[00:38:38] <furrywolf> yay, put together the eu6500is. it runs better than the first one I did.
[00:38:52] <furrywolf> I don't know what's wrong with the first one. :(
[00:39:26] <malcom2073> Nice
[00:39:31] <malcom2073> first one doesn't run good?
[00:40:46] <furrywolf> the first one surges at light loads, and I can't find anything wrong.
[00:40:57] <furrywolf> cleaned carb, no change. adjusted valves, no change. new air filter and spark plug, no change.
[00:42:09] <furrywolf> googling found they are very prone to surging, but no relevant solutions.
[00:42:31] <malcom2073> huh
[00:42:36] <malcom2073> Weird
[00:43:02] <furrywolf> every other time I've had to fix a surging small engine, it was a dirty carb or misadjusted valves.
[00:43:04] <malcom2073> osccilation in the spring tension of the idle circut?
[00:43:11] <furrywolf> it doesn't work that way. :)
[00:43:18] <furrywolf> it's drive-by-wire.
[00:43:28] <furrywolf> (or whatever the similar appropriate term for a generator is)
[00:43:55] <malcom2073> Heh
[00:43:57] <furrywolf> it's a carb, like other small engine carbs, but with two small steppers bolted to it, directly working the throttle and choke.
[00:44:00] <malcom2073> ok, then oscillation in the control software? :P
[00:44:12] <furrywolf> it has no mechanical governor
[00:44:18] <furrywolf> I'm pretty sure it is, indeed, lean.
[00:44:36] <malcom2073> Maybe just wear of the motor messes with the fine tuning of it
[00:45:17] <furrywolf> the throttle position is controlled by the inverter based on demand, while choke and spark are controlled by the engine/generator control unit.
[00:45:46] <furrywolf> to prevent a failure from overrevving the engine, since it has no mechanical governor, the ECU will kill spark if it detects excessive rpms.
[00:46:48] <malcom2073> makes sense
[00:47:16] <malcom2073> Replace the throttle controller with a linuxcnc controlled pid loop
[00:47:33] <furrywolf> I already replaced the inverter with a $560 new inverter. :P
[00:48:50] <malcom2073> Yowch
[00:49:25] <furrywolf> eh, I bought the generators for about $10 each...
[00:49:25] <furrywolf> I'll still make a good profit.
[00:49:30] <furrywolf> I bought a lot of 17 broken honda inverter generators.
[00:49:41] <malcom2073> True
[00:49:41] <malcom2073> Haha
[00:49:46] <malcom2073> Yeah I remember, lucky bastard
[00:49:46] <malcom2073> :P
[00:49:48] <furrywolf> so far I have 7 working
[00:49:48] -!- Komzpa has quit [Quit: Konversation terminated!]
[00:49:51] <malcom2073> Nice
[00:50:01] <furrywolf> I figure I can get $1800ish for the 6500s.
[00:50:06] <malcom2073> Nice
[00:50:15] <furrywolf> which will pay for lots of shiny cnc parts. :)
[00:50:20] <malcom2073> woot woot
[00:50:31] <furrywolf> and if pcw ever makes more 7i76es, I'll have money for him! heh
[00:51:03] <malcom2073> When's the 7i77e coming?
[00:51:36] -!- Loetmichel2 [Loetmichel2!~cylly@p54B10B7A.dip0.t-ipconnect.de] has joined #linuxcnc
[00:52:09] <furrywolf> what I found googling was that they're very, very picky about having all baffles, covers, gaskets, etc in place. I think that, to comply with california's emissions crap, they had to tune the carb so it's just barely on the edge of lean, with all the covers and gaskets perfect. if anything lets a little extra air in, it goes lean.
[00:52:27] <furrywolf> I think they're all fine on the first one, but having an issue there seems the most likely problem...

[00:53:30] <malcom2073> Hmm
[00:53:39] <furrywolf> it definitely ran a little better when I duct-taped some of the vents on the battery door
[00:53:42] <malcom2073> Yeah just something small, like a tiny crack in a gasket or something
[00:53:44] <malcom2073> heh
[00:54:11] <furrywolf> if you pull the battery door off, both generators DIE. I tested it on the one I just put together to see if it did the same thing as the first one.
[00:54:25] <furrywolf> the battery access door is a vital component of their operation, apparantly.
[00:54:49] <malcom2073> Haha
[00:54:50] <malcom2073> nice
[00:54:57] <malcom2073> die intentionally (kill switch) or just happens to?
[00:55:13] <furrywolf> goes so lean it backfires and stalls
[00:55:26] <furrywolf> after surging idle-WOT a few times.
[00:55:47] <malcom2073> wow
[00:57:00] <furrywolf> unfortunately, I only have one battery door, so I have to move it between them when testing. heh.
[00:58:26] <furrywolf> hrmm, the first one is missing the spark plug cover. it's internal, and I think on the other side of the baffles from the intake air, but...
[00:59:12] <furrywolf> I also have an EM7000is, but I don't know if it's worth fixing. it has >9k hours, a bad inverter, and multiple other problems.
[00:59:32] <malcom2073> lol
[00:59:56] <malcom2073> I've been eyeing up some surplus military generators
[01:00:02] <furrywolf> it randomly declares low oil even if the oil level is good, and it's not acting like a bad switch.
[01:00:08] <furrywolf> more like electrical issues.
[01:00:10] <malcom2073> hmmm odd
[01:00:30] <furrywolf> I haven't heard it run yet due to this.
[01:01:00] <malcom2073> ah yeah they shut off with the low oil light
[01:01:01] <malcom2073> I remember that
[01:01:36] <furrywolf> well, on this one, it says OIL in flashing letters on the LCD display.
[01:01:56] <malcom2073> Fancy
[01:03:17] <furrywolf> the oil switch goes straight to the generator/engine control unit, which also works the LCD. :)
[01:04:18] <malcom2073> Heh
[01:05:43] <furrywolf> LOL. apparantly the little clips that hold the air box together are the same ones that hold the hvac unit on a honda civic together.
[01:06:34] <furrywolf> https://www.google.com/search?biw=1024&bih=654&tbm=isch&sa=1&q=%2290659-692-000%22&oq=%2290659-692-000%22&gs_l=img.3...34502.36387.0.36586.2.2.0.0.0.0.317.317.3-1.1.0....0...1..64.img..2.0.0.ZhNc3i7Jj-c#imgrc=_
[01:07:13] <malcom2073> haha
[01:07:36] <furrywolf> I need four of them, and they're $5 each. I was searching to see if I could find them cheaper, and the same part number, and picture, is used for the honda hvac units...
[01:07:44] <furrywolf> which means I can get them from the wrecker for $0!
[01:08:24] <furrywolf> because there is NO fucking way I'm spending $5/each for a tiny bit of bent spring steel.
[01:09:45] <furrywolf> that pricing falls under "offensive".
[01:10:04] <malcom2073> Haha
[01:10:07] <malcom2073> That's stupid
[01:10:15] <malcom2073> But kinda expected
[01:11:11] <furrywolf> I'll make them off bits of broken fishtape before I buy them at that price. heh.
[01:14:05] <malcom2073> Like you said, wreaker.
[01:14:23] <zeeshan|2> whats a way to describe people who modify their cars
[01:14:28] <zeeshan|2> "automotive enthusiasts?"

[01:15:08] <malcom2073> zeeshan|2: Sure
[01:15:16] <malcom2073> Also gearheads
[01:15:19] <zeeshan|2> haha
[01:15:23] <furrywolf> there's a wide variety of people who modify their cars.
[01:15:32] <malcom2073> Typically used to describe people who like to modify muscle cars though
[01:15:42] <zeeshan|2> im trying to say more like
[01:15:43] <malcom2073> tuners if they like to modify foriegn cars
[01:15:49] <zeeshan|2> people who modify their cars to be faster
[01:15:49] <zeeshan|2> etc
[01:15:51] <CaptHindsight> nah this is IRC, car hackers :)
[01:16:00] <furrywolf> "rednecks", "wheelers", "ricers", "tuners", "tweekers", "car thieves"... :P
[01:16:06] <malcom2073> zeeshan|2: Actually faster, or Fast and Furious faster?
[01:16:26] <zeeshan|2> haha MacGyverX
[01:16:27] <zeeshan|2> malcom2073: !
[01:16:42] <malcom2073> Tuners or gearheads are the two terms I hear a lot
[01:16:44] <furrywolf> and a whole bunch of racial slurs, especially for the people who put 22" rims on an escalade.
[01:16:49] <malcom2073> Depending on the car type
[01:16:52] <SpeedEvil> 'the deceased'
[01:17:17] <CaptHindsight> it used to be called a "hobby"
[01:18:04] <malcom2073> It also used to not involve computers
[01:18:53] <CaptHindsight> they weren't labeled by their hobby, they just had a hobby
[01:19:09] <furrywolf> "petrolhead", "kustomizer", "chav" (if you see a mexican driving a lowered lincoln...), umm....
[01:22:08] <zeeshan|2> ill use a generic term :P
[01:22:31] <malcom2073> Automotive performance enthusiest
[01:23:07] <furrywolf> the first two of those are pretty generic. :P
[01:23:18] <furrywolf> although I only hear petrolhead in british stuff.
[01:23:39] <furrywolf> and kustomizing is a whole separate subculture...
[01:23:54] <andypugh> I thought we were the only ones with chavs too
[01:24:00] -!- tjtr33 has quit [Quit: Leaving]
[01:24:04] <malcom2073> I'd never heard the term chav
[01:24:46] <furrywolf> malcom2073: chavs are those people who backwards baseball caps, baggy pants, and lowered cars that scrape on every speedbump or driveway.
[01:24:46] <SpeedEvil> It's UK
[01:25:21] <furrywolf> and annoyingly loud stereos, usually blaring the stupidest of the stupid of rap music, with the windows down, while they drive with one hand and the seat tilted all the way back so they can't see over the dashboard.
[01:25:38] <andypugh> https://en.wikipedia.org/wiki/Chav
[01:26:08] <malcom2073> hm
[01:26:25] <malcom2073> Yeah that brings an image to mind, we don't have that sort around here heh
[01:26:45] <furrywolf> Chav is used in the US too, although "wigger" is usually used instead.

[01:32:54] <malcom2073> Oh, I got better pictures of my lathe now: http://mikesshop.net/?p=458
[01:32:56] <malcom2073> second half of the post
[01:32:59] <malcom2073> first half is the southbend
[01:33:25] <furrywolf> I saw a nice unimat teeny tiny lathe at a yard sale today, but wasn't going to spend $350 on it.
[01:33:34] <zeeshan|2> im suprised wiki makes no mention of andypugh being a chav
[01:33:36] * zeeshan|2 hides
[01:34:00] <andypugh> I don’t have enough style to be a chav
[01:34:04] <malcom2073> Heh
[01:34:13] <zeeshan|2> you just nered to wear a big gold chain while riding your bike
[01:34:19] <malcom2073> furrywolf: We have the big smoky truck group here, we just call them hicks.
[01:34:24] <zeeshan|2> malcom2073: wow you ricer
[01:34:33] <zeeshan|2> ORANGE or red handles!
[01:34:41] <malcom2073> Haha what?
[01:34:47] <zeeshan|2> on your lathe
[01:34:49] <zeeshan|2> nice lathe
[01:34:50] <zeeshan|2> btw
[01:35:03] <furrywolf> malcom2073: nah, they're not hicks. these are people with brand new (2014 or 2015 model) dodge diesel trucks with $10k of modifications.
[01:35:06] <zeeshan|2> is that belt cover factory?
[01:35:08] <malcom2073> Black handles
[01:35:10] <malcom2073> furrywolf: Ohhhh
[01:35:18] <zeeshan|2> what
[01:35:21] <zeeshan|2> they're orange on that website??
[01:35:22] <malcom2073> zeeshan|2: Why ricer though? <- Confused
[01:35:30] <malcom2073> Oh on the soutbend
[01:35:31] <zeeshan|2> see ricers will have a black car for example
[01:35:36] <andypugh> malcom2073: I see your SB has dual-unit handwheels. Do they turn together or does one move ever so slighly more slowly?
[01:35:36] <malcom2073> yeah, ignore the southbend, I'm selling that.
[01:35:37] <zeeshan|2> and they'll put white door handles
[01:35:39] <zeeshan|2> or yellow handlkes
[01:35:40] <zeeshan|2> lol
[01:35:45] <zeeshan|2> its called "accenting" the car
[01:35:46] <zeeshan|2> so lame :p
[01:35:48] <furrywolf> it's a thing you do when you sell your first hundred pounds of outdoor, I think.
[01:35:53] <zeeshan|2> i see it a lot on bikes
[01:36:09] <malcom2073> Lol
[01:36:13] <malcom2073> andypugh: I've never looked close enough to be sure

[01:36:42] <malcom2073> I have about 100 1.5x3ft boards
[01:36:45] <malcom2073> yours if you pick them up
[01:36:50] <zeeshan|2> is your lathe a 12x36
[01:36:52] <andypugh> On my Holbrook there is internal gearing so that the mm scale moves fractionally differently. It’s a bit daft, to be honest.
[01:36:54] <zeeshan|2> cause it looks very similar to mine
[01:36:56] <furrywolf> we just call them "growmobiles".
[01:37:21] <malcom2073> zeeshan|2: 37, It's a rebranded Grizzly G9249

[01:37:51] <malcom2073> Bwahaha
[01:37:52] <furrywolf> that page is never going to load.
[01:37:59] <malcom2073> Is it loading full sized thumbnails?
[01:38:00] <malcom2073> Lame plugin

[01:38:37] <furrywolf> yes, they're the full-size image, just resized in the browser.
[01:38:44] <furrywolf> so trying to load that page actually loads every full-size image.

