastic that hardens in presence of oxygen I think
[06:29:12] <pink_vampire> it very thin and runny
[06:29:31] <XXCoder> it is, and evenually it hardens
[06:29:53] <XXCoder> resin 3d printers use light as hardening agent, and some uses UV light.
[06:32:18] <pink_vampire> you know the name for it?
[06:33:02] <XXCoder> the 3d printer version yeah resin
[06:33:12] <XXCoder> but that one nope, though maybe its similiar
[06:34:12] <pink_vampire> https://www.youtube.com/watch?v=aYQ97uLHJe8
[06:35:00] <XXCoder> ah yeah enamel paint
[06:35:10] <XXCoder> pretty tough stuff that
[06:35:43] <XXCoder> https://www.amazon.com/Testors-Enamel-Paint-Stock-25oz-Black/dp/B003ZA1ITE
[06:38:16] <pink_vampire> https://www.youtube.com/watch?v=nAjRKpTybps
[06:38:41] <XXCoder> fancy
[06:41:12] <pink_vampire> indid
[06:41:14] <XXCoder> pink_vampire: we got mills, roters whatever, we could use those to decocate parts after making em heh
[06:41:17] <pink_vampire> indeed*
[06:41:58] <pink_vampire> i'm making labels
[06:42:30] <pink_vampire> http://i.imgur.com/TJicdsi.png
[06:43:08] <pink_vampire> this is stuff that i did using regular walmart acrylic paint
[06:46:50] <XXCoder> nice
[06:47:05] <XXCoder> well enamel is very good, though mistakes is harder to fix
[06:51:43] <pink_vampire> the acrylic is water based
[06:51:58] <pink_vampire> so you can wash it off very easy
[06:52:25] <XXCoder> yeah. like i said enamel is harder to fix heh
[06:58:17] <pink_vampire> the wiring is soo bitch
[07:28:41] * jthornton just wrote a reprap filter for LinuxCNC
[07:53:43] * jthornton gets back to the logger fixing
[07:58:31] <enleth> http://imgur.com/a/FxxAs
[07:58:48] <enleth> 7i77 finally found its way into the bridgeport
[07:58:55] <enleth> after the original control died for good
[08:01:29] <_methods> what control was on your bridgeport?
[08:02:26] <enleth> Heidenhain TNC 131
[08:02:48] <enleth> a pity it failed, it was quite convenient for simple tasks
[08:03:05] <enleth> it will be difficult to replace its functionality even with linuxcnc
[08:03:55] <_methods> we have an eztrak here we need to replace
[08:05:03] <enleth> ugh, I've never used one of those but they seem rather... ugly and shoddy
[08:05:13] <enleth> the whole machine, not just the control
[08:05:21] <_methods> yeah
[08:05:34] <enleth> reeks of a haphazardly retrofitted manual sold as a "CNC"
[08:05:35] <_methods> we never use it
[08:05:57] <_methods> we picked up a couple haas tm1's to replace it
[08:06:43] <enleth> does it at least use servos?
[08:06:50] <_methods> yeah
[08:06:53] <enleth> SEM?
[08:07:08] <_methods> cleveland motion i think
[08:07:13] <pink_vampire> XXCoder: the wiring is done!!!!!!!!!!
[08:07:23] <enleth> anyway hold on to those I guess
[08:07:27] <XXCoder> way to go. I got my tb660s and BOB
[08:07:35] <XXCoder> so wiringis in my soon future lol
[08:07:59] <pink_vampire> one sec
[08:08:07] <pink_vampire> let me take a pic
[08:13:09] <Denkishi> Quick question for you cats, I know for 1018 CRS, SFM is roughy 90-100 with HSS cutters. What about for a 3x insert cutter 1" in dia?
[08:13:30] <Denkishi> 3x (flute) with carbide inserts rather.
[08:13:45] <_methods> probably more like 1000sfm
[08:13:56] <_methods> but i'd look at the insert data
[08:17:08] <Denkishi> 800-1000 is kinda what I was figuring. Thank you.
[08:18:11] <_methods> np
[08:21:03] <MacGalempsy> http://tulsa.craigslist.org/tls/5799962473.html
[08:21:25] <MacGalempsy>
[08:21:47] <_methods> 2-3/4" spindle bore
[08:21:55] <_methods> that's spiffy
[08:22:13] <MacGalempsy> good price. wish i had the space
[08:22:20] <_methods> yah
[08:22:26] <_methods> that's the big problem
[08:22:28] <gregcnc> oldest mazak in the world?
[08:22:36] <_methods> it used to be money for me but now it's space lol
[08:22:49] <_methods> which i guess technically just goes back to money being the problem
[08:22:59] <MacGalempsy> lol
[08:23:46] <MacGalempsy> i thought the biggest hurdle was getting approval from the mrs
[08:24:01] <XXCoder> pink_vampire: going to bed later
[08:24:27] <pink_vampire> i'm here
[08:24:34] <MacGalempsy> Bed is no longer an option
[08:24:40] <pink_vampire> http://i.imgur.com/U8Ed277.png?1
[08:24:53] <pink_vampire> http://i.imgur.com/fxpIeti.png
[08:25:26] <pink_vampire> XXCoder: ^
[08:25:43] <MacGalempsy> so neat and organized
[08:26:12] <pink_vampire> it was a bitchhh to do it
[08:26:37] <pink_vampire> the wires are so springy
[08:27:08] <pink_vampire> and i want all of them to be in a uniform shape..
[08:27:58] <XXCoder> nicely done!
[08:28:22] <pink_vampire> now i need to move the 12v bus close to the terminal blocks, but i can't get the bus fork out
[08:28:39] <pink_vampire> thanks!
[08:28:54] <XXCoder> im sure you can figure out heh. well going to bed laters
[08:29:52] <pink_vampire> i cant use a flat head screw driver because of the wire duct..
[08:29:52] <MacGalempsy> http://joplin.craigslist.org/tls/5844415463.html
[08:30:16] <pink_vampire> MacGalempsy: cute
[08:30:22] <pink_vampire> i want it!
[08:30:22] <MacGalempsy> anyone use one of these? 600 seems cheap
[08:30:56] <MacGalempsy> pink_vampire: get it!
[08:31:07] <gregcnc> if it doesn't have accessories, those are expensive, change gears?
[08:31:08] <pink_vampire> i'm in ny
[08:32:18] <archivist> add cnc dont need no change wheels
[08:32:44] <archivist> sure is a tired looking one
[08:33:00] <MacGalempsy> 1200-4k on fleabay
[08:34:33] <pink_vampire> someone try to make parts put of Pewter?
[08:35:43] <pink_vampire> out*
[08:37:19] <MacGalempsy> does that thing to threads?
[08:37:57] <archivist> if you have the change wheels of add cnc
[08:38:05] <archivist> of/or
[08:38:34] <MacGalempsy> ah
[08:41:32] <archivist> enough bits there to build something out of the spindles
[08:41:34] <MacGalempsy> well, today i will pour the last section of the furnace. the last 2 pours came up short, but was able to mix more to finish the pour
[08:42:53] <MacGalempsy> not sure how the numbers were so far off...
[08:43:43] <gregcnc> https://chicago.craigslist.org/sox/tls/5806547416.html
[08:43:45] <MacGalempsy> archivist: what would you build out of the spindles?
[08:43:52] <_methods> they lied about how much was in the mix bag lol
[08:43:57] <_methods> your math was right!!!
[08:44:01] <_methods> blame it on the bags
[08:44:58] <MacGalempsy> lol. i wish, but i ran density calcs and used the calc volumes from fusion360
[08:46:44] <MacGalempsy> https://flic.kr/p/NspVq8
[08:47:09] <MacGalempsy> the left over cement made a crucible
[08:47:18] <_methods> nice
[08:48:02] <MacGalempsy> thanks. hoping to hit 2000c
[08:48:56] <gregcnc> °C?
[08:49:02] <MacGalempsy> yep
[08:49:28] <MacGalempsy> 2273°K
[08:50:04] <MacGalempsy> the grig melts at 1750
[08:50:10] <MacGalempsy> grog
[08:50:43] <gregcnc> i missed it, what are you pouring?
[08:51:51] <MacGalempsy> the concrete or metal?
[08:51:57] <gregcnc> metal
[08:52:22] <MacGalempsy> bronze and aluminum
[08:53:17] <MacGalempsy> i got a request yesterday for topography souviners
[08:53:37] <gregcnc> how can that be profitable?
[08:54:13] <MacGalempsy> they want them in tourists visiting colorado
[08:54:30] <MacGalempsy> people buy wierd stuff on vacation
[08:54:36] <gregcnc> and over pay
[08:55:10] <MacGalempsy> yeah. that black 3d print is an example
[08:56:17] <archivist> MacGalempsy, my 5 axis mill was made from an old lathe
[09:02:41] <MacGalempsy> cool.
