[00:27:18] <tiwake> XXCoder: you there?
[00:27:27] <XXCoder> yeah
[00:27:31] <XXCoder> whats up
[00:27:51] <tiwake> XXCoder: back from texas
[00:28:05] <XXCoder> how was texas and made decisions?
[00:28:14] <tiwake> not officially yet
[00:29:25] <tiwake> I'm just tired I guess
[00:29:36] <XXCoder> flight does take lot of energy
[00:29:43] <tiwake> I think tomorrow I'll give a 2-3 notice
[00:30:00] <tiwake> week
[00:33:07] <mikeh> what are some major changes in 2.8?
[00:33:58] <XXCoder> tiwake: cool. :)
[00:56:27] <Cromaglious_> ugh... waiting for nylon 3mm screws and standoffs from china... ugh... toooo slow....
[00:57:01] <Cromaglious_> been working on this yoocnc to THB6600 driver conversion for over 3 months
[01:03:40] <Cromaglious_> hmm 2.2kw water cooled spindle 8K-24K rpm w/ VFD with ER20 collet $255
[01:04:11] <enleth> Cromaglious_: there was someone with a yoocnc control here a few hours ago asking for help/advice
[01:04:22] <enleth> that's ai6ci, still there
[01:04:49] <Cromaglious_> I could set up some V blocks and mill off the 65mm holder
[01:05:00] <Cromaglious_> ai6ci, you there?
[01:05:03] <enleth> you might want to share what you learned I guess
[01:05:17] <Cromaglious_> that it's complete crap.. sure
[01:05:38] <enleth> the VFD seemed reusable
[01:06:05] <enleth> for what it's worth
[01:06:09] <Cromaglious_> bad isolation, crappy opto isolator design, and the THB6560 drivers are pure crap
[01:06:21] <Cromaglious_> I don't have the VFD in mine...
[01:07:12] <Cromaglious_> I'm about to put in a MKS board and use marlin
[01:11:06] <Cromaglious_> on my yoocnc PW3618 power supply board, I basically just use it for a bridge rectifier and smoothing caps only.. got a separate DC spindle controller
[01:12:26] <Cromaglious_> the 18v side puts out a decent 24vdc for the BOB and the THB6600 boards, as well as a 7812 and a 7805 for some logic
[01:18:39] <Cromaglious_> nite all
[03:15:32] <XXCoder> https://www.youtube.com/watch?v=Gme8sNpMNRw
[03:15:36] <XXCoder> very interesting iea
[03:21:14] <archivist> screws will strip out the pipe
[03:22:40] <XXCoder> I guess evenually
[03:22:47] <XXCoder> but then 40 cent each lol
[03:22:55] <XXCoder> handles are reusable
[03:31:33] <XXCoder> archivist: it'd be interesting to test different materials pipes (flexiable ones)
[03:31:38] <XXCoder> like steel pipe
[03:34:20] <archivist> at testing stage you come to the conclusion bought ones are better for the job
[04:12:51] <enleth> archivist: that should last a bit more if you used bolts with washers instead of wood screws
[04:13:15] <enleth> a nice trick if you need more clamps *now* due to a planning mistake and can't just fetch some from a store
[04:25:19] <XXCoder> yeah
[04:25:30] <XXCoder> and have some length of pvc pipe
[04:25:51] <XXCoder> its great for wood shop so 100% chance almost of having some wood
[04:42:31] <enleth> XXCoder: I have plenty, comes in useful for a variety of things
[04:45:13] <XXCoder> yeah?
[04:45:19] <XXCoder> whats ses you used pvc for
[04:45:22] <XXCoder> *uses
[04:51:45] <enleth> cylindrical containers for long stuff like allthread, welding rods, small round stock, etc., standoffs and enclosure parts for prototyping, low pressure differential air/vacuum ducts, resin casting mold containers
[04:52:52] <enleth> basically any stuff where a pre-made easily worked cylinder of moderate strength is needed
[04:58:20] <XXCoder> ahh nice
[05:52:12] <jthornton> morning
[05:52:40] <XXCoder> hey
[06:13:59] <Deejay> moin
[06:15:09] <XXCoder> hey
[09:17:15] * KreAa awaits his 4'th axis
[09:17:23] <KreAa> The plan is ready
[09:17:26] <KreAa> http://i.imgur.com/QLkD9j0.jpg
[09:17:36] <KreAa> Will install a baseplate in the tub
[09:17:50] <KreAa> and seal it as I bolt it to the intermediate plate
[10:00:12] <hatch789> Hi guys
[10:07:13] <archivist> we dont bite!