[01:39:00] <malcom2073> I'll put that on my list to fix
[01:39:01] <malcom2073> sorry :P
[01:40:14] <malcom2073> zeeshan|2: FWIW, I bought the lathe like that
[01:40:26] <malcom2073> And no, that shield isn't stock
[01:40:45] <malcom2073> I have the stock shields, the guy replaced them with that for some unknown reason
[01:40:57] <zeeshan|2> looks nicely made
[01:41:00] <zeeshan|2> thats why i commented
[01:41:08] <zeeshan|2> (southbend)
[01:41:42] <malcom2073> It is, welded together and all, with a piano hinge
[01:44:38] <furrywolf> I guess I need to head to the local junkyard monday and ask about those clips... I've heard rumors they no longer let you wander around the yard unattended, due to insurance company bullshit, which means they'd have to charge a lot more.
[01:46:11] <malcom2073> lame
[01:47:07] <zeeshan|2> insurance aint it

[01:59:17] <furrywolf> ThisSucks: I wasn't using it to describe a motorhead.
[01:59:38] <furrywolf> much like "car thief", it was to give examples of people who might modify a car.
[02:00:10] <furrywolf> tweekers often modify their vehicles. sometimes by taking them apart into every single possibly dismantled component without ever putting anything back together. at 4am.
[02:00:44] <andypugh> Well, yes, but some of us don’t need to be on drugs to do that sort of thing.
[02:01:17] <furrywolf> there's a set of 6 clips for $10 on ebay with free shipping... probably should just get those. if the junkyard isn't letting you pull your own parts unsupervised, they'll charge that to watch me pull them...
[02:02:00] <furrywolf> andypugh: oh no, you need to be on drugs to do what tweekers do.
[02:02:23] <furrywolf> you've apparantly never seen anything truely tweeked on. :)

[02:30:10] <PetefromTn_> Wow what a miserable trip I just took...
[02:34:36] <zeeshan|2> what happened
[02:35:23] <PetefromTn_> well my stepson just went to basic Training for the US navy
[02:35:46] <PetefromTn_> and my family and I decided to drive up to north Chicago where the ceremony was held
[02:36:18] <PetefromTn_> GOOD LORD that was a miserable trip... I have never seen such shitty roads and horrible traffic patterns in my entire life
[02:36:23] <zeeshan|2> hehe
[02:36:35] <PetefromTn_> according to GPS it was SUPPOSED to be about 9 hours or so
[02:36:48] <PetefromTn_> it took us almost 13 hours ONE WAY to get there
[02:37:11] <zeeshan|2> sounds like a mission!
[02:37:16] <zeeshan|2> was it at least a scenic drive?
[02:37:31] <PetefromTn_> My poor vehicle took some kinda beating on the roads and MASSIVE potholes all the way from Louisville to Chicago
[02:38:20] <PetefromTn_> the only thing I would be able to even come close to calling Scenic was the massive installment of HUGE windmills we saw somewhere between Indianapolis and Chicago
[02:39:02] <PetefromTn_> we drove into Chicago downtown after the ceremony to see the city and get some of their World Famous Thick Crust Pizza
[02:39:15] <PetefromTn_> that is one crazy city...
[02:39:27] <PetefromTn_> there seemed to be NO turning lane lights anywhere
[02:39:46] <PetefromTn_> so GOD FORBID you have to go left at a light you better pack a lunch
[02:40:21] <zeeshan|2> lol
[02:40:56] <PetefromTn_> we left after we dropped him back off to report in at about 4:30 PM and did not get home until 6:15 this morning...
[02:41:14] <zeeshan|2> did you stop over somewhere?
[02:41:17] <zeeshan|2> or continuously drove
[02:41:30] <PetefromTn_> we just wanted to get back home so we drove thru
[02:42:03] <PetefromTn_> I swear my bed never felt so good as it did when I fell asleep this morning LOL
[02:42:08] <zeeshan|2> hehe
[02:42:30] <PetefromTn_> on the upside I am REALLY glad we went up to see the ceremony it was amazing
[02:42:40] <PetefromTn_> and the Pizza was pretty damn good too hehe
[02:43:29] <PetefromTn_> Chicago was really a cool city.....but I NEVER WANT TO GO BACK THERE AGAIN!
[02:47:45] <PetefromTn_> I think someone should get their ass kicked for the absolutely horrible roads and detours and traffic patterns in Louisville too....what a joke that place is.

[03:24:38] <furrywolf> progress! I'm fairly sure the problem with the first eu6500is is the missing cylinder head cowling.
[03:25:35] <furrywolf> the cooling fan is pressurizing the case without it. opening one of the side access panels lets the pressure out, and the surging stops.
[03:27:32] <furrywolf> it looks like just a cosmetic cover, but....
[03:29:54] <furrywolf> it's one of those problems where every time you open the access cover it starts working, and stops working again as soon as you shut it. :)

[06:38:12] <just_pink> hmmm
[06:40:23] <just_pink> ok.. other subject,
[06:41:02] <just_pink> how I make the feed rate calculation for 0.5mm drill bit with 1000 rpm
[06:44:09] <XXCoder> http://www.custompartnet.com/calculator/drilling-speed-and-feed
[06:51:25] <just_pink> I'm try to work with it...
[06:52:44] <just_pink> 0.5mm in in = 0.0196850394 inches
[06:53:01] <fenn> why do people mix metric units and minutes? sort of defeats the point of going metric
[06:54:48] <just_pink> fenn: I like the metric system
[06:54:59] <fenn> me too
[06:55:19] <fenn> stuff like mm/min makes calculations harder
[06:56:00] <XXCoder> I prefer SI
[06:56:08] <XXCoder> too bad usa dont use it outside science
[06:57:41] <just_pink> XXCoder: Please tell me what size of drill bit is 0.109375 in?
[06:58:22] <XXCoder> https://www.google.com/search?q=0.109375+in+to+mm&gws_rd=ssl
[06:58:35] <XXCoder> I love google convertor. looks like 2.8 mm roughly
[06:58:45] <just_pink> XXCoder: no
[06:58:55] <fenn> 7/64 according to https://en.wikipedia.org/wiki/File:Decimal-fraction_equivalents--v0006.png
[06:58:55] <just_pink> It's 7/64 drill bit
[06:59:10] <XXCoder> ah yea didnt have chart handy
[06:59:24] <fenn> actual 7/64 drill bit will be smaller than that because drill bits cut oversize
[06:59:33] <just_pink> XXCoder: go metric!
[06:59:45] <XXCoder> heh
[06:59:55] <XXCoder> right now I can only use 6 mm tools
[07:00:02] <XXCoder> I has ball em and em 6 mm
[07:00:14] <XXCoder> has no way to use other sizes for now
[07:00:46] <fenn> closest would be a #35 drill?
[07:01:24] <just_pink> yes
[07:01:31] <just_pink> https://www.boltdepot.com/fastener-information/us-tap-drill-size.aspx
[07:01:52] <just_pink> I've used it for the tapping..
[07:01:58] <just_pink> 6-32
[07:02:48] <just_pink> I want to use metric but I can't find some in reasonable price
[07:05:50] <fenn> has anyone used a meshing belt drive system like this for cutting metal? how did it work out? http://mikesshop.net/wp-content/uploads/2015/01/DriveSystem.png
[07:07:36] <fenn> it seems like it would be pretty stiff if you used fiberglass belt
[07:09:58] <XXCoder> just_pink: maybe aliexpress
[07:10:30] <fenn> i would be worried about the quality of no-name chinese bolts
[07:10:40] <just_pink> fenn: belt Is very good for speed, but I Think it will make a-lot of flex if you will try to penetrate hard material, I'm nice for simple stuff.. but for metal stay with ballscrew with nice servo motor.
[07:11:30] <fenn> the belt is only stretching over a short distance though

[07:11:38] <just_pink> XXCoder: I start to order from fastenal.. but I start with the heatsnk stuff before that, so I stay with the 6-32..
[07:11:43] <XXCoder> fenn: geared belt?
[07:12:04] <fenn> i'm not sure what it's called or if it even has a name
[07:12:32] <fenn> the teeth of the belt mesh with grooves on the table, or another belt glued down to the table
[07:14:51] <archivist> I think belts were created for power transmission, not position control, I have never seen a positional accuracy spec yet from a belt maker
[07:15:08] <just_pink> fenn: the shapeoko work with that..
[07:15:11] <just_pink> Junk.
[07:15:44] <fenn> the shapeoko doesn't mesh with anything on the table
[07:15:52] <fenn> it's just a belt drive
[07:16:21] <just_pink> what do you mean by "on the table"
[07:16:40] <fenn> underneath where the belt is
[07:16:53] <archivist> there is an inverse belt/rack it engages with
[07:17:46] <fenn> the accuracy would come from the rack, not the flexible belt
[07:18:23] <just_pink> on the table you need to put the workpiece, all the driving parts should be under the table
[07:18:37] <fenn> if the belt and rack don't agree on how many teeth per inch then the belt will get looser or tighter along the distance traveled
[07:18:52] <fenn> sorry, table was the wrong word
[07:19:09] <just_pink> fenn: If the belt is flexi you will get very poor accuracy
[07:20:49] <fenn> i agree things like this are not stiff enough: http://www.ecmarsh.com/cnc/images/router_06.jpg
[07:21:04] <fenn> but i'm talking about something else, where only a small part of the belt can stretch

[08:13:45] <just_pink> I need dc motor like to the cell phone virator motors.. but with gear..
[08:14:43] <archivist> bz I make gears, the worm/gear in the rotary are my biggest error term I think
[08:15:27] <bz> archivist: bit recursive since milling the worm yourself would require a rotary in the first place, right?
[08:15:27] <fenn> archivist: would it be better to use a cycloidal gear instead of a worm

[08:15:46] <archivist> fenn, hell no
[08:16:49] <archivist> bz, the rotary sold by Vertex actually has a usable specification and does not cost too much
[08:18:34] <archivist> we had some errors at the last place I worked and it turned out most of the dividing heads were rubbish, only one measured ok
[08:18:58] <just_pink> XXCoder: step number 1 get a 3d printer, step number tow make JUNK!!
[08:19:06] <XXCoder> whee new term dividing head
[08:19:37] <archivist> a bad one has a sawtooth error term at worm wheel rate
[08:19:42] <XXCoder> interesting on dividing head