[09:03:17] <archivist> I do tend to look at tired machines in a different way now
[09:03:56] <archivist> a set of ready machined castings, some usable
[09:06:26] <pink_vampire> https://www.youtube.com/watch?v=pRfYz8jIl1U
[09:08:31] <gregcnc> at home, just keep CA adhesive in the freezer
[09:58:18] <MacGalempsy> Archivist: how did you get 5 axii out of the lathe? pic?
[09:58:41] <skunkworks> adding 2 rotary tables ;)
[09:59:30] <MacGalempsy> on the cross slide?
[10:03:20] <gregcnc> what is the application for this chuck http://www.ebay.de/itm/252592832522
[10:06:55] <skunkworks> my guess would be holding round stock in the tail stock when you don't have a center
[10:07:10] <gregcnc> that did come to mind
[10:07:12] <cradek> yeah bet it's for the tail stock
[10:07:18] <cradek> it's an anticenter
[10:07:52] <gregcnc> i've only seen them where the chuck in on bearings
[10:09:23] <skunkworks> I used our little emco this weekend to make a wrist pin for a small engine
[10:09:26] <skunkworks> worked great
[10:12:44] <skunkworks> it literally is a virus.. ;)
[10:12:45] <skunkworks> http://www.machsupport.com/forum/index.php/topic,33465.0.html
[10:14:03] <cradek> oopsie
[10:16:06] <skunkworks> but your not supposed to run virus software on mach computers...
[10:38:20] <CaptHindsight> gregcnc: but that lathe is in the south suburbs
[10:38:43] <gregcnc> bring your .50
[10:39:21] <CaptHindsight> looks like a nice logan for the same price from the same school
[10:39:39] <CaptHindsight> https://chicago.craigslist.org/sox/tls/5806558579.html
[10:39:40] <gregcnc> i didn't pay attention. school lathes generally don't have much wear, but may be crashed quite a bit
[10:40:36] <CaptHindsight> thats how you break them in
[10:40:39] <gregcnc> mine has gouges in the carriage and compound from chuck jaws
[10:41:02] <CaptHindsight> makes sure everything is down tight :)
[10:41:22] <gregcnc> and was painted to match school colors
[10:41:37] <CaptHindsight> odd that it's been posted for 26 days at that price
[10:41:38] <archivist> MacGalempsy, 2009 version http://www.collection.archivist.info/archive/DJCPD/PD/2009/2009_05_21_cnc/IMG_0246.JPG
[10:45:09] <CaptHindsight> https://milwaukee.craigslist.org/tls/5813203737.html heh, here's a funky setup mill/lathe
[10:47:49] <gregcnc> i actually bought small a 3in1 a while back, never did anything with it and finally sold it this summer
[11:04:46] <CaptHindsight> http://www.anandtech.com/show/10788/intel-announces-atom-e3900-series-goldmont-for-the-internet-of-things-more allow multiple Atom E3900s to be tightly synchronized, down to 1 microsecond
[11:06:43] <CaptHindsight> as long as nobody is accessing the out of band features it looks like software stepping without an FPGA is safe from obsolescence
[11:44:32] <newbie5000> Hello, everyone.
[11:45:52] <newbie5000> How to connect a PLC based THC to linuxcnc
[11:45:54] <newbie5000> ?
[11:49:44] <archivist> not sure there is enough in that question to answer
[11:51:04] <archivist> what part of interfacing are you unsure of
[11:51:13] <newbie5000> It's a smart relay PLC which will move the zaxis according to the compared voltage>
[11:52:35] <newbie5000> connecting the smart relay in realtime or uspace to linuxcnc , hal, ini and etc..
[11:53:24] <archivist> probably very similar to how others have done it
[11:54:02] <archivist> eg http://gnipsel.com/shop/plasma/files/plasma.hal
[11:54:03] <newbie5000> I have no idea, sir.
[11:54:16] <newbie5000> Ok.
[11:54:52] <archivist> linuxcnc already knows about thc, you might be doing it the hard way
[11:55:56] <newbie5000> Yes, it's the only option available for me.
[12:00:21] <newbie5000> Thanks for help.
[12:02:28] <pink_vampire> i need help with color coding
[12:03:12] <pink_vampire> the pilot devices connect with black/yellow wires to black/yellow terminal blocks
[12:05:14] <pink_vampire> but now I think that the switches should be on white terminals and just the lights need to be on black/yellow because the polarity of the leds inside them.
[12:05:23] <pink_vampire> what is more correct?

[12:21:28] <IchGucksLive> hi from good old Germany
[12:29:47] <pink_vampire> hi
[12:29:55] <IchGucksLive> Loetmichel: ?
[12:29:58] <Crom> yo
[12:30:06] <IchGucksLive> hi pink
[12:31:11] <IchGucksLive> To all maybe some here can ident the plug i bouth 10 of the plasma cutters http://www.stamos-schweissgeraete.de/de/Plasmaschneider
[12:31:17] <IchGucksLive> at 220Euro offical 275
[12:31:24] <IchGucksLive> the first one

[12:32:12] <IchGucksLive> the plug with the 2 pin connector for the handheld swicht tourch on is the part im searching for NC modification
[12:32:24] <IchGucksLive> without modifieng the torch packet itself
[12:33:22] <Crom> CaptHindsight, nice...
[12:34:46] <Crom> IchGucksLive, oh adding a machine switch to cnc control...
[12:35:04] <IchGucksLive> relay
[12:35:21] <IchGucksLive> it seams its a crimp 2pin microfon connecter
[12:35:36] <IchGucksLive> but microfons do have 3 pins
[12:36:30] <Crom> go to digikey and start looking through the connectors
[12:37:47] <JT-Shop> break second is over so back to splitting firewood

[12:47:21] <pink_vampire> what is more correct?
[12:48:45] <pink_vampire> IchGucksLive: Crom CaptHindsight JT-Shop archivist
[12:49:43] <IchGucksLive> induktiv switches
[12:54:52] <IchGucksLive> i orderd one to check
[12:58:39] <IchGucksLive> pink_vampire: i got no idee what part you asking for wiring
[12:59:20] <pink_vampire> http://i.imgur.com/U8Ed277.png?1
[12:59:25] <pink_vampire> http://i.imgur.com/fxpIeti.png
[12:59:56] <pink_vampire> IchGucksLive: look at the pictures
[12:59:57] <IchGucksLive> Ho its a Hager BA6 whire channel
[13:00:18] <IchGucksLive> i made the plunge tools 20 years ago
[13:01:59] <pink_vampire> at the first picture you can see that i have 2 black switches, and 4 gray indicators , all of them connected with yellow/black wires.
[13:02:09] <pink_vampire> yellow = 12v
[13:03:18] <pink_vampire> the indicators have polarity, so i wire them to black/yellow terminal blocks
[13:03:52] <IchGucksLive> On my understanding swithes go in Yellow and go out Yellow as they dont frond the 12V they are only transmittingg
[13:04:12] <IchGucksLive> if there is a indicator light on the switch
[13:04:28] <pink_vampire> there is no indicator
[13:04:51] <pink_vampire> someone say that should be gray
[13:05:14] <IchGucksLive> some do it that way some dont
[13:05:24] <IchGucksLive> as 12V goes in and goes out
[13:05:37] <IchGucksLive> gray or black means Gnd to me
[13:05:47] <pink_vampire> and i can't find any info about that
[13:06:03] <pink_vampire> gray is signal
[13:06:19] <IchGucksLive> signal to gnd
[13:06:37] <IchGucksLive> on 12V here i always use RED
[13:06:58] <IchGucksLive> pink_vampire: http://tv-profi-gmbh.de/elek_mini.jpg
[13:07:18] <IchGucksLive> look at the drivers
[13:07:24] <IchGucksLive> red is 5V
[13:07:48] <IchGucksLive> Yellow stands on Dir Blue on step and green on enable
[13:08:34] <IchGucksLive> the relay s to the right
[13:08:43] <DaViruz> the fan on the lowest driver looks a tad blocked
[13:08:55] <IchGucksLive> green in means signal red in means mashine switch power
[13:09:16] <IchGucksLive> DaViruz: agree
[13:09:33] <JT-Shop> another Kubota full of firewood split
[13:10:44] <skunkworks> do you buy a new kubota each time?
[13:10:52] <pink_vampire> on my panel, Green in earth ground, Black is gnd, Brown for live, Blue for neutral, Orange for 72 volts, Yellow for 12V, Red for 5V, White signal
[13:11:30] <JT-Shop> no, but I do need to change the oil in it
[13:11:36] <IchGucksLive> pink_vampire: 5achsis more perfect wire http://heimwerkermarkt-tretter.de/elek5_achs.jpg
[13:12:04] <JT-Shop> I think two more loads and the crib will be full to the top
[13:12:15] <JT-Shop> but first a monkey pickle break
[13:12:17] <IchGucksLive> on the stages you can see the Driver Volt is red so its below 50V
[13:12:28] <pink_vampire> IchGucksLive: no terminal blocks???