[10:07:52] <_methods> run away
[10:13:06] <CaptHindsight> https://www.crowdsupply.com/sutajio-kosagi/the-essential-guide-to-electronics-in-shenzhen
[10:15:35] <CaptHindsight> helpful idea ^^^
[10:16:03] <CaptHindsight> https://www.crowdsupply.com/eoma68/micro-desktop
[10:16:16] <CaptHindsight> crazy person project ^^^^
[13:00:51] <Erant> CaptHindsight: bunnie's a friend of mine, he really knows what he's talking about when it comes to Shenzen
[13:21:17] <awestleUCD> hello
[13:46:51] <Frank_12> ho?
[13:46:51] <Frank_12> hi?
[13:49:18] <awestleUCD> hi frank
[14:31:10] <CaptHindsight> Erant: I shop there myself
[14:31:59] <CaptHindsight> he designed that laptop that wasn't a laptop
[14:32:08] <CaptHindsight> clever
[14:33:48] <gregcnc> The table on this 3d printer...https://www.youtube.com/watch?v=6_YW22y8tgg
[14:35:16] <gregcnc> https://techcrunch.com/2016/07/10/whatever-happened-to-3d-printing/
[14:36:29] <CaptHindsight> that design should be able to use pellets and be able to choose from thousands of thermoplastics but.........
[14:36:44] <CaptHindsight> it doesn't
[14:37:42] <CaptHindsight> https://www.crowdsupply.com/sutajio-kosagi/novena laptop that's not a laptop
[14:39:29] <gregcnc> I like the wood case
[14:39:48] <CaptHindsight> the article should be more properly titled "Whatever happened to FDM printing?"
[14:41:29] <gregcnc> hot this week around here
[14:43:05] <CaptHindsight> was just out, not fun
[14:44:11] <gregcnc> strangely, virtually no mosquitoes so far
[14:44:14] <CaptHindsight> "3D printers aren’t incredibly complicated, but they have lots of moving parts that like to wear out over time and break." sheer genius that Gartner
[14:44:37] <t12> meanwhile the linotype...
[14:44:42] <CaptHindsight> gregcnc: go north 20-30 miles
[14:45:41] <CaptHindsight> if only we had built our printers without moving parts!
[14:46:26] <CaptHindsight> I hear that the best of the best CNC machines have no moving parts
[14:47:01] <yasnak> ha
[14:47:25] <gregcnc> maybe the parts in the inexpensive one aren't intended to last more your attention span
[14:47:56] <yasnak> well, best stock up on adderall then eh
[14:47:57] <_1SheYode> are the extents of the program shown in axis exposed via a pin?
[14:49:28] <CaptHindsight> and by CNC machine I mean not a CNC machine
[14:50:19] <malcom2073> Lol not complicated, just a lot of little parts.
[14:50:26] <malcom2073> So.... complicated.
[14:51:28] <DaViruz> to be fair he did say "incredibly complicated"
[14:52:17] <CaptHindsight> mildly complicated would be disingenuous
[14:52:46] <CaptHindsight> personally I always liked wickedly complicated when in New England
[14:57:13] <CaptHindsight> "I have reviewed exactly one 3D printer that didn’t break or develop a mysterious software issue within days of use."
[15:06:02] <SpeedEvil> hah
[15:06:24] <renesis> sounds about right
[15:19:42] <MarkusBec> mail
[15:26:37] <Flipp_> noob question about a lathe:
[15:27:12] <Flipp_> I've got an m4x20 screw that I need to shorten to m4x13
[15:27:32] <Flipp_> what's the best way to hold a screw in the chuck? If I just clamp it directly the screw tends to break a few seconds into trying to part
[15:28:14] <CaptHindsight> does it break where you are parting it or?
[15:28:39] <Flipp_> yeah, basically it breaks no matter what I do
[15:28:40] <SpeedEvil> one screw?
[15:28:42] <gregcnc> turn a piece of stock with a tapped hole for the screw, mount it in the chuck with the head toward the spindle
[15:28:59] <SpeedEvil> clamp it in a vice, and chop it off with a junior hacksaw
[15:29:02] <Flipp_> if I try to part it directly, it shears off somewhere up the threads
[15:29:13] <Flipp_> and if I try to turn the threads down, it eventuallly fails
[15:29:16] <gregcnc> made of cheese or?