[09:16:17] <fenn> apparently this "belt on belt" drive system was commercialized and they have some datasheets up http://bell-everman.com/products/linear-positioning/servobelt-linear-sbl
[09:21:07] <fenn> recommended maximum payload 300lb accuracy 125um (over what distance? unclear)
[09:21:27] <XXCoder> accuracu 125 um across 125 um
[09:21:43] <fenn> says over full travel but i can't find that value
[09:22:22] <fenn> elsewhere it said "up to 50 meters" but i find that hard to believe 125um/25m
[09:22:56] <fenn> 2.5ppm error
[09:24:09] <archivist> there are many impossible specifications on the web
[09:24:26] <XXCoder> -1um across infinity m
[09:24:32] <fenn> it's just an incomplete datasheet
[09:24:42] <archivist> time to set the local laws on advertisers
[09:25:13] <fenn> i think the full travel is 5.5m
[09:25:56] <archivist> so many are confusing resolution with accuracy too
[09:26:28] -!- GeorgeHahn has quit [Read error: Connection reset by peer]
[09:26:29] <fenn> no they have different values for rotary encoder vs linear encoder, the linear encoder is +-4um
[09:26:39] <fenn> but usually rotary encoders have higher resolution
[09:27:04] <archivist> so that is the encoders spec not the belt :)
[09:27:26] <fenn> also they give values for repeatability which says "depending on acceleration profile"
[09:27:43] <fenn> so i don't think it's just resolution
[09:28:51] <archivist> lots of error terms which should all be included in and total accuracy figure
[09:28:58] <archivist> and/any
[09:29:28] <XXCoder> any facts not stated I assume is really bad, for example if not stated any error across x distance
[09:29:36] <XXCoder> I assume one meter per meter :P
[09:30:16] <fenn> it's 125um/5.5m i just didn't see the field because it was labeled "maximum length"
[09:30:43] <trentster> howdy all
[09:30:56] <archivist> I have been in the discussions when writing specs, seeing what we could/could not say :)
[09:31:03] <XXCoder> hey
[09:31:31] <fenn> well anyway the value seems about right based on my experiences with belts
[09:34:34] <trentster> what do you guys do as best practice when cnc drilling a hole (I normally use spiral cycle) and a end mill very rarely drill bit. That being said I am trying to figure out whats the whole over sizing to use as someone mentioned dont go too tight with hole sizes and accuracy when building a cnc part. So for e.g if making an M8 hole through flatstock for a bolt to go through it into a tapped M8 hole in a 3060 extrusion - should I oversize a certain pec
[09:34:55] <trentster> instead of 8mm hole go 8.5mm or 8.2mm etc
[09:35:08] <trentster> whats the consensus here?
[09:35:32] <trentster> too tight not enough wiggle room too loose too much room for play as the machine move , vibrates etc
[09:36:34] <fenn> M8 cap screw head is 12mm so something less than 12mm :)
[09:36:49] <fenn> 9mm would probably be fine
[09:37:10] <fenn> the point of bolts is to clamp things, not to accurately locate them
[09:37:22] <fenn> if you are worried about getting knocked out of alignment use a roll pin or dowel pin
[09:38:32] <jdh> http://www.draughtsman.co.uk/information_images/mechanical/clearance_holes.htm
[09:41:00] <trentster> http://monosnap.com/image/B21auyEMLnMl8PEcJ8Ogwq0sajYpPw
[09:42:16] <trentster> fenn: from the test sholes I milled today I would say that even 8.5mm for a M8 hole is pushing it
[09:42:53] <fenn> is it too small or too big?
[09:43:26] <trentster> also found that pocketing a hole with a smaller bot and stepover produces by far the cleanest most production quality looking hole
[09:43:45] <trentster> fenn a touch too big
[09:44:00] <fenn> is the hole actually 8.5mm in diameter?
[09:44:07] <trentster> or too much wiggle room
[09:44:30] <trentster> yes its exactly 8.5 verified with calipers
[09:44:32] <XXCoder> http://www.cracked.com/photoplasty_1606_13-movie-heroes-who-caused-mass-civilian-casualties/ funny
[09:44:39] <XXCoder> expecially #7
[09:44:45] <fenn> eh whatever if you don't have enough slop you can always drill it out later
[09:45:19] <trentster> busy looking at the hole walls with a microscope at the moment to see if I can find some chatter markes
[09:45:23] <trentster> *marks
[09:45:46] <trentster> I guess the purpose of these questions is to try and figure out what is industry practice
[09:45:55] <jdh> that's way too much thought for a bolt hole
[09:46:48] <fenn> the chart jdh linked to is "industry practice"
[09:47:00] <trentster> e.g. if you had to buy a cnc machine that self assembles lets say a "Shopbot" for argument sake, what size would they use for a hole where a M8 Screw goes through - always exactly 8mm or do they leave 0.1 additional wiggle room.
[09:47:04] -!- The_Ball [The_Ball!~ballen@42.80-202-192.nextgentel.com] has joined #linuxcnc
[09:47:22] <fenn> never exactly 8mm
[09:47:34] <trentster> oh sorry jdh I missed that link, looking now
[09:47:50] <XXCoder> so far at work all holes had tolences
[09:47:57] <jdh> google 'metric clearance hole'
[09:48:00] <XXCoder> typical is around .01
[09:48:14] <XXCoder> has seen .003" tolences though
[09:48:24] <fenn> not for a bolt hole
[09:49:29] <trentster> jdh: thanaks thats exactly what I was looking for :-) and I guess CNC machines fall into the "Close fit" category ;-)
[09:49:40] <syyl> a clearance hole for a M8 bolt/screw is 9mm
[09:49:50] <syyl> for regular tolerance
[09:50:00] <syyl> there is also "fine", then the hole is 8,4mm
[09:50:10] <syyl> or "coarse" then its 10mm
[09:50:13] <trentster> syyl: that way too big for CNC builds tho especially if everything is cad/cam designed and cnc cut
[09:50:19] <syyl> i didnt make this numbers up
[09:50:29] <syyl> thats DIN EN
[09:50:43] <syyl> and screws are not there to align anything
[09:50:49] <syyl> so clearance doesnt hurt
[09:50:49] <trentster> syyl: yeah jdh link calls "fine" = "Close Fit"
[09:51:03] <syyl> and makes the guy that has to screw that crap together not cry
[09:51:10] <Deejay> :D
[09:51:27] <XXCoder> then theres chinese tolerance which can be up to 15mm :P
[09:51:33] <syyl> yeah
[09:51:40] <syyl> you just need to stack washers
[09:51:44] <trentster> syyl it not the alighnment I am worried about its the introduction of vibrations and enertial forces over time that has more room to play into if bolts have lots of wggle room
[09:51:55] <trentster> or at least to my layman brain thats what makes sense
[09:51:55] <syyl> then the construction is faulty.
[09:52:08] <syyl> screws are not there to take shearing
[09:52:32] <syyl> when a screw connection is designed right
[09:52:54] <syyl> the parts are only held in position to each other by the friction introduced by the screws pressure
[09:53:03] <syyl> if the parts move against each other
[09:53:13] <syyl> wrong design on the screw connection
[09:53:36] <syyl> (more screws, pins that can take shearing, bigger screws or superglue)
[09:54:18] <trentster> syyl: yup - making notes
[09:54:27] <trentster> what does "stack washers" mean?
[09:54:31] <syyl> haha
[09:54:34] <syyl> you have a 20mm hole
[09:54:37] <trentster> 2 washers on top of each other?
[09:54:41] <syyl> and a M6 screw
[09:54:42] <trentster> is more effective than 1?
[09:54:50] <XXCoder> washers all way down
[09:54:51] <syyl> thats a total hack job ;)
[09:55:01] <syyl> farmers to that
[09:55:05] <fenn> it's for when you don't have a fender washer
[09:55:15] <syyl> or the fender washer is still to small :D
[09:55:30] <trentster> lol - I dont even know what a fender washer is.
[09:55:39] <fenn> a big washer with a tiny hole
[09:55:40] <trentster> need to take washer 101 class
[09:55:44] <syyl> :D
[09:55:50] <trentster> and not the one that involves girls and white t shirts.
[09:56:09] <syyl> that would be a class that I would take
[09:56:10] <syyl> .

[10:02:17] <trentster> syyl yup - thats exactly why I found a house next to a survivalist :-)
[10:02:24] <syyl> :D
[10:02:53] <trentster> if shit hit the fan just hop the wall and say howdy neighbour
[10:05:09] <trentster> so speaking of washers when does one use one of hose serated raised edge ones vs a stock standard flat ring?
[10:05:20] <syyl> if you want to marr the surface
[10:05:34] <syyl> they have no use whatsoever to secure a screw connection
[10:05:38] <syyl> same with spring waschers
[10:05:41] <syyl> or split ring
[10:05:45] <trentster> seriously tho, are they to be used together to aid in anto slippage?
[10:06:45] <trentster> yeah I kinda figured they were pretty useless bought a box when I was gathering cnc parts and have not used a single one
[10:07:55] <trentster> so basically normal steel flat washer and a bit of non permanent locktite on screw threads and all should be well in cnc machine land
[10:08:12] <trentster> at last from a screw coming loose from vibrations perspective
[10:08:28] <syyl> i try to stay away from anything washerish
[10:08:43] <syyl> especialy when screwing down critical parts
[10:08:53] <syyl> if you screw down a hardened linear rail
[10:08:59] <syyl> with a high grade screw
[10:09:08] <syyl> why put something soft between the part and the screw?
[10:09:18] <syyl> the washer will eventualy set itself
[10:09:24] <fenn> because something has to deform somewhere in the bolted joint
[10:09:24] <syyl> and the screwtension will lower
[10:09:33] <syyl> the screw will elongate

[10:09:44] <syyl> and thats what makes the connection strong
[10:09:50] <syyl> the washer will just mush
[10:11:10] <trentster> in my bit of testing a washer definately helps, more surface area and tention is a good thing, I have seen non washer screws vibrate loose and the ones with washers do not.
[10:11:40] <fenn> if you have a hardened bolt in a hardened thread clamping a hardened rail, won't the tightening torque go from 0 to infinite in a fraction of a turn?
[10:11:41] <syyl> take apart any real machinery
[10:11:42] <trentster> waiting for bad machine design retort …
[10:11:58] <syyl> there will be no washer under screws for linear rails, bearing blocks and so on
[10:13:49] * syyl is heading for the shop
[10:14:09] <trentster> off to buy washers are you :P
[10:15:09] <fenn> trentster: i think washers can help when bolting soft materials like aluminum and plywood
[10:15:25] <trentster> fenn yes I agree
[10:16:06] <fenn> that said, most of my machines don't use any washers
[10:16:17] <fenn> ones i've built i mean
[10:17:10] <fenn> i guess i tend not to make designs that have bolted joints under shear

[14:10:21] <trentster> I am not sure that an additional corss beam there will add any major structural benefit