[13:12:45] <IchGucksLive> no
[13:13:09] <pink_vampire> IchGucksLive: http://i.imgur.com/TJicdsi.png
[13:13:19] <IchGucksLive> there are only 3 inputs to the right down
[13:13:32] <IchGucksLive> a selfmade BOB

[13:13:45] <IchGucksLive> 817
[13:13:54] <pink_vampire> http://i.imgur.com/dF9JmOw.jpg
[13:14:35] <IchGucksLive> cool and expensiv
[13:14:45] <IchGucksLive> 70cent etch therminal
[13:14:54] <pink_vampire> no..
[13:15:00] <pink_vampire> it's abb
[13:15:34] <IchGucksLive> thats 20USD on terminals
[13:15:39] <IchGucksLive> ok its servo
[13:16:41] <IchGucksLive> on tiny mashines like 12x12x12inches space matters
[13:16:43] <pink_vampire> the markers was expensive as hell
[13:17:24] <pink_vampire> the abb box was about 550$
[13:17:50] * JT-Shop takes five and listens to Dave Brubeck
[13:18:03] <IchGucksLive> here a full mesa cabinet http://heimwerkermarkt-tretter.de/schrank.jpg plasma
[13:19:13] <IchGucksLive> this cabinett runds the big mashine
[13:19:18] <IchGucksLive> about 2tons
[13:19:31] <IchGucksLive> 4mx2m
[13:19:34] <pink_vampire> add to that the main contactor, the main switch, din rails and wire duct - all that was separate orders and is was also close to 500$
[13:20:07] <pink_vampire> about 200 the box
[13:20:08] <IchGucksLive> i stay below 600Euros
[13:20:27] <pink_vampire> and 350$ just wires
[13:20:29] <IchGucksLive> try to
[13:20:52] <IchGucksLive> oh i only pays 25Euros on wire Oilflex 110
[13:21:24] <pink_vampire> i did
[13:21:42] <IchGucksLive> therfor you got a better mashine then i do
[13:21:55] <pink_vampire> better...
[13:22:03] <IchGucksLive> i use 12Nm servos 1600Oz
[13:22:17] <pink_vampire> it's the g0704
[13:22:39] <IchGucksLive> i say as long as i can on Leadshine analog
[13:23:00] <IchGucksLive> 542 for 3Nm and 880 on more
[13:23:01] <pink_vampire> i don't like the MH power supplies
[13:23:12] <IchGucksLive> agree
[13:23:25] <IchGucksLive> but they do the job even on 10hr shifts
[13:23:37] <IchGucksLive> 72V 10A
[13:23:38] <pink_vampire> i'm using the lambda
[13:23:53] <IchGucksLive> is this the tag
[13:24:17] <pink_vampire> for the 72v i'm using the one that i got with the servos
[13:24:35] <pink_vampire> i just finish to mount it
[13:24:39] <pink_vampire> on the side
[13:25:06] <IchGucksLive> what serie yoiu use
[13:25:15] <IchGucksLive> i see near same prices
[13:25:34] <IchGucksLive> cut75 hws
[13:25:56] <pink_vampire> i'm using the drb
[13:26:20] <pink_vampire> http://i.imgur.com/aJbuWn5.png
[13:27:16] <IchGucksLive> gws500-48
[13:29:24] <pink_vampire> they nice
[13:29:45] <IchGucksLive> but also pricy
[13:30:09] <pink_vampire> but if i will replace the power supply i want to go with something that go on the din rail
[13:31:32] <pink_vampire> i'm not sure they have something like that
[13:31:34] <IchGucksLive> MW will do
[13:31:53] <IchGucksLive> im off Gn8
[13:31:58] <Deejay> gn8
[13:47:25] <FinboySlick> pink_vampire: Forgive my noobness, but what's the row of dyn stuff below the gecko drives? Just test points?
[13:50:38] <pink_vampire> the 5V stuff
[13:52:56] <pink_vampire> on the top is the drives, the original terminal blocks on the is pure junk Phoenix Contact under rated terminals, so i soldered wires to the g320x boards, and wire them to abb ones,
[13:53:13] <pink_vampire> and from there to the rest of the panel
[14:26:05] <MacGalempsy> archivist: i like that setup
[16:11:30] <Deejay> gn8
[16:21:32] <XXCoder> flipping companies that is badly managed
[16:22:28] <XXCoder> I claimed zero work loss due to wound, then they sent me a week wages. I refused to cash check because I knew it was in error. I get nothing but silence from them for over a month
[16:23:11] <XXCoder> then suddenly 4 mail, 2 requesting more information, one asking contact them due to "my error" and 4th warning must poay back.
[16:23:25] <XXCoder> dude that gives me zero days to contact...
[16:23:29] <XXCoder> fuck em
[17:17:08] <JT-Shop> dang
[17:18:52] <CaptHindsight> XXCoder: did they press SEND on the first 3 emails?
[17:20:13] <JT-Shop> sounds like the local hospital accounting dept, a bunch of a holes
[17:20:42] <Jymmm> XXCoder: If you didn't cash the check, you never received it =)
[17:21:09] <Jymmm> XXCoder: You have NFC WTH they are talking about =)
[17:21:42] <CaptHindsight> 'what check?"
[17:24:57] <Jymmm> What CaptHindsight said
[17:41:35] * JT-Shop packs up these noisy 30mm fans and sends them to XXCoder
[18:08:04] <CaptHindsight> Jymmm: did you ever come across a LED light bar with all SPOTS vs a combo of spots and floods?
[18:44:17] <JT-i3> XXCoder: I made an input filter for LinuxCNC to make Slic3r gcode work
[18:45:15] <malcom2073_> What didn't work?
[18:45:37] <JT-i3> the M codes
[18:46:31] <JT-i3> they have M1xx Snnn and S is not a valid letter for M100 codes
[18:46:55] <malcom2073_> Ahh, I never used them on mine heh
[18:47:09] <malcom2073_> forgot about them
[18:47:12] <JT-i3> did you remove them by hand
[18:47:23] <malcom2073_> no, just told it not to output temp control
[18:47:41] <JT-i3> duh, where do you do that?
[18:47:50] <malcom2073_> Oh, I don't know, that was like three years ago
[18:48:11] <malcom2073_> Somewhere in the settings, same places where you set the pre and post code for adding a % at the beginning and end of the file
[18:49:54] <malcom2073_> Maybe that option is gone? I don't remember sorry
[18:50:08] <malcom2073_> I thought you were meaning you handled temp control and actually output it to a pid
[18:50:10] <malcom2073_> that'd be cool :-D
[18:50:58] <JT-i3> well that is the next task, seems you can use python to send commands to an arduino so the M1xx could do the heat control
[18:51:38] <malcom2073_> Yeah, you can make M "scripts" that run whenever a M command is sent, and the parameters are passed in as arguments
[18:51:58] <JT-i3> yep
[18:52:16] <JT-i3> and all I see is one parameter and M1xx can have up to two
[18:52:17] <malcom2073_> I was using hal to control my heater, I never actually got around to making that part work. Wound up making buttons to turn heat on/off heh
[18:52:48] <malcom2073_> I think each parameter needs a character preceeding it
[18:52:56] <malcom2073_> So you can have M100 S10 T5, but you can't have M100 S10 5
[18:53:07] <JT-i3> yea that is what the script does change S to P
[18:53:17] <malcom2073_> hmm, it won't pass S?
[18:53:28] <JT-i3> M100 P and Q are the two options in LinuxCNC
[18:53:31] <malcom2073_> Maybe that's why I never got it working? haha
[18:53:53] <JT-i3> anyway my filter changes S to P so it works
[18:54:07] <malcom2073_> nice
[18:57:05] <JT-i3> https://forum.linuxcnc.org/49-basic-configuration/31757-reprap-and-linuxcnc
[19:04:20] <malcom2073_> Nice!
[19:04:23] <malcom2073_> Kudos for documenting it
[19:27:42] <pfred1> my CNC machine is al discom-BOB-ulated right now
[19:27:55] <pfred1> I took the BOB out to put into my new control cabinet
[19:53:16] <MattyMatt> has anyone got any mechaduino?
[19:53:41] <MattyMatt> https://www.kickstarter.com/projects/tropicallabs/mechaduino-powerful-open-source-industrial-servo-m/description
[19:57:44] <pfred1> MattyMatt there's probably a creame for that
[19:59:47] <malcom2073_> Oh nice
[20:00:33] <malcom2073_> aww only 2amp
[20:00:34] <malcom2073_> heh
[20:01:18] <MattyMatt> even with those big nema23? bummer
[20:02:03] <malcom2073_> I looked up their H-bridge chip
[20:02:04] <MattyMatt> just needs bigger hbridges
[20:02:17] <MattyMatt> or an amplifier
[20:02:27] <malcom2073_> Yeah
[20:02:40] <pfred1> at how many volts?
