[00:01:09] <Simonious> http://www.timgoldstein.com/cnc/GeckoG320Wiring.pdf this is nice
[00:02:26] <pfred1> I need a new PSU
[00:02:46] <pfred1> well I'm going to need one
[00:04:16] <Cromaglious_> I'm ordering a 24v one when I can... this 27v is working.. 57v for the spindle... over specs as well
[00:04:29] <Cromaglious_> that'' be getting a 48v
[00:04:49] <pfred1> ideally I could use a 40V supply but no one makes those
[00:04:57] <Cromaglious_> that wolfmanjm on #smoothieware is an ass
[00:05:03] <pfred1> so I'm going to have to settle for say a 36V
[00:05:19] <Cromaglious_> get a 40v and tweak the voltage reference
[00:05:25] <Cromaglious_> get a 48v and tweak the voltage reference
[00:05:40] <Simonious> Cromaglious_: yeah? I've heard good things about smoothieboard, but I haven't run one.
[00:05:48] <Simonious> I've got one.. just never hooked it up
[00:05:49] <pfred1> I'd like to avoid using a SMPS
[00:05:57] <Cromaglious_> the board is wonderful, wolfmanjm is an ass
[00:05:58] <Simonious> was tempted for this project, but I don't want to change user interfaces
[00:06:18] <pfred1> just a plain old xformer with a bridge and filter
[00:06:20] <Cromaglious_> he just rubs me wrong all over...
[00:06:29] <pfred1> meh don't let it get to you
[00:06:42] <pfred1> tech draws aspies
[00:06:57] <Cromaglious_> <wolfmanjm> Crom: so your abive example would be ack-grep ngc .<wolfmanjm> rather tahn that crap you use :)
[00:07:08] <Cromaglious_> 40 years of regex he calls crap
[00:07:28] <pfred1> peopel fear what they don't understand
[00:07:35] <Cromaglious_> if it works it's ain't broke
[00:07:48] <pfred1> that is not always true
[00:08:01] <Cromaglious_> think he's a HOA hitler in the making
[00:08:46] <Cromaglious_> if it works, it ain't broke, though it might be inefficient, or stupid looking
[00:09:03] <pfred1> I've had broke stuff work
[00:09:04] <LeelooMinai> Or make break in 5 minutes:p
[00:09:13] <LeelooMinai> may*
[00:10:15] <Cromaglious_> that's Ruperts corollary to Murphy's law... If it's supposed to not work, it will
[00:11:00] <Cromaglious_> yep hitler in the making
[00:11:02] <Cromaglious_> You have been kicked from #smoothieware by wolfmanjm (User terminated!)
[00:11:14] <pfred1> well that solves that problem
[00:11:16] <Cromaglious_> and banned
[00:11:44] <pfred1> what is #smoothieware?
[00:11:45] <LeelooMinai> #smoothieware... Is that channel active/interesting?
[00:11:45] <Cromaglious_> hmmm gotta look at the admin and find an old buddy, and have god speak to him
[00:11:58] <Cromaglious_> very active and interesting
[00:12:03] <LeelooMinai> Probably related to those smoothie boards
[00:12:15] <pfred1> OK what's a smoothie board?
[00:12:26] <Cromaglious_> oh yeah... you can't mention any MKS board either, he goes balistic
[00:12:29] <pfred1> I guess i could google it
[00:12:37] <LeelooMinai> It's stepper motor controller I think - everything on one board.
[00:12:44] <LeelooMinai> 4 axis and open hardware?
[00:12:45] <pfred1> ah ha
[00:12:46] <Cromaglious_> 100Mhz 32bit micro controller
[00:12:50] <Cromaglious_> 5 axis
[00:12:59] <Cromaglious_> 3,4, or 5
[00:13:13] <pfred1> how many amps a drive?
[00:13:15] <Cromaglious_> 4 and 5 channels have ethernet
[00:13:22] <LeelooMinai> It's kind of pricey but I saw that Chinese made $50 clone
[00:13:31] <pfred1> $50 is cheap enough
[00:13:34] <Cromaglious_> 2 i think, but you can drive externals
[00:13:39] <pfred1> 2?
[00:13:49] <Cromaglious_> $69
[00:13:56] <Cromaglious_> 2AMP
[00:13:57] <pfred1> that's the problem with those sorts of things they're always a bit underpowered
[00:14:28] <pfred1> 2 is borderline for CNC
[00:14:35] <Cromaglious_> easier to drive externals with + inputs for step, dir and enable
[00:14:37] <Simonious> yeah, you have to use an external driver
[00:14:42] <Simonious> to run a bigger machine
[00:14:48] <Simonious> but it's easy to bypass the onboard drivers
[00:14:49] <LeelooMinai> I think it's more meant for 3d-printers, maker contraptions, etc.
[00:15:05] <pfred1> Simonious then its not all in one anymore
[00:15:10] <Cromaglious_> yep...
[00:15:15] <Simonious> yep
[00:15:27] <pfred1> I run LinuxCNC off a PC that i picked up for $5
[00:15:29] <Cromaglious_> 2amps at 24v gets alot done
[00:15:32] <pfred1> hard to beat $5
[00:15:41] <Simonious> pfred1: yes!
[00:15:45] <Simonious> and linuxCNC kills it
[00:15:57] <Simonious> not that smoothieboard isn't nice
[00:16:03] * Simonious shrugs
[00:16:08] <pfred1> another $5 for a used monitor and away we go!
[00:16:08] <Cromaglious_> the ethernet is what I like.. I can just send a file through the browser
[00:16:26] <pfred1> my $5 PC has ethernet
[00:18:35] <pfred1> I have a nfs share mounted on it and i put files on it with that
[00:20:28] <pfred1> Cromaglious_ when I went from 24V to 28V the performance gain I got was substantial
[00:20:44] <pfred1> using TB6560 drives
[00:21:52] <Crom> I'm using TB6600
[00:21:55] <Crom> s
[00:22:03] <pfred1> I have those on order
[00:22:17] <pfred1> I ordered two different kinds
[00:22:25] <pfred1> I need to evaluate them see which I like better
[00:22:26] <Crom> the ones I have are common 5v.. little harder to run on the smoothie
[00:23:18] <Crom> need ones with + and - step, dir, enable
[00:24:09] <Crom> or common -
[00:24:56] <pfred1> I am interested to see just what I get
[00:25:22] <pfred1> each was like $9 and change
[00:25:27] <Crom> mine go to 32v, my BOB goes to 24v
[00:25:59] <pfred1> yeah the limiting factor on drives is usually the on board regulator
[00:26:17] <pfred1> because a TB6600 IC goes to 45V
[00:26:26] <Crom> and 4.5amp
[00:27:21] <pfred1> so you could swap out the regulator for a high voltage type
[00:27:33] <pfred1> and extend the board range
[00:27:47] <Crom> hmm need to get some white lithium grease... for my X,y,z screws
[00:28:07] <pfred1> I use self lubricating nuts
[00:28:25] <pfred1> they're HDPE
[00:28:37] <pfred1> to basically catalyzed oil
[00:28:44] <pfred1> so basically catalyzed oil
[00:29:20] <Crom> think I may just get a 6090 mechanical kit... 1.5kw spindle, vfd and a SX45 mill
[00:30:07] <Crom> now just gotta wait for money
[00:30:26] <pfred1> I just use a router as a spindle
[00:30:35] <pfred1> I have a Bosch Colt
[00:31:00] <pfred1> it plows through wood pretty good
[00:31:27] <pfred1> but i have crap for bits for it right now
[00:31:43] <pfred1> I have some of those on order too
[00:32:04] <pfred1> when i went to 1/2 collet routers I kind of stopped buying 1/4 accessories
[00:32:54] <pfred1> I also ordered some of those collet adapters too
[00:33:12] <pfred1> so I can run 1/8th shank tools in it
[00:34:18] <pfred1> I wish they made an ER11 collet on a 1/4 shank
[00:36:36] <Crom> routers are too damn load
[00:36:47] <pfred1> yeah I know mine is
[00:36:55] <Crom> I want a 1.5KW with an ER20 collet...
[00:37:22] <Crom> go up to 1/2 or 9/16 in a special
[00:37:26] <pfred1> the way i see it I am going to be doing small work like engraving
[00:38:20] <Crom> I have some 0.008 and 0.025" end mills
[00:38:46] <pfred1> I bought some V points and ball end mills
[00:39:22] <pfred1> I got a RF-32 mill/drill
[00:39:35] <pfred1> I run like a 2" shell mill on it
[00:39:48] <pfred1> in steel
[00:40:22] <pfred1> different machine for different work
[00:40:28] <Crom> round column?
[00:40:32] <pfred1> yes
[00:40:41] <pfred1> it's the HD model though
[00:40:48] <Crom> I want a square column
[00:41:08] <pfred1> meh the round comes in handy and as long as you plan your job out the round isn't a problem
[00:41:42] <Crom> mount a laser pointer on the head.. when you get it trammed in turn on the laser and mark the wall where it hits if the base is bolted bown
[00:42:11] <pfred1> yeah I tried that
[00:42:30] <Crom> gets you close
[00:42:40] <pfred1> just don't move the head
[00:42:56] <Crom> true dat...
[00:43:16] <pfred1> though I've used center punches to line it back up
[00:43:38] <Crom> heh...
[00:44:12] <pfred1> the spud is your friend
[00:44:20] <pfred1> spuddy buddy!
[00:45:00] <pfred1> that's one way i line up for drilling holes I unlock the head and put a spud in the chuck
[00:45:13] <pfred1> put it down in the punch hole then lock the head
[00:45:39] <pfred1> beats trying to do it by eye
[00:45:50] <Crom> damn... gotta send a letter to D.C. keep forgetting to write it
[00:47:37] <Crom> A new claim was submitted while an existing claim is pending. New information was found and consolidated with the pending claim. The new claim is now marked as Complete in Historical Claims with no further action required.
[00:48:09] <Crom> hmmm I still have an existing claim back to 2008 pendind.. so my exfective date goes back to then?
[00:49:31] <pfred1> Crom what square column mill were you thinking about getting?
[00:49:44] <Crom> Bolton SX45
[00:50:19] <pfred1> I ain't coming up for anything with that
[00:50:20] <Crom> either that or a G0704
[00:50:28] <Crom> Bolton SX-45
[00:50:43] <pfred1> ah the griz came up
[00:50:55] <pfred1> it like a seig X3?