[14:56:26] -!- PetefromTn_ has quit [Ping timeout: 240 seconds]
[14:56:44] <trentster> I created the CAM cycles in Cambam and ran the simulation in OpenSCAM
[14:56:55] <os1r1s> Tom_itx: Managed to get the e-stop and relays working yesterday. I need to get the PWM working. Right now its not respecting RPM, but it is working. I can turn it on, and use the spindle override to slow it down till it stops. It appears to use a different scale than software pwm and there is no way to specify the offset.
[14:57:08] <trentster> you just open a gcode file in openscam and it renders it like that for ya
[14:57:29] <trentster> http://openscam.org/
[15:03:58] * Deejay uses linuxcnc sim for checking the g-code
[15:10:22] <trentster> Deejay: yeah its nice as well but I dont run linuxcnc or linux on my design computer - in the house its all macs - in the garage /shop its linuxcnc
[15:10:39] <Sync_> just run a vm
[15:10:40] <Deejay> d'oh
[15:12:50] <os1r1s> trentster: Although I use simulators, there is nothing like running it through the exact host software. Whether its linuxcnc, mach3, or something else, you really should run it through that software. There are soooo many variables that will dramatically change what it does. And most of the sims don't support all canned cycles.
[15:14:44] <pcw_home> the Hostmot2 PWM scaling is the same as the software PWM ( that is 100% duty cycle when value=scale )
[15:15:02] <os1r1s> pcw_home: How do you take into account offset?
[15:15:21] <pcw_home> use the offset component
[15:16:56] <os1r1s> pcwhome: I was using setp pwmgen.0.scale 12285.7142857, setp pwmgen.0.offset 0.00232558139535
[15:18:23] <os1r1s> pcw_home: Now I’m using #setp hm2_[HOSTMOT2](BOARD).0.pwmgen.00.output-type 1, #setp hm2_[HOSTMOT2](BOARD).0.pwmgen.00.scale 4500
[15:18:36] <pcw_home> or if you have linearity issues, use lincurve
[15:19:14] <pcw_home> That cant be right, the scale should be the same...
[15:19:22] <os1r1s> Well, the weird thing is that the spindle override slider works great. If I go down to 15% it gets to a halt (300 rpm) and at 100% its up to 2800 rpm.
[15:19:45] <os1r1s> pcw_home: But it doesn't seem to respect RPM from M3 S500 for example
[15:19:50] <pcw_home> you have a 12285.7142857 RPM spindle?
[15:20:16] <os1r1s> pcw_home: No, its 0-2800. So does that mean the scale should be 2800?
[15:20:42] <pcw_home> yep
[15:20:53] <os1r1s> pcw_home: Ok, user error :)
[15:21:17] <trentster> os1r1s: good point and well taken
[15:21:23] <Tom_itx> until i added PID to mine i wasn't able to get respectable results
[15:21:33] <pcw_home> you should also set the PWM frequency to something the G540 likes
[15:21:45] <os1r1s> pcw_home: I set it to 50, which is what it recommended.
[15:22:10] <pcw_home> if this is for a VFD they are usually pretty good open loop
[15:22:21] <os1r1s> Tom_itx: You added a soft-start or ramp up for your motor, right? Is there any good instruction for that?
[15:22:32] <os1r1s> pcw_home: Its a KBIC-240 on a sherline
[15:22:47] <Tom_itx> it's built in the stock sherline driver
[15:22:48] <os1r1s> pcw_home: So not really a VFD, but similar in function.
[15:22:55] <trentster> gonna load up linuxcnc in a vm here for simulating cuts
[15:23:17] <Tom_itx> http://tom-itx.no-ip.biz:81/~webpage/cnc/spindle_drive/
[15:23:24] <Tom_itx> data sheets for the standard sherline drives
[15:23:39] <os1r1s> trentster: I killed a vise by not simulating in the actual software. The I/K were incremental instead of absolute, or vice-versa.
[15:24:04] <os1r1s> Tom_itx: I thought you were doing some ramp up in linuxcnc?
[15:24:53] <Tom_itx> no, the drive has an inhibit that when triggered causes the drive to start up with it's built in rampup
[15:25:10] <Tom_itx> so all i do is pulse that pin
[15:25:10] <os1r1s> Tom_itx: Got it. So you are using the built in ramp.
[15:25:21] <Tom_itx> yes, and it's ajustable
[15:25:37] <Tom_itx> it's in those pdfs
[15:25:51] <Tom_itx> i haven't changed it yet
[15:26:16] <Tom_itx> os1r1s, is yours a sherline?
[15:26:20] <os1r1s> Tom_itx: I've adjusted that part. But when the drive kicked out at 12%, it got pretty abrupt.
[15:26:25] <Tom_itx> and are you using the stock driver?
[15:26:37] <os1r1s> Tom_itx: Yeah, its the stock driver wired up to my G540
[15:26:56] <os1r1s> I've used it for a long time in mach3, but now I've seen the light :P
[15:26:59] <Tom_itx> ok does it require the interface board since it's GND is floating?
[15:27:12] <Tom_itx> http://tom-itx.no-ip.biz:81/~webpage/cnc/spindle_drive/kbsi_240d_manual.pdf
[15:27:17] <Tom_itx> i had to get that for mine

[15:27:50] <Tom_itx> if you fiddle around on it too much you'll find out
[15:28:38] <os1r1s> Tom_itx: The G540 has an interface and opto-isolator built in. But this doc is interesting. I don't thikn I've seen that interface.
[15:28:50] <Tom_itx> i hadn't either
[15:29:11] <os1r1s> Tom_itx: I'd really like one of the homman digispeed boards, but they are hopelessly out of stock
[15:29:18] <Tom_itx> but i found out early on i needed it
[15:29:48] <Tom_itx> i found one on ebay for pretty cheap
[15:35:20] <Tom_itx> since my drive didn't have reverse i had to add the SSD to enable it or it would kick pretty hard chaning direction but just one way... i forget now if it was going from FWD to REV or vise versa

[15:35:57] <Tom_itx> due to the natural brakeing the motor did
[15:36:00] <os1r1s> Tom_itx: That might have been why mine was cutting out. I have it on an SSR. I wonder if linuxcnc was cutting the relay when it got low.
[15:37:40] <os1r1s> Do you use your forward/reverse actively during milling operations?
[15:37:54] <Tom_itx> i haven't yet. i set it up to do rigid tapping
[15:38:00] <Tom_itx> and have tested it
[15:38:12] <os1r1s> That is where Iw as going next :)
[15:38:42] <Tom_itx> the code works but i haven't had a chance to put tool to metal yet
[15:38:54] <Tom_itx> been under the weather for a while
[15:39:07] <Tom_itx> air cut works good
[15:39:19] <os1r1s> Are you pausing between the reversal?
[15:39:31] <Tom_itx> just the time it takes for the relays to reverse
[15:39:45] <Tom_itx> there is a slight pause but not much
[15:39:53] <Tom_itx> you can see the spindle code in my hal
[15:40:14] <os1r1s> I know the doc said it would wear the motor quickly doing that. Thats why I thought I would ask
[15:40:38] <Tom_itx> i doubt it
[15:41:02] <Tom_itx> the brushes are made for one direction and may wear a bit more reversing but that's about it
[15:41:20] <os1r1s> Its not like these machines are continuous duty, so it likely doesn't matter
[15:41:57] <Tom_itx> not to me
[15:42:05] <Tom_itx> i'll never wear it out

[15:59:36] <os1r1s> Tom_itx: The stock one is a decal with 8 images and an optoreflective sensor

[16:01:32] <os1r1s> zeeshan|2: Taig mill with a sherline motor
[16:01:57] <Tom_itx> os1r1s, does your motor have external replaceable brushes?
[16:01:58] <os1r1s> Tom_itx: But I wasn't planning to have both. Just one or the other. It might make sense to use a sensor like you posted.
[16:02:05] <os1r1s> Tom_itx: Yes

[16:50:47] <furrywolf> Loetmichel2: craigslist, yard sales.
[16:50:51] <CaptHindsight> Loetmichel2: it will probably work better if you do it yourself, but it takes time that you might not have
[16:51:05] <Loetmichel2> right
[16:51:08] <furrywolf> the most I've spent for one is $50...
[16:51:10] <Loetmichel2> on both accouts
[16:51:26] <Loetmichel2> furrywolf: for an electric wheelchair? lucky one
[16:51:46] <furrywolf> Loetmichel2: people's parents/relatives pass away and they clean out the house.
[16:52:06] <Loetmichel2> http://www.ebay.de/itm/171867855353 <- last one i missed. and that was CHEAP because its deep in the woods and no delivery
[16:52:46] <pcw_home> They are common here for next to nothing because of our insane medical health system
[16:53:26] <furrywolf> the last one I got I made into a nice little flatbed cart... it was a heavy-duty model with a 350lb rating (I think), with 13" or 14" wheels (don't remember). bolted the motors to some aluminum bolted to a sturdy wooden frame, with a piece of plywood for the top (4ft by 2.5ft or so), with a pair of 55Ah AGMs...
[16:54:32] <furrywolf> used 10" pneumatic swivel casters for the front wheels, and reprogrammed the motor controller to "I'm not fucking senile" mode.
[16:54:47] <furrywolf> I've never seen one with hub motors like that.
[16:55:20] <Loetmichel2> furrywolf: these are for confined spaces
[16:55:43] <Loetmichel2> they are not larger than a normal hand-driven wheelchair
[16:55:54] <furrywolf> eh? it looks like it needs much more space than the one I took apart. it had six wheels with the driven wheels in the middle, so it'd turn in place.
[16:55:55] <Loetmichel2> wife needs one for going to the mall
[16:56:07] <Loetmichel2> she can walk a few meters, but then it hurts
[16:56:10] <Loetmichel2> (bad hip)
[16:56:27] <Loetmichel2> and i am tired of pushing her for miles and miles
[16:57:22] <furrywolf> one suggestion: unless .de is much more sane than .us, REPROGRAM THE MOTOR CONTROLLER. here at least, the default programming is "I'm mentally deficient as well as physically disabled", and it takes several seconds to do anything, turns really slowly, etc, all by design.
[16:57:46] <furrywolf> http://quest.mda.org/files/images/Quest2/18.4/permobil_m300.jpg that's the style I took apart last time... turns in place.
[16:58:38] <Loetmichel2> furrywolf: as it seems that i have to build it myself anyway i will use 2 2.2kw outrunners from my planes and build the motor controllers from scratch ;)
[16:58:46] <furrywolf> that works too. :P
[16:59:06] <Loetmichel2> do you think 4.4kw is too much?
[16:59:13] <furrywolf> no
[16:59:31] <furrywolf> given as a normal wheelchair is around that. :P
[16:59:49] <furrywolf> I think the peak on the last one I took apart was around 4.8kw...

[17:08:13] <furrywolf> http://www.wheelchairdriver.com/ has a lot of useful information for working with stock wheelchair components. I got the information for reprogramming the motor controller I used from there.

[17:15:11] <Loetmichel2> on the autobahn you still can have someone tailgating at 220++kmh ;)
[17:15:14] <CaptHindsight> it would be complete carnage here
[17:15:37] <Loetmichel2> furrywolf: "schiessscharte" in german very small and narrow opening
[17:16:15] * Loetmichel2 was on the reciving end of that a few times
[17:16:42] <Loetmichel2> my opel has a Vmax in ecess of 230ßkmh... and i DO drive it that fast
[17:16:42] <furrywolf> yes, that's the german word for an arrow slit... but I've still never seen something like that on a car. heh.
[17:17:10] <CaptHindsight> http://www.dailymail.co.uk/sciencetech/article-1083814/Pictured-The-robot-legs-help-people-weight-feet.html these might not help for some hip injuries
[17:17:22] <Loetmichel2> and then you get some grandma in a fiat 500 pulling out behind a semi at 90kmh ... without looking in the review mirror
[17:17:22] <furrywolf> my pickup has a top speed of 60mph... and I do drive it that fast! ... well, when there's a tailwind, at least....

[17:19:01] <Loetmichel2> "all hail ABS" ;)
[17:19:17] <furrywolf> I'm not sure if my subaru or my van is faster, but neither one goes anywhere near 230km/h.
[17:19:30] <Loetmichel2> my car weights around 2 metric tons
[17:19:53] <Loetmichel2> to get that from 230 to below 90 in virtually no space IS a challenge

[17:20:22] <furrywolf> my subaru MIGHT make it up to that speed, but I wouldn't trust its ability to handle safely that fast.
[17:20:45] <Loetmichel2> oh the omega drives well at that speed
[17:20:51] <furrywolf> engine would be right at redline too
[17:21:01] <Loetmichel2> it DOES overheat if you do that for more than about 20 minutes
[17:21:33] <Loetmichel2> the chiller in the front is a bit small
[17:21:53] <Loetmichel2> s/chiller/radiator
[17:21:53] <furrywolf> my speedometer only goes up to 140km/h. :)
[17:22:31] <Loetmichel2> i drive a german car
[17:22:37] <Loetmichel2> its made for these speeds ;)
[17:22:42] <CaptHindsight> was the car designed in Italy? :)

[17:22:59] <Loetmichel2> opel omega
[17:23:03] <Loetmichel2> german design
[17:23:23] <Loetmichel2> but the engine is made by BMW
[17:23:31] <Loetmichel2> the automatic gearbox alsp
[17:23:33] <Loetmichel2> also
[17:23:38] <furrywolf> I had a BMW. I sold it. worst vehicle I've ever owned.
[17:23:43] <furrywolf> I had a 740i.
[17:23:51] <furrywolf> PIECE OF CRAP.
[17:24:06] <Loetmichel2> so i think they just designed the radiator a bit too small
[17:24:08] <Loetmichel2> at opel
[17:24:30] <furrywolf> anything BMW touches has cooling issues.
[17:24:40] <Loetmichel2> hrhr
[17:25:05] <furrywolf> BMW has never made a vehicle that does not overheat nor, in recent times at least (since the '80s), doesn't have cooling system components randomly explode.
[17:25:23] <Loetmichel2> btw: that car was sold in the US by cadillac as a "catera"... but not as a station waggon i think
[17:26:19] <Loetmichel2> seems the americans dont like station wagons
[17:26:29] <furrywolf> eh? I have a station wagon. :P
[17:26:46] <CaptHindsight> they became minivans and SUV's
[17:26:48] <Loetmichel2> small station wagons
[17:27:05] <CaptHindsight> or now crossovers that don't do anything well
[17:27:05] <Loetmichel2> the omega is considered "big" in germany
[17:27:21] <furrywolf> I have a small station wagon. :)
[17:27:32] <Loetmichel2> its has the biggest trunk of all german driven cars for a fact
[17:27:52] <Loetmichel2> but for american circumstances i would classify it "small"