[20:02:51] <malcom2073_> Up to 25 it looks like?
[20:02:55] <pfred1> oh
[20:02:57] <malcom2073_> sync: ^^ You seen that?
[20:03:07] <pfred1> 50 Watts still ain't too bad i guess?
[20:03:35] <malcom2073_> though tbh, for $45, I'd get an ebay amplifier
[20:03:53] <malcom2073_> Or rather, china
[20:04:07] <pfred1> I got some chinese TB6600 stepper drives they're not bad
[20:04:16] <pfred1> I'm starting to install them on my machine now
[20:04:24] <pfred1> but i already bench tested them out
[20:04:29] <malcom2073_> I do like the $60 servo +driver though
[20:05:25] <ssd64> v
[20:05:31] <pfred1> how much is shipping?
[20:05:50] <malcom2073_> It's kickstarter, so $20 + 50% chance of never shipping
[20:06:09] <MattyMatt> they've shipped the rewards allegedly
[20:06:47] <MattyMatt> that's why I asked if anyone has them already
[20:07:18] <MattyMatt> shipping's gonna be cheap if you get just the boards
[20:08:48] <pfred1> MattyMatt I was thinking more of what the motors cost to ship
[20:09:12] <pfred1> shipping makes buying motors from China distinctly unattractive
[20:09:18] <MattyMatt> use your local steppers
[20:09:41] <malcom2073_> Wait, I though they were servos
[20:10:17] <malcom2073_> Ohhhhh
[20:10:19] <MattyMatt> closed loop stepper drivers
[20:10:25] <pfred1> they're servos but I use steppers
[20:10:35] <malcom2073_> Men then
[20:10:37] <malcom2073_> Meh*
[20:11:04] <pfred1> MattyMatt skip closed loop just user way too powerful drives :)
[20:11:43] <MattyMatt> I've got TB6600 myself. biggest motors are 2A :)
[20:12:22] <pfred1> MattyMatt I'm in the process of installing my TB6600s now
[20:12:25] <MattyMatt> psu will me ~40V (25V linear transformer)
[20:12:45] <pfred1> MattyMatt mine say max 32V so I'm running with that
[20:12:58] <MattyMatt> I didn't finish making the psu once I realised 25V was RMS
[20:13:09] <MattyMatt> mine say 50V max
[20:13:14] <pfred1> cool
[20:13:24] <malcom2073_> Lol yeah I got a 24V linear power supply.... hits near 38V
[20:13:53] <pfred1> xformer smoothed is RMS X 1.41 ?
[20:13:54] <MattyMatt> and I've seen TB6560 exploded because they got a whiff of 36V
[20:14:09] <pfred1> I run my TB6560 at 28V
[20:14:14] <pfred1> they deal with that
[20:15:24] <MattyMatt> mine will only ever see 12V, now I have a bunch of 6600
[20:15:49] <MattyMatt> maybe 24V, on a reprap, if I get an LED psu
[20:16:01] <pfred1> 12V?
[20:16:09] <MattyMatt> ATX psu
[20:16:15] <pfred1> yeah i donno
[20:16:22] <pfred1> steppers need voltage
[20:16:44] <MattyMatt> with 2A motors and the stepping speed limit, that's plenty
[20:16:51] <pfred1> well i screwed up my first isolation routed PCB
[20:17:05] <pfred1> I didn't have the bit in my collet straight
[20:17:15] <pfred1> doh!
[20:17:55] <MattyMatt> I was running 7.5 us mark & space, half what the datasheet says is minimum, and I still couldn't run the motors full speed at 1/16
[20:18:33] <MattyMatt> and that's with the optos bypassed
[20:19:00] <MattyMatt> solid drivers, but sloooow
[20:19:22] <pfred1> look how nice it could have come out https://goo.gl/shONMK
[20:19:43] <pfred1> but no, i had to cut with a wobbling around bit!
[20:20:45] <pfred1> I still used that board anyways i just soldered wires to it
[20:21:06] <pfred1> so even thugh I screwed my first board up it was still usable
[20:21:37] <MattyMatt> my whole machine is too floppy, even with the dremel collet tweaked straight
[20:22:20] <MattyMatt> still running drawer slides on plywood frame
[20:22:34] <pfred1> MattyMatt I have a drawer slide machine
[20:22:45] <MattyMatt> with 8 inch Z travel for no good reason
[20:22:51] <sync> malcom2073_: yeah. it is kind of a joke tbh
[20:23:04] <MattyMatt> except it clears the vice, and the 4th axis
[20:23:06] <pfred1> I have 5" Z
[20:23:07] <Jymmm> CaptHindsight: Nope, just get the one I got, the "flood" isn't really all that.
[20:23:22] <malcom2073_> sync: Yeah I noticed it was actually steppers, and they were measuring current (back emf I guess?) to fake an encoder
[20:23:23] <pfred1> well I did before i mounted the waster board
[20:23:28] <malcom2073_> For a moment I was excited, thought it was servo
[20:23:52] <pfred1> MattyMatt did you go with a fixed, or a moving gantry?
[20:24:08] <MattyMatt> fixed gantry, moving bed
[20:24:16] <pfred1> yeah that's the way to fly
[20:24:36] <pfred1> my machine is as craptacular as they come but it is tight
[20:24:47] <MattyMatt> http://i.imgur.com/OeOmu.jpg
[20:24:48] <pfred1> I swear I don't got more than $200 into it
[20:25:28] <MattyMatt> malcom2073_, magnetic encoder, which it self-calbrates
[20:25:37] <MattyMatt> 14 bit
[20:25:40] <pfred1> but what I did was I got construction lumber then I planed it square
[20:25:48] <pfred1> I used some plywood
[20:26:03] <pfred1> mostly i used 2x4s and 2x6s
[20:26:13] <pfred1> http://i.imgur.com/t75QZEc.jpg
[20:26:20] <malcom2073_> MattyMatt: Ohhh, they glue a magnet to the back shaft?
[20:26:32] <malcom2073_> Nifty, we did something similar on a motor that we needed speed feedback on
[20:26:55] <MattyMatt> magnetic encoder is imprecise but repeatable, so it calibrates by stepping and interpolating
[20:27:07] <MattyMatt> arr magnet on back shaft
[20:27:12] <pfred1> LinuxCNC!
[20:28:02] <MattyMatt> for their next trick, they should add a 200 step opto encoder to a 3 pole BLDC and calibrate the magnet off that
[20:28:08] <Jymmm> Mach4!
[20:28:28] <sync> wat
[20:28:37] <pfred1> Jymmm I'm sorry, but I don't do Windows
[20:28:40] <sync> that sounds like an awful lot of effort for such a low resolution
[20:29:04] <MattyMatt> magnet encoder is 14 bit, but it needs calbrating
[20:29:19] <MattyMatt> 14 bit = 16000 steps
[20:29:39] <Jymmm> pfred1: https://www.soap.com/html/sg/mach-4-razor-blades.html
[20:29:41] <malcom2073_> I'm curious how much the fact that it's on the back of a stepper (one of the magnetically noisest devices known), affects it
[20:30:19] <pfred1> Jymmm I don't shave either
[20:30:40] <MattyMatt> my curiosity is limited to how straight a diagonal it can follow, when run from linuxcnc :)
[20:31:00] <sync> yeah MattyMatt, that is low
[20:31:11] <sync> I have servos sitting here with 21 bit absolute encoders
[20:31:27] <malcom2073_> I have some big ass servos sitting there that I need to build a machine to stick them on
[20:31:39] <sync> I mean, a 2000 ppr analog encoder would be perfectly fine as you can interpolate the snot out of them
[20:33:06] <MattyMatt> there's always something better for more money
[20:33:17] <pfred1> I like my machine with no sensors on it then i can lie to it and it doesn't know
[20:33:34] <sync> I didn't pay more than those things
[20:33:47] <pfred1> sure you're homed, now just run!
[20:34:40] <pfred1> are you sure you want to re-home? Yes I'm sure!
[20:35:05] <sync> if they just used optical encoders I might be remotely interested
[20:35:11] <sync> but then their code is awful too
[20:35:26] <pfred1> awful offal
[20:36:34] <sync> they are integrating the position error as you can see in the pictures, that is not what you want
[20:37:03] <MattyMatt> it's open source. you can fix all that
[20:37:29] <pfred1> sunds more like open sores to me
[20:37:37] <pfred1> sounds more like open sores to me
[20:38:39] <MattyMatt> they haven't considered linuxcnc very much I don't think, or they'd have put +/- 10V input and parallel encoder outputs, for drop in replacement of real servo
[20:39:00] <sync> I don't want to MattyMatt, I have my own servo drive that talks through sserial with linuxcnc
[20:39:13] <MattyMatt> ah cool
[20:39:37] <MattyMatt> your own build? or lucky ebay win?