[15:29:25] <Flipp_> speedevil: yeah, that's what I ended up doing :)
[15:29:26] <SpeedEvil> Or just grind it off
[15:29:45] <Flipp_> gregcnc: thanks, good idea. I'll look into that for future projects
[15:30:04] <Flipp_> speedevil: yeah, I can do that now that I've got a bench grinder
[15:30:16] <CaptHindsight> https://www.youtube.com/watch?v=f8UwifeNx3M Screw Cutter
[15:30:37] <Flipp_> just figured there was some way to better hold the piece in a chuck
[15:31:24] <CaptHindsight> How to use a hacksaw https://www.youtube.com/watch?v=G0NGoPF3Q6A
[15:31:52] <Flipp_> capthindsight: I... wh... wow... I have had a pair of those for close to a decade and never even gave those holes a passing thought
[15:32:02] <Flipp_> ya learn somethin' new every day :)
[15:32:05] <gregcnc> I cut screws in the lathe, but in collets
[15:33:23] <Flipp_> gregcnc: do you hold them by the head or the thread?
[15:34:16] <gregcnc> thread unless they are long and the collet is too deep, then I use the threaded stock trick
[15:36:00] <Flipp_> cool, thanks!
[15:37:23] <gregcnc> hmm trying to find a pin hook spanner locally http://www.samstagsales.com/images/amf54973.jpg
[15:37:41] <Flipp_> where's "locally"?
[15:37:57] <gregcnc> nw of chicago
[15:38:16] <gregcnc> if all fails. mcmaster for $40 will have it tomorrow
[15:39:14] <JT-Shop> I like the adjustable ones better
[15:39:38] <gregcnc> this is tight, those look pretty thick
[15:46:26] <Flipp_> I'm (obviously) new-ish to machining, so this may be a dumb question but...
[15:47:00] <Flipp_> I've trammed my mill as good as I can get it, ~0.001 in x/y relative to the table
[15:47:39] <Flipp_> is it normal for a face-mill facing cut to look mirror finish when moving one direction in x, but look slightly off when going the opposite?
[15:48:08] <Flipp_> it looks almost as good in 6061, but it kinda looks like there might be a tiny bit of aluminum residue left on the face mill's inserts
[16:01:28] <t12> climb vs conventional?
[16:02:16] <XXCoder> t12: it shouldnt matter as long as going forward right side is open
[16:02:27] <XXCoder> otherwise dunno
[16:04:37] <Flipp_> xxcoder: that's the strange part: it's the going-forward-right-side-open pass that's slightly worse
[16:05:09] <Flipp_> I mean, nothing that a quick lap on an india stone wouldn't fix
[16:05:23] <XXCoder> strange. well unfortunately I gonna go work now. laters
[16:20:57] <Deejay> gn8
[17:05:56] <Flipp_> oh, one last question before I gotta jet: has anyone made one of those vise aligning aid? kind of like a gate that swings down to help align a workpiece to the vise's left hand edge?
[17:07:29] <Flipp_> the small piece bolted onto the left side of Tom's vise at 14:00 here: http://www.youtube.com/watch?v=vaeCqLDNyCo&t=14m0s
[17:32:45] <Frank_12> hi, someone knows for sure that this is the symbol of "auxiliary contact" ? https://www.google.com.ar/search?q=instant+operating+contacts+electric+components&rlz=1C1ASUC_enAR629AR629&espv=2&biw=1360&bih=667&source=lnms&tbm=isch&sa=X&ved=0ahUKEwjylfmHtOzNAhXCG5AKHSEfC-oQ_AUIBigB#tbm=isch&q=instant+operating+contacts&imgrc=UHAr4cjxP_6NnM%3A
[17:33:29] <Frank_12> i've only could found that it is an auxiliary contact or an instant operating contact,
[17:34:22] <Frank_12> and control terminals, 3 things for the same symbol
[18:12:54] <JT-Shop> what are you trying to sort out Frank_12 ?
[18:14:46] <Frank_12> actually, in the end i could understand the wiring diagram, i was reading some nfpa example of an industrial machine wiring diagram for power up etc, so yea, all good now :)
[18:15:14] <zeeshan|2> Frank_12: what just means normally open contact
[18:15:33] <zeeshan|2> you will have to label it
[18:15:44] <zeeshan|2> theres no specific symbol for it
[18:15:55] <zeeshan|2> what= that
[18:16:35] <Frank_12> yeah, i think thats why i found 3 explanations heh, it ended up beeing an auxiliary N.O. contact for powering up a relay with a momentary push button
[18:16:37] <Frank_12> thanks guys
[18:16:46] <zeeshan|2> hehe
[18:16:53] <zeeshan|2> that sounds like the manual bypass im working on at work
[18:17:07] <zeeshan|2> i have a interlock momentary switch that temporarily disables the buzzer
[18:17:10] <zeeshan|2> during servicing
[18:18:41] <Frank_12> yeah, it seems like another language to me having no background studies on the subject
[18:19:07] <Frank_12> learning i am. heh
[18:23:39] <JT-Shop> zeeshan|2: I flew the foamy today
[18:23:47] <zeeshan|2> foamy?