[00:51:26] <Crom> more life a RF-45
[00:52:17] <pfred1> woo they cost a chunk of change
[00:52:33] <pfred1> I got a genuine rong fu 4x6
[00:52:52] <Crom> oh Bolton ZX-45
[00:52:58] <pfred1> that saw has been through hell and back again
[00:53:34] <pfred1> that'll do the job
[00:54:38] <Crom> Rong Fu is some quality kit.. the Tawanise stuff
[00:54:46] <pfred1> doesn't spin very fast goes pretty low though
[00:55:25] <Crom> good for steel
[00:55:39] <Crom> will have the 6090 for light stuff
[00:56:10] <pfred1> I run my mill at like 950 RPM so much
[00:56:17] <Crom> also want to get a lathe that'll do over 36" between center
[00:56:29] <Crom> what size bits?
[00:56:45] <pfred1> that is good for like 1/4 twist drills
[00:56:53] <Crom> but $1700 for a ZX45 ain't bad
[00:57:06] <pfred1> shipped?
[00:57:15] <pfred1> because griz screws customers on shipping
[00:57:22] <pfred1> unless you pick it up
[00:57:40] <pfred1> I got my mill off HF for $800 to my door
[00:57:57] <pfred1> but it was years ago and it was a scratch and dent special
[00:58:25] <Crom> gotta be careful with HF... may try to stick you with ship to door when you request ship to store
[00:58:38] <pfred1> thre was something wrong with the start contacts i nthe motor but I fixed it
[00:58:57] <pfred1> they were just bent up some
[00:59:48] <pfred1> I got my mill before they had their chain of stores
[01:00:05] <pfred1> like back in the early 90s
[01:01:41] <pfred1> here's me being cruel to my 4x6
http://i.imgur.com/YvLQO.jpg
[01:02:08] <Crom> umm HF has been around since '67 and I remember going into the store in the '80s
[01:02:18] <pfred1> yeah in cali
[01:02:37] <pfred1> they did not have a nationwide chain until much later
[01:02:41] <Crom> ahhh
[01:02:58] <pfred1> I'm going to say the late 90s or early oughts?
[01:03:09] <pfred1> they had like 2 stores on the west coast
[01:03:18] <pfred1> other than that it was all mail order
[01:03:57] <pfred1> my saw has a date code of 92 on it
[01:04:02] <Crom> I was in Misouri when Grizzly started I remember their ads in '83 or '84
[01:05:04] <pfred1> grizzly too rich for my blood
[01:05:17] <Crom> yeah rather have the bolton.... bigger table
[01:05:25] <Crom> only $500 more
[01:05:32] <Crom> w/ shipping
[01:06:10] <pfred1> I forget how big the table is on my mill but I think the longest cut I've ever done on it is like 12 and 1/2 inches?
[01:06:24] <pfred1> under the head travel is weird
[01:06:40] <pfred1> it ain't the whole taqble that's for sure
[01:07:48] <pfred1> that and if you want to do decent work you need a decent vise just a drill vise don't cut it you need a real mill vise
[01:08:39] <pfred1> with crappy vises the jaw pops up and your work goes out of square
[01:08:46] <LeelooMinai> $1k Kurt vise minimum of course:p
[01:09:10] <pfred1> I bought a beater at a flea market for $20 myself then I fixed it up
[01:10:02] <pfred1> but i had t oremachine the whole thing it was really shot up
[01:11:00] <pfred1> works good on my mill though
http://i.imgur.com/pDAid.jpg
[01:11:20] <pfred1> it was stripped and the jaw was cracked
[01:11:21] <Crom> hmmm $3400 all told, with clamp kit, vice, rotary table, stand, collet set, face mill and shipping
[01:11:34] <pfred1> yeah I don't have a rotary table
[01:11:56] <pfred1> I got a collet jig but I don't have a collet set for it yet either
[01:12:10] <pfred1> a 5C index holder
[01:12:37] <pfred1> you need parallels too
[01:12:51] <pfred1> get the thin ones
[01:13:05] <Crom> 5C indexer and the square and hex blocks
[01:13:26] <Crom> not square.. octagonal
[01:14:01] <pfred1> I used to make these
http://i.imgur.com/OZa5EkO.jpg
[01:14:05] <pfred1> I made that one in fact
[01:14:37] <pfred1> that's a J&S Tool downholding clamp
[01:14:58] <pfred1> I should have stolen a lot more of those while I was working there
[01:15:14] <pfred1> one of their wheel dressers too
[01:15:42] <pfred1> but I was at a yard sale and someone was selling some of their clamps
[01:15:47] <pfred1> so I had to buy them
[01:15:47] <Crom> sitting here twiddling my thumbs, oh and chrome just crashed
[01:16:03] <Crom> and it's up again...
[01:16:07] <Crom> waiting waiting
[01:16:10] <pfred1> I use FF
[01:16:29] <pfred1> I have Chromium installed but i just don't like it
[01:16:29] <Crom> OH NICE! I love those ChrisB has some
[01:16:40] <pfred1> J&S clamps?
[01:16:43] <Crom> this is an old 32bit chrome install
[01:16:58] <Crom> could be or similar action
[01:17:02] <pfred1> they're wicked expensive
[01:17:27] <pfred1> that little clamp is probably like $100
[01:17:30] <Crom> they'll be my first dovetail project
[01:17:33] <pfred1> madei nthe USA and all of that
[01:17:47] <pfred1> heh we broached that
[01:17:59] <Crom> again it's $100
[01:18:15] <pfred1> I know exactly how that clamp is made becausei used to make them by the thousands
[01:18:31] <pfred1> it ain't worth making just a couple
[01:18:32] <Crom> then I'll have to get a sine table, and a gauge block set
[01:18:53] <pfred1> heck I used to throw out like 4 or 5 with every operation setup
[01:19:19] <pfred1> that's the secret of machining
[01:19:27] <pfred1> make 10X as many as yo uactually want
[01:19:38] <Crom> hence $100
[01:19:47] <pfred1> yup
[01:19:51] <pfred1> we used to throw out so much
[01:20:14] <pfred1> there's the one you'er buying then the 10 in the scrap dumpster that you're paying for too
[01:20:47] <pfred1> with these it wasn't that bad but the dressers it was bad
[01:21:01] <Crom> hmm cap screw is captive...
[01:21:06] <pfred1> we might get 100 out of a run of 1,000
[01:21:16] <Crom> why so bad?
[01:21:20] <pfred1> it is a ser screw i nthe nose
[01:21:22] <pfred1> set
[01:21:45] <pfred1> the nose just has a pocket and the body has a half a thread
[01:21:45] <Crom> all manual? no cnc?
[01:21:58] <pfred1> well the rotary tables we CNCed
[01:22:08] <Crom> so the screw is a flat top 70% thread?
[01:23:06] <pfred1> that nose screw is just a set screw
[01:23:07] <pfred1> there a pocket milled into the nose that it sits in
[01:23:07] <pfred1> lkike a half moon cut out
[01:23:08] <Crom> grub screw with flat bottom and top?
[01:23:18] <pfred1> yes
[01:23:29] <pfred1> it really is brilliant
[01:23:43] <pfred1> we'd tap them two at a time
[01:23:46] <pfred1> the bodies
[01:23:57] <pfred1> put them butt up against each other
[01:24:14] <Crom> so output could have been 90/100 if they cnc'd everything?
[01:24:25] <pfred1> probably not
[01:24:44] <pfred1> you still got to setup CNC machines
[01:24:56] <pfred1> that's where you lose parts setting up
[01:25:21] <Crom> once your fixtured...
[01:25:48] <pfred1> you can't just leave the fixtureso n the machines
[01:25:59] <Crom> my dad's an industrial engineer...
[01:26:31] <Crom> he's setup lines... and had them buy 20 machines to do one op each
[01:26:48] <pfred1> yeah we couldn't afford to do that
[01:27:06] <pfred1> heck we were running machines from like 1895
[01:27:08] <Crom> if output was 90/100 they could
[01:27:29] <pfred1> we had a horizontal mill that old
[01:27:48] <pfred1> but it was beautifu lall hand scraped
[01:27:55] <Crom> anything more than a 3% reject he'd fix
[01:28:05] <Crom> the problem
[01:28:07] <pfred1> no way was he gonna fix our broach
[01:28:16] <pfred1> no possible way
[01:28:35] <pfred1> thre were like 3 people in the whole world that knew how that hting worked andthey all died long ago
[01:29:14] <pfred1> it had hydraulic logic
[01:29:15] <Crom> probably he'd mill the slot, cut to 0.010" on the dove tail then broach the rest
[01:29:33] <Crom> he's good at that
[01:29:33] <pfred1> no electronics at all
[01:29:48] <pfred1> it was a rats nest of hydraulic lines
[01:29:53] <Crom> he was a jouryman machinist at 15
[01:30:14] <pfred1> there was plenty of talent in that shop too
[01:30:28] <pfred1> but everyone knew not to mess with the broach
[01:30:35] <pfred1> just let it do what it does
[01:30:35] <Crom> grandpa was superintendent of Machine shop at kaiser richmond ship yard #2
[01:31:15] <Crom> he's setup screw machines from scratch
[01:31:34] <Crom> then again he's 76 now
[01:33:11] <pfred1> we made these too
http://d2ydh70d4b5xgv.cloudfront.net/images/3/6/j-s-grinding-wheel-dresser-fluidmotion-model-f6549-excellent-condition-e00a89fb8a923624332ac739da01ec3e.jpg
[01:33:26] <pfred1> that unit right there that's like $4,000
[01:34:43] <pfred1> the spec is 0.001 but if the needle moved on a tenths indicator we wouldn't ship it
[01:34:43] <Crom> I believe it..