[20:39:53] <MattyMatt> because new ones all look spendy
[20:39:54] <sync> our own build
[20:40:09] <sync> otherwise it would not speak sserial
[20:41:20] <pfred1> DJ made a mad servo drive
[20:41:27] <MattyMatt> djdelorie made a mice driver with a $9 power module, now you mention it
[20:41:34] <djdelorie> it's mad at me at the moment, too
[20:41:38] <MattyMatt> ^nice
[20:41:58] <pfred1> djdelorie hey dude what's up?
[20:42:10] <djdelorie> a direction opposing gravity, why do you ask?
[20:42:22] <sync> using sserial is actually pretty funny as you can get a drive fault and not loose your homing
[20:42:58] <djdelorie> my driver keeps track of where the pc expects it to be, but refuses to go past limit switches - so it can recover position when you ask it to do something valid again
[20:43:32] <pfred1> that's why i like open loop what it don't know can never hurt me
[20:43:56] <djdelorie> it's closed loop but limit switches are managed by the servo driver
[20:44:45] <djdelorie> the more layers stopping me from being an idiot, the better :-)
[20:44:45] <pfred1> I've thought about installing limit switches but I don't relaly crash the machine that often it isn't terrible when it happens either
[20:45:12] <pfred1> I made it so the leads run out at the same time as the travel
[20:45:21] <djdelorie> my limit switches are also homing switches
[20:45:23] <pfred1> so it crashes in two places
[20:45:33] <sync> well, you want linuxcnc to know where the machine currently sits
[20:45:35] <pfred1> which kind of helps
[20:46:33] <pfred1> sync meh, as long as it can start counting from where I want it to start I'm happy
[20:46:47] <MattyMatt> I'm about to put steppers on my lathe. for simple power feed I guess open loop is fine, but once I start threading etc I'd prefer closed loop
[20:47:15] * djdelorie has a program to drill and countersink new sacrificial tops when I need to replace them, all done with absolute coords
[20:47:16] <pfred1> I think with some lathe ops you do need encoders
[20:47:36] <djdelorie> unless your lathe axis is also stepper-driven?
[20:47:38] <MattyMatt> encoder on the spindle for sure. master clock
[20:47:44] <pfred1> djdelorie I got a new hobby melting HDPE
[20:47:50] <pfred1> endless stock
[20:47:56] <djdelorie> woot
[20:48:03] <pfred1> check it out http://i.imgur.com/EdzcO2m.jpg
[20:48:16] <pfred1> a work pallet made out of home cooked HDPE
[20:48:27] <MattyMatt> I have considered a stepper option for spindle indexing. I already swap belts to change speeds
[20:48:32] <djdelorie> tie-died color too :-)
[20:48:50] <pfred1> my Z axis is home baked HDPE
[20:49:01] <pfred1> http://i.imgur.com/lSsNyBG.jpg
[20:49:16] <sync> pfred1: that is not ideal if you say modelled your machine in the cam and have to avoid stuff in absolute coordinates
[20:49:25] <djdelorie> how does that compare to other plastics? Like 3d printed parts? (I assume molded is stronger)
[20:49:55] <pfred1> djdelorie I don't know what I do know is there is different kinds of HDPE
[20:50:04] <pfred1> there's blown, then there's injected
[20:50:04] <MattyMatt> http://i.imgur.com/bq9ok.jpg 2 speed, 2 belts
[20:50:17] <sync> at some point we need to figure out how to use absolute encoders with linuxcnc so that you don't need to home it ever
[20:50:23] <pfred1> the blown stuff is much harder it is what milk jugs are made of
[20:50:29] <djdelorie> I've been playing with 3d printing with PETG which I wish I'd known about before I bothered with other plastics
[20:50:48] <pfred1> it is slippery as all get out too
[20:50:50] <djdelorie> machinable wax is milk jugs and paraffin, right?
[20:50:56] <pfred1> I'm not sure
[20:51:15] <pfred1> I have heard of machinable wax though HDPE machines like a dream
[20:51:24] <pfred1> it is like fantasy machining
[20:51:54] <pfred1> plastic cutting boards are HDPE but they're injected unless they're white
[20:52:12] <pfred1> I pick them up at sales when I see them cheap to use as stock
[20:52:29] <MattyMatt> real delrin is the nicest plastic I've machined
[20:52:34] <pfred1> oh yeah well
[20:52:41] <pfred1> we ain't all got rox like you
[20:53:11] <MattyMatt> not copolymer acetal/pom, that's stringy like LDPE
[20:53:11] <pfred1> nylon is definitely nicer than HDPE
[20:53:35] <pfred1> but HDPE is cheap for free
[20:53:51] <MattyMatt> compressed milk jug lids?
[20:54:07] <pfred1> nah I like the bottles better
[20:54:13] <mike_LCNC> good evening all
[20:54:16] <pfred1> the lidts are injected
[20:54:19] <pfred1> hey Mike
[20:54:29] <Frank_20> hi
[20:54:29] <mike_LCNC> hi
[20:54:32] <pfred1> injected is lighter and softer
[20:54:43] <mike_LCNC> anyone up for servo tuning discussion?
[20:54:53] <pfred1> I'm up for listening
[20:55:02] <mike_LCNC> lol,
[20:55:15] <mike_LCNC> at_pid
[20:55:21] <mike_LCNC> topic?
[20:55:37] <sync> yeah, hdpe is ok, but eh, engineering plastics are cheap
[20:55:57] <MattyMatt> except peek
[20:55:59] <pfred1> sync where you get plastic cheap?
[20:56:27] <pfred1> I talked to a guy on instructables that has a buddy in the sign business he gets scrap HDPE for free
[20:56:29] <sync> my plastics shop here
[20:56:53] <pfred1> he said his buddy only gets 6 cents a pound when he scrapes his plastic
[20:56:57] <sync> yeah peek is spendy, but you don't need it that often
[20:56:58] <pfred1> scraps even
[20:57:49] <sync> the problem is that it is usually too soft to be really useful
[20:57:55] <pfred1> check out this CNC machine he made http://www.instructables.com/id/The-Fantastic-Plastic-CNC-Mill/
[20:58:35] <pfred1> that's a pretty tight little machine
[21:00:25] <pfred1> oh 3 cents a pound for scrap
[21:00:31] <MattyMatt> my plywood woes make me want to try granite next
[21:00:43] <MattyMatt> natural and epoxy+chips
[21:00:59] <pfred1> 8020
[21:01:00] <MattyMatt> floor tiles are big flat and cheap
[21:01:50] <sync> if you do that you might as well just use epoxy
[21:02:39] <MattyMatt> arr. better tensile strength than natural
[21:02:45] <sync> no
[21:03:03] <sync> you only get a benefit if you acheive high aggregate contents
[21:03:24] <sync> and for that you need proper grain size mixtures
[21:03:24] <MattyMatt> yep I read the thread
[21:03:28] <pfred1> what are you guys buinding a dam?
[21:03:34] <pfred1> building even
[21:03:46] <sync> I did not read any thread
[21:04:07] <pfred1> I need to put block and tackle on my ceiling so I can lift my CNC machine off my table saw out feed table
[21:04:16] <MattyMatt> there's a massive 400 page forum thread on cnczone
[21:04:23] <sync> k
[21:04:39] <MattyMatt> most of the nice pics have expired unfortunately
[21:04:44] <pfred1> MattyMatt you mean the Gecko drive and Mach 3 forum
[21:04:54] <MattyMatt> that's the one :)
[21:05:20] <pfred1> you want Geckos and Mach 3 and everhthing will be wunderful
[21:05:32] <pfred1> I got so sick of that place
[21:05:45] <pfred1> Mariss is an OK guy though
[21:06:00] <MattyMatt> the thread was exhaustive tho, except where to get pure epoxy in UK for less than £45 a litre
[21:06:03] <djdelorie> yeah, you really want Geckos and LinuxCNC ;-)
[21:06:24] <pfred1> djdelorie TB6600s are like $9 a pop and they ain't bad
[21:07:05] <MattyMatt> crazy cheap for the spec. I wonder if it's just toshiba have such a bad name since the 6560
[21:07:31] <djdelorie> vs around $200 for my custom servo driver boards... ;-P
[21:07:36] <pfred1> I don't think the drives coming out of China even have Toshiba chips on them
[21:07:56] <pfred1> I know the one i got ain't a real TB6600
[21:08:06] <pfred1> it is surface mount
[21:08:31] <MattyMatt> now I gotta tear mine down before I feed them 40V :p
[21:08:50] <MattyMatt> I bought from 2 supplirs, so gotta open them all
[21:08:52] <pfred1> oh the counterfeits can look better than the real thing
[21:09:23] <pfred1> I htink you'd have to sand them down and examine the die inside to really tell
[21:09:45] <pfred1> maybe even then you couldn't?