[17:28:36] <CaptHindsight> the minivan replaced the station wagon and since cars weren't inefficient enough they started marketing SUV's
[17:28:47] <Loetmichel2> its only 2 tons, 150hp 2.5 liters straight six turbocharged diesel
[17:28:58] <Loetmichel2> CaptHindsight: right ;)
[17:29:49] <Loetmichel2> AND the omega gets 26-28mpg ;)
[17:30:00] <PetefromTn_> I love my minivan ;)
[17:30:03] <furrywolf> I have three early '80s subaru station wagons, like http://stationwagonforums.com/forums/gallery/files/1/1983_subaru_gl_station_wagon8.jpg
[17:30:03] <Loetmichel2> thats much to efficient for american cars ;-)
[17:30:24] <furrywolf> one of them got totalled a month ago by an inattentive driver not noticing it was time to stop.
[17:30:37] <Loetmichel2> furrywolf: mine is from 2004
[17:30:40] <PetefromTn_> I got 22 mpg on the recent trip to Chicago with it full of junk and my whole family...
[17:30:45] <Loetmichel2> sadly thats the last one i will get
[17:30:46] <furrywolf> one of them I bought a couple weeks ago. haven't driven it yet, needs more repairs and registration.
[17:31:00] <Loetmichel2> opel ceased to build them in december 2003
[17:31:04] <CaptHindsight> PetefromTn_: where did you end up stopping for pizza?
[17:31:12] <PetefromTn_> Giardino's
[17:31:22] <furrywolf> I have a 1983 and two 1984s. the 1983 is the one that's now a fair bit shorter.
[17:31:24] <PetefromTn_> I am not sure I spelled that correctly
[17:31:32] <CaptHindsight> giordanos
[17:31:46] <furrywolf> one of them I put in a larger engine. that's the one that MIGHT make it up to your road speeds... but the suspension was never meant to go that fast.
[17:31:51] <PetefromTn_> it was decent but I am not used to pizza with the sauce on the top..
[17:32:01] <PetefromTn_> yeah Giordano's
[17:32:01] <CaptHindsight> recall which one? where it was near?
[17:32:08] <PetefromTn_> it was down from the pier
[17:32:18] <PetefromTn_> big place inside
[17:32:23] <PetefromTn_> two story
[17:32:31] <PetefromTn_> with the pizza ovens right near the entrance
[17:32:46] <furrywolf> best pizza I've had was some little town in the middle of the woods in new jersey. yes, NJ has parts of the state that are in the middle of the woods.
[17:32:48] <CaptHindsight> the touristy part of town
[17:32:52] <PetefromTn_> yup
[17:33:30] <furrywolf> we were offroading my truck through the woods on old access roads, came out by some little town in the middle of nowhere, saw the one restaurant in town was a pizza place, decided to stop for lunch...
[17:33:33] <PetefromTn_> I have always heard they make awesome deep dish chicago style pizza.... it was good...but I think I have had sicilian pizza other places that was better
[17:33:51] <CaptHindsight> locals don't really eat it
[17:34:06] <PetefromTn_> really heh
[17:34:11] <CaptHindsight> it's just been marketed to death
[17:34:31] <PetefromTn_> like I said it is good and THICK but I did not care for the sauce all over the top like that..
[17:34:40] <PetefromTn_> we have some leftovers we might eat for dinner tonight LOL
[17:34:55] <furrywolf> I'm not a big pizza fan... the only time I eat pizza is when I'm with other people who insist on it. heh.
[17:35:14] <PetefromTn_> I love a good pizza but not my favorite food overall
[17:35:21] <furrywolf> I much prefer a good curry. :)
[17:35:28] <PetefromTn_> yeesh
[17:36:22] <PetefromTn_> I could not believe the traffic and chaos of driving in Chicago surface streets tho....what a freaking mess!!
[17:36:47] <CaptHindsight> especially on a weekend
[17:37:00] <PetefromTn_> I almost killed an old lady on a bicycle when I tried to make a left turn at a light....heh
[17:37:13] <PetefromTn_> just nutz
[17:37:14] <CaptHindsight> you get the hang of it
[17:37:20] <PetefromTn_> no thanks LOL
[17:37:46] <CaptHindsight> it's far worse in other large foreign cities

[17:39:20] <CaptHindsight> it can take an hour to drive 5 miles during rush hour in the city
[17:39:22] <PetefromTn_> I suppose it would be cool living there if you don't have a car and take public trans or ride a bike everywhere...there are lots of neat stores and restaurants
[17:39:30] <furrywolf> one of these days I'll try making curry pizza... start with a pizza crust, but put curry sauce, tandoori chicken, dal, chana, chunks of paneer, etc....
[17:39:35] <PetefromTn_> Oh at least an hour LOL
[17:39:55] <furrywolf> I got some advice from a NY cabbie once: "Never use turn signals. they let people know what you're doing."
[17:40:02] <CaptHindsight> maybe for a while since it's new to you
[17:40:44] <PetefromTn_> I sure as hell would not want to go back there for anything more than a day visit and if I did I would fly in and take the rails into town.

[17:41:24] <CaptHindsight> after the few museums and similar all that left is shopping and eat/drinking
[17:41:38] <furrywolf> I'm at home on dirt roads in the hills.
[17:41:39] <PetefromTn_> yeah there are lots of nice streetside deli's and cafe's
[17:41:57] <PetefromTn_> with outdoor seating
[17:42:36] <PetefromTn_> and some rather amazing buildings and of course the sears tower or whatever they are calling it these days. We wanted to go in but apparently it is $20.00 a person just to ride up in the elevator
[17:42:50] <furrywolf> it will always be the sears tower. :P
[17:42:56] <CaptHindsight> and it quite a walk up :)
[17:42:59] <furrywolf> they can claim it's called something else, but that won't change anything.
[17:43:02] <PetefromTn_> apparently not
[17:43:11] <CaptHindsight> and parking is >$30
[17:43:22] <PetefromTn_> yeah parking is INSANE
[17:43:30] <CaptHindsight> so $80 for a family of 4 + parking
[17:43:31] <furrywolf> I think it's supposedly the willis tower now, but it's still the sears tower.
[17:43:35] <PetefromTn_> we paid like $25.00 for the three hours we ate that pizza
[17:43:46] <CaptHindsight> that was a deal
[17:43:47] <PetefromTn_> and that was cheap apparently
[17:44:01] <CaptHindsight> not as bad a NYC
[17:44:20] <furrywolf> I've never been somewhere you have to pay for parking. heh.
[17:44:34] <PetefromTn_> hell we pay for parking even in knoxvegas here
[17:44:39] <furrywolf> the only place that had paid parking was the NJ boardwalk, so we just parked inland and hiked.
[17:44:40] <PetefromTn_> but it is just a couple bucks
[17:44:43] <CaptHindsight> at times I would park near a subway for free and take that downtown
[17:45:18] <CaptHindsight> it can take 30 minutes to drive around the block some days in the downtown area
[17:45:26] <furrywolf> I've never been on a subway or a train. lol
[17:45:30] <PetefromTn_> altho the last trip we made to downtown Knoxvegas we found a cool parking garage that is free after 6pm to help the downtown area so that was nice
[17:45:30] <Loetmichel2> furrywolf: the suspension of german cars IS made to go 200++kmh
[17:45:55] <Loetmichel2> ... but still the x1 of my wife FEELs unsafe doing so because it is so SHORT
[17:46:32] <furrywolf> my BMW handled much worse than my subaru. but, it was a 7-series. I believe they're intentionally designed to suck.
[17:46:33] <CaptHindsight> PetefromTn_: how was traffic from Great Lakes down to Navy Pier?
[17:46:38] <Loetmichel2> it starts jumping at every transverse bump on the street
[17:47:13] <PetefromTn_> great Lakes training center to Navy pier took about 1.5 with the lions share of that inside the city area
[17:47:15] <Loetmichel2> furrywolf: the 7 series bmws are made to feel "american" in suspension
[17:47:19] <furrywolf> the 740i had way, way, way, way too soft of a suspension, intentionally because it was designed for senile people who drive 55mph in the fast lane with their blinker on all day.
[17:47:34] <CaptHindsight> PetefromTn_: do you have tollways down there?
[17:47:42] <Loetmichel2> soft as fuck. "boat on the river" if you know what i mean
[17:47:44] <PetefromTn_> in knoxville?
[17:47:49] <furrywolf> it rolled horribly if you tried doing anything that would be considered corning.
[17:47:50] <furrywolf> yep
[17:47:59] <CaptHindsight> PetefromTn_: yes, or near
[17:48:00] <furrywolf> as I said, it's the worst car I've ever owned!
[17:48:07] <PetefromTn_> no we don't have tollways around here that I have ever seen
[17:48:29] <PetefromTn_> amazing the balls they have to actually charge tolls when the roads are a freaking disaster area
[17:48:39] <furrywolf> also, the 7-series auto tranny has 1st gear disabled. because the people who buy them want smooth rides, not scary things like acceleration.
[17:48:43] <Loetmichel2> the X1 of my wife however: you can feel in your ass rolling over a coin
[17:49:03] <CaptHindsight> depending on how far you go it can cost $8 one way to work from the burbs into the city
[17:49:15] <furrywolf> BMW managed to make a car with a 280hp V8 that couldn't break the tires free.

[17:49:59] <Loetmichel2> its off most of the time

[17:50:14] <Loetmichel2> i LIKE to do powerslides around corners
[17:50:24] <CaptHindsight> PetefromTn_: but after 20 years they need rebuilding, wash, rinse , repeat...
[17:50:39] <PetefromTn_> hehe
[17:50:39] <furrywolf> Loetmichel2: the problem wasn't the traction control... the problem was they disabled 1st gear, by design, so make it smoother.
[17:50:44] <furrywolf> so all starts were in 2nd gear.
[17:51:15] <CaptHindsight> PetefromTn_: this used to be ~100 yards down from Navy Pier

[17:52:27] <PetefromTn_> heh sure as hell does not look anything like that anymore anywhere around there..
[17:52:34] <Loetmichel2> the fact that the heavvy engine is in the front and the car os RWD adds to that, tho
[17:52:55] <furrywolf> I had to drive a company vehicle with tires like that... I don't remember the name, but it was something stupid like "ecoeconowear" or something else ungodly awful... sure, they might have gotten good gas milage and gone 100k miles... but they had NO traction.

[18:21:34] <furrywolf> you give someone like http://www.reaperpb.com/warpedfx/camo.htm (first google result) a nominal amount of money.
[18:22:24] <renesis> http://www.camodipkit.com/products.htm
[18:22:27] <renesis> is printed film
[18:22:43] <furrywolf> they give you a roll of film. you put the film on the water, spray it with activator, and dip your part.