[01:35:05] <pfred1> so pretty much we held it to 0.00005
[01:35:41] <pfred1> you'd test it by putting a carbide ball where the diamond goes and sweepign the unit
[01:35:46] <Crom> as my granddad would say... the thickness of a skidmark on a gnats ass
[01:36:16] <pfred1> yeah those it took a lot to make one right
[01:36:35] <pfred1> like the way the rotating base is graduated
[01:36:44] <pfred1> you don't want to know how that is done
[01:37:57] <Crom> almost looks like EDM
[01:38:16] <pfred1> nah it was a clockwork machine called a graduator
[01:38:32] <pfred1> had a point that would scratch the lines into it
[01:38:42] <pfred1> but setting the work on that machine was a bitch
[01:38:59] <pfred1> you had to eyeball it
[01:39:20] <Crom> so the place was full of old school crap, when the US rebuild germany and japan
[01:39:47] <pfred1> out horizontal band saw was a german war release piece
[01:39:48] <Crom> and then they never had money to upgrade
[01:40:05] <pfred1> mah what we had was good enough
[01:40:14] <pfred1> that saw would blow your mind
[01:40:26] <pfred1> it had hydraulic feed and it was dead nuts accurate
[01:40:40] <Crom> doh... it was war time german
[01:40:51] <pfred1> I'd load up the roller table with like 5 bars of steel
[01:41:05] <pfred1> clamp them together then just let it eat them all up
[01:41:26] <Crom> crankshafts on meshersmitz had tollerances of 0.000001"
[01:41:27] <pfred1> it'd grab the bars pull them in then drop down on them
[01:42:05] <pfred1> it could cut cold rolled steel like it was pine too
[01:42:20] <pfred1> we had like 6 TPI blade on it
[01:42:35] <Crom> blades? how long did they last??
[01:42:49] <Crom> or just get resharpened
[01:43:05] <pfred1> I don't remember us changing them very often
[01:43:19] <pfred1> not at all really I'd cut stock for days with that saw for big jobs too
[01:43:41] <pfred1> like if we were making 10,000 of something
[01:43:57] <pfred1> that's liek a week an op
[01:44:12] <Crom> cut 1,000,000 blanks?
[01:44:28] <pfred1> nah that would be the initial run 10,000
[01:45:11] <pfred1> be there all week drilling the same hole
[01:49:06] <Crom> sheeshz... spot, drill? spot, drill? or stubby drill and drill drill drill
[01:49:06] <pfred1> nah it'd be fixtured you'd just load the piece and drill it
[01:49:06] <pfred1> we had hydraulic vises
[01:49:06] <pfred1> so once you had it lined up you just drilled until the drill bit shattered
[01:49:06] <pfred1> we didn't bother to sharpen them or anything
[01:49:26] <Crom> wooo hooo Steam Powered Giraffe release Album 5 YEAH!!!!!!
[01:49:29] <pfred1> well sometimes we would but usually you'd jsut go until you split it up the spine
[01:50:21] <pfred1> wit hend mills i always knew when they were going to go because they'd start coughing up sand
[01:50:22] <Crom> hehe.. unlike some china crap I've had which got a little warm and twisted like butter
[01:50:47] <pfred1> then you knew that tool wasn't long for this world
[01:50:54] <Crom> din din back laterz..
[01:50:58] <Crom> nice...
[02:25:44] <Deejay> moin
[02:50:01] <Crom_> Moin Deejay
[02:50:27] <Crom_> yes I'm up late.. Steam Powered Giraffe released an album tonight.. YEA!!!
[05:35:32] <jthornton> morning
[05:47:20] <jdh> yes, it is.
[05:47:50] <XXCoder> nope it isnt
[05:48:50] <archivist> it is!
[05:49:04] <archivist> just
[05:49:51] <jdh> perhpas everyone missed the announcement, but the relative-time-of-day is pinned to whatever time zone I am in.
[05:50:20] <XXCoder> nope everyonje should live on my time zone times. ;)
[05:51:01] <archivist> my timezone is the accurate one being near the meridian!
[05:51:27] <XXCoder> my timezone is where I live ay and its only one that matters because of it!
[05:55:49] <archivist> and a pair of retired GMT clocks
http://www.collection.archivist.info/searchv13.php?searchstr=greenwich
[05:56:23] <XXCoder> interesting
[05:57:36] <archivist> those used a nice double oven crystal clock as the reference
[05:58:44] <XXCoder> double oven
[05:58:48] <XXCoder> oven inside oven? heh
[05:59:41] <archivist> yes and the insulation between is a vacuum flask
[06:00:12] <XXCoder> odd how do it work?
[06:00:19] <XXCoder> I guess it makes temperate very steady
[06:01:01] <archivist> exceedingly, so the drift rate is a few parts in 10^-11
[06:01:26] <XXCoder> wow
[06:02:26] <jthornton> archivist: have you seen any clocks with two minute hands?
[06:02:49] <archivist> looks like the one at the science museum has the later HP caesium clock
[06:03:44] <archivist> jthornton, there are some with extra hands but usually they are alarm clocks
[06:04:19] <jthornton> I was just reading about some clocks that had an extra minute hand one for GMT and one for local time
[06:04:46] <jthornton> https://en.wikipedia.org/wiki/Time_zone
[06:04:57] <archivist> I never came across one
[06:07:15] <jdh> how many TZ have different minutes than GMT?
[06:08:18] <XXCoder> theres actually 26 time zones
[06:08:24] <archivist> not many
[06:32:14] <_methods> wait till trump is prez he's gonna move the meridian to trump plaza
[06:33:44] <archivist> he is carefully making himself unelectable
[06:33:55] <_methods> i hope so
[06:35:43] <archivist> time the world invented some real democracy
[06:36:22] <_methods> he made rudy giuliani wear a hat that said "make mexico great again, also"
[06:36:23] <_methods> hahahah
[06:36:42] <_methods> i need to start selling hats that say
[06:36:51] <_methods> make guatemala great again while you're at it
[06:37:10] <_methods> make canada great again when you get around to it
[06:37:42] <archivist> when I was over there for a holiday I spotted a sign with "Vote mental retardation"
[06:37:52] <_methods> hahah
[06:37:56] <_methods> that about sums up his campaign
[06:38:05] <archivist> must scan that image
[07:09:02] <archivist> _methods,
http://www.collection.archivist.info/archive/DJC/pictures/America_85/pg0002.jpg
[07:10:12] <_methods> hahahah
[07:10:52] <_methods> i need to slap some of those signs up in my area
[07:11:33] <archivist> does trump mean fart in merican engrish too
[07:13:08] <_methods> i have no idea
[07:13:16] <_methods> but sounds like it should
[07:13:32] <archivist> http://english.stackexchange.com/questions/264355/in-what-english-speaking-communities-does-trump-refer-to-the-breaking-of-wind
[07:15:20] <_methods> hahah an especially noisy fart
[07:15:47] <archivist> he fits that definition very well
[07:16:40] <_methods> that's what i was thinking
[07:33:20] <MacGalempsy> Good 1300UTM
[07:36:22] <_methods> lol
[09:25:24] <MacGalempsy> According to tracking info, some metric ER20 collets should be coming in today. Time to make some progress...
[10:18:13] <gregcnc> do you Schlieren?
https://www.youtube.com/watch?v=NmS6h_fkPgk
[10:21:37] <skunkworks> you just need a huge telescope mirror...
[10:21:43] <skunkworks> ;)
[10:22:01] <gregcnc> yeah something I wanted to try
[10:58:19] <archivist> bit of a tool chest
http://swingleydev.com/ot/get/259977/single/
[11:24:43] <MacGalempsy> archivist: I am having issues with the x and y feeds being spuratic, not an even feed. When I manuall move the machine it is smooth. Any suggestions?
[11:25:34] <archivist> sounds like a noise problem
[11:26:39] <MacGalempsy> hmm. this is the first part I am having this issue with
[11:27:46] <skunkworks> if your accelleration is low - it has to slow down to change direction..
[11:28:02] <skunkworks> you could also again try playing with G64...
[11:28:33] <archivist> we dunno what the real problem is
[11:28:34] <MacGalempsy> first I tried a g61
[11:28:45] <MacGalempsy> and that is when it started
[11:28:57] <MacGalempsy> then I tried a g64 p0.005 and that did it itoo
[11:29:19] <MacGalempsy> so then I opened it up to p0.015 and that still did it. then finally, turned it off and it is still doing it
[11:29:36] <archivist> this is servo?
[11:29:39] <MacGalempsy> yes
[11:29:50] <archivist> tuned right?
[11:30:01] <MacGalempsy> i wish... that has been a battle...
[11:30:31] <MacGalempsy> guess I need to work on that a little more...
[11:31:18] <archivist> or show a vid with the problem so we can see/hear it (and halscope maybe)
[11:31:35] <skunkworks> inch or metric?
[11:38:16] * Loetmichel and his co-workers are already betting on how long the "fingerprint-attendance recorder" will hang right next to the entrance to the company (mounted yesterday)... my bet is "until october first, when the bosses wife has to payout about 10-20 hours overtime per employee... ;)
[11:38:58] <MacGalempsy> inch
[11:39:53] <SpeedEvil> Loetmichel: :)
[11:40:25] <skunkworks> MacGalempsy, what is your acceleration?
[11:41:11] <MacGalempsy> max 4
[11:41:22] <skunkworks> that is your problem
[11:41:43] <MacGalempsy> up or down?
[11:42:39] <archivist> sufficient
[11:43:01] <skunkworks> heh - the higher the better to keep the feed up for a given shape
[11:43:27] <MacGalempsy> I am going to work on the PID tune a little and see what happens. I felt they were a little over tuned
[11:43:45] <skunkworks> what machine is this?
[11:45:16] <skunkworks> this is (if I recall correctly) was 20in/s^2
[11:45:19] <skunkworks> https://www.youtube.com/watch?v=81uwBAuR96I
[11:45:38] <skunkworks> (gcode program running flat out)
[11:56:48] <oussama> Hello, i have developped a new interface for linux cnc but when i try to run it i find this problem '' stopping realtime threads unloading hal components" how can i resolve it?
[12:00:04] <Simonious> Well, the problem is still there today :/ Got this box:
https://photos.google.com/photo/AF1QipOdqAAATJDHRZfQxYuc23nTka0h7yU_s-IRYkKn had a hand built BOB on it and it was working, but it was only half a BOB and I wanted the rest so rather than build I bought
[12:00:12] <Simonious> http://www.collection.archivist.info/archive/mirror/cnc/bob/$_57.JPG
[12:00:25] <Simonious> got step and direction AT the gecko 320s
[12:01:08] <archivist> heh we were just talking about gecko's and driving in another channel
[12:01:37] <Simonious> but no motor movement
[12:01:46] <Simonious> put the old BOB on there.. no motor movement
[12:01:49] <Simonious> so.. I dicked something up
[12:01:51] <archivist> now make sure you have the charge pump working
[12:01:51] <Simonious> still don't know what
[12:02:07] <Simonious> archivist: I've got 65V on the motor power pins on the geckos
[12:02:27] <archivist> not bothered about the voltage yet
[12:02:36] <Simonious> okay, what is the charge pump?