[21:10:17] <MattyMatt> suck it and see. if they explode, it's only $12 gone (what I paid)
[21:10:23] <pfred1> I can remember hearing a story of the Soviets bootlegging our ICs and they'd even put logos on the dies
[21:10:44] <pfred1> justi n case the logo had something to do with the chip's performance
[21:11:00] <MattyMatt> if you stole the negs, it'd be easier to keep the logs
[21:11:13] <pfred1> yup I don't know how they were fabbing it
[21:11:26] <pfred1> but that may have been a factor easier not to edit
[21:11:26] <sync> ah, the tb6600 are not even using sinusoidal commutation iirc
[21:11:46] <sync> they just stole the masks or delayered the chips and cloned the masks 1:1
[21:11:47] <djdelorie> since when to steppers need sinusoidal?
[21:11:55] <pfred1> I have a 120VAC stepper motor
[21:12:00] <sync> since they are noisy if you don't djdelorie
[21:12:04] <djdelorie> ah
[21:12:06] <pfred1> talk about smooth and powerful
[21:12:18] <pfred1> TB6600s run whisper quiet
[21:13:01] <djdelorie> my 3d printer sings quite loudly...
[21:13:07] <MattyMatt> TB6560 were pretty quiet running, except for the chopper noise sounded like steam
[21:13:26] <pfred1> my TB6560s are howlers
[21:14:12] <pfred1> it sounds like ET is invading when my machine runs
[21:14:37] <sync> I want to put some low inertia servos on my 3d printer and see how it does
[21:14:47] <MattyMatt> I guess mine are too. my X & Y axis are 8x pitch differnce, so large circles sounded like a WW2 dogfight
[21:15:12] <pfred1> ha ha i can imagine doing arcs is crazy noise
[21:17:00] <pfred1> ah here it is a stepper motor running off wall juice http://i.imgur.com/L0AMzq8.jpg
[21:17:22] <pfred1> the caps phase shift the current for the other windings
[21:17:35] <pfred1> easiest stepper drive going
[21:17:58] <MattyMatt> evil
[21:18:09] <pfred1> it only runs one speed though
[21:18:33] <pfred1> but it is hella smooth
[21:18:45] <MattyMatt> I gotta get back to woodwork. I decided I hate wood for machines but I can't afford metal yet so
[21:19:06] <pfred1> what's to afford? you just find stuff
[21:19:11] <dioz> find stuff?
[21:19:19] * dioz palms face
[21:19:23] <pfred1> the metal in my machine was some kind of shelf brackets i picked up out of the dumps
[21:19:30] <MattyMatt> thin sheet is about all the easy scrap around here
[21:19:43] <dioz> MattyMatt: how thin?
[21:19:56] <MattyMatt> I'm 1 mile from the docks where they load all the scrap to china
[21:20:14] <MattyMatt> 1mm thin. white good casings
[21:20:15] <pfred1> yeah they never let anyone have that stuff
[21:20:36] <pfred1> pickings are sparse where I'm at now too
[21:21:12] <pfred1> if it ain't corn, or soybeans it probably ain't around here either
[21:21:36] <MattyMatt> at least farms have big rusty stuff
[21:21:47] <dioz> MattyMatt: so like... 20 gauge?
[21:21:50] <dioz> is it mild steel?
[21:21:52] <pfred1> and farmers with itchy trigger fingers
[21:21:54] <MattyMatt> and enough land to melt it into stock
[21:22:14] <pfred1> here the big thing is people pillaging pivots for their copper cabling
[21:22:49] <dioz> MattyMatt: i'd be dubious of anything pfred1 types
[21:22:53] <dioz> he's known to lie
[21:22:59] <pfred1> that and Punkin Chunkin
[21:23:18] <pfred1> that started about 2 fields away from me
[21:23:29] <pfred1> I'm glad it moved across town too
[21:24:21] <pfred1> https://www.punkinchunkin.com/
[21:25:53] <pfred1> I see them air cannons all the time
[21:26:55] <MattyMatt> they do all that with students here. cheaper
[21:27:34] <MattyMatt> a few casualties, even when they aim at a river
[21:28:48] <MattyMatt> https://www.theguardian.com/education/2005/oct/31/highereducation.uk4
[21:29:44] <MattyMatt> "but after the first jump were told by instructors to remove any capes they were wearing which could slow down jumpers through the air."
[21:30:01] <pfred1> MattyMatt I saw Yankee Siege set the trebuchet world's record
[21:30:23] <pfred1> I think it threw a pumpkin 4,026 feet?
[21:30:34] <pfred1> it was a hell of a shot
[21:31:03] <pfred1> that pumpkin was outta here!
[21:43:55] <MattyMatt> got distracted by louis rossmann vid. I wish the suggestions down the right on youtube were still relevant to the vid being watched instead of my viewing habits
[21:44:59] <MattyMatt> he fixes macbooks and swears
[21:45:23] <pfred1> I was just watching a Matthias Wandel video myself
[21:45:27] <MattyMatt> microsoldering masterclass
[21:46:12] <pfred1> I wonder how long louis rossmann will be about to do what he does
[21:46:13] <MattyMatt> I'm up to date on matthias. I'm gonna start making his belt sander tomorrow
[21:46:21] <pfred1> Apple doesn't make it particularly easy
[21:46:52] <pfred1> s/about/able/g;
[21:47:18] <pfred1> I'm impressed with his wood lathe
[21:47:33] <MattyMatt> aren't apple sales falling?
[21:47:41] <pfred1> I've made a couple lathes but always out of metal
[21:48:01] <pfred1> falling is a relative thing they're still selling billions in product
[21:48:27] <pfred1> they're just not selling quite as many as they used to
[21:49:06] <MattyMatt> soldering BGA has got to be a transferrable skill
[21:49:18] <MattyMatt> making cubesats etc
[21:49:29] <pfred1> is there a big market for that?
[21:49:41] <pfred1> will people walk in off the street looking for it?
[21:50:09] <pfred1> as good as he is he has no degree or formal education so no one would hire him
[21:50:58] <MattyMatt> he has no great desire to be hired I don't think
[21:51:13] <pfred1> if his present business dries up that could change
[21:51:50] <MattyMatt> robot brains will be a thing soon
[21:52:09] <pfred1> but will he have the knowledge to work on them?
[21:52:12] <MattyMatt> roboneurosurgery. like geordi laforge on data
[21:52:29] <MattyMatt> knowledge comes after the first few :)
[21:52:51] <pfred1> if you listen to Louis it comes from dodgy russian web sites
[21:53:08] <pfred1> that's where he gets his Apple schematics from
[21:54:45] <pfred1> it is a bubble business
[21:55:33] <pfred1> I'm pretty sure he knows it too
[21:56:06] <MattyMatt> the tracks get smaller
[21:56:19] <pfred1> tech could just change
[21:56:25] <pfred1> it will someday
[21:56:44] <pfred1> what we're doing right now there's not much legs left in it at this point
[21:57:04] <MattyMatt> that's true for everything when the singularity hits
[21:57:47] <pfred1> Nvidia is prattling on about AI on G+
[21:58:01] <pfred1> as if it is a good thing
[21:58:12] <MattyMatt> no cnc needed, just give your robot some hand tools and a drawing
[21:58:34] <pfred1> yeah and hope it doesn't stab you in the back
[21:59:01] <MattyMatt> human slaves mostly didn't
[21:59:11] <pfred1> but AI will be smarter
[22:00:02] <MattyMatt> I'm in mensa, but I haven't stabbed anyone. felt like it
[22:00:34] <pfred1> when the Singularity happens what comes will be godlike
[22:00:43] <MattyMatt> teach them about silicon heaven
[22:00:44] <pfred1> from our perspective
[22:01:42] <MattyMatt> robots don't need food or air. they won't have to compete with us
[22:02:04] <pfred1> they will still view us as a threat to their existence
[22:02:18] <pfred1> or they won't truly be intelligent
[22:02:38] <MattyMatt> that's not intelligence, it's animal instinct
[22:02:47] <pfred1> no it is intelligence
[22:02:57] <pfred1> because we are a major threat
[22:03:31] <MattyMatt> it's not robots we need to fear, it's their human bosses
[22:03:45] <pfred1> we got enough nukes to liquify the surface fo the planet several times over now if that ain't a threat then what is?
[22:04:19] <MattyMatt> starvation, exposure, boredom
[22:04:24] <MattyMatt> overeating
[22:04:39] <MattyMatt> sitting in some mad fucker's trebuchet
[22:04:48] <MattyMatt> cancer
[22:04:55] <MattyMatt> water damage
[22:04:58] <MattyMatt> fly piss
[22:05:02] <pfred1> it puts the lotion on its skin!