[18:25:38] <JT-Shop> http://www.twistedhobbys.com/TH-32-EPP-Edge-540-GH-RCF-32-Edge-540-GH.htm
[18:25:42] <JT-Shop> watch the video
[18:26:19] <zeeshan|2> wow
[18:26:21] <zeeshan|2> foamy is big

[18:28:22] <zeeshan|2> wtf
[18:32:47] <JT-Shop> I have not flown RC in 10 years or more... first flight was funny

[18:40:26] <ai6ci> I can't even fly knife's edge.
[18:41:29] <ai6ci> Granted I never put a lot of time into it. Not a marketable skill for me :)
[18:44:17] <JT-Shop> I used to like nose in hover at eye level with my xcell 60

[19:03:51] <SpeedEvil> English wheels are awesome
[19:04:13] <SpeedEvil> I have imagined a bastardised CNC version.
[19:05:01] <SpeedEvil> Take a flat sheet, clamp the edges - now run around a pattern starting from the middle of any depth features pushing the metal into them, while retaining the rest of teh sheet flat
[19:05:19] <malcom2073> https://www.youtube.com/watch?v=Wl5_wUVxRvw
[19:05:21] <malcom2073> SpeedEvil: ^^
[19:05:35] <SpeedEvil> yeah - related to that
[19:06:01] <SpeedEvil> ^exactly
[20:03:42] <ai6ci> Damn I work in the wrong industry.
[20:03:48] <ai6ci> That looks cool as all hel
[20:51:02] <Tom_itx> BeachBumPete, any closer to being 'home' ?
[20:54:06] <BeachBumPete> Oh sorry man I was watching TV LOL
[20:54:23] <Tom_itx> np, about to go take a breather myself
[20:54:32] <BeachBumPete> yeah we are SUPPOSED to be closing Friday but the government paperwork is just ludicrous.
[20:55:15] <BeachBumPete> I went by the house today and inspected what the seller had done and it appears he has been taking care of a lot of the little problems the house had so that was nice.
[21:23:54] <zeeshan|2> hi tom
[21:23:54] <zeeshan|2> :D
[21:25:52] <Tom_itx> whassup?
[21:26:00] <zeeshan|2> not much
[21:26:02] <zeeshan|2> whats going on
[21:26:12] <Tom_itx> workin on the well tonight
[21:26:17] <Tom_itx> today*
[21:26:23] <zeeshan|2> digging?
[21:26:31] <zeeshan|2> *drilling
[21:26:37] <Tom_itx> no i had to flush it out
[21:26:42] <zeeshan|2> why
[21:26:45] <Tom_itx> it's an old sandpoint
[21:26:53] <Tom_itx> because it was gettin plugged up
[21:27:09] <Tom_itx> and i didn't feel like pulling it
[21:27:11] <zeeshan|2> i always wondered
[21:27:15] <zeeshan|2> whenever your motor is pulling water
[21:27:23] <zeeshan|2> does it go thru a filter or something
[21:27:27] <zeeshan|2> to remove the dirt
[21:28:05] <Tom_itx> no
[21:28:27] <Tom_itx> the fine sand goes thru the system
[21:28:36] <Tom_itx> it's just for watering anyway
[21:28:42] <zeeshan|2> o
[21:28:46] <Tom_itx> otherwise i'd have filters on it yes
[21:29:44] <Tom_itx> first i flushed it out and got alot of sand out then i backflushed it
[21:29:56] <Frank_12> is it wrong to wire the Estop to latch an electromechanical relay that switches off the contactors for the motors, etc, from a 24vdc source?? (relay 24vdc coil ofcourse)
[21:30:24] <zeeshan|2> no
[21:30:40] <zeeshan|2> thats called a safety relay usuallyu
[21:30:48] <Frank_12> okey thanks :)
[21:31:40] <Frank_12> because i see on example wiring diagrams that they use relays with 220v coils to wire the estop
[21:32:47] <zeeshan|2> i really dislike high voltage going thru a a switch youre youd be touching!
[21:33:23] <Tom_itx> dammit, none of these brightsticks are dimmable...
[21:34:15] <Frank_12> very true, and even if the switching dc power supply goes nuts, and turns the output power off, then everything goes off aswell