[12:03:04] <archivist> many geckos need a signal on the charge pump to enable the drive, a safety feature
[12:03:31] <Simonious> http://www.geckodrive.com/gecko/images/cms_files/G320%20REV-7%20Manual%20Formatted.pdf <- shouldn't the err/res light be lit if they weren't enabled?
[12:04:15] <CaptHindsight> anyone have a good source for CO2 lasers in the USA?
[12:04:24] <CaptHindsight> 30W
[12:04:47] <archivist> Simonious, I have no geckos see
http://wiki.linuxcnc.org/cgi-bin/wiki.pl?About_Charge_Pumps
[12:05:49] <archivist> I cannot open that pdf either
[12:21:13] <pink_vampire|2> Simonious: - i'm using the g320x, they work amazing after the right tuning
[12:21:44] <pink_vampire|2> if you need help with them ping my nick
[12:24:45] <FloppyDisk525> I'm not in Des Plaines, but this could be nice:
https://www.proxibid.com/aspr/Hardinge-Model-CHNCII-Super-Precision-CNC-Lathe-S-N-CN-4650-P-with-GE-F/32013999/LotDetail.asp?lid=32013999
[12:27:05] <archivist> but you can collect it and drag it home
[12:33:28] <CaptHindsight> nice sturdy cross slide
[12:33:59] <CaptHindsight> me like, me want
[12:35:34] <plpower> hi
[12:36:12] <plpower> still a full sun here in germany no rain for weks
[12:36:57] <Loetmichel> plpower: yeah. have to fill the 90 liters water bucket on the balcony nearly daily so wife can water the balcony plants...
[12:37:17] <CaptHindsight> sun and 20C here earlier, we get maybe 10 days a year with this weather
[12:37:30] <SpeedEvil> CaptHindsight: I suppose saying ebay is cheating?
[12:37:32] <plpower> river floting along the houseside ;-(
[12:38:18] <Loetmichel> i mean: wife did quite a forest out there... but still... 90 liters a day...
[12:39:14] <_methods> best kickstarter ever!!!
[12:39:16] <_methods> https://www.kickstarter.com/projects/143749029/the-turtle-hat-helping-people-come-out-of-their-sh
[12:39:20] <Loetmichel> http://www.cyrom.org/palbum/main.php?g2_itemId=15835&g2_imageViewsIndex=1 <- by now the whole climbing rack is filled up to the ceiling...
[12:56:01] <plpower> https://www.youtube.com/channel/UCfVAyiqfH6gUq5FwzfoP2YA/live
[12:56:39] <MacGalempsy> ok. I tuned them a little better, lets see how it goes.
[12:57:20] <plpower> MacG geck203
[13:06:42] <MacGalempsy> plpower: using what I got!
[13:07:08] <plpower> as always it is best to have the right stuff
[13:09:44] <MacGalempsy> considering it came from the factory with this stuff, I guess its the right stuff
[13:17:56] <Simonious> found the problems
[13:18:09] <Simonious> problem #1 'common' on the geckos apparently means logic 5V
[13:18:35] <Simonious> problem #2 in all my fiddling I reversed step and direction pins, so when I did get that part right it still didn't work
[13:18:50] <plpower> stable logic power is always a real issue on the servos
[13:19:30] <archivist> Simonious, all working now?
[13:19:59] <Simonious> archivist: all the axis are working now, I'm on another project at the moment, but hopefully the rest goes well.
[13:21:15] <plpower> im off
[13:31:11] <asdfasd> https://youtu.be/0AKW-K4RyXo?list=PLWstivZ-shduro7G8yL0-hiRN9cSs93KU&t=716
[13:31:16] <asdfasd> what the hell is that ?!?
[13:31:40] <Simonious> archivist: Hmm, I think the axis are all working, my buddy decided to go play with it.
[13:32:04] <Simonious> Fixed the direction on X, but Y is TWO drivers, TWO servos and only one fired. So checking wiring there.
[13:32:18] <Simonious> Have both geckos ganged off of one pin on the BOB
[13:32:28] <archivist> asdfasd, guns are "rifled"
[13:33:11] <Simonious> pfred1 mentioned that the BOB can probably only source 40ma and the 2222s I was using could source 150ma, but then.. the geckos should be very high impedence inputs so... I don't see how running two geckos on one pin could be a problem really.
[13:33:17] <archivist> it is a geared helical path being generated
[13:33:37] <Simonious> I guess I can grab another output if needed for the Y
[13:35:03] <archivist> you would want separate step and dir pins for normal control, cannot imagine connecting two on one pin
[13:35:54] <Simonious> archivist: hard to imagine why that would matter, why do you say that?
[13:36:03] <Simonious> I never want independent control of those..
[13:36:07] <Simonious> that'd would just lead to racking
[13:37:07] <archivist> because you want to square up
[13:37:31] <Simonious> yikes
[13:37:43] <Simonious> I do that manually
[13:37:54] <Simonious> I've got a visual marker on the gantry
[13:38:37] <archivist> people often get linuxcnc to use two switches for that or something similar
[13:38:38] <Simonious> I guess it wouldn't be impossible to do that with homes.. I do have a right and left home position for the gantry, not currently using the right switch
[13:39:03] <archivist> see gantry homing docs
[13:40:44] <archivist> the correct way to parallel on one pin would be to put the optos in series and reduce the series resistor
[13:41:31] <Simonious> oh that sounds interesting
[13:41:43] <Simonious> I was planning to do HOME on one pin (still am) and just do touch offs
[13:41:53] <archivist> would be an internal mod, or possibly buffer the driver on the BOB
[13:43:16] <Simonious> well.. my 1st goal is to get the axis working well
[13:43:22] <Simonious> then.. endstops
[13:43:23] <Simonious> then home
[13:43:25] <Simonious> then touch plate
[13:43:27] <Simonious> then VFD
[13:43:36] <archivist> that bob hast HCT drivers iirc not checked a datasheet for its max current
[13:43:38] <Simonious> so.. that may make the list someday
[13:44:05] <Simonious> archivist: sure, but the geckos aren't pulling any current to speak of
[13:44:36] <Simonious> I'
[13:44:37] <Simonious> m
[13:44:43] <Simonious> not opposed to putting them on seperate pin outs
[13:44:48] <archivist> 10-15ma per opto input
[13:44:54] <Simonious> ooo, that isn't much
[13:46:03] <MacGalempsy> well, after tuning it all up, I realized that the g61 was not changing when I was replacing it with g64 p0.015
[13:47:15] <archivist> Simonious, you should check hct sink current :)
[13:48:19] <Simonious> archivist: what is hct?
[13:49:11] <archivist> I was just looking at a random chip 25ma per output and the vcc pin was 50
[13:50:58] <archivist> ok chips are HC245
[13:54:26] <archivist> so be careful total vcc or ground current is 70 ma, this is shared between outputs
[13:55:34] <Simonious> I couldn't find the input current to the gecko, but.. it's got to be tiny
[13:55:57] <archivist> no it is an opto drive 10ma or more
[13:56:04] <Simonious> My buddy is looking at it now, he removed the servo that was working and tried to drive just the other one
[13:56:07] <Simonious> and.. nothing
[13:56:13] <Simonious> no power to the servo
[13:56:26] <Simonious> I don't think this is a current to the gecko problem
[13:56:46] <archivist> scope, dvm check voltages
[13:56:48] <Simonious> I think tearing the machine down bumped a few problems that were waiting to happen
[14:05:21] <oussama> I have developped a new inteface for linux cnc with python and glade but when i run it i find this problem '' stopping realtime threads unloading hal components " how can i solve it?
[14:05:30] <Simonious> ahh, the fuse popped on Yo
[14:05:41] <Simonious> oussama: I don't think anyone knows
[14:06:19] <oussama> why?
[14:06:26] <cradek> oussama: you'd have to tell us a lot more, and share your work, to get a good answer. it would be best to make your work available on github if you want to collaborate with others!
[14:10:36] <Simonious> pin 5 on the gecko 320 is an err pin.. I'm thinking there is probably a reasonable way to run those together and back to the computer so the computer knows to halt the operation if one of the drivers faults
[14:19:11] <oussama> cradek: when i add the python code for the buttons i find this problem
[14:24:27] <cradek> sounds like your gui is just crashing and exiting
[14:24:57] <cradek> you'll have to debug it, or share your changes and ask for help finding what is wrong
[14:27:36] <MacGalempsy> finally back to cutting
[14:28:20] <MacGalempsy> lol, while tuning I removed the work piece, but put it in backwards... good catch!
[14:46:39] <MacGalempsy> these metric er20 collets from china, lack the lables half of them...
[14:47:31] <archivist> tapers dont match that well on my ER collets
[14:48:19] <MacGalempsy> I do like that the ones that are labled have a range. the imperial ones I have just state a single fraction
[14:50:14] <archivist> the whole idea is some stretch/range so one only needs metric or imperial, not both :)
[14:51:19] <MacGalempsy> i didnt even think about that before ordiering the metric. luckily they were not that much $$$
[14:51:41] <archivist> morse and R8 are a different animal, there you need exact size for best grip
[14:51:56] <MacGalempsy> the drill press I have uses morse #3
[14:52:35] <MacGalempsy> just need to find a good deal on a rotary phase converter. all the 5hp units are about $375
[14:52:42] <MacGalempsy> and the transformer is about 100
[14:52:43] <archivist> I use morse collets in the mill and lathes
[14:53:38] <MacGalempsy> the runout on the spindle was 2 ten thous
[14:57:23] <Simonious> got the axis working right, home is coming along, got my buddy working on home right now, either we're hitting the endstop first or the home switch has a bad wire
[15:02:33] <MacGalempsy> Simonious: are you using HAL meter to check the home signal?