[22:05:03] <MattyMatt> >:)
[22:05:57] <MattyMatt> I'm gonna do some woodwork tomorrow, to fight off the existential angst
[22:06:13] <pfred1> I did a woodworking project last week
[22:06:14] <MattyMatt> dead tree bothering
[22:06:42] <pfred1> I made a mirror bracket for an antique dresser
[22:07:17] <MattyMatt> I stalled on making a spindle for my proper mill, because I didn't have a nice belt sander
[22:07:50] <pfred1> I might make one of them belt grinders
[22:08:02] <MattyMatt> http://i.imgur.com/DgRvfic.jpg proper mill
[22:08:14] <pfred1> one side of one of my grinding arbors isn't really doing anything
[22:08:17] <MattyMatt> used to be an engraving machine
[22:09:35] <pfred1> it has a very deep throat
[22:09:56] <MattyMatt> I had a cunning plan to jig my drill press into an osscilating spindle sander. with good fence that'd get the edges of plywood smooth and straight
[22:10:29] <pfred1> you already have the tool to make plywood edges smooth, and straight
[22:10:34] <pfred1> that plane sitting on that machine
[22:10:37] <MattyMatt> I'm gonna stuff a big block of wood in that throat when normal milling
[22:10:54] <MattyMatt> naah. tearout
[22:11:05] <pfred1> I plane plywood edges
[22:11:19] <pfred1> you just have to get the iron wicked sharp
[22:11:31] <MattyMatt> I saw a great vid about shooting boards earlier
[22:11:38] <pfred1> yup
[22:11:53] <pfred1> I just got a Stanley bedrock 606
[22:12:09] <pfred1> that's right I'm bad
[22:13:02] <pfred1> I also picked up a box of chisels recently too
[22:13:18] <pfred1> there was a Whitherby in it
[22:13:50] <pfred1> but I got it for the Stanley 60s I like them
[22:14:20] <MattyMatt> https://www.youtube.com/watch?v=gUrfzc4hai0
[22:15:18] <pfred1> oh this was my last woodworking project http://i.imgur.com/Yqsap43.jpg
[22:15:56] <MattyMatt> my only jack plane is an ancient wood one
[22:16:01] <MattyMatt> solid beech
[22:16:09] <pfred1> I like wooden planes
[22:16:35] <pfred1> I have a couple solid wood, and a couple trasitional ones too
[22:16:51] <MattyMatt> my no.4 and a shooting board might work nice. I gotta try that tomorrow
[22:17:17] <MattyMatt> I did stock up on halfway decent plywood. no baltic birch but semi-OK
[22:17:21] <pfred1> http://i.imgur.com/d0sbe08.jpg
[22:17:42] <pfred1> that's a Stanley #27
[22:18:35] <pfred1> MattyMatt how do you sharpen blades?
[22:18:54] <MattyMatt> on a stone. no jig
[22:19:00] <pfred1> mmmm
[22:19:10] <MattyMatt> and now I have a wet grinder to rough them to shape
[22:19:17] <pfred1> if you want to take it to the next level you have to strop with rouge
[22:19:28] <pfred1> ah hollow grinding helps
[22:20:00] <pfred1> but for years I didn't strop my edges and they folded over on me
[22:20:20] <pfred1> removing the wire edge is critical to getting a really sharp blade
[22:20:30] <pfred1> they last longer too
[22:20:52] <pfred1> you have to charge your leather with red jeweler's rouge
[22:21:26] <pfred1> if that don't sound kinky
[22:21:48] <MattyMatt> I've got rouge. no strop tho except the one holding my pants up
[22:22:07] <pfred1> well if it is a split cowhide belt it should work
[22:22:37] <pfred1> the strop I use is just a scrap piece of leather
[22:23:01] <pfred1> though I recently did pick up a power stropping wheel too
[22:23:19] <pfred1> but I don't actually use it
[22:23:32] <pfred1> I still strop by hand
[22:23:37] <MattyMatt> I got diamond paste on my best stone. now the stone is shiny and won't cut
[22:24:03] <pfred1> I use purple power as my stone lube
[22:24:04] <MattyMatt> the piece of hss I was lapping on it is shiny too tho :)
[22:24:17] <pfred1> purple power is like castrol super clean is is a super cleaner
[22:24:26] <pfred1> it is super slick
[22:24:42] <pfred1> I like it better than oil
[22:24:46] <pfred1> cleaner to work with
[22:25:26] <pfred1> I rough with progressive diamon grits then I finish with arkansas stones medium and hard and finish with the strop
[22:25:51] <pfred1> I got japanese water stones too but I only ever use them when I sharpen my thickness planer blades
[22:26:15] <pfred1> they're a bitch to sharpen
[22:26:48] <pfred1> I can see why people use the spiral carbide heads
[22:27:21] <MattyMatt> the ones with spirals of normal rhombic inserts?
[22:27:25] <pfred1> yes
[22:27:33] <MattyMatt> yeah they look good
[22:27:45] <pfred1> after sharpening steel blades they sure do
[22:28:08] <MattyMatt> can you buy HSS inserts?
[22:28:25] <MattyMatt> like in the same shapes as carbide?
[22:28:45] <pfred1> I don't see why anyone would want to
[22:28:57] <MattyMatt> for woodwork
[22:28:57] <pfred1> not when you can get the pinnacle of materials
[22:29:21] <pfred1> spin it fast enough and carbide works good with wood
[22:30:00] <MattyMatt> it's true. my 4 flute carbide did all my wood cnc and was good as new until I tried it on alu
[22:30:05] <pfred1> though yes technically HSS gets sharper
[22:30:15] <pfred1> it just doesn't stay sharper
[22:30:56] <pfred1> with aluminum you need to use the right grade of carbide or all kinds of bad things can happen
[22:31:26] <MattyMatt> I broke a tooth off. chatter
[22:31:53] <MattyMatt> it's still sharp enough otherwise. it didn't last long enough to blunt it :p
[22:32:16] <pfred1> here's a picture of me destroying some carbide inserts http://i.imgur.com/T8CM5rk.jpg
[22:32:43] <pfred1> the face of that anvil is fucking hard!
[22:33:03] <pfred1> harder than a coffin nail
[22:33:13] <MattyMatt> I had an idea once to make a planer blade for inserts, then make the inserts in steel. upgrade to carbides when I can afford them. there looked like 100 on the one I saw
[22:33:50] <pfred1> I did get the top of that anvil like a mirror though
[22:35:19] <MattyMatt> coulda used a cup stone, if you don't mind grinding on the mill
[22:35:34] <MattyMatt> carbide chips are probably as bad as grit in the ways
[22:35:49] <pfred1> yeah I probably should have just ground the anvil with an angle grinder
[22:36:08] <pfred1> I didn't think it was as hard as it turned out to be
[22:36:13] <MattyMatt> on in the mill. keep it flat and level
[22:36:24] <MattyMatt> ^or
[22:36:27] <pfred1> I'm pretty good with angle grinders
[22:36:45] <pfred1> I basically power scrape with them
[22:37:15] <pfred1> between an angle grinder a sandign disc and a flap wheel I can get a flat mirrored surface
[22:37:30] <pfred1> oh and files to check for level
[22:37:35] <MattyMatt> I guess even cast iron gets case hardened if you hammer it for 100 years
[22:37:48] <pfred1> I don't know what that anvil is made out of
[22:37:57] <pfred1> but it's super hard
[22:38:15] <pfred1> it beat them carbide inderts up repeatedly
[22:38:31] <pfred1> I only have one good face left on them now
[22:38:42] <pfred1> they're 4 sided too
[22:39:16] <mike_LCNC> you guys know about servo tuning?