[18:24:06] <CaptHindsight> it's just PVA film, you can print on that with an inkjet
[18:24:15] <PetefromTn_> The Navy work uniforms are a cool blue digital camo I have never seen befor
[18:24:59] <PetefromTn_> really? You can make your own hydrodip panels?
[18:25:17] <furrywolf> camo is very, very popular here. :)
[18:25:17] <CaptHindsight> did the patent just expire on hydrographics or something? all of a sudden there is a buzz about it
[18:25:18] <renesis> capthindsight: cool
[18:25:28] <furrywolf> people think this area is hippies, but nope... just us rednecks. :P
[18:25:35] <renesis> furrywolf: ya there are kids wear camo jumpsuits to school
[18:25:51] <renesis> not enough trees on campus for it to work
[18:26:08] <furrywolf> the hippies are going away, now this area is mostly rednecks vs tweekers.
[18:26:12] <CaptHindsight> http://www.solublon.com/pva_film.htm
[18:26:36] <CaptHindsight> it's also all over alibaba and similar sites
[18:27:08] <trentster> What width and height do you guys use for cutting profile cuts into aluminium with a fairly small diameter bit like 1/8 Inch? Do you think a triangular tab width of 2mm wide by 2mm heigh is sufficient.
[18:27:30] <furrywolf> PetefromTn_: http://www.reaperpb.com/warpedfx/patterns/wfx-camo-large/wfx-485-Tiger-Stripe-Navy-BDU.jpg ?
[18:27:56] <trentster> the aluminium stock is 12mm thick - I am trying to find the sweet spot between tab strength vs not having a ton of cleanup afterwards
[18:28:00] <PetefromTn_> yup like that but on a blue background
[18:28:01] <trentster> any suggestions
[18:29:13] <PetefromTn_> trentster what are you trying to do? full slot profile pass?
[18:30:49] <trentster> no doing about .5mm passes slow
[18:30:55] -!- arekm [arekm!~arekm@pld-linux/arekm] has joined #linuxcnc
[18:31:04] <trentster> yeah full slot
[18:31:20] <trentster> but depth of cut is tiny with each pass, so not much force
[18:31:32] <trentster> .5mm a pass
[18:32:24] <greg> 0.5mm is what I slot with 1/8"
[18:32:28] <PetefromTn_> for profiling in 6061 I usually do a full slot pass in reasonable depth steps of say .125 with a 3/8 endmill and leave a finish pass of .010 or .005" Tapered tabs work best in my experience due to the fact that the cutter never really stops just rises up so the larger the taper the better
[18:33:14] <trentster> *trenster goes to google for imperial to metric calculator
[18:33:58] <PetefromTn_> also I find that it is often BETTER to not use tabs at all and just leave a thin web at the bottom of the part and then flipping it over to champfer the other side or just deburr it with a whirlygig
[18:34:03] <greg> lol he said 3.2mm with 9.5mm endmill and 0.1- 0.2 finsih pass
[18:34:38] <PetefromTn_> yeah for the metric heads here sorry in advance LOL
[18:34:40] <trentster> greg thanks I got it
[18:34:58] <greg> one day we'll get rid of those infernal units, I'm doing my part.
[18:35:09] <trentster> one day the world will be a smart place and everyone will use metric!
[18:35:14] <trentster> :P
[18:35:17] <PetefromTn_> yeah those MM's are annoying
[18:35:28] <zeeshan|2> what is a tapered tab
[18:35:29] * Deejay slaps Pete ^^
[18:35:40] * PetefromTn_ grins
[18:36:10] -!- Computer_barf has quit [Ping timeout: 250 seconds]
[18:36:26] <PetefromTn_> zeeshan|2 tabs are little blocks of material left in areas around the perimeter of a part to allow you to hold the part securely yet cut it out ALMOST completely
[18:36:27] <trentster> heh - I mean come on - I found out the other day a US 2 by 4 peiece of wood has actually got nothing to do with those dimensions. :O
[18:36:31] <greg> I hate setting metric radius offsets for fractional tools
[18:36:47] <trentster> it would be logical for it to be 2 something by 4 something, but its not
[18:36:48] <greg> come on it WAS 2x4 before it dried
[18:36:57] <PetefromTn_> a tapered tab is basically a triangle instead of a square shaped tab
[18:37:02] <archivist> or got planed
[18:37:09] <zeeshan|2> ah PetefromTn_
[18:37:32] <zeeshan|2> long live imperial
[18:37:45] <PetefromTn_> hear HERE
[18:37:58] <zeeshan|2> what makes more sense
[18:38:10] <zeeshan|2> the part needs to be 1 meter wide
[18:38:16] <zeeshan|2> or 3 feet wide
[18:38:16] <t12> hexidecimal part sizing
[18:38:21] <zeeshan|2> :-)
[18:38:22] <t12> the computers will take over
[18:38:26] <trentster> zeeshan-lab: one day the die hards will be gone - and a child will ask their parents - whats this inch and foot thing?
[18:38:31] <trentster> ;-)
[18:38:44] <PetefromTn_> don't count on it hehe
[18:38:44] <zeeshan|2> metric's pitfall is it's not realistic units
[18:39:20] <t12> i def find imperial easier to work in
[18:39:21] <zeeshan|2> would you rather look at your foot to get an idea of foot
[18:39:32] <zeeshan|2> or look at the wave length of krypton 86
[18:39:36] <zeeshan|2> to figure out meter? :p
[18:40:12] <t12> thou and tenth seems really easy to work in
[18:40:24] <PetefromTn_> it pains me that Star Trek uses metric measurements....
[18:40:30] <zeeshan|2> gaga
[18:40:31] <zeeshan|2> haha
[18:40:47] <CaptHindsight> a meter is about a yard
[18:40:55] <archivist> gnats cock is a fine unit of measure we should all aspire to
[18:41:01] <CaptHindsight> close enough for most people
[18:41:04] <t12> stardate 41254.7
[18:41:06] <greg> I'm convince who ever created imperial unit had 12 fingers and toes
[18:41:06] <t12> I oiled the ways
[18:41:19] <PetefromTn_> archivist I always like RCH
[18:41:33] <pcw_home> 12 is a much nicer base than 10
[18:42:03] <trentster> real question btw - do scientists in the US work in feet and miles when working out equations like speed of light and latency calculations, if so poor them - that must be painful!
[18:42:05] <CaptHindsight> metric football field, 100 meters or 91.44?
[18:42:08] <greg> to bad id didn't catch on in weights
[18:42:36] <CaptHindsight> trentster: we use SI units
[18:42:40] <zeeshan|2> trentster: no
[18:42:57] <CaptHindsight> older engineers might still use imperial for some things
[18:43:21] <zeeshan|2> trentster: on research papers i usually put si unit (imperial unit)
[18:43:26] <zeeshan|2> to cater to both
[18:43:40] <trentster> CaptHindsight: sounds logical " 1. a system of physical units ( SI units ) based on the metre, kilogram, second, ampere, kelvin, candela, and mole, together with a set of prefixes to indicate multiplication or division by a power of ten"
[18:43:41] <CaptHindsight> not a big deal
[18:43:44] <zeeshan|2> the imperial unit for heat transfer is nasty
[18:43:50] <trentster> now just need to do the same and get rid of inches
[18:44:25] <PetefromTn_> what's all this get rid of stuff?
[18:44:38] <os1r1s> pcw_home: That got it working. Works perfect from 0-2800 now.
[18:44:55] <carper> i still use imperial for cabinet making but quite happy using metric
[18:45:03] <trentster> PetefromTn_: is "retire" a better word
[18:45:18] <CaptHindsight> PetefromTn_: do you freak out when handed drawing in metric?
[18:45:21] <PetefromTn_> how about we GET RID OF METRIC does that sound better
[18:45:30] <t12> death to commie units
[18:45:39] <archivist> I freak out at a ligne
[18:45:42] <PetefromTn_> CaptHindsight Honestly about a third of the drawings I get are metric so I am quite used to it
[18:45:43] <trentster> Leave inches where they belong - in the "adult film industry" :P
[18:45:53] <greg> I'm amused by how polarized unit discussions are
[18:46:22] <archivist> https://en.wikipedia.org/wiki/Ligne#Watchmaking
[18:46:22] <greg> I work in both, but always design in metric
[18:46:33] <CaptHindsight> I occasionally get some shop or fabricator that doesn't want metric files
[18:46:43] <PetefromTn_> I work in both but design in INCH whenever possible
[18:46:46] <archivist> 12 ligne to a french inch :)
[18:46:52] <CaptHindsight> or can't discuss and application in metric
[18:47:07] <CaptHindsight> has to be in thou or 10-thou
[18:47:18] <t12> i design and work in whatever the driving design's dimensions are already in
[18:47:27] <PetefromTn_> I would never do that...if it is in metric I would just convert everything myself and deal with it like I always do
[18:48:03] <PetefromTn_> then I go out back of the shop and curse and spit a bit hehe
[18:48:20] <CaptHindsight> is Australian foot ball in metric?
[18:48:56] <CaptHindsight> does that explain all the confusion? :)
[18:49:44] <trentster> lol - I think it would have been easier to talk about politics than Metric vs other inferior forms of measurement ;-)
[18:49:58] <CaptHindsight> metric alphabet
[18:50:13] <Rab> For electronics you have to be fluent in both.
[18:50:46] <PetefromTn_> inferior my ass ;)
[18:50:48] <archivist> you lot have it easy only inch and metric, those working in clocks and watches have some more units

[18:53:49] <pcw_home> Yep electronics parts use metric and inch pitches
[18:53:51] <pcw_home> both are arbitrary (our number system is also arbitrary and based on a lousy radix)
[18:54:13] <greg> Ball bearings seem to mix units on balls and race sizes. That is a metric size bearing will often have a fractional ball.
[18:54:27] <trentster> Lets just get rid of (retire for PetefromTn_ ) Pounds for now - we can tackle Inches later. Or perhaps ….
[18:55:01] <pcw_home> lets get rid of all stupid base 10 systems. metric has to go
[18:55:08] <trentster> Just get a unit of measurement for pounds that actually sound like a Pound - LB?

[19:04:09] <XXCoder> I love the spin wrong way myth. it's because it is techinically true, yet not true. water WOULD spin wrong way yes, but not in tiolets and sinks, there is much larger force affecting those

[19:05:07] <greg> they did a great job on those videos
[19:05:21] <greg> archivist, all explained in those videos
[19:06:04] <XXCoder> archivist: it isn't, that is what I said. it;'s toilet and sinks that don't, since other factors affect it too much to be changed
[19:06:35] <XXCoder> for it to be truly affected by hmm whats it called again, it has to be very still water and slowly drain
[19:06:41] <XXCoder> you will see direction of drain then

[19:56:06] <furrywolf> XXCoder: http://www.sogknives.com/powerlock-satin.html they also have several other styles, including spring-loaded blades, if you prefer.
[19:56:41] <XXCoder> looks nice
[19:57:05] <furrywolf> they have compound leverage, like a pair of tin snips, with two sets of pivot points... much better for gripping things.
[19:57:09] <PetefromTn_> I should make that drag knife thingy
[19:57:18] <Rab> furrywolf, this website looks like garbage without jawascript.
[19:57:46] <PetefromTn_> jawa?
[19:58:08] <furrywolf> it looks pretty bad with it, too.
[19:58:27] <greg> i carry an Access Card 2.0
[20:00:25] <furrywolf> I've tried leatherman, gerber, victorinox, and SOG... the SOG is definitely the best, in my opinion.
[20:00:47] <furrywolf> the supertool is second-best, but it breaks too easily, and still has the fit-and-finish issues leatherman has had ever since they moved to mexico.
[20:02:04] <furrywolf> the gerber is uncomfortable and the sliding pliers design just isn't as good, but they do have the carbide insert wire cutters.
[20:02:23] <furrywolf> the victorinox is shiny, smooth, polished... and useless.
[20:02:55] <renesis> thats how you sell things make money!
[20:02:59] <renesis> =\
[20:03:09] <syyl> the sog design is the most stupid thing in the world
[20:03:18] <syyl> why have the tools to be inside the handle?
[20:03:23] <syyl> and covered by those flaps?
[20:03:39] <furrywolf> the victorinox is well-built, but too light-duty.
[20:03:55] <syyl> the victorinox is like a supertool
[20:03:55] <syyl> Oo
[20:03:59] <syyl> at least mine :D
[20:04:34] <syyl> i stopped carrying it because it lacks the one hand opening blades
[20:04:49] <Rab> syyl, grip comfort is not to be underestimated IMO. I find most multitools to be really painful as pliers.
[20:05:01] <furrywolf> syyl: the flaps are optional (I keep mind off), and having them inside the handle keeps lint out, etc. it sounds like you'd be happier with some of their other models, like http://www.sogknives.com/powerassist-satin.html
[20:05:04] <syyl> when i need my multitool
[20:05:07] <syyl> i need it fast :D
[20:05:12] <Rab> So the flaps look awkward, but they address that problem.
[20:05:15] <syyl> otherwise i can use the propper tool
[20:05:27] <syyl> i need a blade *right now*
[20:05:36] <syyl> or needlenose pliers *right now*
[20:05:50] <furrywolf> syyl: which is why they make the one I just pasted, where the blades are spring-loaded, and open with the tool closed. :P
[20:05:52] <renesis> the flaps look clunky to use
[20:06:08] <renesis> would have to try them to see if they actually make the handles more comfy
[20:06:19] <furrywolf> yes. which is why I keep mine off.
[20:06:19] <furrywolf> they snap on
[20:06:22] <syyl> the powerassist looks like
[20:06:26] <syyl> "i dont want to use it"
[20:06:29] <furrywolf> they do make the handles more comfy, but I have tough redneck hands, and the compound leverage means you need a lot less grip force.
[20:06:32] <syyl> realy :D
[20:06:52] <renesis> mostly i think its the straight angled handles that make them uncomfortable
[20:07:07] <furrywolf> the victorinox looked like I'd break it the first time I used it. :P
[20:07:15] <furrywolf> someone I know has one, and it's good for looking pretty.
[20:07:16] <syyl> hrm