[15:03:53] <Simonious> MacGalempsy: not yet, just hitting home. It's touching off Z beautifully, but X is triggering a joint error, so my assumption has been that we're hitting the limit switch before the home switch
[15:06:56] <miss0r> Finaly something that works on this x-carve
[15:07:03] <Simonious> :)
[15:08:05] <miss0r> I "readjusted" the old spindle mount, all is looking great, then I notice I didn't take into acount the reach - I couldn't reach the milling bed. So I made a new one. now it seems to be right :)
[15:09:01] <miss0r> And the beauty of making new parts for something like x-carve, its just fine to be within 0.01mm ish
[15:09:34] <miss0r> even 0.05 will do :) it takes half the time to build new parts with such a low standard :D
[15:16:32] <ctjctj> miss0r, boy do I get that. The CNC has a 40,000steps per inch and I'm happy if I can get 0.001 repeatability. On the other hand I shoot for 0.0001 for much of my manual work. (Unless I'm in a hurry. If I can do a tenth consistently I can choose to be within a thousand when I don't need to waste so much time.
[15:17:00] <ctjctj> My CNC is used to create patterns for castings anyway. As long as the pull is smooth good to 0.005 is more than good enough.
[15:17:24] <miss0r> you are speaking inches, I presume ? :)
[15:17:30] <MacGalempsy> Simonious: you might try manually triggering the limit switch to see if the signal is setup correctly.
[15:17:36] <MacGalempsy> sometimes they are reversed
[15:19:03] <ctjctj> miss0r, is there any other real units? *grin* Yes.
[15:20:04] <ctjctj> Is it possible to use an "or2" to combine two inputs, one NC and the other NO for use as probe-in?
[15:20:34] <miss0r> hehe. i've always found inches to be quite confusing
[15:20:58] <MacGalempsy> miss0r: its all about knowing both!
[15:21:13] <miss0r> ctjctj: you 'can' use both, yes
[15:21:20] <ctjctj> miss0r, inches are not confusing. inches, feet, miles, gals, cups, oz, and lbs is what makes it confusing.
[15:21:34] <miss0r> MacGalempsy I know converting, anyway ;)
[15:21:51] <Magnifikus> i had to disassemble my old isel mill today, and was somewhat shocked by the ballscrew nut
[15:21:53] <ctjctj> miss0r, It is very interesting to me because I switch to SI units without thinking in certain contexts.
[15:21:55] <miss0r> not realy. What confuses me is people using 3/8 1/16 ... ect
[15:21:57] <Magnifikus> this little piss thing oO
[15:23:24] <miss0r> ctjctj: to add a comment to your earlier comment :) -> Usualy I build stuff to be within 0.001 (MM). or even 0.0005 (MM). This is realy a nice breakoff :)
[15:23:26] <ctjctj> miss0r, the only acceptable is 2015-09-01 19:55
[15:24:07] <miss0r> that will do, I would pretty much reverse it. but as long as its not MM/DD/YYY
[15:24:18] <ctjctj> I use year-month-day and 24 hour format everywhere, even though I'm an American.
[15:24:37] <ctjctj> I hate trying to figure out if it is the 1st day of the 9th month or the 9th day of the 1st month.
[15:25:07] <ctjctj> The other cheat is that if you use yyyy-mm-dd then you can use a simple sort.
[15:25:08] <miss0r> Whomever thought that up should be dug up and hung :]
[15:25:29] <ctjctj> It was the French....
[15:26:17] <miss0r> anything that is "not quite alright" can somehow be traced back to the french...
[15:26:39] * ctjctj points miss0r at SI and ISO
[15:26:48] <ctjctj> Yep, the French had their fingers in that.
[15:27:08] <miss0r> I didn't say that everything that comes out of france is bad, just that all that is somehow bad can be traced there ;)
[15:27:33] <MacGalempsy> miss0r: do your encoders go that small?
[15:28:07] <miss0r> MacGalempsy no :) they do 0.001, the 0.0005 is when I grind hardened steel
[15:28:13] <miss0r> manually
[15:28:15] <MacGalempsy> ah ok
[15:28:30] <MacGalempsy> most calipers dont even go that small
[15:28:45] <miss0r> nope. and the ones that do cost a fortune, trust me, I know
[15:29:35] <miss0r> which is ridiculous for me atleast. I have a mic that does 0.0005. but in my somewhat changing shop temperature it is useless
[15:30:53] <miss0r> well, in the winter time I control the temperature quite precisely - but in the summer time I dont, 'cause air conditioning is too expensive to keep running all the time
[15:32:46] <ctjctj> miss0r, very good point.
[15:33:13] <miss0r> I regret buying that damn thing. It set me back $500
[15:33:30] <ctjctj> The Calipers?
[15:33:48] <miss0r> the mic... well the screw for the mic. its a Mitutoyo 153-301.
[15:34:18] <ctjctj> miss0r, 0.0005mm?
[15:34:29] <miss0r> yeah
[15:35:01] * ctjctj just shakes his head. "silly SI people. Just assume everybody is their weird units"
[15:35:18] <miss0r> hehe
[15:35:35] <miss0r> in your terms its 1.96850394 × 10e-5
[15:35:47] <ctjctj> I'm sitting here thinking "But my Starretts all do 0.0001, what's the big deal with 0.0005?"
[15:36:56] <ctjctj> .0000196850394. Yeah, about 20 millionths. Or about 5 times more accurate than my mics.
[15:37:02] <miss0r> I get that. Sometimes when someone in here writes he managed to do 0.001 precision on an ebay cnc router, I find my self thinking: How the hell is that possible? or are you drunk.
[15:37:27] <miss0r> because I assume everyone is metric ;)
[15:38:20] <miss0r> I had an ebay cnc once. That is actualy what got me started with CNC stuff.. I cannot believe they even pass that off as a product.
[15:38:44] <miss0r> at best its a flimsy paper weight
[15:39:02] <ctjctj> I remember just getting started with CNC and machining. I was talking to my mentor and said "And it is accurate to a 4 thousandths. He was hearing "0.004" and I was meaning "0.00025"
[15:40:07] <miss0r> hehe. Sadly my mentor was the internet.
[15:40:17] <ctjctj> Today I know I as talking from ignorance. If the machine was perfectly tuned and ridged as heck it would be able to do that. And the chances of that being true is somewhere between nil and zero.
[15:41:10] <miss0r> I have an old CNC machine, I manage to get some good results with, because I know it intimately
[15:41:29] <miss0r> Anyone else would have a hard time, because it is worn
[15:42:18] <ctjctj> Right now I'm having finishing problems. I KNOW it is the lead screw. The lead screw is 1/4in all thread. I'm pretty sure that it is wiping and causing the spindle to jerk back and forth... I'm going to try reducing the speed for finishing cuts but I need to make sure I don't dwell and burn the cutters.
[15:43:07] <miss0r> What machine are you working on?
[15:43:20] <SIM_CNC> anyone know off hand how to adjust the touch off value when homing? Mine isn't touching off far enough
[15:43:53] <ctjctj> miss0r, I built a JGRO.
[15:44:30] <miss0r> Doesn't mean alot to me :S Do you have a picture?
[15:44:47] <miss0r> SIM_CNC: can you be more specific? What are you trying to do?
[15:45:15] <SIM_CNC> miss0r: all HOME switches are on one PIN, so any home switch can open, when homing it HAS to touch off (release the switch) or home will fail
[15:45:22] <SIM_CNC> it isn't touching off far enough of one switch
[15:45:22] <miss0r> cjtcjt: All google images show are basically plywood machines
[15:45:31] <ctjctj> SIM_CNC, it is in your stepconf if you use that. and it is in your .ini file "HOME_OFFSET" per AXIS
[15:46:01] <SIM_CNC> ctjctj: ahh, thanks
[15:46:55] <ctjctj> SIM_CNC, I don't know ini that well. But there is a place for you to look.
[15:47:01] <ctjctj> miss0r,
http://www.myheap.com/images/stories/Downloads/cnc_router_jgro.pdf
[15:47:05] <SIM_CNC> found it already
[15:47:22] <SIM_CNC> next question: two of the axis are homing in the wrong direction for my preference, happen to know how to toggle that?
[15:47:29] <miss0r> Ahh, actualy a quite simular design to the ebay special :)
[15:47:39] <miss0r> hopefully build better ;)
[15:47:47] <ctjctj> SIM_CNC, in stepconf you select invert for your step direction.
[15:47:57] <ctjctj> SIM_CNC, and you can change something in your hal file.
[15:48:04] <SIM_CNC> ctjctj: no, no.. step dir is correct
[15:48:31] <miss0r> so you just need to tell it, the homing switches are in the other direction
[15:48:33] <ctjctj> SIM_CNC I'm guessing the HOME_OFFSET value.
[15:49:00] <SIM_CNC> SIM_CNC: I don't think we can use HOME_OFFSET for both touch off distance AND which direction to find the endstop..
[15:49:27] <miss0r> cjtcjt: do you have a picture of your specific build (I do very much enjoy to see what people've build)
[15:50:04] <ctjctj> miss0r, no, it was not built better than the ebay version. It was built with hand tools, a drill press and a table saw. My changes were a bigger Z platform to hold a real spindle/router. I also just finished machining a real spindle holder.
[15:50:10] <ctjctj> miss0r, I'll go take a picture.
[15:50:27] <miss0r> sweet.
[15:51:16] <miss0r> it goes for you and anyone else in here: i'll gladly pitch in for free machining parts for peoples designs(within reason ofc) as long as they pay for the shipping. but you are probally in the states, which makes it ridiculously expensive
[15:51:52] <miss0r> SIM_CNC: also, you should read this:
http://linuxcnc.org/docs/html/config/ini-homing.html
[15:52:06] <SIM_CNC> miss0r: I'm 2/3 through it now :)
[15:52:17] <miss0r> good :)
[15:53:21] <ctjctj> miss0r, I have a south bend 13"x5' and a bridgeport. I know better and am working on rebuilding parts.
[15:53:34] <SIM_CNC> I didn't spot anything in there for specifying home to be at the other end of the axis
[15:54:15] <miss0r> ctjctj: alright. Sounds like you are getting it then :)
[15:55:09] <miss0r> SIM_CNC I think this guy has a useable guide:
https://forum.linuxcnc.org/forum/32-documents/12146-an-explanation-of-limits-homing-hope-its-clear
[15:55:11] * SpeedEvil just got a gluegun-printer for that purpose.
[15:55:16] <ctjctj> https://goo.gl/photos/jNikEZoL5wPK64b58 yes it is that bad. But it works.
[15:55:17] <SpeedEvil> - helping build better tools
[15:55:57] <ctjctj> miss0r, my original intention was to get it build and then immediately use it to build a more accurate version.