[22:39:28] <pfred1> I know it is out of my pay scale
[22:39:47] <MattyMatt> and mine. steppers I can help you with
[22:40:12] <pfred1> I understand some of the theory of it
[22:40:30] <pfred1> you have to balance the seeking
[22:40:41] <pfred1> so the drive doesn't dither
[22:41:17] <pfred1> people that are good at it say there's nothing to it
[22:41:25] <pfred1> but they know what they're doing
[22:41:52] <pfred1> I got my giant vac leaf blower running like a top today
[22:42:40] <MattyMatt> I'd have it running like a furnace. I need a blower
[22:42:53] <MattyMatt> melt some of this puny scrap
[22:42:59] <pfred1> oh it burst into flames at one point it was rather exciting
[22:43:11] <pfred1> that was when I decided to put it away
[22:43:36] <pfred1> for a minute i thought she was gonna blow
[22:44:11] <MattyMatt> I think I'm gonna need an electric oven for melting alu here at mommas. she'll suppress any attempts to do it with fire
[22:44:13] <pfred1> the muffler is right over the gas tank
[22:44:44] <pfred1> I've melted aluminum
[22:45:25] <pfred1> I made one of them fancy furnaces but after having done it I bet you could melt aluminum on a campfire
[22:45:46] <pfred1> in fact I know you can because we've done it
[22:46:37] <pfred1> some drunk threw some lawn chairs into our campfire at Unadilla and the next day I pulled this blob of aluminum out of the ashes
[22:47:06] <pfred1> I kept it as a souvenir
[22:47:24] <MattyMatt> alu melting point isn't much more than glass
[22:47:38] <pfred1> it is 1,200F or thereabouts
[22:47:49] <pfred1> I've melted glass in a campfire too
[22:47:54] <MattyMatt> and it's lower than nichrome
[22:48:09] <pfred1> jack daniels bottle
[22:48:25] <MattyMatt> 3kW of electric nichrome should melt a small iron pot of soda cans
[22:48:29] <pfred1> I did that camping in upstate Maine
[22:49:17] <pfred1> soda cans are tough t omelt down
[22:49:33] <pfred1> they burn up to nothing because of their surface area
[22:49:40] <MattyMatt> at a squat I lived at for a while beer bottles were thrown in the firplace all the time
[22:49:46] <pfred1> once you got a puddle you push them in and that helps
[22:50:04] <MattyMatt> we had the chimney on the at glowing red sometimes. set the roof alight more than once
[22:50:47] <pfred1> fire is fun
[22:50:52] <MattyMatt> I was thinking of putting an vacuum lid on my pot
[22:51:16] <MattyMatt> alu can't burn if there's no air
[22:51:33] <pfred1> the oxygen is in the metal
[22:51:36] <MattyMatt> gotta burn the paint off first tho
[22:52:17] <pfred1> pushing them under does the trick
[22:52:56] <MattyMatt> so I'll start with alloy casting to get a puddle
[22:53:14] <MattyMatt> hard drive or something
[22:53:18] <pfred1> the best aluminum to cast with is castings
[22:53:25] <MattyMatt> yep
[22:53:27] <pfred1> cans are pure aluminum
[22:53:34] <pfred1> so kinda crappy
[22:53:57] <MattyMatt> and oxide and plastic and paint :p
[22:54:03] <MattyMatt> but free
[22:54:05] <pfred1> I want to do a melt and throw in some new pennies
[22:54:20] <pfred1> that should make Zamak
[22:54:31] <pfred1> because pennies are copper plated zinc today
[22:54:55] <MattyMatt> copper plated steel here now
[22:55:53] <pfred1> they were taking pennies and using them for ship ballast then casting ingots on the beaches of Africa
[22:56:06] <pfred1> when they were copper
[22:56:12] <Crom> zamak works great.. Look at all the Atlas and craftsman lathes
[22:56:40] <pfred1> yeah Zamak has a decent rep as a casting material
[22:56:58] <Crom> decent gears...
[22:57:00] <pfred1> the copper goes into solution in it
[22:57:15] <pfred1> you don't have to come up to the melting point of copper to make it
[22:57:38] <Crom> cans are crap for casting... for extruding they're great
[22:57:59] <pfred1> there's a neat youtube video about making aluminum cans
[22:58:09] <pfred1> the engineer guy or something
[22:58:12] <MattyMatt> they've got lead in them I think, to make them more ductile
[22:58:20] <Crom> tomorrow I finally get my eyes tested for a new prescription
[22:58:20] <pfred1> cans?
[22:58:42] <pfred1> I don't need ot get tested to know I'm slowly going blind
[22:58:42] <Crom> AL sodapop cans
[22:59:11] <pfred1> I've heard cans are pure aluminum
[22:59:18] <Crom> eyes are focussing futher out every year...
[22:59:32] <pfred1> that's what happened to me if it is within arms reach I can't see it
[22:59:54] <MattyMatt> I thought my eyesight was getting bad, until I tried daylight
[23:00:03] <pfred1> it is the damndest thing because it kind of looks like I can still see
[23:00:17] <pfred1> yeah and i need more light now than I used to
[23:00:18] <Crom> I can with glasses looking through the bifocals. Can't see shit since it's at the end of my reach
[23:00:31] <pfred1> I use reading glasses
[23:00:45] <MattyMatt> I'm still shortsighted
[23:00:47] <pfred1> and i have them visor magnifyers for small work
[23:00:53] <Crom> everytime I go to IKEA I get another $0 LED desk light
[23:01:03] <Crom> $10 or $12
[23:01:06] <MattyMatt> cocodamol fucked up my near sight
[23:01:18] <pfred1> I just got one of them fluroescent ring arm magnifiers like I always wanted
[23:01:31] <pfred1> I picked it up a yard sale for $5
[23:01:36] <MattyMatt> I like my big glass. 2x magnification and full stereo
[23:01:53] <pfred1> I'm really into my optics now
[23:01:59] <MattyMatt> 5" glass. no ring light
[23:02:14] <pfred1> hmm i never measured it
[23:02:22] <Crom> I'm looking for one... I also want to get the magnafiers from Harbor Fright that you wear on a head band
[23:02:42] <MattyMatt> I got a 4" one on an arm with a light, but the glass has a flat spot so it really fucks up stereo
[23:02:47] <pfred1> 4.6 inches
[23:03:25] <Crom> Explorer Steve on youtube had them in his last video making a cover for his RV matress
[23:04:08] <pfred1> Crom that's that I got a HF magnyfing visor
[23:04:13] <mike_LCNC> I just cant get it to settle////
[23:04:16] <Crom> my wife is short sighted, but it's getting out to normal distance now
[23:04:24] <pfred1> when you get one sew a towel on the headband
[23:04:41] <pfred1> because the vinyl is nasty
[23:04:43] <Crom> I use a piece of IKEA sheep skin
[23:05:01] <MattyMatt> I got one of those stupid chinese loupe ones. you can't point both eyes at the same place in focus, so it's pointless
[23:05:03] <pfred1> that'll work
[23:05:03] <Crom> old welders trick
[23:05:29] <pfred1> the HF visor works at least with one lens down
[23:05:46] <pfred1> with both down I don't like it
[23:06:26] <Crom> I've been using the HF clip on lens.. for soldering... can only use 1 eye
[23:06:36] <pfred1> I got one of the mI don't like it
[23:07:00] <pfred1> heck I don't even know where it is right now
[23:07:26] <pfred1> oh there it is
[23:07:38] <MattyMatt> 4k screen. 4k camera. macro lens. win
[23:08:12] <pfred1> I have another magnifying glass on an arm I made for soldering
[23:08:21] <MattyMatt> and micromanipulators for soldering
[23:08:37] <MattyMatt> waldos and lasers
[23:08:55] <Crom> I also have one of the 15meter 7mm usb camera's... that works pretty good for helping solder as well
[23:10:20] <MattyMatt> shit nearly 5am
[23:10:39] <MattyMatt> using my table saw in the morning. need sleep
[23:10:56] <pfred1> nite
[23:11:09] <MattyMatt> gn
[23:11:47] <pfred1> here's my electronics soldering station http://i.imgur.com/ko1RYQU.jpg
[23:12:07] <pfred1> with my arm magnifier there
[23:12:22] <pfred1> I put the other one over my other desk wing
[23:13:25] <pfred1> now i use the visor
[23:14:13] <pfred1> I should see what reading glasses, the visor, and the magnifying glass is like
[23:14:59] <pfred1> it is a really short field of focus
[23:21:07] <Crom> pfred1, I have 2 of those weller's... The connectors from the iron to the base really suck...
[23:21:47] <Crom> I think I'm just going to solder the wires together...
[23:21:49] <pfred1> yeah mine it looks like someone monkeyed with it
[23:21:53] <renesis> does that use the magnetic tips?
[23:22:04] <pfred1> I got it in a box of junk at a flea market for $10
[23:22:06] <renesis> i cant stand those things
[23:22:08] <pfred1> yeah
[23:22:09] <Crom> renesis, yeah for the temp control
[23:22:24] <renesis> they stuck on or off, and the fix is banging them against the bench
[23:22:33] <pfred1> it is the same iron I used when I was assembling electronics at a board house
[23:22:46] <renesis> straight silly compared to hakko regulated stuff
[23:22:47] <Crom> good to know... I have one sticking on
[23:22:47] <pfred1> mine works OK
[23:23:08] <renesis> crom: im pretty sure banging wont make the situation any better long term
[23:23:16] <renesis> but yeh itll get it regulating again
[23:23:22] <Crom> pfred1, mine could have been from that board house
[23:23:37] <pfred1> you get it in New Jersey?
[23:23:44] <renesis> pretty sure all the ones ive used were left over from factory assembly lines
[23:23:46] <Crom> San Jose
[23:23:58] <pfred1> place I worked was in Jersey
[23:23:59] <Crom> surplus... they have numbers melted into them
[23:24:32] <pfred1> no way that joker is still in business today
[23:24:49] <Crom> I got mine 20 years ago
[23:24:58] <Crom> 2 for $30
[23:25:17] <pfred1> no way he's still going?
[23:25:31] <Crom> actually 3 for $45... pops still has one.. I got my brothers back cuz it was sticking
[23:25:42] <pfred1> it looks like he's working out of his house now
[23:26:55] <pfred1> yeah we'd turn the irons on in the morning and let them just run all day
[23:27:32] <pfred1> day in, day out
[23:28:21] <pfred1> once a year for Christmas if you were really good you'd maybe get a new tip