[20:10:04] <furrywolf> I want over-center locking, but in a compact yet strong package.
[20:10:36] <furrywolf> unlike the locking leatherman which is just a pair of vise grips with square handles...
[20:11:10] <greg> i didn't know about swisstool
[20:12:31] <greg> i've carry the same Tinker for 22 years
[20:12:36] <furrywolf> a friend had the gerbers since they kept giving them to him in the army, but they broke constantly, the sliding pliers would collapse and mangle your hand, they were uncomfortable,... but they did have the carbide wire cutters. except if you wanted a wood saw. then you couldn't get the carbide cutters. because they only have really stupid feature combinations...
[20:15:58] <PetefromTn_> I carry one of those folding utility blade lockback knives... had all sorts of knives and multitools and really got tired of having a blade that will not cut or that gets damaged so easily..
[20:16:49] <furrywolf> I have one of those too... and I always keep an Irwin Blue blade in it. they seem to suck the least. heh.
[20:17:28] <furrywolf> it's good for cutting things. it's bad for gripping things, turning screws, etc. :)
[20:19:25] <SpeedEvil> furrywolf: the annoying problem with DIY is you really want to forge it
[20:19:39] <PetefromTn_> yeah when I need to do that I grab a pair of pliers or a screwdriver ;)
[20:19:59] <XXCoder> never found multitools useful
[20:20:09] <furrywolf> PetefromTn_: how about when you're in your vehicle? someone else's vehicle? in a store? on a hike? somewhere outside on your property? at someone else's house? etc :P
[20:21:04] <PetefromTn_> Well like XXcoder said I never saw one of those multitools that was worth a damn and I have had a few of them. They might do one or two things decent but most things are just gimmicky
[20:21:46] <furrywolf> I use mine dozens of times. a day.
[20:22:12] <PetefromTn_> I did have one that had a 1/4 inch drive tool socket on it that you could put actual screw bits in that was at least useful
[20:22:23] <furrywolf> even if I'm home, it's quicker to flip it open than to walk to where a tool might be. :)
[20:22:27] -!- lerman has quit [Ping timeout: 250 seconds]
[20:22:31] <PetefromTn_> and the pliers are decent on most of them
[20:22:41] <syyl> and all nuts on your stuff are rounded over? ;)
[20:23:22] <furrywolf> syyl: no, the compound leverage makes sure they grip tight enough not to slip. :P
[20:23:36] <syyl> and you can always come back with vise grips
[20:23:39] <syyl> to finish them ;)
[20:23:48] <furrywolf> PetefromTn_: my SOG has a driver for 1/4" drive sockets. if you want to drive 1/4" hex bits, they have an adapter. www.sogknives.com/type/accessories/hex-bit-accessory-kit.html
[20:24:02] <furrywolf> syyl: see above. includes a socket driver. :P

[20:25:51] <XXCoder> even behind you
[20:25:53] <PetefromTn_> I know I had a gerber two of them actually and a leathermen and and
[20:26:05] <syyl> the funny thing is
[20:26:10] <syyl> whatever multitool you take
[20:26:20] <syyl> compare it to a proper tool
[20:26:23] <syyl> and you laugh :D
[20:26:59] <furrywolf> syyl: I use the pliers in my SOG in preference to actual pliers. the compound leverage rocks. :P
[20:27:12] <syyl> get a set of knipex wirecutters
[20:27:15] <syyl> and tell me again
[20:27:28] <syyl> cut 3mm piano wire
[20:27:50] <furrywolf> they have good wire cutters too. last week I was cutting barbed wire with them, cleaning up a friend's yard.
[20:28:44] <furrywolf> 3mm is probably about their limit for piano wire. I haven't kept track of what thickness hard wire I've cut with the hard-wire cutter they have.
[20:28:55] <furrywolf> I cut a bicycle cable housing once.
[20:30:57] <furrywolf> now here's a tool question... I want a GOOD machette. suggestions?
[20:31:24] <furrywolf> one that both springs AND holds an edge AND has a good large comfortable for big hands swinging it hard.

[20:33:01] <furrywolf> I am sick of chinese machettes. all garbage.
[20:33:18] <furrywolf> I think the one I have now is a corona, and it works, but it's still not ideal.
[20:35:01] <furrywolf> and I like a bit of blade weight, especially towards the tip.
[20:37:09] <PetefromTn_> sounds like you need to get a big chunk of blade steel and whittle yourself one up
[20:38:28] <syyl> i prefer the gas powered one Oo
[20:39:43] <furrywolf> PetefromTn_: a friend did that, from a truck leaf spring. :P
[20:40:04] <furrywolf> anneal, grind, temper, cut.
[20:40:05] <XXCoder> I recently watched one where guy makes one knife from drill bit
[20:40:48] <furrywolf> syyl: you can clear blackberries with a machete just as fast as with a string trimmer.
[20:41:01] <PetefromTn_> I like the one where the guy makes the cool ring from a penny LOL
[20:41:51] <furrywolf> probably faster, actually.
[20:43:37] <PetefromTn_> hacking apart beatiful delicious blackberry bushes seems VERY WRONG to me man...
[20:44:14] <furrywolf> PetefromTn_: clearly you don't live in an area where they take over everywhere they can.
[20:44:39] <furrywolf> here they grow with stems an inch thick, 30ft long, over your house, over your trees, over your cars,...
[20:44:59] <PetefromTn_> I pay like $5.00 for a tiny box of these beauties around here man so my wife can make them with home made whipped cream for desert~~
[20:45:35] <furrywolf> how's this for a deal: you can pick all my berries FREE as long as you take the plants with you. :P
[20:46:04] <furrywolf> they're a noxious weed here.
[20:46:07] <PetefromTn_> Shit I would if I could afford the trip and had a way to preserve them so they are juicy and fresh for perpetuity

[20:55:39] <PetefromTn_> no we only sell imperial endmills ;)

[20:56:29] <PetefromTn_> heh that is one STRONG woman...not half bad looking either
[20:56:42] <greg> petefromTN, yes even the people that buy from china only seem to sell imperial sizes, i checked shars.
[20:57:08] <PetefromTn_> ya think there is a reason for that? ;)
[21:01:21] <furrywolf> why are at least half the machetes currently made branded after idiots on tv? lol
[21:02:06] <SpeedEvil> There have to be really good chinese machetes
[21:02:07] <PetefromTn_> don't you know branding with idiots sells!!
[21:02:15] <SpeedEvil> I mean - bamboo is a thing
[21:02:40] <greg> only thing uncommon about what i'm looking for is the 40mm size, very small for a face mill
[21:02:48] <furrywolf> PetefromTn_: -grylls improves searches quite a bit. :)
[21:02:57] <PetefromTn_> I used to have a cheap home depot machete that I must admit to enjoying using to hack apart some parts of the shrubs on our house back when we bought it. there was something CAVEMAN about it..
[21:03:36] <PetefromTn_> or perhaps it was somewhat Crocodile Dundee
[21:03:49] <PetefromTn_> I dunno but I can dig it...;)
[21:03:56] <furrywolf> lol
[21:04:05] <XXCoder> lol
[21:04:06] <PetefromTn_> you actually can dig with it but its not good for the edge I hear LOL
[21:05:30] <furrywolf> I used mine to remove some 1.5" thick willow saplings recently... :P
[21:07:13] <furrywolf> with a sharp edge and a good swing, you can mow them down like grass...
[21:08:08] <PetefromTn_> with a sharp edge and a good swing you can probably mow down about anything with one heh
[21:13:16] <furrywolf> too many survival machetes with short blades... I want 18". heh.

[21:15:41] <PetefromTn_> aah
[21:16:14] <furrywolf> I got a pair of Fiskars pruning shears. they broke the first time I used them. I was not impressed. spent good money on them too.
[21:16:43] <furrywolf> bypass loppers, hand-held... the blades caught on each other, mushing both blades, ruining it.
[21:18:52] <ThisSucks> Perhaps something with on moving parts will serve better...
[21:18:57] <ThisSucks> on=no
[21:19:05] <furrywolf> the fiskars machete seems to have piss-poor ratings. I've never seen something with only 2 stars. ool

[21:21:42] <furrywolf> "After about 6-7 weeds (milkweed & other "soft" targets) the blade was bent like aluminum foil...it struggled to cut the thinest of weeds also. So in my opinion it's junk but it is cheap...it will make a great Halloween prop!"
[21:22:06] <furrywolf> "I have purchased other Fiskars items such as the axes and have had great experiances with them. HOWEVER this tool is worthless after just 2hrs of brush clearing... its main impact area is bent"
[21:22:27] <furrywolf> "Blade is thin and as flimsy as any $5 Chinese flea market machete. Within 30 minutes of first use it had bent repeatedly and permanently. The steel is just junk."
[21:22:43] <furrywolf> "Soft, poor choice of metal. No edge. Totally worthless. Any $5.00 machete is a better choice. "
[21:22:45] <furrywolf> etc, etc, etc.
[21:22:51] <furrywolf> so... no. I'm not getting the Fiskars one.
[21:23:06] * PetefromTn_ thinks furrywolf should spend less money of fiskars stuff and other expensive blade type items and spend more on a nice big mill and lathe :D
[21:23:32] <XXCoder> ool = OHH out loud
[21:23:40] <furrywolf> PetefromTn_: see, a machete actually does something useful, while a mill only does something fun...
[21:23:49] <PetefromTn_> I beg to differ
[21:23:54] <furrywolf> thus the budget for machetes exceeds the budget for mills.
[21:23:54] <XXCoder> furrywolf: can always make knifes out of drill bits like that guy LOL
[21:24:10] <furrywolf> XXCoder: a friend made a really nice machete out of a leaf spring.
[21:24:12] <PetefromTn_> I can make a lot more useful schtuff with my mill than I could ever do with a machete
[21:24:28] <furrywolf> XXCoder: annealed it, flattened it, ground it to the shape he wanted, re-heat-treated it...

[21:38:26] <Loetmichel2> rabbitfoo: missing a word in your sentence?
[21:38:27] <rabbitfoo> it already has ballscrews/motors/stuff fitted, but the old control is dead.
[21:38:33] <PetefromTn_> I guess that depends on how much you like the bridgeport LOL
[21:38:41] <rabbitfoo> OK... Just wondering if it was WORTH the effort to retrofit a bridgeport mill
[21:38:44] <syyl> just wanted to ask if its already an cnc machine
[21:38:48] <furrywolf> if it already has the mechanical bits, then it's definitely worth it.
[21:38:54] <Loetmichel2> a briodgeport miss ia a small knee mill isnt it?
[21:39:01] <Loetmichel2> mill
[21:39:19] <PetefromTn_> some of the bridgeport mills have some crazy proprietary millhead motors that are tougher to get power to
[21:39:44] <furrywolf> if your existing servo drives are still good and usable without the control, retrofitting it will be pretty cheap too.
[21:39:47] <PetefromTn_> I am talking about the larger CNC knee mills
[21:40:14] <Loetmichel2> google photos says ists aboutz the size of a deckel fp1
[21:40:17] <Loetmichel2> is that right?
[21:40:21] <PetefromTn_> I have a neighbor who owns a CNC EDM shop that has one that he is practically begging me to retrofit for him...
[21:40:55] <Loetmichel2> i would say thats worth a retrofit IF the ways are good to go
[21:41:03] <rabbitfoo> machine like this one: http://igor.chudov.com/projects/Bridgeport-Series-II-Interact-2-CNC-Mill/
[21:41:08] <Loetmichel2> if they are worn: trash it ;)
[21:41:45] <Roguish> PerefromTn: is the bp knee mill a 'series II' ?
[21:42:37] <PetefromTn_> the one he has is yeah I think so
[21:42:42] <Roguish> if it's 'worn' don't trash it. you may not get micron accuracy, but it's 5000 pounds of good iron and steel. crazy solid!
[21:42:43] <rabbitfoo> I *think* so
[21:42:52] <PetefromTn_> its not mine
[21:43:10] <Roguish> i have one in my garage/shop with linuxcnc running.
[21:43:23] <PetefromTn_> yeah I hear they are a beast of a mill
[21:43:51] <Roguish> old tape drive dc motor motors with my lmd18200 drives.
[21:44:13] <Loetmichel2> Roguish: ok, i revise that: if its ways are worn badly: give it so someone with the patience to scrape them
[21:44:24] <Loetmichel2> ... but dont try to make it a CNC
[21:44:30] <Roguish> 4hp spindle.
[21:45:06] <Loetmichel2> i have seen one in action a few years ago
[21:45:13] <Roguish> Loetmichel2: like I said, it may not hold super tight accuracies, but it's a very good mill.
[21:45:20] <Loetmichel2> but supposedly an older model, smaller and more "round"
[21:45:27] <rabbitfoo> Slides are good, and it used to do half thou precision before the control died.
[21:45:29] <furrywolf> Loetmichel2: it's already CNC. it just has a bad control. read what he said!
[21:45:35] <Loetmichel2> impressive but too small for my tastes