[15:56:14] <SIM_CNC> ahh, to reverse home one must put in a negative number for the HOME_SEARCH_VEL (not tested, just found in a forum)
[15:56:59] <ctjctj> The plans called for tapped 1/4" 20 holes in the MDF. I went for cross drilled holes and cross pin nuts (The barrel things that are used by Ikea)
[15:57:06] <miss0r> i'm not judging. I wish I had started building my own instead of spending something like $1000 on a shitty mill
[15:57:22] <SpeedEvil> yeah.
[15:57:32] <SpeedEvil> At least with your own shitty mill, you've learned stuff
[15:57:39] <miss0r> indeed.
[15:58:39] <SpeedEvil> Though I got weak when I was ordering PLA and ABS and stuff for making a 'proper' 3d printer, when I saw a steel cased 3d printer actually in my 'that's not horrible' price range and delivering tomorrow.
[15:58:50] <ctjctj> miss0r, I did not take it as judging. I'm attempting upgrades slowly. I used joyless(?) couplers and added thrust bearings and such. I am planning to upgrade from 1/4" 20 to 1/2 10 TPI with 2 start acme lead screws.
[15:58:52] <miss0r> I started out isolation milling PCBs. It went 'alright' untill I advanced to double sided boards. I drilled 4 holes for metal pins with the mill, so that relocating would be easy after flipping the board. only it turned out the holes didn't fit after I flipped it. some mindboggling time later, I found that over a square of 100x160mm I lost 3 mm :)
[15:59:28] <ctjctj> miss0r, you lost 3mm in 160?
[15:59:36] <miss0r> cjtcjt: If I were you i'd go buy the cheaper ballscrews
[15:59:45] <miss0r> yeah, thats the shitty ebay machine for'ya
[15:59:56] <ctjctj> miss0r, there is nothing cheap about 5ft of ballscrews.
[15:59:57] <miss0r> because it was VERY off-square
[16:00:21] <miss0r> well, ebay has some affordable ballscrews that are not that bad.
[16:00:28] <miss0r> for a wooden machine anyway
[16:00:54] <miss0r> with acme screws, its hard to eliminate backlash properly
[16:00:58] <XXCoder> miss0r: you sure its scaling correctly?
[16:01:02] <ctjctj> In the pictures you might be able to see some pins sticking up. That's how I squared the dang thing. I had it drill 3 holes on the Y axis and then 4 on the X and drove 1/4 wood dowels into them.
[16:01:07] <LeelooMinai> Or Aliexpress - I got my ballscrews from there (and rails, etc.)
[16:01:32] <ctjctj> miss0r, there are some reasonable anti-backlash nuts for acme as well.
[16:01:44] <ctjctj> LeelooMinai, *nods* I'm sacred of aliexpress.
[16:01:54] <miss0r> XXCoder: quite. and this is years back. When tearing it down, I found that all the rails (round bars) were just tightened up against the paint with a 6mm screw in an 8 mm hole :)
[16:02:17] <SIM_CNC> ctjctj: aliexpress is often slow, but you generally get what they claim you will get.. if you can figure what that is.
[16:02:18] <XXCoder> bleh heh
[16:02:29] <miss0r> ctjctj: that is true, but when you apply force to them, they will give backlash anyway (in my opinion anyway)
[16:02:32] <SIM_CNC> ctjctj: I bought 10 arduines there for ~1.90 ea
[16:02:36] <SIM_CNC> *arduinos
[16:02:37] <LeelooMinai> Well, I can tell you that I ordered tons of stuff from Aliexpress, and never had a problem. Some things were pretty risky, like my inspection microscope for electronics - but it's great.
[16:02:44] <ctjctj> miss0r, yes.
[16:03:19] <XXCoder> unless its car lights
[16:03:24] <XXCoder> they always get that wrong
[16:03:46] <miss0r> then just start ordering the 'oposite' then :)
[16:03:54] <XXCoder> to be fair most was fine, its just my van's brake/flasher combo leds that they always screw up on building
[16:04:11] <XXCoder> there is so ways it could go wrong and they basically found all of em
[16:04:50] <miss0r> ebay has a tendency to screw you over for sure. :) I ordered a digital/electric edgefinder. It was 0.3mm out-of-round :)
[16:04:59] <LeelooMinai> I ordered a lot of milling bits from them, etc. - they have good prices
[16:05:02] <miss0r> and it said 0.01mm acuracy
[16:05:15] <ctjctj> miss0r, did it have the four screws to adjust the run out?
[16:05:21] <miss0r> nope
[16:05:49] <ctjctj> miss0r, I'd double check if you have not sent it back.
[16:05:50] <miss0r> and apparently the seller knew of the problem, as I got my money returned 45 mins after sending a complaint. He didn't even want the unit returned
[16:06:26] <miss0r> holding it in my hand now - it has nothing.
[16:06:29] <LeelooMinai> But did it find the edge? Yes... so what's the problem:p
[16:06:40] <miss0r> ^^
[16:07:04] <ctjctj> miss0r, hmmm. I'm about to buy such a probe, but it works like a four jaw chuck to dial it in as close as you want for your spindle.
[16:07:23] <ctjctj> XXCoder, AliExpress keeps trying to force me to log in...
[16:07:40] <XXCoder> weird
[16:10:06] <miss0r> The one I bought looks like this:
http://i.ebayimg.com/16/!B(2sQo!Bmk~$(KGrHgoH-CYEjlLl9odTBKech9rlrw~~_1.JPG
[16:10:11] <miss0r> only the one I got has a 16mm shank
[16:10:35] <XXCoder> lol that breaks irc client link, had to copy paste
[16:11:09] <pink_vampire> it's super simple to make yourself a probe
[16:11:26] <LeelooMinai> Right, use a nail
[16:11:29] <miss0r> it even came with a little yellow slip of paper saying "tested before shipping to ensure 100% acuracy" hehe
[16:11:37] <ctjctj> miss0r, oh.... This is what I was thinking about:
http://www.ebay.com/itm/like/142053837865
[16:11:45] <miss0r> apparently someone used it to hammer in nails with it in transit then
[16:11:54] <pink_vampire> too expensive
[16:12:15] <ctjctj> I'm thinking of attempting to making one.
[16:12:27] <SIM_CNC> I seem to remember that at gcode generation time one must specify if the work is from absolute machine home or from a relative work home, right?
[16:12:29] <ctjctj> pink_vampire, do you have something you can recommend?
[16:12:46] <SIM_CNC> got XYZ homing working nicely now
[16:12:50] <miss0r> ctjctj: it looks good.
[16:12:57] <pink_vampire> i have the one that i build for almost free
[16:12:58] <miss0r> I use a haimer 3d taster for everything now'a'days
[16:13:02] * SIM_CNC is still confused about machine home / work home
[16:13:12] <ctjctj> SIM_CNC, in most cases you want to home, and then touch off to find a zero on your work piece (stock)
[16:13:30] <pink_vampire> just 1/8" brass rod and some plastic sheets
[16:13:32] <SIM_CNC> ctjctj: ah! that sounds pretty reasonable
[16:13:53] <miss0r> sim_CNC: the machine home is the "extemities of the work area". i.e. set by limit switches. The work home, is where you set your zero point on the workpeice. so the machine works from there
[16:14:13] <SIM_CNC> miss0r: using 'touch off' as ctjctj said?
[16:14:24] <SIM_CNC> to set work zero?
[16:14:27] <miss0r> indeed
[16:14:38] <SIM_CNC> great!
[16:14:39] <LeelooMinai> Well, you need correlate that work home with the actual piece you have on the table
[16:14:50] <SIM_CNC> uh oh.. complications..
[16:14:54] <LeelooMinai> So that's the touch off part
[16:15:00] <ctjctj> SIM_CNC, g-code has the concept of alternative coordinate systems. There are 9 of them. G53 is machine coordinates. G54..G??? are the nine of them.
[16:15:01] <SIM_CNC> ahh, right
[16:15:01] <pink_vampire> http://i.imgur.com/ziixI2O.png
[16:15:18] <pink_vampire> this is how i made my probe
[16:15:30] <LeelooMinai> Seems like that expired Rainshaw patent type
[16:15:35] <miss0r> I think I already druled over your design sometime in the past :)
[16:15:47] <XXCoder> I think I;ll just 3d print one up lol
[16:16:02] <SIM_CNC> ctjctj: and do I have to know my machine coordinate system at gcode generation time?
[16:16:25] <ctjctj> pink_vampire, about what I was planing on building. I was concerned about making sure that distance between the bottom plate and the top of the balls was exactly the same.
[16:17:17] <pink_vampire> it's not effect the way it's work
[16:17:38] <ctjctj> SIM_CNC, in your CAM (or when hand coding) you set your units. Then when setting up you select the plane (almost never changes), and then the coordenate system you plan to use. using the Axis touch off sets the coordinate system.
[16:17:56] <ctjctj> pink_vampire, I don't understand.
[16:17:59] <pink_vampire> even if the kinematic will be mount in angle it will work
[16:18:35] <ctjctj> pink_vampire, but if the spindle rotates at all it will cause run out that I can't correct with a centering adjustment.
[16:18:41] <pink_vampire> no
[16:19:04] <pink_vampire> all you need is good round shank
[16:19:29] <ctjctj> SIM_CNC, say you want to cut a line down the middle of a piece of stock 2in by 4in
[16:19:35] <ctjctj> pink_vampire, I'll take your word for it.
[16:19:42] <miss0r> SIM_CNC You have the hang of it now?
[16:20:16] <miss0r> SIM_CNC I want to thank you - it is not often people ask questions in here I have a chance of answering :)
[16:20:17] <ctjctj> SIM_CNC, so you want to go from X0 Y1 to X4,Y1. (Ignoring all sorts of cutter offset stuff)
[16:20:42] <LeelooMinai> ctjctj:
https://www.google.ca/patents/US5146691?dq=5146691&hl=en&sa=X&ved=0ahUKEwjR98ywhu_OAhXDbBoKHR0tBqoQ6AEIHDAA
[16:21:44] <LeelooMinai> Expired, so anyone can copy it
[16:21:55] <ctjctj> SIM_CNC, so a g-code like G0 X0 Y1 and then G1 X4 Y1 F10 will cut a line. If you are in machine coordinates this would be at somewhere. BUT if you touch off to the two sides of that stock you'll end up with the G54 coordinate system at one corner.
[16:21:56] <pink_vampire> ctjctj:
https://discord.gg/ANhbeZQ - join for sec i will explain to you
[16:21:57] <SIM_CNC> so... the touch off button only sets ONE machine coordinate system, right?
[16:22:01] <ctjctj> LeelooMinai, yes, I've read it.
[16:22:40] <SIM_CNC> so if/when I get to doing multiples I'll need to create additional buttons or just hand enter touch offs for the other machine homes
[16:22:45] <miss0r> Be sure to know the difference of G90/G91 also ;)
[16:22:55] <SIM_CNC> I don't
[16:23:13] <miss0r> absolute/incremental values.
[16:23:16] <ctjctj> pink_vampire, Hold on, I have to get a windows box for that.
[16:23:39] <pink_vampire> no
[16:23:44] <pink_vampire> any os
[16:23:51] <pink_vampire> linux, windows
[16:23:55] <pink_vampire> mac
[16:24:34] <ctjctj> Ok. Good to hear.
[16:25:43] <miss0r> damnit. i've done it again. stayed up way too late doing nothing but chat with you guys. Have a good one
[16:30:22] <Deejay> gn8
[16:31:25] <ctjctj> SIM_CNC, you set G54 for X,Y and Z and then don't have to do it until you change out your work piece.
[16:31:46] * SIM_CNC nods
[16:32:15] <SIM_CNC> but if I want to do multiples, I could have a honme at G55 too, right?
[16:32:42] <ctjctj> SIM_CNC, lots of things you can do. Start simple.
[16:34:32] <SIM_CNC> I'm interested in seeing someone elses config files for the HB04 pendant, anyone?
[16:34:42] <SIM_CNC> mine works, but I'd like to reference another..
[16:36:34] <SIM_CNC> so nice to have a home button that works! :)
[16:46:15] <Demure_> Question: Does the pncconf, when the spindle & Phase A / Index encoders are set, have closed loop control of the spindle speed?
[16:46:50] <Demure_> I can set the scale to get the commanded speed to be pretty close, but since I have the encoder I don't see why LinuxCNC can't just control the spindle to the commanded speed itself, since it can read the RPM
[16:47:10] <Demure_> I've seen some references to closed loop spindle control, but the version on the wiki is from 2009 and I can't really seem to get into it.
[16:51:00] <Simonious> http://www.cncrouterparts.com/auto-z-touch-plate-p-288.html or a $10 ebay special....?
[16:51:04] <MacGalempsy> there is syncronization
[16:51:52] <Demure_> That I understand, for stuff like threading
[16:52:28] <Demure_> But if I send Gcode to activate the spindle at a specific RPM the only thing actually keeping the commanded RPM close to the actual RPM is the scale I give, rather than encoder feedback
[16:53:32] <Simonious> who here is using a probe to find stock zero?
[16:54:14] <pink_vampire> me
[16:54:29] <Simonious> pink_vampire: oh yeah, I saw your picture, how do you like it?
[16:54:59] <pink_vampire> i like the kinematic
[16:56:21] <gregcnc> you have to do some work in hal file to get the encoder signal talking to the spindle component and feedback working. I did it but this was a while ago and i had no idea what I was doing to begin with
[16:56:57] <Simonious> I guess I don't think I care if I have that capability
[16:57:01] <Simonious> I do want a Z touch off though

[16:57:20] <Simonious> http://www.cncrouterparts.com/auto-z-touch-plate-p-288.html
[16:57:24] <Simonious> something like one of those
[16:58:01] <Demure_> gregcnc: Do you have your old Hal file so I have something to take a look at?
[16:58:30] <HighOctane> How does one know which realtime kernel he should use with linux?
[16:58:36] <MacGalempsy> ebay!
[16:58:42] <pink_vampire> Simonious: I don't like it
[16:58:53] <Simonious> pink_vampire: don't like what?
[16:59:18] <Simonious> your probe? The Z touch plate?
[16:59:25] <MacGalempsy> why dont you just make one like the second ebay one?
[16:59:32] <pink_vampire> because it unsafe on the kinematic switch you are using normally close connection
[16:59:37] <MacGalempsy> you could hand write the code for that one
[16:59:47] <MacGalempsy> or even better, mdi that thing
[16:59:48] <pink_vampire> and on the touch plate it's normally open
[17:00:05] <Simonious> pink_vampire: Ah ha, I wondered about that
[17:00:07] <MacGalempsy> who cares? you can set the HAL code on to a not value
[17:00:14] <Simonious> pink_vampire: I need to do normally closed
[17:00:15] <pink_vampire> and if you don't have a good connection you kill your plate / end mill
[17:00:19] <Simonious> I don't like normally open
[17:00:50] * Simonious ponders
[17:00:53] <pink_vampire> so, just make small platform with kinematic switch on the bottom
[17:01:18] <gregcnc> demure_ I'll have to pull it off the PC it's on maybe tonight
[17:01:30] <Simonious> pink_vampire: I think I can use the touch plate at 5V and then use the tool tip to ground it out
[17:01:33] <ctjctj> I monitor the zprobe down and am ready to kill it. My z-probe touch plate has a good 1/4 to 3/8 of spring loaded travel so there is enough time to notice "stupids"
[17:02:27] <pink_vampire> you basically need to make a probe and place it up side down
[17:02:52] <pink_vampire> or
[17:03:12] <pink_vampire> use the plate in revers
[17:04:05] <pink_vampire> touch it, then move the z up until it disconnect
[17:05:01] <Simonious> pink_vampire: so go normally open.. run down until it closes then slow up until disconnect? That still doesn't sound like 'failsafe' I must have missed something
[17:06:16] <pink_vampire> you lower your z axis down
[17:06:21] <pink_vampire> manually
[17:06:26] <Simonious> ahh..
[17:06:37] <pink_vampire> compress the spring a-bit
[17:07:36] <pink_vampire> then up until it disconnect
[17:07:41] <pink_vampire> Simonious: ^
[17:08:07] <Simonious> I get it now, i was missing the manually down
[17:08:28] <Simonious> in fairness I'm running servos and they will detect crashes and fault the machine
[17:08:38] <Simonious> and 'usually' save the tool
[17:09:04] <pink_vampire> i saw that you had an issue with the g320x
[17:09:18] <pink_vampire> the servo drivers
[17:10:19] <pink_vampire> Simonious:
[17:10:59] <Simonious> that is resolved
[17:11:04] <Simonious> I had two problems
[17:11:14] <Simonious> 'common' on the 320s is supposed to be at logic 5v
[17:11:24] <pink_vampire> correct
[17:11:27] <Simonious> while I had that at ground I fiddled and swapped step and direction
[17:11:33] <pink_vampire> between 5 and 7
[17:11:41] <Simonious> so when I fixed that the drivers didn't know what to do with the signals I was sending
[17:11:43] <pink_vampire> you have to add a jumper
[17:11:58] <pink_vampire> and also the original terminals are junk
[17:12:04] <Simonious> i'm not using those
[17:12:11] <Simonious> I've got breakout connectors
[17:12:35] <pink_vampire> do you have a picture?
[17:12:37] <pink_vampire> http://i.imgur.com/dF9JmOw.jpg
[17:12:49] <pink_vampire> this is how I solved it
[17:14:00] <pink_vampire> Simonious:
[17:15:01] <Simonious> I don't have a picture of that part handy, will get one in a bit
[17:15:25] <pink_vampire> Simonious: thanks
[17:19:29] <Simonious> https://goo.gl/photos/2uAffpNSmiNutPMJ6
[17:20:34] <pink_vampire> why do you need the breakout?
[17:21:34] <pink_vampire> Simonious:
[17:23:25] <Simonious> I was planning to do a fixed z touch off plate, but my buddy is trying to talk me into leaving it float so I can put it on top of stock and zero the tool with each tool change
[17:23:51] <pink_vampire> i know
[17:23:53] <Simonious> pink_vampire: *shrugs* just buffering the port
[17:24:32] <pink_vampire> i mean why you need to connect the servo drivers to breakout board??
[17:24:49] <pink_vampire> https://lh3.googleusercontent.com/jFfEZOZbmqQmHiadyMuACg3BADoDRpZijku7TBo8stSly0mqJBpUV9lpZlCq9oM1erHmat-9ScEDp6L5As-shyiGtGVooskwlzGTuzap0BrDxaGtfvYWG1yXhQuQqlf13De4lxB_9wphlm_2fxF9N8YCmfwE76k0g6gUOKfSR1nVHIkp498mGAlex8-FnxWBedUWGWUUlDk7ZiAWfZC4brB4dAUIT7U3cUWU3PpBE4epx0FE-1Zn3Ji_9n05jEl1ATmpGncFnEnqXnJC8V3g612zipq8WXgHWNcnTTbhGYchIhaENbZRsXXH2a0mwxnPCtVnnA3hXoqskCfZ06_tT4W_ATrz0T-Tfu4wPNGkXoYy01
[17:25:15] <Simonious> bad link?
[17:25:27] <Simonious> I don't think I really need to since it's gecko inputs
[17:26:11] <pink_vampire> there is 2 large caps,
[17:27:28] <Simonious> yeah.. I should gut that CandCNC box and get rid of everything but the PS and the drivers and the BOB
[17:28:17] <pink_vampire> bob?
[17:28:23] <pink_vampire> what is it?
[17:28:24] <Simonious> breakout board
[17:28:40] <pink_vampire> like
[17:28:43] <MacGalempsy> big old baby
[17:28:58] <pink_vampire> on the bottom i see the lpt BOB
[17:29:28] <Simonious> eyup
[17:31:51] <pink_vampire> Simonious:
http://i.imgur.com/qdmhCSg.png
[17:32:08] <Simonious> exactly!
[17:32:18] <Simonious> on the right side it has nice connectors
[17:32:30] <Simonious> it's some left over crap from the CandCNC setup
[17:32:55] <pink_vampire> i see what you mean
[17:32:57] <Simonious> I think this box has the ability to fault the drivers if an endstop is hit (well used to)

[17:33:14] <pink_vampire> and din rails
[17:33:38] <pink_vampire> MacGalempsy: what is that????????
[17:33:48] <MacGalempsy> that is my cnc
[17:34:00] <MacGalempsy> would you believe it is the factory wiring?