[21:46:16] <PetefromTn_> ya know so we don't have to guess

[21:49:01] <rabbitfoo> nah. Got some renco encoders to fit ;)
[21:50:01] <rabbitfoo> servo drives *should* be OK
[21:50:10] <furrywolf> googling shows that control was pretty useless even from the factory. lol
[21:50:33] <ThisSucks> You could get a lot done with it
[21:50:42] <ThisSucks> I used to run one
[21:50:43] <Roguish> interesting. that mill has the quill motorized. mine has the knee motorized.
[21:50:51] <furrywolf> in that case, give Mesa a few bucks (ask pcw_home for suggestions on which boards you need), and it should be an easy retrofit.
[21:51:45] <rabbitfoo> I was going to use the original IO board (maybe with a mesa card), but....
[21:51:50] <furrywolf> "145 is a 2 1/2 axis, does not do helical or 3d contouring" also has a 1000 line limit, so you can't send anything complex to it anyway. so, not useless, but definitely limited in features.
[21:52:43] <rabbitfoo> TNC145 *did* helical moves *IF* you programmed it right
[21:52:54] <syyl> and it did dnc
[21:53:05] <syyl> so you could run programs as big as you want

[21:55:34] <syyl> yes rabbitfoo
[21:55:38] <furrywolf> rabbitfoo: no, it's not worth retrofitting, and that mill isn't worth anything more than scrap metal.... I'll give you $200 and haul it off for you.
[21:55:47] <Roguish> know what happens to a Heidenhain control when you pull the battery out and shut it down?

[22:06:48] <Roguish> furrywolf: u referring to big john T?
[22:06:58] <rabbitfoo> 7i37 does not provide enough IO
[22:07:22] <furrywolf> Roguish: no, I just found some web page on a series II conversion that used those boards, and was wondering if it was your page.
[22:07:22] <andypugh> I would use the 5i24 rather than 5i20 nowadays, smaller, more powerful, cheaper.
[22:07:54] <Roguish> i like to 7i37 'cause it's isolated. i'm pretty good at letting magic smoke out of anything/everything.
[22:07:56] <andypugh> Or the 5i25 + 7i77
[22:08:48] <Roguish> the short of it all is that it's a very easy convert. and well worth it.
[22:08:52] <furrywolf> rabbitfoo: the 7i77 probably does most of what you need, and you can plug an i/o board into it if you need more.
[22:09:27] <furrywolf> http://store.mesanet.com/index.php?route=product/product&product_id=120
[22:10:09] <Roguish> furrywolf: sadly I have never documented my conversion. might get to that some day.
[22:10:19] <furrywolf> "6 Axis of analog servo motor drives and also provides 48 isolated I/O points for general purpose field I/O use."
[22:11:16] <andypugh> Thats 32 inputs and 16 outputs, but he said he needed 19 outputs
[22:12:18] <pcw_home> you could use the 5I25's P2 TTL outputs for the last 3 if 5V signals were enough
[22:12:27] <rabbitfoo> To be honest, IO card is not a problem - Got a PCI card with three 8255 chips on it.
[22:12:35] <furrywolf> http://store.mesanet.com/index.php?route=product/product&path=69_70&product_id=113 would give you another 48 pins. :)

[22:33:09] <CaptHindsight> maybe that's why people reinvent the wheel vs improve Linuxcnc, no experience with Fortan and Cobol :)
[22:33:33] <pcw_home> NML should probably just be replaced but its a big job
[22:33:53] <rabbitfoo> but here is a good one, try: ./configure --diable-python --without-python
[22:33:56] <andypugh> I grepped the remains of the backup and found emails from 2004, so a Python script should rescue my email archive. All in all I almost feel liberated by the fresh start
[22:34:48] <andypugh> rabbitfoo: If you have an appetite for extensive changes to the LinuxCNC codebase, look at Machinekit.
[22:35:09] <furrywolf> andypugh: make a backup of your backup, create zero-filled files for the missing bands, try fscking it and see what's left.
[22:35:33] <rabbitfoo> um, no thanks - I've seen some of the discussions on the mailing list.
[22:35:53] <zeeshan|2> whats wrong with python
[22:35:59] <andypugh> furrywolf: I was thinking of creating another backup then copying the old backup over the top of it.
[22:36:01] <furrywolf> a lot :P
[22:36:13] * Tom_itx puts zeeshan|2 in a delay loop
[22:36:32] <XXCoder> while(1==1){}
[22:36:34] <furrywolf> andypugh: nulls are probably better than sorta-looking-like-the-right-data-but-not-quite...
[22:36:36] <rabbitfoo> python has its uses (somewhere)
[22:36:44] <andypugh> rabbitfoo: The point of using Python is that it allows users to reconfigure the system without recompiling LinuxCNC.
[22:37:23] <rabbitfoo> andypugh: You are missing the point.
[22:37:25] <zeeshan|2> i like python!
[22:37:35] <rabbitfoo> go try: ./configure --diable-python --without-python
[22:37:49] <rabbitfoo> and see where it goes tits up
[22:37:59] <andypugh> Nearly everywhere, at a guess
[22:38:58] <andypugh> I think we all look at the code and go “eew!” some of the time, but that’s a poor reason to change something that it known to work and has been well tested.

[22:40:28] <andypugh> zeeshan|2: I do that sort of thing wih CNC :-)
[22:40:41] <zeeshan|2> dont abuse your mill
[22:40:43] <zeeshan|2> you showed me!
[22:40:52] <andypugh> (but only because I don’t have your cool machine)
[22:41:30] <zeeshan|2> this machine is so neglected
[22:41:35] <zeeshan|2> first time using it in a 1 year
[22:41:43] <andypugh> I am keeping an eye out for a cheap Jenny like that
[22:42:20] <zeeshan|2> jenny?
[22:42:27] <andypugh> Hmm, actually, _any_ sort of chaep Jenny might be cool
[22:42:30] <CaptHindsight> andypugh: ever work with the deposition of polymer thin films (no metals) ~10-500nm thickness? Wondering what you used if so.

[22:43:37] * rabbitfoo has done a little thin-film on glass
[22:44:09] <CaptHindsight> rabbitfoo: polymers or metal oxides?
[22:44:40] <rabbitfoo> silver crystals in gelatin matrix
[22:46:09] <rabbitfoo> if you want large volume thin film coatings on flexible substrates, I know the guys to talk to
[22:46:41] <andypugh> zeeshan|2: https://www.youtube.com/watch?v=QA_diGxOREQ Calls it a Jenny. I believe that to be one of the names fhr them.
[22:46:52] <zeeshan|2> oo
[22:46:54] <zeeshan|2> that looks nice
[22:47:03] <andypugh> CaptHindsight: No, I have hardly used polymers at all.
[22:47:21] <rabbitfoo> and how many layers do you need ?
[22:47:26] <andypugh> AFK (Eating a rather late dinner)
[22:47:34] <zeeshan|2> i like those gear dies
[22:47:39] <CaptHindsight> rabbitfoo: these are polymer thin films on polymers on the sub-micron scale
[22:47:51] <zeeshan|2> CaptHindsight: there is a ton of paper on the subject
[22:48:20] <CaptHindsight> zeeshan-lab: I know. Just wondering what Andy might ave used/
[22:48:58] <rabbitfoo> what size substrate are you coating ?
[22:49:16] <CaptHindsight> zeeshan-lab: unlike yourself I know how to perform my own research :)
[22:49:40] <zeeshan|2> ??
[22:50:06] <CaptHindsight> rabbitfoo: from few nm^2 to maybe 2bm^2
[22:50:17] <CaptHindsight> 2cm^2
[22:51:35] <rabbitfoo> OK... The people I know are geared for 1.5m wide by 5,000m (min) lengths in production volumes
[22:51:55] <rabbitfoo> The test line can do 300mmx2m
[22:52:28] <CaptHindsight> yeah, not that application
[22:52:59] <rabbitfoo> and they can coat up to 14 layers at a time
[22:53:22] <rabbitfoo> (5 on the test line)
[22:54:19] <zeeshan|2> CaptHindsight: i came across the paper when searching for bulge testing of polymers :)
[22:55:25] <CaptHindsight> really tiny tiny paint brush?
[22:56:05] <rabbitfoo> Are you wet coating ?
[22:56:53] -!- Camaban has quit [Quit: Leaving]
[22:57:02] <CaptHindsight> it can be wet or dry, but dry is much faster for this process
[22:57:49] <rabbitfoo> sounds like you have already got your coating methods in mind then...

[23:08:14] <CaptHindsight> say you want to put rubber-soled shoes on the spider in the pic, vs just barefoot, or polyester shirts on the nude busts
[23:11:52] <rabbitfoo> For that size of coating, spin coaters would be ideal
[23:12:46] <rabbitfoo> but they work best with wet coatings

[23:24:52] <CaptHindsight> a layer of something polar on ptfe would fly right off

[23:45:41] <andypugh> I can see a fundamental error in your spelling :-)
[23:47:28] <furrywolf> I decided a while ago that all fundamentalists had serious errors. :)
[23:47:58] <rabbitfoo> Do you want an honest exchange or discussion about the code ?
[23:48:36] <rabbitfoo> or are you going to jumping on spelling all night ?
[23:49:13] <furrywolf> if you don't actually say what you believe the error to be, what kind of answers do you expect?
[23:49:55] <rabbitfoo> There appears to be a basic misunderstanding of what the volatile keyword does.
[23:50:04] <XXCoder> rabbitfoo: https://goo.gl/nUoodz heh
[23:51:03] <PetefromTn_> I just don't understand fundamentally speaking what the hell you guys are talking about...
[23:51:27] <Tom_itx> they are critiquing the way linuxcnc has been written
[23:51:38] <CaptHindsight> all software beyond 1's and 0's is voodoo!
[23:51:46] <PetefromTn_> oh that's a great idea
[23:51:51] <Tom_itx> just shove it thru a black box
[23:52:07] <XXCoder> CaptHindsight: evenually there will be 3 bit, 1, 0, and -1
[23:52:57] <CaptHindsight> way back when I predicted 7bit bytes, oh so close
[23:53:21] <rabbitfoo> There is zero need to have configuration data declared as volatile for starters.
[23:53:26] <PetefromTn_> that bytes
[23:53:38] <furrywolf> rabbitfoo: it's been a while since I've used it, but as I remember, volatile tells the compiler that the memory location storing the variable may change at any time, for reasons other than the code the compiler is compiling. this could be because it's memory mapped i/o, for example, or it could be because it's being modified from another thread. how are they using it contrary to this?
[23:54:20] <PetefromTn_> so does that mean you are going to rewrite it and make it all better?
[23:54:41] <rabbitfoo> Not tonight Pete
[23:54:51] <CaptHindsight> PetefromTn_: https://www.youtube.com/watch?v=lf5OMQbcJ90 newish treatments
[23:55:28] <furrywolf> variables being modified by an ISR would be another good use of it.

[23:56:30] <PetefromTn_> CaptHindsight That is freaking awesome man is that something you are working on?
[23:56:30] <furrywolf> declaring something volatile that isn't has no functionality issues, just prevents optimization, turning every use into a L1 cache fetch instead of a register...
[23:56:49] <CaptHindsight> not directly
[23:57:16] <rabbitfoo> optimization (or the lack of) is one issue
[23:57:38] <PetefromTn_> I need to get myself somehow involved in that sort of thing both for work and for helping people somehow in my life
[23:57:55] <rabbitfoo> volatile does not guarantee ordered read/writes
[23:58:00] <furrywolf> rabbitfoo: so how are they using it that demonstrates a fundamental misunderstanding of its purpose?