[17:34:25] <pink_vampire> wow
[17:34:33] <pink_vampire> super meas
[17:35:34] <Simonious> thanks for all the help and ideas, I'm going home o/
[17:35:52] <pink_vampire> I'm at home..
[17:39:53] <MacGalempsy> me too
[17:41:18] <Crom_> well that was nice... brand new LCD crap out of the bag
[17:41:59] <pink_vampire> Crom_: what do you mean?
[17:42:02] <Crom_> MacGalempsy, I'm gonna have to pass on the auction... tires for the car killed me today
[17:42:22] <Crom_> pink_vampire, didn't work....
[17:44:05] <MacGalempsy> dang. what kind you get?
[17:44:57] <MacGalempsy> Crom_: whats up with the LCD?
[17:45:04] <MacGalempsy> drop it or bad something or other?
[17:45:49] <Crom_> 12864.. won't work with a MKS Gen board, which I know works cuz I had another display running on it
[17:45:58] <Crom_> another 12864
[17:46:10] <Crom_> same make same brand
[17:46:16] <MacGalempsy> so you need one?
[17:46:35] <MacGalempsy> I have an extra one from a RAMPS
[17:46:59] <MacGalempsy> a couple more thousand lines of code and my main motor bracket will be roughed out
[17:47:00] <Crom_> I have another.. it's on a reprap I can pull off
[17:47:17] <MacGalempsy> just need to do a few holes
[17:47:22] <MacGalempsy> and it will be ready
[17:50:10] <Crom_> no money for me this payday... :( $548 for tires today...
[17:52:06] <SpeedEvil> :/
[17:55:33] <Crom_> dang it now I can't find the dongle for my mouse
[17:57:59] <SpeedEvil> There is a handy device some mice come with to avoid that.
[17:58:00] <SpeedEvil> :)
[17:59:57] <malcom2073> A cord?
[18:00:45] <SpeedEvil> :)
[18:04:21] <jdh> how 80's
[18:08:10] <Crom_> well time to grab a corded miseker
[18:10:04] <enleth> any non-obvious advice for milling copper?
[18:13:37] <enleth> I need to make a clamp-on heatsink for copper pipe brazing (to prevent the heat from melting another joint up the pipe) and I have a nice chunk of pure copper plate for this
[18:14:53] <SpeedEvil> I suppose the suggestion of 'just wrap a damp sponge round it' would not be met with favour?
[18:19:02] <cradek> enleth: I've heard use milk for coolant. might be a joke. copper is just terrible to mill.
[18:19:19] <SpeedEvil> Especially with 'conventionally' ground tooling
[18:20:27] <cradek> my advice: throw it away and make a brass heatsink
[18:21:01] <cradek> or yeah, use water!
[18:22:13] <SpeedEvil> a very, very modest water spray also works
[18:28:49] <enleth> cradek: good to know, thanks
[18:30:07] <JT-Shop> wet rag is what plumbers use
[18:30:21] <JT-Shop> of course the rag gets very hot
[18:30:21] <enleth> oh well, wet rag it is I guess
[18:31:14] <enleth> I guess I'll ask someone to re-apply water to it as needed when I do the brazing
[18:31:38] <JT-Shop> brazing should only take a few seconds
[18:31:43] <Valen> chuck it in a bucket of water?
[18:33:36] <enleth> JT-Shop: I'm joining somewhat dissimilar pipe diameters with an adapter sleeve, so there's going to be a bit more mass in the joint than just the pipes
[18:34:00] <JT-Shop> join the big end first
[18:34:06] <enleth> tl;dr repairing an HVAC unit that had a collapsed piping section
[18:34:15] <JT-Shop> ah
[18:34:45] <enleth> the chinese used non-standard pipe diameters, so the HVAC guys couldn't jury rig an adapter without soldering
[18:34:46] <JT-Shop> repair work is always a challenge
[18:35:32] <enleth> so I have to turn some adapters and solder them in to convert the piping to standard 1/4" and 1/2"
[18:35:55] <JT-Shop> watermelon run
[18:36:36] <enleth> it's 9/32" and 3/8" now
[18:37:16] <enleth> the flaring tool couldn't handle the former and they just didn't have fittings for the latter
[18:38:25] <SpeedEvil> Spinning copper is _really_ easy
[18:38:39] <SpeedEvil> to make a fitting
[18:39:52] <enleth> SpeedEvil: maybe, but they don't do it, it's up to me to repair the unit's internal piping and call them to come back to pressure test it and top up R410
[18:40:37] <SpeedEvil> I mean spinning on the lathe instead of turning an adaptor
[19:18:17] <renesis> xxcoder: thats not that bad if they can hold that
[19:18:41] <renesis> damn, talking to scroll from days ago
[20:08:06] <MacGalempsy> witnit: you around?
[20:24:45] <Frank_18> any good place to get couplerS?
[20:25:29] <jdh> mcmaster is easy
[20:40:55] <MacGalempsy> had to run a cleanup operation
[21:02:29] <pfred1> translating this Chinese manual I have entered the sixth dimension
[21:03:37] <pfred1> Q: How to determine the definition of the stepper motor four lines? A: The motor of any two lines
[21:03:40] <pfred1> Together, then hand-tighten the rotor resistance, then these two lines are in the same phase, which can be accessed in the drive
[21:03:43] <pfred1> Actuator A +, A-; the other two lines are still short resistance, it will be two lines connected to B + and B-
[21:03:51] <pfred1> it is all so clear ot me now!
[21:08:05] <jdh> how to tell, if you don't have an ohmmeter
[21:08:49] <pfred1> I used the battery method to phase a mystery motor over here
[21:54:08] <Crom> yeah battery and a light or led + resistor
[21:55:12] <pfred1> I just touch the leads to the battery and feel wich way it turns
[21:55:30] <Crom> pfred1, the other way is tie to lines together, turn the motor if there is reluctance that's one phase.. if none try another wire.. you one have 3 tries to do
[21:56:00] <pfred1> that finds the coils but won't tell yo utheir phase
[21:56:22] <pfred1> phase is +, or -
[21:56:55] <pfred1> swap leads and the motor will jump CW or CCW
[21:57:06] <Crom> I just hook up up the coils, it it turns wrong way I flip a set
[21:57:13] <pfred1> you can do that too
[21:57:48] <pfred1> bu you still might end up with the whole motor spinning backwards
[21:58:50] <Crom> will it affect torque?
[21:58:54] <pfred1> no
[21:59:07] <pfred1> but your dir is inverted
[21:59:42] <pfred1> CW spins CCW and vise versa
[21:59:58] <Crom> flipping a coil pair fixes that
[22:00:02] <pfred1> yes
[22:00:10] <Crom> moe a- to a+ AND A+ TO A1
[22:00:59] <pfred1> but every time you swap leads on a drive you're risking blowing the drive up
[22:01:17] <pfred1> so i try to minimize it
[22:02:03] <pfred1> I got my first "TB6600" drive today it ain't a TB6600
[22:02:28] <Crom> by having a coil and b coil both backwards?
[22:02:44] <Crom> what was it?
[22:03:05] <pfred1> if you swap leads with the drive powered down you're OK but accidents happen
[22:03:33] <pfred1> I don't know what it is the chip is under a heatsink but I can see already it is not the right package
[22:03:51] <pfred1> I'm going to try it before i take it apart
[22:03:53] <Crom> I have to unplug it to get to the connectors anyway
[22:04:11] <pfred1> but it looks like crap so far
[22:04:55] <pfred1> it is some QFP chip
[22:05:06] <pfred1> like surface mount
[22:05:37] <pfred1> far as i know a TB6600 is a ZIP package
[22:06:17] <pfred1> but I'll run it and see what it's like
[22:06:42] <Crom> shoot.. I had a heat sink off and I never looked at the chip
[22:06:53] <pfred1> I got a NEMA 34 motor here that'll take 4 amps and then some
[22:07:55] <Crom> no compound on heat sink though
[22:08:09] <MacGalempsy> jeez this is taking longer than anticipated!

[22:08:38] <pfred1> that's what it is supposed to look like
[22:09:01] <pfred1> thing on this board is maybe a quarter that size no through hole leads either
[22:09:23] <pfred1> I got mao ze donged on this deal
[22:11:23] <Crom> looks similar to my chip... the Z legs got bend to be 90 degrees to body and soldered into through holes, the other legs and soldered to the top of the board ala smd
[22:12:28] <pfred1> I bought this drive to study it so I am chalking it up to a learning experience
[22:12:35] <Crom> my chip doesn't have those 2 slots
[22:13:31] <MacGalempsy> one time i bought a "NEW" phone from China and it was a refurbished piece of crap with dust under the lens...
[22:14:12] <MacGalempsy> ebay rule number 1 hold off on feedback until you get what you want!
[22:14:24] <pfred1> I got this off aliexpress
[22:14:55] <Crom> MacGalempsy, running your job for the first time or is it doing the CAM
[22:16:07] <pfred1> wholly! US $4.70 / piece Shipping: US $40.17 to United States
[22:16:20] <pfred1> what's the guy gonna do personally walk it over?
[22:17:52] <Crom> he's wrapping it in virgin never worn silk bubble wrap, with gold leaf antistatic bags
[22:18:33] <pfred1> man this chip is so obviously counterfeit
[22:18:52] <pfred1> looks like someone hand painted the markings on it

[22:21:36] <pfred1> least the markings are crisp
[22:22:37] <pfred1> I really didn't want to make drives though which is why I'm evaluating some
[22:22:48] <Crom> wow crashed Chrome twice over 3 days
[22:22:58] <pfred1> FF never crashes
[22:23:27] <Crom> I run web thingies which require Chrome
[22:36:09] <MacGalempsy> After they fired the CEO last year, I am anti FF
[22:36:33] <pfred1> MacGalempsy my FF is so old it was before they fired the guy
[22:36:58] <MacGalempsy> it still have the netscape navigator logo?

[22:38:52] <pfred1> I have Netscape on CD I bought it
[23:10:47] <Crom> sheeshz.. I switched to chrome way way back...
[23:12:05] <Crom> used netscape till mozilla was 1/2way stable
[23:12:34] <Crom> still used a ton of lynx back then
[23:13:18] <Crom> and gopher... who's used gopher in the last 15 years?
[23:13:39] <Crom> probably closer to 20 for me
